Disclosed are the multiplex communication system and the method therefore. A fault detection part of a duplex switching device detects it as generation of fault when recognizable signals are not detected from a connected line within a prescribed time. When the fault detection part detects the generation of fault in the present system line, the line switching part switches the lines from the present line to the standby line to perform communication between a terminal device and another terminal device therethrough. Also, the fault detection part notifies the generation of fault to the other duplex switching device after a prescribed switching protection time has passed from the time of the fault detected by the fault detection part, so the selection of the lines becomes consistent.

Multiplex communication system and method

In a transmitter, at least some of synchronization patterns in a signal having frame structure are inverted in a bit inverting circuit, and a plurality of channels of signals which include a signal having the inverted synchronization patterns are multiplexed and transmitted in a time-division manner. In a receiver, the time-division multiplexed channels are demultiplexed into individual channels. Then, frame synchronization is performed on the basis of the channel having the inverted synchronization patterns among the demultiplexed channels. With the frame synchronized channel as a reference, the remaining channels are identified. There is no need to provide a synchronization circuit in each channel, and the size of the system is not increased.

Time-division multiplexing transmission system

At a transmission side, an encoder,codes data of each channel and inserts a special character attributing to each channel. A character multiplex circuit,byte multiplex each channel for outputting. At a reception side, a character synchronization circuit,synchronized with a character by detecting the special character. A character demultiplex circuit,demultiplexes a signal by a character byte and obtains data of each channel. A channel identification circuit,identifies each channel by detecting the special character attributing to the channel without bit rotating for synchronization. A decoder,executes decoding without bit rotating and outputs a signal from a channel demultiplex circuit.

Channel multiplex demultiplex method and channel multiplex demultiplex unit

The present invention generates a reference signal including identification information based on a first coding method and generates data signals by a second coding method different from the first coding method. Next, it time division multiplexes signals by allocating the reference signal to a reference time slot and allocating data signals to time slots of which phase difference between the reference time slot is predetermined, and sends a multiplexed signal. In a receiver side, the reference time slot is detected based on identification information in a transmitted signal.
