PURPOSE:To shorten the time required for restart processing by transferring fault information to a processor for maintenance operation by providing a fault detecting means, which detects a fault including a switching processing fault, to every control processor, and also providing a means of instructing the start of an emergency program when detecting the switching processing fault by itself. CONSTITUTION:Channel networks 10, and 11-1n are equipped with subscriber circuits or trunks, and connected mutually through a junctor 2. A processor 7 for maintenance which controls the whole of switchboard is connected through a system bus 5 to processors 30, and 31-3n which exercise switching control over the channel networks 10, and 11-1n. This processor 7 is connected to fault detecting and fault processing program starting circuits 40, and 41-4n through a fault information transfer bus 6. Once the processors 30, and 31-3n detect faults of the channel networks 10, and 11-1n, emergency programs for the circuits 40, and 41-4n are started to transfer fault information to the processor 7, thus shortening restart processing time. |
