PURPOSE:To obtain a telephone reservation identifying signal by the procedure interrupting (PIS) signal from the transmission side after receiving the called station identifying (CED) or group identifying (GI) signal from the receiving side in the telephone reservation from the transmitter of a medium-speed facsimile. CONSTITUTION:In case of telephone reservation in a transmission block 1, when a telephone reservation identifying circuit 6 is operated by the key operation, the CED or GI signal is transmitted from a CED and GI signal transmitting circuit 15 of a receiving block 2 and is detected by a CED and GI detecting circuit 5 of the transmission block 1 to open a reservation AND circuit 11, and the PIS signal from a PIS output circuit 7 is transmitted. This PIS signal is detected by a PIS receiving circuit 18 of the receiving block 2 and is combined with the output of a CED and GI display circuit 17 to open a telephone reservation AND circuit 21, and thus a telephone reservation signal is obtained in a telephone reservation output terminal 21. |
