History
Specifies the Voice Activity Detector (VAD) to be used in the Discontinuous Transmission (DTX) as described in GSM EFR 06.31. It also specifies the test methods to be used to verify that a VAD complies with this ETS. The requirements are mandatory on any VAD to be used either in GSM Mobile Stations (MS)s or Base Station Systems (BSS)s that utilise the enhanced full-rate speech traffic channel.
