Abstract

PURPOSE:To secure the collective control for several receivers and thus realize the simultaneous transmission, by transmitting the tone signal from the transmission side in the circuit connection. CONSTITUTION:When the receiver is designated with operation of change-over switch 2 within control unit 1, control logic circuit 3 gives the indication to network control circuits 4a-4c to carry out the circuit connection. Circuits 4a-4c are connected to telephone circuits 5a-5c via the exchange. With connection of the circuits, the CED signals and then GI signals are sent from the reception side for a fixed time. Thus these signals are supplied to answer signal detecting circuits 7a- 7c. And with detection of the GI signals, circuit 3 transmits the tone signal sent from oscillating circuit 9 to circuits 5a-5c from hybrid circuits 6a-6c via circuits 4a-4c and with the time difference caused by the circuits. At the same time, FAX transmitter 11 is started to receive the GC signals. Meantime the transmission control is held at the reception side, and the GC signals are detected to transmit the GI signals to the transmission side. As a result, the phase signals are transmitted from the transmission side to start the FAX multiple-address transmission.
