That is, when a transmitting side sends a CNG (Calling Tone) signal, the receiving side transmits a CED (Called Station Identification) signal. Thereafter, the transmitting side and the receiving side exchange DIS (Digital Identification Signal) and DCS (Digital Command Signal) of HDLC (High Level Data Link Control) format. Here, TSI represents a Transmitting Subscriber Identification and CSI represents a Called Subscriber Identification. Thereafter, the transmitting side transmits a training check (TPF) and the receiving side transmits a confirmation to receiver (CFR) to the transmitting side. Thereafter, the transmitting side transmits a message (MESSAGE), and when all messages are transmitted, sends an EOM (End of Message) indicating the end of the message. Accordingly, the reception side sends a message confirmation (MCF) indicating that the message has been received to the transmission side, thereby completing the transmission of the message.

On the other hand, the structure of the HDLC format mentioned above is as shown in FIG. Here, among the elements constituting the HDLC format, the FCF indicates the type of information exchanged between the transmitting side and the receiving side, and the FIF is a facsimile information field including information that is exchanged, and before actual print data is transmitted / received. All information on the transmitting side and the receiving side is placed in the FIF area and transmitted to the receiving side and the transmitting side, respectively.

At this time, the protocol exchanged between the transmitting side and the receiving side follows the provisions of FIG. 3, as mentioned above. That is, when a transmitting side sends a CNG (Calling Tone) signal, the receiving side transmits a CED (Called Station Identification) signal. Thereafter, the transmitting side and the receiving side exchange DIS (Digital Identification Signal) and DCS (Digital Command Signal) of HDLC (High Level Data Link Control) format. Here, TSI represents a Transmitting Subscriber Identification and CSI represents a Called Subscriber Identification. Thereafter, the transmitting side transmits a training check (TPF) and the receiving side transmits a confirmation to receiver (CFR) to the transmitting side. Thereafter, the transmitting side transmits a message (MESSAGE), and when all messages are transmitted, sends an EOM (End of Message) indicating the end of the message. Accordingly, the reception side sends a message confirmation (MCF) indicating that the message has been received to the transmission side, thereby completing the transmission of the message.
