Abstract

PURPOSE:To make the monitor of operation for a channel memory and a memory corresponding to a subscriber in real time, by making coincidence between a subscriber address and another address read out from the channel memory, and comparing this output with a channel usage signal read out from the memory corresponding to the subscriber. CONSTITUTION:When a subscriber makes a call, a selection indicating signal is inputted to a channel memory 2, and the detection of a vacant channel is made through the scanning of the memory 2. After the detection, a subscriber address is written in corresponding to the channel and the usage of channel is written in a memory 1 corresponding to the subscriber. On the other hand, the subscriber ad- dress written in the channel memory 2 is read out in channel period. A coincidence circuit 3 requests the coincidence between the subscriber address and the subscriber address output of the channel memory 2. A comparison circuit 4 compares the state of channel usage bit of the memory 1 with the output state of the coincidence circuit 3, the memory 1 or 2 is detected for failure to instruct clearning of the memory.
