ABSTRACT:
A facsimile communication system makes a facsimile communication between a transmitting station and a receiving station. The transmitting station makes a call to the receiving station, detects a called station identification (CED) signal received from the receiving station, transmits a repeat (REP) signal to the receiving station when the called station identification (CED) signal is detected, detects whether or not the called station identification (CED) signal received from the receiving station stops within a predetermined time, and starts a facsimile transmission in conformance with a high-speed communication procedure when the stop of the called station identification (CED) signal is detected within the predetermined time. The high-speed communication procedure employs a protocol which requires less communication steps than a protocol of a standard communication procedure which is in conformance with CCITT Recommendations. The receiving station transmits the called station identification (CED) signal when the call is received from the transmitting station, detects the repeat (REP) signal received from the transmitting station, and stops the transmission of the called station identification (CED) signal when the repeat signal (REP) stops.
