A facsimile signal transmission system which satisfies the stipulation of the signal sending time and the stipulation of the signal time interval for enabling successful facsimile communication even if a detection delay or a sending delay occurs. In a facsimile signal transmission system for transmitting a digital command signal (DCS signal), an echo protect tone signal (EPT signal), a training signal, and a training check signal, if an IDLE message signal output from a transmission part at the end of the DCS signal is received in a reception party, a first timer operated for a first predetermined time is started. When the first predetermined time has elapsed, sending of the EPT signal to the reception facsimile terminal is started. A second timer operated for a second predetermined time is started at the same time as sending of the EPT signal is started. When the second predetermined time has elapsed, sending of the EPT signal is terminated. A third timer operated for a third predetermined time is started at the same time as sending of the EPT signal is terminated. When the third predetermined time has elapsed, sending of the training signal to the reception facsimile terminal is started.
