Scope, purpose, and application

The intent of this standard is to provide a function that is part of the ATM Adaptation Layer for the support of signaling (SAAL) at the Network Node Interface (NNI) of the B-ISDN. This function is used to map the service of the Service Specific Connection Oriented Protocol (SSCOP) of the AAL to the requirements of an SAAL user at the NNI as defined in ANSI T1.111. These requirements cover the needs for signaling between network nodes and networks. This function is called Service Specific Coordination Function (SSCF) for signaling at the NNI.

This standard specifies the Service Specific Coordination Function for support of signaling at the NNI (SSCF at the NNI). It covers the aspects of the SSCF of the complete AAL structure for signaling applications at the NNI defined in ANSI T1.636, and describes the interactions with the level 3 protocol entity for network node signaling defined in ANSI T1.111, layer management defined in ITU-T Recommendation Q.2144, and the Service Specific Connection Oriented Protocol, ANSI T1.637.

This standard is applicable to equipment to be attached to a B-ISDN Network Node Interface when B-ISDN inter-nodal signaling is to be supported. Although this standard makes reference to MTP-3 (ANSI T1.111) to identify user requirements, this SSCF may be utilized by other protocol entities which are able to rely on the SSCF services specified in this standard.

 This standard is based on ITU-T Recommendation Q.2140. Differences with respect to ITU-T Recommendation Q.2140 are described in annex E.
