ETSI TS 148 061 Digital cellular telecommunications system (Phase 2+); In-band control of remote transcoders and rate adaptors for half rate traffic channels (3GPP TS 48.061 version 14.0.0 Release 14)
standard by European Telecommunications Standards Institute, 04/01/2017

Full Description
The present document describes the protocol between the Base Transceiver Station (BTS) and the remoteTranscoder/Rate Adaption Unit (TRAU) for speech and data on half rate traffic channel (TCH/H).For Half Rate speech and half rate data the protocol is specified for 8 kbit/s and 16 kbit/s submultiplexing scheme.
For Adaptive Multi-Rate speech the present document specifies the 8 kBit/s submultiplexing, both for the full and thehalf rate traffic channels (TCH/AFS and TCH/AHS). The specification for 16 kBit/s submultiplexing is given in Rec3GPP TS 48.060, both for the full and the half rate traffic channels (TCH/AFS and TCH/AHS).
The present document should be considered together with the 3GPP TS 46 series, 3GPP TS 44.021 (Rate Adaption onthe MS-BSS Interface) and 3GPP TS 48.020 (Rate Adaption on the BTS/MSC Interface).
