ITU-T Recommendations

The Q.1248.x family of ITU-T Recommendations defines the Intelligent Network (IN) Application Protocol (INAP) for IN Capability Set 4 (IN CS-4). This definition is based upon IN CS-3 ITU-T Q.1238 and ITU-T Q.1234 (2000) and upon the general rules for INAP provided in ITU-T Q.1208, and is consistent with the scope of IN CS-4 as defined in ITU-T Q.1241.Within the Q.124x series of ITU-T Recommendations, the Q.1248.x family of ITU-T Recommendation describes the protocol realizing the Q.1241 Distributed Functional Plane in a service and vendor implementation independent manner, as constrained by the capabilities of the embedded base of network technology. This provides the flexibility to allocate distributed functionality into multiple physical network configurations and to evolve IN from IN CS-4 to some future IN CS-N.This Recommendation belongs to the Q.1248.x family of ITU-T Recommendations for IN CS-4. It covers the SDF-SDF interface including the description of the aspects of the SDF and SDF Functional Entities which are relevant to this interface.This Recommendation includes an electronic attachment containing Annex A, ASN.1 definitions.
