ABSTRACT:
A multiplex transmission system according to the invention includes a transmitter and a receiver. The transmitter is provided with an idle frame inserting unit that inserts a specific idle frame different from an idle frame inserted into a surplus band of another signal into a surplus band of a predetermined signal and generates an internal signal, a multiplexing unit that multiplexes internal signals by time division and generates a multiplexed signal and a framing unit that transmits the multiplexed signal to a transmission line interface. The receiver is provided with a frame synchronizing unit that establishes synchronization of a transmission line interface and detects a multiplexed signal acquired by multiplexing internal signals acquired by converting signals by time division, a channel identifying unit that detects the specific idle frame in the multiplexed signal and specifies a position multiplexed by time division of each internal signal based upon a position of the specific idle frame, a demultiplexing unit that demultiplexes the internal signals, an idle frame extracting unit that removes the idle frame from the internal signal and a channel processing receiving unit that restores the internal signal from which the idle frame is extracted to a signal.
