ABSTRACT:
In transmission lines with a redundant structure having a switching control communication channel, the fault status of a transmission line, communication channel data, and transmission line selection status are inputted into a memory as addresses, and the transmission line is switched and the switching control data is transmitted using the output data. By doing this, when a fault occurs and the current transmission line is switched to a spare transmission line, the switching is performed in a short time without the processing load of the CPU being increased.
