Testing Services offered under this section of the tariff are optional and subject to rates and charges as set forth in 13.3.4(C) following. Other testing services provided by the Telephone Company in association with Access Services are furnished at no additional charge. These other testing services are described in 6.1.6 and 7.1.7 preceding.

Testing services are normally provided by Telephone Company personnel at Telephone Company locations. However, provisions are made in (A)(5), (B)(1) and (B)(2) following for a customer to request Telephone Company personnel to perform testing services at the customer's premises.

The offering of Testing Services under this section of the tariff is made subject to the availability of the necessary qualified personnel and test equipment at the various test locations mentioned in (A), (B) and (C) following:

(A) Switched Access Service

Testing Services for Switched Access are comprised of (a) tests which are performed during the installation of a Switched Access Service, and (b) tests which are performed after acceptance of such access services by a customer, i.e., in-service tests. These in-service tests may be further divided into two broad categories of tests: scheduled and nonscheduled.

Scheduled tests are those tests performed by the Telephone Company on a regular basis, e.g., monthly, which result in the measurement of Switched Access Service. Scheduled tests may be done on an automatic basis (no Telephone Company or customer technicians involved), on a cooperative basis (Telephone Company technician(s) involved at Telephone Company office(s) and customer technician(s) involved at customer's premises), or a manual basis (Telephone Company technician(s) involved at Telephone Company office(s) and at customer's premises).

Nonscheduled tests are performed by the Telephone Company "on demand", which result in the measurement of Switched Access Services. Nonscheduled tests may involve Telephone Company technicians at Telephone Company offices and at the customer's premises.

16.1.1 General

Ameritech Central Office Interconnection (ACOI) provides a customer with a

Transmission Node; i.e., a Central Office Space in the Central Office equipment area and associated power and environmental conditioning to locate certain fiber optic facilities and Transmission Equipment as described in Section 16.1.2(A)(2)

following. The Telephone Company provides a customer a Transmission Node only to connect to certain Telephone Company provided Switched Access

services and/or Special Access services via Ameritech Cross-Connection Service for Interconnection (ACCSI) described in Section 16.4, following. Central

Office space provided under ACOI cannot be a point of termination for any other service than those listed in Section 16.4.

ACOI is available in Telephone Central Offices specified in Section 16.6. Additional offices will be filed, for inclusion in Section 16.6., within 45 days of

Telephone Company receipt of a bona fide request from customers for ACOI within a Central Office to be effective upon 45 days' notice.

ACOI must be made in accordance with the provisions specified in Technical

Reference Publications AM-TR-EEN-000011 (Ameritech Installation Administrative and Workmanship Requirements) and AM-TR-EEN-000015 (Ameritech Central Office Equipment and Engineering Requirements). (N)

16.1.2 Rules and Regulations

(A) ACOI will be provided subject to the following provisions: (Sxy)

(1) ACOI arrangements are available on a first-come, first-served basis subject to the availability of space and facilities in each Central Office. Establishment of the order in which Central Office Space will be given to customers will be dependent upon the date and time that the Telephone Company receives a completed ACOI application. No partially completed applications will be accepted. In the event that the customer desires ACOI in an office where ACOI is unavailable due to space limitations, the Telephone Company's receipt of a completed ACOI application will establish the priority in which space will be allocated to customers in the event space becomes available at a later date.

Customers must request ACOI through their Telephone Company point of contact established upon initial request for service. The point of contact will provide the customer ACOI application documents through which they must convey their requirements for space and associated support requirements such as power and environmental conditioning, and any other matters of a special nature pertaining to occupancy.

Following receipt of an ACOI application, the Telephone Company will verify that there is sufficient Central Office Space to meet each request for Central Office Space contained in the customer’s ACOI application. The Telephone Company will notify the customer in writing whether there is sufficient Central Office Space available for each request for Central Office Space.

Upon receiving the written notification of the availability of Central Office Space from the Telephone Company, the customer must send written verification that they still require each Central Office Space requested on the customer’s ACOI application for which space is available. This written notification is the customer’s firm order for ACOI service for each Central Office Space requested. (Sxy)

The customer will be required to pay fifty percent (50%) of the Central (Nx) Office Build Out (COBO) charge when they place their firm order for ACOI service, twenty-five percent (25%) of the COBO charge half way between the firm order date and the ACOI service due date and the remaining twenty-five percent (25%) of the COBO charge when the COBO work is completed.

Customers wishing to convert their current Ameritech Virtual Optical (Nx) Interconnection Service to ACOI, which previously purchased the ACOI service offered before December 31, 1994, will not be charged the ACOI nonrecurring charges when the following conditions are met:

(a) The customer requests ACOI service in the same space occupied by the customer’s previous ACOI service, (b) The ACOI space previously occupied is still suitable for ACOI service, (c) No work needs to be performed to prepare the space for ACOI, (d) The customer previously paid the ACOI nonrecurring charges, and (e) The customer was not refunded previously paid ACOI nonrecurring charges. (Nx) (MxSy) When the Telephone Company receives the customer’s firm order for Central Office Space, it will conduct a Pre-Construction Survey for each customer request for Central Office Space to identify all modifications and work required to provide the customer with the requested space. After the Pre-Construction Survey the customer

must make itself available for a Telephone Company - customer meeting. (MxSy)

(Sxy) After the Telephone Company - customer meeting, the customer will

receive a written proposal for the provisioning of ACOI service from the Telephone Company. This proposal will detail the associated requirements and the tariffed charges required to meet the customer’s specific ACOI request and the expected service date. The customer shall acknowledge acceptance of the tariff charges in this written proposal by signing it and returning a copy to the Telephone Company. (Sxy) (Dx)

18.1 Miscellaneous Services

18.1.1 Signaling System 7 (SS7) Gateway Signaling

(A) General Description

SS7 Gateway Signaling provides for the switching and transport of SS7 messages by the Telephone Company’s SS7 network and routes these

messages to the global title address or the signaling point code address

based on the translation performed at the Signal Transfer Point (STP)

The provision of SS7 Gateway Signaling on an interLATA basis by the

Telephone Company is limited to SS7 signaling used in connection with the provision of telephone exchange services or exchange access

services by a local exchange carrier and to common carriers offering

interLATA services at any location within the area in which the Telephone Company provides telephone exchange services or exchange access

service.

(B) Provisioning

SS7 Gateway Signaling is subject to the screening and routing information contained in the Telephone Company’s STPs.

When the Telephone Company’s STP routes messages for the purpose of establishing trunk voice paths between switching machines, call set-up

times may be adversely affected when the customer employs

Intermediate Access Tandems in its network. The Telephone Company makes no warranties with respect to call set-up times when multiple

STPs are involved or when the signaling traffic is exchanged between

two non-Telephone Company signaling points. This provision will be applied uniformly to all customers including Telephone Company affiliates. (Nx)

(1) Determining the MARC

The customer’s initial Minimum Annual Revenue Commitment (MARC) is calculated based on the total of the previous three (3) months recurring billing for qualified access services, multiplied by four (4).

The MARC is calculated as follows:

(Recurring Billing(1)Amount for Previous Three (3) Months) X 4 = MARC(2)

(2) Re-establishing the MARC

The MARC may be increased semi-annually, effective with the contract anniversary date. The MARC may be increased but never decreased. The minimum increase of the MARC is 5%. The revised MARC represents the customer’s MVP revenue commitment for the remainder of the MVP five (5) year agreement upon which (D) discounts will be calculated. (D)

(N) The following illustrates sample MARC re-establishment dates: A customer MVP Agreement effective date and associated initial MARC are established on October 1, 2000. The customer cannot re-establish the MARC until

October 1, 2001. If the customer does not re-establish the MARC on October 1, 2001, the next time the customer can re-establish the MARC is April 1, 2002. The following dates are the only other days upon which the MARC may be re- established:

October 1, 2002 April 1, 2004 April 1, 2003 October 1, 2004 October 1, 2003 April 1, 2005

The effective date of the revised MARC is the corresponding MARC re-

establishment date. (N)

The MVP commitment discount is applied monthly, for those months where the criteria is met. If the customer does not receive the monthly commitment discount, it may still receive the discount, if it is in compliance with Section 19.3 (x) by the contract anniversary date, through the true-up process described in 19.3(H).

Example 1: A customer is in Year 1 of its MVP agreement. Its MARC is established at $12 million, per the guidelines in 19.3(C)(1), preceding. The customer achieves a qualified monthly billing of $1.07 million and has an Access Ratio of 97.53%.

The customer’s MVP Commitment Discount is equal to $90,000, calculated as follows:

Annual MARC = $12M Monthly MARC = $12M / 12 months = $1M Monthly MARC achievement = $1.07M MVP Commitment Discount = 9% MVP Monthly Credit = $1.0M * .09 = $90,000

(5) Nonrecurring Installation Charge Waivers For all Access Service Requests (ASR) that have an Application Date (APP Date) (N) on or after the effective date of the MVP Agreement, all nonrecurring initial (N) installation charges associated with Term Pricing Plans of three (3) years or longer, with the exception of expedited and special construction charges (as set forth in (T) Sections 5.2.2 and 5.1.3 preceding), for the qualified access services described in (T)

19.2, preceding, will be waived for the duration of a customer’s MVP Agreement, as long as the circuit remains in service for at least three years or as long as the terms and conditions of the underlying term plans are met. The nonrecurring initial (N) installation charges do not include subsequent changes and/ or moves. (N) Nonrecurring charges for optional features and function associated with the initial (N) installation of a circuit will be waived. Nonrecurring charges for the subsequent (N) addition of optional features and functions (after the initial installation) will not be (N) waived. If the underlying service is terminated before its term agreement expires, the customer will be billed the nonrecurring charges associated with the underlying tariff when the circuit is disconnected or the service is terminated. In the event MVP

is terminated before the terms and conditions of the underlying term plan are met, the nonrecurring charges previously waived under MVP will be billed to the customer. (F) Renewals Prior to expiration of an MVP Agreement, an MVP customer may renew its agreement for an additional five (5) year term without incurring a termination liability, as contained in 19.3(J), following. All renewals must occur no later than three (3) months before the expiration date of the original MVP agreement. The MVP Commitment Discount for the MVP Agreement Renewal will be 14% for the five (5) years of the renewal agreement. The MARC for the new MVP Agreement Renewal will be the existing Annual MARC of the final year of the previous MVP Agreement. Only one renewal is permitted per MVP Agreement. Upon expiration of an MVP Agreement or an MVP renewal, and if an MVP tariff remains in effect and is not grandfathered, a new MVP Agreement may be established with a new MARC developed per the provisions contained in 19.3(C)(1), preceding.

MVP-SLA parameters are established for a twelve month interval commencing with the MVP Agreement date. The service performance level parameters for each of these three (3) services shall address: (a) On-Time Provisioning (OTP) – Calculated by dividing the number of customer requests for new service and rearrangements of existing service that were missed for Telephone Company reasons by the total number of new service requests and rearrangements of existing service completed during the (x) reporting period. The date used to determine whether or not the service (x) request was missed is the Service Conformation Date provided on the Firm (x) Order Confirmation (FOC).

(b) Failure Frequency (FF) – Represented as an annualized percent of the MVP customer’s total access circuit failures. Calculated by dividing the total number of Telephone Company circuit failures during the reporting period by

the cumulative number of embedded circuits for the same period and multiplying the result by 12. Only “found trouble” reporting codes are considered to be failures. “Found trouble” reporting codes are report codes (x) CC, CO, FAC, STN and SVB.

(c) Time to Restore (TTR)- Measure of outage duration calculated by dividing the total number of measured troubles that are less than or equal to 3 hours in

the reporting period by total number of troubles in the same reporting period. All measured troubles codes are included in this calculation. These are CC, (x) CO, FAC, NTF, STN, SVB and TOK.

Service performance in each of the service categories will be averaged for each MVP customer by quarter and by year throughout the life of the MVP agreement. These service averages will then be used in the following Level 1 Service Assurance calculation to determine whether or not the 1% Level 1 (T) Service Quality Assurance credit is applicable to the MVP subscriber for a (T) given year.

(b) Calculation

At the conclusion of each MVP Agreement year, the 12-month averages for

each measured service component will be compared to its corresponding target in Table 1.0. For those service components that meet or exceed this target, a point value will be assigned for each quarter and for the end of year. (N) DS1 services will be valued at three points, Base Rate services at 2 points, (N) and VG services at one point. For service performance below the (N) benchmark, no points will be awarded. If, during a quarter, an MVP-SLA (N) qualified service is not eligible due to the failure to meet one of the minimum (N) requirements as identified in 19.3 (G) (2) (a) the corresponding point value for (N) that particular qualified service will be assigned for that quarter.(1) As illustrated in Table 2.0, the maximum possible annual score (quarterly and annual totals combined) is 96 points.

(b) Calculation

Level 2 Service Quality Assurance is applicable beginning with results from the (T) third MVP Agreement year and only comes into play in the event the Telephone (T) Company fails to perform at the previously described Level 1 standard (i.e., total (T) combined quarterly and end-of-year average results less than 104 out of 144 possible points for any given year). In such an event, the MVP Agreement year-end average service measures for DS1 will also be compared to the targets set out in Table 3.0. Should any of these measures be worse than their corresponding Level 2 (T) targets, the additional 1% Level 2 Service Quality Assurance credit will be applied for the year preceding. (H) MVP Annual True-up Amount (MATA) An annual true-up calculation will be performed after each anniversary of the MVP Agreement. The MVP Annual True-up Amount (MATA) provides an opportunity to receive monthly discounts that were not received because the monthly MARC was not met and/or the Access Service Ratio was not greater than or equal to 95%. The customer receives the MATA only if at the time of the annual true-up process the customer is in compliance with all of the terms of the MVP Agreement as stated in 19.3(B), preceding. The MATA is calculated as follows: Total Annual Total of Monthly Discount MATA = MVP Commitment - Credits Received Discount Amount for the Year The customer will receive a true-up credit from the Company in the amount of the MATA, if the customer qualifies as stated above.

Its MARC is established at $12 million per the guidelines in 19.3(C)(1), preceding and the customer has an Access Service Ratio of 95.7%, then: The Total Annual MVP Commitment Discount Amount = $12 million * 9% = $1.08 million. The customer exceeded the annual MARC of $12 million, but because it did not meet the monthly MARC in one month of the previous year, the total credits received for year 1 of the MVP Agreement = 11 months * the monthly credit of $.09M = $.99M. Then the customer will receive a MATA credit equal to $1.08M - $.99M = $.09M Example 2: A customer is at the end of year 2 of its MVP Agreement. Its MARC is established at $12 million per the guidelines in 19.3(C)(1), preceding and the customer has an Access Service Ratio of 95.7%, then: The Total Annual MVP Commitment Discount Amount = $12 million * 11% = $1.32 million. The customer exceeded the annual MARC of $12 million, but because it did not meet the monthly MARC in one month of the previous year and did not have an Access Service Ratio of greater than or equal to 95% in another month, the total credits received for year 2 of the MVP Agreement = 10 months * the monthly credit of $.11M = $1.1M. Then the customer will receive a MATA credit equal to $1.32M - $1.1M = $.22M

Any annual true-up credits or adjustments will be applied to the customer’s bill within sixty (60) days following the anniversary of the MVP Agreement. If the customer fails to achieve MARC or has an Access Service Ratio less than 95% on (T) the anniversary date of the MVP Agreement, the customer must choose one of the options contained in 19.3(I), following.

Example: A customer requests termination of an MVP Agreement 3.5 years into the agreement. The customer met the MARC four of the preceding six months. This customer’s Year 3 MARC is $10.6M and the Year 3 monthly MARC is $883,333.33. The termination liability is:

Credits paid the preceding 6 months = ($883,333.33 * 13%)*4 = $459,333.33

Plus

Remaining MARC for Year 3 $5.3M X 12.5% = $662,500 Year 4 MARC $10.6M X 12.5% = $1,325,000 Year 5 MARC $10.6M X 12.5% = $1,325,000

The customer will pay a Termination Liability of $3,771,833.33

(2) Termination of MVP Agreement Due to Rate Reductions

If qualified MVP access tariff rates are reduced a cumulative total of 30% from the (x) contract effective date rates, either party may discontinue MVP, upon sixty (60) (x) days written notice without incurring MVP termination liability.

In order to determine if the 30% reduction threshold has been met or exceeded, the rate reduction percentage change for each qualified MVP access rate element is calculated, then the weighted average of those percentages (based on product volumes) is used as the threshold percentage.

Transfers $12M to new customer (assignee or transferee) in keeping with the 60 day provi sion in Section 19.3(L)(1)(a),(b), or (c).

Current customer remaining revenue does not qualify for MVP. Current customer (assignor or transferor) pays termination liability as follows:

(Current MARC $20M) – ($12M included or assumed by new customer) = $8M. Termination liability will apply on $8M as described in Section 19.3(J).

(3) In keeping with existing terms and conditions, if the current MVP customer (assignor or transferor) can qualify for MVP and can achieve its existing MARC with the remaining qualified access revenues, no adjustment to the MARC will be made. (N) If (1), (2), or (3) are not applicable, termination liability charges, as described in Section 19.3(J), will apply.

(A) General Description

(1) Description

When a new customer (assignee or transferee) chooses to assume the remaining term of a transferred MVP customer’s MARC under a separate term agreement as described in Section 19.3(L), the new customer must follow the terms and conditions as described in Section 19.3.1.

The MARC will be calculated as follows:

(a) MARC calculation:

Amount of transferred MARC commitment, divided by twelve (12) months, equals monthly MARC commitment for the remaining term of the term agreement.

Example:

$12M MARC transfer / 12 months = $1M monthly MARC commitment

(B) Application of Discounts

Discounts will apply to assigned or transferred qualified access services listed in Section 19.2. MVP Commitment discounts will begin the first full month following the effective date of the assignment or transfer.

Discounts will apply to the monthly MARC based on the year in which the MVP MARC commitment is transferred or assigned as long as the customer meets all the obligations, terms and conditions addressed in Section 19.3.1(D) and (E):

Yr 1 Yr 2 Yr. 3 Yr. 4 Yr. 5 Year Transfer Transfer Transfer Transfer Transfer % discount 9% 11% 12% 13% 14%

Example:

Customer assumes a transferred MVP MARC commitment in Year 3 of an existing

term agreement. A discount of 12% will be applied monthly during term year 3 as

long as all terms and conditions are met. The subsequent years applicable discount schedule will be based on the anniversary dates associated with the original (transferred) MVP Term Agreement through the end of the transferred MVP Term Agreement period. (N)

20. Internet Transport Access Service (ITAS) (N)

20.1 Service Description

Internet Transport Access Service (ITAS) is a switched based, data transport service that aggregates and hands off traffic using a one way data connection to the customer. The customer is defined as an entity providing dial access service via a data switch. ITAS will support calls from analog modem users or ISDN Basic Rate Interface (BRI) lines. ITAS is provisioned through the use of end office (EO) switching, and transport from the Telephone Company’s EO. Dial-Up user data is transmitted to the customer via

dedicated EO port groups. Routing of end user traffic to the customer’s data switch requires Signaling System 7 (SS7) call setup. The customer may purchase SS7 access from Section 6 (Switched Access Service). The customer must also purchase a Direct Trunked Transport (DTT) and an Entrance Facility separately from Section 6 (Switched Access Service). In addition, the customer may need to purchase multiplexing from Section 6 (Switched Access Service). Customers who require physical or virtual collocation must purchase interconnection cross connects from Section 16 (Expanded Interconnection

Service).

ITAS is available in Telephone Company central offices (CO) that support 64kbp clear channel capability (CCC). These locations are listed in the National Exchange Carrier Association, Inc. (NECA) Tariff F.C.C. No.4.

20.2 Service Components

ITAS consists of the following service components as described below.

A. Telephone Numbers

ITAS is accessed by end users dialing telephone numbers dedicated to the customer’s service and within their designated calling scope. All telephone numbers will be routed to Telephone Company provided dedicated switch ports. There will be a minimum of one telephone number per connected EO.

B. Access Port Groups

Allows end users, located within a specific local exchange area, dial access to the customer. The access port consists of local switching, and a dedicated EO switch port to the customer and will be provisioned with Telephone Company Provided Telephone Numbers (TPTN). A maximum of three trunk

groups will be allowed to be provisioned against any one port group. Telephone numbers may be purchased from Section 20.5 (Rates and Charges).

When the traffic for an end user exceeds the capacity for a DS1 to any given end office, the Telephone Company reserves the right to require the customer to connect directly to the EO identified by the Telephone Company’s. If the customer refuses to connect to the identified EO the customer will be

given a thirty day written notice to connect to the identified EO. If at the end of the thirty days the customer has not connected to the identified EO its ITAS will be terminated.

21.5.2.18 Vintage Rates

(A) General Regulations

Term pricing plan vintage rates are those rates that apply to existing services provided under a term plan in the event the Telephone Company initiates a rate increase. Vintage rates as set forth following are classified as vintage because the Telephone Company ensures that rates provided under a term plan will not be increased by the Telephone Company above the term plan rate in effect at the beginning of the customer’s term plan.

Vintage term pricing plan rates associated with services and/or MSA’s which have not been approved for Phase II pricing flexibility are found in Section 7.5. These vintage rates are applicable in the above mentioned rate increase situations for term plans of services and/or within MSA’s with no pricing flexibility approval at beginning of the term plan.

Term plans associated with approved services/MSA’s at the outset of the contract will employ Section 21 for vintage rates in regards to rate increase situations. (N)
