Rapporteur:  JÄRVINEN, Kari
Descendant(s):  TS 46.062    


This TS gives the detailed requirements for the correct operation of the background acoustic noise evaluation, noise parameter encoding/decoding and comfort noise generation in Mobile Stations (MSs) and Base Station Systems (BSSs) during Discontinuous Transmission (DTX) on Enhanced Full Rate speech traffic channels.

The requirements described in this TS are mandatory for implementation in all GSM MSs capable of supporting the Enhanced Full Rate speech traffic channel.

The receiver requirements are mandatory for implementation in all GSM BSSs capable of supporting the Enhanced Full Rate speech traffic channel, the transmitter requirements only for those where downlink DTX will be used.

In case of discrepancy between the requirements described in this TS and the fixed point computational description of these requirements contained in TS 06.53, the description in TS 06.53 will prevail.
