Sistemi i telekomunikacionit dixhital celular (Faza 2+) (GSM); Kontrolli në-bandat e transkoduesve të largët dhe adaptuesit të vlerës, për kanalet e trafikut më gjysmë vlerë (GSM 08.61 versioni 7.2.2 Publikimi 1998)

Digital cellular telecommunications system (Phase 2+) (GSM); In-band control of remote transcoders and rate adaptors for half rate traffic channels (GSM 08.61 version 7.2.2 Release 1998)

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
GSM 08.60, both for the full and the half rate traffic channels (TCH/AFS and TCH/AHS).
The present document should be considered together with the GSM 06 series, GSM 04.21 (Rate Adaption on the
MS-BSS Interface) and GSM 08.20 (Rate Adaption on the BTS/MSC Interface).
