This document specifies the bearer data transport and bearer control protocols used between MGWs within the CS core network across the Nb Interface. It assumes the implementation of the split of the call control and the bearer transport and control, as specified in TS 23.205 with BICC-based Nc, and in TS 23.231 with SIP-I based Nc.

For BICC-based Nc, the User Plane protocol that uses this bearer data transport (Nb UP) is described in TS 29.415. The transport format for the Nb interface with IP transport can optionally allow RTP multiplexing. Note that the present document does not preclude an implementation of a combined MSC Server and MGW.
