ABSTRACT: Issue 5 of GR-1417, Broadband Switching System SS7 Generic Requirements replaces Issue 4, November 1998.

GR-1417 provides the Telcordia view of generic requirements for the use of the Signaling System No. 7 (SS7) protocol for signaling between Broadband Switching Systems (BSSs) to support Switched Virtual Connections (SVCs). Specifically, this document describes procedures for using the Broadband ISDN User Part (BISUP) of SS7 to establish and release ATM switched virtual connections. This document represents current views based, in part, on existing and evolving standards related to B-ISDN. This document is also aligned with the ATM Forum Broadband Inter-Carrier Interface (B-ICI) Specification, Version 2.0 and Addendum thereto. This document, wherever possible, points to specific requirements already listed in other Telcordia requirements documents.

The generic requirements given in this document cover switch functions and the messages, procedures, and parameters applicable to an interswitch interface that, in the view of Telcordia, are necessary to provide B-ISDN services across multiple BSSs. Included are procedures to support calls involving switched virtual connections between BSSs, including calls between client company networks and other Interconnecting Networks (ICNs). These ICNs include Interexchange Carriers (IXCs), International Carriers (INCs), and other Local Exchange Carriers (LECs), including Independent Local Exchange Carriers (ILECs). The procedures relate to B-ISDN point-to-point and point-to-multipoint single-connection basic calls. No supplementary services procedures are described. This document also provides requirements for supporting 64 kbit/s-based narrowband ISDN circuit-mode services and interworking with narrowband networks using ISUP. This document provides requirements for BISUP signaling using a quasi-associated CCS network, as well as requirements for BISUP signaling directly over ATM transport in the CCS associated mode. In addition, this document provides high level requirements related to interworking with private networks.

Issue 5 of GR-1417 includes major changes in Sections 7, 8, 9, Appendixes A, B, C, D and H. For more detailed information regarding these changes, refer to Section 1.5.
