7.18 The Facilities Signaling Point of Interconnection (FSPOI) for each link shall be
located at a cross-connect element, such as a DSX-1. These are located in each of
BellSouth 38 LATAs. If the serving GSTP is not in the same LATA as the FSPOI,
BellSouth will extend the link to the GSTP at its own expense. There shall be a DS1
or higher rate transport interface at each of the FSPOIs. Each signaling link shall
appear as a DS0, or DS1 channel within the DS1 or higher rate interface. BellSouth
shall offer DS1 rate signaling links for interconnecting TC SYTEMS local switching
systems or STPs with BellSouth GSTPs as soon as these become approved ANSI
standards and available capabilities of BellSouth GSTPs.
7.19 The Parties agree to implement intraoffice diversity for the signaling links so that no
single failure of intraoffice facilities or equipment shall cause the failure of any two
links in a layer connecting to one of BellSouth GSTPs.
7.20 BellSouth shall set message screening parameters to block or accept messages from
TC SYTEMS local or tandem switching systems destined to any signaling point in
the BellSouth SS7 network with which the TC SYTEMS switching system has a
legitimate signaling relation.
7.21 BellSouth Switched Access (SWA) 8XX Toll Free Dialing Ten Digit Screening
Service
7.21.1 The BellSouth SWA 8XX Toll Free Dialing Ten Digit Screening Service database
(8XX SCP Database) is a SCP that contains customer record information and the
functionality to provide call-handling instructions for 8XX calls. The 8XX SCP IN
software stores data downloaded from the national SMS/8XX database and provides
the routing instructions in response to queries from the SSP or tandem. The
BellSouth SWA 8XX Toll Free Dialing Ten Digit Screening Service (8XX TFD
Service) utilizes the 8XX SCP Database to provide identification and routing of the
8XX calls, based on the ten digits dialed. At TC SYTEMS’s option, 8XX TFD
Service is provided with or without POTS number delivery, dialing number delivery,
and other optional complex features as selected by TC SYTEMS.
7.21.2 The 8XX SCP Database is designated to receive and respond to queries using the
ANSI Specification of Signaling System Seven (SS7) protocol.
8 Trunk Forecasting and Servicing Requirements
8.1 The Parties agree to provide non-binding trunk forecast information to each other
twice a year pursuant to the provisions of this Agreement. Each forecast provided
under this Section shall be deemed “Confidential Information” under the General
Terms and Conditions of this Agreement. The semi-annual forecasts shall include:
8.2 Yearly forecasted quantities of trunks for traffic that originates on or transits its
network to the other network for three (current and plus 1 and plus 2) years where
possible;
