Then, when specific subscriber's units are selected and respond, response discrimination circuit 12 of the center unit detects this response to start center number information transmission circuit 13, and circuit 13 sends pre-signals and transmits information of the center number. In the subscriber's unit, this information is received by center number information receiving circuit 3 and is stored in storage circuit 4. It is unneccessary to decode the stored number by each subscriber, and each subscriber is connected to the center by operation of switch S1.
