In the above-mentioned conventional technology, in a multiprocessor exchange consisting of a plurality of communication processing processors that realize communication processing functions and a mask communication processing processor that realizes system operation functions, when the system is started up, the communication processing processor is connected to the mask communication processing processor. The system initialization information is read out only from the active auxiliary storage device, and the process of transferring it to each processor is performed.Since the multiprocessor exchange system is started up from the iC, the entire exchange There is a problem that it takes too much time to start up the system.An object of the present invention is to reduce the time required to start up a multiprocessor exchange system.

[Means for Solving the Problems J] The above purpose is to connect the current auxiliary storage device and the backup auxiliary storage device [fX'' to the mask communication processing processor in advance, and to connect the current auxiliary storage device and the backup auxiliary storage device [fX] to the mask communication processing processor, and to The system initialization M times information is read out from the device to the memory 0 of the mask 41M processing processor, and the next transfer information for system initialization is read out from the preliminary memory to the memory 1 of the master communication processor at the same time. After that, first, the memo 90 is read out to the IC, and the initial setting information is simultaneously initialized in each processor in a circular process. Next, read out the initial setting information to the first side of memory in the same way.
c/? ! r processors.

Above 1, current auxiliary memory 1 Please read out the initial setting information to be transferred to each processor from the auxiliary storage device at the same time as the reading from the current auxiliary storage device. It is possible to shorten the startup time of a multiprocessor exchange system.

[Effect]

System initialization of the master communication processor is performed by reading out system initialization information from the current auxiliary storage device connected to the master communication processing processor. When the current auxiliary memory K+[ is in failure, the system reads out the initial HA setting information from the backup auxiliary storage and performs the system initialization of the mask communication processor, so the current auxiliary memory + i and the backup auxiliary storage are read out. By reading out system initial setting information from
Hokage? 'Y will not affect you.
