ITU-T Q.2150.2

This Recommendation specifies the Signalling Transport Converter on SSCOP and SSCOPMCE. This Signalling Transport Converter on SSCOP (see ITU-T Q.2110 [2]) and SSCOPMCE (see ITU-T Q.2111 [3]) utilizes the Service Specific Connection Oriented Protocol for assured data transfer. This Signalling Transport Converter can be deployed on any protocol stack that supports SSCOP (e. g. AAL type 2 or AAL type 5) or SSCOPMCE (e. g. multiple AAL type 5 connections or IP with DIFFSERV). The sublayer structure, the PDU structures of the signalling transport converter sublayer, and the mechanisms for the provision of the generic signalling transport service are defined in depth. The intent of this Recommendation is to provide a protocol specification that can be used either in the B-ISDN ATM environment or a connectionless environment for the provision of a signalling transport service. In particular, this protocol provides a Generic Signalling Transport Service that is used by AAL type 2 and Bearer Independent Call Control (BICC) signalling protocols.
