    ORDERING INFORMATION

    ABSTRACT: This document replaces TR-NWT-001144.

    Issue 3 of GR-1144, OSSGR Section 6: Signaling, replaces Issue 2.

    GR-1144 contains the trunk and line signaling generic requirements for the operator services system. Some of these signaling
    requirements are identical to access tandem requirements; they are referenced in Sections 2 through 4. Sections 5 through 11 describe
    those requirements that are unique to the operator services system. Signaling requirements for interfaces with other network elements,
    such as the interface between the Core System and databases, are contained in GR-1149. Issue 3 of GR-1144 reflects the following
    changes:
    • Issue 3 describes Bearer Independent Call Control (BICC) signaling and the call scenarios in which BICC signaling is used.
      BICC signaling is used to establish, process, and release calls over an Asynchronous Transfer Mode (ATM) or Internet Protocol (IP)
      backbone network.

    • Issue 3 references the BICC generic requirements in GR-3100 for call scenarios in which BICC signaling is used, rather than
      ISUP signaling.

    • Issue 3 refers to logical traffic groups, rather than physical trunk groups, whenever BICC signaling is used.

    Issue 3 includes the Intercept codepoints and terminology that were adopted in ANSI T1 standards. To be consistent with ANSI
    standards, Issue 3 removes the conditional requirements associated with the signaling of the Local Service Provider Identifier (LSPI).

    GR-505, GR-690, GR-692, GR-1142, GR-1144, and GR-1147 replaced TA-TSY-001052.

    When using GR-1144, you may need to refer to GR-506, GR-317, GR-394, GR-532, GR-692, and/or GR-3100. You
