摘要
A plurality of signal processors and a plurality of spare signal processors are respectively formed of a card so as to be disposed on substrates different from each other. A type of signal processing is performed for a plurality of digital signals of a primary group digital signal in the signal processors, and a primary group processed digital signal obtained from a plurality of processed digital signals is sent out. When a fault occurs in a specific signal processor, the specific signal processor of a fault condition is detected in a system monitoring and controlling unit, the specific signal processor is switched for one spare signal processor of a non-fault condition by taking off the specific signal processor and inserting the spare signal processor.
