PURPOSE:To attain information transfer while using the optimum time without any special processing and provision of any special line by transferring only generation of an instant fault to a maintenance-centralized center if a fault takes place in a station controlled by the maintenance centralized station and storing the detailed data relating to the said fault in a specific address area of a memory. CONSTITUTION:When a controller 1 detects a fault in the own station, the controller 1 classifies the fault depending on the importance, a fault transfer device 5 is started, a dial pulse is sent via a general talking trunk 4, the fault class is connected to the maintenance-centralized center, where the fault is displayed. Further, the maintenance data relating to the fault is stored in a predetermined address of a storage device 2. The maintenance-centralized center places discrimination depending on the transferred fault class and when further detailed data is required, the subscriber number of the faulty station is dialed, a call is incoming to a subscriber line 6 to set a line with the maintenance- centralized center. |
