ATIS 1000645.1995(S2018)

This standard provides 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 ATIS-1000111. These requirements cover the needs for signaling between network nodes and networks. This function is called Service Specification Coordination Function (SSCF) for signaling at the NNI. Formerly known as T1.645-1995(R2008).
