    ABSTRACT: This document, Issue 5 of GR-1431, Common Channel Signaling Network Interface Specification (CCSNIS) Supporting Broadband
    Services
    , replaces Issue 4, November 1998.

    This document provides the Telcordia view of generic requirements for signaling interconnection of a typical client company network
    with interconnecting networks using Common Channel Signaling (CCS) to support internetwork Asynchronous Transfer Mode (ATM) broadband
    networking. The signaling is intended to allow Switched Virtual Connections (SVCs) to be established and released across a
    multiservice Broadband InterCarrier Interface (B-ICI). The B-ICI is set forth in GR-1115. GR-1115 provides information about the
    user and management planes for the B-ICI and, as such, is limited to support for Permanent Virtual Connections (PVCs). GR-1417
    provides Broadband Switching System (BSS) requirements for the signaling (control plane) information needed for establishing
    user-initiated SVCs in real time.

    This GR, on the other hand, describes the signaling (control plane) information that would be exchanged between a client company
    network and another network to support the establishment of user-initiated SVCs in real time.

    The intended users of this document are carriers whose networks interconnect with client company broadband networks for the purpose
    of supporting user-initiated SVCs across the network interface. This document describes the typical client company broadband network
    signaling as it appears at the network interface and focuses on meeting the needs of the interconnecting networks.

    This document describes procedures that affect the network interface when using the Broadband Integrated Services Digital Network
    User Part (BISUP) to establish and release ATM SVCs for calls that originate and terminate to an ATM-UNI and use an ATM internetwork
    interface. Related error and maintenance procedures are also included. The procedures relate to point-to-point and point-to-multipoint
    basic call, i.e., a call not involving supplementary service. Internetwork call control signaling is used to establish connections
    between client company BSSs that function as originating, intermediate, or terminating BSSs and suitably equipped interconnecting
    network BSSs.

    Procedures for 64 kbits/s-based narrowband circuit-mode services over ATM and interworking of these services with narrowband
    networks are supported over the signaling interface defined in this document.

    Procedures for switched frame relay service and interconnection with private networks are also supported over the signaling
    interface defined in this document.

    Issue 5 of GR-1431 reflects changes in GR-1417, Issue 5, and changes in the underlying standards and ATM Forum documents. Changes
    from Issue 4 of this document are indicated with change bars in the right margin. A summary of significant changes is included in
    Section 1.7.
