I. COMPETITIVE OVERVIEW

The Commission conducted its last comprehensive review of local exchange competition in 1999. Since that time, CLEC customer bases have been growing at significant rates, more than tripling in the last three years. ILECs are losing roughly an equal number of lines to wireless and cable networks as they are to wireline CLECs. At least 10 million wireline access lines already have migrated to wireless networks, and several million more have migrated to cable networks. For three years running, the number of lines served by ILECs has declined – a trend never witnessed before in a century of growth of telephone service. And competitive alternatives are available to far greater numbers than are actually subscribing today.

A. Competitive Facilities and Networks.

The competitive networks of CLECs, wireless carriers, and broadband providers have all grown significantly in the three years since the Commission conducted its last comprehensive UNE review. See Table 1. The number of cities with CLEC networks has increased by more than 70 percent, CLEC fiber has grown by more than 80 percent, CLEC circuit switches and packet switches have both nearly doubled, and buildings served by CLECs have more than tripled. See id. CLECs now serve more lines using entirely their own facilities (including their own local switches and loops) than they do by relying entirely on ILEC networks (through resale or the UNE Platform). See Figure 1. All of these figures are conservative, because they are drawn from public sources or from the necessarily limited data available to the BOCs.

Figure 1. Breakdown of CLEC Lines by Mode of Entry*

Resale 13%

Entirely Over CLEC Facilities UNE Platforms 52% 23%

Using CLEC Switches and UNE Loops 12%

*The number of lines provided entirely over CLEC facilities and using CLEC switches is based on the number of E911 listings CLECs have obtained. Because the actual number of lines that CLECs are serving with their own switches is likely much higher, this method will, if anything, understate the percentage of all lines that CLECs are serving in whole or in part over facilities they have deployed themselves. The number of lines that CLECs are serving entirely over CLEC facilities was derived by subtracting the total number of stand-alone POTS loops from the total number of CLEC E911 listings.

Switches.1 At the time of the last UNE review, CLECs had deployed approximately 700 traditional local circuit switches. Today, CLECs operate approximately 1,300 known local circuit switches. CLECs are now using their switches to serve no fewer than 16 million local lines, and likely closer to 23 million local lines, a more than three-fold increase since 1998. CLEC switches are now so geographically widespread that they are being used to serve actual local customers in wire centers that contain approximately 86 percent of the Bell companies’ access lines.

CLECs are using their switches to serve mass-market customers as well as large business customers. As of year-end 2001, CLECs were serving at least three million residential lines using their own switches, and were offering service to millions more. Circuit-switched cable telephony has been deployed in 20 states and is now available to more than 10 million U.S. homes – approximately 10 percent of the mass market. Cable telephony is now available ubiquitously in some smaller states (e.g., Cox service in ) and to a large and growing fraction of homes in a number of larger states (e.g., AT&T service in and around Pittsburgh, , Chicago, and the Bay Area, and Cox service in San Diego, Orange County, and the Tidewater area of Virginia).

Packet and wireless switches are now placing significant, additional competitive pressure on the ILECs’ traditional circuit switches. Some eight million users now have broadband cable or wireless data links that terminate directly on a competitive packet switch, bypassing ILEC circuit switches altogether. Since the last UNE review, the installed base of the CLECs’ known packet switches has nearly doubled, from 860 to more than 1,700. The number of wireless subscribers has increased from about 69 million as of year-end 1998, to an estimated 130 million today. A rapidly growing number of subscribers are using wireless service as a substitute for second and additional lines, and some consumers have abandoned wireline service entirely in favor of wireless. And wireless switches are displacing usage on wireline switches even more

I-2

rapidly. Wireless carriers have deployed hundreds of switches, which handle an estimated 12 percent of all U.S. phone calls.

Interoffice Transport.2 It is clearly economical for competitors to run fiber-optic networks to a large fraction of ILEC wire centers. Since the time of the last UNE review, CLECs have increased their fiber networks from approximately 100,000 route miles to at least 184,000 route miles, and the majority of this fiber is used for local transport. The number of CLEC networks in the 150 largest MSAs – which encompass nearly 70 percent of the U.S. population – has grown from approximately 1,100 to approximately 1,800 in the last three years. Local fiber also is now being supplied to CLECs by carrier-agnostic wholesale suppliers, utility companies, and interexchange carriers. CLECs are now using their own fiber networks to capture between 28 and 39 percent of all revenues for special access services, which are provided through a combination of transport and high-capacity loops.

CLECs that provide competitive transport typically do so by collocating transmission equipment in an ILEC central office and connecting that equipment to their own fiber-optic network. This “fiber-based collocation” supplies the simplest and most unambiguous indicator of the extent of competition in the transport market. As of year-end 2001, one or more CLECs had obtained fiber-based collocation in BOC wire centers that contain more than half of all business lines served by the Bell companies. As of that same date, one or more CLECs had obtained fiber-based collocation in more than 60 percent of all BOC wire centers with more than 10,000 business lines. These figures are highly conservative because, with all the competitive fiber that has been deployed, a considerable amount of traffic also now bypasses ILEC wire centers completely.

High-Capacity Loops.3 CLEC fiber networks now pass through a large number of commercial office buildings, which contain an even larger number of high-volume customers. CLECs now serve at least 156 million voice-grade equivalent circuits, the majority of which are provided over high-capacity lines. And CLEC fiber networks are now so extensive that they readily can be – and routinely are – extended as needed to pick up additional traffic from new, off-net customers. CLECs accordingly serve the vast majority of their customers using their own last-mile facilities. For example, CLECs serve between four and seven times more business customers over high-capacity fiber that the CLECs own themselves, than they do over loops obtained from ILECs. CLECs have purchased only 70,000 high-capacity loops in the four BOCs’ regions combined. Virtually all of the high-capacity loops that CLECs have purchased are DS-1 loops; CLECs have purchased only 140 DS-3 loops, and not a single loop above the DS-3 level.

POTS Loops.4 Technologies that compete directly against traditional POTS loops are rapidly being deployed across the country. Cable telephony services were available in only a few markets at the time of the last UNE review. Today, they have been expanded to the point where they are now offered to more than 10 percent of all U.S. homes; that figure is projected to

2 See Section III. 3 See Section IV.A. 4 See Section IV.B.

I-3

rise rapidly over the next few years. As noted above, cable telephony is now available ubiquitously in some smaller states and to a large and growing fraction of homes in a number of larger states.

Wireless services compete much more significantly against wireline than they did at the time of the last UNE review. The quality of wireless services has improved significantly in the last three years, and prices have dropped dramatically. More than 90 percent of the U.S. population now lives in counties served by three or more mobile wireless operators; more than three-quarters of the population live in counties served by five or more. Two in five Americans have a mobile phone.

Broadband Loops.5 Broadband loops represent an increasing share of all loops provided to mass-market customers – more than 6 percent as of year-end 2001. Broadband cable modem service is now available to more than two-thirds of the residential population. Cable operators serve more than twice the number of broadband subscribers as ILEC networks, and satellite and fixed wireless providers offer additional competition. Two satellite providers now offer two-way broadband service nationwide. Broadband wireless services also are much more widely available today than they were three years ago.

Interconnection of Competitive Networks and ILEC Networks. Since the last UNE review, CLECs have significantly increased the level of interconnection between their networks and ILEC networks, and the amount of traffic exchanged between them. See Table 2. The number of CLEC collocation arrangements has grown nearly six-fold since the Commission conducted the last UNE review. See id. End offices serving more than 80 percent of all BOC access lines now have one or more CLEC collocators.6 The number of CLEC interconnection trunks has more than quadrupled since the last UNE review. See Table 2. Minutes of traffic exchanged on these trunks have increased by about five-fold. See id.

B. Competitive Lines Served.

Since the last UNE review, CLECs, wireless, and broadband providers have very significantly increased the number of customers and lines that they serve. See Table 3. There has been especially large growth in the number of lines that CLECs serve with their own facilities. By contrast, ILEC access lines have steadily declined in each of the last three years, an unprecedented trend in a century of steady annual growth. See Figure 2.

CLECs serve no fewer than 16 million lines and likely closer to 23 million lines – including approximately three million residential lines – wholly or partially over facilities they have deployed themselves, facilities that invariably include their own local switches.7 These line totals represent a more than three-fold increase since 1998, and a more than thirty-fold increase in facilities-based residential lines. Many of the lines that CLECs serve are high-capacity lines; CLECs now serve at least 156 million voice-grade equivalent circuits.8 CLECs also serve more than 9 million lines – including more than 5 million residential lines – via resale of ILEC service or through the UNE Platform. The corresponding figures three years ago were approximately 2.7 million CLEC lines, including 1.5 million residential lines. Today, the largest CLECs serve more than one million access lines each, and large numbers of CLECs serve 500,000 or more. See Figure 3.

The CLECs’ share of access lines in BOC regions is at least 16 percent, and likely closer to 20 percent. See Figure 4. Their share of BOC residential lines is approximately 9 percent, and their share of BOC business lines is at least 26 percent, and likely closer to 33 percent. In some BOC regions, the CLECs’ share of lines is even higher. And, as noted above, at least two- thirds of all CLEC lines are provided wholly or partially over facilities they have deployed themselves.

*The totals for facilities-based lines based on interconnection trunks multiplied by 2.75 represents the additional lines produced by this methodology over the number of E911 listings that CLECs have obtained. **Verizon data do not include CLEC or ILEC lines in the former GTE service area. ***SBC data do not include CLEC or ILEC lines in and Nevada.

Even at their lower end, the totals for facilities-based lines that we report here are considerably higher than the totals that CLECs themselves have reported to the FCC for incorporation into the FCC’s February 2002 Local Telephone Competition Report. As discussed in Appendix A, however, our low-end totals have been obtained from CLEC-supplied listings in the E911 databases. For obvious reasons, these databases are highly reliable; ILECs and CLECs alike have the strongest possible incentives to maintain them accurately. In filing their line-total reports with the FCC, by contrast, many CLECs do not appear to be following the Commission’s express instructions relating to the conversion of high-capacity lines into “voice-grade equivalent lines.”9 In contrast, the CLECs do make a distinction between lines and “voice-grade equivalents” in the reports they make to investors and securities regulators. See Table 4. The Commission indicates that CLECs collectively report serving a total of only 8.6 million lines wholly or partially over their own facilities. Yet AT&T alone has informed the investment community that the company serves “over 30 million” voice-grade equivalent lines over its own network. And 11 other CLECs that report their voice grade equivalent lines to investors have reported serving an additional 125 million voice-grade equivalent lines.

9 The FCC’s instructions specify that carriers are to report “voice-grade equivalent lines,” which it defines as “a line or channel that directly connects an end user to a carrier and allows the end user to originate and terminate local telephone calls on the public switched network.” FCC, Instructions for the Local Competition and Broadband Reporting Form, FCC Form 477 at 5-6 (data as of Dec. 31, 2001) (emphasis in original).

As the totals for facilities-based competition make clear, CLECs have achieved significant economies of scope and scale, and have done so largely without relying on UNEs. More than half of all competitive lines are served entirely over CLECs’ own facilities, and nearly two-thirds of competitive lines are served by CLECs’ own switches. See Figure 1, supra. Moreover, these totals demonstrate that CLECs have chosen initially to focus on the most lucrative customer segments, and have therefore made much larger inroads than their count of lines would suggest. Indeed, as discussed below, the CLECs’ share of revenues is considerably higher than their share of lines.

I-8

To the extent that CLECs continue to rely on the UNE Platform, market experience demonstrates that they are not migrating UNE-Platform customers to their own facilities to any significant degree (if at all) – despite the fact that they have already deployed the switches they need to do so, and have already built up very large customer bases. See Figures 5 & 6.10 Indeed, many CLECs that have obtained UNE Platforms concede that they have no plans to convert these customers to their own switches. Contrary to the intent of the Commission’s unbundling rules, these CLECs are treating UNE-Platform competition as an end in itself, rather than as a stepping stone to facilities-based competition. And in doing so, they are devaluing the efforts of CLECs that have decided to make the investment in facilities-based competition.11

10 See Sections II.A & V.B. 11 See Section V.B.

I-9

ILECs are also rapidly losing lines due to competition from wireless and cable providers.12 Wireless phones compete directly for second lines, and to a lesser (but growing) extent for primary lines. Analysts estimate that about 10 million total access lines were replaced by wireless lines as of year-end 2001. Approximately 70 percent of all residential broadband subscriber lines are provided over cable networks, and two out of every three new broadband subscribers choose cable modem service.

Finally, a great deal more traffic is migrating off of ILEC networks than the migration of lines would indicate.13 E-mail and instant messaging (IM) now substitute for a large fraction of voice traffic. There are now 900 million e-mail accounts in the U.S. and over 60 million IM users. It is estimated that consumers in the U.S. are sending approximately 3.2 billion e-mail messages and approximately 1 billion IM messages per day. If only 10 percent of the 4.2 billion daily e-mail and instant messages substitute for a voice call, that is equivalent to about 750 billion minutes per year, or roughly one-third of all voice traffic that passes through ILEC networks. A large and growing fraction of e-mail and IM traffic originates and/or terminates on competitive networks. And even when carried over ILEC networks, such traffic displaces significant usage-sensitive (e.g., per-minute or per-call) revenues that otherwise would be earned.

C. Capital Investment.

CLECs, wireless carriers, and broadband providers have made enormous capital expenditures to expand the availability of their services.

CLECs have invested about $50 billion in new capital expenditures since the time of the last UNE review three years ago.14 Significant venture capital has gone into the telecommunications industry.15 CLECs also have raised large sums from strategic and institutional investors,16 and have obtained significant additional funding from debt markets.17

12 See Sections II.B & IV.B. 13 See Sections II.B & II.C. 14 See ALTS, The State of Local Competition 2001 at 20 (Feb. 2001) (citing Paine Webber and NPRG). 15 In the four full years preceding the UNE Remand Order, the telecommunications industry had attracted only $5 billion in venture capital dollars. In 1999 alone, the telecommunications industry raised nearly $8 billion, and in 2000 the industry raised an additional $18 billion. Telecommunications continued to attract significant additional venture capital in 2001, raising nearly $6 billion in venture capital funding. See PricewaterhouseCoopers, PricewaterhouseCoopers/Venture Economics/National Venture Capital Association MoneyTree Survey, Investments by Industry 1995-2001, http://www.pwcmoneytree.com/PDFS/National%20Aggregate%20Data%2095Q1%20- %2001Q4.xls. 16 CLECs raised more than $7.4 billion from strategic and institutional investors in 1999, plus another $3 billion in 2000 and 2001. See ALTS, The State of Local Competition 2001 at 17-18 (Feb. 2001) (1999); W.T. Scott, et al., Morgan Stanley, A Brief Critique – CLEC Events of the Week at 12 (Dec. 12, 2001) (2000/2001); XO Press Release, XO Announced $800 Million Equity Investment from Forstmann Little and Telmex (Nov. 29, 2001); XO Press Release, XO Reaches Definitive Agreement with Forstmann Little and Telmex (Jan. 16, 2002). In addition to these totals, Bill Gates’s private investment groups have invested $500 million in Cox. See Reuters, Gates Invests $500 Million in Cox, CNET News.com (Jan. 24, 2002), http://news.com.com/2100-1001-822792.html. 17 According to one source, CLECs obtained $36 billion in loans in 1999. See NPRG CLEC Report 2002, 15th ed., Ch. 2 at 6.

I-10

Initial public offerings by CLECs raised $2.6 billion in 1999 and 2000.18 CLEC market capitalization has dropped sharply in the past 18-24 months, as it has in most other high-tech sectors. But many CLECs took advantage of the stock bubble, while it lasted, to finance acquisitions, investments, and capital outlays. See Table 5. More recently, stronger CLECs have taken advantage of falling stock prices to purchase their weaker siblings at a bargain price.19

Much of this competitive investment has gone into building urban fiber networks to serve business customers. But CLECs also have invested a great deal in building out their networks to serve residential customers. Cable operators have already invested at least $8 billion to upgrade their networks to provide telephony services.20

Cable operators and other competitive providers also have invested heavily to provide broadband services. The National Cable & Telecommunications Association (NCTA) estimates that the cable industry has invested more than $55 billion “to provide consumers advanced broadband services” since passage of the 1996 Act.21 Satellite and fixed wireless providers also have made very large investments to provide two-way broadband services.22

There has been even more investment in terrestrial wireless facilities. Cumulative capital investment in the wireless industry has jumped from $24 billion at the end of 1995 to $100 billion as of June 2001.23 Wireless carriers spent more than $18 billion in 2000 alone on network upgrades and expansion.24 The cumulative capital investment in the wireless network ($100B) is now roughly one-quarter of the cumulative (depreciated) capital investment in the wireline network ($360B).25 Annual capital spending on the wireless network ($18B) is running at about half of the corresponding figure for the wireline network ($40B), and continues to grow more

D. Revenues.

Though precise figures of CLEC local revenues are elusive,27 facilities-based CLECs are now generating substantial revenues. According to New Paradigm Resources Group’s CLEC

26 Compare FCC Statistics of Common Carriers at Table 2.7 (1995-2001 eds.) with CTIA’s Semi-Annual Wireless Industry Survey Results. 27 Many CLECs are not public companies and do not therefore report their revenues to the Securities Exchange Commission. While most CLECs do report revenues to the FCC, the FCC releases this data in only aggregate form. Complicating matters, the revenue categories reported by the FCC have fairly amorphous parameters. For example, it is difficult to distinguish revenues generated from exchange access services from those generated from intraLATA toll and special access services. This is particularly true with respect to those revenues generated by I-12

Report – a source relied on by the CLEC industry28 – total CLEC revenues (excluding long distance revenues) increased five-fold between year-end 1998 ($8.5B) and year-end 2001 ($44B). See Figure 7.29 New Paradigm estimates that CLEC revenues from switched local services increased from $3.5 billion in 1998 to $9.5 billion in 2001.30 The latest revenue data compiled by the FCC show CLECs with a total of $8.5 billion in local revenues as of year-end 2000.31 Since the time of the last UNE review, the number of CLECs earning $100 million or more has nearly doubled. See Figure 8.

CLECs specifically target customers that generate high levels of traffic and revenues32 – analysts and the FCC report that the CLECs’ share of revenues is between 12 and 20 percent higher than their share of lines.33 And the CLECs’ share of high-end local services is considerably higher than their share of local revenues overall. For example, the CLECs’ share of special access revenues is between 28 and 39 percent.34 The big three interexchange carriers control more than two-thirds of the revenues for ATM and Frame Relay services.35

CLECs that provide local services also earn significant revenues from the provision of other telecommunications services. According to New Paradigm, CLECs now earn nearly $25 billion from the provision of data and data-related services such as Internet access, frame relay, carriers that are both CLECs and interexchange carriers, including AT&T and WorldCom – the largest carriers in both categories – who report their revenues as both kinds of entities. See Appendix L. 28 See, e.g., ALTS, The State of Local Competition 2001 (Feb. 2001); ALTS, An ALTS Analysis: Local Competition Policy & The New Economy (Feb. 2, 2001); ALTS, The State of Competition in the U.S. Local Telecommunications Marketplace (Feb. 2000). 29 See NPRG CLEC Report 2000, 12th ed., Ch. 1 at Table 3; NPRG CLEC Report 2002, 15th ed., Ch. 3 at Table 9. “Other” revenues reported by New Paradigm (i.e., reciprocal compensation and non-telecom related revenues) are excluded from these totals. Credit Suisse First Boston estimates that total CLEC revenues (excluding long-distance and data revenues) have grown from approximately $5 billion in 1998 to approximately $12.5 billion in 2001. See CSFB 4Q00 CLEC Vital Signs Review at Table 11 (4Q1998); CSFB 3Q01 CLEC Vital Signs Review at Exh. 9 (1Q 2001-3Q 2001 results; 4Q 2001 estimate). 30 Compare NPRG CLEC Report 2000, 12th ed., Ch. 1 at Table 3 with NPRG CLEC Report 2002, 15th ed., Ch. 2 at Table 8. Credit Suisse First Boston estimates that CLEC revenues from switched local services has increased from approximately $3.7 billion in 1998 to $10.8 billion in 2001. See CSFB 4Q00 CLEC Vital Signs Review at Table 11 (4Q1998); CSFB 3Q01 CLEC Vital Signs Review at Exh. 9 (1Q 2001-3Q 2001 results; 4Q 2001 estimate). 31 FCC Telecommunications Industry Revenues, 2002 ed. at Table 7; NPRG CLEC Report 2002, 15th ed., Ch. 2 at Table 8. 32 See, e.g., Legg Mason, Telephone Wars: Local Competition Update at 2 (May 22, 2001) (“The CLEC sales figures reflect larger market share gains than those calculated on the basis of line lost, since the majority of lines lost are of the high-usage commercial type.”). 33 See, e.g., id. at 3 (At the end of 1Q01 “the CLEC share of the total US line market was 7.6%,” while “the CLEC’s share of the gross industry revenues was approximately 9.2%,” a difference of 21%.); FCC Local Competition Report, Feb. 2002 ed. at 4, Table 1 (“The share of local service revenues claimed by carriers competing with the ILECs” was 8.9% in 2000 while CLECs reported a 7.7% share of end-user switched access lines in December 2000, a difference of 15.6%); CSFB 3Q01 CLEC Vital Signs Review at Exh. 9 (Through 3Q01, local competitors’ share of U.S. access lines was 9.7%, while local competitors’ share of the local market revenues at quarter end was 10.9%, a difference of 12.4%). 34 See Section V.C & Appendix L. 35 See Section II.B, Figure 5.

ATM, DSL, “and other enhanced data and Web-related services.”36 CLECs other than the big interexchange carriers earn an additional $3 billion from the provision of long distance services.37 Cable telephony providers are able to bundle video and data services with the voice services they provide, and analysts expect “video/voice” to be the “most popular” bundle of service desired by consumers.38

If cable companies are counted among them, CLECs earn substantial revenues in the local, high-speed data transport sector as well. Cable companies earned an estimated $2.3 billion from the provision of high-speed data services in 2001, and that figure is projected to exceed $10 billion by 2006.39

Wireless carriers also are competing directly with ILECs for a large and increasing share of revenues. As of year-end 2000, wireless carriers reported $62 billion in revenues, which

represents more than half of the revenues that wireline carriers reported for local service.40 At the time of the last UNE review, wireless revenues were at $37 billion, about one-third the amount of wireline local revenues.41

E. Outlook.

As a percentage of the overall telecommunications market, wireline local voice is rapidly declining, as local traffic moves on to wireless and data networks, and the volumes of data traffic continue to surge. See Figure 9. Wireline local voice revenues grew by an average of 2.7 percent per year between 1996 and 2001, but are expected to remain constant over the next five years.42 While wireline local voice revenues represented approximately 44 percent of all local revenues in 2001, they are expected to represent only 26 percent by 2006.43

Cable telephony providers are expected to “have more than 10 million circuit-switched telephony customers in 2006.”44 Cable operators will have deployed IP-telephony widely by that time as well, and are expected to serve nearly five million telephony customers over packet- switched networks.45

Data traffic has already overtaken voice traffic on the telephone network, and data traffic is growing much faster than voice. Most access-line growth between 1996 and 2000 was due to data, with customers adding second lines as a dedicated Internet/fax line.46 These lines are now

I-15

in rapid decline, with most customers opting for a wireless or cable connection instead of a second line.47 By 2006, it is expected that 17 million circuit-switched lines will have been superceded (i.e., rendered technologically obsolete) by wireless, cable modem, and non-DSL packet-switched connections.48 Local data revenues are expected to grow to nearly $70 billion in the next five years.49 By that time, data is expected to make up 46 percent of all local revenues, up from 24 percent today. See Figure 9. A great deal of data traffic is carried on non-ILEC networks. Cable modem is adding residential broadband subscribers much faster than DSL, and cable is expected to maintain a two-to-one lead over DSL five years from now.50

Wireless carriers are adding subscribers much faster than their wireline counterparts – in percentage terms, and in absolute terms, too. Some twenty million new subscribers are being added annually.51 IDC estimates that, by 2005, wireless “lines” will have cumulatively displaced a total of approximately 20 million wirelines (counting both primary and secondary access lines).52 Wireless minutes of use are growing at over 60 percent per year, while landline minutes are growing at “low single digits.”53 By 2003, wireless voice revenues are expected to surpass wireline voice revenues. See Figure 10.

Next-generation broadband technologies are now being deployed.54 Much of the copper distribution plant will have to be replaced with fiber in order to support the growing demand for broadband services. Wireless broadband services – both fixed and mobile – are coming, too. Analysts predict that 3G mobile networks will be widely deployed by 2004 or 2005. The Commission also has recently taken the first steps to “pave the way for new types of products incorporating ultra-wideband (UWB) technology” – devices that may be able to operate on spectrum already occupied by existing radio services without causing interference. It has also resolved to explore the introduction of “software defined radio” (SDR) technology, which could allow a single device to be quickly reprogrammed to transmit and receive on any frequency within a wide range using virtually any transmission format. There also are a host of other technologies currently under development that will be capable of provisioning wireless broadband services. These include Digital SMR, third generation mobile systems, 2 GHz MSS satellite systems, L-Band satellites, and Big LEO satellites. Recent advancements in fixed wireless technologies – particularly Non-Line-of-Sight technologies – are expected to “cause a spur in service provider deployments.”

Entirely new telecommunications networks are being deployed to satisfy surging demand for high-speed packet-switched data services. Much of this new infrastructure has little relation to the old. Fiber is replacing copper in the loop; packet switches are replacing circuit switches in the central office; and the transport between these packet switches is using very different routes than the rigid point-to-point connections between central offices that have prevailed in the past. In deploying this new infrastructure, ILECs will enjoy no particular advantages over competing carriers.

Most of the broadband market that is now emerging remains up for grabs. Most of the technology that will ultimately be used to provide ubiquitous broadband service has not yet been developed. Most of the capital has not yet been committed. Most of the customers are not yet being served. And because broadband digital services will ultimately absorb and displace the old, analog voice and video, no established player in telecom, cable, or broadcast markets today has any assurance of winning any durable share of the vast digital market ahead.

II. LOCAL SWITCHING

At the time of the FCC’s last UNE review, CLECs had deployed approximately 700 local circuit switches.1 Today, CLECs operate approximately 1,300 known local circuit switches. See Appendix B.2 At the time of the last UNE review, CLECs were serving about six million lines using switches they had deployed.3 As of year-end 2001, CLECs were serving no fewer than 16 million local lines, and likely closer to 23 million local lines – including approximately three million residential lines – over their own switches. CLEC switches are now so geographically widespread that they are being used to serve local customers in wire centers that contain approximately 86 percent of the Bell companies’ access lines. In the 100 largest Metropolitan Statistical Areas (MSAs), CLECs are using their switches to serve local customers in wire centers that contain approximately 96 percent of the BOC access lines in those MSAs. See Appendix C. All of these figures are conservative, because they are drawn from public sources or from the necessarily limited data available to the BOCs.

More than 200 CLECs of all sizes have actually deployed local circuit switches in the Bell companies’ regions. While the two largest CLECs (AT&T and WorldCom) account for more than 25 percent of these switches, the next 15 largest CLECs (measured by switch ownership) account for an additional 37 percent of all local circuit switches. See Figure 1. The number of CLECs operating 10 or more circuit switches has increased from 15 to 27 since the time of the last UNE review, while the number operating 20 or more has increased from 6 to 16.4 And with the exception of AT&T and WorldCom, the 15 largest switch-based CLECs (measured by switched-based lines served) make virtually no use of unbundled switching, either on a stand- alone basis or as part of the so-called UNE-Platform. See Figure 2.

Cable companies have deployed large number of circuit switches that they are using, in combination with their own loops, to provide cable telephony service that bypasses ILEC networks completely. This service is now available to more than 10 percent of all U.S. homes and there are more than 1.5 million actual subscribers. Cable telephony is now available statewide in some smaller states (like Cox service in Rhode Island) and to a large and growing fraction of homes in a number of larger states (e.g., AT&T service in and around Pittsburgh, Boston, Chicago, and the Bay Area, and Cox service in San Diego, Orange County, and the Tidewater area of Virginia).

1 See UNE Remand Order ¶ 254 (“As of March 1999, approximately 167 different competitors have deployed approximately 700 switches throughout the country.”). 2 See Telcordia, January 2002 LERG. New Paradigm Resources Group (“NPRG”) reports that, as of year-end 2001, CLECs had deployed 1,244 circuit switches with another 92 circuit switches planned. See NPRG CLEC Report 2002, 15th ed., Ch. 2 at 20. That figure is based on the circuit switches of 70 companies profiled by NPRG. See id. By comparison, the LERG database indicates that approximately 200 competing carriers have deployed circuit switches. See Appendix B. 3 This figure is based on the number of interconnection trunks CLECs had obtained as of year-end 1998 (see Section I, Table 3), and assumes that for each trunk a CLEC had obtained as of that date, the CLEC was serving 2.75 lines. See Appendix A (describing this methodology in more detail). 4 See Section V, Figure 1.

Packet and wireless switches are now placing significant, additional competitive pressure on ILECs’ traditional circuit switches. At the time of the last UNE review, 36 million households still relied on dial-up connections – and thus on ILEC circuit switches – for their data services.5 As discussed further in Section IV.C, however, nearly eight million users now have broadband cable or wireless data links instead, which bypass the circuit switch completely and terminate directly on a competitive packet switch. If all of these broadband users would otherwise be using dial-up connections, the packet switches used to provide these services now displace at least 4 percent of all circuit-switched minutes of use, even assuming that the average data line is used only as much as the average voice line. The total would be far higher if one takes into account the fact that data calls generally last much longer than voice calls. Since the last UNE review, the installed base of CLECs’ known packet switches has jumped from 860 to more than 1,700.6 See Appendix E.

5 See JP Morgan Cable Industry Report at Table 13 (36.7 million online households in 1998 minus 700,000 broadband households equals 36 million dial-up households). 6 See NPRG CLEC Report 2000, 12th ed., Ch. 6 (1998 total); NPRG CLEC Report 2002, 15th ed., Ch. 4 at II-2

The dramatic rise of wireless services since the last UNE review is certainly having a similar impact on circuit-switched ILEC traffic. As of year-end 1998, there were about 69 million wireless subscribers; as of year-end 2001, there were an estimated 130 million, as compared to about 190 million wireline switched access lines.7 Today, a large and rapidly growing number are using wireless service as a substitute for second and additional lines, and a growing number are abandoning their wireline phones altogether. There were approximately 200 billion billable minutes of wireless use in the first half of 2001, and by the end of 2001 wireless calls accounted for an estimated 12 percent of all U.S. phone calls. Many wireless carriers offer particularly attractive long-distance calling plans; when the wireless phone is used for long-distance calls, the ILEC loses traffic not only in end office switches but in access tandems, too. Wireless carriers not affiliated with the Bell companies have deployed at least 950 local switches. See Appendix F.

A large and growing fraction of business customers also locate switching equipment directly on their premises, which enables them to perform a portion of their local switching in- house, rather than outsource it to an ILEC’s circuit switch. Today, there are approximately 56 million lines served through private branch exchanges (PBXs). A PBX performs all the local switching between the lines that connect to it directly. Moreover, a new generation of PBXs that use IP-based packet switching instead of circuit switching make PBXs economical for an even larger share of businesses.

Table 18 (2002 total). This is a highly conservative estimate. It does not include the 840 packet switches NPRG lists for competitive Independent Operating Companies, utility CLECs, data providers, or Gig-E providers. In addition, it does not include the 7,000 packet switches that NPRG lists for AT&T as of year-end 2001. According to NPRG’s prior reports, AT&T had only 50 packet switches as of year-end 2000. Because one-year growth of this magnitude is unlikely, in an abundance of caution we have used the 2000 figure for AT&T’s packet switches. 7 CTIA’s Semi-Annual Wireless Industry Survey Results; CTIA, CTIA’s World of Wireless Communications, http://www.wow-com.com (131 million U.S. wireless subscribers as of Feb. 12, 2002); CSFB 3Q01 CLEC Vital Signs Review at Exh. 9 (189 million U.S. access lines as of 4Q2001).

A. CLEC Circuit Switches.

By very conservative estimates, CLECs are serving no fewer than 16 million local lines, and likely closer to 23 million local lines – including approximately three million residential lines – over the local circuit switches they have deployed. See Table 2 & Appendix A. CLECs serve a far larger number of actual circuits using their switches, because many of the lines they serve are high-capacity lines.8

CLECs are using their switches to serve local customers in one of two ways. First, they are porting numbers from ILEC switches to their own switches using local number portability (LNP). Second, they are using NXX codes obtained from the North American Numbering Plan administrator.

8 See Sections I.B, Table 4 & IV.A; see also Appendix A.

CLECs have ported approximately 14 million telephone numbers in the Bell companies’ regions, virtually all of which have been ported since the time of the last UNE review.9 In the last year alone, the number of CLEC ported numbers has grown by more than 70 percent. See Table 3. This demonstrates that CLECs have not only significantly increased their deployment of circuit switches, but also that they are now using these switches extensively to win local customers.

1. Geographic Areas Served by CLEC Circuit Switches.

As the FCC has recognized, competition for switched services may be assessed by analyzing where CLECs have obtained ported numbers and NXX codes.10

The Bell companies maintain internal data of the wire centers in which CLECs have ported telephone numbers from the BOCs’ switches to the CLECs’ own switches.11 Each number ported from a BOC’s switch to a CLEC’s switch represents a telephone served by that competitor’s own switch. Each wire center in which a CLEC has obtained a ported number therefore represents a geographic area where a CLEC is actually competing for local customers today using switches that it has deployed itself.

9 See Telephone Number Portability, Third Memorandum Opinion and Order on Reconsideration, 13 FCC Rcd 16090, ¶ 2, n.7 (1998) (first requiring ILECs to implement LNP in the 100 largest MSAs by December 31, 1998). 10 See, e.g., FCC Local Competition Report, Aug. 1999 ed. at 2, 43, Tables 4.1-4.3 & 5.1 (summarizing NXX code assignment activity and supplying information on ported numbers which “should provide insights into the number of customer lines served by competitors”); id. at 43 (using an NXX-based analysis for identifying “new entrants in the switched market.”); id. (“A local service competitor that owns a telephone switch must acquire a numbering code for that switch before commencing operation as a facilities-based CLEC providing mass market telephone service.”); UNE Remand Order ¶ 254 (noting with approval SBC’s evidence of competition for switching “using a methodology that tracks requesting carriers’ switches by examining migration of lines using ported numbers.”); id. ¶ 285 (relying on data of CLEC switches with NXX codes as basis for creating exception to national unbundled switching rule in Zone 1 wire centers). 11 A wire center is “the location of a local switching facility containing one or more central offices.” 47 C.F.R. § 54.5; see id. (“wire center boundaries define the area in which all customers served by a given wire center are located.”); see also Policy and Rules Concerning Rates for Dominant Carriers and Amendment of Part 61 of the Commission’s Rules to Require Quality of Service Standards in Local Exchange Carrier Tariffs, Memorandum Opinion and Order, 12 FCC Rcd 8115, ¶ 7, n.14 (1997) (A wire center “might have one or several class 5 central offices, also called public exchanges or simply switches.”).

II-5

These ported number data demonstrate that CLECs are using their switches to serve local customers ubiquitously throughout the BOCs’ regions.12 As of year-end 2001, one or more CLECs had ported a telephone number to its own switch in 47 percent of BOC wire centers, which contain approximately 86 percent of all BOC switched access lines, including approximately 89 percent of all business lines and approximately 84 percent of all residential lines. See Tables 4 & 5. Significant numbers of BOC access lines are in wire centers served by multiple CLEC switches. See id.

The totals are even higher in the largest metropolitan areas. In the 100 largest MSAs, one or more CLECs had ported a telephone number to its own switch in 83 percent of BOC wire centers in those MSAs, which contain approximately 97 percent of all BOC switched access lines in those MSAs. See Appendix C.

12 For purposes of this report we have included in the analysis switches owned by CLECs that have declared bankruptcy. Most such CLECs are still operational. Moreover, switches are a sunk investment, so if one company ceases to use its switch it is highly likely that another company will quickly seize the opportunity to do so (and will probably be able to obtain the switch at a fire-sale price). In addition, even though some CLECs may now be experiencing financial troubles, the fact that they were able to deploy so many switches at one time is still highly probative of the ability of CLECs to deploy switches generally. In any event, switches operated by CLECs that have declared bankruptcy (as of March 31, 2002) represent no more than 17 percent of the total counted for purposes of this report.

II-6

The areas that CLECs are capable of serving with their own switches also can be determined based on the NXX codes that CLECs have obtained. Each NXX code is associated with a “rate exchange area” served by an incumbent LEC.13 The rate exchange areas where CLECs have obtained NXX codes are the areas where CLECs have determined they may use their own switches to compete directly with incumbent LECs.

Telcordia’s Local Exchange Routing Guide (LERG) database contains the location of each CLEC switch, the NXX codes associated with those switches, and the rate exchange areas served by those NXX codes.14 These data demonstrate that, as of year-end 2001, one or more CLECs had obtained an NXX code to serve approximately 47 percent of BOC rate exchange areas, and that significant numbers of rate exchange areas are served by multiple CLEC switches. See Table 6. In the 100 largest MSAs, one or more CLECs had obtained an NXX code to serve more than 85 percent of BOC rate exchange areas in those MSAs. See Appendix D.

The percentage of wire centers and rate exchange areas served by CLEC switches is a highly conservative measure of the extent to which CLECs actually serve – or have the ability to serve – customers using their own switches.

First, the data count only CLECs switches actually up and running, and only the locations that are presently served by these switches. CLECs could readily extend the geographic reach of existing switches, or deploy still more switches. As the Commission has found, whereas each ILEC switch typically serves only a single rate exchange area, CLECs can and do use their switches to serve multiple rate exchange areas.15 As one CLEC explains, “[t]he advent of fiber

13 Rate exchange areas are “geographically defined areas within which calls that originate and terminate (i.e., remain within the area) are considered local calls.” FCC Local Competition Report, Dec. 1998 ed. at 41, n.17. 14 In the Triennial Review Notice, the FCC asked whether the LERG database “is a reliable indication of whether competitors can serve the mass market using their own switches.” Triennial Review Notice ¶ 57. As an initial matter, while the LERG is itself a reliable source of the geographic areas to which CLECs have access with their switches, we also rely here on ported number data to make this showing. Thus, even if the Commission were concerned about the reliability of the LERG, it may rely on this alternative source of data. Moreover, as discussed below, once a CLEC has deployed a switch and is using that switch to serve business customers, it may readily expand the use of that switch to serve mass-market customers. Indeed, many competing carriers have done just that. 15 See UNE Remand Order ¶ 261 (“switches deployed by competitive LECs may be able to serve a larger geographic area than switches deployed by the incumbent LEC, thereby reducing the direct, fixed cost of purchasing circuit switching capacity and allowing requesting carriers to create their own switching efficiencies.”); id. ¶ 258 II-7

optic technologies and multi-function switching platforms have, in many cases, allowed carriers . . . to serve an entire statewide or LATA-wide customer base from a single switch platform.”16

CLECs themselves report that they can and do use their switches to serve very large geographic areas – as large as an entire LATA, an entire state, or even multiple states. AT&T has stated that its “local switches serve geographic areas that are comparable to the areas served by SWBT’s tandem switch.”17 For example, AT&T claims to serve both the entire Dallas LATA (LATA 552) and the entire Houston LATA (LATA 560) with one local switch apiece, whereas SBC serves these LATAs with 8 and 7 tandem switches, respectively, plus dozens of end-office switches.18 Numerous other CLECs have made similar claims. See Table 7.

Table 7. Use of CLEC Switches to Serve Large Geographic Areas WorldCom “WorldCom uses state-of-the-art equipment and design principles based on technology available today . . . which makes it possible to access and serve a large geographic area from a single switch.” “[W]hile WorldCom uses 4 local switches and a transport network to serve these [26] rate centers, BellSouth utilizes 5 local tandems and a multitude of end offices to serve this area.” ICG “[T]he ICG switch provides services to customers in a geographic area at least as large as that serviced by the ILEC tandem.” AT&T “It is important to note that in some cases, the AT&T switch serving a LATA is not physically located in the LATA.” Intermedia “Instead of deploying a multiplicity of switches to cover an area, as is BellSouth’s custom, Intermedia deploys a single switch to cover a very large area. Intermedia can do this because the switches it deploys are very capable and have a very large capacity.” “From this map, it is clear that all the areas we serve in Jacksonville, Orlando, Tampa and Miami are each served by a single switch. This is a great deal of territory, all covered by four Intermedia switches.” US LEC “For example, in the Jacksonville market, out network is designed to facilitate traffic termination to the same market as 2 BellSouth tandem switches. Our central office acts as tandem switch and as end office switch for the same 19 rate centers served by the two BellSouth switches.” Sources: See Appendix M.

Switch manufacturers have specifically designed their equipment to meet CLECs’ needs to serve large geographic areas.19 For example, Lucent’s 5ESS – the most popular circuit switch

(“[T]he TCG switch in Dallas serves the entire 552 LATA which SWBT also serves with 8 tandems. In Houston, the TCG switch serves the entire 560 LATA which SWBT also serves with 7 tandems.”). 19 See, e.g., Lucent Technologies, 5ESS 2000 – Switch Mobile Switching Center, http://www.lucent.com/products/solution/0,,CTID+2008-STID+10048-SOID+824-LOCL+1,00.html (5ESS provides “a unique and very attractive low-cost solution . . . to support growth opportunities in startup areas where existing II-8

CLECs also may extend their competitive reach by deploying new switches or expanding the capacity of existing switches. In the last few years, switch manufacturers have made it easier and more cost-effective than ever for CLECs to purchase and deploy new circuit switches.22 Switches have modular designs that enable a carrier to start small and add capacity as they grow.23 The latest generation of switches also has very large maximum capacities – as much as 600,000 lines.24

Second, the data are based only on conventional CLEC circuit switches, even though all forms of circuit-switched traffic (including fax, e-mail, and data) are now being switched on packet rather than circuit switches.

deploying packet switches to provide data services, and also are increasingly using these switches to provide voice services. The tabulated data also exclude wireless switches, even though wireless networks now switch at least one-quarter of the amount of voice traffic as wireline networks.25

Third, the tabulated data exclude PBXs. The FCC and independent analysts have all reached the conclusion that PBX systems compete directly with circuit-switched services.26 As of year-end 1998, there were 45 million installed PBX lines in the .27 As of year- end 2001, the number had grown to 56 million.28 This means that on approximately 44 percent of all ILEC switched access lines serving business customers at least some of the switching was done by a switch other than an ILEC’s own circuit switch.29

2. Use of CLEC Switches To Serve Mass-Market Customers.

As of year-end 2001, CLECs were serving approximately three million residential lines using their own switches. CLECs that are serving mass-market customers using their own switches have typically done so either by expanding the services on their existing large- customer-focused networks, or by expanding the geography of their existing broad-customer- based networks into adjacent territories. This service and geographic expansion typically involves the use or extension of existing facilities, not the conversion of unbundled local switching leased from an ILEC.

Service-Based Expansion To Serve Mass-Market Customers. CLECs have generally deployed switches to serve large business customers, in the first instance. Having done so, however, it is both straightforward and cost-effective for them to use these same switches to serve mass-market customers, and facilities-based CLECs are now doing so aggressively. See Table 8. Indeed, the wire centers in which CLECs already are serving business customers also contain the vast majority of all residential lines. As noted above, for example, the wire centers in

25 See note 141, infra. 26 See, e.g., Amendment of Part 69 of the Commission’s Rules Relating to Private Networks and Private Line Users of the Local Exchange, Notice of Proposed Rulemaking, 2 FCC Rcd 7441, ¶ 44 (1987) (decision to apply the surcharge to Centrex leakage as well as PBX leakage was “based upon a recognition that Centrex and PBX switches competed directly with one another.”); KLF Electronics v. Telephone, Memorandum Opinion and Order, 1 FCC Rcd 502, 503 n.3 (1986) (“Centrex service performs some of the same functions performed in a PBX, and therefore telephone exchange carriers offering Centrex compete with companies . . . that provide PBX switches.”); H.

which CLECs have ported numbers to their own switches contain 84 percent of all BOC residential access lines, in addition to 89 percent of all BOC business lines.

Cable operators have used a comparable at-the-margin strategy for getting into mass- market voice service. Here, video and data services have provided the economic entry point that has justified the initial build out of the network. The cable telephony that has been commercially deployed to date relies on the same type of circuit-switches that ILECs and CLECs use. See Table 9. At least five cable operators – including AT&T, Cox, Comcast, Cablevision and Insight – have actually deployed commercial circuit switched cable telephony.30 Circuit-switched cable telephony has been deployed in 20 states and is now available to more than 10 million U.S. homes – approximately 10 percent of the mass market.31 More than 1.5 million homes subscribe.32 Cable operators are adding over 70,000 customers a month for their residential telephony services.33 By the end of 2002, circuit-switched cable telephony is expected to be available to more than 11 percent of all homes, with an estimated 2.4 million of these homes actually subscribing.34

In some states, cable telephony is already far more widely available than nationwide averages suggest. For example, the Commission has recognized that Cox already has the “capability to provide cable telephony service to 75 to 95 percent of Rhode Island customers.”35 AT&T offers cable telephony services to large fractions of the nearly three million homes its cable network passes in the Boston Area,36 the approximately 600,000 homes it passes in the Pittsburgh area,37 the 3.5 million homes it passes in the Chicago area,38 and the 2.7 million

Kerver, Operator of the Year, Cablevision (Oct. 22, 2001). There currently are two major cable operators – AT&T and Cox – and a third smaller one, Insight, that are actively deploying circuit-switched cable telephony to new areas. See Yahoo!

Geographic Expansion to Mass-Market Customers. As discussed in more detail in Section IV.B.3, a number of incumbent local exchange carriers have been pursuing edge-out strategies, pushing into the territories of adjacent ILECs.40 For example, CTSI – the CLEC subsidiary of Commonwealth Telephone (the second largest ILEC in Pennsylvania) – operates a competitive voice network in Verizon’s service territory in Wilkes-Barre, Harrisburg, and Lancaster that serves business and residential customers.41 ALLTEL has deployed competitive facilities – including switches – adjacent to its ILEC service territories in Little Rock, Charlotte, Cleveland, Jacksonville, and Tallahassee.42

Some existing cable telephony providers also are engaging in geographic expansion, and many other cable operators could no doubt do so. For example, AT&T’s merger partner,

40 See, e.g., NPRG CIOC Report 2001, Ch. 2 at 1 (“[Competitive Independent Operating Companies (‘CIOCs’)] target RBOC markets that are geographically proximate to their existing ILEC holdings. This ‘edge-out’ strategy allows the CIOC to take advantage of the synergy of its ILEC and CLEC operations while entering typically underserved non-urban markets. CIOCs are able to employ infrastructure, brand, and local experience to gain market penetration and achieve profitability.”); id. Ch. 2 at 2 (“All CIOCs target business customers and depending on individual market characteristics, also target residential customers through the use shared lines or through infrastructure overbuilds.”). 41 See Commonwealth Telephone Enterprises, Inc., Form 10-K (SEC filed Mar. 27, 2001); NPRG CLEC Report 2001, 14th ed., Ch. 13 – CTSI, Inc. at 7; CTE Press Release, CTE Announces Restructuring of CTSI Subsidiary (Dec. 6, 2000). 42 See ALLTEL, Coverage Maps: National Map, http://www.alltel.com/news_information/maps/download/ bigjpgs/US.jpg; NPRG CIOC Report 2001, Ch. 7 at 8-9.

See ALLTEL Corp., Form 10- K405 (SEC filed Mar. 5, 2002).

Comcast, states that it can easily and cheaply use AT&T’s existing switches to provide residential telephony service to Comcast’s existing cable subscribers.43 Comcast’s Treasurer, John Alchin, states that “‘when you look at what AT&T has already done in terms of infrastructure and the huge investment they’ve made . . . we can more easily piggyback off that in an economically efficient way.’ Between 70% and 80% of Comcast’s existing systems are within ‘striking distance’ of existing AT&T Broadband switching services . . . ‘making the incremental roll-out of telephony in Comcast legacy systems compelling.’”44 Comcast plans to roll out circuit-switched phone service to as many as one million Comcast households upon closing its proposed merger with AT&T.45

Collocation and Hot-Cut Issues. As discussed in Section IV.A, CLECs that serve large business customers with their own switches typically do so directly through fiber connections they have deployed. Mass-market customers do not always generate enough traffic to justify a fiber link, so many CLECs that seek to serve such customers with their own switch will do so through an unbundled loop obtained from an ILEC. In order to do so, the CLEC will first obtain collocation in the ILEC’s central office. Where the customer that the CLEC seeks to serve already is receiving dial-tone service from the ILEC, the CLEC will typically request that a hot cut be performed on the loop serving that customer. A hot cut involves moving the end-user customer’s loop from the ILEC’s switch to the CLEC’s switch.

At the time of the UNE Remand Order the Commission declined to curtail availability of the switching UNE primarily because of the time and cost associated with obtaining collocation space and local loops through the hot-cut process.46 Concerns about collocation and hot-cut performance have been fully addressed since the time of the last UNE review, however.

43 See, e.g., Cable Companies Tell Analysts They’re Confident About Prospects, Warren’s Cable Regulation Monitor (Jan. 14, 2002) (“With switches already in place in 8 of 10 biggest U.S. markets, only $5-$50 million is needed to be invested to complete phone service for residences.”); M.

The Commission has expanded the range of collocation options and imposed standard time limits.47 And collocation in BOC regions has risen very sharply. At the end of 1998, for example, CLECs had obtained roughly 4,000 collocation arrangements in BOC regions; by year- end 2001 there were approximately 25,000 CLEC collocation arrangements in place. CLECs are now collocated in central offices that serve approximately 81 percent of BOC access lines – including approximately 79 percent of BOC residential lines. See Table 10.

The availability in the market of alternatives to traditional collocation also has been greatly expanded in recent years due to the rapid rise of alternative collocation providers (so- called collocation “hotels”), which give competitive local carriers places to deploy their switches and interconnect their networks. These companies provide “high-security facilities operated by independent companies that put telecom gear as close as possible to incumbent central offices without actually being there.”48 They permit CLECs to “easily connect with, and hand off traffic to, the IXCs and each other.”49 They allow “[m]ost new business telecom providers . . . to bypass the traditional infrastructure.”50 Today, there are alternative collocation providers in virtually all major metropolitan areas throughout the country. See Appendix G.

With respect to hot cuts, any concerns about hot-cut performance have been reduced as both sides have gained further experience and worked out the rough spots in their respective processes. Indeed, since the UNE Remand Order, the FCC has repeatedly found that BOC

performance in providing hot-cuts to CLECs is satisfactory.51 And, as demonstrated in Appendix H, the Bell companies’ hot-cuts performance is now excellent.

Migration of Mass-Market UNE-P Customers to CLEC Switches. Collectively, CLECs use their own switches to serve most of their customers. See Figure 3. Some CLECs, however, continue to rely primarily on the UNE Platform, which of course includes the switching element, to serve mass-market customers.52 These CLECs maintain that they remain dependent on ILEC switches to serve mass-market customers because they “cannot rationally invest in switches . . . until they have used UNE-P to build up a customer base.”53 But that assertion cannot be squared with the economics of switch deployment, and with the actual marketplace track record that other CLECs have established.

*The number of lines provided entirely over CLEC facilities and using CLEC switches is based on the number of E911 listings CLECs have obtained. Because the actual number of lines that CLECs are serving with their own switches is likely much higher, this method will, if anything, understate the percentage of all lines that CLECs are serving in whole or in part over facilities they have deployed themselves. **Verizon data do not include the former GTE territory.

It certainly is clear that some CLECs are not migrating mass-market UNE-Platform customers to their own facilities, and have no plans ever to do so. In New York, for example, AT&T and WorldCom together provide UNE-P service to well over one million residential customers54 – enough customers, in other words, to fill five to ten switches. Together, AT&T

51 See, e.g., New York Order ¶ 291; Order ¶ 159; Connecticut Order ¶ 13; Pennsylvania Order ¶ 86; Texas Order ¶ 256; Kansas/Oklahoma Order ¶ 199; Arkansas/Missouri Order ¶ 102. 52 In the Bell companies’ regions, approximately two-thirds of all platforms are used to serve residential customers, and the percentage is even higher in Verizon’s and SBC’s regions (80 percent and 70 percent, respectively). Most of the platforms used in the business sector appear to be used to serve small business customers, which the FCC previously has held are part of the same “mass market.” See, e.g., Bell Atlantic/NYNEX Merger Order ¶ 70. For example, nearly 25 percent of all platforms used to serve business customers are sold in BellSouth’s region, and half of those are sold to business customers with only 1-3 lines. 53 Ex Parte Letter from Robert W. Quinn, AT&T, to William F. Caton, FCC, CC Docket No. 01-347 (Mar. 1, 2002). 54 S.

and WorldCom also operate 28 local circuit switches in New York state.55 Yet these two carriers do not appear to have converted any residential customers in New York to their own switches.56 The experience has been no different in other states where AT&T and WorldCom have signed up large numbers of UNE-P customers. Other CLECs that have obtained UNE Platforms to serve mass-market customers also have conceded that they have no plans to convert these customers to their own switches, even after they have acquired a large customer base. They view UNE-P competition as an end in itself, rather than as a stepping stone to facilities-based competition.

Their position is based on business judgment, however, not on any economic imperatives. The UNE-P-forever CLECs have simply decided that there is more to be gained from relying on UNEs at TELRIC prices than from deploying their own facilities.

To begin with, many other CLECs are deploying switches to serve mass-market customers. Indeed, most of the CLECs that have deployed one or more switches, and that also serve mass-market customers, make little if any use of unbundled BOC switching. Leaving aside service provided over cable networks, at least nine CLECs in Bell company regions provide facilities-based service to 25,000 or more residential lines (based on their E911 listings). See Figure 4. Seven of the nine buy no UNE-P service at all. The remaining two represent only 3 percent of all facilities-based residential lines. But for one of these two CLECs, UNE Platforms represent only five percent of the residential lines that this carrier serves.

The same circuit switch in the same wire center can and routinely does serve both business and residential customers – ILECs use their switches in precisely that way, and many CLECs do too. For example, many of the cable operators that are now providing circuit- switched cable telephony are doing so using switches deployed originally by their CLEC affiliates to serve business customers.57 With switching, perhaps more so than with any other

network element, residential service can readily be added at the margin. And the vast majority of residential customers are now in reach of CLEC switches already in operation. CLEC switches are up and running in wire centers that serve 86 percent of all BOC access lines. And these same wire centers serve about 84 percent of BOC residential lines.

CLECs providing service to 25,000 or more facilities-based residential lines include: ALLTEL, Broadview, Cavalier Telephone, Intermedia, Knology, McLeodUSA, RCN, TDS, and TOTALink.

The only other justification that CLECs have given for their failure to convert mass- market customers from Platforms to their own switches relates to the cost of migrating the customer, not the cost of deploying or operating the switch itself. This does not establish that the UNE Platform is necessary for competition; to the contrary, it establishes that facilities-based competition will develop faster if CLECs do not build their customer base on UNE-P service at all.

As described above, the costs associated with collocation have fallen sharply since the UNE Remand Order, as the Commission has created numerous alternatives to traditional physical arrangements. The rates for hot cuts are set using TELRIC principles, and the BOCs’ hot-cut performance is closely monitored by state commissions. As a result, the transactional costs that CLECs seeking to use their own switch must incur are no different than the costs that any other network provider – including ILECs and cable companies – would need to incur to connect loops to its own switches.

But even assuming that hot-cut costs remain significant, substantial numbers of customers that seek phone service are entirely “new” customers in that they are first-time subscribers at the location at which they are requesting service. Wireline telephone companies add approximately six million subscriber lines each year.58 And, because people move, a significant fraction of existing customers terminate their current phone service and initiate new service at some other location every year.59 Together, these two groups define a large base of

58 See FCC Trends in Telephone Service, Aug. 2001 ed. at Table 8.1. 59 See, e.g., U.S. Census Bureau, Statistical Abstract of the United States: 2001 at 28 (Nov. 2001) (from 1999-2000, 15 percent of the U.S. population, or approximately 40 million people, changed residences).

II-19

customers who can be served without incurring the transaction costs associated with moving an established customer off of an ILEC switch and on to a CLEC alternative.

B. Packet Switches as Substitutes for Circuit Switches.

CLEC packet switches are already a very significant competitive alternative to ILEC circuit switches.

Packet switches substitute for circuit switches to the extent that traffic can be routed directly to a packet switch, without first being routed through a circuit switch. All forms of telecommunications traffic can now be transmitted and switched, end-to-end, in digital rather than analog format. And because packet switches are far more efficient in handling digital traffic than circuit switches, the economics of migrating traffic from circuit to packet switches have become incredibly compelling. Indeed, there already is far more data traffic than voice traffic, even on the circuit-switched public telephone network.

Of course, the CLEC packet switches in many cases also either are or are capable of being used to provide voice services. Long-distance carriers have been migrating their traffic to high-speed packet switches for several years. Having gained a robust, profitable entry point in high-speed data, local providers are now offering messaging and voice services over those networks too. The number of customers with local data links to packet switches is already large and growing very rapidly. And a large and growing share of these data links connect to packet switches that competing carriers – including CLECs, wireless carriers, and cable providers – own and operate.

Direct Customer Links to Packet Switches. At the time of the last UNE review, 98 percent of online households still relied on dial-up connections – and thus on ILEC circuit switches – for their data services.60 As discussed further in Section IV.C, however, nearly eight million residential users – or roughly 9 percent of online households – now have broadband cable or wireless data links instead, which bypass ILEC networks completely, and terminate directly on a competitive packet switch.61 If all eight million of these broadband users would otherwise be using dial-up connections, the packet switches used to provide these broadband services now displace at least 4 percent of all circuit-switched minutes of use, even assuming that the average data line is used only as much as the average voice line.62 The total would be far higher if one takes into account the fact that data calls generally last much longer than voice calls, and that data lines are therefore used much more, on average, than voice lines.63

See FCC Local Competition Report, Feb. 2002 ed. at Table 1 (as of June 2001, the ILECs served 174 million access lines, which has been declining in each of the last three years). 63 See, e.g., T.

The competitive impact is certainly at least double that, when one adds in the effect of data traffic from business customers, and takes into account the fact that high-speed data links carry far more traffic per user than low-speed voice links.64 Indeed, a recent study found that, for the first time, total hours spent on the Internet using high-speed connections have eclipsed the number of hours spent using dial-up connections.65 And broadband access usage is growing at more than 60 percent a year, while dial-up access usage is steadily declining.66

Cable and DSL providers (ILECs among them) are now adding new broadband data connections at a rate of some five million new connections a year.67 Cable supplies about two out of three of these connections.68 But even if they are using DSL services over ILEC loops, these customers no longer rely on the ILEC switch to route their data traffic: a splitter in the central office diverts data traffic directly to a packet-switched network before it ever reaches an ILEC circuit switch.69

Many business customers likewise rely on high-capacity connections of some kind – such as T-1 lines, or higher capacity loops – to provide direct connections between their LANs and their data carriers. As discussed in Sections III.B and IV.A, CLECs have deployed extensive fiber networks to connect business customers directly to packet-switched networks.70 In addition, there are a large number of carrier-agnostic wholesale fiber suppliers that operate fiber networks in most major metropolitan areas.71 And the economic viability of deploying fiber is increasing as the demand for greater bandwidth continues to grow at rapid rates.72

Wireless services provide additional links to packet-switched networks. Paging spectrum is now being used extensively for e-mail and instant messaging, and new devices to support such services are emerging rapidly.73 Cell phones, paging services (like the BlackBerry service), and personal digital assistants (PDAs) now provide wireless e-mail that is superior to dial-up wireline in that it is both mobile and “always on.”74 The Commission’s Sixth CMRS Report concluded that about 2.5 million customers, or about 2.3 percent of all mobile telephone subscribers, were using wireless web services at the end of 2000.75 A more recent analyst report found 6.7 million users of wireless data services.76 Wireless data has grown from a virtually non-existent market in 1998 to $250 million in 2001, and is expected to grow to $2 billion by 2003.77

An increasing number of business customers also are making direct connections to packet switches using a new generation of IP-Based PBXs.78 Although IP-PBX devices invariably provide connections (through a trunk) to the circuit-switched network, one of their key advantages is to send a great deal of voice traffic over private data networks such as a corporation’s local area network or wide area network. Because traffic remains on a private network, rather than going on to the public Internet, the corporation can configure the network to optimize quality to ensure high-level voice communications.79 IP-PBXs cost less to purchase and operate than traditional PBXs,80 and are more flexible in terms of adding new services.81

According to analyst studies, “17 percent of U.S. businesses began the implementation of IP LAN telephony in the year 2000,”82 and, as of year-end 2001, “[m]ore than 40% U.S. companies with 500 employees or more have begun conversion of phone systems to IP telephony.”83 Analysts predict that, within the next four years, more than 80 percent of all U.S. enterprises will adopt some form of VoIP.84 According to Frost & Sullivan, the North American IP-PBX market generated $375 million in 2000, and is expected to reach $4.8 billion by 2007.85

Packet Switching is Fully Competitive. The Commission has already concluded that CLECs stand on equal footing with ILECs in their ability to deploy and operate packet switches.86 Since the last UNE review, the installed base of CLECs’ packet switches has jumped from 860 to at least 1,700.87 More than 55 CLECs have deployed packet switches.88 See Appendix E. CLECs have deployed packet switches in more than 200 different cities. See id. In the top 100 MSAs, the average number of packet switches per MSA has grown by an average of nearly 150 percent since the last UNE review. See Table 11.

The two main kinds of packet switches used today are Frame Relay and ATM switches.89 One new packet-switching technology – Gigabit Ethernet – has recently been deployed, and is growing as an alternative to Frame Relay and ATM for very high-bandwidth applications.

The largest providers of both Frame Relay and ATM services are AT&T, WorldCom, and Sprint, which control more than two-thirds of the nationwide market for these services. See Figure 5.90 While the precise numbers of Frame Relay and ATM switches these carriers operate are unavailable, it is clear that they all operate vast nationwide Frame Relay and ATM networks. See Appendix I.91 As one analyst has noted, “[t]he Big 3 IXCs own the U.S. frame relay market, have scale economies and are best positioned to influence users and move the market.”92 Numerous other CLECs also provide ATM or Frame Relay service. See Appendix I.93 And while the Bell companies compete in the provision of these packet switching services as well, they have been significantly hampered by the fact that they cannot provide interLATA packet- switching services, despite the fact that customers typically desire a single carrier to provide both intraLATA and interLATA packet switching.94

89 See IDC Packet Switching Report at 1 & Figure 2 (frame relay and ATM services account for 96.4 percent of the packet-switching market). 90 See IDC Packet Switching Report at Figures 9, 31 (AT&T, WorldCom, and Sprint together accounted for 65.8 percent of revenues for ATM, and 68.4 percent of revenues for frame relay in 2000); Stratecast ATM/Frame Relay Report at 10 (“Tier 1 service providers continue to dominate the U.S. market, controlling over 70% of the market.”); id. at 17 (“In 2000, AT&T held the largest share of ATM service revenues, with a 36% share of [the] market; WorldCom and Sprint held the second and third leading position in the market with shares of 26% and 22%, respectively. As in the frame relay market, the RBOCs collectively represent a small share of the ATM services market.”). 91 AT&T Corp., AT&T ATM Service, Brochure, http://www.ipservices.att.com/brochures/atm.pdf (AT&T’s domestic Frame Relay and ATM network has over 620 Points of Presence (POP)); IDC Packet Switching Report at 137 (700+ POPs for WCOM); WorldCom, US Products, Data Networking, Frame Relay, http://www.worldcom.com/us/ products/datanetworking/framerelay/index.phtml (402 Frame Relay POPs); Sprint Corp., Sprint Business, Dedicated Access, Service and Support, http://www.sprintbiz.com/small_business/dedicated_ip/ (320 POPs). 92 Stratecast ATM/Frame Relay Report at 12. 93 The FCC already has recognized in the past that “it is precisely in the provision of services like frame relay that competition is most intense, and we acknowledge the sensitivity of the LECs’ position as they face increasing competition, especially regarding these services that are likely to be related to nonregulated and highly competitive services.” Policy and Rules Concerning Rates for Dominant Carriers, Memorandum Opinion and Order, 8 FCC Rcd 7474, ¶ 63 (1993). 94 As noted by industry analysts and CLECs alike, Bell companies are limited in their broadband offerings due to restrictions on the provision of interLATA services. See, e.g., Stratecast ATM/Frame Relay Report at 12 (“Thus far, the RBOCs have held a very small share of the frame relay market, primarily because they have only been allowed to II-24

The newest packet-switching technology being provided in metropolitan areas is Gigabit Ethernet.95 Competitive carriers also lead in the deployment of Gigabit Ethernet switches.96 As one analyst notes, “metro Ethernet services [are] being aggressively marketed by companies such as Yipes[,] Time Warner Telecom, XO, and Telseon.”97 These services are now available in central business districts of top tier markets, but also are being deployed more widely. Revenues for Gigabit Ethernet are still small – most estimates say under $100 million – but are expected to grow to as much as $4 billion by 2005.98 A recent survey of corporate users found that, although less than one percent of enterprise networks are using Gigabit Ethernet as their primary LAN transport today, nearly one-quarter expect to deploy Gigabit Ethernet within two years.99

Migration of Traffic to Packet-Switched Networks. Data traffic overtook voice traffic on the phone network in 1998. Since that time, the volume of data traffic has continued to grow much faster than voice.100 CLECs in particular earn almost half of all their revenues from data services – some $27 billion is the projection for 2002.101 Data services are the fastest growing source of CLEC revenue.102 See Figure 6 & Table 12.

However it is used, whether for pure “data” (like a spreadsheet) or for data traffic (like messaging) that may in fact compete with voice, the packet switch provides an entry point for CLECs into the provision of switching services in direct competition against ILEC circuit switches. Packet switches compete against circuit switches for all traffic that would otherwise move through a dial-up circuit-switched connection, but that now is conveyed instead to a packet switch directly. And, of course, these packet switches in many cases either are or are capable of being used to provide voice services along with the more traditional data services.

Residential and business customers alike now use e-mail and instant messaging (IM) as direct substitutes for many voice calls.103 A large and growing fraction of e-mail and IM traffic originates and/or terminates on competitive networks. And even when carried over ILEC networks, such traffic displaces significant usage-sensitive (e.g., per-minute or per-call) revenues that otherwise would be earned.

Kennard, Chairman, FCC, The Telecom Act at Three: Seeing the Face of the Future, address at the Comptel 1999 Annual Meeting and Trade Exposition, Atlanta, GA (Feb. 8, 1999) (“last year, for the first time, data traffic eclipsed voice traffic on phone lines.”); J.

There are now 900 million e-mail accounts in the U.S. and over 60 million IM users.104 It is estimated that consumers in the U.S. are sending approximately 3.2 billion e-mail messages105 and approximately 1 billion IM messages106 per day. If only 10 percent of these 4.2 billion daily e-mail and instant messages substitute for a voice call (of 5 minutes average duration), that is equivalent to about 750 billion minutes per year, or roughly one-third of all local traffic that passes through ILEC networks.107 And while estimates vary, consumer surveys find that the actual rate of voice substitution is considerably higher. See Table 13. E-mail and IM support voice services directly, too, particularly voice messaging services. Voice capabilities are already a standard feature of Instant Messaging.108 Yahoo!, MSN and AOL all offer voice messaging services over their instant-messaging networks.109

migrating voice traffic to high-speed packet switches for several years.111 Many CLECs have now begun to migrate their local voice traffic onto ATM and Frame Relay networks as well. See Table 14. All of the major packet switch manufacturers have developed voice capabilities for their packet switches.112 Growth for packet-based voice equipment outpaced all other telecom gear in first half of 2001.113 Analysts now agree that markets for both packet switches and voice- over-packet services will grow rapidly in the next few years.114

Cable operators, who have been offering cable telephony on their own circuit switches for several years, are now migrating to packet-switched alternatives as well. The upgrades that allow cable companies to offer cable modem services also make it possible for cable to provide high-quality digital telephone service with only a small incremental investment.115 Uniform industry standards for providing IP telephony over cable are now in place. The North American cable industry has developed and adopted the DOCSIS 1.1 standard.116 Since the adoption of

DOCSIS 1.1, the widespread deployment of cable telephony has been awaiting “the availability of cable modems based on version 1.1 of the Data Over Cable Service Interface Specification. DOCSIS 1.1,” which was first released in 1999.117 CableLabs began its certification program for compliant products in 2000; CableLabs certified the first DOCSIS 1.1 compliant cable modems in September 2001.118 Further tiers of certification are now nearing completion as well.119

Upgrading existing cable plant to provide IP telephony costs about $700 per line, or about 15 percent less than circuit-switched telephony.120 IP telephony also has lower operating costs (by at least 5 percent) than circuit-switched telephony, owing largely to the fact that “it can share a single infrastructure with data.”121 Cable operators are currently conducting trials of IP telephony. See Table 15. According to analysts, widespread commercial deployment of IP cable telephony (at least as a secondary line service) will begin in late 2002 or early 2003.122 Cable

There are strong incentives for CLECs and cable operators to migrate to packet switching.125 Packet switches serve the most dynamic, rapidly growing sector of the industry – the data sector. They are much more compact than circuit switches,126 and they are much cheaper to purchase and deploy.127

A new generation of “softswitch” packet switches is now accelerating all of these trends.128 They are fast enough to switch voice, data, video, and other forms of traffic; they are thus far more compact and efficient than the arrays of media-specific hardware that they can displace. Equipment manufacturers, CLECs, and industry analysts all agree that these new switches can serve as complete “replacements” for Class 5 switches. See Appendix J, Tables 1 & 2. Numerous CLECs have already deployed softswitches. See Appendix J, Table 3. The Yankee Group expects worldwide sales of softswitches to rise from $16 million in 1999 to $824 million in 2003.129 Frost and Sullivan predicts that “providers will invest more than $39 billion in softswitch technology by 2006 and will realize $85 billion for services delivered using the technology that year.”130

C. Wireless Switches as Substitutes for Circuit Switches.

Wireless switches substitute for wireline switches at the margin, in much the same way as packet switches do. The marginal buyer of wireline service is the residential buyer of second-

line service. And as “margins” go, this is a big one: approximately 26 percent of U.S. residential customers buy second-line service from a wireline phone company.131

As of February 2002, there were an estimated 130 million wireless subscribers in the United States – up from 34 million at the end of 1995132 – as compared to the approximately 190 million users of switched landline telephone service.133 Two in five Americans – with all adults and children included in that count – have a mobile phone. 134 Some twenty million new subscribers are being added annually.135 Wireless carriers are adding subscribers much faster than their wireline counterparts – in percentage terms, and in absolute terms, too.136 See Figure 7.

All of this wireless traffic is switched traffic. Wireless carriers other than those affiliated with Bell companies have deployed a total of more than 950 circuit switches nationwide. See Appendix F.137 Many of the switches that wireless carriers are using are indeed the same switch types that CLECs are using – for example, the Lucent 5ESS, Nortel DMS 100, and Ericsson AXE-10.138

At the end of 2001, wireless calls already accounted for an estimated 12 percent of all U.S. phone calls.139 There were approximately 200 billion billable minutes of wireless use in the first half of 2001, up 77 percent from June 2000, and up 34 percent from December 2000.140 Wireless networks now switch at least one-quarter of the amount of traffic as wireline networks.141 And wireless minutes of traffic are growing at over 60 percent per year, while landline minutes are growing at “low single digits.”142

A second very large margin for which wireless switches compete is switched access traffic. In addition to completing local calls, local switches serve the second function of providing switched access to long-distance networks. Local access revenues represent approximately 14 percent of all local service revenues;143 long-distance calling minutes (i.e., access minutes) represent about one-quarter of all switched minutes on local plant.144 Wireless plant certainly competes directly against wireline plant here, too.

There are 130 million wireless subscribers and the average subscriber uses 339 minutes per month (4,068 per year) on her wireless phone, resulting in approximately 529 billion originating and terminating wireless minutes per year.

At least twenty million wireless customers (and counting) have plans that do not charge extra for long-distance.145 The average price of a wireless long distance call is comparable to the average price of a long distance call made via wireline.146 Many wireless carriers heavily market the “free long-distance” aspects of their service. Analysts report that “[t]he bundling of long distance calling at price points that are perceived as ‘nearly free’ to consumers is already making wireless long distance calling a more cost-effective alternative to wireline long distance calling to many wireless consumers.”147 Thus, “wireless continues to take share from wireline local and long distance usage.”148 AT&T recently noted that its wireline long-distance minutes of use were down about 10 percent, while its wholesale wireless long-distance traffic was running up about 35 percent.149

While wireless-wireline competition starts at the margin, it by no means ends there. Wireless is increasingly competitive with core primary-line wireline services. When the comparison is made between equivalent bundles of service, it is clear that wireless services are now price-competitive with wireline. Almost all wireline CLECs focus on selling bundles of service – not just basic access, but bundled long-distance and additional features as well.150 And so do almost all wireless carriers. And so do most of the ILECs themselves. Regulation does require ILECs to offer unadorned, basic, local service at a very low price to all residential customers. But the vast majority of wireline customers buy much more – long-distance service, to begin with, which generates additional local-carrier revenues by way of access charges. And often, as well, other value-added features like call waiting, voice mail, and caller ID. A November 2001 Gartner Dataquest study concludes that wireless calling prices are already “competitive with, and in some case better than, wireline calling rates.”151

Wireless prices continue to decline rapidly – by as much as 10 to 20 percent a year in recent years.152 While the length of the average wireless user’s local call has increased, the average local monthly wireless bill has fallen from $97 in 1987 to $45 in 2001.153 Analyst IDC attributes the dramatic growth in wireless usage, particularly in home and business locations that provide wireline access too, primarily to the fact “that wireless service pricing is rapidly approaching wireline service pricing.”154 At prices now in effect, wireless “is viewed as a cost- effective and compelling alternative to wireline.”155 Numerous analysts have reached the same conclusion.156

The Commission itself has agreed with this assessment in its July 2001 Sixth CMRS Report. It found that the wireless phone has “become a mass-market consumer device,” that most wireless customers use their phones “primarily for personal calls,” and that three in ten wireless users would prefer to give up their landline phone, if forced to choose, and that number rises to almost one in two among younger users.157 The Commission’s Report went on to discuss wireless services that are specifically being marketed as alternatives to wireline service.158 Citing a Yankee Group survey, the report also found that at a quite sizable number of consumers – about 3 percent of wireless subscribers – have now abandoned wireline – in favor of wireless – entirely, “rely[ing] on their wireless phone as their only phone.”159 A more recent USA Today/CNN/Gallup poll found that 18 percent of cell phone users “use cell phones as their primary phones.”160

III. INTEROFFICE TRANSPORT

The interoffice transport UNE comprises links between ILECs’ and requesting carriers’ wire centers or switches, and between ILEC switches.1 A “wire center” is an end office where local loops terminate at an ILEC switch.2 Interoffice transport does not include transport between an ILEC or CLEC switch and a customer.

The provision of interoffice transport is now highly competitive. The first competitors entered urban markets in 1985, and they have been laying competitive fiber optic networks ever since. The Commission first directed ILECs to provide collocation to competitive access providers in 1992.3 Today, competitors have established fiber connections in a large fraction of BOC wire centers, which serve a significant percentage of BOC access lines. Many of the competitive transport facilities that CLECs have deployed are used to provide special access services; competitors now earn between 28 and 39 percent of all special access revenues.

As detailed below, it clearly is economical for competitors to serve an even larger number of wire centers with their networks than they currently do. With each additional mile of competitive fiber that gets deployed, the marginal cost of extending the network to reach an additional wire center gets lower. And the rise of the Internet has made it all the more attractive for CLECs to extend their fiber networks to ILEC end offices. Data connections generate a lot more traffic than voice calls do; the total volume of data traffic overtook voice traffic in 1998.4

A. Fiber-Based Collocation.

CLECs that provide competitive transport typically do so by collocating their own transmission equipment in an ILEC central office and connecting that equipment to their own fiber-optic network. This “fiber-based collocation” supplies the simplest and most unambiguous indicator of the extent of competition in the transport market, albeit a very conservative one that sharply underestimates the full extent of competition.

With few exceptions, competitively supplied transport begins in a CLEC collocation cage.5 At the time of the last UNE review, the data required to determine where CLECs had

1 See 47 C.F.R. § 51.319(d)(1)(i) (defining dedicated transport as “transmission facilities . . . between wire centers owned by incumbent LECs or requesting telecommunications carriers, or between switches owned by incumbent LECs or requesting telecommunications carriers.”); id. § 51.319(d)(1)(iii) (defining shared transport as “transmission facilities . . . between end office switches, between end office switches and tandem switches, and between tandem switches, in the incumbent LEC network.”). 2 See Newton’s Telecom Dictionary 995 (16th ed. 2000). Wire centers vary widely in size, from fewer than 500 lines in rural areas, to over 300,000 in the most densely populated urban areas. 3 See Expanded Interconnection with Local Telephone Company Facilities, Report and Order and Notice of Proposed Rulemaking, 7 FCC Rcd 7369 (1992). 4 See Section II, note 100. 5 See, e.g., W.T. Scott, et al., ING Baring Furman Selz LLC, Investext Rpt. No. 2787890, Telecommunications/Fiber Vs. Fiberless (Sept. 30, 1998) (quoting then-WinStar CEO, Bill Rouhana: “The fundamental underpinning of the strategy of most fiber-based companies in the industry today is that we will build to a central office, and we will co-locate with a regional bell operating company.”); id. (quoting Allegiance Telecom CEO III-1

obtained fiber-based collocation was not available.6 It is today. The Commission’s August 1999 Pricing Flexibility Order makes the presence of fiber-based collocation the trigger for pricing relief for special access services, and ILECs have therefore begun to compile such data systematically.7

As shown in Table 1, fiber-based collocation is now widespread. As of year-end 2001, one or more CLECs had obtained fiber-based collocation in 13 percent of the wire centers served by the Bell companies, which contain 54 percent of the business lines and 44 percent of all access lines served by the Bell companies. See Table 1. There also are multiple CLECs with fiber-based collocation in a large number of BOC wire centers, which contain a significant share of BOC access lines. See id.

In large metropolitan areas the totals are even higher. For example, in the 25 largest MSAs served by each BOC, an average of one or more CLECs had obtained fiber-based collocation in 35 percent of the wire centers served by the Bell company in those MSAs (containing 61 percent of all access lines within those MSAs). See Table 2. And, again, there

are multiple CLECs with fiber-based collocation in a large number of BOC wire centers in the largest MSAs, which contain a significant percentage of BOC access lines. See id.

It is clearly economical for competitors to deploy fiber in an even larger share of wire centers than they currently serve. Some 30 percent of all wire centers contain 5,000 or more business lines, and those wire centers contain 84 percent of all business lines.8 In those quantities, independent analysts have found that voice lines readily generate traffic in volumes sufficient to justify competitive fiber-optic transport.9 And the actual experience of CLECs in the marketplace bears this out.

As shown in Table 3, one or more CLECs has obtained fiber-based collocation in nearly half of BOC wire centers with 5,000 or more business lines. See Table 3. And in wire centers with larger numbers of business lines, it is even more likely that at least one CLEC has obtained fiber-based collocation in that wire center. See id.

(“As might be expected, it is apparent that businesses residing with larger central offices spend up to one-third more on average per business per month than those businesses in smaller central offices.”).

A fiber-based collocation test for the availability of competitive transport certainly provides a reliable indicator of which ILEC wire centers are served by competing fiber networks. It is worth emphasizing, however, that this test takes no account of the considerable amount of traffic that now bypasses ILEC wire centers completely. As one appellate court has noted, the fiber-based collocation metric “fails to account for the presence of competitors that . . . have wholly bypassed incumbent LEC facilities.”10

This is all the more true because the ILEC wire center is no longer the only – or even the principal – point of traffic concentration. So if it is economical for a CLEC to run competitive fiber to reach an ILEC wire center, it is often economical to extend the fiber, directly to datacom hotels, large business customers, data ISPs, wireless carriers, cable headends, and countless other points of traffic concentration.11

Many private customers also now generate sufficient quantities of traffic to justify their own fiber optic connections. As discussed in Section IV.A, there are now direct CLEC fiber connections to tens of thousands of buildings in the U.S. – buildings that house a substantial fraction of all business customers.

CLEC networks also converge today at many other points of high traffic concentration, including interexchange carrier POPs and Network Access Points (NAPs). “Collocation hotels” – like those operated by Switch & Data, Cable & Wireless (formerly Exodus Communications), Global Switch, and Metro Nexus – create additional points of traffic concentration. These centers provide large (typically 10,000-50,000 square foot), high-security facilities to house servers, data storage equipment, and the network interface equipment used by telecom carriers and ISPs.12 They give multiple CLECs and IXCs points at which to station their equipment and interconnect their networks.13 Many of them are located right on the doorstep of existing ILEC wire centers.14 In terms of how much traffic they originate and terminate, these facilities are as large as – and often much larger than – ILEC wire centers.15 Data traffic at these centers is now

10 WorldCom v. FCC, 238 F.3d. 440, 462 (D.C. Cir. 2001) (quoting Pricing Flexibility Order ¶ 95). This framework also is conservative because it examines only fiber-based collocation, even though competitive carriers have obtained thousands of collocation arrangements that, although not fiber based today, could easily be modified to connect to third-party fiber. 11 See, e.g., Wall Street Transcript Corp. Interview, John Peters – Sigma Networks (John Peters, CEO, Sigma Networks: “[W]e’ve targeted our network to address the interconnection needs principally between all of the major sources and links of data traffic in the metro. We’ve targeted the major carrier hotels, the major data centers, the Internet backbone connection points ‘the MAEs, the PAIXs’ and the broadband backbone networks.”). 12 See D. Culver, Construction Boom for Colocation. 13 See R. Duran, Checking into Telecom Hotels, Bus. Xpansion J. (Feb. 2001), http://www.bxjonline.com/ issues/feb2001/telecom_hotels.asp. 14 See D. Culver, Construction Boom for Colocation (collocation hotels provide “high-security facilities operated by independent companies that put telecom gear as close as possible to incumbent central offices without actually being there.”). 15 See, e.g., R.J. Sherman, Janney Montgomery Scott, Investext Rpt No. 2121566, Exodus Communications – Company Report at *2 (Apr. 4, 2000) (“It is estimated that 50% of all Internet traffic flows from Exodus’ data centers.”); F. Billimoria, et al., Hambrecht and Quist Inc., Investext Rpt No. 2724275, Exodus Communications – Company Report at *2 (Nov. 20, 1998) (“The company estimates that 10-12% of traffic that is carried over the Internet

growing at 100 percent a year, “and will consume 40% of total metro bandwidth by 2005.”16 Datacom hotels “tend to be concentrated in the top 15 Tier One metros, which account for 80% of demand.”17 Nonetheless, today there are alternative collocation providers in virtually all major metropolitan areas throughout the country. See Appendix G.

That there are many different points of traffic concentration is competitively significant in two important respects. First, high-traffic-volume nodes provide network economies of scale to many smaller competitors, by consolidating their traffic at a single physical location. To obtain competitive transport, a CLEC no longer has to grow organically; it can, instead, just locate itself in the right building. Second, the major competitive fiber-optic providers in an area are all very likely to route their networks to these locations – thus effectively providing connection to all points served by all the competing networks combined. The CLECs themselves can hand off traffic to each other, or an intermediary can bundle and resell their services as a single, integrated competitive service. Thus, while any single competitive fiber network may serve only a select number of point-to-point routes, that carrier will have access to the point-to- point networks of other competing carriers as well. The universe of total competitive fiber – not the point-to-point routes of any individual competitor – defines the geographic areas within which competitive transport facilities are now available.

Three years ago, the Commission downplayed the competitive significance of competitive transport on the ground that CLECs “require dedicated transport facilities that are more extensive than those that are currently deployed along the point-to-point routes.”18 The Commission stated that, “[w]ithout access to the incumbent’s ubiquitous transport facilities, competitive LECs are faced with the delays and costs of deploying their own transport facilities to meet the demand” or “must utilize a patchwork of competitive alternatives, where available, to collect and route traffic to the required destination.”19 Whatever the merits to that concern three years ago, the market itself has overtaken it today. Competitive transport networks now overlap and converge. Today, CLECs routinely seek out competitive suppliers of fiber; the supposed administrative costs of building patchwork solutions have been readily overcome.

Marketplace experience firmly establishes that carriers will seek out competitive suppliers of fiber, even where it means relying on a patchwork of different networks, rather than the ubiquitous facilities of an ILEC.20 This is precisely the way the competitive access business began, with the large interexchange carriers purchasing competitive fiber in just a single goes through an EXDS data center. They also noted that during peak periods, they are transmitting sustained levels of 2.4 gigabits/sec of traffic across the Internet, which we believe makes EXDS the 3rd or 4th largest generator of traffic.”). 16 Lehman/McKinsey MAN Report at 6. 17 Id. at 6-7. 18 UNE Remand Order ¶ 346. 19 Id. 20 See, e.g., Joint Comments of Allegiance Telecom, Inc. and Focal Communications Corporation at 5, Implementation of the Local Competition Provisions of the Telecommunications Act of 1996, CC Docket No. 96-98 (FCC filed June 11, 2001) (“Where it is available, Allegiance and Focal purchase transport and fiber from third parties.”).

location, at first, and slowly expanding from there.21 AT&T and WorldCom found the business so compelling, that they spent $25 billion to acquire their two largest suppliers.22 Today, as discussed in more detail below, CLECs are purchasing as much fiber as they can from wholesale suppliers, even though these suppliers do not necessarily offer fiber everywhere. These suppliers obviously wouldn’t even be in business if CLECs were willing to purchase transport only from suppliers who offered them ubiquitous connectivity.

B. CLEC Fiber.

At the time of the UNE Remand Order, the Commission found that, based on market conditions at the end of 1998, “competitive LECs have deployed transport facilities along selected point-to-point routes, primarily in dense market areas.”23

Since that time there has been a further, sharp increase in the availability of competitive alternatives to ILEC interoffice transport facilities.24 At the time of the UNE Remand proceedings, for example, CLEC fiber networks spanned approximately 100,000 route miles (both local and long-haul).25 Today, CLEC networks consist of at least 184,000 route miles of fiber (both local and long-haul).26 While many CLECs do not publicly report how many purely local route miles of fiber they operate, information from CLECs that do release such totals confirms that the majority of this fiber is local.27

While CLECs have significantly expanded their own local fiber networks, there also has been a rapid increase in local fiber supplied by “carrier-agnostic” wholesale suppliers. These companies have invested well over $1 billion in deploying local fiber networks that they sell or lease to other carriers. As a result, for a growing number of CLECs, the fiber provided by these wholesale suppliers satisfies a large part of their demand for interoffice transport.

21 See Section III.B. 22 See AT&T News Release, AT&T Completes TCG Merger (July 23, 1998); WorldCom Press Release, WorldCom, Inc. and MFS Announce Merger to Form Premier Business Communications Company (Aug. 26, 1996). 23 UNE Remand Order ¶ 333. 24 This competitive transport is available to wireless carriers, just as it is to CLECs. Moreover, wireless base stations and switches (MTSOs) typically handle sufficient volumes of traffic to justify new fiber connections. 25 See NPRG CLEC Report 2000, 12th ed., Ch. 6 at Table 5 (restated 1998 route miles). As described in the following note, the latest NPRG report excludes fiber for competitive Independent Operating Companies, utility CLECs, data providers, and Gig-E providers. To make an apples-to-apples comparison with the 2001 totals, we have removed from the 1998 totals the fiber for carriers that NPRG has placed in one of these categories. 26 NPRG CLEC Report 2002, 15th ed., Ch. 2 at Table 7; Ch. 4. This is a highly conservative estimate. It does not include 117,000 route-miles of fiber that NPRG lists for competitive Independent Operating Companies, utility CLECs, data providers, or Gig-E providers. Moreover, the total miles for 2001 have been adjusted downward to address the concerns that CLECs raised in the Special Access proceeding in April of 2001 (CC Docket No. 96-98). 27 For example, of the 33 CLECs for which NPRG provides fiber-route miles, we have found only four examples (Adelphia, McLeod, Time Warner Telecom, and XO) where, based on CLECs’ own public disclosures, the total route miles reported by NPRG appear to include significant amounts of long-haul fiber. At the same time, the total route miles reported by NPRG are lower than local-only route-mile totals provided by at least two CLECs (AT&T and Cablevision) and do not include any fiber route miles for WorldCom, which is one of the two largest CLECs.

III-6

The first competitive transport services involved the provision of “access” between large business customers and interexchange carriers. New York authorized interoffice competition in 1985, and that year Teleport built a fiber-optic network in lower Manhattan, to provide special access service to business customers, where the most concentrated wire centers in the nation reside. Sixteen other states had followed New York’s lead by August 1986.28 Institutional Communications Company (ICC), the second major CAP, was formed in 1986 in Washington, D.C.; it is now a part of MCI/WorldCom’s MFS.29 In 1987, Chicago Fiber Optic (soon to be MFS) began building a network to provide special access in downtown Chicago.30 By 1990, CLECs had deployed 20 networks in 15 cities.31 By 1995, 29 CAPs had deployed fiber-optic networks in approximately 100 cities, consisting of more than 21,000 route miles of fiber.32

Since the last UNE review, the number of “operational” and “on-net” CLEC networks in the 150 largest MSAs – which contain nearly 70 percent of the U.S. population33 – has grown from approximately 1,100 to nearly 1,800. See Appendix K.34 During this period, the average number of CLEC networks in the 150 largest MSAs grew by more than 60 percent. See Table 4. Today, 91 of the top 100 MSAs are served by at least three CLEC networks; 77 are served by at least seven, 59 are served by at least 10. See Appendix K. As these data make clear, CLEC fiber is by no means limited to dense urban areas. CLECs also have deployed fiber far outside of urban areas to reach large business customers in suburban and rural areas.35

Fairbank, RAIL SWITCH; Union Pacific Develops High-Tech Subsidiary, Dallas Morning News at 1D (Oct. 18, 2000) (Ekanet, a subsidiary of the Union Pacific railroad, “aims to provide services to underserved, primarily rural, markets west of the Mississippi River”); Fujitsu Equipment Drives New Fiber Network Serving Northwestern South Dakota, Bus. Wire (Nov. 6, 2000) (South Dakota Network “is now offering advanced telecommunications services to customers in rural northwest South Dakota through a 600-mile fiber-optic network”).

III-7

Finally, there are new technologies on the near horizon that would enable additional fiber to be deployed without digging up city streets, which “could cut the time and cost of fiber installation in half.”36 For example, “CityNet Telecommunications aims to revolutionize the rollout of broadband services in cities by dispatching tiny robots to lay fiber-optic cables in sewer pipes.”37 The company already has agreements to deploy fiber in nine major cities (Houston, Pittsburgh, Dallas, Scottsdale, Indianapolis, Fort Worth, Omaha, San Antonio, and Albuquerque),38 and is in talks with dozens of other cities. In April 2001, the company announced that it had secured $275 million in a new round of financing, which “underscores the novelty and promise of the . . . company’s business.”39

Many of the competitive transport facilities that CLECs have deployed are used to provide special access services. Special access revenues constitute a very large share of all interoffice transport revenues. Moreover, these revenues are highly concentrated in a relatively small number of wire centers,40 making them an easy target for CLECs to serve with their own facilities. The Commission has found that “the revenues of competitive LECs come primarily from special access and local private line services.”41 CLECs now account for between 28 and 39 percent of all special access revenue, which is significantly larger than their share of the local exchange market as a whole.42

C. Wholesale Suppliers of Local Fiber.

In the past few years, there has been a dramatic increase in fiber supplied by alternative wholesale suppliers, which typically sell or lease dark fiber to other carriers, but do not

themselves engage in the provision of telecommunications services. See Table 5.43 Five of these alternative fiber suppliers have formed an industry coalition – the Coalition of Competitive Fiber Providers – which states that its members’ business plans involve the “provision of competitive fiber-based transport services and dark fiber to competitive local exchange carriers . . . collocated in ILEC central offices.”44 The Coalition claims that its “members together represent a total capital investment of approximately $1 billion.”45 According to analysts, metropolitan fiber suppliers have raised about $2 billion in capital since the third quarter of 2000, and are still “some of the few getting capital.”46 These companies have recently raised significant additional funding through debt and vendor financing.47 According to consulting firms Cambridge Strategic Management Partners and McKinsey & Co., “[t]he market for reselling . . . dark fiber to ISPs and telecom carriers is projected to grow from about $2 billion today to about $10 billion by 2006.”48

Just like CLECs, alternative wholesale suppliers of fiber connect end users to their fiber rings, which in turn connect to interexchange carrier POPs and ILEC central offices.49 Because

these alternative suppliers are “carrier agnostic,” they can use their networks to serve multiple carriers at once, significantly improving the economics of deploying fiber.50 For a growing number of CLECs, the fiber provided by these wholesale suppliers satisfies a large part of their demand for last-mile local connectivity and interoffice transport.51 In fact, these alternative suppliers’ networks are so expansive that even ILECs have begun purchasing fiber from them.52

In addition to this new breed of wholesale fiber suppliers, many of the nation’s utility companies are now supplying local fiber to CLECs. See Table 6. Utility companies control a significant portion of the nation’s fiber infrastructure – as much as 35 percent according to one source.53 These companies have the advantage of being able to deploy fiber using their existing infrastructure. As one analyst notes, “If a company already has wires or pipes in the ground, the cost of entry is comparatively low.”54 Another analyst notes that “roughly half of the new metro networks being built in the United States are being constructed by utilities.”55

Finally, several of nation’s largest operators of long-haul fiber networks have recently constructed metropolitan fiber networks. See Table 7. These carriers have sold dark fiber on their long-haul networks to CLECs for many years, and have now begun leasing dark fiber on

IV. LOCAL LOOPS

As the Commission has recognized, loops come in a wide range of capacities. The availability of competitive substitutes varies accordingly. In addition, the availability of substitutes varies significantly among geographic markets.

A. High-Capacity Loops.

The FCC defines a “high-capacity loop” as a loop from a customer to an ILEC central office that is capable of supporting a service at DS-1 speeds (i.e., 1.544 Mbps) or higher.1 A DS- 1 facility consists of 24 individual 64 kbps DS-0 circuits, the bandwidth normally used for a single voice channel.2 The individual circuits on DS-1 loops and higher can, however, be configured to provide any mix of voice and data services.3 High-capacity loops are almost always provided to medium or large business customers.

As described in Section III, competitive access providers began deploying fiber networks immediately after the Bell break up, to provide interoffice transport between the ILECs’ Class 5 switches and the Interexchange Carriers’ Class 4 counterparts. CLECs then began extending their fiber between ILEC central offices. They then moved beyond carrier-to-carrier services, extending their fiber to provide a full range of high-capacity local services to large private customers.

The economics of supplying high-capacity loops are exactly the same in the service of large customers as they are in the service of carriers. Either way, high traffic volumes between specific pairs of points justify the deployment of new fiber. And the further the competitive fiber network runs, the more economical it becomes to add customers along the existing route, and to extend the fiber further still.

1. CLEC Fiber as a Substitute for High-Capacity ILEC Loops.

Collectively, CLECs use their own last-mile facilities to serve the vast majority of their large business customers. CLECs serve no fewer than 13 million business lines and likely closer to 20 million business lines using their own switches, yet they have obtained only about 1.5 million stand-alone unbundled loops to serve business customers. See Table 1.4

1 47 C.F.R. § 51.319(a)(1) (“The local loop network element is defined as a transmission facility between a distribution frame (or its equivalent) in an incumbent LEC central office and the loop demarcation point at an end-user customer premises. . . . The local loop includes, but is not limited to, DS1, DS3, fiber, and other high capacity loops.”). 2 See Whatis.com, Digital Signal X, http://whatis.techtarget.com/definition/0,,sid9_gci212004,00.html (DS0 has “a transmission rate of 64 kbps, the bandwidth normally used for one telephone voice channel.” DS1 “is 24 DS0 (64 kbps) signals.”). 3 See Qwest, Data, DS1, http://www.qwest.com/pcat/small_business/product/1,1354,140_3_2,00.html (“Each DS-1 Service comprises 24 channels that may be assigned in a wide variety of ways to support switched access, local exchange service, low-speed data, voice grade communications, audio services and digital data services.”). 4 This calculation is a conservative estimate of the number of larger business customers that CLECs serve over their own loop facilities because many of the stand-alone unbundled loops that CLECs have obtained are likely used for smaller business customers.

IV-1

Table 1. CLEC Business Lines Provided Over CLEC-Owned Last-Mile Facilities Total Facilities-Based Unbundled Business Lines Provided CLEC Business Lines Business Loops* Over CLECs’ Own Loops Verizon** 3.7 – 6.8 million 467,000 3.3 – 6.3 million SBC*** 4.5 – 7.4 million 765,000 3.7 – 6.7 million BellSouth 1.8 – 3.2 million 229,000 1.6 – 3.0 million Qwest 2.9 million 63,000 2.8 million Total 13 – 20 million 1.5 million 11 – 19 million *ILECs do not maintain data on whether an unbundled loop is used to serve a business or residential customer. We have developed the estimate of unbundled loops used to serve business customers as follows: CLECs provide at least 3 million residential lines over facilities they have deployed themselves, and approximately 1.5 million of these lines are provided over cable telephony networks. We assume the remaining 1.5 million residential lines are provided using unbundled loops, and that all other stand-alone unbundled loops provided by ILECs to CLECs are used to serve business customers. **Total for Verizon does not include the former GTE service area. ***Total for SBC does not include Connecticut.

Any count of “lines,” however, severely underestimates the CLECs’ actual share of the business market. A high-capacity line represents more market share than a low-capacity line, and CLECs tilt their businesses strongly toward the former. While CLECs as a whole supply a total of between 13 and 20 million business lines using their own switches, 12 of the CLECs included in that total supply over 156 million voice-grade-equivalent circuits.5 AT&T’s Business division reports serving 2.7 million “local voice lines” but “over 30M DS0 equivalents.”6

Based on the highly conservative count of lines that CLECs provide over their own facilities, the CLECs now supply at least 20 percent and likely closer to 28 percent of all business lines nationwide. See Figure 1. That percentage is undoubtedly much higher in major metropolitan areas where the largest business customers are concentrated.7 The FCC’s own data confirm that the CLECs’ share of large business customers is considerably higher than their share of the overall business market.8

Dorman, President, AT&T, Presentation Before the Lehman Brothers T3 Telecom, Trends & Technology Conference (Dec. 6, 2001). 7 See, e.g., UNE Remand Order ¶ 291, n.573 (“The local competition that has developed has focused on larger business customers in large cities, not on residential or small business customers.”); FCC, Biennial Regulatory Review 2000 – Staff Report, App. IV, Pt. 54, 15 FCC Rcd 21089, 21266 (2000) (“Competition for business customers in metropolitan areas has, in general, developed more rapidly than competition for residential customers or customers in rural areas.”); FCC Local Competition Report, Dec. 1998 ed. at 2 (“Facilities-based CLECs appear to have concentrated in more urbanized areas.”). 8 According to FCC’s most recent Local Competition Report, CLECs’ share of the “Medium to Large Business Market” was nearly four times their share of the “residential and small business market.” FCC Local Competition Report, Feb. 2002 ed. at Table 2.

These totals also are consistent with the significant inroads that CLECs have made into the special access market. The provision of special access service typically involves both a high- capacity loop and, as discussed in Section III, interoffice transport. Because special access revenues are highly concentrated among a relatively small number of wire centers, CLECs have been able precisely to target their facilities to serve this lucrative market. Today, CLECs account for between 28 and 39 percent of all special access revenue.9

It does not take a very far-flung network to reach a very significant number of high- volume customers. It has been estimated that, in a typical Tier-One MSA, just 200 to 300 multi- tenant units – out of an average of 15,000 or more multi-tenant units in such MSAs – generate an estimated 80 percent of the data revenues generated in those MSAs.10 And the top 15 MSAs generate almost 80 percent of the nation’s data traffic.11 Just four MSAs – New York, San Francisco, Washington, D.C., and Los Angeles – generate some 40 percent.12

Most CLECs do not report how many buildings their fiber networks serve.13 Public data are available for only about 20 CLECs;14 as of year-end 2001 this small subset of CLECs

9 See Appendix L. 10 See Lehman/McKinsey MAN Report at 8 (emphasis added) (“enterprise traffic is currently very concentrated, as in a typical Tier One MSA, 200 to 300 MTUs (of more than 15,000) constitute 80% of data revenues.”). 11 See id. at Figure 3. 12 See id. at 6-7. 13 See, e.g., CSFB 3Q01 CLEC Vital Signs Review at Exh. 16 (total buildings data for 8 of the 14 profiled CLECs were not available); J. Atkin & D. Coleman, Dain Rauscher Wessels, City Light: An Investor’s Guide to Metropolitan Optical Services at 11 (Mar. 22, 2001) (“Few carriers release detailed data on their fiber networks.”). 14 By comparison, there are at least 110 CLECs as well as numerous wholesale fiber suppliers that currently operate metropolitan networks. See NPRG CLEC Report 2002, 15th ed., Ch. 6; Section III.C.

IV-3

operated networks that served approximately 330,000 buildings.15 This figure, however, includes “off-net” buildings – buildings served in part using facilities leased or resold from another competing carrier or an ILEC. CLECs have estimated that the number of unique office buildings served entirely by their fiber networks is roughly 30,000 nationwide.16

Given that CLECs route them to large commercial office buildings and other points of high traffic concentration, CLEC networks are clearly capable of serving far more high-capacity business lines than they currently do. Once they extend their network to serve one customer in a building, CLECs can vie for the business of all the other tenants, too. And CLEC fiber networks are now so extensive that they readily can be – and routinely are – extended as needed to pick up additional traffic from new customers in adjacent buildings, or down the block, and on outward, incrementally, from there. Once an initial fiber ring is deployed in a metropolitan area, extending that fiber incrementally to new customers is comparatively cheap.17 When they deploy fiber, carriers invariably deploy far more capacity than they can use immediately, to facilitate precisely this process of incremental future development.18 And the bigger the network grows, the more economical it becomes to extend it to reach additional, lower-traffic, lower- revenue customers.

Rapidly rising traffic volumes make the economics of deploying competitive fiber increasingly attractive. Traffic volumes from “large enterprises” – which generate half of the traffic in metropolitan markets19 – are growing at an estimated 40 percent a year.20 Data traffic for small and mid-size enterprises is growing at an estimated 60 to 70 percent a year.21 As traffic volumes rise, competitive fiber networks quickly move from merely “competitive” to markedly

15 NPRG CLEC Report 2002, 15th ed., Ch. 4 at Table 19. This is a highly conservative estimate. It excludes not only the buildings served by literally dozens of CLECs, but also does not include the 27,000 additional buildings NPRG reports for competitive Independent Operating Companies, utility CLECs, data providers, Gig-E providers, fiber layers, and other providers. See id. Moreover, the total buildings have been adjusted downward to address the concerns that CLECs raised in the Special Access proceeding in April of 2001 (CC Docket No. 96-98). 16 See Joint Comments of Allegiance Telecom, Inc. and Focal Communications Corporation at 25, Implementation of the Local Competition Provisions of the Telecommunications Act of 1996, CC Docket No. 96-98 (FCC filed June 11, 2001); Comments of WorldCom, Inc. at 7, Implementation of the Local Competition Provisions of the Telecommunications Act of 1996, CC Docket No. 96-98 (FCC filed June 11, 2001). 17 As the FCC has noted, “[t]he technological advances in fiber and electronics have made expansion of transport capacity relatively inexpensive. Once a competitor has infrastructure in place, the marginal cost of adding customers is not significant, and competitors are not likely to lack sufficient capacity for an extended period.” Brief of FCC, Respondent, at 36, MCI WorldCom v. FCC, No. 99-1395 et al. (D.C. Cir. filed Nov. 30, 2000). 18 See B. Gain & D.

superior. Next-generation technologies (SONET-lite, Metro DWDM and Gigabit Ethernet) are estimated to be 30 to 70 percent more cost-efficient than legacy networks.22 Network capacities are rarely if ever an issue; year by year it gets easier and cheaper to boost the capacity of existing fiber by upgrading the electronics that “light” it. Data-carrying capacities are indeed doubling about every 9-10 months.23

In these circumstances, it is not surprising to find that CLECs and wholesale fiber suppliers widely tout their willingness to extend their networks to pick up new customers and traffic.24 One declares that its network is “available” to all businesses that “pass within 6000 feet”25 and will “provide[] the fiber-optic link from its access network directly into the building.”26 Another emphasizes its willingness to “work together with a customer to construct a spur to that customer from an existing fiber ring.”27 Another will “bring our fiber right up to our customers’ floors in their buildings and provide them with wall-to-wall seamless connectivity.”28 Another will “provide its customers with fiber optic connectivity to virtually any location in its service territory” using a process that is “quick and efficient.”29 Another will connect to “the main Class-A buildings in a downtown business district.”30 CLECs also may extend their fiber networks through fixed wireless connections,31 which can be deployed much more quickly and

2. CLECs Are Making Little Use of Unbundled High-Capacity Loops.

Although ILECs have made unbundled high-capacity loops available nationwide, CLECs are purchasing very few such loops. This is a further, strong indication that CLECs are able to serve the vast majority of their high-capacity customers with their own high-capacity facilities.

As shown in Table 2, CLECs have purchased only 72,000 high-capacity loops in the four Bell companies’ regions combined. By comparison, CLECs have purchased approximately three million POTS loops in the BOC regions. See Figure 2. Virtually all of the high-capacity loops that CLECs have purchased are DS-1 loops. See Table 2 & Figure 2. CLECs have purchased only 140 DS-3 loops, and not a single loop above the DS-3 level. See Table 2.

Even the use of DS-1 loops is minuscule when viewed in relation to the number of lines that CLECs serve using their own loop facilities. CLECs have obtained approximately 72,000 unbundled DS-1 loops, while they are serving at least 12.5 million lines (and likely closer to 20 million) using their own loops. See Table 3; see also Table 1, supra.

B. POTS Loops.

Technologies that compete directly against traditional POTS loops are rapidly being deployed across the country. Today, ILECs are losing about as many lines to wireless and cable networks as they are to wireline CLECs.33 The number of lines served by ILECs has declined for the last three years running – a trend never witnessed before in a century of telephone service.34 See Figure 3. And the trend is all the more dramatic given the year-over-year growth that ILECs have historically experienced. See Figure 4.

1. Cable Networks as Substitutes for ILEC Loops.

Congress anticipated the emergence of cable/telephone competition in 1996.35 In its 1999 UNE Remand Order, however, the Commission was not yet ready to conclude that cable offered a viable alternative to ILEC loops, because service was still “largely restricted to residential subscribers, and [cable] generally supports only one-way service, not the two-way communications telephony requires.”36 As of year-end 1998, cable operators offered two-way capabilities to only about 20 percent of all homes (i.e., to no more than 20 percent of the homes that cable served).37

In the past three years, cable operators have added two-way capabilities to almost all of their networks, using a hybrid-coax-fiber (HFC) architecture. See Figure 5. Cable operators now offer two-way capabilities to approximately 77 percent of all homes (approximately 82 percent of homes passed by cable).38 Two-way capabilities are expected to reach 85 percent of all homes by 2004.39 Although they depend on many of the same upgrades to the cable network,40 these two-way capabilities have been implemented as two distinct services – (1) cable telephony, and (2) high-speed cable modem service.

As discussed in Section II.A.2, at least five cable operators have actually deployed commercial circuit-switched cable telephony. These cable operators currently offer circuit- switched telephony services to about 10 million U.S. homes – approximately 10 percent of all homes – in 20 states.41 In some states, cable telephony is far more widely available than that.42 For example, Cox offers service to nearly all of the one million homes in Rhode Island, and AT&T offers cable telephony services to a large and increasing share of the nearly three million homes its cable network passes in the Boston Area, the approximately 600,000 homes it passes in the Pittsburgh area, the 3.5 million homes it passes in the Chicago area, and the 2.7 million homes it passes in the Bay Area.43

Nationwide, more than 1.5 million homes currently subscribe to cable telephony,44 and 70,000 new subscribers are being added every month.45 There are currently two major cable operators – AT&T and Cox – that are actively deploying circuit-switched cable telephony throughout their cable systems.46 And as a result of its proposed merger with AT&T, Comcast plans soon to deploy cable telephony to about one million homes.47

With HFC in place,48 cable plant can be adapted to provide bare bones switched phone service for about $800 to $825 per line.49 This is the cost for providing “primary line” telephone

Roberts has announced that the merged company intends to begin to deploy telephone service in the Philadelphia and Detroit markets currently served by Comcast, after closing, bringing facilities-based local telephone choice to about one million additional homes.”). 48 Broadband 2001 at 39 (“In addition to high-speed Internet and other high-bandwidth applications, new HFC networks can support telephony service over the cable plant.”). 49 See, e.g., JP Morgan Cable Industry Report at 51-52 (about $375 per line for the actual equipment, another $125-$150 for the labor, and $300 for customer premises equipment); AT&T Broadband, Investor Presentation at 37 (July 2001) ($825 per line); NCTA Cable Telephony Report at 10 (“Cox, which has installed 11 switches in its largest markets, estimates its switching costs at $105 per customer (assuming a penetration rate of 25 per cent of homes passed and an average take-rate of 1.5 lines per customer). In addition, Cox spends and additional $505 per customer for the Network Interface Unit (NIU), the drop, the tap and the Headend Interface Terminal (HIT). This combined variable cost of $610 per customer for the provision of local telephony is in addition to the $220 per home passed that Cox must invest to upgrade its cable plant to 750 MHz capacity and to introduce two-way interactivity. It also does not include the $100 per customer that Cox is investing to power its cable networks to ensure that telephone service continues in the event of a power failure.”).

service.50 Cable telephony systems use the same, commercial, circuit switches and perform all the same functions as ILEC POTS services.

The imminent deployment of IP cable telephony will further accelerate the availability of cable networks as a competitive substitute for ILEC voice loops. As described in Section II.B, each of the major cable operators is now conducting trials of IP cable telephony, or has indicated plans to do so. Commercial deployment of the service as a secondary-line service is expected to begin within the next year or so;51 there are expected to be between five and seven million cable IP telephony subscribers by 2006.52 Cable operators are expected to deploy primary-line IP cable telephony service shortly thereafter.53

Cable operators also provides high-speed Internet access services, which compete directly with ILEC loops that have been used mainly for connecting to the Internet. In the past, many customers bought second phone lines for their computers, to support dial-up Internet connection. Second-line usage peaked in 1999, when approximately 27.5 percent of all households were buying second lines,54 which they used mainly as dedicated data lines.55

Many of those same households are now buying broadband connections instead, and about two out of three of those connections are over cable.56 As of year-end 1998, cable modem service was available to approximately 20 million homes, or roughly 20 percent of the U.S. mass market,57 and there were approximately 500,000 cable modem subscribers.58 Today, the service

is available to between two-thirds and three-quarters of all U.S. homes,59 and approximately 7.5 million homes subscribe.60 One respected analyst now predicts that cable “will capture around 65% of the secondary line market by 2006.”61

2. Mobile Wireless as Substitute for POTS Loops.

At the time of the UNE Remand Order, the Commission concluded that wireless phones did not yet offer a sufficiently robust competitive alternative to ILEC loops to justify any cut back on availability of the loop UNE.62 Wireless service areas were less ubiquitous; they did not offer the same functionality; their data capabilities were “generally inferior;” and their sound quality was not always as good.63 Wireless links offered “promising” but “not yet viable alternatives” to wireline loops.64

As discussed in more detail in Section II.C, conditions have changed significantly since that time. Independent experts now almost uniformly conclude that wireless is a significant competitive substitute for second-line service today.65 For example, IDC found that, as of year- end 2001, “10 million wireline access lines will have been displaced by wireless, primarily by consumers choosing wireless service over installing an additional access line at home.”66 IDC estimates that, by 2005, wireless phones will replace 30 to 35 percent of second and additional wireline access lines.67 Many other independent analysts have reached similar conclusions.68

59See Morgan Stanley Cable Modem/xDSL Report at Exh. 3 (estimating 75 million homes passed by cable modem service as of year-end 2001); JP Morgan Telecom Services 2001 Report at Table 15 (estimating 106.4 million US households as of year-end 2001) (74.92/106.4 = 70.4 percent of US homes passed by cable modem service); see also NCTA Industry Statistics (70 million homes passed by cable modem service as of November 2001); Yankee Group Consumer Broadband Report at 4 (“At year-end 2001, approximately 66% of the households in the United States will have cable modem service available to them.”); Broadband 2001 at Table 6. 60 See Morgan Stanley Cable Modem/xDSL Report at Exh. 3. 61 JP Morgan Cable Industry Report at 53. 62 UNE Remand Order ¶ 188. 63 Id. 64 Id. 65 Wireless service also clearly competes directly, today, against wireline payphone service and other wireline services used outside the home and regular office – hotel phones, for example. See, e.g., Sixth CMRS Report at 32 & n.211; Michael Powell, Chairman, FCC, Question and Answer with Chairman Powell, remarks before the Forrester Research Telecom Forum (May 21, 2001) (“I haven’t picked up the phone in a hotel in five years, because I use my wireless phone.”). 66 IDC Wireless Displacement Report at 1; see also Zacks All-Star Analyst Issues Recommendations for 5 Stocks, PR Newswire (Nov. 15, 2001) (Drake Johnstone, Davenport & Co.: “[C]onsumers are using their wireless phone line as a second phone line.”); T. Fowler, The Low Cost of Going Wireless; More Callers Cut Cords As Cell Phone Rates Fall, Houston Chronicle (Aug. 8, 2001) (“Many [people] are using [wireless phones] as replacements for second lines in their homes.”). 67 See IDC Wireless Displacement Report at Figure 15. 68 See, e.g., Forrester Sizing US Consumer Telecom Report at 9 (“Over the next five years, the mobile business will take a cut at fixed-line revenues. Wireless operators will ravage the fixed-line business as 5.5 million customers give up secondary lines.”); JP Morgan Telecom Services 2001 Report at Table 26 (By 2006, over 2.8 million IV-12

Wireless is now becoming increasingly competitive with primary line wireline services as well. A Yankee Group survey in early 2001 found that about 3 percent of wireless subscribers had now abandoned wireline in favor of wireless entirely.69 A wireless industry association has estimated that the number as of that date “could be as high as 5 percent.”70 A recent USA Today/CNN/Gallup poll found that 18 percent of cell phone users “use cell phones as their primary phones.”71

Many wireless carriers are now marketing their services as direct substitutes for wireline service. The Commission’s Sixth CMRS Report, for example, describes the Cricket service offered by Leap Wireless – a service offered “at a flat rate, paid in advance each month,” in order to be “competitive with traditional landline service.”72 As noted by one industry publication, the Cricket business model “has been successful enough that several regional carriers have started offering their subscribers ‘Leap-alike’ plans,” including ALLTEL’s “Boomerang,” US Unwired’s “Freedom Plan,” and Dobson Cellular’s Cellular One “Breeze” service.73 VoiceStream’s advertisements exhort customers to abandon their wireline phones,74 and the company’s CEO states that they “view wireless as a replacement for wireline.”75

So far as service quality is concerned, wireless is now fully competitive with wireline – and better than competitive in one key respect. In almost all major markets, wireless carriers now offer digital calls with connection quality comparable to the quality of wireline service,76 people will have substituted a wireless phone for a secondary line.); Gartner U.S. Residential Wireline Report at 11 (“Of all households reporting a residence access line replacement over the past six months, 2.3 million or 33 percent of lines were replaced with a cellular/PCS phone.”). 69 Sixth CMRS Report at 32 (citing Yankee Group survey cited in J.

Nearly 80 percent of wireless customers now subscribe to high-quality digital service;77 dial-up wireline service, by contrast, remains overwhelmingly analog.78 The rate of busy circuits and dropped calls on wireless networks is improving rapidly.79 Wireless E911 location capability is now virtually the same as wireline capability, and it is being rapidly deployed.80 And wireless service is unambiguously superior to wireline in that the wireless phone is mobile. Mobility is, self evidently, a very valuable feature, and one that has historically commanded a high price premium in the market.

Wireless is now price competitive with wireline services, particularly when the comparison is made between equivalent bundles of service. The typical wireline customer purchases not only basic local service, but also long-distance service and some number of value- added features like call waiting, voice mail, or caller ID.81 Wireless carriers typically provide all of these add-on services, and often for no extra charge.82 Taking into account the whole package of service most typically sold, a November 2001 Gartner Dataquest study accordingly concludes that wireless calling prices are already “competitive with, and in some case better than, wireline calling rates.”83 And wireless prices continue to decline rapidly – by as much as 10 to 20 percent a year in recent years.84

77 See, e.g., Dr. Robert F. Roche, CTIA, Measuring Wireless Today, http://wireless.fcc.gov/services/cmrs/ presentations/Bob_Roche_Feb_28_FCC_presentation.pdf (showing approximately 25 million analog subscribers as of June 2001, compared to about 100 million digital subscribers); see also Sixth CMRS Report at 6 (“[A]t the end of 2000, digital customers made up 62 percent of the industry total, up from 51 percent at the end of 1999 and 30 percent two years ago.”). 78 See FCC Statistics of Common Carriers, 2000/2001 ed. at Table 2.3 (162 million analog switched access lines compared to 10 million digital lines). 79 See, e.g., Gartner U.S. Residential Wireline Report at 11 (“It is only over the last year that there has been a measurable shift by consumers to replace their wireline access lines with the cellular/PCS alternative – clearly an indication that cellular/PCS has overcome the quality and reliability weakness in the mind of the consumer.”); AARP, Understanding Consumer Use of Wireless Telephone Service, http://research.aarp.org/consume/ d17328_wireless_1.html. (“Wireless telephones are becoming more popular in the United States as the cost has become more affordable and the quality of wireless service has improved.”). 80 See, e.g., Thomas J. Sugrue, Prepared Testimony before the Subcommittee on Communications, Committee on Commerce, Science, and Transportation, United States Senate, at 6 (Oct. 16, 2001) (“Wireless location technology is available, is being deployed in networks and handsets, and is capable of accurately locating 911 callers.” By October 2002, “the location of 911 calls will be reported in most instances with an accuracy of 100 meters or less. Network equipment and handsets with location capability are now being manufactured and sold to meet and exceed this benchmark.”). 81 See, e.g., JP Morgan Cable Industry Report at 50 (the average voice customer generates approximately $58 in monthly revenues, only $18 of which is for basic local service; the average revenue generated for vertical features is nearly $5, and the average revenue generated in access charges is about $5.50). 82 See, e.g., Sprint PCS, Sprint PCS Wireless Service Plans, http://www1.sprintpcs.com/explore/servicePlans OptionsV2/PlansOptions.jsp (All Sprint PCS service plans include voicemail, call waiting, caller ID, numeric paging, and three way calling.); VoiceStream, Products and Services, Rate Plans, http://www.voicestream.com/products/ services/rateplans/dc_balt.asp (all VoiceStream plans include voicemail, call waiting, caller ID, built-in paging, and conference calling). 83 Gartner U.S. Consumer Telecommunications and Online Market Report at 33. 84 See, e.g., Sixth CMRS Report at 6.

3. Direct Competitive Overbuild of ILEC Loops.

A number of CLECs are now building their own all-new loop facilities to serve residential customers. The business plans of these CLECs typically involve the provision of service to one small geographic area at a time – anywhere from a single apartment building to a small cluster of homes. They also often involve the deployment of facilities that enable the provision of more than just basic voice service, but video and broadband Internet services as well.

A number of smaller incumbent local exchange carriers have established CLEC affiliates in order to “target RBOC markers that are geographically proximate to their existing ILEC holdings.”85 See Table 4. This geographic “edge-out” strategy enables the CLEC “to take advantage of the synergy of its ILEC and CLEC operations while entering typically underserved non-urban markets.”86 The CLEC may, for example, “leverage the excess capacity on [its] existing plant to reduce startup and entry costs.”87 In many cases, such CLECs will “begin marketing mobile wireless service in new markets before their entry into the competitive market,” so that when they “enter the new wireline markets, customers are already familiar with their reputation and quality of service, providing the [CLEC] with significant competitive advantage.”88

Another overbuild strategy involves the deployment of a broadband pipe (generally either hybrid fiber coax or pure fiber) to provision high-speed bundled service offerings to individual neighborhoods or the approximately 30-35 percent of the population that live in multi-dwelling units. See Table 5.89 Several CLEC affiliates of incumbent LECs – including PennTel and Hickory Tech – have taken this approach.90 This also has been the strategy of RCN, which has been “constructing advanced networks in select markets with high levels of population density and favorable demographics along the West and East Coasts, along with Chicago.” 91 In the fourth quarter of 2001 alone, RCN added nearly 47,000 new subscriber connections (including

about 16,000 voice connections) to its network.92 In the approximately four years since it began the process, RCN has built out is network to pass more than 1.5 million homes.93

In addition to overbuilding ILEC networks, some CLECs are pursuing a “greenfield” strategy, which involves deploying facilities in brand-new developments where there is no incumbent provider. For example, in its “Greenfield markets” in Charlotte and Raleigh, CTC deploys “our own remote switching equipment, as well as build a distribution system to in effect, become the local telephone company for each new development.”94 CTC is “working with developers and builders to become the ‘official telecommunications provider’ for their developments.”95 The company states that, “[b]y clustering our projects, we are able to gain capital and service efficiencies.”96 As of September 2001, CTC was “adding about 1,000 CLEC lines a month.”97 Another CLEC – BTI – is targeting new “residential developments,” and was awarded a major contract for a large development in Chapel Hill that includes “three schools, a 500-acre commercial tract and 4,000 homes.”98

C. Broadband Loops.

Broadband services are provided over the telephone network using (DSL) technology, which relies on the same local loop plant used to provide narrowband voice service.

DSL over ILEC loops is only one of four main last-mile technologies that is currently used to provide broadband services to mass-market consumers. The other three are cable modem, satellite, and fixed terrestrial wireless. Both consumers and providers view all four of these various broadband services as interchangeable. Two or more of the main broadband technologies are frequently available in the same geographic areas.

Cable is the clear leader in the broadband market today, by a wide and growing margin. Cable modem service is currently available to between two-thirds and three-quarters of U.S. households,99 whereas DSL service is available to only about 45-50 percent.100 See Table 6. As of the year-end 2001, there were approximately 7.5 million cable modem subscribers in the U.S., compared to 3.3 million residential DSL subscribers.101 See Figure 6. According to analysts,

99 See Yankee Group Critical Mass Report at Exh. 4; Broadband 2001 at Table 6. See also NCTA Industry Statistics (as of November 2001, 70 million households were passed by cable modem service). The cable industry association estimates that, by year-end 2002, approximately 95 million U.S. homes (or nearly 90 percent of homes passed by cable) will have access to cable modem service. See NCTA, Cable & Telecommunications Industry Overview 2001 at Chart 2 (2001) (citing Morgan Stanley, Dean Witter, Broadband Cable Second-Quarter Review at 9 (Aug. 29, 2001)). 100 See, e.g., Yankee Group Critical Mass Report at Exh. 4 (estimating that DSL will be available to 45 percent of all households by year-end 2001); JP Morgan Cable Industry Report at Figures 12 & 36 (DSL available to 43 percent of U.S. homes as of 1Q2001); P. Roche, DSL Will Win Where It Matters, McKinsey Quarterly 2001, No. 1 (2001) (“40 percent of all phone lines are ready for DSL”). 101 See Morgan Stanley Cable Modem/xDSL Report at Exh. 3 (cable modem); TeleChoice DSL Deployment Summary (residential DSL).

approximately one-third of all U.S. households currently have access to both cable modem and DSL service,102 and approximately three-quarters of all homes with access to DSL also have access to cable modem service.103

Cable is adding new subscribers at a faster rate than competing high-speed technologies. See Figure 7. And most analysts expect cable to maintain a considerable lead over DSL and other broadband technologies for the foreseeable future.104 The principal reason is simply that

102 See, e.g., JP Morgan Cable Industry Report at Figures 12 & 36; Broadband 2001 at Chart 25. 103 See, e.g., JP Morgan Cable Industry Report at Figures 12 & 36 (JP Morgan estimates that as of 1Q 2001, 10 percent of households had access to DSL only, and 33 percent had a choice of DSL or cable; therefore, approximately one-quarter of households with access to DSL did not have access to cable (10/43=23.3)). 104 See, e.g., Broadband 2001 at Table 9 (estimating that by 2005, cable will have 51 percent of broadband subscribers, while DSL will have 37 percent.); Yankee Group Consumer Broadband Report at Chart 1 (predicting that by 2005, cable will have 48.5 percent of high-speed users, while DSL will have 33.8 percent); Salomon Smith Barney Battle for High-Speed Data Report at 1 (cable will account for 59 percent of subscribers and DSL will account for 34 percent in 2005); M.

cable modem service is more widely available than DSL.105 While analysts expect the gap between cable and DSL to narrow somewhat, it is expected that by 2005, cable will still reach 12 to 15 percent more homes than DSL will reach by that time. See Table 6.106

Cable’s advantage is that all cable plant is upgradeable; a significant fraction of the existing telephone plant is not. DSL is provided over the existing local telephone network by connecting digital modems over copper loops to the central office, and then ensuring that those loops are free from various electronics (e.g., load coils) that are needed for voice service but that inhibit the provision of data services.107 DSL service can be provided at high speeds only on loops that are 18,000 feet or shorter,108 which means that “only about two-thirds of U.S. homes are easily addressable for xDSL.”109 And even with respect to the homes that can be upgraded,

which finds that, in 2005, 45 percent of high speed subscribers will go with cable and 40 percent will go with DSL.); TeleChoice Sees Slower But Still Substantial Growth in DSL, xDSL.com (Aug. 13, 2001), http://www.xdsl.com/ content/tcarticles/wp081101.asp. 105 See, e.g., JP Morgan Cable Industry Report at 36 (“Assuming that each platform takes 50% share in markets where both services are available, cable enjoys a more than 2:1 advantage in what each platform’s “natural” market share would be, holding all other variables – price, performance, bundling benefits – constant.”). 106 See, e.g., Yankee Group Critical Mass Report at Exh. 4 (cable modem service is expected to be available to 83 percent of households by 2005, while DSL service is expected to be available to 74 percent of households.); Broadband 2001 at Chart 32 (projecting that about 70 percent of households will have both cable modem and DSL service available by 2005). 107 There are two main variations of DSL: asymmetric (ADSL), which has a higher downstream than upstream transmission rate; and symmetric (SDSL), which offers an equal downstream and upstream rate. ADSL is the most common form of DSL, and is used most often with residential customers, whereas SDSL is used primarily for business customers. See Second Advanced Services Report ¶¶ 36-37. 108 See, e.g., A. Gilroy & L. Kruger, Broadband Internet Access: Background and Issues, Congressional Research Service – Policy Papers (May 18, 2001); D. Sweeney, Ultra Long-Reach DSL : A Whole New Crop of Companies Aims To Boost DSL Performance, America’s Network (Sept. 15, 2001). 109 Broadband 2001 at 40.

cable has lower upgrade costs than DSL.110 This means “that relative to its telco competitors, [cable] has the retail pricing power to under-price competitors while preserving an attractive return.”111

The two wireless broadband services widely deployed today are broadband provisioned via satellite and terrestrial fixed wireless broadband (MMDS). Broadband satellite services are provided using the same constellation of Direct Broadcast Satellites (DBS) that currently provide video services to more than 17 million subscribers.112 DBS companies have, in the last year, deployed a two-way high-speed Internet service capable of competing on equal footing with cable modems and digital subscriber lines.113 The main fixed wireless services provided to residential customers use Multichannel Multipoint Distribution System (MMDS), which uses spectrum in the 2 GHz band.114 WorldCom and Sprint “own most MMDS spectrum in the United States,” and “have commercially deployed MMDS in a handful of markets.”115 WorldCom has recently stepped up efforts to deploy MMDS service, and has begun offering service in four new markets since the beginning of 2002.116

Subscribership numbers for broadband satellite remain low: there are an estimated 200,000 subscribers to two-way satellite and fixed wireless broadband services as of year-end 2001.117 But analysts project that these totals will soon begin to rise rapidly.118 Whereas

110 See, e.g., Broadband 2001 at 69 (“xDSL starts life at a much higher cost point (close to $800) than cable modem (about $470) primarily because cable makes use of shared head-end terminating equipment, whereas DSL requires dedicated line cards for each subscriber.”). 111 Bear Stearns Byte Fight! Report at 82. 112 See Eighth Video Competition Report, App. C at Table C-1; SkyReport, National DTH Counts: November 2000 – November 2001, http://www.skyreport.com/dth_us.htm. 113 Broadband 2001 at 45 (a “true advantage” satellite data services have over wireline alternatives is “instant near-ubiquity”). 114 See Broadband 2001 at 131. 115 Broadband 2001 at 47. In October 2001, Sprint announced the end of customer acquisition for MMDS services, and a freeze on the number of MMDS markets served “until substantial progress is made on second- generation MMDS technology. The current MMDS customer base will be maintained, as will all video services offered through the fixed wireless spectrum.” Sprint Press Release, Sprint to Terminate ION Efforts (Oct. 17, 2001). 116 See WorldCom Press Release, WorldCom Launches New High-Speed, Fixed-Wireless Service in Lafayette (Feb. 21, 2002); WorldCom Press Release, WorldCom Launches New High-Speed, Fixed-Wireless Service in Pensacola (Feb. 20, 2002); WorldCom Press Release, WorldCom Launches New High-Speed, Fixed-Wireless Service in Springfield (Jan. 9, 2002); WorldCom Press Release, WorldCom Launches New High-Speed, Fixed-Wireless Service in Hartford (Jan. 8, 2002). 117 See Yankee Group Fiber and Fixed Wireless Report; Echostar Hopes New Plan Will Boost Deal’s Chances, Communications Daily at 3 (Feb. 27, 2002). 118 See, e.g., Yankee Group Consumer Broadband Report at 4 & Exh. 1 (“[S]atellite broadband will reach 300,000 households in the United States by the end of this year and grow to 4.5 million households by the end of 2005 . . . this will translate into a market share jump from 2.81% at the end of 2001, to 14.48% at the end of 2005.”); Broadband 2001 at Table 9 (estimates show satellite market share expanding from 1 percent in 2000 to 10 percent in 2005); Business Communications Company, Inc. Press Release, Market for Broadband Internet Access Continue to Soar (Nov. 1, 2001) (“Two-way satellite broadband Internet access will be the fastest growing single-access technology, with expenditures growing at an AAGR of 36.6% from $ 1.14 billion (or 12.8% of all broadband related expenditures) to $ 5.42 billion, or 20.5% of expenditures.”).

IV-21

wireline services generally get rolled out incrementally, wireless services tend to get “turned on” for an entire geographic area in a single step. Wireless, by its nature, generally provides complete geographic coverage in a region – or, in the case of satellite service – the entire country. That wireless providers currently lag behind wireline providers in serving broadband customers reflects the none-to-all dynamic of wireless roll out, more than anything else.

Several companies also plan to offer residential broadband services using unlicensed spectrum bands, including the 2.45 GHz Industrial-Scientific-Medical (ISM) band and the 5.8 GHz Unlicensed National Information Infrastructure (UNII) band.119 As noted above, WorldCom has recently accelerated its efforts to deploy MMDS service. Customers within “35 miles of a centrally located transmittal tower” can obtain “high-speed broadband Internet access in as little as five to ten days.”120 The Commission’s staff found that the “MDS industry has invested several billion dollars to develop the band for fixed wireless data systems,” and that “these systems will provide a significant opportunity for further competition with cable and digital subscriber line (DSL) services.”121

Competitors are supplying last-mile broadband connections to small business customers, as well as residential customers. Cable operators are beginning to extend their cable networks to provide high-capacity loops to serve small and medium-sized business customers. This push is being driven by the advent of next-generation Voice-over-Internet-protocol technology, which has “solved” “previous difficulties such as [Quality of Service] problems, incompatible and incomplete standards, and lack of equipment.”122 Today, “[b]usiness trials of [Fiber to the Business] are underway . . . with deployment expected this spring.”123 Numerous cable operators already have realized that there are many businesses that lie in close proximity to their networks, and that it makes sense to build out their networks incrementally to serve them.124

119 See Broadband 2001 at 49 (“A host of small start-ups are deploying some limited services over unlicensed bands, and some larger providers are running unlicensed spectrum trials.”); S. Buckley, MMDS Hits the Airwaves, Telecommunications Magazine (Feb. 2001) (“IGI Consulting predicts that by 2005, there will be at least 1000 unlicensed wireless ISPs in operation and 1.3 million subscribers. . . . Unlike licensed MMDS holders that are restricted by the FCC’s stringent rules, unlicensed carriers such as Clearwire, Fuzion Wireless and PSInet can set up shop immediately.”). 120 WorldCom Press Release, WorldCom Launches New High-Speed, Fixed Wireless Internet Service in Springfield (Jan. 9, 2002). 121 Carroll McHenry, Chairman and CEO, Nucentrix Broadband Networks, Third Generation Wireless, remarks before the Senate Subcommittee on Communications, Committee on Commerce, Science and Transportation, Washington, D.C.

Satellite providers have designed service offerings specifically targeted at small business customers. For example, Hughes offers DirecWay service, which is a “business edition Internet access” service that gives “small business[es] access to the same advanced technology that powers global enterprises.”125 The DirecWay service gives business customers the option of much higher throughput and downstream bandwidth than is available with Hughes’s basic consumer offering.126 WorldCom has announced that it would be reselling Hughes’s DirecWay Service to small- and medium-sized business customers beginning in January 2002, and rebranding that service with WorldCom’s name.127

While the provision of broadband services is undeniably competitive today, the most important competitive opportunity over the longer term centers on the chase for far more bandwidth than existing “broadband” networks currently offer. The upgrading of cable, telephone, and wireless networks will not end in the foreseeable future; appetites for bandwidth continue to grow faster than infrastructure can be built. Cable and telephone companies alike will push fiber deeper and deeper into the local exchange, until it finally reaches the home. Wireless providers will multiply and shrink cells, and boost capacities, to keep pace. Much of this new infrastructure will have little relation to the old. ILECs will accordingly enjoy no particular advantages over competing carriers in deploying this new infrastructure.

V. FACILITIES-BASED COMPETITION VERSUS RESALE

The Commission has affirmed that, “in the long term, the most substantial benefits to consumers will be achieved through facilities-based competition.”1 “Facilities-based competition is the ultimate objective” of the Commission’s competition policy.”2 At the same time, however, the Commission has attempted to craft its unbundling regulations to promote the “rapid introduction of competition in all markets.”3 The Commission’s other stated objective has been to encourage CLECs “to serve the greatest number of consumers as rapidly as possible.”4

Experience since the 1996 Act establishes that facilities-based competition has evolved largely apart from UNE-based forms of competitive entry – and that regulatory policies focused on promoting the indiscriminate use of UNEs advances the short-term appearance of competition over the long-term substance.

The enormous increase in facilities-based competition over the past six years has had very little to do with the availability or use of UNEs. Competitors have instead relied on facilities-based strategies from the outset. They have grown incrementally, establishing a foothold and then expanding core network facilities step by step into new geographic and product markets. Over time, this strategy has delivered robust competition to very significant numbers of both business and mass-market customers.

Overall, however, the current regulatory structure has favored the rapid proliferation of small, under-funded, technically unsophisticated competitors, over the more measured evolution of robust and durable ones. All too often, it has been easier and cheaper for a CLEC to piggy- back on the incumbent’s network permanently rather than build out a network of its own. Such CLECs have attempted to enter local markets very rapidly, on a very large scale, by relying predominantly – and all too often exclusively – on UNEs. The Commission expected these competitors to rely on UNEs only until it “was practical and economically feasible to construct their own networks.”5 But many CLECs have adopted business strategies that center on long- term reliance on UNEs, with no expectation at all of ever building facilities to replace them. A significant number rely on ILEC networks from end-to-end, which they do primarily through the

effective “resale” of ILEC service that is made possible by the unrestricted availability of the UNE Platform.

Many of the CLECs pursuing UNE-centric strategies have failed. Investors have recognized that these CLECs are engaged in highly speculative ventures of regulatory arbitrage, and offer no true value of their own. The UNE-centric CLECs have harmed their facilities-based counterparts, too. Facilities-based CLECs recognize that the unrestricted availability of UNEs priced at a regulator’s estimation of long-term incremental cost can ruin a business making steep capital investments at here-and-now, real-world prices. These facilities-based CLECs view the availability of the full UNE Platform as particularly harmful to facilities based competition. See Table 1.

Table 1. CLECs Opposing the Availability of UNE Platforms Allegiance Telecom, Cablevision Lightpath, Cbeyond Communications, Time Warner Telecom, XO: “[T]he evidence submitted in this proceeding since the UNE Remand Order was released confirms that competition is thriving in markets where the requirement to provide unbundled switching has been removed.” Allegiance Telecom: Expanding “the availability of the UNE-P” “threatens to harm those CLECs that have built their own facilities and do not need to rely on the UNE-P to serve customers.” UNE-P pricing levels “could well be too low,” which “mak[es] it more difficult for efficient, facilities-based [competitive local exchange carriers] to compete.” “[O]nly carriers that make investments in networks and equipment are able to deliver the product, technology and service innovations that provide competitive alternatives to the ILEC.” Choice One: “Choice One’s business experience demonstrates that new entrants can provide service to small business customers . . . without the need to rely on unbundled local switching purchased from an incumbent LEC. . . . We are unaware of any reason why another carrier could not replicate it using unbundled loops and self- deployed switches, even in second and third tier urban markets. The Commission’s rules governing unbundled local switching should reflect this fundamental fact.” TCG (pre AT&T merger): The FCC should “ensure that wholesale competition does not drive out or diminish the development of strong, facilities-based competition.” Sources: See Appendix M.

Based on the first comprehensive study of its kind, one of the Commission’s own economists recently found that “states with lower UNE prices have less facilities-based entry.”6 Other noted economists, scholars, and jurists have reached the same conclusion: unbundling ultimately undermines facilities-based investment.7 If an incumbent carrier aggressively sold its

own services below cost on its own initiative, or even just pared prices down to zero-margin “imaginary network” levels, it would be accused of “predatory pricing” – of attempting to discourage or ruin real competitors that were building competing networks alongside.

The unrestricted availability of UNEs discourages new ILEC investment, too. There is no incentive to invest in risky new infrastructure when the threat of future unbundling mandates directed at those facilities eviscerates the business case for deploying them. As AT&T’s chairman has put it, “[n]o company will invest billions of dollars to become a facilities-based broadband services provider if competitors who have not invested a penny of capital nor taken an ounce of risk can come along and get a free ride on the investments and risks of others.”8

But facilities-based investment is precisely what is needed. As the Commission has recognized, “the widespread deployment of broadband infrastructure has become the central communications policy of the day.”9 This will require “the complete or near-complete replacement of copper lines with end-to-end fiber optic transmission facilities.”10 The existing UNE regime significantly discourages investment in this new infrastructure, by both the facilities-based CLECs, and by the ILECs themselves.

A. Efficient Facilities-Based Entry.

The robust levels of competition now offered by numerous CLECs establish that facilities-based competition is possible. The business strategy that works is to enter by way of high-margin markets and value-added markets: the urban carrier and business markets first targeted by local fiber companies, and the wireless and broadband markets targeted by wireless, cable, and other facilities-based providers of switches and alternative forms of transport. These have been the successful entry points; facilities-based competition for the rest of the market has spread out rapidly from there.

1. Incremental Development of Facilities-Based Competition.

As demonstrated in Section I, the CLEC industry as a whole remains healthy. The most successful individual CLECs are those that have pursued a strategy of facilities-based entry. Their common business strategy has been to deploy facilities to serve high-margin markets first, then build out from there, to extend their competitive reach incrementally, into new service sectors and new geographic markets.

None of the successful competitors has emphasized factors that the Commission has at times deemed important – factors such as “ubiquity,” or “rapid[]” entry to serve “the greatest number of customers.”11 None of the successful competitors has viewed ubiquitous service or instant roll-out as competitively necessary. None has proceeded on the assumption that the evolution of its business required the very rapid development of a very large footprint. To the contrary, they have prospered by emphasizing just the opposite, at the outset: smaller operations, carefully targeted at the most profitable geographic and service sectors.12 Much broader competition has then evolved relentlessly from these facilities-based beachheads. And it has now reached the point where it is developing very rapidly indeed.

Switching. As discussed in Section II, competitive switches were first deployed by large business customers and then by competitive-access providers. This base of competitive switching capacity has since evolved, market by market, to serve smaller business customers and, most recently, residential subscribers. Adding customers and traffic at the margin has grown progressively cheaper. A switch deployed initially to serve the single large customer at a single point then serves a number of smaller customers, and then becomes part of larger network, serving additional, smaller, more widely dispersed sources of traffic.

Packet switching services have evolved in similar fashion. High-speed ATM and frame relay switches are deployed first to provide high-margin broadband data services. E-mail and messaging then begin to substitute, at the margin, for voice calls. Then two-way voice traffic migrates on to these packet switches.

As discussed in Section II, this evolutionary process is now robustly established, and the business model is well understood and mature. There are large numbers of competitive circuit switches in actual service. They can and do serve both large business and mass-market customers. Their geographic reach can be extended with trunks to remotes, and frequently is. Packet switches are multiplying even faster, and packet-switched traffic is now making very substantial in-roads into service areas traditionally served by circuit switches.

Fiber, Transport, and High-Capacity Loops. Competition has evolved in a similar fashion in the markets for transport and high-capacity loops. The interoffice transport and local

11 UNE Remand Order ¶ 107. 12 See, e.g., Time Warner Telecom, Company Growth, http://www.twtelecom.com/cgrowth.html (“growth plans focus on geographic expansion, extension into new market segments and development of new data and Internet- based products and services.”); V. Bajaj, Allegiance Will Borrow $ 350 Million to Invest, Dallas Morning News (Sept. 19, 2001) (Allegiance has “pursued a more deliberate and slower national expansion than most of its competitors.”); Royce Holland, The Top Enterpreneurs, Bus. Week (Jan. 14, 2002) (While its “rivals took on mountains of debt, the chief executive of Allegiance Telecom played it safe, borrowing little and expanding slowly.”).

loop UNEs are both wireline facilities that transmit information between two fixed points. Here again, the early competitors first targeted a small number of high-margin opportunities, then built out from there. In the mid-1980s, “competitive access providers” ran their networks to the very largest customers in the largest geographic markets – long-distance carriers in the densest urban areas. Then, year by year, the CAPs extended both their networks and their businesses, to serve business customers, and less densely populated areas. Again, this process has matured; there are now extensive networks in place in all major urban markets.

Once a fiber network is deployed and the investment sunk, the facilities can be used to serve other on-net customers, including many whose traffic volumes would never have justified the original deployment of the network. Similarly, networks can be economically extended block by block, to points that would never have been economical to reach mile by mile. When they deploy fiber, carriers invariably deploy far more capacity than they can use immediately, to facilitate precisely this process of incremental future development.

This process of competitive evolution is now accelerating rapidly, for two reasons. Extensive competitive networks are already in place; the marginal cost of extending them to pick up new customers is far lower, now, than it was at the outset. And surging volumes of data traffic make the deployment of competitive fiber increasingly economical, for an ever-expanding base of potential customers. CLECs now routinely offer service to many business customers that are not already served by their fiber networks; the CLEC will extend its network one spur or branch at a time, to pick up the new traffic.

Narrowband Loops. Wireless has emerged as a serious competitor to the narrowband ILEC loop through a similar, at-the-margin process of upgrading the network and capturing economies of scope and scale. Wireless began as a high-priced service for the handful of high- end customers willing to pay a high premium for a mobile loop. Over time, wireless operators were able to begin competing for a greater segment of customers willing to pay for mobility. As they have built out their networks, wireless carriers have begun to compete directly for virtually all second-line loops, and for an increasing share of primary-line loops as well.

Cable, which offers not one but two important alternatives to the ILEC loop, has evolved as competitive alternative in a similar way. Coaxial cable networks were originally deployed to offer video. With these networks in place, a number of cable operators found it economical to add circuit-switched voice telephony and high-speed data capabilities. Cable now competes directly against ILEC loop for the last-mile transport of packet-switched data traffic, which now accounts for substantially more than half of all telecom traffic. And in many areas, cable competes directly with ILECs for primary line voice service as well.

Broadband. A broadband link to the packet-switched network provides a connection to all other Internet users, whether linked through telephone lines, cable modems, land-based wireless connections, or satellite connections. In the past three years, cable operators have completed outfitting the vast majority of their networks with two-way capabilities. Almost all cable operators are now rapidly deploying high-speed data capabilities. The costs of upgrading cable plant have been falling steadily, and cable operators have captured very significant economies of scope in deploying digital platforms that can be used for digital television and high-speed data, as well as packet-switched voice.

V-5

Much of the new broadband infrastructure has had little relation to the old. Fiber has replaced copper in the loop; packet switches have replaced circuit switches in the central office; and the transport between these packet switches has used very different routes than the rigid point-to-point connections between central offices. In deploying this new infrastructure, ILECs have thus enjoyed no particular advantages over competing carriers.

2. Economies of Scope and Scale.

In the UNE Remand Order, the Commission found that, “[b]ecause competitors do not yet enjoy the same economies of scale, scope and ubiquity as the incumbent, they may be impaired if they do not have access, at least initially, to certain network elements supplied by the incumbent LEC.”13 As discussed above, however, the assumption that immediate scale and scope economies are essential to competitive success is not borne out by actual experience in the marketplace. The successful competitors have started out with high-margin business strategies, not high-volume strategies, and expanded incrementally from there. The economies of scope and scale have followed, not led, the competitive process.

With that said, incremental growth has now culminated in a significant number of CLECs that enjoy very significant economies of scale. As Table 2 indicates, the twenty largest CLECs today have 100 percent more switches, 190 percent more fiber-route miles, and earn 150 percent more in total revenues than the twenty largest CLECs at the time of the UNE Remand Order. See Table 2.

Switches. At the time of the UNE Remand Order, only 15 CLECs had deployed 10 or more circuit switches, and only 6 had deployed 20 or more. See Figure 1. Today, at least 27 CLECs have deployed 10 or more circuit switches, and at least 16 have deployed 20 or more. See id. The increase in the size of CLEC data networks has been equally dramatic. At the time of the UNE Remand Order, only 20 CLECs had deployed 10 or more packet switches, and only 11 CLECs had deployed 20 or more. Today, at least 27 CLECs have deployed 10 or more packet switches, and at least 23 CLECs have deployed 20 or more. See Figure 2.

Wireless Alternatives to the Narrowband Loop. At the time of the last UNE review, there were only three “nationwide” mobile telephony operators, as the FCC defines that term.14 Today, there are six nationwide operators.15 At the time of the last UNE review, the ten largest mobile wireless operators had an average of 5.1 million subscribers each. Today, the ten largest mobile operators have an average of 9.4 million subscribers each.16

Broadband Alternatives to the High-Frequency Loop. At the time of the last UNE review, deployment of broadband was still “in the early stages of development.”17 At that time, cable operators had only about 300,000 broadband customers.18 Today, by contrast, cable operators have approximately 7.5 million broadband customers.19

3. Emergence of Competitive Resale Markets.

Across the board, competition has now advanced to the point that competitive wholesale markets are now emerging. The players in these markets are the markets’ own answer to the Commission’s UNE regime – they offer reasonably close analogies to unbundled network elements, at wholesale prices.

As discussed in Section III.C, there has been a dramatic increase in fiber supplied by alternative wholesale suppliers. These players typically sell or lease dark fiber to other carriers, but do not themselves engage in the provision of telecommunications services. They have raised about $2 billion in capital since the third quarter of 2000,20 and analysts expect this market sector to grow rapidly.21 A Web-based trading pit for the urban fiber that they provide now includes over 35 fiber wholesalers listing “over 10,000 local route miles” of fiber22 in more than 60 cities.23 For a growing number of CLECs, the fiber provided by these wholesale suppliers satisfies a large part of their demand for last-mile local connectivity and interoffice transport.

Resale markets have likewise developed for the provision of wireless services.24 As the Commission has noted, wireless resellers “offer service to consumers by purchasing airtime at wholesale rates from facilities-based providers and reselling it at retail prices.”25 According to the Commission’s Sixth CMRS Report, the top 20 resale providers had just over 3 million subscribers as of year-end 2000, twice as many as they did in 1999.26 Wireless carriers hammered out wholesale contracts among themselves years ago, to cover “roaming”; intercarrier roaming rates have been rapidly declining.27 And wireless carriers enter into wholesale deals with large corporate customers, too.28 At least 20 percent of businesses provide wireless services to their employees through deals they have negotiated with carriers to provide discounted rates for preset call volumes.29

A wholesale/resale market for broadband links is now beginning to emerge as well. GTE and AOL began open access trials in 1999, proving that “[c]able providers can easily and affordably open up their networks for high-speed Internet competition.”30 Many cable companies assert that open access will occur naturally, and that it is in both their best interest and that of consumers.31 And many have already entered into agreements to allow unaffiliated ISPs access to their networks.32

24 Early on, the Commission granted cellular A-side carriers certain rights to resell the B-side (i.e., typically incumbent wireline) carriers’ services, to maintain early competitive parity notwithstanding the head-start that the B- side carriers got in building out their networks. See 47 C.F.R. § 20.12 (b)(3).

4. Geographic Expansion

The Commission stated in the UNE Remand Order that “markets outside of major metropolitan areas . . . have seen minimal competition.”33 That is no longer the case today. CLECs are now using their facilities to serve markets of all sizes, throughout the country. For example, CLECs have obtained collocation arrangements to serve wire centers that contain more than 80 percent of the access lines in the Bell companies’ regions.34 And CLECs are using their own switches to serve customers in wire centers that contain approximately 86 percent of all lines in the Bell companies’ regions.35

Many CLECs have specifically targeted smaller markets, often precisely because the larger markets have already become saturated with facilities-based competition. Analysts have noted that “[i]n tier 2/3 markets, fundamentals are more favorable primarily due to less available capacity.”36 More than a dozen CLECs have adopted a strategy of specifically serving smaller markets (e.g., Tier II, Tier III, or Tier IV markets). See Table 3. In addition, many CLECs that serve larger markets, have expanded into smaller markets as well.37

Examples of CLECs That Have Specifically Targeted Smaller Markets Advanced TelCom Group Offers “bundled Internet, broadband data, and voice services to small and medium-sized businesses in third and fourth tier markets throughout the U.S.”; targets third and fourth tier cities with populations between 100,000 and 750,000 people and between 50,000 and 200,000 business access lines.” AFN Communications “AFN is targeting underserved markets . . . ‘We think this will clearly give them an opportunity to establish a beachhead. They are targeting a market opportunity that has gone untapped by the current crop of service providers.’” BayRing Communications “BayRing is a regional CLEC offering local, long distance, high-speed Internet service, and dedicated access to businesses in Tier 3 markets in New Hampshire and Maine.” Choice One Communications “Our company currently provides service to clients in 30 second and third-tier markets in eleven states where there are fewer competitors than in larger metropolitan areas.” Cinergy Communications “The focus for Cinergy Communications is toward small businesses in the region of Southern Indiana and Western Kentucky. Cinergy believes it can offer telecom services to areas that otherwise do not have many choices.” Volaris Online “DUROCOM is a full service, facilities-based provider of Internet data and (formerly DUROCOM) broadband communications solutions to consumers and small to medium-sized businesses in tier II and tier III markets in the southeastern United States.” e.spire Communications “e.spire’s establishment of footholds in ‘uncrowded’ Tier 2 and Tier 3 markets represented arguably the company’s most significant competitive advantage,” says Lizet Tirres, research analyst, Stratecast Partners. Crescent Telephone “‘Our proven track record in serving rural and suburban customers ideally positions Crescent Telephone to offer complete telecommunications solutions to markets historically underserved by traditional carriers,’ said Jacob Roquet, GIEX president and CEO, and founder of CoastalNet and Crescent.” KMC Telecom “KMC’s business has two distinct components: serving communications- intensive customers in markets with populations between 100,000 and 750,000, referred to as Tier III markets, which larger carriers have typically overlooked; and providing data services on a nationwide basis.” Knology Although CEO Rodger Johnson “admits his markets aren’t crowded with competitors, he says the idea that second and third tier markets are less competitive is a myth. ‘When you get down to markets with 100,000 [homes], you can’t divide that pie up more than about three ways and make it economically viable,’ he says.” LecStar Communications “LecStar focuses on underserved markets in the south… LecStar believes these secondary cities are relatively underserved.” Lightship Telecom “Lightship Telecom is targeting small to medium-sized businesses in Tier Two and Three markets.” NECLEC “NECLEC offers voice and data services primarily in Tier Two, Three, and Four cities in the Northeast/Mid-Atlantic region.” Sources: See Appendix M.

To be sure, facilities-based competition has inevitably emerged earlier in some markets, and later in others. States with larger concentrations of business customers38 are more attractive

to competitors.39 More rural states are more costly to serve.40 Regulatory differences have played a major role too. As noted earlier, some states have imposed wholesale rates on ILECs that artificially suppress the emergence of facilities-based competition.41 Some states opened their local markets to competition before the passage of the 1996 Act, and much earlier than some other states.42 Some states have set retail rates – particularly for residential customers – very low, which also discourages entry.43

B. The Failure of Non Facilities-Based Competition.

Since the last UNE review, many CLECs have attempted to enter local markets very rapidly, on a very large scale, by relying exclusively, or almost so, on UNEs obtained from ILECs. The Commission at one time suggested that these competitors would rely on UNEs only until such time as it “was practical and economically feasible to construct their own networks.”44 Many of these ostensible competitors, however, have adopted business strategies that do not involve deployment of their own facilities at any time in the foreseeable future. Investors have grasped that these business models offer little if any true value to customers. Many of the CLECs pursuing UNE-centric strategies have failed.

Carriers, 2000/2001 ed. at Table 2.4. New York, California, Texas, Illinois, and Ohio are home to the greatest number of Fortune 500 company headquarters – more than 200 companies, collectively. No Fortune 500 company has established its headquarters in 10 states (Alaska, Hawaii, Maine, Montana, New Hampshire, New Mexico, North Dakota, Vermont, West Virginia, and Wyoming). See Fortune 500 List, Cincinnati Enquirer (Apr. 2, 2001), http://enquirer.com/editions/2001/04/02/fin_fortune_500_list.html. 39 See, e.g., FCC, Biennial Regulatory Review 2000 – Staff Report, App. IV, Pt. 54, 15 FCC Rcd 21089, 21266 (2000) (“Competition for business customers in metropolitan areas has, in general, developed more rapidly than competition for residential customers or customers in rural areas.”); FCC Local Competition Report, Dec. 1998 ed. at 2 (“Facilities-based CLECs appear to have concentrated in more urbanized areas.”). 40 Rural populations vary widely between states, from a low of 10.6 percent in New Jersey in 1990, to a high of 67.8 percent in Vermont in 1990. See U.S. Census Bureau, Urban and Rural Population: 1900 to 1990 (Oct. 1995) http://www.census.gov/population/censusdata/urpop0090.txt. Under the FCC’s USF cost model, costs of providing service vary significantly (by as much as 50 percent of more) between highly rural and highly urban states. 41 See, e.g., James Eisner, FCC, & Dale Lehman, Fort Lewis College, Regulatory Behavior and Competitive Entry, for presentation at the 14th Annual Western Conference Center for Research in Regulated Industries, at 2 (June 28, 2001). 42 See, e.g., Implementation of the Local Competition Provisions in the Telecommunications Act of 1996, Notice of Proposed Rulemaking, 11 FCC Rcd 14171, ¶ 5 (1996) (“At the time the 1996 Act was signed, 19 states had in place some rules opening local exchange markets to competition, including seven states in which competing firms had already begun to offer switched local service.”). 43 See Sprint v. FCC, 274 F.3d 549 (D.C. Cir. 2001) (noting that one of the reasons put forward by the FCC’s counsel for low rates of competition in the residential market is that “state commissions have historically set relatively low residential rates . . . allowing the incumbent monopoly to make it up in other aspects of their business.”); R. Cowles, et al., Gartner Dataquest, UNEs: Stifling U.S. Broadband Growth and Ineffective in Promoting Local Competition at 7 (2002) (“Most states have frozen residential basic exchange rates at levels at or below cost. . . . it is the regulators themselves (state regulators and the FCC) that have created this regulatory barrier to competitive entry through a pricing policy that includes subsidy.”). 44 UNE Remand Order ¶ 6.

1. The Failure of UNE-Platform Competition.

The UNE Platform is “physically similar to resale. In each case, the CLEC uses the ILEC network to provide service to the end-user and essentially limits its own functions to marketing, inputting the order into the ILEC’s systems, and billing.”45 UNE-P requires no incremental investment by a CLEC, but – because of regulatory factors alone – it is generally cheaper than deploying facilities. With the exception of certain vertical features that no more than a few Platform-based CLECs actually provide, end-user customers do not receive any services on any facilities from a UNE-Platform provider that they would not also receive in the simple resale of the ILEC’s own service. UNE-P “competition” thus creates little if any opportunity for service differentiation. This competition is not value-added competition at all; it is defined not by expanding output, consumer choice, product quality, or market price, but by federal and state regulators and the TELRIC pricing regime.

As discussed in Section II.A.2, CLECs that rely on the UNE Platform argue that it provides a mechanism for CLECs to build up a customer base before they invest in facilities. But market experience since the time of the UNE Remand Order demonstrates that CLECs are not migrating UNE Platform customers to their own facilities to any significant degree (if at all). Many CLECs instead treat UNE-Platform competition as an end in itself, rather than as a stepping stone to facilities-based competition. These CLECs have obtained UNE Platforms to serve mass-market customers but have no plans to convert these customers to their own switches.46 Conversely, most of the CLECs that serve mass-market customers and that have deployed one or more switches of their own make little or no use of unbundled switching from the BOCs.47

The UNE-centric CLECs are not only failing to create any facilities-based competition of their own, they have harmed their facilities-based counterparts, too. Facilities-based CLECs recognize that the unrestricted availability of UNEs priced at a regulator’s estimation of long- term incremental cost can ruin a business making steep capital investments at here-and-now, real-world prices. As described above, these facilities-based CLECs view the availability of the full UNE Platform as particularly harmful to facilities based competition. See Table 1, supra.

2. The Failure of the DLEC Model.

“Data CLECs” or DLECs made a similar attempt to jumpstart ubiquitous competition, and were equally unsuccessful. Their business model centered exclusively on providing DSL services. Unlike the UNE-P competitors, the DLECs did typically deploy their own packet switches. But in the broadband market, most of the new value is in getting the broadband loop

itself up and running. That’s a difficult challenge on any medium, but an especially difficult one on copper, which wasn’t designed for broadband in the first place.48

The ILECs themselves have certainly found the deployment of DSL service to be a difficult and costly process49 – with all the resources at their command, it has taken ILECS more than three years to make the service available to just over 40 percent of the homes they serve.50 Once the infrastructure is ready for broadband service, it then takes between two and three years to break even on a new DSL customer.51 The DLECs simply ignored these engineering and economic realities. They cultivated the belief that DSL was easy and inexpensive to deploy.52 They promised to deploy broadband services faster and more efficiently than incumbent local telephone companies or cable operators.53

To grow quickly, the DLECs relied on a business model that centered around resale of the ILECs’ loops, with relatively little of the CLECs’ own facilities-based investment. In most of the central offices that they intended to serve, the DLECs planned to deploy only a single

Gerhardy, et al., Morgan Stanley, Dean Witter, Investext Rpt No. 2262978, Globespan: Initiating Coverage – Company Report at *12 (Aug. 17, 2000) (“While simple in theory, the deployment of high bandwidth services over infrastructures originally designed for simpler purposes has created significant challenges . . . .

However, new digital technologies that exploit the unutilized Telco bandwidth encounter problems from the legacy analog environment for which the infrastructure was designed.”). 49 See, e.g., P. Harvey, The Last Mile is a Rocky Road, Red Herring (Aug. 1, 2000) (“For DSL providers, one of the biggest hurdles has been the time and expense required to send a truck and technicians to each home that requests service.”); Infinilink Corp.

piece of equipment – a Digital Subscriber Line Access Multiplexer (DSLAM). DSLAMs vary in price depending on their capacity, but average “well under $200” per customer line – an investment of just $3 per month per line for each customer (conservatively assuming a five-year customer retention rate).54

The DLECs did not even intend to provide their own facilities-based connections to the Internet. Instead, they enlisted hundreds of Internet Service Providers to take charge of that end of things. The DLECs themselves acted merely as wholesale brokers – obtaining the loop from an ILEC on one side, and a connection to the Internet through an ISP on the other. The DLECs opted not even to attempt to offer voice services, which would have enabled them to collaborate and share facilities with their sibling voice CLECs.55 This strategy, the DLECs maintained, would let them grow very rapidly, on very small capital outlays.56

More than 20 DLECs began providing service between 1998 and the first quarter of 2000.57 Nine completed successful initial public offerings (IPOs), raising more than $1.3 billion in capital. The DLECs that went public had been in operation an average of less than 3 years; they had few lines in operation (an average of only 1,545); and they had a very limited cadre of employees (an average of 273). See Table 4. The companies themselves routinely admitted that

Then, between March and December 2000, the Internet bubble burst. The nine publicly traded DLECs lost more than 94 percent of their stock-market value. Industry insiders attributed this to the DLECs’ “unsound business models,” their failure to “own the physical layer,” and their decision to “run[] on another firm’s network.”60

The failed DLECs were eventually absorbed by more successful CLECs, often at a bargain price. AT&T and WorldCom acquired the two largest failed DLECs – NorthPoint and Rhythms; several other DLECs were likewise acquired by successful CLECs.61 Significantly, in

The deal was closed approximately one month in advance, resulting in a more than 20 percent reduction in acquisition cost.); AT&T News Release, AT&T Acquires Assets of NorthPoint Communications (Mar. 22, 2001) (AT&T acquired “substantially all of the assets of NorthPoint Communications” for approximately $135 million. “We are delighted to be acquiring NorthPoint’s DSL assets,” said Robert M. Aquilina, co-president of AT&T Consumer. “They will help us in our efforts to move aggressively to bring the full benefits of DSL to consumers and businesses. These benefits include high-speed Internet access, local and long distance calling, and exciting broadband services, including virtual private networks, among other possibilities, in the future.”); Cavalier Telephone Press Release, Cavalier Telephone Completes Purchase of Net2000 Communications V-17

some of these cases, the acquiring CLEC took only the assets of the failed DLEC – primarily collocation space – not its customers.62 If they had viewed “rapid” and “ubiquitous” entry as the keys to the competitive success, the acquiring companies would presumably have done just the opposite.

C. Anti-Competitive Impacts of Expanding UNEs into Competitive Markets.

While the unbundling regime was intended to promote competition for local exchange services,63 both interexchange carriers and wireless carriers have demanded that ILECs also unbundle the inputs used in the provision of long distance and wireless services. These complementary markets are already competitive in their own right. Extending unbundling into these markets is, therefore, not only unnecessary to assure continued competition in those markets, but also likely to undermine the competitive supply of facilities that already has emerged for the local inputs in these markets.

1. Conversion of Special Access Circuits to UNEs.

“Special access” is the name given to “a variety of services and facilities which constitute the local portion of certain interstate telecommunications lines.”64 Special access “primarily involves the provisioning of so-called ‘private lines,’ that is, facilities or network transmission capacity dedicated to the use of an individual customer.”65 These dedicated facilities typically “run directly between the end user and the [interexchange carrier’s] point of presence (POP),”66 or directly between two end-user locations. When ILECs provide special access circuits to interexchange carriers, the ILECs must typically build those circuits from the ground up, using a combination of local loops and interoffice transport.

The customers for special access “are IXCs and large businesses, not residential or small business end users.”67 In fact, between 78 and 89 percent of the special access revenue earned

The largest purchasers of special access service are interexchange carriers, which use special access to transport large volumes of traffic to and from their largest business customers.70 Between 56 and 76 percent of the special access revenue earned by BellSouth, Qwest, SBC, and Verizon is generated by interexchange carriers. The Commission has noted that long distance carriers “typically provide resold special access and private line services as part of toll service operations.”71

Special access traffic is also highly concentrated, geographically. In each of the BOC regions, the vast majority of special access revenue is generated in a very small minority of wire centers.72

The special access market is already highly competitive. It was among the first to be opened to competition, and it has attracted large numbers of competitors because of the extremely large traffic volumes that it involves. The only economic argument for permitting the

AT&T and WorldCom, for example, each has local facilities in approximately 100 markets that likely are used to provide special access services. See NPRG CLEC Report 2002, 15th ed., Ch. 6 – WorldCom at 13, 18 & AT&T at 19, 24. Sprint has stated that it is deploying local fiber rings in “20 major U.S. markets” that allow “improved access economics,” and enable Sprint “to significantly reduce its special access costs.” Sprint News Release, Sprint Announces Financial Targets and Growth Strategies (Nov. 3, 2000). Other long distance providers – including Williams, Level 3, and Global Crossing – likewise have extensive local facilities that they use to self-provide special access services. See, e.g., C. Grice, Williams to Expand High-Speed Network into 50 Cities, News.com (Feb. 10, 2000), http://news.cnet.com/news/0-1004-200-1546995.html?tag=st (Williams “expects to spend $421 million over three years in order to link its proposed 33,000-mile fiber-optic ‘backbone’ network directly to business customers in the nation’s largest cities.”); Level 3 Communications, The Level 3 Network, http://www.level3.com/673.html (Level 3 has 57 markets in service and almost 16,000 miles of conduit in North America); Global Crossing Press Release, Global Crossing Reports 2000 Pro Forma Cash Revenue up 36%, Recurring Adjusted EBITDA up 54% from 1999 (Feb. 14, 2001) (in 2000, Global Crossing completed metro rings in 10 cities in the United States: New York, Philadelphia, Washington D.C., Atlanta, Miami, Dallas, Chicago, San Francisco, San Jose, and Los Angeles). 71 FCC, Local Telephone Competition at the New Millennium at Table 6, note **** (Aug. 2000). 72 More than 80 percent of SBC’s special access revenues are generated in less than 25 percent of the wire centers in which it is providing special access.

In Qwest’s region, more than 60 percent of special access revenues are generated from 11 percent of Qwest’s total wire centers.

conversion of special access circuits into UNEs is that it would supposedly reduce the costs of the inputs that interexchange carriers use in the provision of long distance services. But as the Commission has recognized, the long distance market already is competitive for large business customers that are the primary end-users served with special access circuits.73 Any regulatory action that merely reduces the prices that one of the competitive suppliers of special access may charge is, therefore, unnecessary to promote long distance competition.

Any such action would devalue the assets of other competitive suppliers in this market. CLECs as a group are more significant suppliers of special access service than basic local exchange service. As the Commission has found, “the revenues of competitive LECs come primarily from special access and local private line services.”74 CLECs now account for between 28 and 39 percent of all special access revenue, see Appendix L, which is significantly larger than their share of the local exchange market as a whole.75 CLECs have obtained fiber- based collocation in wire centers that contain a significant share of BOC special access revenues.76

2. Conversion of Transmission Services for Wireless Carriers.

Some wireless carriers suggest that CMRS base stations are equivalent to ILEC end offices, and that wireless carriers are therefore entitled to buy “interoffice transport,” at UNE rates, between various points on their networks.

Wireless carriers clearly do not need access to transport UNEs to compete in wireless markets themselves. The 1996 Act authorized ILEC wireless affiliates to enter long-distance markets immediately, without waiting for any unbundling or section 271 checklist approval by their wireline affiliates.77 As the Commission’s sixth annual report (“Sixth CMRS Report”) on competition in Commercial Mobile Radio Services (CMRS) concluded in December 2001, U.S. wireless markets are robustly competitive, and growing more so year by year.78 While ILEC

In 154 of these MSAs, one or more collocation arrangements exist in wire centers that cover at least 65 percent of the incumbent LEC’s special access revenues in those MSAs.). 77 47 U.S.C. § 271(g)(3). 78 See, e.g., Sixth CMRS Report 4-5 (“In the year 2000, the CMRS industry continued to experience increased competition and innovation as evidenced by lower prices for consumers and increased diversity of service offerings.”). The Commission cited that the “continued downward price trends, churn, and continued expansion of mobile networks

affiliates rank as robust competitors in wireless markets, unaffiliated wireless carriers are more than holding their own. Approximately 40 percent of the wireless market is served by carriers that are not affiliated with any ILEC.79

Wireless networks consist of four basic tiers. See Figure 4.80 The first three tiers define the wireless tier of the wireless carrier’s network; the fourth tier both switches wireless calls and hands them off to and from the wireline network.81 All of the true switching is performed at the fourth level.

The base station is not a switch – its purpose is to allocate a shared resource – wireless bandwidth – among multiple users of the network who aren’t all using their wireless phones at the same time. It is the mobile switching center – not the base station itself – that orchestrates the intra-switch hand off when a user moves away from base station A and toward base station B. And likewise for the hand-off required when the user moves on toward a more distant base station C, which is connected to an entirely different switch. The switches themselves are linked to an ATM network that is there to support these “soft,” inter-switch handoffs of live calls. The base station plays no more role in orchestrating the hand off than the wireless handset does – all of these tiers of the network remain under the direction and control of the switch. And in any

into new and existing markets demonstrate a high level of competition for mobile telephony customers. . . . Most carriers report churn rates between 1.5 percent and 3 percent per month. . . . According to one recent survey, almost one in five wireless subscribers have switched carriers in the past year.” Sixth CMRS Report at 21, 23. 79 See Legg Mason Wireless Industry Scorecard at Exh. 8 (estimated market share as of 3Q 2001). 80 See Nortel Networks, Products and Services, CDMA Networks, http://www.nortelnetworks.com/products/ 01/cdma/index.html#. 81 See Nortel Networks, The DMS-100 Wireless System at 3, Document No. 50171.16/10-97 Issue 1.

event, the hand-offs themselves are not equivalent to switching; they occur to support efficient use of radio spectrum in a cellular architecture network, not the routing of calls between end- users.

3. Conversion of Broadband Services for Information Service Providers.

The provision of information services is highly competitive, and has been deregulated for more than 30 years. While information services providers sometimes use parts of the local exchange network to provide service to end users, they do so by obtaining tariffed services from ILECs. The 1996 Act makes clear that UNEs cannot be used to provide an information service.82

CLECs have nonetheless attempted to insert themselves between ILECs and information services providers by converting tariffed customer services into UNE-centered services. Various CLECs have obtained UNEs to provide connections between end-user customers and those customers’ ISPs. This is what data CLECs like Covad do with respect to broadband Internet access. The CLEC in this scenario is typically little more than a regulatory fiction – a device to use a particular regulatory classification to obtain UNE-based “carrier” connections and prices lower than those available to mere “customers.” The CLEC adds little if any value of its own.

The extension of UNEs into the information services realm is surely not necessary to promote competition for these services. Competition has evolved rapidly without such UNEs. For example, there are now more than 7,000 providers of narrowband Internet access, and the Bell companies collectively provide service to fewer than 6 percent of the subscribers to these services.83 Nor is the extension of UNEs to serve ISPs necessary to promote competition in the broadband market. As discussed in Section IV.C, the provision of broadband services is already highly competitive.

D. Facilities-Based Investment in New Broadband Infrastructure.

The “widespread deployment of broadband infrastructure has become the central communications policy objective of the day.” This will require “the complete or near-complete replacement of copper lines with end-to-end fiber optic transmission facilities.”84 To promote the objective, “broadband services should exist in a minimal regulatory environment that promotes investment and innovation in a competitive market.”85

Manufacturers of computers and other types of hardware that use bandwidth are all but unanimous in their view that – as Intel CEO Craig Barrett puts it, “broadband” only “gets exciting when you get to 5 megabits per second or even 100 mbps.”86 What ranks as

82 See 47 U.S.C. § 251(c)(3). 83 See P. Fusco, Top U.S. ISPs by Subscriber: 2001 Year End, ISP-Planet.com (Feb. 11, 2002), http://www.isp-planet.com/research/rankings/usa.html. 84 Appropriate Framework for Broadband Access to the Internet over Wireline Facilities, Notice of Proposed Rulemaking, 17 FCC Rcd 3019, ¶¶ 1, 12 (2002). 85 Id. ¶ 5. 86 J. Shiver, Intel CEO Makes Case for Broadband Aid, L.A. Times (Jan. 28, 2002).

“broadband” today “is not sufficient to provide some of the serious content people are interested in.”87 Surveys already confirm that consumers who obtain broadband connections use the Internet more, not less.88 Higher speed connections don’t merely accelerate – and thus shorten – connections – they immediately lead to new uses and thus, longer connections.89 As the Commission recognized in its First Advanced Services Report, broadband links become part of a self-reinforcing “virtuous cycle,” in which better performance and lower per-bit price “fuels more demand” – heavier use of existing applications, and, more importantly, “demand for new applications that were not feasible before.”90 “As the cycle gains momentum . . . companies will provide new applications and services for broadband consumers, . . . consumers will demand broadband, and the virtuous cycle will accelerate.”91 See Table 5.

87 Id. As Intel has stressed, “the true benefits of broadband will require faster transmission speeds” – “at only 200 kbps, ‘advanced services’ are not capable of providing adequate transmission speeds for video.” Comments of Intel Corp. at 5, Inquiry Concerning the Deployment of Advanced Telecommunications Capability to All Americans in a Reasonable and Timely Fashion, and Possible Steps to Accelerate Such Deployment Pursuant to Section 706 of the Telecommunications Act of 1996, CC Docket No. 98-146 (FCC filed Sept. 24, 2001). “High-definition video requires 19.8 Mbps; DVD-quality video needs almost 4 Mbps; and even television quality requires 750 kbps or more. In fact, ‘many experts set 100 Mbps as the frontier [of the Web’s true potential for] general surfing to streaming high-quality, skip-free digital audio and video, as well as faster upload of graphic images and larger files.’” Id. Corning likewise has suggested that “[a] minimum transmission speed of 10 mbps upstream and downstream should be utilized for the purpose of defining next generation broadband capability. . . . This speed is necessary to allow for the bi-directional transmission of audio, data at 10 base-T Ethernet speeds, and compressed full motion video.” Comments of Corning Inc., Deployment of Broadband Networks and Advanced Telecommunications, Docket No. 011109273-1273-01 (NTIA filed Dec. 19, 2001). But Corning stressed that “10 mbps is a minimal level of transmission,” that the range really extends from 10 mbps to 1 Gbps. Id. Corning senior vice president Timothy Reagan told the House Energy and Commerce Committee that “[i]f you think that Americans will need access to information in all its forms – audio, video, and data – it is easy . . . to see that a capability in excess of 22 [Mbps] downstream and 10 [Mbps] upstream is ideal.” Timothy Regan, Senior Vice President, Corning Inc., prepared witness testimony before the House Energy and Commerce Committee, Washington, D.C. (Apr. 25, 2001). 88 See, e.g., Broadband 2001 at Charts 16 and 17 (as broadband users, survey participants spent on average 21.4 hours per month online, as compared to 15.9 hours with a narrowband connection. These same users also spent more time per session (32 minutes vs. 21 minutes), spent more days online (18 vs. 17) and viewed more pages per month (1,828 vs. 1,561)); Jupiter Media Metrix Press Release, Over 40 Percent of US Online Households to Connect Via Broadband by 2006, Reports Jupiter Media Metrix (Oct. 17, 2001) (“Broadband consumers continue to use their connections more intensively than narrowband consumers do…”). 89 According to a Broadband Watch study, customers are using broadband to engage in online activities such as shopping online (95 percent), e-mailing photos (76 percent), downloading streaming video (64 percent), downloading MP3s (61 percent), telecommuting (60 percent), creating Web pages (49 percent) and playing games (47 percent). Respondents also reported that with DSL, they are much more likely to engage in these higher-bandwidth activities: downloading MP3s: 61 percent with DSL vs. 35 percent with dial-up; downloading video: 64 percent with DSL vs. 36 percent with dial-up; and e-mailing photos: 76 percent with DSL vs. 62 percent with dial-up.

From the consumer’s perspective, demand for bandwidth – raw digital capacity and speed – has been rising very fast for the last decade – just as demand for speed and capacity in all the hardware that links up to the digital networks as been rising inexorably for the past two decades. See Figures 5 & 6. What ranks as “broad” today no longer will a few years hence. Most of the applications that will generate data traffic five years hence aren’t running today, at least not in any way comparable to what they will become. Most of the users of “broadband services” today aren’t yet using those services for what they will be using them for in the fairly near future. Most of today’s “broadband” infrastructure, both wired and wireless, will have to be upgraded again and again, indefinitely into the future, to meet the continuous rise in demand.

Many residential applications are now emerging, from high-speed games to telecommuting to telemedicine, that will push residential consumers toward symmetric broadband services. As the chief of the Commission’s Media Bureau recently observed, “current generation ‘broadband’ networks cannot support . . . killer apps, the predecessors of which are

V-25

staring us right in the face.”92 Such applications will require “next generation of broadband network – one that presumably will be symmetrical, or nearly so, and capable of delivering perhaps ten megabits per second.”93

As the Commission itself recently concluded, much of the copper distribution plant will have to be replaced with fiber.94 One analyst estimates that “modernizing our wireline access infrastructure will likely cost over $200 billion from start to finish,” and that this investment will have to be made “without a firm grasp of what services will be demanded and at what price they will be purchased.”95

Wireless broadband services are coming, too. A number of U.S. CMRS carriers have already deployed 2.5G96 services which allow users to access the Internet at speeds up to 144 kbps, a significant improvement over widely deployed 2G services, with top speeds around 10 kbps.97 3G networks will be needed for true broadband.98 Although the FCC has yet to allocate additional spectrum specifically for 3G wireless services, a number of companies already are in the process of deploying 3G networks over their existing spectrum. Verizon Wireless recently launched its 3G service in markets covering one-third of the company’s national footprint.99

Sprint PCS is expected to follow within the first half of 2002.100 Analysts predict that 3G networks will be widely deployed by 2004 or 2005.101

The Commission also has recently taken the first steps to “pave the way for new types of products incorporating ultra-wideband (UWB) technology” 102 – devices that “can operate using spectrum occupied by existing radio services without causing interference,”103 and to explore the introduction of “software defined radio” (SDR) technology that could allow a single device to be quickly reprogrammed to transmit and receive on any frequency within a wide range using virtually any transmission format.104 There also are a host of other technologies currently under development that will be capable of provisioning wireless broadband services. These include Digital SMR, 2 GHz MSS satellite systems, L-Band satellites, and Big LEO satellites.

The strongest incentive 3G carriers and other wireless carriers have today to accelerate the roll out of their broadband wireless services is to capture from incumbent cable operators and ILECs a share of the profitable ($40-$50 per month) broadband subscription fees. A UNE policy that promotes uneconomic competition over the high-frequency portion of the ILEC loop, based on excessively discounted TELRIC prices, will surely depress investment in the high-frequency portions of the airwaves themselves.

Finally, the Commission has recognized that fixed wireless access offers “a replacement for the ‘last mile’ of copper wire.”105 Recent advancements in fixed wireless technologies are expected to “cause a spur in service provider deployments.”106 In particular, Non-Line-of-Sight

technologies have been developed, which obviates the need for an unobstructed path between a fixed wireless transmitter and an end-user premises.107 In addition, “[t]he incorporation of IP- based telephony capabilities in second-generation NLOS equipment will allow MMDS providers to incorporate voice applications in their service mix.”108 This is expected to prompt fixed wireless providers “to target the residential end users, thereby increasing fixed wireless availability and hence subscriber base.”109

The Commission also has recognized that the new broadband infrastructure, both wired and wireless, will be rolled out incrementally. Network deployments are “complex and time- consuming projects that require enormous capital expenditures, a skilled labor-force, and available supply of advanced equipment.”110 As a result, even incumbent network operators “cannot upgrade all of their systems simultaneously,” but instead “upgrades are a multiyear and multiphase endeavor, whereby the operator upgrades certain systems and offers new services on an incremental basis.”111 See, e.g., Figure 7.

Unfettered competition is almost always the best policy when markets are young, and when technology is evolving quickly.112 And that is certainly the condition of the broadband market today. Most of the market is up for grabs, because 90-plus percent of the technology that will ultimately be used hasn’t yet been built, 90-plus percent of the capital hasn’t yet been committed, and 90-plus percent of the customers aren’t yet being served. And because broadband digital services will ultimately absorb and displace the old, analog voice and video, it is equally true that no player in the market today has any assurance of winning any given share of the vast digital market ahead. An extraordinary transformation in technology is overtaking all the old certainties.

112 See, e.g., Michael Powell, Chairman, FCC, remarks before the National Summit on Broadband Deployment, Washington, D.C. (Oct. 25, 2001) (“The market is the best vehicle designed by mankind for innovation, for technology change and evolution.”); id. (“Clearly, legal restraints can retard deployment of new services.”); Michael Powell, Chairman, FCC, remarks before the Federal Communications Bar Association, Washington, D.C. (June 21, 2001) (“[B]efore 1993, many argued that we should not open up the wireless market. It was thought that two competitors in the cellular market were certainly more than sufficient. Since that market was opened and PCS introduced we have seen a phenomenal explosion in innovative, digital wireless services.”).

APPENDIX A. ESTIMATING CLEC LINES

The FCC’s February 2002 Local Telephone Competition Report includes CLEC line- count figures that are based on counts supplied by the CLECs themselves to the FCC. Those counts do not appear to be accurate, however. There are other significant problems too, but the most important source of inaccuracy is probably that CLECs are either overlooking or misinterpreting the requirement that they convert high-capacity lines into voice-grade-equivalent lines. In contrast, the CLECs do make a clear distinction between lines and “voice-grade equivalents” when they report on the state of their business to investors.

According to the Commission’s recent report, CLECs reported serving a total of 17.3 million lines as of June 30, 2001. The CLECs inform the FCC that they served about half of those lines – 8.6 million lines – in whole or in part over their own facilities, beginning with their own switches.1 The other half were resale or UNE-P lines, switched by the ILEC.

The Bell companies are, of course, in a position to check the UNE-P and resale-line totals directly, and Bell company records confirm that the CLECs’ resale and UNE-P counts are reasonably accurate. But additional Bell company records indicate beyond serious doubt that the estimates of facilities-based lines that the CLECs are supplying to the Commission are much too low. CLECs are in fact serving two to three times as many lines over their own facilities than their reports to the Commission indicate. In total, CLECs served no fewer than 25 million lines, and likely closer to 32 million lines as of year-end 2001, not 17 million.

“Lines” versus “Voice-Grade Equivalent Lines.” The FCC directs CLECs to report “all local exchange service lines and all lines that are used for exchange access services.”2 Carriers must report all “voice-grade equivalent lines,” which are defined as “a line or channel that directly connects an end user to a carrier and allows the end user to originate and terminate local telephone calls on the public switched network.”3 The FCC further directs carriers to:

Count as one voice-grade equivalent line: traditional analog POTS lines, Centrex- CO extensions, and Centrex-CU trunks. Count lines based on how they are charged to the customer rather than how they are physically provisioned . . . Report 8 voice-grade equivalent lines if a customer buys 8 trunks that happen to be provisioned over a DS1 circuit. If a customer buys a DS1 circuit that is

1 CLECs reported serving 5.8 million lines over “CLEC-owned ‘last-mile’ facilities.” FCC Local Competition Report, Feb. 2002 ed. at Table 3. In addition, CLECs reported serving 7.6 million lines through “UNEs,” which includes UNE loops leased from an ILEC and used in combination with a CLEC’s own switch. See id. at 1-2 & nn. 3-4. According to data reported by ILECs, there were 4.8 million “UNEs with switching” provided to CLECs. See id. at Table 4. Subtracting this figure from the 7.6 million lines that CLECs serve through UNES, results in 2.8 million CLEC lines served using ILEC loops but CLEC switching. 2 FCC, Instructions for the Local Competition and Broadband Reporting Form, FCC Form 477 at 5 (of data as of Dec. 31, 2001) (“Form 477 Instructions”). 3 Id. at 5, 6 (emphasis in original).

provided as a channelized service, report 24 voice-grade lines, even if there is some indication that the customer is only using 8 of the derived lines.4

CLECs certainly know what the term “voice-grade equivalent line” means. They use the term themselves in reports to the investment community, including their reports filed with the Securities Exchange Commission. See Section I, Table 4. In dealing with the FCC, however, some CLECs express concern that complying with the FCC’s instructions would lead to the release of competitively sensitive information.5 As the Commission itself has noted, “the reports of at least some CLECs are not consistent” with its directions, and, as a result, “there may be some need for further clarification and adjustment of the reporting system.”6

E911 Listings: At Least 16 Million Facilities-Based CLEC Lines. As of year-end 2001, CLECs had listed 16 million lines in E911 databases – or almost twice as many as the 8.6 million facilities-based lines they reported to the FCC. This gross discrepancy cannot be attributed to any factor other than gross under-reporting by the CLECs to the FCC.7

For obvious reasons, the E911 databases are maintained with scrupulous care. The databases are maintained on behalf of police and fire departments by the ILECs; their contents are derived from both ILEC and CLEC records. ILECs provide all entries for lines served by the ILECs themselves, and for UNE-P and resale lines served by CLECs. CLECs provide the entries for lines switched by CLEC switches. Once a carrier loses a customer, its E911 listing for that customer is replaced by the listing of the customer’s new carrier, which ensures that the database does not become infected with large numbers of obsolete listings.

Each E911 subscriber listing represents at least one customer access line, but may represent more than a single line. In the case of business customers, for example, a single E911 listing may represent many individual lines, because a carrier does not typically have to create a separate E911 listings for every line served at the same location. A business might, for example, have 100 lines numbered 326-79xx; a single E911 listing would then suffice to link all calls from 326-79xx numbers as originating from the same location. A count of CLEC lines based of E911 listings will therefore understate the number of lines served by CLEC switches.

4 Id. 5 See, e.g., Comments of AT&T Corp. at 17, Local Competition and Broadband Reporting, CC Docket No. 99-301 (FCC filed Dec. 3, 1999) (“There is little information that is guarded more closely by a newly-developing competitor . . . than its subscriber and access line counts.”); Comments of Time Warner Telecom at 6-7, Local Competition and Broadband Reporting, CC Docket No. 99-301 (FCC filed Mar. 19, 2001) (“Much of the data the Commission requests on Form 477 is widely considered proprietary and competitively-sensitive. . . . [f]or example, TWTC routinely seeks confidential treatment of its data on total voice telephone service lines and channels provided to end users.”). 6 FCC Local Competition Report, Feb. 2002 ed. at 1-2, n.3. 7 The CLEC-reported totals in the FCC’s report are understated for other reasons as well. The FCC requires CLECs to provide the number of lines they serve on a state-by-state basis, but only for the states “in which they provide 10,000 or more ‘voice-grade equivalent lines.’” Form 477 Instructions at 1. As the Commission has recognized, “lines as reported by CLECs are understated as a result of th[is] state-specific reporting threshold.” FCC Local Competition Report, Feb. 2002 ed. at 2, n.5. Any confusion with regard to lines versus “voice-grade-equivalent circuits” may of course seriously compound this under-reporting problem. Moreover, the FCC totals are as of June 2001, whereas the totals reported here are for year-end 2001.

A-2

Both the FCC and the Department of Justice have repeatedly relied on E911 listings to estimate CLEC facilities-based lines in section 271 proceedings.8 No CLEC providing service to end-user customers has yet claimed that its facilities-based lines are actually lower than the totals produced by its E911 listings.9 Nor has any CLEC disputed that the E911 methodology undercounts lines served.

Interconnection Trunks: 23 Million Facilities-Based CLEC Lines. CLECs have obtained approximately 9 million interconnection trunks from ILECs. In the reports they file with the FCC, however, the CLECs claim to be serving only 8.6 million lines over their own facilities. It is simply inconceivable that CLECs have obtained roughly one trunk for every line they serve.

CLECs serve a large number of residential and business customers for whom line-to- trunk ratios of between 4:1 and 10:1 are the industry norm. In arriving at the high-end estimate – 23 million facilities-based CLEC lines – presented in this report, the Bell companies used a ratio of 2.75 lines per interconnection trunk. That ratio is based on internal studies that one Bell company (SBC) performed in 1998. That study took a weighted average of the different kinds of customers that CLECs were likely to be serving at that time, and the line-to-trunk ratios they were likely to be using for those different types of customers. The study assumed that 65 percent of CLEC lines were provided to ISPs using a 1:1 line-to-trunk ratio, and that the remaining 35 percent were provided to business customers using a 6:1 line-to-trunk ratio.

Today, CLECs are serving a far higher percentage of non-ISP customers.10 Their average line-to-trunk ratios will therefore be considerably higher today than they were in 1998. Larger CLECs will have higher line-to-trunk ratios too, because large-number statistics make possible much more efficient sharing of trunks. And CLECs are much less likely to maintain inventories of inactive trunks today than they were in 1998. CLEC operations have grown much more efficient over time, and CLECs are now less likely to base day-to-day business decisions on over-optimistic projections of future growth.

For all of these reasons, our trunk-derived estimates of 23-million facilities-based CLEC lines are very conservative. As with the E911-derived estimates, the actual totals may well be two to ten times higher.

8 See, e.g., DOJ Arkansas/Missouri Evaluation at 4, n. 8 (“Estimated market share will vary depending on the methodology used to estimate facilities-based lines. The Department relied on entries in the E-911 database.”); DOJ New York Evaluation at 9; DOJ Kansas/Oklahoma Evaluation at 4, n. 11 & 7, n. 25; DOJ Massachusetts Evaluation at 4; DOJ Pennsylvania Evaluation at 4. 9 On a few occasions (e.g., Sprint in the first Georgia/Louisiana 271 proceeding and WorldCom in the Arkansas/Missouri 271 proceeding), CLECs have claimed that their residential E911 listings were only for test lines, not actual customers, and that they were no longer operating those test lines. While E911 listings are typically removed from the database when a customer modifies or terminates service on a given telephone number (e.g., when the customer switches to another carrier, or the customer’s phone number is transferred to a different address), at any given time a snapshot of the E911 database is taken there may still a few inactive E911 listings in the database. Such listings represent no more than a de minimis fraction of all CLEC listings in the database at any given time. 10 For example, based on E911 listings, CLECs serve approximately 3 million residential subscribers today over their own local switches, which represents between 13 and 19 percent of all lines that CLECs serve with their own switches.

CLEC Reports to Investors: 156 Million Voice-Grade Equivalent Lines. Twelve CLECs publicly report the numbers of “voice-grade” “DS0” or “access line” “equivalents” they serve. Together they report serving a total of 156 million voice-grade circuits. See Section I, Table 4. In a recent presentation to Lehman Brothers, AT&T President David Dorman stated that AT&T’s local network alone was being used to serve “2.7 M local voice lines,” but “over 30 M DSO equivalents.”11 WorldCom’s most recent 10-K filed with the SEC indicates that it added more than 10 million “domestic local voice grade equivalents” in 2001 alone, bringing its total to more than 76 million.12

APPENDIX B. CLEC CIRCUIT SWITCHES

This appendix tabulates the circuit switches that CLECs operate. It is based on information contained in Telcordia’s Local Exchange Routing Guide.

This appendix includes the switches owned by CLECs that have declared bankruptcy. Most such CLECs are still operational (and some are now emerging from bankruptcy). Moreover, switches are a sunk investment, so if one company ceases to use its switch it is highly likely that another company will quickly seize the opportunity to do so (and will probably be able to obtain the switch at a fire-sale price). In addition, even though some CLECs may now be experiencing financial troubles, the fact that they were able to deploy so many switches at one time is still highly probative of the ability of CLECs to deploy switches generally. In any event, switches operated by CLECs that have declared bankruptcy (as of March 31, 2002) represent no more than 17 percent of the total counted here.

APPENDIX E. CLEC PACKET SWITCHES

This appendix tabulates the packet switches that CLECs operate. It is based on information from New Paradigm Resource Group’s CLEC Report 2002.

This appendix includes the switches owned by CLECs that have declared bankruptcy. Most such CLECs are still operational (and some are now emerging from bankruptcy). Moreover, switches are a sunk investment, so if one company ceases to use its switch it is highly likely that another company will quickly seize the opportunity to do so (and will probably be able to obtain the switch at a fire-sale price). In addition, even though some CLECs may now be experiencing financial troubles, the fact that they were able to deploy so many switches at one time is still highly probative of the ability of CLECs to deploy switches generally. In any event, switches operated by CLECs that have declared bankruptcy (as of March 31, 2002) represent no more than 19 percent of the total counted here.

APPENDIX J. ADDITIONAL INFORMATION ON SOFTSWITCHES

Table 1. Features of Packet Switches/Softswitches vs. Traditional Circuit Switches Less fixed • “Currently a Softswitch costs 40% to 45% less than an equivalent circuit switch.” investment • “Originally envisioned to replace the monstrous Class 5 switches, softswitch platforms, by recent estimates, can be as much as 20 times smaller physically and 10 times cheaper.” • CLEC DixieNet “found that for ’10 percent’ of the cost of traditional class 5 equipment, it could accomplish everything the firm intended to do with a switch through softswitch technology.” • TelePacific Communications: “With the new convergent systems, we will be able to move into new service areas in weeks rather than months and add new services instantly rather than wait for months for vendors to enhance their switches.” Less expensive • “Carrying voice traffic on a packet platform saves up to 70% in operating costs, by [Banc of America] estimates.” to operate and • “In addition to providing its customers with 10-25 percent cost reductions on local voice service, the new architecture maintain provides CTC with higher margins – about 50 percent, versus the 10-30 percent margin afforded by CTC’s former resale business.” • “New business models based on the use of IP-oriented switches have an infinitely better value proposition for carriers. . . . They’ll enable gross margins in the 60 percent-plus range and the ability to provide differentiated offerings.” • DixieNet: “Other switch-related expenses – operation, maintenance, power, air conditioning, vendor support, training expenses, the cost of upgrades – all the costs were significantly lower with the softswitch system.” • BroadRiver: “you get all the functionality of a basic class 5 type of switch in about a tenth the floor space for about a third the power. ” • “A majority of the cost savings is derived from Sonus’ dramatically smaller footprint. A circuit-switched network requires roughly 40 bays of equipment to simultaneously switch 50,000 calls. Sonus’ packet-based platform is capable of switching the same number of calls with just two 19-inch racks of equipment.” Reduced • WorldCom: these new switches “provides input for IP, frame relay, ATM and voice all in a single box. We no longer have peripheral the need of putting out an IP router, an ATM switch, a frame relay switch and a voice switch. We do it all with the Multi- equipment Services Switch. We can get a capital reduction because of a single box versus many boxes. And secondly, we get a needs trunking efficiency because now we only have to trunk back one box versus multiple boxes. That capital efficiency improvement is anywhere from 50-75%.” Increased • Allegiance: “The traditional switch with its time-space-time architecture is constrained. By deploying networks of media scalability gateways which use standardized packets, new more-scalable networks are possible.” • XO: Softswitch technology will allow XO to realize cost savings both in reduced equipment cost and reduced physical co- location space needs. Additionally, softswitches are expected to be quickly scaleable and have capabilities to launch new and enhanced services. Increased • “Network intelligence in data networks offers carriers opportunities to offer differentiated, value-added enhanced services flexibility for regardless of transport method.” new services • Electric Lightwave: “Another key concept in the softswitch model is the ability to quickly provide new services and applications.” • “Softswitches have greater flexibility. Legacy switches . . . contain a lot of proprietary code, whereas softswitches are easier to customize, enabling service providers to develop a wider variety of services and create new revenue streams.” High quality • “With technologies currently available, it is possible to obtain quality voice calls over dedicated IP data networks.” and reliability • “Because it is truly a Central Office in a single system, the FUSION 5000 passed all platform tests with flying colors in the first attempt and is approved for general deployment in service provider central offices throughout the country.”) • “Now soft switches like that of Lucent can do between 144,000 and 5.25 million busy-hour call attempts, which is in the neighborhood of what a PSTN Class 5 can do.” • BroadRiver: “‘I would even say that the flexibility associated with this type of approach and technique gives you better survivability and reliability . . . The flexibility in terms of being able to dynamically switch and route traffic . . . is very open and very flexible,’ Buttermore said. ‘From a problem-resolution perspective, that’s great.’” Sources: See Appendix M.

Table 2. The Emergence of Softswitches

• “At first used only for limited functions, in the past 12 months, softswitches have emerged as a possible alternative to the traditional class 5 devices at a number of small carriers.” • “[I]t is fair to say that CLECs are about to graduate from Class 5 to a new generation of multiservice platforms-capable of carrying Internet protocol (IP) and circuit-switched traffic and consolidating functions that previously were supported in separate, standalone devices.” • “Nobody doubts that the new switches will eventually overtake the current products. . . . ‘The benefits that the new switches offer are so enticing that all carriers eventually will incorporate them in their networks.’” • “a CLEC today is unlikely to buy a Class 5 switch for a new buildout in a city . . . and will likely go with a softswitch solution.” • “Only a few short years ago, any company that wanted to get into the facilities-based telecom market had only one choice: The heavy, expensive, inflexible and complex class 5 switch, the technology that has driven telecommunications for decades. . . . In the past few years, a new option has emerged. It’s less expensive, more capable of adding new features, much smaller and easier to run: The humble softswitch.” Sources: See Appendix M.

Table 3. CLECs Deploying Softswitches CLEC Softswitch Deployment Allegiance “announced today the official deployment of softswitch technology as a complement to its existing network infrastructure. . . . will now be able to utilize packet switching - in addition to the traditional circuit-switched technology already deployed in its 21 U.S. markets.” Broadriver “using Cisco BTS 10200 softswitches and 2400 series integrated access devices (IADs) . . . launched VOIP-based converged voice, data and Internet service in Atlanta, Nashville and Orlando, and announced plans to expand service into Charlotte, Ft. Lauderdale, Miami and St. Petersburg by year’s end.” Tom Buttermore, CEO of Alpharetta, Ga-based competitive-communications firm BroadRiver Communications, said the advent of softswitches was the main reason his company was formed. CTC Communications “By introducing softswitch technology into its network, CTC will only lease T1 (1.5-megabit-per- second) loops from the incumbents, providing the intelligence for basic and enhanced voice services on its own.” CTC “built its own facilities-based network, without installing any circuit switches, in 1999,” but instead has used a combination of softswitches and ATM switches. Global NAPs Global NAPS has reportedly “gone so far as to deactivate four class 5 switches and deploy 35 softswitches, with 40 more in the pipeline as substitutes.” KMC Telecom “Lucent’s Softswitch IPO allows us to protect our switching infrastructure, save on real estate and reduce expenses without deploying costly circuit switches. . . . Now, we can deploy more telecom ports per square foot in a cost-effective manner.” Level 3 “By deploying Sonus’ IP technologies into our network, we can deliver new services more rapidly and cost-effectively than we could before.” NewSouth “Tekelec’s softswitch will provide long-distance service to NewSouth’s customers in a nine-state Communications coverage area.” Time Warner Telecom “has deployed Sonus’ packet telephony product family, including softswitches and media gateways, in eight markets throughout the United States . . . [and] is now delivering revenue- generating traffic over those networks.” USA Datanet “selected the Sonus Packet Telephony suite, including the . . . PSX6000 SoftSwitch . . . as the platform for its next-generation VoIP network.” WorldCom “WorldCom is taking the softswitch route and will deploy six of the devices by year-end [2001] . . . The new switches handle dial-up Internet traffic more cost-effectively than traditional Class 5 switches and have the capability to do voice over IP.” XO Communications “plans to use the Sonus Networks platform, which includes . . . the PSX6000 SoftSwitch . . . The system is expected to act as an integral piece of XO’s future network foundation, and will support a full range of local, long distance and Internet services to enterprise customers.” Kancharla “VocalData Inc., a leader in the service delivery softswitch market, today announced that Kancharla Corp., a leading competitive local exchange carrier based in Huntsville, Ala., has purchased and deployed VocalData's award-winning VOISS (Voice Over IP Softswitch) solution.” Go-Comm “VocalData Inc., the technology leader in the service delivery softswitch market, today announced that its award-winning Voice Over IP Softswitch (VOISS) solution has been deployed by Go- Comm, Inc. to provide voice over IP services in the Dallas area.” Sources: See Appendix M.

Table 4. Major Softswitch Manufacturers Manufacturer Softswitch Description Product Tachion Fusion 5000 “will be used by our service provider customers as an alternative to traditional legacy central office composed of a class 5 voice switch surrounded by a number of data devices”; “collapses all the functions of the telephone company’s central office into a box the size of a dorm room refrigerator”; It starts at around $270,000 compared to up to $2 million for a traditional Class 5 circuit switch. Axtar Limited OneSwitch “supports both circuit switched interfaces such as TDM (E1 or T1) as well as IP (Ethernet) network interfaces,” and is “a complete replacement for a CLASS 5 or CLASS 4 central office switch and can be implemented on its own as the primary (core) switch in a small network or as an edge switch for larger networks.” Santera Systems SanteraOne “an all-in-one C.O. solution that integrates the entire next-generation switching solution within a single chassis. This all-inclusive solution offers CLASS 4 and CLASS 5 functionality, ATM, IP, TDM, and frame relay switching, signaling, media gateways and controllers, and IP routing.”; “costs about as much as what you’d spend on the switch room for a Class 5 switch”; “can be a replacement for either a legacy Class 4 or Class 5 circuit switch” Uniphere Networks BroadSoft In March 2001, “completed Class 5 customer trials of its BroadSoft platform.” Cisco BTS 10200 “has been in a GA [generally available] state for about eight months.” It is “being upgraded to its second release of software. It supports a substantial number of business voice calling features, making it one of the front runner contenders for Class 5 replacement opportunities. It also implements all mandatory Class 5 and core network switch features, such as 911, LNP, DAOS, SS7, AIN application access, etc.” Sonus GSX9000 “a carrier-class switch that is currently capable of supporting roughly 100,000 simultaneous calls while maintaining 99.999% reliability. One of the benefits of the GSX9000 is the small footprint needed for deployment; Sonus’ GSX9000 reduces the required C.O. space by roughly 90% compared to traditional circuit-based switches. This greatly reduces the cost of deployment, which management estimates to be roughly 50% of per-port costs and 45% of operating costs.”; “Our switch is ready for prime time because it’s already widely in deployment, mostly in Class 4.” Convergent Integrated Convergent Networks is “expected to have a softswitch with Class 5 Networks Convergence functionality available this quarter. Switch (ICS) Tacqua Open Compact “Class 5 alternative switching system with integrated Softswitch functionality Exchange (OCX) providing a clear migration path to next-generation packet-based networks.” Nortel Communication “New venture capital startups with little or no telephony experience can use Server 3000 this solution as an entry-level vehicle to the Voice-over-IP market – supporting next generation line-side services.” Syndeo Corporation The Syion 426 “The Syion 426 is a powerful second-generation, carrier-grade CLASS 5/Local Exchange softswitch”; “The Syion architecture was purpose-built for the delivery of regulatory (primary local exchange) services such as emergency/lifeline services, operator services, directory assistance, and lawful intercept.” In February 2002, The Armstrong Group, which operates telephone and cable networks in the eastern U.S., announced that it would deploy the Syndeo Syion 426 softswitch platform in Western Pennsylvania. Convedia Convedia CMS- “The Convedia CMS-6000 Media Server has been designed and developed Corporation 6000 Media specifically to meet the challenges of delivering enhanced voice and video Server services over packet networks. . . . Convedia’s modular hardware and software architecture lets you enter the enhanced services market quickly and affordably.”

APPENDIX K. CLEC NETWORKS BY MSA

This appendix tabulates the number of CLEC networks in the 150 largest Metropolitan Statistical Areas (MSAs). It is based on the CLEC reports prepared by New Paradigm Resources Group (NPRG).

The data for 2001 are from NPRG’s latest report – the CLEC Report 2002 – which describes CLEC networks as either “Operational,” “On-Net,” “Resale,” or “Planned.” We have tabulated only Operational and On-Net networks, both of which appear to involve the use of a CLEC’s own facilities. CLECs operating On-Net networks are indicated in italics.

The data for 1998 are based on NPRG’s CLEC Report 1999, which describe CLEC networks as either “Operational,” “Off-Net,” or “Planned.” We have counted both “Operational” and “Off-Net” networks in the 1998 totals. CLECs operating “Off-Net” networks are indicated in italics.

In some MSAs, the total number of Operational and On-Net networks exceeds the number of CLECs operating within those MSAs. This is due to the fact that, in some instances, individual CLECs operate multiple networks within the same MSA.

The 2001 totals include the networks of CLECs that have declared bankruptcy. Most such CLECs are still operational (and some are now emerging from bankruptcy). Moreover, network facilities such as fiber are a sunk investment, so if one company ceases to use its network it is highly likely that another company will quickly seize the opportunity to do so (and will probably be able to obtain the facilities at a fire-sale price). In any event, networks operated by CLECs that have declared bankruptcy (as of March 31, 2002) represent no more than 18 percent of the totals counted here.

APPENDIX L. ESTIMATING CLEC SPECIAL ACCESS MARKET SHARE

According to the FCC’s most recent Telecommunications Industry Revenues report, the Bell companies earned $13.3 billion in the provision of “local private line and special access” and “long distance private line services” in 2000.1 Special access revenues are the sum of these two revenue categories.2

The problem with using the FCC’s revenue data to estimate CLEC special access revenues is that several CLECs – including the two largest, AT&T and WorldCom – report their special revenues as both CLECs and “toll carriers.”3 For example, when AT&T and WorldCom use their local facilities to supply special access to their long distance network, they typically report that revenue as toll carriers.4 Not all of the local and long distance private line revenue that these carriers report as toll carriers is necessarily special access revenue, however, and there is no precise way to back out the portion that is.

Rather than engage in guesswork, we have relied on an alternative source for CLEC special access revenue. According to New Paradigm Resource Group’s CLEC Report 2002 (15th ed. 2002), CLECs earned $8.4 billion from the provision of special access/private line services in 2000.5 Using the New Paradigm figure for CLEC special access revenues and the FCC figure for BOC special access revenues yields a CLEC market share of approximately 39 percent in 2000.

Even using FCC data, however, yields a very high market share. According to the most recent Telecommunications Industry Revenues report, CLECs earned $4.1 billion in the provision of local private line and special access and long distance private line services in 2000.6 In addition, toll carriers reported $100 million in local private line revenues.7 AT&T also has

1 FCC Telecommunications Industry Revenues, 2002 ed. at 13 (Table 5, Lines 305 & 312), 17 (Table 6, Lines 406 & 415). 2 The FCC defines “long distance private line services” to “include revenues from dedicated circuits, private switching arrangements, and/or predefined transmission paths, extending beyond the basic service area. This category should include revenues from the resale of special access services.” FCC, Telecommunications Reporting Worksheet, FCC Form 499-A, Instructions for Completing the Worksheet for Filing Contributions to Telecommunications Relay Service, Universal Service, Number Administration, and Local Number Portability Support Mechanisms, at 18 (Feb. 2001) (emphasis added). AT&T has acknowledged that special access revenues represent the sum of these two categories. See Declaration of C. Michael Pfau on Behalf of AT&T Corp. ¶¶ 13-14, attached to Reply Comments of AT&T Corp., Implementation of Local Competition Provisions of the Telecommunications Act of 1996, CC Docket No. 96-98 (FCC filed Apr. 30, 2001) (“Pfau Decl.”). 3 See id. ¶ 16 (“Arguably, MCI/WorldCom and AT&T fall within the category of ‘Toll Carrier’ and, as a result, any self-supplied special access may not be included in the CLEC figure.”). 4 See id. ¶ 17 (“self-supplied access would not be encompassed in the figures and, hence, the need for an adjustment”). 5 NPRG CLEC Report 2002, 15th ed., Ch. 3 at Table 10. 6 FCC Telecommunications Industry Revenues, 2002 ed. at 14 (Table 5, Lines 305 & 312), 18 (Table 6, Lines 406 & 415). 7 FCC Telecommunications Industry Revenues, 2002 ed. at 16 (Table 5, Line 305), 19 (Table 6, Line 406).

acknowledged that the access that AT&T and WorldCom supply to themselves was worth approximately $900 million as of 1999.8 Assuming that the value of these two carriers’ self- supplied special access increased in 2000 by the same amount as it did between 1998 and 1999, the value of this self-supply was approximately $1.1 billion in 2001.9 That brings total CLEC special access revenues to $5.3 billion under FCC data. This represents a market share of 28 percent.

This figure is undoubtedly too low, however. First, it fails to account for self-supply by long distance carriers other than AT&T and WorldCom, even though many such carriers have local access facilities of their own, and can reasonably be expected to use these facilities to self- provide access to some extent. Second, it excludes completely any special access revenue that AT&T and other interexchange carriers report as long distance private line revenue and that is earned by reselling the services of other CLECs and ILECs. This amount is substantial, as the interexchange carriers are the largest special access customers of both many CLECs and the ILECs, and purchase such services in order to resell them to end users.10

Finally, CLECs’ share of the special access market was likely even higher in 2001 than it was in 2000. For example, according to the FCC’s most recent Local Telephone Competition report, CLECs’ share of large business lines increased from 17.5 percent to 19.1 percent from December 2000 to June 2001.11 New Paradigm reports that CLEC special access revenue grew by more than 20 percent between 2000 and 2001.12

8 Pfau Decl. ¶ 16. 9 Pfau Decl. ¶ 16 (value of AT&T and WorldCom self-supply increased from $627 million in 1998 to $856 million in 1999). 10 AT&T has acknowledged that adding this total to CLEC local access and private line revenue would bring total special access revenues in line with the totals reported by New Paradigm. See Pfau Decl. ¶ 19 n.4. AT&T has nonetheless argued that it is appropriate to exclude such revenues, but neither of its explanations provides an adequate justification for its approach. First, AT&T has claimed that CLEC/IXC long distance private line revenues should not be counted because the ILECs do not typically compete in the provision of long distance private line service. But the extent to which ILECs provide long distance private service obviously is irrelevant; the only relevant question is the extent to which competing carriers provide private line and special access services that compete with the private line and special access service that ILECs provide. Second, AT&T has claimed that including in the market share calculation the toll carrier special access revenues reported as long distance private line would lead to double counting because ILEC wholesale revenues are included as a cost for Toll Carrier services and reflected in their end user revenues. But including the revenue that competing carriers earn from leasing a CLECs’ or ILECs’ facilities or reselling their service is not necessarily double counting, because the competing carrier invariably marks up its own retail service to end users over and above the wholesale price. In addition, CLECs often will supplement the services they resell with one or more value-added services to distinguish themselves. In any event, even assuming that there would be some double counting, this is hardly an argument for excluding this entirely as CLEC revenue. Such revenue clearly is CLEC revenue, even if it is earned from customers that are not served entirely over the CLEC’s own facilities. 11 FCC Local Competition Report, Feb. 2002 ed. at Table 2. 12 NPRG CLEC Report 2002, 15th ed., Ch. 3 at Table 11.

Figure 2. Distribution of CLEC Packet Switches 1998. NPRG CLEC Report 2000, 12th ed., Ch. 6, Table 9 (restated 1998 data). 2001. NPRG CLEC Report 2002, 15th ed., Ch. 4 at Table 18. This is a highly conservative estimate. It does not include the 840 packet switches NPRG lists for competitive Independent Operating Companies, utility CLECs, data providers, or Gig-E providers. In addition, it does not include the 7,000 packet switches that NPRG lists for AT&T as of year-end 2001. According to NPRG’s prior reports, AT&T had only 50 packet switches as of year-end 2000. Because one-year growth of this magnitude is unlikely, in an abundance of caution we have used the 2000 figure for AT&T’s packet switches.

Figure 3. Distribution of CLEC Fiber 1998. NPRG CLEC Report 2000, 12th ed., Ch. 6 at Table 5 (restated 1998 data). 2001. NPRG CLEC Report 2002, 15th ed., Ch. 4 at Table 13. This is a highly conservative estimate. It does not include 117,000 route-miles of fiber that NPRG lists for competitive Independent Operating Companies, utility CLECs, data providers, or Gig-E providers. Moreover, the total miles for 2001 have been adjusted downward to address the concerns that CLECs raised in the Special Access proceeding in April of 2001 (CC Docket No. 96-98).

Introduction

1. The Commission’s Triennial Review proceeding affords the opportunity for the agency to assess the current state of local exchange competition and to review its network unbundling regulations. The purpose of this paper is to respond to the Commission’s Notice by examining the empirical evidence to date on entry and UNE consumption and discussing the economic implications of that data both for current market performance and for unbundling policy going forward. The principal conclusions of this paper are the following:

· Unbundling in the absence of a clear showing of impairment would be socially costly. Facilities-based competition promises far greater benefits than does competition through unbundled access and should never be displaced by unbundling rules.

· Unbundling can undermine facilities-based competition and therefore cannot be considered a costless policy that will merely provide an alternative or complement to competing facilities. A rigorous showing of general (as opposed to firm specific) impairment to competition should be required before unbundling is retained for a network element. Such a showing should be considered defeated by actual evidence that competitors are obtaining necessary facilities without recourse to UNEs.

2 · Even when unbundling has proven necessary to initiate competition, the Commission should not find that market entry continues to be impaired once competing facilities actually do, or feasibly could, become available.

· Once facilities-based competition arises or proves economically feasible, unbundling should not be mandated at any price. The question of whether to require a network element to be unbundled should be treated independently of, and prior to, the question of the pricing of such unbundled access. Of course, once a determination is made as to which elements should be unbundled, it then becomes critically important to establish prices that preserve economically rational incentives to invest in competing facilities.

· Empirical evidence demonstrates that the local exchange market has become significantly more competitive since passage of the 1996 Act and, more importantly for the instant proceeding, that some network elements that have been required to be unbundled are now being competitively supplied in substantial amounts.

· Current data provide a compelling case that new entrants would face no competitive impairment if ILECs did not unbundle local switching. Similarly, interoffice transport is now being competitively supplied by competitive local exchange carriers as well as by third-party suppliers of transport facilities. Finally, the loop market is also becoming increasingly competitive, especially in the provision of high-capacity loops. New entrants are in fact entering the market for each of these elements unimpaired and the case for their mandatory unbundling has evaporated.

· In light of the empirical evidence, the FCC should reduce the current list of unbundled elements and should adopt a strong presumption against finding impairment where actual market data shows entry through paths other than unbundling.

2. This declaration is organized as follows. Part I provides theoretical background on unbundling and on the comparative economics of alternative entry paths into the local exchange business to provide a framework for drawing policy inferences from the empirical evidence. Part II discusses the policy precedent for eliminating unbundling where there is evidence of competing facilities. Part III examines empirical data on competition in the local exchange presented in the UNE Fact Report 2002, filed in this proceeding by BellSouth, SBC, Qwest and Verizon (“Fact Report”), and discusses the changing case for the unbundling of several individual network elements. Part IV concludes.

3 I. The Economic Importance of Correct Unbundling Policy

3. The overarching question for the Commission in this proceeding is whether competitors are currently impaired in entering the local exchange market if they lack access to a given unbundled network element (UNE) from an ILEC. To have any economic content, “impairment” must at a minimum mean that there is no option that would enable a carrier to compete in the local exchange market other than obtaining the element at issue from the ILEC under regulated unbundling. If other, non-UNE, options are available to CLECs—e.g. purchasing their own facilities or obtaining access to those owned by third parties—then the case for impairment cannot be made and unbundling should be repealed for that element.

4. In assessing the case for impairment, it is important for the Commission to adopt a realistic baseline from which to judge the development of local competition. If the standard for successful progress in local telephony is geographically ubiquitous entry, then the Commission risks finding impairment in markets that CLECs never intended to enter in the first place. The relevant question is not whether CLECs are entering local markets everywhere, but whether CLECs can enter without impairment the markets that they have demonstrated a realistic intent to enter. When the question is phrased this way, the Commission can more correctly assess alleged ILEC advantages due to incumbency. An incumbent’s unrivaled presence in markets that present an unattractive business case does not necessarily mean the incumbent has advantages over rivals in other markets.

5. Unbundling of network elements is not a costless path to competition. If unbundling substitutes for facilities-based competition, consumers lose on multiple fronts. First, they will receive fewer price and output related benefits than they would receive from head-to-head competition among independent networks. Second, they will receive fewer long-term benefits from development and deployment of innovative technologies and services. In addition, they will not have the robustness and security that comes from having multiple sources of local exchange service. Unbundling

4 should not, therefore, be viewed as a harmless policy for fostering competition or as a mere back-up to more conventional means of competitive entry. The back-up can become the primary path and in so doing cause important social benefits to be lost. Unbundling thus needs to be understood for what it is: a risky policy that, if not carefully and selectively implemented, could deter innovation and displace superior improvements to market performance through conventional, facilities-based, entry.

6. Accordingly, as the Commission moves forward with its unbundling regulations the appropriate policy guideline where the case is close is to err against finding impairment. For reasons to be discussed in this section, the expected costs of any errors against unbundling will be much lower than the costs of errors that extend or maintain unbundling. The Commission therefore should not require that any element be unbundled if empirical evidence shows the market for that element to be susceptible to facilities-based entry and competition. In such cases, the presumption against impairment should be strong and be rebuttable only by a convincing and particularized demonstration to support a finding by the FCC that, without unbundling, efficient entry into a given market would not be feasible. To set the presumption otherwise would be to harm non-UNE-based competition, to lose substantial consumer benefits over time, and to undermine the objectives of the 1996 Act.

A. Comparison of Unbundled Access and Facilities-Based Entry 7. Consider the comparative dynamics of competition through unbundling and competition based on rival facilities. When two firms use the same network to provide service, they for the most part have the same minimum production costs. To be sure, they may have some costs that are independent, such as those of marketing or customer service. But the sharing of facilities necessarily reduces the scope of the carriers’ abilities and competitive incentives to reduce production costs. In comparison, when rival facilities compete in the marketplace, they have distinct production costs and each competitor has strong incentives to reduce the costs of producing its service in order to cut prices to consumers and gain market share. All

5 else being equal, facilities-based competition promises much greater price and output benefits for consumers than competition over shared network facilities does. As Justice Breyer plainly put the point somewhat in his separate opinion in Iowa Utilities Board. v. AT&T, 525 U.S. 366, 430 (1999): “A totally unbundled world—a world in which competitors share every part of an incumbent's existing system, including, say, billing, advertising, sales staff, and work force (and in which regulators set all unbundling charges)—is a world in which competitors would have little, if anything, to compete about.”

8. Similarly, when firms use common facilities, the industry at issue is less likely to create or deploy innovative technology or services. The fewer the competing networks, the smaller the possible set of alternative approaches to innovation. With fewer firms pursuing independent innovation efforts, the less likely it is that new services will be introduced in a given time frame. More fundamentally, the incentive to engage in innovation in the first place declines when rival service operators use a shared network. For, the innovator will share any benefits it creates with others using the network rather than capturing the returns itself. The incumbent’s investment in its network will in effect create a positive externality for UNE users, and the operator’s incentive to undertake such investments will diminish to the extent it cannot capture returns from that externality. Much of the incentive to innovate can come from desire to gain an edge over rivals, which is not possible if those rivals automatically get access to the innovation in question.

9. On the other hand, when a carrier faces competition from rival networks, it will have an incentive to cut its own costs and to offer new services to its customers as a means of gaining market share from its rivals. Indeed, empirical evidence suggests that, over the history of U.S. telecommunications, deployment of new technology and services has occurred more quickly in markets that contain competing networks than in markets with only one network.1 An analysis by FCC staff, for example, attributed

1 See, e.g., Howard Shelanski, “Competition and Deployment of New Technology in U.S. Telecommunications,” U. Chi. Leg. Forum 85 (2001).

6 accelerated deployment of DSL service to pressure from cable networks’ broadband offerings. 2 Fiber deployment in the long-distance telephone sector, the virtues of which were appreciated by the late 1970’s, accelerated only with the full-scale, facilities-based entry of Sprint upon the implementation of equal IXC/LEC interconnection after the AT&T divestiture in 1984. 3

10. Innovation concerns not only counsel against retaining unbundling requirements where market evidence shows competitive facilities, but also against extending unbundling obligations to new kinds of equipment or services. When new, advanced technology becomes available and new kinds of services are introduced into the marketplace, the costs, risks, and uncertainty may all be quite substantial. To require ILECs to unbundle such facilities to competitors will impede deployment of new technology and services, to the detriment of consumers. Just as the balance of risks weighs against continuing to unbundle facilities that are becoming competitively supplied, it weighs against unbundling advanced facilities that are not yet supplied at all on a wide scale or that are just beginning to be supplied. The ILEC itself is newly entering the provision of such services and facilities.

11. Even if the ILEC were the sole emerging provider of such advanced capabilities (which is not the case), the Commission should not extend unbundling to the relevant new facilities if implementation of advanced technology is to be encouraged. Simply put, just as impairment should not be found for existing UNEs that become competitively available in the marketplace, impairment should not be found for advanced services facilities that are just entering the market and which the ILECs themselves are just beginning to deploy. Examples of such new technology include fiber-based local loop technologies and packet switching.

7 12. Whereas both the current and long-run costs of displacing facilities-based competition with unbundled access may be quite high, the countervailing benefits of unbundling are limited. Unbundling can in theory lead to more efficient use of existing facilities and thereby dissipate any monopoly effects in the incumbent’s provision of network- based services. It can also create competitive pressure to innovate in non-facilities aspects of service provision, such as marketing, customer service, or packaging of services. It is essential to recognize, however, that none of the above benefits is unique to unbundling. Each would flow, and to a much greater degree, from facilities- based entry. Pricing, service quality, and innovation would all improve more directly and dramatically from efficient introduction of competing facilities than from allowing new entrants to use existing networks.

13. The most important benefit generally ascribed to unbundling is that it can serve as a transitional mechanism to facilities-based competition where otherwise such competition would not arise or would arise only piecemeal. As a threshold matter, that is not how UNEs are in fact used and the mere fact that new entrants cannot feasibly construct ubiquitous networks does not make the case for unbundled access. Even if new entrants cannot offer full networks from the outset, they may be able to build out incrementally and to obtain interconnection with other carriers such that viable entry does not depend on unbundling. Currently, more than half of CLEC lines are served entirely over the CLECs’ own facilities (Fact Report, Section I, Figure 3). To the extent the choice is genuinely one between monopoly and competition through unbundling, requiring unbundled access may be sound policy. 4 But the unbundling- as-transition argument cannot by its terms provide an enduring justification for such regulation. There is a serious risk with infant-industry or infant-firm policies that the infants never grow up. Once the transition to non-UNE-based competition actually occurs, or once it can be shown that competition can occur without resort to UNEs, there is no need to maintain unbundling requirements.

4 It is not necessarily the case that unbundling will be preferred to monopoly, however. There are administrative costs to unbundling as well as productive inefficiencies—for example from possible reduction of investment incentives for the network owner—that could offset the benefits of competition

8

14. Equally importantly, even if the transition to facilities-based competition does not occur and UNE consumption continues, then regulators must consider the possibility that unbundling has been implemented in a manner that causes firms to substitute entry using incumbent networks for entry over their own facilities. The paradox is that the same evidence some might use to prove impairment but for unbundling— high levels of unbundled access consumption—might in fact prove something very different and lead to exactly the opposite policy prescription. Indeed, it could demonstrate that unbundling provides an alternative to facilities-based entry that benefits some new entrants (those that choose not to invest in facilities) but not competition or consumers.

15. Substitution of UNEs for facilities-based entry is not merely conjectural. By 1999, when the FCC last reviewed its UNE regulations, competitive provision of DSL was well under way. Many data CLECs supplied their own electronic facilities (i.e. DSLAMs), which they collocated in ILEC central offices. Yet many other CLECs nonetheless contended that competition would be impaired without an unbundled “packet UNE.” The Commission mostly rejected that unbundling request, but the key point is that even where impairment clearly did not exist, a group of entrants preferred to opt for unbundling over purchase of their own facilities.

16. It is thus necessary, if sound policy is to be implemented, for regulators to examine market developments carefully and to credit fully the importance of data on the entry of independent, competitive facilities. Costly tradeoffs are likely to result if regulations require unbundling of a network element once market evidence demonstrates that new competitors can—whether they actually choose to or not— economically provide that facility for itself, obtain it from third parties, or obtain if from the ILEC under arrangements other than regulated unbundling. Such a policy runs the risk of supplanting the substantial benefits of facilities-based entry with the

through unbundled access. But it cannot be questioned that the case for unbundling is strongest where it can be demonstrated that there is no other likelihood of competitive entry.

9 comparatively anemic returns, and potentially high costs, of unbundled access. Given this tradeoff, the Commission should presume impairment does not exist where the market demonstrates the entry of alternative facilities and should in such cases place the burden on CLECs rigorously to demonstrate that impairment persists if unbundling of a given element is to be continued.

B. Once Entry Without Reliance on UNEs Proves Viable, The Case for Impairment, and hence for Unbundling, Evaporates

17. Once entrants have demonstrated that they can enter the local exchange market without resort to particular unbundled elements, the Commission should no longer mandate that those elements be unbundled. The feasibility of facilities-based entry and other alternatives to UNE-based competition accomplish all of the goals that the 1996 Act sought to reach through unbundling. Such options first and foremost demonstrate that entrants will not be impaired without unbundled access to ILEC facilities. Second, they either provide a transitional mechanism to full facilities-based entry or show that such a transitional alternative is not necessary. And third, they show that the market has become a less uncertain place for CLECs to do business in terms of the availability of competitive facilities or of the financial feasibility of constructing one’s own facilities.

18. The case of interoffice transport is a good example of the above changes. CLECs and third parties both found a business case for building transport facilities to use themselves or lease to others. Any CLEC entering the market can thus see that construction of its own transport is feasible, yet can still purchase such transport from a third party if it opts not to build over the short or even long run. The same facts apply to switching. As new entrants add their own switch capacity, they not only free themselves from relying on ILEC facilities, but they also create a non-ILEC source of leased switching capacity for new entrants who choose, for whatever reason, not to invest in their own equipment.

10 19. The same arguments that counsel against unbundling where competitive facilities can exist also apply to extending unbundling to cases where regulated or tariffed arrangements between ILECs and other carriers eliminate impairment. Interexchange carriers and CMRS providers, for example, have had no difficulty obtaining special access from the ILECs through non-UNE agreements. Indeed, IXCs and others have been successfully providing competitive access for a decade. There is thus no case for extending unbundling obligations to special access or indeed any case in which other arrangements have proven sufficient to defeat competitive impairment.

20. One might argue that unbundling will simply coexist with, and not supplant, facilities-based competition where the latter is feasible. From that standpoint unbundling is simply another alternative entry path that should be left open to entrants. This argument is flawed for several reasons. To begin with, even if unbundling were to substitute only marginally for facilities-based entry, the foregone consumer gains could be substantial. But when unbundling is available, its substitution effect is likely to be more than merely marginal.

21. First, unbundled access may offer a new entrant certain advantages over facilities- based entry, even if the latter would better serve competition and consumers. For example, an entrant may perceive entry over the incumbent’s facilities as less risky or more profitable than entry on a facilities basis, even where, absent the unbundling option, the entrant would have found it economical to build its own facilities. An entrant might also prefer to limit the competitive pressure that would result from facilities-based competition by opting instead for unbundled access. That option would free the entrant from having to engage in independent innovation efforts and, moreover, afford it an option on any advance in the network implemented by the incumbent. While an economically correct UNE price would include the value of that option, the pricing solution (which would itself be very difficult accurately to achieve) does nothing to compensate for the reduction in independent innovation activities. Consumers bear the resulting costs in the form of reduced flow of cost- reducing advances in the network and reduced flow of new service options.

11

22. An entrant might also use unbundled access as a way to defer investment in its own facilities until such time as a new generation of technology emerges. This latter strategy is not inefficient in cases where no firm would rationally invest in today’s technology because of forecasts about tomorrow’s better technology. No firm wants to strand costs and there may be times when it is rational to wait to enter the market when significant technological change is in prospect. A problem arises, however, where it would be efficient for a firm to invest in today’s technology and enter the market with its own equipment, but where it instead opts for unbundling while it waits for future technological developments. Each such use of unbundling to play socially inefficient “wait and see” games further defers true competition.

23. Second, unbundling requirements entail regulated rates for unbundled access, which in turn add to the costs and economic risks of unbundling. The administrative difficulties of setting economically correct prices for network elements are not trivial. If rates turn out not to match costs exactly and instead to understate actual costs, then those rates will fail accurately to communicate to entrants the relative prices of alternative entry options. The costs of such inaccuracies are very high. In particular, if UNE prices understate the total costs of unbundled entry, they will systematically bias entrants towards unbundling and away from facilities-based competition.

24. At the same time, prices that are too low will deter the incumbents from making investments in their own networks because they will have to share the benefits, although not the full costs, with competitors using UNEs. Moreover, to retain mandatory unbundling once there is no longer impairment is to raise the possibility that UNE prices will undermine those CLECs that have invested in their own facilities. State or federal regulators must not only get pricing right initially, but they must ensure pricing remains appropriate each time they revisit and revise pricing over time. Even if UNE prices send accurate signals for a time, they might later fall to the point that facilities-based CLECs are at a comparative disadvantage to CLECs using UNEs, even though the former may have more efficient networks. This problem of

12 shifting price signals is not conjectural. Several states have already held multiple pricing proceedings and in some cases, for example New York, have radically revised UNE rates over just a couple of years.

25. I do not here intend to delve into the complex and contentious issue of UNE pricing. The point is simply that an unrealistically strong assumption of sustained accuracy in setting regulated UNE prices is required before one can say with any confidence that an unbundling option will not affect incentives to build new, competing facilities or to improve existing ones. The results of different state pricing proceedings make clear just how unlikely it is that regulators will set prices correctly. In Indiana, for example, the UNE price for a loop is between $8.00 and $8.99 per month, with an average price of about $8.30. This is about half the national average. It is also far less than the rates in all states with similar population densities. The population per square mile in Indiana is 168. In North Carolina, with a population density of 155 per square mile, the average loop price is $15.88. In Georgia, with a population density of 142, the average loop price is $16.51, while in Tennessee, where the population density is 136 people per square mile, the loop rate in Tennessee is $14.92. It seems improbable that these price differences reflect purely cost differences. The correct explanation is more likely that setting UNE rates is an exercise fraught with opportunity for imprecision and error.

26. Of course, once a determination is made that some elements should be unbundled, it is important that the prices for unbundled network elements be set correctly where unbundling does occur. Otherwise, those prices will further exacerbate the deterrent effect that unbundling has on investment in competing facilities. I have explained elsewhere that the Commission’s current TELRIC pricing rules do not preserve economically rational investment incentives and need to be revisited. But for the present purpose the key point is that these efficient price adjustments should not substitute for careful analysis of whether competitors are truly impaired without access to a given network element. The potential economic costs of unwarranted unbundling cannot be cured through mere adjustments in the price of unbundled

13 access. Once facilities-based competition in a UNE market arises or proves economically feasible, unbundling should not be mandated at any price. The question of whether to require a network element to be unbundled should be treated independently of, and prior to, the question of the pricing of such unbundled access.

27. The arguments against trying to adjust unbundling rules at the level of pricing instead of at the level of the elements themselves include the same reasons, listed above, for why firms might privately choose unbundling even where the social benefits of facilities-based entry are higher. But there are other reasons as well. First, ongoing price regulation entails ongoing administrative costs. Once CLECs are no longer impaired in their ability to build or obtain network elements in the marketplace, there is no reason to incur the administrative cost of overseeing regulated access to that element.

28. Second, the mere opportunity to obtain unbundled access at cost-based rates may induce new entrants to resort to UNE price negotiations or arbitration in the hope of obtaining comparatively advantageous entry terms, even where they face no impairment in entering on a non-UNE basis. Again, there is no need to speculate about such strategies: several states have held proceedings to adjust UNE rates over the same time period that the Fact Report shows facilities-based entry to be proving viable in markets covered by the UNE rates at issue.

C. Neither Alleged Transaction Costs of Combining UNEs Nor Demand for a UNE “Platform” Should Affect the Commission’s Element-by-Element Impairment Analysis

29. Once the Commission determines that competitors are not impaired by lack of regulated access to an ILEC network element, the inquiry should end. The FCC’s determination should not be undermined by claims that the element should nonetheless be unbundled because it is part of a desired UNE platform or because of

14 alleged transactions costs in combining a mix of the CLEC’s own facilities, UNEs, and/or third party facilities.

30. The threshold, necessary condition for unbundling in the 1996 Act is impairment, which must be demonstrated on an element-by-element basis.5 If evidence demonstrates that CLECs have viable alternatives to an ILEC’s network elements, then there is no economic impairment as to those elements. It might be that in some cases there are costs to combining elements that a CLEC obtains on its own with those that it obtains on an unbundled basis. But those “combination costs” should not be a mechanism by which network facilities, which on their own cause no competitive impairment, are bootstrapped back onto the list of required unbundled elements. In such cases competitors should bear the burden of showing that the transaction costs of combining elements are so high that they make alternatives economically infeasible for each UNE and thus create impairment compared to the ILECs, which themselves must incur the costs of combining their own network elements. In other words, the CLECs must show that despite availability of non-ILEC facilities for lease or purchase, they will be truly, comparatively impaired by resorting to those alternatives.

31. The mere existence of some combination costs, or the mere fact that entrants would find unbundling to be cheaper than building their own facilities or other alternatives, does not carry this burden because carriers could still compete without reliance on the UNE. Indeed, the CLECs must be able to show that the up-front or continuing transaction costs of non-UNE alternatives are so high as to render them uneconomic for competitive entry. Given the facts of actual competitive entry for the services CLECs seek to offer, without reliance on UNEs, this is an argument that may exist in theory, but fails in fact.

5 In section 251(d)(2), the Act sets up impairment as a “minimum” limiting factor on unbundling. Impairment is a necessary but not always sufficient condition for unbundling under the Act. The Commission may therefore limit the list of unbundled elements even if carriers can demonstrate impairment.

15 32. Similarly, arguments that a UNE “platform” is necessary for entry should not be able to drive individualized, element-by-element analysis of competitive impairment. There is no “platform” UNE, only a platform of those individual elements the Commission has ordered to be unbundled. The “platform” proceeds from the list of individual UNEs. To allow the determination to work in reverse would pervert the statute and undermine more complete development of local exchange competition.

33. There are a number of ways that the platform might be claimed to require continued unbundling of a UNE that can be competitively provided or obtained. For example, some competitors might argue that removal of a UNE from the platform would disrupt their current infrastructure configuration and impose transaction costs, so that the element should be kept on the UNE list. Yet this turns impairment analysis on its head and creates a one-way ratchet in the direction of sustained unbundling. Second, such CLECs might propose that even if an element need not be unbundled in itself, it should be retained as a required element for CLECs buying the whole platform. This creates a new UNE, the platform itself, and creates a bias towards increased UNE consumption by effectively granting a longer list of available UNEs to CLECs that adopt an entirely UNE-based strategy than those who actually build their own facilities or obtain them from competitive sources to the ILEC. The result is a disincentive for non-UNE-based competition that directly contradicts the intention that UNEs serve as a transitional mechanism towards facilities-based entry.

34. Finally, it might be argued that even if an element no longer causes impairment and hence need not be unbundled, it should nonetheless be made available on some basis as part of the platform. This option drags regulators into a complex pricing exercise and amounts to maintaining a “platform UNE,” albeit at perhaps a higher price than would otherwise prevail. Such a hybrid of UNEs and services is not an option under the statute and would be an administrative quagmire.

D. Unbundling Imposes Substantial Costs on Regulated Carriers

16 35. In addition to the substantial social costs that result when competitors substitute UNEs for facilities-based entry, other economic harm flows from the costs that unbundling imposes on the ILECs directly. To provision a UNE, an ILEC must not only incur a new set of administrative costs unrelated to serving its end-users, but it must also make investment and design decisions with estimates of CLEC demand factored in. But because CLECs need not continue to purchase a UNE over time, an ILEC may be stuck with investment, made to accommodate projected CLEC demands, which the ILEC cannot recover. ILECs must therefore factor in much higher risk in all of their forward-looking network investments. This in turn raises the cost of such investment and impedes network development over time.

36. The costs to ILECs and ultimately to consumers are likely to be especially high where new technology is at issue. Deployment of new infrastructure proceeds well in advance of demand. Substantial risk and uncertainty accompany any such investment. If ILECs must also contemplate having to unbundle such infrastructure to competitors at cost, the return on such investment becomes less certain and hence less attractive. This is particularly so where the amount of ILEC investment necessary to implement new technology is increased by the possibility of mandated access for CLECs to that technology. Consider the case of SBC’s provision of collocation for CLEC electronics on the line-side of new, digital loop carrier plant. To comply with this requirement, SBC has reported that it has spent $20 million thus far and will be forced to spend an additional $30 million if it continues to deploy remote terminals in accordance with its original Project Pronto plans. SBC also states that it was required to reconfigure its network design so that the transmission component of its broadband service could be made available to competitors. This requirement forced SBC to deploy in its central offices optical concentration devices that would not otherwise have been necessary and that have added nearly $200 million to Project Pronto network costs. In addition, SBC reports that state requirements that it provide splitters for line sharing have added another $107 million in costs. SBC says that it has been able to recover virtually none of these additional costs because, as it turned out, not a single CLEC has collocated in an SBC remote terminal or elected to use its

17 broadband service (other than its own affiliate), and only 14% of the line splitters it deployed are being used.6 SBC’s reported experience illustrates why the costs of accommodating competitive access need not always be productive and can in fact cause substantial waste of resources. Regulatory mandates that such expenditures be made to enable unbundled access, well in advance of any demonstrable need and demand for the end-user service at issue, will raise costs without likelihood of compensating benefits.

II. A Cautious And Rigorous Approach to Unbundling is Consistent with Established Principles of Competition Policy

37. Evidence of competition in the provision of a network element should weigh heavily against continued unbundling of that element. Such a policy presumption is consistent with general principles of competition policy and with important precedents from antitrust.

38. As a threshold matter, one might object that the Telecommunications Act of 1996 is not meant to replicate the antitrust laws and is expressly intended to impose a different and more generous standard for unbundling than that which might be implied under the Sherman Act. That may well be true and I take no position here on the comparison between the 1996 Act’s “impair” standard and the “essential facilities” doctrine of antitrust law. Rather, the important point is that antitrust law contains valuable lessons for network unbundling that do not hinge on possible differences in statutory standards. First, antitrust law requires or permits use of common facilities only when competition overall will not be harmed by such outcomes. To be sure, applicable antitrust precedents require that much more be shown before a firm can get access to a competitor’s facilities. But even if the FCC’s

6 Comments of SBC Communications, Inc., In the Matter of Deployment of Broadband Networks and Advanced Telecommunications Services, Docket No. 011109273-1273-01, at 26 (December 19, 2001); Ex Parte Letter from James Smith, SBC, to William Caton, Acting Secretary, FCC, CC Dkt 96-98, March 25, 2002.

18 unbundling standard is more lenient than that of antitrust law, the precedent of ensuring that, at a minimum, overall competition is not harmed through unbundled access, is worth importing into this proceeding. To allow for unbundling where facilities-based entry is possible and economically more beneficial would be contrary to this principle.

39. Second, antitrust law draws an important distinction between competition and competitors. The disadvantage suffered by an individual competitor is not cognizable harm under the antitrust law unless that disadvantage flows from conduct that more generally harms competition itself. A similar principle is beneficial in the UNE context. It may be the case that one or another putative entrants into the local exchange business would better be able to enter, or would only be able to enter if a particular network element were available on an unbundled basis. Such entrants might on that basis plead impairment in the absence of unbundling. But if the economic evidence and market data show that some entrants are entering with their own facilities, then that evidence also suggests that, even if the absence of unbundling would disadvantage some individual competitors, it would not impair competitive entry itself. If policy is driven by the firms pleading impairment rather than by those entering with their own facilities, then the end result maybe to replace meaningful competition with an expanded group of less meaningful competitors.

40. Third, the process of rigorously defining a market for purposes of antitrust analysis applies to the question of unbundling. It is important, in deciding whether a network element needs to be unbundled, to examine both the competitive alternatives to the ILEC’s facilities as well as the ease of entry into provision of the element at issue. This analysis may require defining markets both in terms of product and of geography. If there are competitive providers of an element, or if the evidence shows that firms, either nationwide or in particular geographic markets, are successfully providing the elements for themselves and thus entering the market for the UNE at issue, then the case that competition is impaired without access to the incumbent’s

19 facilities fails. Careful definition and analysis of the markets for individual UNEs will thus be essential to unbundling policy that best promotes true competition and the ensuing consumer benefits.

41. One essential component of defining UNE markets will, as implied above, be geographic. It might be that there is no competitive entry or competitive UNE provisions in some geographic regions, but significant entry in others. Competitors should not be able to point to regions where there is no competitive UNE provision in order to maintain unbundling in regions where such entry is proving feasible. If UNEs were maintained on that basis, unbundling obligations would last so long as CLECs decided that there were some markets they did not want to enter or where they entered solely on a UNE basis. Even if lack of entry in some regions is the result of impairment (instead of because the market has unattractive profit potential), that localized impairment should not suffice to maintain unbundling obligations in markets where such impairment does not exist.

42. A critical, related point is that the Commission’s competitive analysis should not presume that lack of competition stems from entry barriers or other impairment. Entry into some markets without recourse to UNEs may be perfectly possible, but simply unattractive. Regulated end-user rates, cross-subsidies, and the slow process of state- by-state rate rebalancing all affect entry decisions. It is indeed one advantage for CLECs that they can choose their markets while ILECs cannot. Lack of entry due to regulatory factors or opportunity costs should not be converted into evidence of impairment. In such cases the ILECs bear costs that the CLECs choose not to, and to require unbundling in such circumstances simply exacerbates the regulatory distortions.

43. Finally, inter-modal rivalry is of central importance to the analysis of competitive impairment. If firms can provide substitutes for ILEC local exchange services over networks that bypass the telephone networks by using alternative kinds of facilities, then it is hard to make a case that entry in any way depends on unbundled access to

20 the ILECs’ networks. Even were it the case that entrants into the local market could not, for example, obtain conventional wireline loops without unbundling, there would be no impairment to competition if cable or wireless loops provided an alternative way to connect to customers. The Commission has itself emphasized the importance of inter-modal competition on the ILECs in the broadband context in finding that “the ILECs’ aggressive deployment of DSL can be attributed in large part to the deployment of cable modem service.”7 Cable and wireless telephony must therefore be considered in the analysis, and the inter-modal competition they provide to ILECs counted against the case for impairment. This analysis should be dynamic and also take account of technologies, like satellite-based broadband access, that are currently entering the marketplace and that are likely to add yet further competition in the foreseeable future.

III. Empirical Evidence of Entry and Competition in UNE Markets

44. This section addresses the evidence of facilities-based competition in the provision of several network elements. I will focus my discussion on switching and inter-office transport, but I will also discuss competition in providing both standard and broadband loops. In this section, I rely on data contained in the UNE Fact Report 2002 filed in this proceeding by BellSouth, SBC, Qwest and Verizon (“Fact Report”). The evidence presented in that report convincingly demonstrates that in the case of both switching and transport, there is substantial competition to the ILECs’ facilities and that such competition will only grow with technological changes already underway in the local exchange market. The data also show that the case for impairment without unbundled access to conventional voice loops is diminishing, and that it has vanished altogether with respect to high-capacity loops. My purpose in this section is not to reproduce the Fact Report, to which I refer the reader for a full discussion of current market data. It is instead to highlight certain key developments

7 Broadband today: A Staff Report to William E. Kennard, Chairman, FCC, at 27 (October 1999), available at http://www.fcc.gov/bureaus/cable/reports/broadbandtoday.pdf.

21 that demonstrate that the case for economic impairment in local exchange entry is diminishing rapidly overall and, in several key cases, has been eliminated altogether.

A. Switching Has Become Competitive and Will Become Even More So In The Near Future

45. Determining whether CLECs have substitutes for unbundled ILEC switches, such that they are not impaired without access to those ILEC switches, requires one to look beyond conventional circuit-switching technologies for voice calls. Whether or not CLECs have access to alternative circuit switches (which they in fact do), they have alternative technologies for switching local traffic. Defining the product to be examined in assessing impairment as “circuit switching for wire-line voice telephony” fails to capture the fact that much circuit-switched traffic consists of data, not voice, and that much switching of data and voice is packet switched, not circuit switched. In defining the market in which CLECs obtain the switching component of local exchange service, an important question is whether the decision to continue to require unbundled switching should take into account only wire-line, circuit-switched voice service or whether the market should be defined more broadly to include data services, packet switching, and wireless switching. As will be discussed below, the strength of the evidence on competitive, facilities-based switching is such that, even if the most limited definition of switching is adopted, there is still a compelling case for eliminating mandatory, unbundled access to ILEC switches. That case becomes all the stronger as one uses broader, more realistic product market definitions to assess performance of the switching market.

1. Circuit Switching has Become Competitive

46. An examination of the data on circuit switching of wire-line traffic demonstrates that competitors have no need for access to the ILECs’ “voice” switches. CLECs operate at least 1300 local voice switches today, over which they serve 16 million to 23 million lines. (Fact Report at II-1). Those switches are being deployed nationwide by

22 more than 200 CLECs. Importantly, most of the top CLECs use negligible amounts of unbundled switching and instead do almost all their circuit switching with their own equipment. (Fact Report at II-1) This last fact demonstrates that switch investment is something that new entrants both can, and overwhelmingly do, undertake on their own and without resort to ILEC networks.

47. The evidence is quite clear that facilities-based, competitive switching is not confined to CLECs that serve particular kinds of customers or particular geographic markets. While the majority of CLEC lines are business lines, CLECs are serving approximately 3 million residential subscribers over their own switches. (Fact Report at II-4, Table 2). Moreover, those switches are broadly deployed throughout the country. Almost half of all ILEC wire centers, for example, are served by at least one CLEC switch. (Fact Report at II-6). Significantly, those wire centers in which CLECs are using their own switches serve about 86 percent of ILEC customers. (Fact Report at II-1). A detailed discussion of CLEC switching is presented in part II of the Fact Report.

48. The empirical evidence thus weighs strongly in favor of removing switching from the list of network elements to be unbundled pursuant to the 1996 Act. Advocates of unbundled switching might nonetheless raise several objections to the economic significance of the data discussed above. Yet there is a compelling response to each such objection.

49. First, some might contend that evidence of CLEC-owned switches does not necessarily correspond to success by CLECs in entering the local exchange market. The data contradict any such assertion, however. As the Fact Report explains, at the end of 2001 CLECs were serving about 3 million residential lines and a much larger number of business lines with their own switches. (Fact Report at II-4). The fact that there is a large number of competitive switches and that CLECs can use them to serve residential customers, defeats any claim of impairment. The evidence makes clear

23 that switching is easily obtained and that competitors are not impaired if they must proceed without access to the ILECs’ switches.

50. Moreover, it should be noted that, once CLEC switches are in place, any excess capacity they have will make the market for switching services more competitive, not less so. If a CLEC purchases a switch and then fails to capture enough retail customers to use up capacity of the switch, then the CLEC can sell its excess capacity, or even its entire switch, to other entrants. Excess CLEC switch capacity would thus create an additional source of switching services for those entrants that for whatever reason might not want to purchase their own switches. Finally, the premise that local exchange competition has not followed from the introduction of competitive switches is false. As the data show, nearly 14 million local telephone numbers have been “ported” from ILEC switches to CLEC switches since 1999. Each ported number signifies a customer that the CLEC has won from the ILEC and now serves on its own switch. (Fact Report at II-5). And this ignores the new customers that the CLEC has won and now serves through an NXX code instead of a ported local number.

51. Second, some might argue that switching itself is too narrow product market definition for purposes of deciding unbundling. Switching alone, after all, is of little value if loops cannot successfully be connected to the CLEC’s switch. If collocation in ILEC wire centers is not possible, or if “hot cuts” of loops from an ILEC’s switch to a CLEC’s switch involve prohibitive costs or delays, then new entrants might have trouble switching traffic regardless of what facilities they own. The relevant market might thus be argued to consist of switching with necessary customer-transfer services. There are two pieces of market evidence that suggest little need for concern that switching may be thwarted by poor collocation or hot-cut performance. The most important fact is that hot-cut performance and collocation availability have both improved dramatically since the Commission’s 1999 UNE review. (Fact Report at App. H) The second fact, which probably results in part from the first, is that CLECs are in fact purchasing their own switches and thus acting in a manner that is

24 inconsistent with substantial concerns about hot-cuts or collocation services. Moreover, the hot cut issue is completely irrelevant for those competitors who do not need ILEC loops.

52. The important point is that real empirical data, not conjectural or theoretical concerns, should be the guide to Commission action when it comes to unbundling. Nothing more clearly demonstrates the feasibility of UNE alternatives than the fact that they actually exist and are being used successfully. Pointing to problems that allegedly existed in the past—and the large number of CLEC switches that existed at the time of the last UNE review suggests that there was no impairment due to switching even in the past—or that could speculatively exist in the future cannot defeat the reality of the marketplace and should not be permitted to take precedence over actual developments. To favor those firms that seek strategic advantage through unbundling when other competitors are investing in facilities risks undermining true competitive investment and the greater social benefits that it creates.

53. Third, advocates of unbundling might suggest that the data do not make a case for complete removal of switching from the UNE list because some wire centers are not competitively served, making unbundling necessary in those remote areas. This argument, too, fails for several reasons. Most notably, there is no evidence that competitive switching is difficult to obtain or provide in any region in which a CLEC actually chooses to pursue customers. Indeed, the broad dispersal of competitive switches makes clear that CLECs have been able to deploy their own equipment where they wish. Moreover, switching technology is now such that even very distant customers can be served from a single switch. The CLECs themselves have heralded the ability to engage in remote switching and to avoid placing a switch in a distant wire center or one in which they anticipate few customers, while still being able to serve those few, distant customers. (See Fact Report at II-9).

54. Finally, some might argue that the very data showing growth in CLEC-owned switches is evidence of the success of unbundled access to switching. The increase in

25 facilities-based switching might be argued to constitute the very transition that unbundling was intended to foster and to thus be evidence for continuing, rather than removing, requirements to unbundled switching. The evidence firmly contradicts any such claim that a lack of unbundled switching would undermine the transition to facilities-based competition. As the data in the part II of the Fact Report demonstrate, many of the largest CLECs use no unbundled switching at all. The transition to facilities-based switching is for many competitors thus “complete,” if it ever was necessary in the first place. The fact that some CLECs might prefer to continue obtaining switching on an unbundled basis is thus likely a result of their private business strategies and calculations rather than because foreclosure of that option would impair their further entry into local switching.

55. The data on local switching thus demonstrate convincingly that, even if the Commission were to adopt the most conservative and static product market definition—that of circuit-switched “voice” switching—there is a very strong case for removing local switching from the list of required UNEs. As the next section will show, that case become even stronger once one uses a more realistic and dynamic market definition for switching.

2. The Switching Analysis Should Include Packet Technology

56. The analysis above was restricted to circuit switching. But packet switching should be included in the relevant product market for purposes of analyzing the need for unbundled switching. Packet switching directly competes for current data traffic. Packet switching by cable modem and wireless services alone now substitute for about four percent of circuit switched calls, assuming that all broadband traffic would otherwise go over dial-up lines. (Fact Report at II-3). The substitution by which data calls that would otherwise go over the switched voice network are being routed through packet switches is growing rapidly. In the past three years, the number of known CLEC packet switches has increased tenfold, from 860 to more than 1700. (Fact Report at II-2). The FCC has already declared packet switching sufficiently

26 competitive that it should not be subject to mandatory unbundling.8 As those switches have come increasingly to compete directly with circuit switching, the latter, too, face genuine competition. Given that CLECs are not impaired without access to unbundled packet switching, the case for impairment without access to circuit switching vanishes as packet switches increasingly become a substitute for circuit switches.

57. While existing competition between circuit switches and packet switches is reason enough to include both in the same product market, the case becomes even more powerful when one looks only a short time forward. Packet-switched data lines are growing very fast. Much of this growth is over cable networks and needs no access to any part of the ILECs’ systems. More and more of total telecommunications traffic is thus being packet switched.

58. This substitution of packet for circuit switching is not limited to data traffic. Many data communications substitute directly for voice, as in the case of e-mail and instant messaging. But as the Fact Report details at part II.B, packet switching is also becoming increasingly suited to voice traffic itself. For example, many businesses are converting their internal telephone systems to voice-over-IP technology that sends voice traffic over a company’s intranet. As packet technology for voice develops, the substitution will grow dramatically. Data traffic, which dwarfs voice traffic, will drive the continuing shift to packet technology and will motivate migration of voice traffic to the same, increasingly dominant, packet switched networks. All of these changes, which are already in progress and which will transform the balance of switching technology in the foreseeable future, counsel considering packet and circuit switching as technologies that compete in the same market.

3. Switching Appears Yet More Competitive in Light of Wireless Competition

8 UNE Remand Order, ¶¶ 306, 308. Despite that correct conclusion, the FCC nonetheless retained a requirement that carriers must unbundle packet switching if the ILEC has deployed DLC, there are no spare copper facilities available, the ILEC has deployed its own packet switching, and the incumbent has not permitted a requesting carrier to collocate. Id. at ¶ 313.

27

59. Finally, it must be recognized for the purposes of any thorough competitive analysis that wireless services significantly reduce the need for a customer’s traffic to pass through any wireline switch, whether circuit or packet. Many residential customers who would otherwise purchase a second wired telephone line instead use wireless service, and a growing number are dispensing with wireline service altogether, relying entirely on wireless service instead. The number of wireless subscribers is fast approaching the number of wireline subscribers. There are now an estimated 130 million wireless subscribers versus about 190 million wireline subscribers. (Fact Report at II-3). Importantly, the former group is still growing fast while the latter is not. All wireless traffic is switched, and even if one eliminates from the count of wireless switches all those belonging to ILEC affiliates, there are now an estimated 950 independent wireless end-office switches deployed nationwide. Wireless already constitutes an estimated 12 percent of all phone calls in the U.S. (Fact Report at II-3), a percentage that is likely to grow as wireless data services grow and improve and as wireless subscriptions grow.

B. Inter-office Transport Has Also Become Competitive and Subject to Facilities- Based Entry

60. There are two principal reasons that inter-office transport no longer needs to be unbundled. First, there are now competitive sources of fiber transport. Second, the economics of inter-office transport are such that competitive local exchange carriers can economically build their own transport and would not be competitively impaired if they could not use the ILECs’ transport facilities. The empirical data demonstrate that CLECs have increasing options for purchasing transport from third parties and that they are also building their own transport facilities.

1. Competitive Transport Providers 61. In metropolitan areas, there is a group of firms who have entered the telecommunications market solely at the level of transport. These firms, sometimes

28 called competitive fiber providers, have constructed fiber rings that transport their end-user’s traffic both to long-distance carriers’ POPs and to ILEC central offices. Although the data is not yet clear on what percentage of customers can be served through such alternative transport networks, the fact that they are being built and expanded demonstrates that the transport market is subject to entry and that the ILECs’ transport facilities do not constitute an economic bottleneck to local exchange competition. In addition to the competitive fiber providers, a number of utility companies and interexchange carriers have substantial fiber networks that they use to supply transport to CLECs. (Fact Report part III, tables 6-7). This group of third-party fiber providers offers CLECs an important source of interoffice transport that neither obligates them to build their own facilities nor makes them dependent on the ILECs.

2. CLECs’ Transport Facilities

62. A conservative measure of whether CLECs are installing their own transport facilities can be had from the amount of fiber-based collocation in ILEC central offices. At present, ILEC data show collocated fiber in central offices serving 44 percent of all ILEC access lines. (Fact Report at III-3, table 1.) This evidence is compelling. If there is competitive transport to central offices through which an entrant can reach nearly half of the incumbents’ customers, then it is unlikely that there is any impairment to entry into those markets without access to the ILECs’ transport lines.

63. In addition to what the data show about where CLECs have already obtained fiber- based collocation, the evidence strongly suggests that entrants have the ability economically to construct transport facilities in many additional wire centers. The fact that CLECs have built competitive transport to many ILEC central offices with high concentrations of business lines suggests that they economically could do so to the rest of those offices where fiber-based collocation does not yet exist. (Fact Report at III-4, table 3). The data strongly indicate that CLECs are not impaired in their ability to obtain interoffice transport in the absence of unbundling for most of the lines they have demonstrated any intent to serve.

29

64. The conclusion that CLECs no longer face any impairment in obtaining interoffice transport becomes all the stronger when one considers that the fiber-based collocation measure of transport competition does not even account for the traffic that bypasses the ILECs’ networks altogether. There are now an increasing number of firms providing alternative points of traffic concentration in most major markets and a growing proportion of competitive transport runs between such competing interconnection points rather than through ILEC wire centers. The growth of such facilities is documented in detail in part III of the Fact Report.

65. In the end, transport has become a market populated by various, overlapping options for carriers. In addition to the incumbents’ network, there now exists a combination of CLEC fiber collocated at ILEC wire centers, CLEC fiber collocated at alternative points of traffic aggregation, and third party fiber facilities. Taken together, these alternatives demonstrate that competitive transport is no longer dependent on CLECs’ access to the ILECs’ facilities.

C. Loop Competition Reinforces Competitiveness of Other UNE Markets

66. In the three years since the Commission’s last UNE review there has been a significant increase in competitive provision of loops. The degree of such competition varies by geographical area and by type of loop and customer. Changes in the loop market have two important consequences for unbundling policy. The first is a direct effect on loop unbundling: for certain kinds of loop facilities, specifically high- capacity loops, the market data show that unbundling is no longer necessary. The second effect is less direct: loop competition, even where it is not sufficient to warrant a repeal of unbundling, adds to the proportion of traffic that is moved off of the ILECs’ other network facilities such as switches and transport links. In other words, loop competition not only weighs against unbundling of loops themselves, but strengthens the already compelling case for eliminating unbundling of switching and transport.

30

1. The Market for High-Capacity Loops is Competitive

67. The most significant facilities-based entry into customer access lines has been in the market for high-capacity loops. Numerous CLECs have constructed their own DS-1 and higher lines to serve buildings where businesses are concentrated. CLECs serve between 11 and 19 million business lines over their own last-mile facilities, many of which are high-capacity loops. (Fact Report at IV-2). The above figures understate the true state of competition in high-capacity loops. They do not count the facilities of all CLECs and do not include loops owned by third party fiber providers and leased by CLECs.

68. As in the case of competing inter-office transport, the high-capacity loops that already exist form the base off of which those facilities may be expanded incrementally and economically to areas where businesses are less concentrated and to the premises of smaller customers. Existing facilities also demonstrate the feasibility of competing loops where similar high-capacity customers exist but are not yet competitively served. In addition, special access provisions offer an alternative to unbundling for obtaining high capacity loops for those firms that do not wish to build out their own facilities.

69. Whereas CLECs have proven willing and able to construct their own high-capacity loops, they have made little use of unbundled high-capacity lines. As the Fact Report shows at IV-7, table 2), CLECs have made almost no use of unbundled loops with capacity higher than DS-1 and serve most of their DS-1 customers with their own facilities rather than over unbundled loops.

70. While the Commission also needs to carefully evaluate the need to unbundle other types of loops in circumstances where there are obvious competitive alternatives (such as in areas whose cable companies are providing telephone service over their own networks), the above facts make an especially strong case for eliminating the

31 unbundling of high capacity loops. There is clearly no difficulty in providing service over such lines even without any resort to the ILECs’ facilities. It would turn the idea of “impairment” on its head to maintain unbundling for high capacity loops; for to do so would be to maintain a back-stop alternative for CLECs that they do not need economically to provide the facilities at issue without competitive disadvantage. As part I of this paper discusses, maintaining such an option where it is not needed may have significant costs for consumers and for competition.

D. Inferences to Be Drawn From the Empirical Evidence

71. The empirical evidence presented in the Fact Report provides a clear picture of the emergence of competitive facilities in all the most important UNE markets. The evidence against impairment is extremely strong for switching, for high-capacity loops, and for interoffice transport. Yet in each of the UNE markets just mentioned, there may be some classes of end-user customers and some geographic areas that are not served over competitive facilities. In other words, some strict standard of “ubiquity” might not be met for even those network facilities that are easily supplied on a competitive basis. If unbundling policy is to be economically sound and to benefit consumers and competition, it is important that such perceived gaps in UNE competition not overshadow the competitive significance of entry where it has occurred and thereby improperly drive unbundling policy. There are two broad reasons that greater weight should be given to the evidence of where UNE competition has developed than to the evidence of where it has not.

72. First, the fact that CLECs are in some cases supplying their own facilities or procuring them from third parties demonstrates that competitive provision of the element at issue is economically feasible. That in itself weakens any argument for impairment. When a substantial number of CLECs are deploying facilities other than UNEs, and when those facilities serve or potentially serve a large proportion of access lines, then the impairment argument is not merely weakened but unsupportable. In such circumstances, the widespread use and availability of competing facilities should

32 raise a presumption that ubiquitous deployment is feasible. Under such circumstances, CLECs’ decisions not to deploy their own facilities are likely driven either by decisions not to serve certain end-user customers or by preferences for unbundled access even though lack of such access would not be a true competitive impairment. It bears emphasis that the point of unbundling is not to free CLECs from incurring the same costs as the ILECS or undertaking the same activities the ILECs must engage in to provide service. The issue is whether the CLECs are competitively impaired compared to the ILECs without unbundling, not whether unbundling is advantageous compared to other entry paths.

73. Second, an absence of competitive facilities or continued use of UNEs may be the product of many factors that have nothing to do with the ability of CLECs economically to supply their own facilities. Regulation of end-user rates will make some customers more desirable than others and affect the entry strategies of competitive carriers. As already discussed, the rates for unbundled network elements will affect the comparative advantage of entering over one’s own facilities or over the ILECs’ networks. Predictions about changes in technology or in the services that customers demand will also influence a CLECs’ investment decisions. This list is not intended to be exhaustive, but merely to point out that there are numerous forces other than impairment that can explain gaps in the provision of competitive local exchange facilities.

74. For the above reasons, the Commission should be very cautious about accepting arguments based on lack of “ubiquity” in support of continued unbundling. The existence of competing facilities unambiguously demonstrates the feasibility of facilities-based entry. The absence of such facilities in some markets or for some customers, when competing facilities are elsewhere widely available, only questionably and ambiguously suggests impairment. Where the evidence shows facilities-based entry, the logical inference is that entry is feasible in markets with similar characteristics but where CLECs may not yet have chosen to enter. The

33 burden should rest with the CLECs to demonstrate that lack of entry is indeed due to specific market characteristics that create impairment.

75. As the previous section of this declaration discussed in detail, there are potentially high social costs of unwarranted unbundling. The economic inferences that drive unbundling policy should be therefore grounded in the empirical evidence of the development of significant, even if not highly ubiquitous, competition in a network element market. As the earlier discussion explained, such evidence should presumptively counsel the repeal of mandatory unbundling of that element. The evidence surveyed in this section and set forth in detail in the Fact Report convincingly support a strong presumption against further unbundling of switching, interoffice transport, or high-capacity loops.

IV. Conclusion

76. The empirical evidence of local exchange competition and of the UNE alternatives available to CLECs soundly rebuts claims of impairment with regard to switching, inter-office transport, and high-capacity loops. Given the substantial risks that unbundling creates for telecommunications consumers and for the competitive process, the Commission should adopt a strong presumption against unbundling of these elements. It should not be enough to prove impairment for a CLEC to show that UNE alternatives are not in fact being used in a particular market. Where the empirical evidence shows that non-UNE entry could occur unimpaired in a particular market, perhaps because it has so occurred in markets with similar characteristics, the inference should be drawn against the need for unbundling. Without such reasonable inferences, unbundling will occur where impairment does not truly exist. Such an outcome will reduce the scope of competitive benefits produced by the local exchange markets, punish CLECs or third-party providers who have invested in their own facilities, and compromise the ultimate economic objectives of the 1996 Act.

Attachment B.

3. Advanced telecommunications services are being offered, and will increasingly be offered,

by firms that formerly operated in distinct markets and industries (e.g., traditional telephone

and cable television service) as well as new firms seeking to share in this apparently huge

- 3- A.E. Kahn/T.J. Tardiff

potential market. These new offerings include broadband services—such as high-speed

access to the Internet, currently provided mainly by cable modems and digital subscriber

lines (DSL)—which have the potential to provide new ways for consumers to acquire

information, audio and video entertainment and engage in business transactions. They also

give businesses new ways of reducing their costs and of reaching consumers with products

and services, new and old. These benefits to consumers and businesses are likely to be very

large: some research suggests hundreds of billions of dollars annually.1

4. These broadband services are truly new, especially for residential and small business

customers. By the end of 1998, the FCC counted fewer than 400,000 subscribers—a

penetration rate of well under one percent—some 350,000 using cable modems and only

25,000 DSL. 2 Thereafter, in each of the next two years, residential and small business

subscribership increased about four-fold, reaching a total of about 6 million by the end of

2000.3 4 Some analysts have projected subscribership of 30-40 million by 2005, with cable

1 See, for example, Robert E. Litan and Alice M. Rivlin, “Projecting the Economic Impact of the Internet,” American Economic Review, Vol. 91, No.2, 2001, pp. 313-317 and Robert W. Crandall and Charles L. Jackson, “The $500 Billion Opportunity: The Potential Economic Benefit of Widespread Diffusion of Broadband Internet Access,” July 2001. 2 Federal Communications Commission, Deployment of Advanced Telecommunications Capability: Second Report, CC Docket No. 98-146, August 2000. 3 The respective shares of cable modems and DSL were 71 and 29 percent at the end of 1999 (Federal Communications Commission, Office of Plans and Policy, Telecommunications @ the Millennium: The Telecom Act Turns Four, February 8, 2000) and some two-thirds and one-third, respectively, at the end of 2000, with competitive local exchange carriers constituting some 20 percent of the latter group at the end of both 1999 and 2000.

modems maintaining a narrowing lead in market share.5 The FCC’s second Advanced

Services report also describes the inroads made by wireless and satellite services. The clear

prospect is a competitive free-for-all among different suppliers and technologies, with the

ultimately victorious ones far from clear and only consumers clear winners.

5. While broadband subscribership has continued to grow in 2001, the rate of that growth has

declined markedly in not only percentage but also absolute terms. Moreover, the drop-off

has been disproportionately large in the case of DSL as contrasted with cable modems.6

While the total number of residential broadband subscribers added per quarter declined 20

percent—from 1.5 million in the fourth quarter of 2000 to 1.2 million for the first half of

2001—the decline in the new subscriptions to DSL was 35 percent (from 0.7 million to

0.45 million) and to cable modems only 7 percent (from 0.8 million to 0.75 million). The

weakening of the U.S. economy doubtless explains part of the overall deceleration; the fact

that growth rates for the more heavily regulated DSL services have experienced a much

larger decline suggests, however, that current regulations may also be part of the

explanation.

6. Whether the full potential of broadband services is realized depends on whether firms that

must make huge investments to develop and upgrade the requisite networks have the

opportunity to earn returns commensurate with the risks they will face. The amount and

type of regulation will be an important determinant of those opportunities. As we explain

in more detail below, any regulation of new services is problematic, because it increases the

5 Verizon, Broadband Fact Report, December 19, 2001. 6 Ibid., pp. 16-17.

- 5- A.E. Kahn/T.J. Tardiff

cost and decreases the attractiveness of offering them. By the same token, relaxing

regulation where it is no longer needed can unlock this potential. For example, as we

describe in detail below, wireless was successful—providing benefits estimated at $25-$50

billion annually—even though it was regulated through the mid-1990s; since its

deregulation at that time, subscribership has increased four-fold, with a commensurate

increase in consumer benefits.

7. While both Congress and the FCC have generally recognized that the enormous potential

will be much more rapidly and fully realized through competition in the market rather than

a regulatory regime, there is a gaping exception to this recognition. While the FCC has

generally taken a hands-off position with respect to both the Internet and most means of

providing access to it, it has at the same time extended to the broadband services of

incumbent local exchange carriers (ILECs) its regulations designed to promote competition

for traditional local exchange services. The purpose is, of course, the same as the purpose

of the Telecommunications Act in requiring ILECs to make unbundled network elements

available, at favorable wholesale prices, in the belief that competitive local exchange

carriers (CLECs) would be “impaired” in their ability to compete in downstream markets

without such access.

8. Whatever merits regulations such as these have in facilitating efficient competition for

traditional telephone services, they are both unnecessary and counterproductive when

applied to broadband. As for the former, the essential premise underlying these

requirements—namely, the necessity of CLECs having access to the facilities of the

ILECs—is invalid in the broadband market. Not only are there alternative sources, as the

- 6- A.E. Kahn/T.J. Tardiff

FCC has itself conceded; the ILECs are not the dominant suppliers—they have been and

remain markedly behind cable modem services. And, on the other side, maintaining,

extending, or even keeping open the option of applying regulation asymmetrically only to

ILECs will not only dampen their incentives to roll out these services quickly and to

introduce new methods of broadband access; it also risks artificially preserving the

dominant position of the incumbent cable modem providers.

9. In particular, because it is very difficult, perhaps impossible, to forecast how competition

for broadband services will evolve (what technologies will emerge, how successful each

will be, what proportion of consumers will choose to subscribe, and how frequently and for

what purposes they will use the services), basing regulatory policies on assessments of

whether the present deployment is “fast enough,” would be a fruitless exercise. No one can

possibly know the ultimate size of the market and how it will be supplied. The task of

policy is to remove all remedial hindrances to the competitive market’s giving us the

definitive answers.

7 II. ECONOMICS OF NEW SERVICES

10. New services, particularly those requiring large investments and/or new technology, offer

the prospects of large benefits, but at significant costs and with unusual degrees of risk.

The benefits are large precisely because of their novelty. For example, Crandall and

Jackson have estimated that wide scale penetration of broadband services (with broadband

- 7- A.E. Kahn/T.J. Tardiff

becoming almost as ubiquitous as ordinary phone service) would provide economic benefits

of $400 billion annually in the form of new capabilities, such as shopping, commuter travel

and home entertainment.8

11. Whether the widescale penetration that delivers such benefits will become a reality depends

on potential suppliers—ILECs, cable operators, wireless broadband providers—making the

requisite large investments, with no guarantee that their particular technology will prevail in

competition with others or that consumers will sufficiently value the services it makes

possible. These will include the large investments not only in the electronic equipment

necessary to roll out more of their present DSL services over their existing copper loops but

possibly the even larger ones in both electronics, fiber optic and wireless facilities capable

of providing for greater capacity to carry information.

12. Were it not for the long legacy of telecommunications regulation—necessitated historically

by the monopoly of the ILECs in traditional telephone service generally and local access in

particular—the proper regulatory treatment of broadband services would be crystal clear:

there would be none. The newness of the service, its reliance on risky technologies, the

rapid expansion of the market and the leading position of unregulated suppliers all strongly

suggest that the FCC’s general disposition to keep its hands off the Internet has been

fundamentally correct. The investments that the Telecommunications Act seek to

encourage are not of a routine character such as may be required to provide plain old

telephone service, but extremely costly and risky, both commercially and technologically.

As for the former, it is useful to recall the exuberant expectations at AT&T about the

8 Op. cit.

- 8- A.E. Kahn/T.J. Tardiff

potential of Picturephone some 35 years ago. While until recently analysts had expected

broadband subscription to grow at rates resembling those of wireless a decade earlier, with

comparable enormous benefits to the public,9 the recent downturn in growth suggests that

establishing the correct broadband policy may be a prerequisite for realizing its full

potential. At the same time, there are very large risks about which technology will prevail:

it is important to remind ourselves that those benefits are much clearer in hindsight than at

the beginning of that decade, as is clearly suggested by the willingness of AT&T to

surrender this particular business to the RBOCs at the time of divestiture, its more recent,

hugely costly cable company acquisitions and its present attempts to sell them off. As for

the technological uncertainty, how many times over the last several years has the consensus

view changed about what method of transporting telecommunications signals will prove to

be the successful one?

13. Under a proper conception of effective competition, the general rule is that neither new

services nor the underlying facilities that produce them should be subject to regulation. The

conception of monopoly in the offer of truly new services is a virtual oxymoron. New

services offer customers additional alternatives not available to them previously. Their

introduction is fundamentally a competitive rather than a monopolistic phenomenon, even

though they may be distinctive and the innovator may be in a position to earn supernormal

profits from them. To deny an innovator the rewards of being first would inhibit

innovation, and it should not matter for these purposes whether the innovator is an

incumbent telephone company, an incumbent cable television provider, or a new entrant. A

half-century ago, Schumpeter10 eloquently expounded—and generalized—the same

underlying principle: the “perennial gale of creative destruction” that constitutes the most

creative form of competition in a capitalist economy consists, at its essence, in the perpetual

process of creation and erosion of monopoly positions achieved by innovation, with the

prospect of the monopoly that rewards successful innovation providing the essential

incentive for innovators and imitators alike. Transient market dominance and monopoly

pricing are an essential part of the process:

The introduction of new methods of production and new commodities is hardly conceivable with perfect¾and perfectly prompt¾competition from the start. And this means that the bulk of what we call economic progress is incompatible with it. As a matter of fact, perfect competition is and always has been temporarily suspended whenever anything new is being introduced ¾automatically or by measures devised for the purpose¾even in otherwise perfectly competitive conditions (1950, p.105).

14. The more innovative the investments contemplated, the greater the uncertainties, both

technological and commercial, the greater the risks, the more important is the prospect of

the investor’s exclusive enjoyment of the fruits of the ventures that turn out successfully.

This proposition and the way in which the FCC’s sharing rules conflict with it are most

incisively spelled out by Justice Breyer, in his concurring opinion in the Iowa Utilities

Board case:

[A] sharing requirement may diminish the original owner’s incentive to keep up or to improve the property by depriving the owner of the fruits of the value-creating investment, research, or labor….Nor can one guarantee that firms will undertake the investment necessary to produce complex technological innovations, knowing that any competitive advantage deriving from those innovations will be dissipated by the sharing

requirement…..Increased sharing by itself does not automatically mean increased competition. It is in the unshared, not in the shared, portions of the enterprise that meaningful competition would likely emerge. Rules that force firms to share every resource or element of a business would create, not competition, but pervasive regulation, for the regulators, not the marketplace, would set the relevant terms.11

15. As in the case of broadband, the major contribution of wireless has not been its reduction in

the cost of existing ordinary telephone service,12 but its offer of a new service that allows

consumers to communicate in ways virtually unavailable previously—for which consumers

were willing to pay high prices in the early years and in explosively growing numbers as

prices declined but remained still at premium levels—every year since it was introduced.

16. Economists measure the benefits from a new product or services as the difference between

what consumers pay and what they would be willing to pay at the point that they were

indifferent between using the service and spending the money elsewhere. For example, the

early adopters of cellular service paid several hundred dollars for the phone itself and prices

considerably higher than today’s for usage.13 Now, these same subscribers can pay less for

a service that is also probably of higher quality. Accordingly, the benefit from this

phenomenon is at least as large as the difference between what they used to pay for the

amount they used and what they pay today for that old amount, and of course it is

enormously increased by the difference between the successively declining prices that

successive increments of customers would have been willing to pay and the low prices that

they more or less uniformly pay today.

11 AT&T Corp. v. Iowa Utilities Board, 119 S. Ct. 721, 752 (1999) (Breyer, J. concurring in relevant part). 12 In fact, it has been only fairly recently that prices have declined to the point where wireless service has become a substantial substitute for ordinary service.

- 11- A.E. Kahn/T.J. Tardiff

17. Jerry Hausman estimated the benefits of wireless services to consumers in 1994 at $25 to

$50 billion annually,14 or between 1.75 and 3.5 times the annual revenues of about $14

billion. 15 And both have exploded since then: subscribers have increased from about 25

million to over 100 million and revenues from $14 billion to over $50 billion annually.16

This explosion coincided with two events that substantially relaxed regulatory burdens on

wireless providers: (1) the Omnibus Budget Reconciliation Act of 1993, in which Congress

deregulated the industry to a great extent, and (2) the increase in the number of providers

that the availability of the new PCS spectrum permitted. Applying Hausman's calculations

to current volume shows that the annual benefits have grown to a range of $85 billion to

$170 billion.

13 The FCC reports that the average revenue-per-subscriber declined from about $97 in 1987 to about $45 in 2000. 14 Jerry A. Hausman, “Valuing the Effect of Regulation on New Services in Telecommunications,” Brookings, 1997. Similarly, Rohlfs, et al. estimated the social cost of the 10 to 15 year regulatory delay in licensing cellular systems at more than $86 billion–about 2 percent of GNP in 1983, when cellular service began. Jeffrey H. Rohlfs, Charles L. Jackson, and Tracey E. Kelley, “Estimate of the Loss to the United States Caused by the FCC’s Delay in Licensing Cellular Telecommunications,” National Economic Research Associates, November 4, 1991. 15 The major determinant of the relation between revenue and benefit is the price elasticity, with the multiple decreasing as the elasticity increases. This is explained by the fact that when elasticity is high, consumers would be willing to pay little more than the current price. 16 This expansion appears to be the result of both lower prices and competition shifting the demand curve outward by making services available to more consumers, improving the quality of services, and the like. In fact, the demand curve shift seems to be at least as powerful as the price reduction. For example, if we treat the 25 percent reduction in revenue per subscriber as a price decrease and use Hausman’s elasticity of –0.5, then over 80 percent of the growth in volume after 1994 can be attributed to the demand curve shift and less than 20 percent to the price reduction. If instead we take as a measure of the decrease in prices the drop from $0.57 in 1994 to $0.21 in 2000 (Thomas J. Sugrue, “Sixth Annual CMRS Competition Report, Opening Remarks,” June 20, 2001), the increase in demand and price reduction share equally in explaining the total expansion of sales. A ma jor benefit of the increased competition since 1994, in addition to its having reduced prices to existing consumers, has been its expansion in the reach of these new services to a much larger customer base.

III. THE CURRENT ASYMMETRICAL REGULATION OF BROADBAND SERVICES INHIBITS INNOVATION AND HARMS CONSUMERS

18. The universal prescription of economists, we submit—other considerations aside17—would

be that regulators not impose economic regulation on the provision of risky, innovative

and/or new services such as broadband. In contrast, the present system has the anomalous

characteristic that the leading suppliers, cable operators, are not regulated, while the

competitors striving to catch up with them—in both cases endeavors that require very large

and risky investments—are still regulated on the basis of what a regulatory agency says is

“cost” plus a “reasonable” profit. In addition to the absurdity of shackling a competitor

running in second place, the injuries to consumers from perpetuating such asymmetrical

regulation are four-fold. First, by increasing the costs and risks of only one type of

competitor—in effect imposing a tax on particular sources of supply—it makes it less likely

that the services those competitors are uniquely qualified to offer will make it to the market,

depriving consumers of the possibly enormous benefits of such offerings. Second, even if

the broadband services offered by alternative providers prove to be close substitutes,

handicapping one group could prevent the lower-cost supplier from taking over the share of

the market that it would otherwise obtain. Third, the regulatory advantage enjoyed by the

cable operators could give them an advantage in the provision of services other than

broadband—such as video—thereby weakening and conceivably distorting the competition

in the supply of such complementary services. Fourth, the discouraging effect of the

17 We cannot of course ignore the fact that some economists are, nevertheless, opposing the deregulation of these services, particularly as it applies to the incumbent telephone companies, in the interest of preserving competitive opportunities for downstream rivals. We address ourselves specifically to that purpose of the Telecommunications Act in pars. 25-38, below.

- 13- A.E. Kahn/T.J. Tardiff

Commission’s regulation of the ILECs’ broadband offerings is not confined to risk-taking

innovations by them; it is equally destructive of the other part of the process of competitive

innovations—the efforts of rivals of the successful innovator, by their own efforts, to invent

around and surpass the originator.

19. The current broadband regulatory scheme as applied to ILECs appears to be designed not to

provide incentives for them to compete against cable modems and other facilities-based

providers but to provide CLECs an opportunity to get a piece of the action by free-riding on

their facilities. The fact is, however, that the greater public benefits flow from facilities-

based competition than from the efforts of competitors reselling the ILEC facilities, taking

advantage of regulatorily-created opportunities; and it is precisely that facilities-based

competition that the present rules both distort and discourage.

A. Cable Modems are Essentially Unregulated

20. In both its public pronouncements18 and its specific rulings, the FCC has consistently

maintained a hands-off-the-Internet position with regard to cable modem services,19 a

position it established early and articulated clearly in approving AT&T’s acquisition of

TCI, then the largest cable television company. The issues were poignantly posed by the

plans of AT&T for a multi-billion dollar upgrading of the TCI cable in order to provide

local, Internet and advanced video services; by the mounting pressures on the Commission

18 See, for example, “’Open Access’ Review Would be ‘Premature,’ Kennard Tells Dingell,” Telecommunications Reports, January 3, 2000, pp. 5-6 and Federal Communications Commission, In the Matter of Inquiry Concerning High-Speed Access to the Internet Over Cable and Other Facilities, Notice of Inquiry, GEN Docket No. 00-185, September 28, 2000, par. 4. 19 The FCC has undertaken an ongoing investigation of this policy, apparently motivated at least in part by open access rulings by local governments and differing interpretations by federal courts. Ibid., par. 14.

- 14- A.E. Kahn/T.J. Tardiff

by competitors and public agencies to condition its approval of the merger on AT&T’s

giving competitors access to those facilities—presumably at FCC-determined rates; and by

the equally costly and risky plans of the incumbent telephone companies to compete in

these same markets by digitalizing their subscriber access lines. AT&T strenuously resisted

the proposals to impose such a condition upon it.20 As its experts argued, in our view

correctly:

It would be against the public interest to subject the parties’ last mile broadband data transport facilities to any form of regulation at this time….There are many competitors, including the ILECs, that are actively developing broadband transport services…The xDSL services that are currently being deployed by the incumbent LECs alone constitute a significant and attractive commercial alternative to the internet cable services that TCI and others offer…The] demand to unbundle broadband transport will engender intrusive regulation of an emerging new service that requires massive entrepreneurial investments and whose marketplace success is far from assured…Forced unbundling with its attendant regulatory uncertainty would likely slow down the investment in the development of broadband last mile investment. Investing under the shadow of uncertain regulatory rules in an innovative service exacerbates the already substantial risks associated with that investment.21

The FCC concurred, presumably in the belief that imposition of such a sharing obligation

would be incompatible with Congress’s deregulation of the cable companies, with the need

to encourage costly investment in upgrading their telecommunications capabilities and,

therefore, with Schumpeterian competition. In its later approval of AT&T’s acquisition of

Willig, attached to AT&T’s and TCI’s Joint Reply to Comments and Joint Opposition to petitions to Deny or to Impose Conditions, In the Matter of Joint Application of AT&T Corp. and Tele-Communications, Inc. for Transfer of Control to AT&T of Licenses and Authorizations Held by TCI and its Affiliates or Subsidiaries, CS Docket No. 98-178, November 13, 1998. Ordover and Willig make no effort to reconcile their compelling argument here that government restrictions can stifle innovation incentives with their previous advocacy of TELRIC pricing for access to ILEC networks.

- 15- A.E. Kahn/T.J. Tardiff

MediaOne, the FCC once again rejected mandatory sharing, emphasizing the competition

among both broadband access providers and Internet Service Providers (ISPs) as a major

part of its rationale:

[W]e find that there is significant actual and potential competition from both broadband service providers and from unaffiliated ISPs that may gain access to the merged firm’s cable systems.22 The evidence of growing competition from both alternative broadband providers and unaffiliated ISPs gaining access to cable and other broadband networks indicates that any action taken by the merged firm to disfavor unaffiliated broadband content and applications providers is likely to threaten the networks’ ability to attract and retain customers.23

21. The FCC currently regulates the ILECs’ broadband services in two ways: (1) it requires that

the prices they charge their end-user customers and Internet Service Providers (ISPs)24 be

cost-based and (2) it requires them to make certain parts of their networks available to

competitors at prescribed wholesale prices. Indeed, if anything, these unbundling

requirements and concomitant pricing rules become even more onerous when the ILECs

contemplate upgrades to their networks that would both extend broadband services to more

customers and provide the capability for more services (e.g., video). The contrast with the

explicit exemption of the dominant cable modem services could not be more glaring.

22. While the continued application of traditional regulatory pricing standards to ILECs’ retail

broadband prices (for services offered to end-users and ISPs)25 prescribes the rate at which

22 Federal Communications Commission, In the Matter of Applications for Consent to the Transfer of Licenses and Section 214 Authorizations from MediaOne Group, Inc., Transferor to AT&T Corp., Transferee, Memorandum Opinion and Order, CC Docket No. 99-251, June 6, 2000, Par. 116. 23 Ibid., par. 123 24 Indeed, while ILECs are required to provide services to ISPs at regulated prices, the FCC has not even required that cable television providers provide access to ISPs at any price. 25 Federal Communications Commission, In the Matter of GTE Operating Companies GTOC Tariff No. 1, GTOC Transmittal No. 1148, Memorandum Opinion and Order, CC Docket No. 98-79, October 30, 1998, par. 32.

- 16- A.E. Kahn/T.J. Tardiff

they are permitted to recover the large investments needed to provide these services,

competitive providers are free to set prices as market conditions permit or dictate. And the

ILEC must offer any services that it sells directly to end users also to competitors, at a

prescribed resale discount.

23. To date, the FCC has considered the facilities used by ILECs to provide broadband services

to be telecommunications services, and thus potentially subject to being offered on an

unbundled basis to competitors. The requirement that the ILECs actually unbundle the

facilities that provide broadband services and make them available to competitors is subject

to the FCC’s finding that particular elements satisfy the “necessary” and “impair”

requirements of Section 251 of the Telecommunications Act. In that event, they become

subject to the pricing standard specified in Section 252, which the FCC has interpreted to be

its blank-slate total-service long-run incremental cost (TELRIC). To date, the Commission

has made the following pertinent unbundling decisions:

· Because the electronics necessary to provide broadband capability over copper loops are widely available and easy for CLECs to deploy, it declined to order that packet switching and DSLAMs be unbundled, under at least some circumstances, when customers are served by copper loops.26

Federal Communications Commission, In the Matters of Deployment of Wireline Services Offering Advanced Telecommunications Capability, Second Report and Order, CC Docket No. 98-147, November 9, 1999, par. 21. 26 Federal Communications Commission, In the Matter of Implementation of the Local Competition Provisions of the Telecommunications Act of 1996, Third Report and Order and Fourth Notice of Proposed Rulemaking, CC Docket No. 96-98, November 5, 1999, pars. 306-317. Even in this case, the Commission’s action could be viewed as tentative in that it qualified its action with the phrase “at this time (par. 306),” strongly suggesting that it reserved the right to unbundle in the future.

- 17- A.E. Kahn/T.J. Tardiff

· When, however, ILECs offer DSL services over loops that are part copper (distribution) and part fiber (feeder) and they are not able to offer collocation space in their remote terminals, they must unbundle their DSLAMs and packet switches.27 · Shortly after refraining from mandatory unbundling of the electronic equipment that provides DSL services, the FCC did require the ILECs to unbundle the high frequency part of a loop and offer it at low regulated prices to CLECs wishing to offer DSL—thereby sharing that line with the ILEC providing ordinary voice service.28

24. The situations in which these asymmetrical unbundling obligations impinge most heavily

on the ILECs are precisely the ones in which those obligations dampen their incentives to

upgrade their networks in order to extend broadband services to more customers and

enhance the offerings to all of them—namely, the ones involving application of

technologies other than existing copper loops. They do so: (1) by effectively allowing

CLECs to share in the rewards from the new investments while paying only bare-bones

TELRIC prices for that privilege, (2) imposing the costs of accommodating those CLECs—

for example, the costs of increasingly sophisticated operations support systems—only on

the ILECs and not on their other facilities-based competitors, and, (3), in particular,

effectively perpetuating mandatory unbundling as new technologies move potential points

of interconnection out of the central office (where space is more available than at other

27 Ibid., par. 313. At the time of the order, the most current ARMIS data (1998) showed that about 17 percent of the lines in Verizon’s (pre-GTE merger) territory had fiber feeder. In the two years since then, such lines have accounted for 75 percent of the growth in the total. 28 Federal Communications Commis sion, In the Matters of Deployment of Wireline Services Offering Advanced Telecommunications Capability and Implementation of the Local Competition Provisions of the Telecommunications Act of 1996, Third Report and Order in CC Docket No. 98-147 and Fourth Report and Order in CC Docket No. 96-98, December 9, 1999. In making that determination, the FCC employed an extremely narrow market definition—confining it to customers that want ordinary voice and DSL service over a single line (par. 39). And in determining what types of entrants would be “impaired” without line sharing, the FCC focused on special-purpose providers that choose to piggyback on ILEC voice customers. Ironically, in light of the fact that parties opposed to line sharing had argued that (1) a CLEC could choose to exploit the same economies of scope as an ILEC by buying a loop and offering both voice and DSL and (2) the DSL-only CLEC could cream-skim above cost voice services by transporting them over its packet switches, the FCC admitted

points) and farther into the network, where collocation arrangements are decreasingly

available and/or more costly.29

B. The Impropriety and Harmful Effects of Extending Mandatory Sharing to ILEC Broadband Facilities

25. There is no disagreement with the proposition, embodied in the Act, that incumbent

telephone companies should be required to make available to their competitors at a

reasonable cost-based price preexisting facilities, inherited from their franchised

monopolies, that are truly essential if the challengers are to compete with them. To the

extent, however, that (1) it is economically feasible for competitors to obtain access to such

facilities or practical substitutes from other sources or (2) the incumbents acquired or

created them in competition with other providers, and, especially (3) if that acquisition has

involved or continues to involve costly, risky innovation, enforcement of an obligation to

share them or the advantages they confer with rivals can be anticompetitive.

26. In the case of broadband services, there is a strong case for the position that the obligation

to share should be confined to essential facilities, strictly defined. The essence of

competition is the attempt to develop and exploit the competitive advantages that

successful innovation provides; to require their sharing in instances in which that quest has

been successful, particularly where the quest involved big risks, would therefore discourage

competition itself.

that these DSL-only entrants would indeed be able to attain scope economies through the cream-skimming that the ILEC opponents had identified (par. 57) 29 This is because under the FCC’s rules the offer of collocation exempts an ILEC from obligations to unbundle their DSLAMs and packet switches; but these recent developments moving interconnection points further into the network make the collocation exemption decreasingly available to them.

- 19- A.E. Kahn/T.J. Tardiff

27. Some have argued for a less strict standard in the context of the introduction of competition

into public utility industries: that typically an incumbent company not only will control

some facilities truly “essential” to its rivals but will also enjoy economies of scale or scope

not because of superior enterprise on its part but merely because of its inherited franchised

monopoly, and that requiring it to share the benefit of those facilities with rivals at a

compensatory price would therefore not entail penalizing successful competitive efforts.

By exactly the same logic, however, there is no basis for applying the sharing requirement

to the subscriber access facilities of the local telephone companies and not to the access

lines of their cable competitors, whose “monopoly” of which is similarly attributable to

their historical status as franchised local monopolists.

28. Moreover, the somewhat more liberal sharing requirement of the telephone companies must

not be permitted to obscure the fundamental propositions to which it provides the

exception. First, it justifies mandatory sharing only of facilities or capabilities carried over

from and attributable to the public utility past. Second, wherever mandatory sharing, for

the sake of jump-starting the entry of competitors, would interfere with the more creative

and dynamic investment henceforward in facilities-based competitive entry and innovation

by incumbents and challengers alike, it is the latter that must take primacy. As Justice

Breyer observed in concurring with the U.S. Supreme Court’s decision overturning the

FCC’s 1996 Local Competition Order’s requirement that the ILECs provide competitors

with all network elements to which access is technically feasible, if rivals can share

whatever ILEC facilities they ask for that can feasibly be provided, at rock-bottom prices—

with their mere asking satisfying the conditions for mandatory sharing set forth in the Act—

- 20- A.E. Kahn/T.J. Tardiff

it cannot but have a discouraging effect on their own initiative and innovation and, equally,

on the willingness and ability of the ILECs themselves to undertake large risky investments

in developing and incorporating new technology in their networks. In particular, much of

the investment necessary for ILECs to extend broadband services to more customers and to

provide broadband services with new capabilities entail not simple electronic upgrades to

existing copper lines, but deployment of new ways to incorporate fiber optics and wireless

technologies into their networks.

29. As the foregoing reference to “rock-bottom prices” suggests, the disincentive to innovation

posed by the FCC’s standards for identifying UNEs for mandatory sharing is grossly

accentuated by the costing method it has prescribed for pricing them. This method, the

estimated total-service long-run incremental cost (TELRIC) of a hypothetical most efficient

new entrant, writing as it were on a blank slate, essentially ignores the actual incremental

costs of the incumbent suppliers.30

30. The wide differences produced by the Commission’s prescribed models, consistently lower

than estimates by the incumbent companies of their actual incremental costs, cannot be

attributed to the natural tendency of regulators to underestimate and regulatees to

exaggerate the costs on the basis of which rates are to be set. The Commission has

rationalized its endorsing of the models in part on the basis that it expected the incremental

costs of the incumbent companies to reflect inefficiencies on their part. But that rationale,

automatically assumed to explain the difference, is absurd. Not only is it irrational, in terms

30 “Why should these firms invest in new, often risky technology for delivering advanced, high-speed services if they are to be required to offer any such new facilities to their rivals at cost”—moreover, “not the Company’s

- 21- A.E. Kahn/T.J. Tardiff

of the entire economic case for basing efficient prices on the actual marginal costs of

incumbents; it also ignores the likelihood that an existing network, maximally efficient as

of the time of its installation, will, because of the interdependencies between its various

elements, contain some that could be replaced by more efficient elements with lower

incremental costs only as part of a totally new system. The least-cost expansion path of an

incumbent telephone company will necessarily be constrained by its inherited total

complement of facilities, so that it could take advantage of the putatively lower incremental

cost of an individual element only by taking on the additional cost of redesigning its entire

network. That neither party believes that the blank slate estimates approximate either the

ILECs’ own incremental costs or those that would actually prevail under competition is

demonstrated by the fact that neither of them actually follows the logical implications of its

results, even though it would be the obligation of the former and in the clear interest of the

latter to do so. If commissions that still regulate on a rate-base, rate of return basis believed

those results, or that they reflected inefficiencies on the part of the incumbents, they would

be derelict if they failed either to order the companies to scrap their existing facilities

forthwith and take the lower incremental cost route dictated by those models or disallow a

large portion of their rate base on grounds of imprudence. That they do not do either of

these can only be if they fail to recognize this opportunity, or recognize that the difference

between the estimated blank slate incremental costs of an individual element and those of

the incumbent need not at all reflect inefficiency on the part of the latter; that adopting the

hypothetical lowest cost expansion path for that element alone will be most unlikely to

actual cost,” but “at prices that reflect most efficient technology?” Robert W. Crandall, “The Telecom Act’s Phone-y Deregulation,” Wall Street Journal, January 27, 1999.

- 22- A.E. Kahn/T.J. Tardiff

represent the lowest cost expansion path actually available to even the most efficient

company. And if the companies—most of them subject to price cap regulation—believed

them, they would be derelict in their obligations to stockholders if they did not likewise do

so, abandoning all their present facilities and availing themselves of the assertedly lower

present and future costs of the TELRIC blank slate path.

31. Further, as long as broadband services are subject to regulatory pricing and unbundling

obligations, the possibility remains that an ILEC could upgrade and/or change its network

at considerable risk and, on the ground that competitors would be impaired in their offer of

services using these capabilities, be confronted with an obligation to unbundle those new

capabilities and make them available to CLECs at bare-bones TELRIC prices.

32. This possibility is by no means merely hypothetical. After all, it is extremely unlikely that

Congress had DSL services in mind when it developed the Section 251 requirements. Yet

the FCC did not hesitate to apply those requirements—presumably developed with voice

services in mind—to advanced broadband services when it ordered line-sharing. Further, as

we described earlier, even when it refrained from unbundling packet switching where

copper loops are available, the FCC qualified its action with the wording “at this time.”31

33. In light of the lead that cable modem services enjoy and the FCC’s decision to refrain from

regulating them, competitive parity would call for a corresponding relaxation with respect

to DSL services of the ILECs. The same consideration would argue for freeing them,

31 One of the facts the FCC considered was that because ILECs did not have a large market share in broadband services, a CLEC would have the benefit of similar scale economies in providing packet switching (par. 308). This reasoning leaves open the possibility that if ILECs were “too successful” in competing for DSL, they could ultimately be deemed to have a scale economy advantage that could then possibly be used to justify mandatory unbundling.

- 23- A.E. Kahn/T.J. Tardiff

specifically, from the obligation to share, especially at prices reflecting the FCC’s

hypothetical, ideally efficient firm standard.

34. Consider the anomaly of expecting the incumbent local telephone companies to incur these

costs and handicaps in competition with giants such as AT&T—the largest provider of

cable television and broadband services. If their new offerings lose out to that competition,

they could recover none of the costs in the FCC-dictated charges for their network

elements, because an ideally-efficient firm never fails! Should their new services instead

prevail, they would be required to make those elements available to would-be entrants at

wholesale prices based on the efficient-firm cost standard, with costs of capital typically set

at traditional public utility levels. In its recent supplement on “Innovation in Industry,” The

Economist cites an American study which found, in nice contrast, “that the overall rate of

return for some 17 successful innovations made in the 1970s averaged 56%.”32 What

incumbent telephone company would undertake costly and risky innovations in the face of

such a prospect of grossly asymmetrical treatment of successes and failures?33

35. It may appear anomalous, in view of the already manifest demand of subscribers for high-

speed Internet access and new video services, among others, to point out that the losses

consumers suffer from regulatory policies that have discouraged innovation are not directly

32 “Innovation in Industry,” Supplement to The Economist, February 20, 1999. 33 It is not only in their effect on the incentives of the ILECs to undertake costly and risky investment in modernizing their networks that the FCC’s sharing and network element pricing are likely to prove so harmful. They could also severely impair the ability of the incumbents to finance such ventures, by sharply reducing their internal cash flow: retained earnings are frequently the preferred means of financing such risky large- scale investment projects. See K.A. Froot, D.S. Scharfstein and J.C. Stein, “A Framework for Risk Management,” Harvard Business Review, November-December 1994. S. Fazzari, R.G. Hubbard, B. and Petersen, “Financing Constraints and Corporate Investment,” Brookings Papers on Economic Activity 1, 1988, report that retained earnings constitute more than 70 percent of the source of funds for corporate investment (p.

observable. The essential evil of such policies is that they discourage or delay the

introduction of services that cannot be predicted beforehand. The costs to consumers can

be enormous.34

36. Moreover, competition alone can be relied upon to provide opportunities for CLECs

requiring access to unbundled broadband facilities of the incumbents and to offer

consumers choice among competing Internet service providers (ISPs), if their offerings can

survive the competitive test. If transport facilities are most efficiently utilized through

unbundling arrangements, providers competing with one another will not require regulatory

compulsion to enter into them. Similarly, the competition that will emerge from relying

primarily on markets rather than regulation will also provide customers with choice among

ISPs, because it will be in the competitive interest of access suppliers to provide it. The

more competitive the market is, the more sufficient are the incentives of facilities-based

providers to negotiate such arrangements. In a competitive market, with multiple platforms

available for providing service, if one provider withholds its cooperation from independent

ISPs in the hope of vertically extending its control from transport to content, the ISPs can

work with its rivals, who will thereby gain a competitive advantage. The critical point is

that where, as here, a market is competitive, market forces are sufficient to encourage

participants to reach arrangements that will maximize consumer welfare. It is strongly

preferable that all such arrangements be negotiated on mutually beneficial terms rather than

on terms set by regulators.

147, Table 1) and that on average firms reduce their capital expenditures by more than 36 cents for each $1 reduction in cash flow (p. 167, Table 4).

- 25- A.E. Kahn/T.J. Tardiff

37. These considerations weigh strongly against any requirement that ILECs unbundle facilities

such as access to fiber optics and electronics in remote terminals that require large new

investments. In contrast, the logic of the FCC’s requiring ILECs to make their existing

copper loops available to competitors for access to the high-frequency portion of the

spectrum may seem unexceptionable and not inconsistent with dynamic, innovative

competition: the incumbents enjoy that opportunity merely because of their inherited,

historic control of their copper-wired access networks and there is no immediately apparent

reason to permit them to deny competitors access to those capabilities.

38. The Commission’s ordering of mandatory provision of such access fails, however, to take

into account three critical facts and counter-considerations:

· In the offer of broadband services, the ILECs are not only in intense competition with many other companies offering high-speed access, most importantly to the Internet, via cable, satellite and wireless transmission; they are markedly behind their main competitors, the cable companies. · To compete in this market, the ILECs are indeed making very large risky investments—to the tune of billions of dollars a year—to incorporate DSL capabilities in their lines. The obligation to offer competitive access providers use of the high-frequency portion of those lines—thereby excluding their own use of the lines for that purpose—clearly biases the economics of that decision, because, unlike providers of cable modems, the ILECs would be forced to share potential DSL volumes with CLECs, who in turn would receive access to customers at very attractive prices (because of line sharing). It particularly skews the economics of their competition with the cable companies, which have likewise inherited from their previous monopolies the capability of using their coaxial cable for broadband access, without being subject to any such sharing obligation, and have a much larger portion of the market than the ILECs. · The FCC’s decision in effect assumes that the optimum telephone company network will remain as it is—predominantly copper subscriber loops; but in fact, to compete in this and other markets, the ILECs will have to upgrade their networks

34 Hausman, op. cit., estimated that the annual economic welfare losses associated with the delay of voice messaging were on the order of $1.3 billion.

substantially, particularly by installing a great deal of fiber optics and associated electronics.35 To the extent they do that, it would disable the CLECs’ DSL services now provided over copper loops; so continuation of a general line-sharing obligation in effect requires the incumbents to maintain two networks—or to unbundle the fiber as well—precisely the kind of extremely expensive risky new investment to which the logic of mandatory network element sharing is least applicable and most inhibiting of dynamic competition.

IV. CONCLUSION

39. Whatever the merits of the intention of the Telecommunications Act to open local

telephone markets to competition, extending the unbundling and sharing obligations of the

incumbent telephone companies to broadband transmission of data, including Internet

access, is not conducive to efficient competition for broadband services.

40. Moreover, the underlying rationale that the incumbents enjoy monopolistic control over

facilities necessary for the challengers to compete with them in this market is simply not

correct.

41. On the contrary, extension of those requirements to the ILECs, particularly at the FCC’s

prescribed TELRIC prices, can only severely handicap them in competing with the

incumbent cable companies, who are—properly—subject to no such obligations and now

have a far greater share of that market.

42. The result can only be a severe impediment to the very large risky investments in exploiting

the almost inconceivably large potential benefits of this new technology. Far from being a

logical part of a program to encourage broadband competition—and competitive innovation

in particular—it can only discourage that process.

35 In fact, as we reported earlier, three-quarters of the recent growth in lines for Verizon is accounted for by lines with some fiber.
