Summary

This Recommendation belongs to the DSS2 family of ITU-T Recommendations and specifies extensions to Recommendation Q.2931 to specify the additional DSS2 protocol elements (messages, information elements, procedures and functions) required to support the separated control (establishment, modification, clearing) of bearers associated to a call controlled independently by means of a separated call control protocol. The separated call control protocol may be either the generic functional protocol-based separated call control protocol defined in Recommendation Q.2981 or the Q.2931-based separated call control protocol defined in Recommendation Q.2982.
