PURPOSE:To simplify the switching of system constitution, by performing the switching of call processor with an operation and maintenance processor directly, through the provision of a multiprocessor supervision and controller, between the call processor and the operation and maintenance processor. CONSTITUTION:A system bus 6 which makes normal monitoring and control of a control system is provided between a call processor CP1 controlling each network of a multi-processor system and an operation and maintenance processor OMP3 making control and maintenance among the CP1. In addition to the bus 6, a control bus 10 is connected between the CP1 and the OMP3, and this bus 10 is provided with a multi-processor supervision and controller MPC9. This MPC9 is used as calling means, the switching of the CP1 is made by the OMP3 directly, then the switching of system constitution is executed simply and surely. |
