ABSTRACT:
A multiplex audio signal from an exchange apparatus is demultiplexed by a first multiplexer/demultiplexer into demultiplexed signals that are supplied to a first switch circuit which switches between transmission paths to apply the demultiplexed signals to a plurality of audio coding circuits. Certain output signals from the audio coding circuits are supplied to a second switch circuit, time-division-multiplexed, and applied to the first switch circuit. The multiplexed signal is outputted from the first switch circuit for transmission in a given time slot over a radio communication path.
