Abstract
A facsimile transmission apparatus includes a demodulator, an identifier, a control signal generator, a variable delay controller, and a multiplex transmission unit. The modulator demodulates a facsimile signal to output a demodulated signal. The identifier identifies the facsimile signal as one of a predetermined low-speed signal and a predetermined high-speed signal to output an identification signal. The control signal generator generates facsimile control channel (FCC) messages for controlling a protocol between facsimile apparatuses on the basis of the identification signal from the identifier. The variable delay controller performs variable delay control for the FCC messages from the control signal generator such that the FCC messages can be transmitted in a generation order. The multiplex transmission unit multiplexes each variably delayed FCC message from the variable delay controller with a demodulated signal, from the demodulator, corresponding to the variably delayed FCC message to transmit a multiplexed signal.
