Common Channel Signaling Network Interface Specification (CCSNIS) Supporting Switched DS1/Switched Fractional DS1 Service Capability (SWF-DS1)

Document Number GR-1357
Issue Number 01
Issue Date May 1999
Replaces TR-NWT-001357 Issue01

    ABSTRACT: The Switched DS1/Switched Fractional DS1 (SWF-DS1) service capability allows customers to set up n x 64 kbps (2 less than or equal to n less than or equal to 24) calls from an Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) in real-time and in the same manner as any circuit-switched 64-kbps ISDN data call. SWF-DS1 is an extension of 64-kbps circuit-switched data calls and supports Unrestricted Digital Information (UDI) bearer capabilities at nx64 kbps. This Generic Requirements (GR) document provides information for interconnecting Local Exchange Carrier (LEC) Common Channel Signaling (CCS) networks with Interconnecting Networks (ICNs) to support internetwork SWF-DS1 service capability from an ISDN primary rate interface.

    This document replaces TR-NWT-001357, Issue 1, September 1993, but it does not contain any technical changes since that TR was published. It has been issued to conform to the Telcordia GR process.
