ITU-T Recommendations

This Recommendation defines the intelligent network application protocol for the support of the capabilities required by the CS-1 target services over the CS-1 interfaces (SSF-SCF, SCF-SDF and SCF-SRF) as defined in Recommendation Q.1211. It defines some of the possible protocol stack scenarios, the operations which flow between the entities and the procedures to be followed at each functional entity.Revisions to this Recommendation provide: details on operations procedures, details on services assumed from underlying protocol layers, extensions to ensure applicability in multiple administration networks, a new SCF-SDF interface for data administration and acquisition based upon the X.500-Series of Recommendations, and detailed error handling procedures. The intent of these revisions is to facilitate consistent multi-vendor implementations in multiple networks.Associated standardization work is contained in all the Q.1200-Series Recommendations (Intelligent network).
