Telephony device comprising a base station and at least a subscriber unit, subscriber unit for such a telephony device and method used in such a telephony device

摘要

A communication device communicates with a station and includes a receiver which receives speech signal frames from the station. The speech signal frames have speech signals. The communication device further includes a counter and an attenuation circuit. The counter counts the number of bad frames of the received speech signal frames. The attenuation circuit diminishes the amplitude of the speech signals when the count of the counter is higher than one indicating more than one bad frame is received. The station is either connected to a switched network or is a satellite station.
