ETSI ETSI ES 283 024 V1.1.4 (2007-07) 6 1 Scope The present document defines the profile of the Gateway Control Protocol (ITU-T Recommendation H.248.1 3), for controlling Trunking Media Gateways (TM

23、GW) for both the PSTN/ISDN Emulation and IMS Core Subsytems. Thus the scope of this Profile is a subset of the 3GPP profile for the Mn interface defined in TS 129 332 2. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the presen
