ITU-T Q.2220

ITU-T Recs Q.711, Q.712, Q.713, Q.714, Q.715 and Q.716 define the services of the Signalling Connection Control Part (SCCP). The SCCP provides, above the signalling transport network (or networks) connection-oriented, connectionless, routing, and management services. ITU-T Rec. Q.711 defines the services provided; ITU-T Rec. Q.714 describes the procedures performed by the SCCP. These procedures make use of the messages and information elements defined in ITU-T Rec. Q.712, whose formatting and coding aspects are specified in ITU-T Rec. Q.713. ITU-T Rec. Q.715 is a guide for the SCCP and ITU-T Rec. Q.716 defines SCCP performance. This Recommendation defines the Transport-Independent Signalling Connection Control Part (TI-SCCP), which consists of a modification to SCCP that allows it to operate on various signalling transport networks. In addition to the MTP3 and MTP3b networks, TI-SCCP can operate on SSCOP and SSCOPMCE based networks as well as on IP-networks by utilizing the transport protocol defined in RFCs 2960 and 3309. The independence of the particular signalling transport technology is achieved by basing the TI-SCCP on the Generic Signalling Transport Service (ITU-T Rec. Q.2150.0) and deploying one of the Signalling Transport Converters specified in ITU-T Recs Q.2150.1, Q.2150.2, or Q.2150.3.
