ETSI ETSI TS 148 061 V7.0.0 (2007-10) 6 3GPP TS 48.061 version 7.0.0 Release 7 1 Scope The present document describes the protocol between the Base Transceiver Station (BTS) and the remote Transcoder/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 the half rate traffic channels (TCH/AFS and TCH/AHS). The specification for 16 kBit/s submultiplexing is given in Rec 3GPP TS 48.060, both for the full and the half rate traffic channels (TCH/AFS and TCH/AHS). The prese
