答しディジタル命令信号DO8を受信側へ送出する。In facsimile communication, before sending and receiving facsimile image information, a procedure (protocol) is essential for mutually communicating and confirming the terminal capabilities and functions possessed by opposing facsimile machines on the sending and receiving sides. For example, CCITT Recommendation T.30 stipulates that message transmission after call setup be performed using a binary control procedure or a tonal control procedure. Among these, the binary control procedure is mainly used for high-speed facsimile machines (group 3 (
As shown in Figure 2, after a telephone conversation, when the receiving side (called station) presses the communication start button, the called station identification signal C
ED and further sends a digital identification signal DIS to the transmitting side (calling station) to notify that the station is based on the system specified in KCCITT Recommendation T, 30, and the transmitting side is identified by the digital identification signal DIS. In response to the standard function provided, a digital command signal DO8 is sent to the receiving side.

る。The transmitting side sends out a training check signal TCP for the receiving side to perform training. When the receiving station receives the TCP signal and completes all pre-message procedures, it notifies the transmitting side that it may start transmitting the message (image information) using the reception preparation confirmation signal CFH. From this point K, the transmitting side sends out image information PIX, and when the message transmission for one page of the original is completed, it sends out a procedure end signal EOP.

Each binary control signal described above is assigned a code on a byte basis.

であった。Conventionally, it has been impossible to perform voice communication, which is a method of communicating using the entire voice band, not only while transmitting and receiving facsimile image information, but also while executing the above-mentioned protocol. For example, the standard G3 protocol shown in FIG. 2 requires about 11 seconds for the start protocol and about 3 seconds for the end protocol, and voice communication was not possible even during execution of this protocol.
