PURPOSE:To enable a using maintenance processor to collect the information of the whole network processors by reading out processor information from a selected system control device, and transferring the information through a specified bus. CONSTITUTION:In the using maintenance processor group 1, system control devices 10A, 11A monitor the defective status of a using maintenance processor 10B or 11B for the self-system, control working and spare operation modes, and transmit/receive mutually processor information through a status contacting signal line 5. On the other hand, network processor groups 2-4 have similar constitution. The working system control device 10A e.g. in the using maintenance processor group 1 collects processor information from system control devices 20A-40A for self-systems in the network processor groups 2-4 through a bus 6A and also collect processor information from system control devices 11A-41A of other systems through a bypass bus 7. |
