Rapporteur:  Mr. Andersen, Niels Peter Skov
Antecedent:  TS 08.61    

This TS 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 this TS 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 TS 48.060, both for the full and the half rate traffic channels (TCH/AFS and TCH/AHS).

This TS should be considered together with the TS 46 series, TS 44.021 (Rate Adaption on the MS BSS Interface) and TS 48.020 (Rate Adaption on the BTS/MSC Interface).
