Common use of TELEPHONE NUMBER PORTABILITY ARRANGEMENTS Clause in Contracts

TELEPHONE NUMBER PORTABILITY ARRANGEMENTS. A. The Parties agree to provide interim Service Provider Number Portability (SPNP) on a reciprocal basis between their networks to enable their end user customers to utilize telephone numbers associated with an Exchange Service provided by one Party, in conjunction with an Exchange Service provided by the other Party, upon the coordinated or simultaneous termination of the first Exchange Service and activation of the second Exchange Service. The Parties shall provide reciprocal SPNP immediately upon execution of this Agreement via remote call forwarding (RCF) or Direct Inward Dialing (DID). SPNP shall operate as follows: A.1 An end user customer of Party A elects to become an end user customer of Party B. The end user customer elects to utilize the original telephone number(s) corresponding to the Exchange Service(s) it previously received from Party A, in conjunction with the Exchange Service(s) it will now receive from Party B. Upon receipt of a service order assigning the number to Party B, Party A will implement an arrangement whereby all calls to the original telephone number(s) will be forwarded to a new telephone number(s) designated by Party B within the same access where the original NXX code is used. Party A will route the forwarded traffic to Party B over the appropriate trunk groups, as if the call had originated on Party A's network. A.2 Party B will become the customer of record for the original Party A telephone numbers subject to the SPNP arrangements. Party A will provide Party B a single consolidated master billing statement for all collect, calling card, and third-number billed calls associated with those numbers with subaccount detail by retained number. Such billing statement shall be delivered via either electronic data transfer, daily magnetic tape, or monthly magnetic tape (for which option there shall be no charge). Party A shall provide to Party B the EMR detail records associated with the calls on the master billing statement. A.3 Party A will cancel line-based calling cards and will, as directed by Party B, update its Line Information Database (LIDB) listings for retained numbers, subject to RCF, and restrict or cancel calling cards associated with those forwarded numbers, as directed by Party B, subject to execution of an LIDB storage agreement in substantially the form attached hereto. A.4 Within two (2) business days of receiving notification from the end user customer, Party B shall notify Party A of the customer's termination of service with Party B and shall further notify Party A as to that customer's instructions regarding its telephone number(s). Party A will reinstate service to that customer, cancel the SPNP arrangements for that customer's telephone number(s), or redirect the SPNP arrangement pursuant to the customer's instructions at that time. B. SPNP-RCF is a telecommunications service whereby a call dialed to an SPNP-RCF equipped telephone number is automatically forwarded to an assigned seven or ten digit telephone number, within the local calling area as defined in Section A3 of the BellSouth General Subscriber Service Tariff. The forwarded-to-number is specified by BTI or BellSouth, as appropriate. Where technologically feasible, the forwarding party will provide identification of the originating telephone number, via SS7 signaling, to the receiving party. Neither party guarantees, however, identification of the originating telephone number to the SPNP-RCF end user. SPNP-RCF provides a single call path for the forwarding of no more than one simultaneous call to the receiving party's specified forwarded-to number. Additional call paths for the forwarding of multiple simultaneous calls are available on a per path basis and are in addition to the rate for SPNP-RCF service. C. The Parties shall provide RCF arrangements to each other at identical monthly rates. Recurring charges shall not exceed the actual cost of providing the service. There shall be no SPNP-RCF non-recurring charges. Until otherwise verified by reliable cost studies, actual cost for recurring charges are as stipulated in Attachment D hereto. The Parties agree that Article XXII of this Agreement shall apply to the rates, terms, and conditions for SPNP-RCF arrangements. D. SPNP-DID service provides trunk side access to end office switches for direct inward dialing to the other Party's premises equipment from the telecommunications network to lines associated with the other Party's switching equipment and must be provided on all trunks in a group arranged for inward service. A SPNP-DID trunk termination provided with SS7 signaling only, applies for each trunk voice grade equivalent. In addition, direct facilities are required from the end office where a ported number resides to the end office serving the ported end user customer. Transport mileage will be calculated as the airline distance between the end office where the number is ported and the POI using the V&H coordinate method. SPNP-DID must be established with a minimum configuration of two channels and one unassigned telephone member per switch, per arrangement for control purposes. Transport facilities arranged for SPNP-DID may not be mixed with any other type of trunk group, with no outgoing calls placed over said facilities. SPNP-DID will be provided only where such facilities are available and where the switching equipment of the ordering party is properly equipped. Where SPNP-DID service is required from more than one wire center or from separate trunk groups within the same wire centers such service provided from each wire center or each trunk group within the same wire center shall be considered a separate service. Only customer dialed sent paid calls will be completed to the first number of a SPNP-DID number group, however, there are no restrictions on calls completed to other numbers of a SPNP-DID number group. E. The Parties hereby agree to negotiate in good faith to establish the recurring and non-recurring charges, if any, for SPNP-DID. For this purpose BellSouth shall provide BTI with its relevant cost studies, subject to applicable non-disclosure obligations. The Parties agree that Article XXII of this Agreement shall apply to the rates, terms, and conditions of SPNP-DID arrangements. Until such permanent charges are established the Parties agree that the rates contained in Attachment E hereof (hereinafter the "Interim SPNP-DID Rates") will apply. F. Each Party is responsible for obtaining authorization from the end user for the handling of the disconnection of the end user's service, the provision of new local service and the provision of SPNP services. Each Party is responsible for coordinating the provision of service with the other to assure that its switch is capable of accepting SPNP ported traffic. Each Party is responsible for providing equipment and facilities that are compatible with the other's service parameters, interfaces, equipment, and facilities and is required to provide sufficient terminating facilities and services at the terminating end of an SPNP call to adequately handle all traffic to that location and is solely responsible to ensure that its facilities, equipment, and services do not interfere with or impair any facility, equipment, or service of the other Party or any of its end users. G. Each Party is responsible for providing an appropriate intercept announcement service for any telephone numbers subscribed to SPNP services for which it is not presently providing local exchange service or terminating to an end user Where either Party chooses to disconnect or terminate any SPNP service, that Party is responsible for designating the preferred standard type of announcement to be provided. H. Each Party will be the other Party's single point of contact for ad repair calls on behalf of each Party's end user. Each Party reserves the right to contact the other Party's customers if deemed necessary for maintenance purposes. I. The Parties will migrate from RCF or DID to Permanent Number Portability (PNP) as soon as practically possible, without interruption of service (to the degree possible) to their respective customers. J. Under either an SPNP or PNP arrangement, BTI and BellSouth will implement a process to coordinate Telephone Numbers Portability (TNP) cut-overs with Unbundled loop conversions (as described in Section IV of this Agreement). K. The quality of service of calls to ported numbers should be identical to the quality of service of the calls to non-ported numbers. L. If the FCC or a state commission issues regulations pursuant to 47 U.S.C. ss. 251 to require number portability in a manner or at rates different than that provided pursuant to this subsection, the Parties agree to revise this Agreement as necessary to fully comply with those requirements.
