摘要： 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.

摘要翻译： 因此，公开了多路复用通信系统和方法。 双工交换设备的故障检测部分在规定时间内从连接的线路检测到可识别的信号时，将其检测为故障的产生。 当故障检测部检测到本系统线路中的故障发生时，线路切换部将线路从当前线路切换到备用线路，从而进行终端装置与其他终端装置的通信。 此外，故障检测部在从故障检测部检测出的故障时刻经过规定的切换保护时间之后，向其他双工切换装置通知故障的生成，所以线的选择变得一致。
