INTELLECTUAL PROPERTY A request was made to determine if attendees were aware of intellectual property rights (IPR) associated with TR-29 work. The status of IPR was as follows: • Mixed Raster Content - Xerox may have IPR related to this work and has submitted an updated IPR statement (TR-29/96-11-55 offers this IPR at no charge). • JBIG2 - Xerox may have IPR related to this work with respect to the rendering of JBIG-2 images. LIAISONS ISO/IEC/SC29/WG1/JBIG (Joint Binary Image Group): There has been some progress made on the JBIG-2 working draft. The draft is to be put out shortly and will be made available on the web site to members. In addition, some IPR has surfaced, Xerox has applied for patent rights. The rights are not related to the compression method itself, but there are pending rights related to rendering of JBIG-2 images. There are also plans to make source code available to members and other interested parties. Currently, JBIG-2 is targeted for completion and approval by the year 2000. ISO/IEC/SC29/WG1/JPEG2000 (Joint Photographics Expert Group): TR-29 has decided that a wavelet method will be used for JPEG 2000, based on a coder from the University of Arizona. Work is now proceeding on the architecture which will surround the coder. There is also work ongoing in terms of treating regions of interest in a page in a particular way; the method being used is based on a tiling approach. Xerox and members of the JBIG committee have proposed that the JPEG 2000 committee consider using the Mixed Raster framework as a potential architecture framework. There are two competing architectures related to the architecture itself. There was an interim meeting scheduled in September for St. Petersburg reporting on the results of some experiments. The timetable for this standard is likely to be later than that of JBIG-2. TR-29.4 G. Constantinou (US Department of Defense) reported on results of the TR-29.4 meeting. TR-29.4 is working on extending MIL-STD-188-161-D to support 16 kbit/s operation. Ricoh has worked on the design. G. Constantinou is working on the form of the document. The group is also working on interworking with the new secure phone method (Secure Terminal Equipment [STE]). Interoperability testing regarding STE will take place at Fort Huachuca. The 188-161D changes were submitted to NATO (North Atlantic Treaty Organization) to update STANAG 5000 (NATO Standardization Agreement) over a year ago, but there has been an insufficient number of respondents so far to proceed with approval. COLOR FAX L. McIntyre (Xerox) reviewed results of the SG8 meeting as related to color fax. As noted in the last TR-29 meeting, there has been a change in marker segments (reducing three to one), which results in changes to the T.44 (Mixed Raster Content) document. Since the changes are substantial, it was decided that T.44 should be re- Determined and targeted for final approval in April 1998. The updated T.44 will also contain support for a multi- layer model. In addition, the relevant changes to T.4 and T.30 were also re-Determined. The already published T.4 and T.30 amendments regarding Mixed Raster Content will be declared invalid due to the various changes required. There will be an interim meeting of Question 5/8 in Japan on October 5-8. T.43 (Palletized color) has also undergone delays due to lack of assignment of marker segments by the AFNOR body (Association française de normalisation [French Standardization]). A new registration body was set up in July known as JURA (JPEG Utilities Registration Authority). It is anticipated that JPEG markers will now be assigned in a more timely manner. HF RADIO FAX, PN-4196 There have been some comments received on the re-balloting of PN-4196 (to become TIA-668-A when published). Only Yes votes have been received and the comments appear simple to resolve.

TEST CHARTS AND TEST IMAGES A new T.24 CD (Compact Disk) will be prepared which will take up two CD-ROMs. There is also a table of the percentage of black and white for the images on the disk. V. Cancio (Xerox) expressed concern that some users may incorrectly use the tables to compute the amount of consumables required. Contributions are invited. TIA 465/466 (US STANDARDS FOR T.4 AND T.30 S. Urban (TR-29 Chair, Delta Information Systems) has followed up with TIA regarding the idea to prepare a road map to the ITU documents, in lieu of proceeding with the projects to update TIA-465 and TIA-466 to the latest T.4 and T.30 revisions. S. Urban will prepare a project statement and close the other projects. SG8 CONTRIBUTIONS The following documents were reviewed and approved as proposed US White contributions to be forwarded to SG D (US Study Group D). All of the documents had been previously reviewed in TR-29.1 (see below). TR-29/98-08-29 (H. Silbiger, Lucent, same as TR-29.1/98-08-46R1) to SG8/Q4 TR-29/98-08-30 (G. Griffith, Rockwell, same as TR-29.1/98-08-47R2) to SG8/Q1 TR-29/98-08-31 (D. Duehren, Brooktrout, same as TR-29.1/98-08-48R2) to SG16/Q13 as a Delayed contribution TR-29/98-08-32 (V. Cancio, Xerox, same as TR-29.1/98-08-49R2) to SG8/Q4

OTHER BUSINESS There are proposals underway to change IPR policies for the ITU. It has been suggested that each contribution to the ITU should be accompanied by an IPR statement (similar to the TIA policy). A meeting will be held shortly to discuss the US position to be taken on these matters. There were concerns expressed by some members about this change, since it may be impractical to submit statements for contributions such as those submitted on behalf of an administration. Interested companies are encouraged to participate in the discussions. There was also discussion about the ITU copyright policy related to source code included with recommendations. The ITU does not currently have a copyright policy, other than to assume that the ITU has rights for publication, which does not address the issue of source code associated with recommendations (TR-29/98-08-28R1 from AT&T). The document includes a proposal on the matter of the copyright statement, which is a mark-up of a proposal previously submitted by Germany. The statements which are proposed are that 1) the copyright holder may turn over copyrights to the ITU for the purpose of publishing the copyright material in the Recommendation, or 2) agree to license them on a reasonable and non-discriminatory basis. The US is currently developing its position on this matter. No action was taken in TR-29. There was also discussion about possible future authority of TR-29 to directly approve US contributions. The State Department meetings currently perform this function. It is possible for a group such as TR-29 to act independently of the State Department, by having a separate meeting after the meeting or by circulation of the documents electronically. The ongoing discussion on this matter is being addressed within the State Department. TR-29.1 FACSIMILE AND FILE TRANSFER PROTOCOLS

INTELLECTUAL PROPERTY A request was made to determine if attendees were aware of intellectual property rights (IPR) associated with TR-29.1 work. The status of IPR was as follows (no new statements were made): Internet Fax - D. Duehren (Brooktrout) is aware of Intellectual Property associated with dial forwarding. D. MacTaggart (CyberFax) is aware of potential IPR that may apply for real time fax over the Internet. Fax Security - There is IPR on the security page from France Telecom and on public key management from RSA. SG8 LIAISON REPORT

SG8 Question 1 J. Rafferty (Human Comm.) reported on the Question 1/8 meeting (see CSR-T Vol. 9.6). The amendments which had been proposed for T.30 were approved, with the exception of support for Internet fax modes which were Deter-

October 1998 Vol. 9.7 Copyright © CSR 1998 3 COMMUNICATIONS STANDARDS REVIEW – TELECOMMUNICATIONS mined. There were also several other features which were Determined including Internet addressing (support for email and URL [Uniform Resource Locator] addresses), and higher resolutions (600 x 600 and 1200 x 1200). Support for a voice bit using G.726 compression has also been Determined; the actual voice data can be transferred using basic transfer mode or binary file transfer. Annex X on extended negotiations was Determined, although reservations were expressed by two delegations. The Phase B method of BFT (Binary File Transfer) negotiations has also been Deter- mined. The private use document from the US was well received, but is still for further study. The V.21 duplex method was Determined. SG8 Question 2 (Facsimile Test Charts and Test Images) S. Urban (Delta Information Systems) reported that a new amendment to T.24 has been approved, to add 28 more images, including more color images. SG8 Question 3 (Cooperative Document Handling) J. Rafferty reported that Amendment 1 to T.434 (Binary File Transfer) which adds support for new store-and-forward and archiving attributes was approved. In addition, a new draft amendment was prepared and Determined. The new amendment will include support for MIME (Multipurpose Internet Mail Extension) media types as an additional identification method. Q3/8 will work on updating the ASN.1 syntax and references within T.434 for conformance with the updated X.680 series of ASN.1 recommendations. SG8 Question 4 H. Silbiger (Lucent) reported on Q4/8. T.38 was approved. It was also decided that both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) need to be supported in implementations. The new Annex B was Determined, in a form similar to that submitted by the United States. A liaison was received from SG16 which responded to the draft liaison previously prepared by the US, but the timing of the Q13/16 rapporteur meeting prevented a reply to the latest version sent from SG8. There has since been some informal communication from SG16. T.37 was approved; it references four RFCs from the IETF, per the rules of the new A.005 recommendation. IETF INTERNET FAX LIAISON J. Rafferty reported on the IETF Internet Fax working group activities. The group has not met since the last TR-29 meeting, but has been actively discussing the confirmation methods required for the full mode of Internet fax (supports the transfer of the image with capabilities and confirmation data). There is a rough consensus that DSN (Delivery Status Notification) should be the delivery confirmation method; a processing confirmation is also needed for some situations. There is also a need to work on capabilities exchange; this work is not yet stable. The working group will meet again in Chicago during the last week of August. INTERNET PRINTING PROTOCOL (IPP) LIAISON It was noted that the documents for this work can be found on the IPP web site (http://www.pwg.org/ipp). The model involves use of HTTP (HyperText Transport Protocol) and defines different printer description languages using MIME media types. PN-3365, BINARY FILE TRANSFER COMPATIBILITY It was agreed that this project should be closed. PN-3675, EXTENDED NEGOTIATIONS TR-29.1/98-08-40 (J. Rafferty) covers the agreed revisions to extended negotiations documents as reviewed within Q1/8. The Draft Annex X was Determined; this document includes a small set of revisions to the Determined documents. TR-29.1 discussed how to proceed with ENP (Extended Negotiation Procedure). It was noted that the Private use document was generally well received at SG8 and could be re-submitted later for potential Determination. It was felt that it is worth pursuing the Draft Annex X and Private Use as US interim standards. It was reported that SG8 has requested a new range of V.8 code points for facsimile purposes from SG16. In the process of researching this, G. Griffith (Rockwell) found that TIA has been allocated a range of codepoints. It is suggested that a US version of Annex X could request use of a TIA codepoint in order to enable V.34 fax operations using ENP. PN-3799, I NTERNET FAX The focus at this meeting was on reviewing potential amendments to the recently approved T.37 and T.38 recommendations.

D. Duehren (TR-29.1 Chair) introduced the several documents related to T.38. TR-29.1/98-08-33 (D. Duehren, Brooktrout) is the current draft of Annex B (Call Establishment Procedures) of draft Rec. T.38 Annex B was held for further study in SG8 since it is based on the use of H.323 which requires coordination with Q13/16. It is proposed to Determine Annex B in April, 1999. TR-29.1/98-08-34 (H. Silbiger, as Q4/8 Rapporteur on behalf of Lucent) is an updated version of the Liaison Statement from Q4/8 to Q13/16, which was prepared by Q13/16. It also has a copy of some informal correspondence between T.38 editor D. Duehren and Rapporteur D. Skran. TR-29.1/98-08-35 (D. Skran, Ascend) is the current draft of H.323 Annex D (Real-time facsimile over H.323) as submitted by the editor. TR-29.1/98-08-36 (D. Duehren, Brooktrout) identifies some open issues related to T.38. It notes a typo to the ASN.1 in Annex A to T.38 and notes a potential issue related to the use of the TCP transport. The TCP issue is due to the absence of a start of message marker in the ASN.1 when represented as Packed Encoding Rules, whereas the text states that such a marker is present. It was noted that this should not cause a problem so long as the TCP data stream is not corrupted. It was suggested that the simplest way to resolve the issue is to delete the text in order to maintain consistency. D. Duehren will draft a proposal. TR-29.1/98-08-37 (D. Duehren, Brooktrout) reviews open issues on T.38 Annex B and H.323 Annex D. T.38 Annex B issues: • Should RAS (registration, authentication and security) be optional? • What effect will firewalls have? Does RAS do the dynamic port assignment? • How should UDP flow control be implemented, without using H.245 flow control? • Is there a better alternative to UDP and TCP as the default data protocol? • Review the correctness of ASN.1. Verification? • Text is needed for adding the Facility Message into section 3.5 of Annex B, Mandatory Call Setup Messages. • Are we certain how private extensions, identification may be accomplished in the combination of T.38 Annex B and fast Call Setup? H.323 Annex D issues: • Voice support only in T.38 Annex B is not a valid device, yet it is in Annex D. • Promising terminology regarding max bit rate is not present in the latest revisions of the text. There was ongoing discussion on the TCP vs. UDP issue, with questions on how to enhance the UDP method to address issues of sharing the network. TR-29.1/98-8-34 discusses how flow control might be added for UDP using maxBitRate. It was noted that there is an H.323 Implementor’s Guide available on the ITU Web site. The Annex D of H.323 was up for approval in September (It was Decided at the SG16 meeting). TR-29.1/98-08-44 (H. Silbiger, Lucent) covers using V.34 modems with V.38. There was discussion on various aspects. One issue is to handle the case of keeping data rates synchronized so that the two modems will not run into timeout problems due to running out of data. There was discussion on whether there is a need to do an INFOh exchange. A related paper, TR-29.1/98-08-45 (I. McCallum, Dialogic), maps out V.34 exchanges to a T.38 exchange. The group went through the elements of the chart and considered which elements might cause difficulties if they are negotiated differently on the two sides which are using V.34 modems. One of the issues was on what would cause an INFOh signal to be sent again; if you time out, you go back to a starting point before the INFOh is sent. Another issue is to match the timings in terms of the length of TRN training signals that are used. It was suggested that the target should be to prepare a white contribution for SG D in two weeks and then prepare a delayed contribution in October which fills in more of the details. It was decided to set up ad hoc groups for the following topics: • V.34 support in T.38 • Draft Contribution for SG16 via SG D, commenting on any issues related to H.323 Annex D Two papers were introduced on the topic of store and forward Internet fax. TR-29.1/98-08-41 (L. Masinter, Xerox and D. Wing, Cisco) is the latest draft of ietf-fax-eifax-03.txt (Extended facsimile using Internet mail). It is a draft which represents an evolving consensus within the IETF on the requirements and technical details from the full or extended mode of Internet Fax. TR-29.1/98-08-42 (D. Wing, Cisco) is the latest version of the draft-ietf-fax- reporting-extensions-01.txt. This document has proposed extensions to the DSN (Delivery Status Notification) and MDN (Message Disposition Notification) message fields to enable reporting on matters such as offramp delivery to a

G3 fax device and some additional extensions. This is a relatively new draft, so it does not yet represent a consensus opinion of the IETF Internet fax working group. There was a discussion on the implications of the papers with respect to the needs for T.37 full mode. J. Rafferty noted that there had been a communication from the ITU back to the IETF which reviewed full mode requirements, the cases for full mode recipients and included requests for study of certain items. There has been related work done in the IETF discussion lists on these issues. It was agreed that an ad hoc should be formed to review two issues: 1. Preparation of a draft T.37 amendment in support of full mode, which will reference IETF work in progress 2. Review of T.30 to determine which parts are relevant for Internet fax capabilities identification. A preliminary review of the documents from the ad hoc groups was conducted. TR-29.1/98-08-48 (D. Duehren, Brooktrout) is a proposed set of revisions to Annex D of H.323. The main changes were to correct: • References to T.38 Annex B terminals with voice • DTMF (Dual Tone Multi Frequency) tones may need to be supported for inbound routing, ideally without requiring full DTMF support. • Some additional text is needed on flow control. It was felt that some additional comments are needed in the introduction. Later in the meeting an updated version, TR-29.1/98-08-48R1 (D. Duehren, Brooktrout) was reviewed and supported by TR-29.1. TR-29.1/98-08-46 (H. Silbiger, Xerox) is a proposed draft amendment to T.38 in order to support V.34 operations. Changes are proposed to the main body to add support for various V.8 and V.34 signal components within T.38. Later in the meeting, the updated version TR-29.1/98-08-46R1 was reviewed. I. McCallum (Dialogic) noted that the T.30 call indicator (V.8 CI signal) needs to be moved down to the data section of the ASN.1; this change needs to be reflected in the table and in the ASN.1. The document with the additional edit was supported by TR-29.1 as a proposed white contribution to be submitted via SG D. TR-29.1/98-08-49R2 (V. Cancio, Xerox) is a proposed amendment to T.37 for full mode. It includes several mark-ups to the T.37 text as related to confirmation of receipt and capabilities identification. PN-3364, ENHANCED BINARY FILE TRANSFER There were no contributions received. The Phase B method of BFT negotiations was Determined at the June SG8 meeting and will be included in a white contribution to be prepared by the editor of T.30. No further work by TR- 29.1 is needed at this time. PN-3826, BINARY FILE TRANSFER TR-29.1 discussed plans for T.434 updates (PN-3826) as follows. TR-29.1 will continue to move forward on TIA- 614-A (BFT), but include a new annex which has the latest (approved in June 1998) version of the ASN.1, as an addition to the version 2 material. J. Rafferty is the editor of T.434 Amendment 2 within the ITU. There is a need to work on bringing the use of ASN.1 within T.434 up to date as part of the planned enhancements for the next protocol version which was Determined at the June SG8 meeting. FAX PROTOCOL TR-29.1/98-08-43 (K. Chu, Rockwell) discusses interoperability of V.8/V.8bis capable and Group 3 facsimile modems. The group agreed that the following scenario presents a problem. There are no provisions made on how to negotiate the required modulation mode from the V.8 Modulation Category octets for modems which support V.8 or V.8bis and want to use a modulation other than V.34. In particular, for non-V.34 fax operations, the desired modulation is V.21, rather than being a rate such as V.29 or V.17. TR-29.1 felt that the concept is a good idea and could be handled as a note. The text of the note needs to be prepared before this can be supported as US position. There is also a need to specify where the note should be added (i.e., in T.30 Annex F [polling] and/or V.8). TR-29.1/98-08-47R2 (G. Griffith, Rockwell) is the second revision of a proposed contribution for a reduced V.21 preamble The majority of savings anticipated from the V.21 duplex method that has been proposed by the United Kingdom (D-78) can be obtained in the normal V.21 half duplex mode by reducing the number of flags in the preamble to three. The original paper (TR-29.1/98-08-47) suggested that the shortened preamble could consist of an 180 ms EPT plus three flags. It was agreed during discussion that it would still be necessary to maintain the current preamble for the initial DIS frame grouping in order to maintain compatibility. TR-29.1 thought the concept was a

6 Vol. 9.7 Copyright © CSR 1998 October 1998 COMMUNICATIONS STANDARDS REVIEW – TELECOMMUNICATIONS good idea, but offered some minor revisions. Later in the meeting, an updated version (TR-29.1/98-08-47R1) was reviewed. The group wanted further text added, noting that the reduced preamble would only be used as a result of a DIS/DCS bit exchange and more clarification on the time savings, resulting in the second revision. J. Rafferty (Human Comm.) presented two papers which resulted from the June SG8 meeting, defining new proposed enhancements to T.4 and T.30. TR-29.1/98-08-38 (T. Maeda, Canon) contains the amendments to T.30 for Internet related features. The amendments resulted from a combination of ideas submitted in three contributions. The main feature is to support Internet addresses, notably email and URL addresses. The document was Determined. TR-29.1/98-08-39 (B. Revillet, France Telecom) provides amendments to T.4 and T.30 which add support for new features including higher resolutions (600 x 600, 1200 x 1200) and a bit for voice transfers that support the G.726 voice coding. The voice transfers can be accomplished either as a pure data stream without attributes via Basic Transfer Mode or by using T.434 binary file transfer. TR-29.2 FACSIMILE DIGITAL INTERFACES

LIAISON REPORTS MFPA: C. Douglas has been appointed the new director of MFPA (Multi-Functional Peripheral Association). V. Cancio (Xerox, TR-29.2 chair) has been in correspondence with MFPA about IS-650 (Multifunction peripheral interface standard), checking to see if they will want to proceed with a project to update it. ITU-T Q1 Meeting: J. Rafferty reported on the Q1 meeting. A proposal was made to revive the CFP (Computer Fax Protocol) proposal from Wordcraft as a potential standard interface for multi-function peripheral devices. TR-30.2: Microsoft has submitted a proposal on diagnostic messages for modems. It has been proposed that this be submitted as a US contribution to SG16. There is also interest in starting a project on DSL (Digital Subscriber Line) interfaces. In the ITU, the work on DTE/DCE interfaces is being done in Question 7 of SG16. IEEE: IEEE 1284.3 was mailed out for ballot. This is the proposal for daisy chaining of IEEE 1284 interfaces (parallel interfaces). PWG (Printer Work Group): This group is working on IEEE 1394 (ex- Firewire). The packet protocol for this specification is different than the one for IEEE 1284.3. The prospects are that the packet protocols for USB (Universal Serial Bus), IEEE 1394, and IEEE 1284.3 will all be different. ECTF (Enterprise Computer Telephony Forum): J. Rafferty reported on this work. The S.100R2 media resource API (Application Programming Interface) is almost ready for balloting. It contains fax resource APIs. Salutation Consortium: This group has released its port of entry software, which permits existing software to interface to Salutation products. J. Rafferty notified the consortium concerning the progress of related work in the ITU including extended negotiations, the Phase B method of BFT (Binary File Transfer) Negotiations and Private Use. G5 Messaging: Some members discussed the status of this work. The current specification is available on http://www.Group5Forum.org SERVICE CLASS 1, PN-3626 This project takes the latest revisions to ITU-T T.31 (Fax Class 1) and incorporates them into TIA-578 (Fax Class 1) to create the B revision. TIA-578-B was approved via industry ballot, subject to resolution of comments received from K. Krechmer (ACTION Consulting). The comments note the need to change the references from V.25ter to reference the new V.251 recommendation. The V.250 series (V.250-253) replace the V.25ter specification. The editor, J. Dahmen (Lanier), needs to do some further investigation on bringing the references up to date, as part of the process of resolving the ballot comments. SERVICE CLASS 2, PN-3625 PN-3625 has been published as TIA/EIA-592-A, Asynchronous Facsimile DCE Control Standard - Service Class 2. This project will be closed.

MULTI-FUNCTION INTERFACE, PN-3756 This project was targeted to provide improvements to interim standard IS-650. It is not certain whether there will be any further contributions, due to the uncertain status of MFPA participation. Therefore, the project will be closed. CLASS X, PN-3130 There is currently no editor for this work. The current approach is to develop an interim standard supporting extensions to Class 1 to reduce critical timing problems. OTHER BUSINESS J. Rafferty (Human Comm.) provided a liaison regarding a company proposal made at the Fax Directions conference. XML (Extended Markup Language) is a standard markup language that has been approved in the W3C (World Wide Web Consortium). At the recent Fax Directions, V-Systems proposed a set of XML Document Type Definitions (XML-F) that the fax industry consider using in fax transactions between clients and servers. Further information is available at http://www.vsi.com/xml-f. James Rafferty, Human Communications

TR-41 REORGANIZATION A special session was held to brainstorm ideas for a new TR-41 model to address the issues of new technologies, standards globalization, and declining participation in some sub-committees. There was high interest in this session (over 40 people). Among the ideas floated were “bifurcation” (a technical committee and a regulations committee), “trifurcation” (splitting off TR-41.8 in addition to the technical and regulatory committees), combining some of the technical work (e.g., TR-41.1 and TR-41.10 - closer liaison between TR-41.1 and TR-41.3); combining some work with other standard groups (T1, ETSI). All ideas were recorded; the TR-41 chair asked for a volunteer to head up an ad hoc group to review these and come up with a recommendation (no one at this time) as well as volunteers for this group (about 12 volunteers). A teleconference was planned, then postponed to late October, to define a proposed model for TR-41 discussion in November. TR-41.1 MULTI-LINE TELECOM SYSTEMS

T1E1 LIAISON Reporter’s note: No liaison from T1E1 attended; this information is from alternate sources. T1.401 (Interface Between Carriers and Customer Installations - Analog Voicegrade Switched Access Lines Using Loop-Start and Ground-Start Signaling) is being revised and is expected to be ready for letter ballot during 1998. Issues discussed at the latest T1E1.1 meeting include stutter dial tone and unintended line ringing, possibly due to ALIT (Automatic Line Insulation Tests) signals. T1.401.03 (Calling Number Delivery, Calling Name Delivery or Visual Message Waiting Indicator Features Standard) is now published and available from ANSI. This standard is one of a family of standards related to Standard T1.401. Other published members of this family are T1.401.01 (Line-Side Answer Supervision Feature) and T1.401.02 (Distinctive Alerting Features). Work continues on the Calling Identity Delivery on Call Waiting Interface standard (to become T1.401.04). Work progresses on the Network-Implemented Coin-Operated Pay Phone Interface Standard. T1.414 (E-911 PSAP [Public Safety Answering Point] Interface Standard) is now published and available from ANSI. This standard describes the interface between the network and the PSAP; T1.411 describes the interface between the network and customer equipment. TIA-464-B, R EQUIREMENTS FOR PRIVATE BRANCH EXCHANGE (PBX) SWITCHING EQUIPMENT TIA-464-B is due for reaffirmation in the year 2001. A complete revision would entail review of each requirement for verification and current relevance. Furthermore, the current electronic form of the document will require re- formatting. There is concern about both the availability and company support for this substantial editing work. Nevertheless, the document will require updating in several respects; among them: alignment with updated T1 and FCC requirements, simplified loss plan, adoption of TIA-579 level specifications, and orientation to Internet connectivity. Several alternatives were considered, such as publishing an interim addendum with current agreed-on changes as given in the living list (TR-41.1/98-08-019, R. Frank, Siemens), and publishing an errata sheet (for typos and other editorial inconsistencies). It was finally agreed that work should be directed towards the re-issue and update of the document, starting at the next meeting, and structured as follows: • A core group was appointed to review the document section by section to identify those sections that require revision, as well as those new sections, if any, to be added. The core group will meet separately at the next TR- 41 meeting. It includes R. Frank (Siemens), T. Tung (Siemens), P. Weismantel (NEC), and J. Schick (Nortel). • For each revised or new section, subject matter experts will be identified for work on that section. • Requirements addressing mature technology matters (e.g., ground-start operation, DTMF [Dual Tone Multi Frequency] signaling, analog transmission requirements) will not be revised unless specifically requested to do so via contribution. It is believed - and will be verified - that this activity is within the scope of PN-3673, update to TIA-464.

PN-4157, PBX LINE-SIDE INTERFACE REQUIREMENTS Due to time constraints, no contributions were provided at this meeting. It had been hoped that results from the NIUF (North American ISDN Users Forum) survey of BRI (Basic Rate Interface) terminal manufacturers on the issue of terminal interface characteristics could be incorporated into the draft document. However, the response to the survey was so low that there is no real sense of direction from the terminal manufacturers. It appears from the survey that terminal manufacturers do not consider PBX interfaces a high priority. No additional input from NIUF is expected. For the next meeting, P. Weismantel (NEC) agreed to consolidate contributions to date and fill in the services to be provided. Included will be some voice services in support of BRI terminals. The initial goal of this work, however, is to have a common interface to access ISDN BRI B-channels for video transmission and internet access. QSIG INTEROPERABILITY

QSIG is internationally termed Private Signaling System No. 1 (PSS 1). For additional information on QSIG see http://www.qsig.ie/. The project authorization request for a TSB (TR-41.1/98-08-020, R. Frank, Siemens) was voted to be sent to TR-41 for approval and TIA processing. The scope and purpose of the project had been discussed and agreed on at a teleconference on July 20. One issue concerned terminology for the project title and description. TR-41.1 chose “interoperability” which relates more to the functions, whereas “interworking” could connote protocols, which is outside the scope of the TSB. The goal of the TSB is functional testing. An outline of the TSB will be generated by P. Melton (Cortelco), and W. Soler (Lucent) for the November meeting, including most of the QSIG features that are normally implemented by manufacturers. TR-41.1/98-08-022 is correspondence from R. Ceruti (CSELT, Italy), noting that CSELT is doing QSIG interoperability testing in their testing facility but that their concern is that products are “future proof;” e.g., capable of operating with any future products adhering to the same standards. R. Ceruti indicated interest in future exchange with TR-41.1 on QSIG interoperability testing issues. J. Schick, as TR-41.1 chair, will follow up with R. Ceruti to explore the possibility of further discussion on these issues. TR-41.1.1, MULTI-LINE TELECOM SYSTEMS - TRANSMISSION For this meeting, MLTS Transmission Support, previously assigned to this Working Group, TR-41.1.1, was covered as part of the TR-41.1 meeting. Due to changes in work scope as well as member participation, it is anticipated that this working group will be discontinued. PRIVATE NETWORK TRANSMISSION PLANNING GUIDE At the previous meeting, it was planned that the Private Network Transmission Planning Guide, based on the ETSI Transmission Planning Guide (ETSI Guide EG 201 050), would be finalized for letter ballot in time for balloting to take place prior to this meeting. However, the preparation of the letter ballot draft required more extensive editing than envisioned; in addition, the process uncovered the need for certain technical modifications for North American telecommunications environment compatibility. Thus, the revised main body (without annexes) of the document was re-submitted (TR-41.1/98-08-023, Draft TSB-32, T. Tung, Siemens, K. Cheung, Nortel, and J. Schick, Nortel) for review and approval. To assist in the review, major changes, including all technical modifications, were listed in a separate handout (TR-41.1/98-08-024, J. Schick, Nortel). The revised draft was reviewed and approved for forwarding to TR-41 and to TIA for letter ballot, with corrections to be made as a result of the review at this meeting. Reporter’s note: Prior to completion, the document was reviewed with members of ETSI STQ at a separate meeting; comments (all editorial) from this review are also to be incorporated in the letter ballot draft. As previously reported, the document will become a global transmission planning guide, issued by ETSI as the second version of their EG 201 050, and by TIA as the revision/ update of TSB-32. TSB-32 COMPANION APPLICATION DOCUMENT As previously agreed, the analyses of North American intra-net and of inter-network connection scenarios were merged into a single document (TR-41.1/98-08-021, K. Cheung, Nortel) to become a companion document to

TSB-32 (DPBX Loss Plan Application Guide). The examples in TSB-32 show the practical application of the transmission planning principles described in TSB-32 and the use of the ETSI E-model in analyzing, and possibly optimizing, the voice transmission performance of typical end-to-end connection scenarios in North America. The merged document includes a number of changes from the source documents, including the harmonization of the 0 dBr point to be at a digital point and analyses in each example of the performance from both the side A and side B (connection end-points) point of view. Also included in this issue are a Table of Contents, References, and a list of abbreviations. The document was voted to be forwarding to TR-41 and to TIA for letter ballot in conjunction with the TSB-32 letter ballot. TIA administration concurred in the official designation of the document as a “companion document.” PROPOSALS AND PLANS FOR FUTURE JOINT PROJECTS No new transmission work is currently proposed. J. Schick, T. Tung, and R. Britt will be attending the next ETSI TIPHON (Telecommunications and Internet Protocol Harmonization Over Networks) meeting to determine any possible joint VoIP (Voice over IP) work program with ETSI, either within TIPHON or in conjunction with ETSI STQ. (Refer to the TR-41.1 report in CSR-T 9.5 for an overview of STQ and TIPHON activities. Also see the TIPHON August meeting report in this issue.) TR-41.1.9, MULTI-LINE TELECOM SYSTEMS SUPPORT OF ENHANCED 911 SERVICE

INTEGRATED SERVICES DIGITAL NETWORK (ISDN) SOLUTIONS FOR E911 SIGNALING. TR-41.1.9/98-08-05 (D. Greene, Rockwell) is the updated T1S1.1 working document on a proposed enhancement to standard T1.607 (DSS1 Layer 3 Signaling Specifications) to add support for emergency service calls at the user-to-network interface. Specifically, the procedures described address the delivery of location information to the network side of the ISDN access. The enhancement expands the table of message content on set-up and provides for a generic information element. The new annex on emergency service signaling has been expanded with respect to the functional description of emergency calling, including a functional model. At the next meeting, TR-41.1.9 will start considering the process for incorporating this information into the TIA E911 standard (TIA-689). John Schick, Nortel

TR-41.2, CONFORMITY ASSESSMENT

EUROPEAN UNION - US MRA The EU-US MRA was signed May 18, 1998. Editor’s note: the agreement may be found at http://www.itaiep.doc.gov/mra/mra.htm. There is great interest on the part of Europe to begin the implementation efforts sometime in November. The US Government will schedule an information exchange meeting during mid- November. EUROPEAN UNION - CANADA MRA The EU-Canada MRA was signed May 14, 1998. Canada is also planning to begin in mid November. Industry Canada has suggested that the US and Canada may wish to hold a joint workshop with the EU. In addition, Industry Canada will hold its own internal informational briefings. APEC STATUS REPORT The APEC (Asia Pacific Economic Cooperation forum) Mutual Recognition Arrangement, like the MRAs with Europe, is a two phase arrangement; it includes a mutual recognition of test results phase followed by a mutual recognition of certification competency. This arrangement accommodates the APEC members who are ready to sign on, when they are ready to sign on, and is best understood as a series of bilateral arrangements between the economies who are ready to participate. The framework for the arrangement calls for a long term goal of suppliers declaration of conformity between the parties. It is likely that the arrangement will require legislative and regulatory changes within the member economies. The US process for formal designation of CABs (Conformity Assessment Bodies) for this and other MRAs will be included in an FCC NPRM to be released in mid-May, 1998. At this time,

sixteen APEC economies have signed this agreement. C. Berestecky (Lucent, Chair TR-41) will lead the implementation discussion during the next round of APEC MRA talks in September 1998. S. Crosby (Lucent) will attend the APEC SCSC (State Council Steering Committee) meeting in Malaysia and participate in a round table discussion on regulatory reform. CITEL (COMISION INTERNAMERICANA DE TELECOMUNICACIONES) ACTIVITIES Activities within CITEL, InterAmerican Telecommunications Commission part of the Organization of American States, are occurring in the form of workshops and an interest by the economies to develop an arrangement similar to APEC. H. Mar (Industry Canada) reported at the last meeting that one of the first items on the CITEL agenda will be Market Access and Technical Barriers to Trade. Also the Free Trade Agreement of the Americas will be useful to the CITEL economies. S. Crosby (Lucent) attended the Brazil-US Business Council Meeting. Brazilian industry representatives attending the Standards Task Force meeting expressed a desire to: • Promote the simplification and harmonization of standards, technical requirements and regulatory procedures in the FTAA negotiations, including the promotion of applicable international and regional standards; • Negotiate an MRA for ITE (Information Technology Equipment), telecom equipment and consumer products; • Acceptance of the “once tested, accepted everywhere” principle for the acceptance of test data from an accredited third party laboratory or manufacturer’s lab; • Pursue suppliers declaration of conformity concept; • Ensure that standards and conformity assessment are relevant items in FTAA (Free Trade Area of the Americas) negotiations or any bilateral initiatives toward global harmonization; • Harmonization of requirements for product marking; • Ensure that standards are adopted on a voluntary basis and established by recognized official national standards organizations; • Ensure that all technical regulations should be based on voluntary standards, where standards are necessary. OSHA RELATED ACTIVITIES A joint TIA/ITI visit to OSHA was planned for June, 1998. Due to schedule conflicts, TIA and ITI met separately with OSHA. The focus of the TIA meeting was to establish an ongoing relationship with OSHA to discuss possible areas of future regulatory relief for the telecom and IT sectors. The focus of the ITI meeting was to express the ITE industry’s preference to adapt the current US regulatory framework for product safety to the EU regulatory model. The first joint meeting will be scheduled for September 1998. TIA & TR-41 MEETINGS WITH THE FCC The TIA and representatives from TR-41 continue to meet with the FCC to discuss further streamlining of Part 68 and privatization of the product approval process. Future meetings between the TIA and the FCC are planned and will include discussions on the possible use of suppliers declaration of conformity. TR-41.2/98-08-012 is the partial compilation of comments to NPRM (Office of Engineering and Technology) GEN. Doc. 98-68. TR-41.2/98-08-013 is the R. Breden’s (TIA) summary of TR2TF meeting to develop 98-68 replies. Technical editor’s note: See http://www.fcc.gov/oet/dockets/gen98-68/ for the text of this docket. OTHER HIGHLIGHTS R. Breden reported on TIA’s plans to participate in the development of building standards guidelines as they relate to telecommunications standards. The organization leading the development of these guidelines is the National Institute for Building Standards (NIBS). For more information, contact R. Breden (TIA) and/or the NIBS web site: http://www.nibs.org/. An informal ad hoc group met immediately after the Norfolk meeting to discuss possible future TR-41.2 initiatives in support of the upcoming MRAs and other TR-41.2 conformity assessment objectives. Several ad hoc groups were formed to address these objectives. Any output will be circulated to TR-41.2 members prior to the next meeting: • Terminology Ad-Hoc Group (TAG): G. Panger (BABT) - leader, A. Bal (CSA), S. Crosby (Lucent), T. Tung (Siemens). G. Panger (BABT) presented TR-41.2/98-08-014 (TIA TR-41.2 Conformity Assessment Dictionary/Glossary) to the TAG.

• MRA Implementation Guide Group (MIGG): S. Crosby (Lucent) - leader, P. Adornato (Nortel), H. Mar (Industry Canada), G. Slingerland (Mitel), G. Panger (BABT), T. Tung (Siemens), A. Wride (CCL). The MIGG will meet on September 25, 1995 at 1:00 PM to discuss MRA implementation issues.

TR-41.3, ANALOG AND DIGITAL WIRELINE TELEPHONES The TR-41.3 report was not available.

TR-41.5, MULTIMEDIA BUILDING DISTRIBUTION SYSTEMS TR-41.5 worked on the definition of minimum application, feature and operational requirements of a Residential Gateway (RG). RESIDENTIAL GATEWAY TR-41.5/98-08-021© (R. Cochran, GTE) is Draft 6 of PN-3771, the Residential Gateway Standard. It reflects the changes made in the May TR-41.5 meeting. TR-41.5/98-08-022, Residential Gateways: Business and Technical Issues (W. Caswell, IBM) provides a very interesting broad survey of the RG environment. Included are overviews of the RG product and market approach of utility companies, telco and cable HFC access, IBM, Lucent, WebTV, start-up Utel, GI’s Next level Communications, and start-up Global Converging Technologies. Web addresses: IBM http://www.pc.ibm.com/us/accessories/homedirector Lucent http://www.bell-labs.com/org/11356.htm WebTV http://www.webtv.net Next level Communications http://www.nlvl.com/press/productnews/prod_060397b.html Global Converging Technologies http://www.globalconv.com TR-41.5/98-08-023, a presentation on Residential Gateways in GTE (M. Baker, GTE), provides an informative update on GTE’s latest thinking and directions involving Residential Gateways. GTE supports a centralized RG approach and has identified ADSL and VDSL as access technologies that can support an RG system. The significant achievement of this TR-41.5 meeting was the bold step taken by TR-41.5 in selecting PCI technology for the internal digital interface (a.k.a. the “bus”) of the RG. While this decision was seen as the linchpin to further progress by TR-41.5, it was also recognized that other emerging technical and business issues are yet to be resolved and likely a number of them will be difficult to accomplish in a timely manner. Accordingly, in light of the perceived industry need for information and direction on the topic, TR-41.5 decided to publish their current RG work as a “TSB” (TIA Telecommunications Systems Bulletin). TR-41.5 plans to be in a position to vote the proposed TSB out of committee at the November meeting in Palm Springs. Towards that end, there will be an interim editing session (Raleigh, NC, October 27-28, 1998) to resolve and finalize format and content details. ISO/IEC JTC1 SC25WG1 addresses the Residential Gateway issue on the international standards front. TR-41.5’s interaction with them has resulted in the incorporation of TR-41.5’s concerns into their final committee draft entitled “Homegate: A Residential Gateway Model for HES” (Home Electronic System). Although this draft is now moving forward for balloting at the SC25 national body level, further liaison with SC25WG1 is planned. Detailed information is available at http://www.labs.bt.com/profsoc/sc25wg1. VESA HOME NETWORK LIAISON A liaison report on the VESA Home Network Committee’s June and August meetings provided an update on related activities. VESA is still considering approaches and technologies for their address and control needs. Recent presentations to the VHNW Committee on this matter included “HAVi” by the HAVi Consortium, “JINI” by Sun, “Internet Home Access” by Echelon, “Home Wide Web” by Samsung, and “Generic CAL.” • “HAVi” (Home Audio/Video Interoperability architecture) can be viewed as middleware that provides a set of APIs for consumer electronics interoperability. HAVi is NOT a distributed OS (operating system) but provides a

lightweight platform for distributed applications delivery. The intent is to exploit the capabilities of IEEE 1394 technology …especially high bandwidth, low cost, flexible interconnection. For additional details, see http://www.sony.co.jp/HAVi/. • “JINI” by Sun is a new technology that expands the power and applicability of JAVA to enable networking of a wide variety of hardware and software. It is 100% JAVA and provides a “toolbox” for discovery, lookup, security and control. However, none of the applications have yet been developed for a home network application. For additional details on JINI, see http://java.sun.com/products/jini/. • “Internet Home Access” by Echelon is a control system based on LONWORKS that addresses home automation issues. A recent alliance between Echelon and Cisco provides a means to establish internet connectivity and extend the possibilities of their system for access and control. For additional details on this approach, see the demo at http://www.echelon.com/demo that features LONWORKS certified products to turn on & dim lights, raise shades, adjust thermostats, etc. • “Home Wide Web” by Samsung is built around the premise that a browser approach and IP is the current and most promising paradigm for future home networking issues. In this model, all display devices feature a GUI (Graphical User Interface) that is rendered via html and manipulated in browser fashion. A website is being developed to provide additional info on Samsung’s “Home Wide Web,” but is not available as of this writing (check http://HomeWideWeb.net/ for status). • “Generic CAL“ has evolved from the CEBus venture and provides a means for command and control over various media. The technology is widely used and viewed as being consistent with pc, home automation, consumer electronics, and set-top box industry’s requirements and efforts. Technical Editor’s note: Previous EIA efforts included the creation of the EIA-600 standard for home automation. EIA-600 was a comprehensive network protocol that included a command and control language called CAL, the Common Application Language. It has since been rescinded. The EIA is now developing Generic CAL as an industry standard, designated EIA-721, for resource management and device control on the various networks found in the home. These transport networks include everything from high speed IEEE 1394 clusters to Ethernet and power line networks. An early adopter of Generic CAL is the EIA R4.1 Committee. This consumer electronics committee is specifying a standard interface for Advanced Television (ATV), including High Definition Television (HDTV). Examples of data formats to be transmitted include AC3 audio and MPEG video. The R4.1 Committee is investigating linking Generic CAL with the protocol elements used for the Internet (the TCP/IP or UDP/IP stack). The combination of Generic CAL with the Internet protocols affords numerous possibilities for services and applications, including home monitoring and control via the Internet. Richard Cochran, GTE

TR-41.6, WIRELESS USER PREMISES EQUIPMENT (WUPE) The attendance at the TR-41.6 meetings was low again at the opening plenary. TR-41.6.1, PWT (PERSONAL WIRELESS TELECOMMUNICATIONS) TIA-662 SERIES The TR-41.6.1 meeting was mainly with Ericsson and Lucent. The PWT series of standards is based in large part on ETS 300 175 (DECT). Lucent and Ericsson indicated they have patents that may be pertinent to the PWT standards. TR-41.6.1/98-08-05, Letter ballot responses to PWT-E, SP-3614-1 (Personal Wireless Telecommunications - Enhanced Interoperability Standard) were as follows: • 8 “yes” votes, from the Siemon Company, RELTEC Corp., Ericsson, MXCom, Bellcore, NEC, GTE, and CSI Corporation. • 2 “no” votes with comments from Lucent and Motorola. • 2 “no comments” from TCE and Qualcomm. TR-41.6.1 will work to resolve the “no” ballot comments between August 19 and the next meeting of TR-41.6.1, scheduled for November 14, 1998. The document is scheduled for approval at that meeting.

PWT TEST SPECIFICATIONS SP-3951 (Personal Wireless Telecommunications: Physical Layer Conformance Tests) has not been sent out by TIA for balloting due to problems with printing the document and missing figures. W. Cruz (Lucent) will send B. Zidek- Connor (TIA) an RTF version of the document with the figures. The Telephony Applications Test Specification, SP-3949 (Personal Wireless Telecommunications: Speech Coding and Transmission), to be published as TIA/EIA-662-10c, was approved for industry balloting. SP-4079, PWT DATA TR-41.6.1 received the following letter ballot responses for SP-4079 (Personal Wireless Telecommunications: Data Services Profile, Base Standard Interworking to Connectionless Networks): • 0 “no” votes. • 7 “yes” votes from Ericsson, MIS Labs, NEC, Teltec, Bellcore, Lucent, and CSI Telecommunications. • 3 “no comments” from Siemon Co., Qualcomm, and GTE. The working group recommended that the document be approved as a standard. P. Murray (Ericsson) will make editorial changes to correct the references to TIA/EIA-662 and remove the word “draft.” SP-4199, PERSONAL WIRELESS TELECOMS: DATA SERVICES PROFILE C, CLASS 1 TR-41.6.1 approved PN-4199. W. Cruz (Lucent) will make editorial changes to correct the references to TIA/EIA 662-13c. PN-4201, PERSONAL WIRELESS TELECOMS: DATA SERVICES PROFILE C, LOW RATE MESSAGING SERVICE TYPE E, CLASS 2 TR-41.6.1 approved PN-4201, Personal Wireless Telecommunications: Data Services Profile C, Low Rate Messaging Service Type E, Class 2, for industry balloting as SP-4201. P. Murray (Ericsson) will make editorial changes to correct the references to TIA/EIA-662-13f. PN-4200, PERSONAL WIRELESS TELECOMS: DATA SERVICES PROFILE C, CLASS 2 TR-41.6.1/98-08-03, the draft of PN-4200 (W. Cruz, Lucent), was submitted for comments. The work plan is to: • Provide a final draft at the meeting of TR-41.6.1 on November 14, 1998 which addresses comments. • Approve the document for balloting on November 14, 1998, to be published as TIA/EIA-662-13d. TR-41.6.1/98-08-04, draft of Data Service Profile A&B, Class 2 (P. Murray, Ericsson), was submitted for comments. The work plan is to: • Provide a final draft at the meeting of TR-41.6.1 on November 14, 1998 which addresses comments • Approve the document for balloting on November 14, 1998, to be published as TIA/EIA-662-13b. TR-41.6.1 decided to submit a request to TR-41 for a project number for “Data Service Profile F, Class 2, Fax,” to become TIA/EIA 662-13h (Technical Editor’s note: this has become PN-4353). W. Cruz (Lucent) will provide a first draft at the next meeting. ANSI TIA/EIA-662 R EVISION 2 TR-41.6.1 discussed the need to update the PWT standard to reflect changes incorporated in the second edition of the DECT standard. Contributions were encouraged in this area.

TR-41.7 SAFETY AND ENVIRONMENTAL CONSIDERATIONS

T1E1.7 LIAISON

The revisions of T1.313, Electrical Protection of Central Office Facilities, and T1.316, Electrical Protection of Telecommunications Outside Plant Facilities, have been published. The ballot closed on T1Y1-27, Protection of telecommunications links from physical stress and radiation effects, which is being worked jointly between T1E1.5, T1E1.7, and T1E1.8. Work is continuing on the “Electrical Protection of Broadband Facilities” standard. A project on Bonding and Grounding of Telecommunications Network Equipment is underway jointly with T1E1.5.

IEEE 1100 LIAISON Editorial work still remains on IEEE 1100, Emerald Book, Recommended Practice for Powering and Grounding Sensitive Electronic Equipment. The next meeting has not been scheduled. NEC (NATIONAL ELECTRIC CODE) LIAISON The 99 NEC has been finalized. The beginning of the cycle for the 2002 NEC will be the fall of 1999. NAFTA (NORTH AMERICAN FREE TRADE AGREEMENT) CCT (CONSULTATIVE COMMITTEE - TELECOMMUNICATIONS [TRILATERAL]) LIAISON No change reported. The next meeting of the Product Safety Group is tentatively scheduled for September in Toronto. TR-41.9 LIAISON TR-41.9 requested that TR-41.7 explain the meaning of the “front time” used in the harmonized FCC Part 68. The Front Time and Rise Time definitions were presented to TR-41.7 and approved. A contribution based on the discussion will be provided to TR-41.9. Rise time is the time duration for the waveform to move from the 10% point to the 90% point; front time is the time duration from the 0% point to the 100% point of a straight line passing through the most linear portion of the waveform. The recommended points are the 10% and 90% points for a short current waveform and the 30% and 90% points for an open circuit voltage waveform. This means that the rise time is 80% of the front time for a short current waveform and no less than 80% of an open circuit voltage waveform using the points defined above. ANSI/TIA/EIA-631, R ADIO FREQUENCY IMMUNITY REQUIREMENTS FOR EQUIPMENT HAVING AN ACOUSTIC OUTPUT S. Jones (TIA) attended during the discussion of the consumer oriented RF Immunity Bulletin (TR-41.7/98-08-09©). Changes recommended by TR-41.7 were given to S. Jones. She will update the bulletin and provide it to TR-41.7, if possible, before the next meeting. She will contact B. Howden to see if the statistics for the Form 630 check-off for TIA-631 voluntary compliance is available, and check with Global for the number of TIA-631 Standards sold. SP-3283A, TELECOMMUNICATIONS USER PREMISES EQUIPMENT ENVIRONMENTAL CONSIDERATIONS The third industry default ballot for SP-3283, Telecommunications User Premises Equipment Environmental Considerations (to become TIA-571-A), closed July 27, 1998. TR-41.7/98-08-10 is the ballot summary. There were no “no” votes and only one comment (Frank Stein, consultant), on the proper form for the term “dc.” Lucent, who voted no on the last ballot, did not submit a ballot. L. Baker (Chair) met with the Lucent representatives at the meeting; they were satisfied with SP-3283-A-3 and indicated they would change their previous vote to yes on the blue card when it is received. The comment submitter was not present. TR-41.7 recommended that the SP be searched for other forms of the term “dc” and then the form used most be used in all places; it was determined that the lower case “dc” was the only form in the document. SP-3283-A-3 was recommended for publication as ANSI-TIA- EIA-571A. TR-41.7.1 H ARMONIZATION OF INTERNATIONAL SAFETY STANDARDS The May meeting report (TR-41.7.1/98-08-10) was corrected as follows: Section 7, IEC 950, last paragraph second sentence should be. “…Bellcore GR-1089 which allows up to 140 volts to ground, source limited to 100 VA and a 10 milliamp limit to ground from 140 to 200 volts.” BI-NATIONAL SAFETY STANDARD, UL-1950/CSA-950 R. Ivans, representing UL, requested a letter from H. Daugherty (ATIS). The letter should note the following: • It should state ATIS’s interest in having the service providers represented on the UL1950 IAC (Industry Advisory Committee) and the BNTG (Bi-National Task Group). • It should request that J. Brunssen (Bellcore) be that representative. • It should clearly identify the organization to be represented such as The Alliance for Telecommunication Solutions or the Protection Engineers Group.

The Canadian Standard CSA950 second edition has been published in both English and French. The US Standard UL1950 second edition was published a year ago. This edition contains the fourth amendment of the Second Edition IEC 950 but not the Third Edition. This must await the FDIS (Final Draft International Standard) of the Third Edition which is expected in early 1999. IEC 950 (INTERNATIONAL) The Third Edition of IEC 950 has been completed. It will become IEC 60950, Third Edition when published. Final approval and publication of the Third Edition is estimated to be late 1998 or early 1999. Work items on the first amendment of the Third Edition have begun and will be discussed at the next TR-41.7 and TR-41.8 meetings. The USTAG (U.S. Technical Advisory Group) meeting is September 1-3 in Lake Tahoe, CA. TR-41.7.1/98-08-12 contains the preliminary agenda and working papers for this meeting. R.L. Pescatore (Hewlett-Packard) is the convener of TC 74/WG 8: Safety information technology equipment including electrical business equipment. TR-41.9/98-08-65 (for details see TR-41.9 report) on cable modems was discussed briefly. In response, J. Brunssen (Bellcore) and R. Ivans (UL497-C) volunteered to bring information they had on surge requirements for coax systems. Remote power feeding was discussed again. The subject is made difficult because of the conflicting requirements from the many organizations and administrations represented. Also, the powering may be over copper pairs and coax. There are the issues of powering of the outside facilities and power which is allowed into the customer premises. In general, power above 100 VA and voltage above 60 volts will be considered hazardous. ETR 300-012, CENELEC CLASSIFICATION OF TELECOMMUNICATION INTERFACES ETR 300-012, CENELEC (Commission Europeenne de Normalisation Electrotechnique) Document on Classification of Telecommunication Interfaces, contains the common European telecommunication interfaces and a discussion of the application of IEC 950 to each interface. It is unlikely that all North American telecommunication interfaces would be included. In addition, some of the interfaces it contains may not be used in the U.S. It would be useful for TR-41.7.1 to generate a North American version. To this end, it will be an agenda item at the next meeting. Also, it would be useful to gather information on new technology interfaces to add to the NA version of the document. There may be IP (Intellectual Property) issues with these new technologies. LeRoy Baker, RELTEC

TR-41.8, COMMERCIAL AND RESIDENTIAL PREMISES WIRING

TR-41.8.1, COMMERCIAL BUILDING CABLING TIA has developed an on-line balloting system for TR-41 committee members. Ballots for SP-4195-A, PN-4292, PN-3193 and PN-4349 are available on the TIA web site (password controlled). After January 1, 1999, all ballots will be administered electronically with paper copies available at additional cost. For the interim period, ballots will be provided as previously, without charge. UTP SYSTEMS TASK GROUP Comment resolution was to be held on PN-4292 (Additional Transmission Performance Guidelines for 100 Ω 4-Pair Cat 5 Cabling, TSB-95) regarding additional requirements for category 5 cabling. Unfortunately, twenty-five members did not receive their ballots so the ballot deadline was extended until September 29, 1998. Also, several people mentioned that they did not receive a ballot for SP-4195-A regarding requirements for category 5e cabling (enhanced to support 1000BASE-T requirements). Both documents will be reviewed at an interim meeting scheduled for October 1-2 in Montreal, Canada. TR-41.8.1 hopes to resolve all comments at the November meeting. Comment resolution was held on the addendum to TIA/EIA-568-A on hybrid and bundled cable. TR-41.8.1/98- 08-064, SP-3837-A Ballot Comments and Resolutions, reports that all comments were resolved editorially and incorporated into the addendum. TR-41.8.1 agreed to forward the addendum to TR-41.8 for publication. TR-41.8.1/98-08-057-e is the current draft of the category 6 cabling document. TR-41.8.1/98-08-055-e (from the ISO/IEC meetings in Tokyo) provides ISO/IEC descriptions of Class D (new 100 mHz frequency range), Class E (250 mHz) and Class F (600 mHz) cabling, and a contribution to ISO/IEC JTC1/SC 25/WG 3 titled “Overview of Proposed Performance Specifications for Class D, Class E and Class F Cabling With IEEE 802.3ab

1000BASE-T channel requirements NEXT loss, insertion loss, ELFEXT loss, Return Loss Propagation Delay and Delay Skew” (H. Koeman, Fluke Corporation). ANSI/TIA/EIA-568-A is equivalent to ISO/IEC 11801:1995. It was agreed to send two letters to IEEE 802.3. TR-41.8.1/98-08-067 requests the IEEE to provide a 2.5-3 hour tutorial session for TR-41.8.1 regarding future technologies during the evening of November 18, 1998 in Palm Springs, CA (during the TR-41 meetings). TR-41.8.1/98-08-070 (M. Shariff, Lucent) provides changes as to the way category 5 cabling is described in the IEEE-802.3ab/ D4.0 proposed standard on 1000BASE-T. The comments explain that Category 5 specifications plus the additional transmission requirements of return loss, ELFEXT loss and MDELFEXT loss specified in the 1000 BASE-T draft (clause 40.7) are necessary and that additional specifications that ensure a BER of 10-10 are also in progress in TIA and ISO/IEC (Class D). CONNECTOR TASK GROUP The Connector Task Group is working on a test plug procedure and on characterizing balance with a way to measure it. The category 6 connecting hardware has been deferred due to the work involved with these other projects. TR- 41.8.1/98-08-056, Production Modular Patch Cord NEXT Loss-Test Method and Requirements for Unshielded Twisted Pair Cabling (PN-4349), was presented to TR-41.8.1 and modified. TR-41.8.1 then agreed to release the document for committee letter ballot. (Editor’s note: The PN-4349 ballot closes October 5, 1998.) OPTIC FIBER TASK GROUP TR-41.8.1/98-08-058, Fiber Recommendation for TIA-568-B.1 (T. Beam, AMP), adds 50/125 µm fiber as a recognized media to the horizontal and backbone cabling. It was accepted by TR-41.8.1. The current draft of TIA- 569-B.3 permits the use of a variety of traditional and new small form factor (SFF) duplex and multi-fiber connector designs in the main cross-connect, intermediate cross-connects, horizontal cross-connects and consolidation points, provided that the connector design is defined by a TIA Fiber Optic Connector Intermatability Standard (FOCIS), and that the design satisfies the performance requirements specified in TIA-568-B.3 Annex A. This draft also specifies that the horizontal optical fiber cabling be terminated with a duplex SC connector and adapter in the work area. TR- 41.8.1/98-08-059, Work Area Outlet Fiber Connector Requirement (R. Mason, Panduit), proposes the addition of all small form factor (SFF) connectors in the work area; it was not accepted. TR-41.8.1/98-08-060 is the proposal to forward the proposed TIA/EIA-568-B.3 Optical Fiber Cabling Standard to committee ballot. It was accepted. SCTP TASK GROUP TR-41.8.1/98-08-062 requests a default ballot on SP-3193, Technical Specifications for 100 Ohm Screened Twisted-Pair Cabling, to resolve the three specific technical changes resolving comments to Draft 14, with an additional item that corrects an error in the resolution of comments from draft 12. This Standards Proposal is expected to become an Interim Standard once it is approved. TR-41.8.1 agreed to release the document as a default ballot. (Editor’s note: The PN-3193 ballot closes October 5, 1998.) STP-A TASK GROUP The development of a strawman document for TIA-568-B.4 has progressed slowly as it is dependent on the development of TIA-568-B.2. The STP-A Task Group plans to have a strawman, which could include category 7 cabling, by the November meeting. INSTALLATION CABLING REQUIREMENTS TASK GROUP The Installation Task Group will become active again at the November meeting. Several contributions with questions previously raised will be reviewed for inclusion in TIA-568-B.1. IEEE LIAISON REPORT IEEE-802.3z (Gigabit Ethernet over optical fiber) has been approved as a standard and is being edited for publication. IEEE-802.3ab (Gigabit Ethernet over twisted-pair) is out for its first stage ballot and is on track for a March 1999 delivery. IEEE responses to TIA liaison letters will be developed in the September meetings. HARMONIZATION WITH ISO/IEC 11801 The draft document on Category 6 requirements developed in the UTP Systems Task Group (TR-41.8.1/98-05- 050) was reviewed. The US TAG (TR-41.8.1) did not agree to forward the contribution to ISO/IEC JTC1/SC 25/WG3; however, the US TAG Chair did mention at the WG3 meeting that the US is working on category 6

18 Vol. 9.7 Copyright © CSR 1998 October 1998 COMMUNICATIONS STANDARDS REVIEW – TELECOMMUNICATIONS requirements. J. Siemon (Siemon Co.) asked that TR-41.8.1 develop a good category 6 document so that it could be presented at the January WG3 meeting. At the ISO/IEC meeting in Tokyo, chapter 7 on link requirements and two documents on testing were agreed to be released for ballot. At a US TAG teleconference, editors were assigned to compile the US comments to these proposed documents. EDITORIAL TASK GROUP The draft of the proposed TIA-568-B.1 document is a compilation of currently approved and published documents. It was agreed to place editors’ notes in the document as placeholders for laser testing of multimode systems and mode conditioning patch cords. The document will be placed on the TIA FTP site and a schedule developed to have all TIA-568-B documents published by the year 2000. TR-41.8.2, R ESIDENTIAL & LIGHT COMMERCIAL PREMISES DISTRIBUTION TR-41.8.2/98-08-008 lists ballot resolutions on SP-3490-B, Residential Telecommunications Cabling Standard. Overall, there were 178 comments from thirteen companies. Seven companies voted "Yes" with comments (BICSI, Corning, CSA, Essex Group, Ortronics, R.L. Pritchard, Siecor) while six voted "No" with comments (3M, Bellcore, Erico, Lucent, Siemon, VESA). The comments were reviewed, the proposed standard updated, and the resolution to the ballot comments compiled. The results of the resolution of comments required another ballot. These comments primarily concerned definitions, references, sizing of the distribution device space, and revision to the entire section on optical fiber cabling. The optical fiber section is to include all of the small form factor connectors and 50/125 µm optical fiber. Options for singlemode may also be included. The document will be edited via conference call and then re-balloted in time to resolve comments at the November meeting. TR-41.8.3, BUILDING PATHWAYS AND SPACES FOR TELECOMMUNICATIONS TR-41.8.3/98-08-003 lists ballot resolutions of twenty-two technical comments on SP-4198, Addendum to TIA/EIA 569-A for Access Flooring. However, due to schedule conflicts, the editor and several companies commenting could not attend the meeting to support their views. Therefore, the Chair tabled the resolution of comments until the November meeting. TR-41.8.3/98-08-004, Non-continuous Cable Support (R. Kenen, Erico), is a proposal that specifies the surface area a cable support must contain to minimize degradation to cable transmission. TR-41.8.3/98-08-005, Poke-Thru Fittings (Wiremold), proposes to have TIA-569-A (Commercial Building Wiring Standard for telecommunications Pathways and Spaces) recognize Poke-Thrus as a distribution system within buildings. Poke-Thrus are electrical devices that allow through penetration of above grade concrete floors while maintaining the fire rating of the floor. Mechanical and fire-rated specifications are given in the proposal, as well as building design considerations when using these devices. TR-41.8.4, CUSTOMER-OWNED OUTSIDE PLANT TR-41.8.4/98-08-017 lists ballot resolutions on the default ballot of SP-3339-1, Customer Owned Outside Plant Telecommunications Cabling Standard. Twenty-six comments were discussed from fourteen companies responding: 8 Yes (TelCon Associates of St. Louis, ITT canon, MIS Labs, ERICO, Bellcore, 3M, WILTEC, GTE) 4 Yes with comments (Lamson & Sesions, Corning, Essex Group, Siecor), and 2 No with comments (Lucent, Spawar Systems). The comments were reviewed, the proposed standard updated, and the resolution to the default ballot comments compiled. The results of the resolution of comments required that another default ballot is necessary to resolve nine (9) technical comments. These comments primarily concern test methods, adding a chart to the channel lengths supported by optical fiber applications, and including a note about testing with high impedance probes for high frequency applications. Of the two "No" votes received, one was resolved and the other will be addressed in the next default ballot. The one "No" vote was resolved by opening a Project Request for an addendum to TIA-758 on Optical Fiber Cabling Practices. Bob Jensen, dbi

TR-41.9, R EGULATORY CONSIDERATIONS ON TERMINAL ATTACHMENT PROGRAM A. Wride (Chair, TR-41.9) asked members to identify if there was knowledge of patents, the use of which might be essential to the standard being considered. None was identified.

One item was added to the agenda: Exparte Restrictions: the members were advised of the restrictions by FCC staff W. Howden, present at the meeting. The complete set of Exparte Rules (rules of participation) can be found at http://www.fcc.gov/ftp/reference_tools/exparte.txt. TAPAC, TAPAC TTF, TAPAC ATF, LIAISON H. Mar (Industry Canada) reported that on June 30, 1998, CRTC, the Canadian regulators, issued a Telecom Decision 98-8 on local pay telephone to allow competition in the local pay telephone market. Before a new entrant may provide the service, he or she has to register with the Commission and meet all of the conditions for consumer safeguards. Terminal Attachment Program Advisory Committee (TAPAC) will also have to work out the required certification procedures and specification for public pay telephones. Industry Canada has nearly completed new regulations on telecommunications apparatus to make provisions for Canada to take part in various Mutual Recognition Agreements (MRAs). An information session on MRAs and the development of new telecommunications regulations is planned for September 25 - October 2 in various cities across Canada. The next TAPAC meeting will be October 13-14, 1998 in Ottawa. P. Adornato (Nortel) reported that TR-41.2 is continuing to monitor the progress of the EU/US MRA. Official signatures have been obtained and the implementation phase is expected to start officially sometime in October. There will be additional information at the November TR-41.9 meeting. The Asia Pacific Economic Cooperation Forum (APEC) has many activities. PART 68 HARMONIZED STATUS FCC Common Carrier Bureau Public Notice on Suspension of Harmonized P68, dated May 14, 1998 (TR- 41.9/98-08-045) was released by the FCC. It provides the effective date of the Part 68 Harmonized Rules. Enforcement of the amended rules was suspended until thirty days after this Public Notice was published in the Federal Register (June 8, 1998). TR-41.9/98-08-053 (H. Mar, Industry Canada) provides a comparison of Harmonized CS-03 and Part 68. There was discussion of rise time (in CS-03) and front time (in Part 68). A group was formed to clarify “rise time” and “front time”, including J. Bipes (Mobile Engineering), leader, D. Moon (GDC, by correspondence), A. Martin (Raychem), R. Baker (RELTEC), and E. Guevara (Stentor). There was also some confusion concerning the three options in the Pulse Shape Requirements. J. Bipes (Mobile Engineering) will present a proposal to clarify options a, b, c in TSB-31-B (Part 68 Rational and Measurement Guide). H. Mar (Industry Canada) will submit appropriate changes to the TTF (Technical Task Force) so that CS-03 can further be revised and will also revise the comparison table to include the rationale of the differences. ADSL The ballot was sent out on the T1E1.4 Document T1.413 Rev2; the results will be discussed at the upcoming T1E1.4 in two weeks. PCM MODEM TR-41.9/98-08-056 notes to TR-41.9 the work under way in T1A1.7 on PCM modem testing. TR-41.9/98- 08-063 (B. Lerich, Bellcore) provides a copy of T1A1.7/98-019, the meeting report of the PCM modem test plan ad hoc meeting (teleconference April 21, 1998); it includes a test plan to test the output of PCM modems for voiceband interference on subscriber loops. The test plan is being incorporated into a T1 Technical Report. It will include criteria upon which to base a decision to support a waiver of FCC constraints on the signal strength of encoded analog signals input into the public network. Questions were raised on the actual speed of 56 kbit/s. It was noted that the Rockwell web site provides interesting information on this topic (http://www.rss.rockwell.com); it was also mentioned that Europe already uses –6dbm for encoded analog content. R. Rahamin (Rockwell) will provide additional documents on this topic at the next meeting.

PARADYNE REQUEST FOR WAIVER

TR-41.9/98-08-054 P. Walsh (Paradyne) provides a copy of the Paradyne petition for waiver of the signal power limitations contained in Section 68.308(e) of the FCC Part 68 Rules. The purpose of this waiver is to permit the registration of Paradyne’s Hotwire MVL equipment by reconciling certain disparities between Part 68 and CS- 03.

TR-41.9/98-08-052 is the FCC Public Notice DA 98-1358 on Paradyne’s request for waiver. TR-41.9/98- 08-061 provides comments on the Paradyne petition from Alcatel; it raises concerns over spectrum compatibility and suggests delaying any grant of waivers. TR-41.9/98-08-062, the Nortel comments on the Paradyne petition, suggests that any changes to Part 68 should be based on the ANSI T1.413 issue 2. Bell Atlantic also provided some comments concerning the petition from Paradyne. There was a lengthy discussion on the performance specifications of the Paradyne product and on the comments submitted on this petition to the FCC. An ad hoc group was formed to look into this type of technology. Members of the group are: E. Guevara (leader, Stentor Resource Centre), P. Walsh (Paradyne), and P. Adornato (Nortel). ACCESSIBILITY ISSUES S. Crosby (Lucent) reported on Section 255 of the Telecom Act of 1996 issues. All comments have been submitted to the FCC. The response from TIA is available from the TIA web site http://www.tiaonline.org/government/255/. FCC NOI ON NEW TECHNOLOGIES TR-41.9/98-08-055 (FCC Notice Of Inquiry on new technologies) notes that the FCC has released two NOI and one NPRM on the subject of new technologies and how FCC procedures and rules affect new technologies. Members were advised to obtain these documents (Index Numbers: FCC 98-118, FCC 98-187, FCC 98-188) from the FCC web site and review them. Should any member feel that TIA comments are necessary, the TR-41.9 Chair (A. Wride) or the TIA-UPED (User Premises Equipment Division) Chair (P. Adornato) must be contacted in order for a group to be convened to formulate the TIA comments. FCC/IC REQUESTS/ISSUES ON PART 68: Regarding the flow of applications through the FCC Part 68 review process, B. Howden (FCC) gave a presentation on the flow of Application Forms, the sample of the database, and the rules. A. Wride (Chair) will obtain a copy of the slides from the presentation and send them out with the next meeting package. There was some discussion on the rules; TR-41.9 might form an ad hoc group to clarify some of the texts. The revisions can be documented in the Form 730 Application Guide. However, it was mentioned that the FCC already has an Administrative committee chaired by R. Provost (FCC) who deals with the administrative details for Part 68. (Chair’s note: R. Provost has been contacted and, in concert with B. Howden (FCC), has tentatively called a meeting for October 16, 1998. The meeting notice will be sent out to interested parties.) There were some questions on the Harmonized Order and Par. 68. 2(j) concerning the effective date and the grandfathering issues. TR-41.9/98-08-049 is a letter to the FCC from TR-41.9 reviewing the new surge requirements and associated failure criteria. It proposes that the FCC Part 68 staff look for complete applicable test data (1) before stresses, (2) after Type B stresses, and (3) after Type A stresses in all Part 68 applications. B. Corey (Industry Canada) provided a brief report on the contribution and noted that this is only applicable to reverse battery circuit. There was some discussion on Type B surge. One of the main reasons why Type B was considered was because it best simulated the most appropriate environmental test applicable to the product. This lesser surge energy may affect circuits incorporating solid state components in a different manner than would a higher surge energy. The components may be impaired by the lesser energy and may cause compliance problems, whereas the components would be completely obliterated by the higher energy surge, which would then render the interface circuit totally inoperative. This was the rationale for incorporating Type B surges into the Part 68 rules. It was decided that the threshold off-hook current detect from COs for different circuits should be researched. The loop start circuit would be the first to evaluate. A small ad hoc group comprised of G. Page (Intertek) and P. Havens (Teccor) will work on this. TR-41.9/98-08-060 (S. Roleson, Hewlett-Packard) provides a listing of web addresses relating to rural telephony and telecom regulatory resources outside North America. TR-41.9/98-08-064 (G. Page Intertek) is Instructions for importing the FCC Part 68 Data Base into Microsoft Access 97 (ftp://ftp.fcc.gov/pub/XFS_AlphaTest/zipped). As part of her assignment at the last meeting, A. Wride (Chair) contacted NTCA (National Telephone Cooperative Association) but got no response. This was done in order to request information regarding requirements in Part 68 that are relied upon to provide the Part 68 database. Members were asked to try the instructions out and report at the next meeting. TR-41.9/98-08-058 (T. Bishop, Bell Atlantic) provides details (Part 68 changes and coin deposit signal specifications) regarding Central Office implemented pay phones; it proposes that changes be made to FCC Form 730 and TIA TSB-31-B to address CO-implemented pay phones. TR-41.9/97-08-074 is a previous presentation

October 1998 Vol. 9.7 Copyright © CSR 1998 21 COMMUNICATIONS STANDARDS REVIEW – TELECOMMUNICATIONS that described the signaling and Part 68 pay phone issues. FCC Doc 96-388 (adopted 9/20/96) added CO- implemented pay phones to the scope of Part 68, but did not address any of the technical requirements. Some information from Committee T1E1 was also provided. It was proposed to revise the test matrix in TSB 31-B, and to add an Appendix to provide some background and rationale. Once this work is done, there is a need for balloting that portion since this is a technical change. This issue is also being discussed in Canada. There is a plan to proceed similarly to the procedures identified in TR-41.9. There will only be loop start pay phones in Canada. It should be noted that the carriers are asking for specific access interfaces from the manufacturers. A small working group consisting of G. Slingerland (Mitel) and T. Bishop (Bell Atlantic) will work on this and report back at the next meeting. A. Wride (Chair) will contact a manufacturer of pay phones to ask for participation (Mars International). TR-41.9/98-08-057 is a TSB-31-B errata compendium. G. Slingerland (Mitel) provided a summary of his report. All items are editorial changes. For Item 8, the solution should be “None.” For Item 9, the solution should also be “None.” A. Wride (Chair) will ask TIA about the guidelines for indicating the company and the representative listed in the TSB-31-B. TR-41.9 TECHNICAL OUTPUTS (“DEAR BILL” CORNER) A. Wride (Chair) will continue to work on this and will consult with B. Howden (FCC).

OTHER HIGHLIGHTS TR-41.9/98-08-065 (P. Havens, Teccor) provides a good overview on cable modem systems. It contains a list of North American cable modem systems including equipment vendor and service offered and cost, a list of international cable systems with equipment vendors, discussion of the 802.14 and Multimedia Cable Network System (MCNS) Data Over Cable Service Interface Specification (DOCSIS), list of equipment suppliers, and surge protection requirements (UL-497C effective October 1, 1999 and ISCTE specification IPS-SP-204). It appears that cable modems are not subjected to Part 68 rules since the connection to the PSTN is located at the head-end. TR-41.9/98-08-044, presented by P. Adornato (Nortel), is the FCC NPRM (GEN Docket 98-68) on streamlining the equipment authorization process by providing the option for private sector approval. It is expected that the FCC will issue a Report and Order in October. TR-41.9/98-08-055 concerns the FCC NOI on new technologies under CC Docket 98-94 documents: FCC 98- 118, 98-187, 98-188. The FCC solicits public comment on the effect of FCC regulations on technical trials and market trials. All members were encouraged to review these documents and provide comments. If interested, please send comments to A. Wride (Chair). TR-41.9 revisited the new technologies list in the last meeting report (TR-41.9/98-08-043) and determined that there is still a need to further review and formulate TR-41.9’s goals with more specifics. There was a discussion on the scope of TR-41.9. TR-41.9 might consider changing its scope. This item needs to be recorded and further discussed since future work will be based on it. A. Wride (Chair) will obtain the scope of TR-41.9 from TIA and attach it to the next meeting notice. Anh T. Wride, Director of Engineering, CCL

TR-41.10, PRIVATE INTEGRATED SERVICES NETWORK (PISN) TR-41.10 reviewed the following: • ISO/IEC JTC1 SC6 N10886 (PISN Mobility - General principles and services aspects, TR15410) • ECMA “PISN/VoIP Framework of Interest” document REVIEW OF ISO/IEC JTC1 SC6 N10886 TR-41.10/98-08-031 is a report of the last ISO/IEC JTC1 SC6/WG6 meeting held during May 17-21, 1998 in Seoul, Korea. M. Zonoun (Nortel) and M. Shah (Lucent), who attended, provided a page by page walk through of this 35 page meeting report. The following are the key points from the discussion: Mobility The project editors for QSIG Mobility documents will distribute the following six documents for FDIS (Final Draft International Standard) ballot after the FCD (Fast Track Committee Draft) ballot deadline of June 2, 1998, based on the agreed resolution of these documents at the Seoul meeting. If, upon close of the FCD ballot (6/2/98), it is discovered that additional comments have been submitted, the editor will prepare a revised disposition of comment report covering those comments. The following FCD ballot documents are posted on-line on the TIA TR-41.1 site (password protected), http://ftp.tiaonline.org/TR-41/TR-41.1/ : TIA # TR- ISO/ TITLE 41.10/98- IEC # 08-032 15428 Mobility: Location Registration supplementary services 08-033 15429 Mobility: Location Registration protocol 08-034 15430 Mobility: Call Handling additional network features 08-035 15431 Mobility: Call Handling additional protocol 08-036 15432 Mobility: Authentication supplementary services 08-037 15433 Mobility: Authentication protocol During final plenary, M. Zonoun (TR-41.10 chair) asked TR-41.6.1 (Personal Wireless Telecommunications) and TR-41.6.3 (PACS-WUPE) chairs to notify other members about these documents. TR-41.10 needs to have their concurrence to adopt these ISO standards as ANSI standards. PUM During the ISO meeting, ECMA distributed the following documents on Private User Mobility (PUM). These documents were posted on-line after the meeting on TIA TR-41.1 site: TIA # TR- PUM TITLE 41.10/98- 08-038 PUM: Location Registration supplementary services 08-039 PUM: Location Registration protocol 08-040 PUM: Call Handling additional network features 08-041 PUM: Call Handling additional protocol During the ISO meeting, ECMA representatives queried other delegates for support to submit these documents via fast track procedures. The US delegates requested delaying fast track submission, so that TIA TR-41.6 has a chance to submit Stage 1 requirements on Private User Mobility to ECMA. During the TR-41 plenary, M. Zonoun asked TR-41.6.1 (PWT) and TR-41.6.3 (PACS-WUPE) chairs to notify other members about these documents. TR-41.6 needs to provide comments on these four documents and to provide Stage 1 requirements for PUM-based on their earlier work on this subject, so a liaison statement can be sent to ECMA to incorporate US-specific requirements prior to submitting these documents to ISO through fast track. QSIG SS/ANFs At the ISO meeting in Seoul, the following PISN documents were agreed for publication to the next state:

ISO # SC6 # TITLE IS 13874 2nd edition 6N 10718 Path Replacement protocol, 2nd edition IS 13873 2nd edition 6N 10717 Path Replacement service description, 2nd edition IS 15992 6N 10720 Call Priority Interruption protocol IS 15991 6N 10719 Call Priority Interruption service description IS 15772 6N Common Information protocol 10810_rev IS 15771 6N Common Information service description 10809_rev IS 11571 2nd edition 6N 10823 PISN Numbering and Addressing TR 15410 6N 10888 Mobility: General principles and service aspects DCOR1 15052 6N 10891 DCOR1 to Recall protocol FCD 11579-3 6N 10892 Reference Configuration – Part 3 Extension Line DCOR1 13873 6N 10778 DCOR 1 to Call Diversion protocol DCOR1 13869 6N 10779 DCOR 1 to Call Transfer protocol TR-41.10 will determine when to adopt these ISO standards and when to publish them as ANSI standards. M. Shah (Lucent) will handle editorship for DCOR1 (Draft technical Corrigendum) for Call Diversion and Call Transfer protocol documents in the absence of S. Rengasami (current Editor). M. Zonoun (Nortel) will forward ballot responses to M. Shah, so if needed M. Shah can prepare Disposition of Comments report and revised text. P. Weismantel (NEC) indicated that he would be bringing in a contribution on “On demand circuit switched QSIG connection over ISDN” (based on Bellcore specification TR303). B-QSIG SS/ANFs At the ISO meeting in Seoul, the following documents were supported for publication to the next state: ISO # SC6 # TITLE IS 15899 6N 10818 B-PISN Broadband connection oriented bearer services service description IS 15773 6N 10745 B-QSIG Transit counter During ISO meeting in Seoul, Mr. Volzke gave a presentation on “Circuit emulation of basic access by ATM networks;” ECMA delegates expressed their desire to fast track this document to ISO. The US delegates objected to this proposal based on the fact that earlier efforts (two times) to bring this proposal at ATM Forum were rejected by the ATM Forum’s CS and RA (Control Signaling and Routing & Addressing) group. If TR-41.10 members want to support this work according to the previously established US position on B-QSIG work items, then TR-41.10 should bring this work back into the ATM Forum (with an endorsement of TR-41.10). VoIP M. Zonoun (Nortel) provided a summary of the VoIP discussions that occurred at the ISO meeting in Seoul (see attachment 7 of the ISO/IEC JTC1 SC6 N10886 meeting report, TR-41.10/98-08-031). The WG6 members agreed at the ISO meeting to study interworking between PISN and H.323.IP networks, with a view to identifying any enhancements to H.323 and related standards or PISN standards. WG6 has established an email exploder (run by WG6 secretariat in Australia) for members to identify issues and resolutions by email. Next ISO Meeting The next ISO/IEC JTC1 SC6 meeting will be held January 10-14, 1999 in Sydney, Australia. REVIEW OF ECMA “PISN/VOIP FRAMEWORK OF INTEREST” DOCUMENT TR-41.10/98-08-029 (J. Elwell, dated July 23, 1998) covers two scenarios for circuit/packet interoperation: “interworking” and “trunking or tunneling.” TR-41.10 discussed these scenarios and possible short term and long term strategy.

The majority of the group expressed interest in both scenarios and envisioned “trunking or tunneling” as the short- term solution, and “interworking” as the future solution. M. Zonoun (Nortel) mentioned that IETF has a RFC called “L2TP” which can be a potential solution for the “trunking or tunneling” scenario. P. Melton (Cortelco) expressed concern for finding proper registration authority for assignment of MSI (Manufacturer Specific Information) codepoint value for US-based company. He will bring a contribution to the next meeting with specific background and issues regarding this problem, so TR-41.10 can send a proper liaison to ANSI or ECMA. Mo Zonoun, Nortel

REPORT OF ETSI TIPHON (TELECOMMUNICATIONS AND INTERNET PROTOCOL HARMONIZATION OVER NETWORKS) MEETING #9, AUGUST 31 – SEPTEMBER 3, 1998, PORTLAND, OR Note: Individual copies of standards from the European Telecommunications Standards Institute (ETSI) can now be accessed and downloaded free of charge via the internet: http://www.etsi.rd/eds. The TIPHON Chair is H. Schink (Siemens). TD-01r2 is the meeting agenda. TD-05 is the TIPHON 8 meeting report (June 16-19, 1998, Helsinki, see CSR-T 9.6). The chairman reminded all participants of ETSI’s IPR policy; no IPR announcements were received. Information about previously announced IPR is available at http://www.etsi.fr/ipr/. ETSI documents are available at http://docbox.etsi.fr/tech-org/tiphon/Document/tiphon/. Goals for this meeting (TD-01r2) include: 1. DTR/TIPHON-00001 (Description of technical issues) provided as stable draft 2. DTR/TIPHON-01002 (Requirements for service interoperability; Scenario 2) provided as stable draft 3. DTS/TIPHON-02002 (Network architecture and reference configurations; Scenario 2) provided as stable draft 4. DTS/TIPHON-03002 (Call control flows for basic calls from an H.323 terminal to a PSTN/ISDN/GSM terminal) to be approved by WG 3 and TIPHON 5. DTS/TIPHON-03003 (Call control flows for basic calls from an H.323 terminal to PSTN/ISDN /GSM terminal involving multiple domains) provided as first draft 6. DTS/TIPHON-03004 (Interdomain Pricing, Authorization and Usage Exchange) to be approved by WG 3 7. DTS/TIPHON-04002 (Naming and Addressing; Scenario 2) to be approved by WG 4 8. DTR/TIPHON-05001 (General aspects of Quality of Service [QoS]; Scenario 1) to be approved by TIPHON 9.

12. DTR/TIPHON-02004 (Analysis of existing roaming techniques applicable to TIPHON mobility services) provided as first draft In the descriptions above, Scenario 1 is interworking from IP Terminals to SCN Terminals; Scenario 2 is Interworking from SCN Terminals to IP Terminals. In response to copyright issues, the plenary approved a change in the Temporary Document template for TIPHON. The new template asks TD authors to specify whether or not they want their contribution to be made publicly available on the TIPHON ftp server (public availability of all TIPHON documents had been decided by the ETSI board on request of TIPHON 7). MARKETING B. Castle (3Com), TIPHON Vice Chairman, reported about recent and coming events with participation of TIPHON officials as speakers. A press release drafted at the last meeting has been published by ETSI. TD-45 contains a detailed list of conferences in which TIPHON representatives were involved between the Helsinki (June) and the Portland (August) meetings, and an open list of upcoming conferences and events. As TD-45 is not exhaustive and focuses mainly on Europe-located events, anyone aware of events that should be added to this list is invited to contact B. Castle ([email protected]). STF ACHIEVEMENTS TD-27 (G. Kimchi, R. Scholl, ETSI) provides a detailed report from STF 114 since the last TIPHON meeting. TIPHON expressed its satisfaction with the impressive STF (Specialist Task Force) achievements. G. Kimchi, R. Scholl, and G. Körbler, the three specialists working full time for EP (ETSI Project) TIPHON, have produced a number of significant contributions to the project. Their work has covered areas such as network testing, database scalability study, gateway decomposition study, numbering, etc. The participation of the three STF members in the recent IETF meeting has also proved useful. TIPHON was recognized through its presentations given by the STF, and noted its impact on the work of the IETF. New presentations on TIPHON’s work received more interest than ever before. G. Kimchi reminded the group that the STF earlier received commitments from manufacturing members to provide the STF with equipment for testing. Unfortunately the STF hasn’t yet received anything. IETF REPORT Verbal reports were given by L. Spergel (Lucent), S. Petrack (VocalTec), M. Holdrege (Ascend), and G. Kimchi (ETSI STF 114) on the 42nd IETF meeting. The more relevant items for TIPHON are as follows: There was a TIPHON presentation at the SS7-internet BoF (Birds of a Feather) meeting. It is expected that two new working groups and one mailing list will be created : • One WG on SS7 transport over IP • One WG on IP Device Control ( IPDC) protocol, (a family of standards), SGCP (Simple Gateway Control Protocol ) • One mailing list on RSGP (Reliable Signaling Gateway Protocol), Q.931+ to present a final draft either in October or March to SG11/Q11 The AAA BoF noted IETF’s interest in protocols for Authorization, Authentication, and Accounting. TIPHON WG4 presented at the E.164 to IP BoF mapping (chaired by S. Petrack, VocalTec); no new working group is being formed right now. The DIFSERV WG seems to have reached stable work on ways to differentiate services bits in the IP header. The output of this IETF meeting encourages TIPHON to continue providing its documents as inputs to the IETF community, and to check the usability of IETF’s specifications for TIPHON. LIAISONS TD-32 (A. Dilber, Co-Chair MSAF Internet Services Study Group, AT&T) contains a liaison/presentation from MSAF (Multimedia Services Affiliate Forum) on “several technical areas.” The presentation recommends liaison between MSAF and TIPHON WGs, the main goal being not to trade documents but to communicate to standards

developers the needs and requirements of the network operators and the equipment providers for the global IP services. This view was explicitly supported by L. Spergel (Lucent) and the entire meeting. Although no official liaison has been sent to the IETF, TIPHON should continue good relations by following the IETF reflectors and sending representatives to meetings for presentations. Especially when submitting documents to the IETF, TIPHON should state and explain clearly the type of the document, its state, and its origin in order to avoid confusion between permanent documents, drafts, TDs, etc. TD-38 (F. Abbas and L. Buchsbaum, INTELSAT) contains a liaison/presentation about “Voice over IP, satellites, and thin route telephony.” During the presentation, INTELSAT outlined the potentials of VoIP when used in combination with satellite communications for the provision of thin-route telephony to areas of the world not adequately served by terrestrial facilities. As contemplated, voice/fax services would be provided in combination with other services, such as electronic mail, WWW access, videoconferencing, etc. over a common IP platform. INTELSAT emphasized that rural communications are an excellent starting point for VoIP technology, due to its characteristics of great price sensitivity, generally lower voice quality requirements, less regulatory issues, etc. As such, INTELSAT requested that satellite communications, in particular through VSAT networks, be considered as part of the architecture of the TIPHON project. INTELSAT also provided some insight into its related activities in the field, and expressed interest in participating in the TIPHON-Net trials, by extending its reach to a remote location of the world by deployment of a small VSAT terminal accessing the network through one of its satellites (see diagram in TD-38). Further details are discussed in WG 6 (see below). WG 1, REQUIREMENTS The chair of Working Group 1 is L. Klostermann (Ericsson). TD-12 is the WG report. WG1 is working on DTR- 01002, Requirements for Service Interoperability. CDR (CALL DETAIL RECORDING) TD-50 (R. Eaden, BT) contains a section on the proposed mandatory and optional CDR parameters (with respect to DTS/TIPHON-03004, Interdomain Pricing, Authorization and Usage Exchange). The proposed mandatory set was considered incomplete, it was decided to go through the list in DTR01002 and decide parameter by parameter. The result is incorporated in the latest version of the document. (See also the WG 3 report, below.) HIGH LEVEL ARCHITECTURE Inspired by TD-36, Functional Partitioning of SCN(switched circuit network)/Packet Gateway (L. Spergel, Lucent) and TD-62, The Need for Reference Point N (F. Andreasen, Bellcore), it was decided to include some general statements on modularity, scalability and upward-compatibility of the architecture in the assumptions section. This is considered as a guideline for the WG2 work, rather than as a requirement for TIPHON-compliant systems. MEDIATION TD-60, Mediation for Network Architecture (C. Celiberti, Bellcore) notes the issue of mediation (e.g., message accounting/billing/charging information into network internal or inter-domain format CDRs). Although it was acknowledged that this is indeed an important issue, what TIPHON should standardize in this field was questioned. SECURITY Several proposals on security profiles were received: TD-41, Proposed Annex G/H.235: Exportable Profile (J. Toga, Intel) TD-48, Suggested Text for Security Profiles (S. Thomas, TransNexus) TD-54, New Security Profile to be Added to Annex F/DTS-03002 v1.6.1 (J. Holm, Ericsson) TD-57, Proposed WG3 Authentication Profile (S. Sengodan, Nokia) TD-64, Revision of TD-48, Suggested Text for Security Profiles (H. Brockhaus, Siemens) The chair raised the issue of how the profiles are related to the security architecture, including reference points in the WG2 documentation, and what should be captured in the requirements document. After some discussion it was decided to raise the issue in the security discussion, and await the result of that discussion.

MOBILITY TD-68, Mobility and Virtual Home Environment (VHE) for VoIP (L. Klostermann, Ericsson), suggests that mobility should not be considered for basic call only, but that VHE should be considered right from the start. VHE is the capability for a service provider to offer provider-specific services when subscribers are roaming; the contribution compares several possibilities for implementation. There was consensus on this high level requirement that VHE should be possible. There was hesitation to include the more detailed requirements. There was consensus to forward the main idea of this contribution to SG16, without the detailed requirements. DRAFTING There was some additional drafting on the deliverable (DTR-01002, Requirements for Service Interoperability). Some high level numbering requirements were included from WG4 (TD-44 [S. Rulfs, Deutsche Telekom] comments on the use of IP-address compatible numbers), an informative role model was included in Annex A (Business Roles), Annex B was deleted, and the technical and editorial suggestions in TD-67 (K. Sambor, Telekom Austria) were included. Per requirement, an optional/ mandatory/conditional tag was given. WG 1 ACTIONS LIST The following action items were identified for TIPHON WG1, to be completed for the next TIPHON meeting (#10): • Continue work on mobility requirements • Bring Annex C (traces requirements) up to date WG 2, ARCHITECTURE The chair of WG 2 is J. Vandenameele (Alcatel). The agenda is TD-07. The WG 2 report is TD-13. The major objectives of the WG2 meeting were: • Create a stable draft of DTS/TIPHON-02002 based on the contributions submitted to the meeting. The key topic of this meeting will be functional partitioning of the VoIP Gateway and the new interface(s). • Create a first draft of DTR/TIPHON-02004 based on contributions. The key topic for this meeting is to agree on the basic elements of the report. • Update the list of topics for which contributions are requested. FUNCTIONAL PARTITIONING OF GATEWAY AND DEFINITION OF INTERFACES TD-23, SS7-Internet Interworking - Architectural Framework (M. Holdrege, Ascend), provides the IETF draft of the same name (draft-greene-ss7-arch-frame-01.txt). The document describes an architectural framework for SS7-Internet interworking, onto which existing protocols and future protocols in this space can be mapped. It also provides an ordering of importance for the standardization of these protocols. TD-29, Extending H.323 to Support Control of Media Gateways (G. Kimchi, ETSI), shows how Media Gateway control can be provided using H.323. The creation of a new H.323 entity is not required; only small additions to H.323 framework are required to provide the protocol on the reference point between the Signaling entity and the Media entity. TD-31, Mapping of Gateway Decomposition onto Basic Call Reference Configuration (B. Van Doorselaer, Alcatel), points to some inconsistencies in the draft of DTS/TIPHON-02002 related to the E reference point and the functional partitioning of the Gateway. The contribution then provides a proposal to resolve them. It also proposes to rename Gatekeeper, as this suggests that only H.323 protocols are supported, and proposes Call Control Server as a possibility. TD-36, Functional Partitioning of SCN/Packet Gateway (L. Spergel, Lucent), proposes an architectural framework to support the functional partitioning of the SCN to Packet Network Gateway. It provides descriptions for the several functions as well as an initial list of requirements for the communication between a Gateway Controller and a Media Gateway. TD-49, Framework for the Proposed Gateway Device Control Protocol (E. Zimmerer, Level 3 Communications), presents a framework for the functions required to support the model where the media gateway is remote from the control gateway. It also states that existing protocols such as H.323 do not address the issues involved with this separation and therefore proposes to define a new protocol that controls one or more media gateways.

TD-59, User Multiplexing in RTP Payload between IP Telephony Gateways (B. Subbiah, S. Sengodan, Nokia), describes a means of multiplexing several low bit rate voice streams into a single RTP/UDP/IP connection between IP telephony gateways. It also proposes a new control signaling procedure for negotiating a channel between peer gateways. TD-62, The Need for Reference Point N (F. Andreasen, Bellcore), justifies the need for the functional partitioning of the TIPHON Phase 1 H.323 Gateway into a Signaling and Media part (in SS7 the signaling and media plans are separate) and hence the requirement for the new reference point proposed in the current draft of TIPHON-02002. It also stresses the need for supporting SS7 connectivity. The major part of the meeting was spent on defining the partitioned Gateway. During a drafting session chaired by the editor, B. Van Doorselaer (Alcatel), the several proposals were discussed. From this discussion the editor created a proposal for new text for the Deliverable (TD-78, Results of TIPHON 9 WG2 Drafting Activities). The Gateway that was defined in the Phase 1 document as one functional block now contains three parts: the Media Gateway, the Media Gateway Controller and the Signaling Gateway. After some discussion, it was agreed to use the new text as contained in pages 1 to 7 of TD-78 as the strawman proposal for the Gateway sections in DTS/TIPHON-02002. This text contains a number of inconsistencies and some delegates could not agree with some of the details of the proposal. PROTOCOLS FOR THE NEW INTERFACES TD-24, Reliable Signaling Gateway Protocol (M. Holdrege, Ascend), provides the IETF RSGP draft (draft-ong-rsgp- info-00.txt). This protocol is proposed to be used between a Network Access Server and a Signaling Gateway and supports Call Control, Circuit Management and Resource Management. TD-43 (V. M. Kailasa, R. Gupta, Trillium Digital Systems) proposes a mapping between H.323 messages and ISUP messages for basic services. It also suggests that the mapping proposed be included in some appropriate TIPHON specifications. TD-63, Using SGCP Version 1.1 for Reference Point N (F. Andreasen, Bellcore), provides the current IETF draft SGCP (Simple Gateway Control Protocol) (draft-huitema-sgcp-v1-1-00.txt). It proposes the Simple Gateway Con- trol Protocol for the new interface between the Signaling gateway and the Media gateway. It recommends establishing a liaison with the IETF WG where SGCP work is occurring. WG 2 agreed to not discuss the use of specific protocols at this stage, but to concentrate on the definition of the reference points first. OTHER CONTRIBUTIONS ON ARCHITECTURE TD-38 (F. Abbas and L. Buchsbaum, INTELSAT) contains a liaison/presentation about “Voice over IP, satellites, and thin route telephony.” It provides the block diagram for a VoIP demonstration. The diagram makes use of Satellites providing connectivity between VoIP access devices. It is not clear from TD-38 which amendments are proposed to the Deliverable. INTELSAT was requested to provide a specific proposal referring to the current version of the deliverable. MOBILITY AND ROAMING TD-30 (E. Martinex, PSE Motorola) provides inputs to most of the sections of DTR/TIPHON-02004 including user roaming scenarios, network reference configuration, roaming technologies, IMT-2000 and QoS. TD-68, Mobility and Virtual Home Environment for VoIP (L. Klostermann, Ericsson), describes and compares three different scenarios and proposes to separate the functionality required for VoIP in three parts, i.e., the Location Management Function, the Call Control Function (Gatekeeper), and the Value Added Services Function. UPDATE OF TOPICS FOR FURTHER CONTRIBUTIONS • Issues involved with the distribution of Media Gateway devices and their relationship with the Signaling Gateway that is common to a number of Media Gateways; OPEN – Comments on the current sections of the 02002 document are solicited. • The information flowing across the reference point between the Signaling Gateway and the Media Gateway; OPEN.

• Mapping of code points between Signaling System No. 7 and H.323 - H.225 - H.245 within the Signaling Gateway; OPEN – A clear understanding of this issue is needed; contributions regarding requirements are solicited. • The role of IN to provide interoperability functions; OPEN – refer to back-end services • Architectural model on Accounting/ Charging/Billing (asked by WG1) covering functions within the functional blocks, and their relationships; OPEN – Contributions are solicited. • NEW: Interoperability with mobile networks – Contributions are solicited. PROGRESSION OF DTR/TIPHON-2004 WG 2 agreed to update the section 5 (network reference configuration) of the Deliverable based on text provided in TD-30 (E. Martinex, PSE Motorola). Contributions are requested for the next meeting on the other sections. D. Gurle (VocalTec) will produce a new draft. WG 2 also agreed to align its activities with the work done within ITU-T Q.5 of SG11 (Intelligent network capability sets). L. Spergel (Lucent) will draft a liaison statement together with D. Gurle (VocalTec). In addition, close cooperation will be established with the ETSI technical bodies active in the area of UMTS (Universal Mobile Telecommunication System), especially SMG (Special Mobile Group) and NA (Network Aspects). WG 3, CALL CONTROL The chair of WG 3 is S. Petrack (VocalTec). The WG report is TD-14. The following two deliverables were approved at the working group level: • DTS/TIPHON-03002, Call Control Flows for Basic Calls From an H.323 Terminal to an SCN Terminal • DTS/TIPHON-03004, Inter-Domain Pricing, Authorization and Usage Exchange DTS/TIPHON-03002 TD-25, Amendments to DTS/TIPHON-03002 V1.6.1 (G. Meyer, Siemens), was accepted with the following changes: • A minor change was made in the definition of access token. • The normative references are to be included as normative only if they are normatively included within the text. • Letters such as “F” and “O” should not be included within the abbreviations. The STF will deal with these editorial matters. TD-51, ETSI Modification of Annex A (Required support of H.225.0 call control protocol-normative) to TIPHON/DTS-03002 1.6.1 (J. Holm, Ericsson), was accepted; slightly altered text was included by the editor. Gateways which interwork with ETSI DSS1 are not to send Information Elements not understood by that standard. User Information message is called Information in the Implementor’s Guide, and a note should be made to this effect. TD-52, Comments on DTS03002 V1.6.1 Authentication Registration Procedures (J. Holm, Ericsson), suggests a modification on the Authentication Registration procedures to make mandatory the GRQ/GCF message when Au- thenticating user/endpoints using H.235. After some discussion, it was agreed to replace section 5.3.2 Authenticated Registration with the sentence: Authenticated Registrations shall be in accordance with the security profiles of the security Annex F. The Table might become a part of particular security profiles. TD-53, Modified Error Handling in TIPHON/ DTS-03002 v1.6.1 (J. Holm, Ericsson), proposes a modification of the Basic Call Setup to avoid the possible exposure of trusted elements in a network. It was agreed to add the Note about security policy to section 5.4.6 (the “alternative version” of the proposal). TD-54, New Security Profile to be Added to Annex F of DTS 03002 v1.6.1 (J. Holm, Ericsson), suggests a new security profile intended for “old” version 1 H.323 Terminals. Security Profile F2 will be folded into the “null” profile F1. Text will be added to the F.1 table specifying that security means outside the TIPHON specification may be used.

TD-55, Comments on DTS/TIPHON-03002 v1.6.1 (S. Moore, Siemens), was reviewed in detail, and all the suggestions were incorporated into the deliverable, with the following exceptions: • The RAS message names will be added to the abbreviations. • Comment 4.c.4 is not applicable, since section 5.3.2 has been altered. • Comment 4.d – new text for 5.4.6 is now in the editor’s text. DTS/TIPHON-03004 TD-50, Comments on ETS/TIPHON-03004 (R. Eaden, BT), was considered in detail, although no BT representative was present. The contribution requests many changes to the draft deliverable. Each change was accepted, except that certain features which were requested to be deleted were made optional. The issues raised by TD-50 were addressed as follows: • Removal of authorization feature. The BT concern is that most clearing house functions cannot respond to this type of function within the response time required for call set up. It was noted that the authorization feature is not limited to per-call operation but may be used, for example, to pre-load bulk authorization tokens, in which case the authorization does not occur during call set up. It was further noted that the authorization feature is optional in the specification and need not be used in deployments where it is inappropriate. • Integrating with existing billing system format. Annex F (informative) was added to the specification. Annex F includes a sample program that demonstrates the conversion between the specification’s UsageIndication and the CDR format used by VocalTec’s Internet Telephony Gateway 3.1 • Which components are mandatory and which are optional. The XML DTD (document type definition) notation indicates which XML (eXtended Markup Language) elements (and, therefore, components) are mandatory and which are optional. To make this clearer, Annex G (informative) was added. Annex G provides an overview of XML and the DTD notation. • Optional signature. This proposal was accepted, and the latest draft of the specification reflects the change. ADDITIONAL CONTRIBUTIONS The following documents were presented, but no action was required or taken: TD-37 (G. Kimchi, ETSI) presents a method to assign an E.164 number to IP hosts, based on an analysis of the IP address of the host. It is intended to work even with hosts whose IP address is allocated dynamically, based on the network and subnetwork parts of the address. TD-39 is a presentation of SMG11, “Speech Aspects” activities. No one from SMG11 came to present the TD, but WG 3 attention was directed to the slides of “Tandem Free operation.” WG 3 should consider if some signaling needs to be added, either within H.323, or somewhere else in a TIPHON system, to indicate that the system is capable of Tandem Free Operation, or that it is in use. Bellcore presented a contribution from Pulver MOU (TD-61, C. Celiberti and C. Ford, Bellcore) which proposes a standard structure for an extensible CDR for billing of IP Telephony services. The proposal concentrates on what information is to be included rather than on any particular protocol for presenting or transporting the information. WG 4, NAMING, ADDRESSING The chair of WG 4 is L. Spergel (Lucent). The WG 4 report is TD-15. The objectives of the WG 4 meeting were to support the SG2 activities, to approve the 04002 deliverable, and to review database technology in support of proposals within the 04002 deliverable. SG 2 ACTIVITIES TD-70 (R. Stastny, OEFEG/PTA) contains reports from the previous SG2 Q1/2 (Applications of numbering and addressing plans for fixed and mobile services) and Q10/2 (Management and development of PSTN-based telecommunication services) Rapporteur meetings (June 15-16, Torino, Italy).

DTS-04002 The following TDs relevant to DTS-04002, Naming and Addressing - Scenario 2, were reviewed: TD-37, Architecture for E.164-IP Assignment and Resolution: Replacement Text for DTS/TIPHON-04002 Annex C (G. Kimchi, ETSI STF 114) TD-44, Proposal for Global Numbering Plan for TIPHON-Numbers (S. Rulfs, Deutsche Telekom) TD-46, Address Resolution for Flat Number Space (O. Hersent, France Telecom) TD-47, IETF-references with respect to IP-addressing for DTS/TIPHON-04002 (R. Scholl, ETSI STF 114) TD-56, Comments on DTS/TIPHON-04002 v1.1.4 (S. Moore, Siemens) Since there were many new contributions and many new delegates who represent service providers, it seemed unreasonable to approve the document in this meeting. The document will be delayed until the January, 1999 meeting. SPECIAL SESSION ON DATABASES The purpose of this special session was to investigate the feasibility of the database proposals to support global numbering solutions. In the session, requirements and assumptions were reviewed. The STF will investigate database solutions based on existing technology and create a white paper on this topic. This white paper will be used in support of finalizing 04002 and in support of the SG2 effort. OTHER TOPICS In discussions, it was proposed that there will need to be some type of MOU or carrier agreement to manage numbers within the global code, if it is granted. Some examples of successful, similar situations are 800 numbers within the US, the GSM MOU (Global System for Mobile Communications Memorandum of Understanding), and IANA (Internet Assigned Number Authority). While this MOU cannot be created within TIPHON, TIPHON can make suggestions to support its creation. Interested operators are encouraged to pursue this. There were significant discussions on the topic of service portability, moving service between IP telephony and traditional telephony (or even wireless) while keeping the same number. In the September, 1997 meeting, it was decided that this is not a requirement, however, these discussions indicate that this decision needs to be revisited. Contributions are invited. TD-33, Incorporation of GIDS (Global IP Directory Service) Trial in EU project TIPHON-Net (R. Stastny, OEFEG/PTA) proposes setting up a small scale database for testing within TIPHON-Net. This was presented for information and was also discussed in WG 6. In discussions, it was proposed that if the global code is not granted, similar functionality can be performed using an access code or 2-stage dialing. This could still utilize a similar global database solution. LIAISONS No liaisons were received. It was agreed to send a liaison to the ETSI Task Force on number portability and to the ANSI group on this topic requesting information on the most common architectures for number portability so that TIPHON can investigate interworking with them. It was noted that this topic will need to be considered by WG1 and WG2 in addition to WG4. WG 5, QUALITY OF SERVICE The chair of WG 5 is B. Castle (3Com). The WG 5 report is TD-16. The main goal of the meeting was to review and approve deliverable DTR/TIPHON-05001 V1.2.4, M. Buckley, Lucent Technologies General Aspects of Quality of Service - Scenario 1. TD-39 is a presentation of ETSI SMG11 (wireless GSM and UMTS, speech aspects) activities. DTR/TIPHON-05001 V1.2.4 Deliverable 05001, General Aspects of Quality of Service - Scenario 1, was reviewed. It was agreed to delay the addition of sections on the E-Model and Objective measurement until the next version of this document. Also, new wording for the scope was submitted and approved. These editorial changes were incorporated into the document which was submitted to the plenary for approval.

TD-22 (M. Bais, KPN Research) provides comments on DTR/TIPHON-05001 v1.2.4. TD-26 (ETSI TC STQ) supports the statements and proposals in TD-22, and adds further discussion/clarification of several points. TD-40 (G. Koerbler, ETSI STF 114) presents preliminary results from the TIPHON-Net tests QoS simulation and evaluation. TD-42 (T. Scheerbarth, I. Kliche, Deutsche Telekom Berkom) provides simulation methodology for various VoIP scenarios including packet loss. It was agreed that the deliverable would make a formal reference to the IETF RTP (Real Time Protocol) RFC which includes a supplementary list of codecs to those listed by H.323. It was also suggested that the scope should make reference to the QoS matrix in I.350 which describes systems in terms of: Speed Accuracy Reliability Establish Connection Transfer Connection dis-establishment Scope should also include wording such as: Quality of Service is important to customers and can be summarized in the above table. This document currently focuses on transmission quality. PRESENTATION OF NEXT GENERATION CODEC TECHNOLOGIES FROM SMG H. Su (Rockwell) presented TD-39 on the ETSI SMG 11 work on codecs. TD-39 reports on the existing GSM codecs (full rate 13 kbit/s, half rate 5.6 kbit/s, enhanced full rate 12.2 kbit/s), tandem free operation, the new adaptive multi-rate codec and UMTS matters. PRESENTATION OF CODEC LICENSING C. Bechamp (Sipro Lab Telecom) presented TD-86 on G.729 codec licensing. This presentation notes that Sipro currently represents France Telecom, NTT, University of Sherbrooke and AT&T for G.729 technology, with other potential IPR owners presently being negotiated. ETSI STQ ROADMAP, EVALUATION OF SPEECH TRANSMISSION PERFORMANCE, THE E-MODEL J. Horrocks (STQ, DTI) and K. Adler (Alcatel) provided presentations on the STQ Roadmap, Evaluation of Speech Transmission Performance, and the E-Model: STQ Roadmap: TD-74 is a figure providing an overview of Speech Transmission Quality. J. Horrocks noted that ETSI STQ (Speech processing, Transmission and Quality aspects) is planning to evaluate speech over the network (based on EG 201 050) transmission quality using G.711, G.723, G.726, G.728, G.729 and the three GSM codecs. Evaluation of Speech Transmission Performance: TD-73 proposes listening only conversational and instrumented evaluation of end-to-end speech performance. The E-Model: TD-72, an overview of The E-Model notes that speech communication quality from mouth to ear for 3.1 kHz handset telephony across networks is defined in ETR 250 (July 1996). This model is used to predict the subjective effect of combinations of impairments using stored information on the effects of individual impairments. Following was a demonstration of an E-Model simulation software package. This system was used by K. Adler to evaluate the estimated values in Table 7 (below) from DTR/TIPHON-05001 Version 1.2.5. He was able to demon- strate that class C devices would not be able to provide adequate QoS under certain circumstances. Aspects related to the synchronization of echo cancellers are not currently included in the E-Model. It was decided to leave the tables in their current form but to investigate the E-Model in more depth at the Tel-Aviv meeting (October 26-30).

Table 7: TIPHON Network Delay Requirements SIGNALING FOR QOS A discussion was held on QoS (Quality of Service) negotiation. Various scenarios were discussed including: • Static Service Level Agreements • Dynamic QoS Negotiation • QoS levels during spot trading of voice The issues involved in signaling for a QoS level during call establishment include: • Feature set negotiation between two terminals • Peer or Network-to-Network negotiation • Signaling from gatekeepers to router devices and relating TIPHON QoS levels to the underlying protocols: Diffserv, RSVP, ATM Other issues were raised including the effects of call forwarding on QoS negotiation and the degradation produced by lower quality GSM devices. TD-69 (F. Burg, AT&T) provides background material on the modeling techniques developed in ITU SG 7 (X.213 network service definition, X.223 provision of the network service layer using X.25), ISO/IEC JTC1 SC 6 and 16/21 (ISO/IEC 8348, 8648, 10028, 8878) and ECMA TC32, in support of Quality of Service negotiation. It was agreed to focus on specific scenarios in order to simplify the discussion; the phase 1 scenario will be used for the initial discussions at the Tel-Aviv meeting. WG 6, VERIFICATION The chair of WG 6 is M. Blaschitz (Infonova). The WG 6 report is TD-17. The main objectives of this meeting were: • Approval of DTR/TIPHON-06001 • Detailed specification of TIPHON-Net test environment and tests • Planning of TIPHON interoperability event ETSI TEN-TELECOM PROJECT IN SUPPORT OF TIPHON The European Governments consider the creation of Trans European Networks (TENs) to be important elements for the European Union: they are incorporated within the EU Treaty. The TEN-Telecom project in support of TIPHON was presented. To avoid any further confusion between WG-6 TIPHON-Net and the TEN-Telecom project, it was suggested to rename the TEN-Telecom project to TTT-Net (“Triple T-net:” Ten Telecom TIPHON Network). A final decision will be made in a meeting with ETSI executives. WG 6 appreciates the initiatives of the TEN- Telecom consortium and believes that these activities will significantly support the work of WG 6 and help the success of TIPHON specifications in general. Since TTT-Net is now preparing its work plan, WG 6 would like to suggest that the following items be covered in the TEN-Telecom project. WG 6 would like to hear the results of these activities. WG 6 would also like to suggest a continuous liaison and an information flow between WG 6 and the TEN-Telecom consortium.

WG 6 suggests that the following items (same as in the WG 6 future test plan) receive high priority in the TEN- Telecom project: • Interoperability of TIPHON-boxes of different vendors (protocol stack interoperability) Test-Spec (PICS) Test-plan from STF. Interop events joint with IMTC. Use existing TIPHON-Net for remote testing. • Interoperability between TIPHON systems and domains Operator specific tests. TIPHON system with PSTN ISDN ,GSM and other Mobile Systems, Country-specific features, etc. Test of specific features like TFO, etc. Vo-coder Tandeming • Interoperability of IP-Telephony services Inter domain services Test Infrastructure: –Interdomain QoS –Interdomain Security (Identification, Authentication, Authorization) –Different Domain Gatekeeper protocols; –Protocols between Gatekeeper and global Database; –Translation Routing of calls; –Global Numbering and Address translation –Charging, Billing Settlements • Field Trial User Feedback, Demonstration, Usability tests, Large number of users USAGE QUESTIONNAIRE FIRST RESULT The Usage Questionnaire was deferred to the next meeting. MANUFACTURER DECLARATION OF CONFORMITY (MDC) The ETSI secretariat has not yet reviewed the MDC proposal. NEW TIPHON-NET SITES • Adacel, Australia. VocalTec equipment. • Intelsat, Washington (US). VocalTec equipment. TIPHON-NET TESTS AND INTEROPERABILITY TESTING TD-40 (G. Koerbler, ETSI STF 114) contains a report of the tests that have been performed on TIPHON-Net. These tests use Ping Plotter (graphical trace-route program) and Pathchar (developed by V. Jacobson, allows any user to find the bandwidth, delay, average queue and loss rate of every hop between any Internet source and destination). TD- 40 provides no analysis of the data collected and there is no correlation between Ping Plotter and Pathchar results. TD-65 (M. Bias, KPN Research) provides suggestions for a test plan for TIPHON-Net. TD-28 (G. Kimchi, ETSI STF 114) proposes an Interoperability Event January 6-9, 1999. This was agreed. The interoperability test cases will cover mainly Scenario 1 (Box-interoperability). The STF shall prepare a test plan to present at the Tel Aviv (October) meeting. A draft will be put on the reflector at the beginning of October. At the Tel Aviv meeting, the test plan is planned to be approved, and companies will have to sign up for the Interoperability Event. The ETSI legal department will prepare a draft of an NDA for this event. When planning the event, cooperation with the IMTC implementers group will be sought. Provisions shall be made for remote sites to connect to this event. DTR/TIPHON–06001 The WG 6 deliverable DTR/TIPHON-06001, Verification and Demonstration Implementation (VDI); Implementors Handbook and Test Reports - Scenario 1, will be proposed for Project approval with some editorial changes at the next meeting. The results of the TIPHON-Net tests performed which are documented in TD-40 (see above) should be added to the deliverable. LIAISON ACTIVITIES The WG 6 chair will send a copy of recent deliverables to MSAF.

G. Kimchi (ETSI STF 114) will establish an informal liaison to the IMTC implementers group concerning interoperability events.

October 1998 Vol. 9.7 Copyright © CSR 1998 39 COMMUNICATIONS STANDARDS REVIEW – TELECOMMUNICATIONS REPORT OF TR-30.3, DATA COMMUNICATIONS EQUIPMENT EVALUATION AND NETWORK INTERFACES SEPTEMBER 9 – 10, 1998, RIVERSIDE, CA Editor’s note: TR-30.1 and TR-30.2 did not meet in September. TR-30.3/98-09-087, Assignment List from July 1998 was reviewed. S. Satchell (Henderson Labs) will setup the TR-30.3 FTP site (password required) with separate folders for each meeting. TR-30.3/98-09-103 is e-mail to S. Hoyler and B. Zedek-Connor (TIA) from J. Douglass (Oak Technology, TR- 30.3 chair) closing the Cellular Modem Testing projects PN-3251 (Cellular Network Transmission Model for Evaluating Modem Performance) and PN-3507 (Test Procedure for Evaluation of Cellular Modems). These projects were closed due to lack of support. LIAISON REPORTS The following e-mail liaisons were reviewed: • TR-30.3/98-09-098, from F. Daou (ADSL Forum Test and Interoperability Working Group Chair) requesting clarifications • TR-30.3/98-09-104, to D. Stuart (3Com) requesting a TR-30.3 Liaison with Q4/15 on xDSL • TR-30.3/98-09-105, to H.-E. Reiter (Ericsson), G. Young (British Telecom), and F. Daou (Genrad) requesting TR-30.3 Liaison with the ADSL Forum XDSL committee for testing • TR-30.3/98-09-106, to M. Humphrey (GlobeSpan) requesting TR-30.3 Liaison with the ATM forum on XDSL • TR-30.3/98-09-107, from C. Brownmiller (MCI) and draft letter from J. McDonaugh (Chairman, T1M1) requesting T1M1 Liaison with TR-30.3 on ADSL testing PN-3459, REVISING TSB-37A (T ELEPHONE NETWORK TRANSMISSION MODEL FOR EVALUATING MODEM PERFORMANCE) TR-30.3/98-09-100 is the cover sheet to submit SP-3459, Telephone Network Transmission Model for Evaluating Analog Modem Performance, as a USA contribution to SG16/Q10 (modem testing). It was presented at the US Study Group D meeting and was accepted. L. Brown (Motorola) will present the document at the SG16/Q10 meeting. B. Anders (3Com) will prepare a one-page summary of SP-3459 for the ITU meeting. TR-30.3/98-09-088 and TR-30.3/98-09-089 are SP-3459 ballot comments from R. Perez (Bellcore) and M. Pellegrini (TAS), respectively. Both were “yes” with multiple comments. TR-30.3/98-09-110©, SP-3459, Telephone Network Transmission Model for Evaluating Analog Modem Performance Draft 11, incorporates all the changes requested by R. Perez (Bellcore) and M. Pellegrini (TAS). TR-30.3 accepted the changes incorporated in SP-3459 Draft 11 and agreed that it should be sent out for default ballot (due to technical changes). PN-3509, REVISION OF TSB-38 (TEST PROCEDURES FOR EVALUATING MODEM PERFORMANCE) AND PN-3856, TEST PROCEDURES FOR EVALUATING PCM-MODEM PERFORMANCE TR-30.3/98-07-064 (S. Satchell, editor, Henderson Labs) is Draft 5 of PN-3509, Test Procedures for Evaluation of Two Wire Duplex Modems. TR-30.3/98-07-078© (S. Satchell, editor, Henderson Labs) is draft 3 of PN-3856, Test Procedures for Evaluation of PCM modems. TR-30.3 decided to combine PN-3509 and PN-3856 because: • PN-3509 is not urgently needed at this time • The test procedures for both projects are very similar • It would be better to have one test procedure for testing analog and PCM modems. Both projects will now fall under PN-3509 and will be released as TIA/EIA-3800 when completed. TR-30.3/98-09-109, Suggested Outline for Combined 3509 and 3856 modems (S. Satchell, Henderson Labs), is a strawman outline for the combined test procedures document. TR-30.3/98-09-094 (W. Henderson, Henderson Labs) contains sample test results for PN-3857/PN-3856.

Annex F, Data Reporting Format and Interpretation of Results, needs actual test data. S. Satchell (Henderson Labs) and B. Anders (3Com) agreed to provide test data using Draft 11. A system to run the full test suite will not be available until October. R. Perez (Bellcore) will check the normative references. A comment needs to be added to the Normative References on how to obtain the Normative Reference documents. J. Douglass (Oak Technology) will investigate this. Section 6.8 interoperability will be removed. New test files that are more representative of the type of files now being transferred (i.e., Web page data) will be used in the standard. The files should have varied compressibility such as ratios of 10:1 (fluffy), 1:1 (random), 2.5:1 (HTML) and 3:1 (text). These files should be long enough to prevent the V.42bis dictionary from memorizing the data. The files should also be representative of the data that would be transferred with on-line games, audio/ video and FTP downloads (PPP connections). J. Douglass (Oak Technology) will check on using a CD-ROM for the test files instead of floppy disks because the new test files will be much larger than the previous test files. TR-30.3/98-09-092 (S. Satchell, Henderson Labs) offers a new file transfer proposal. It proposes a different way to think about files to transfer. The major change is to abandon the concept of fixed-length files and instead transfer data until a time limit has passed. B. Anders (3Com), D. Bardes (ZD Labs), and J. Huang (Rockwell) will each download 20 pages of web page data so that it can be characterized. The block acknowledgment section will be modified to be representative of protocols that are used when transferring files over the Internet. Several types of block acknowledgment tests will be specified. D. Bardes (ZD Labs) will prepare a description of these test procedures. TR-30.3/98-09-090, Studies of 10 Base T performance as it relates to testing Ethernet-connected modems (LAN modem server) (S. Satchell, Henderson Labs), describes the results of several experiments. A test Ethernet network with three PCs and a 10 Base T hub was used as a test bed (aggregate capacity approximately 1100 kbytes/s). The three PCs supported six streams at 80 kbytes/s. Above this rate, performance degradation occurred caused by network collisions. An Annex on 10 Base T performance as it relates to testing Ethernet-connected modems will be added. PN-3857, TELEPHONE NETWORK TRANSMISSION MODEL FOR EVALUATING PCM MODEMS PERFORMANCE TR-30.3/98-09-101 is the cover sheet to submit PN-3857, North American Telephone Network Transmission Model for Evaluating PCM Modem Performance, as a USA contribution to SG16/Q10. It was presented at the US Study Group D meeting and was accepted. L. Brown (Motorola) will present the document at the SG16/Q10 meeting. G. Hillman (Motorola SPS) will prepare a one page summary of PN-3857. TR-30.3/98-09-108 (G. Hillman, editor, Motorola) is draft 8 of PN-3857, North American Telephone Network Transmission Model for Evaluating PCM Modem Performance, dated 8/13/98. TR-30.3 reviewed and resolved out- standing issues in PN-3857 Draft 8. G. Hillman (Motorola) will post draft 9 on the FTP site for one week for review and comment. Then PN-3857 will be submitted to TIA for ballot. TR-30.3/98-09-091, Test Reduction Revisited (S. Satchell, Henderson Labs), presents Structured Testing (originally contained in TR-30.3/98-07-061 but not presented at the previous meeting). It proposes to reduce testing from 320 connections to 109 connections by eliminating similar tests where practical. It also presents the revised table for the test reductions by systematic elimination. TR-30.3/98-09-094 (W. Henderson, Henderson Labs) contains graphs of V.90 connect data rate for specific PN- 3857 network loop types. TR-30.3/98-09-096 (R. Perez, Bellcore) is an analysis of non-loaded pairs from a 1983 Bellcore Loop Survey. It is discussed under PN-4254, below. TR-30.3/98-09-099 is E-mail from R. S. Gopalan (MultiTech) with tables of 3 dB PAD characteristics. TR-30.3/98-09-102, Email from R. S. Gopalan (MultiTech), requests clarification on some NSTL test results presented at the previous meeting. The following were submitted for information:

TR-30.3/98-09-093©, excerpts from T1.508-1992 Network Performance – Loss Plan for Evolving Digital Networks TR-30.3/98-09-097©, a copy of Recommendation G.715, Separate Performance Characteristics for the Encoding and Decoding Side of PCM Channels Applicable to 2-Wire Interfaces TR-30.3/98-09-111 (same as TR-30.1 ad hoc Norcross-97-09), Contribution to TR-30.1 Ad Hoc meeting in Norcross, GA, April 1997, PBX Attenuation PADs (B. Barnes, Inter-Tel and V. Demjanenko, VoCAL Technologies) The following comments, recommended changes and homework assignments were made: • It is possible to have 2 robbed-bits occur after the Central Office. • S. Satchell (Henderson Labs) will submit revised truncation tables for the Table 8: Universal Access Arrangement (UNAA/D$) and Table 9: Universal Network Access Arrangement (UNAA/ISDN). • G. Hillman (Motorola) and H. Hagen (Lucent) will provide TX and RX CODEC characteristics. • TR-30.3 decided to expand the scope to include V.34 modem testing when calling into a digitally connected host such as an ISP. All impairment combinations must be used when testing V.34 modems. PN-4254, TELEPHONE NETWORK TRANSMISSION MODEL FOR EVALUATION XDSL SYSTEMS AND PN-4255, TEST PROCEDURES FOR EVALUATING X DSL SYSTEM PERFORMANCE TR-30.3/98-09-096 (R. Perez, Bellcore) is an analysis of non-loaded pairs from a 1983 Bellcore Loop Survey. It notes that 76% of the pairs sampled were non-loaded. However, the raw data have been lost; the data presented here are from the final report. After reviewing this document, TR-30.3 had a brainstorming session where they defined the scope, the basic network model and the tasks that need to be worked on. The results of this brainstorming session are recorded in TR-30.3/98-09-112 (B. Anders (3Com). PN-4256, REVISION OF TIA/EIA-496-A, I NTERFACE BETWEEN DCE AND THE PSTN TR-30.3/98-09-095© (R. Perez, editor, Bellcore) is Draft 1 of PN-4256 (Revision of TIA-496A). PN-4256 contains many sections that are from other documents and are subject to change. TR-30.3 needs to decide whether text and drawings from these documents should be included or whether the appropriate document should be referenced instead. At a minimum, a note should be made to reference the source document for the most up-to-date information, and a list of these documents should be included in an abstract. H. Hagen (Lucent) will review PN-4256 with some of his associates, comment on the appropriateness of each section and on whether they still apply. After reviewing his comments at the next meeting, TR-30.3 will determine if the work on PN-4256 should be continued or if TIA/EIA-496-A should be rescinded. Jack Douglass, Oak Technology
