ABSTRACT:
A facsimile apparatus determines whether a frame to be transmitted is an image block or an error retransmission frame, and transmits a short training sequence or a long training sequence based on the results of the determination. The long training sequence is sent if a TCF signal is transmitted and the short training sequence is sent if the image block is transmitted. If the facsimile apparatus is on the receiving side, a training sequence in accordance with the frame from the transmitting side is received. After a carrier signal is detected, the apparatus then makes a transition to a mode for receiving the TCF signal or image block.
