摘要：A method for controlling a voice-controlled voice direction recognition unit fora digital telephone station, which can be connected to termination units having differenthybrid attenuations. The method prevents self-interruption in the transmission side dueto an excessively low hybrid attenuation. This is achieved by providing a counter unit thatidentifies the switching occurrences of the voice direction recognition per time unit and,when a predetermined number is exceeded, that causes the voice direction recognitionunit to connect an auxiliary attenuation element into every voice channel. The method canbe utilized in digital telephone stations whose termination units are located in anappertaining switching system.
