Summary

This ITU-T Recommendation defines the Protocol Implementation Conformance Statements (PICS) for protocols across the VB5 reference point as a supporting tool to ensure the interoperability of Access Networks and Service Nodes connected via interfaces at the VB5 reference points. It covers both the Real‑Time Management Coordination (RTMC) protocol which applies to the VB5.1 and the VB5.2 reference point and the Broadband Bearer Connection Control (B‑BCC) protocol which exclusively applies to the VB5.2 reference point. To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a telecommunication specification. Such a statement is called a Protocol Implementation Conformance Statement (PICS).
