Abstract
PURPOSE:To eliminate the use of a time slot for supervising and to consequently detect a trouble in its own station efficiently and without fail by supplying a supervising signal for supervising in its own station to the call channel in an idle condition. CONSTITUTION:In a time division multiplexing circuit 70, a supervising signal removed by a gate circuit 60 is time-division-multiplexed to the position of a time slot in a receiving IF signal corresponding to a call channel whose supervising signal is applied to time-division-multiplexing with a supervising signal multiplexing circuit 40 in accordance with call channel allotting information from a call channel control circuit 110. A trouble supervising circuit 100 supervises the presence and absence of the error of the supervising signal time- division-multiplexed to the output signal of a separating circuit 90 in accordance with the call channel allotting information from the call channel control circuit 110.
