MULTI-ADDRESS CALLING SYSTEM FOR FACSIMILE.

摘要

A multi-address calling office transmits simultaneously facsimile signals via a communication satellite. In this case, the multi-address calling office transmits the facsimile signals via at least one of a plurality of audio channels (ch1, ch2) of a satellite communication line. These facsimile signals are received by satellite communication receivers of terminal offices. At the terminal office, the received facsimile signal is sent to a switching control device, and in this device the facsimile signal and a control signal are switched and sent to a facsimile device. In the facsimile device, the control signal sent from the switching control device is used to produce a signal for operating means for switching the received facsimile signal. Thereby, the inputted facsimile signal is sent to a decision means in the facsimile device. The decision means detects an identification signal included in the facsimile signal received through the switching means. When the identification signal is verified, the facsimile device is permitted to receive the facsimile signals sent from the satellite communication line.
