In a circuit multiplex transmission system for transmitting speech/facsimile signals, a transmission circuit allocation control unit outputs a data transmission rate designation signal according to the load of the transmission circuit. A facsimile procedure operating unit operates a facsimile procedure, by reloading a control signal to be used for controlling the facsimile procedure or by selectively causing a training, which takes place prior to sending a message, to end in failure, in such a manner that a facsimile base band data transmission rate will be a rate designated by a transmission rate designation information. The result is that since the facsimile base band data transmission rate is controlled according to the load of the transmission circuit, it is possible to accommodate the same number of input telephone lines as that if every input signal is a speech signal.
