(PICS)Proforma Abstract
Specifies the Signalling Transport Converter on MTP3 and MTP3b. This Signalling Transport Converter on MTP utilizes the services offered by the Message Transfer Part of Signalling System No. 7. 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 in the ISDN and B-ISDN 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.
