Here, the error code is an error level of the error code of the failure notification data received from the network device, which must always be notified to the operation and maintenance person, and includes specific contact number information. Is the contact information of the operation / maintenance person notified according to the error code of the failure notification data (number information of the portable terminal device (mobile phone, pager) carried by the operation / maintenance person, or possessed by the operation / maintenance person Personal computer address information). Further, in the present embodiment, specifically, for example, it is also possible to associate the operation and maintenance person with the failure notification data for each district and call the person in case of a failure in this district. And

FIG. 6 is a block diagram showing the internal configuration of the fault management unit 12 and the call management unit 13 shown in FIG. As shown in FIG. 5, the failure management unit 12 includes a notification data reception unit 121 and a notification data analysis unit 122, and the call management unit 13 includes a contact number acquisition unit 131 and a contact call unit 1
32.

In the failure management unit 12, first, the notification data receiving unit 121 receives the failure notification data from the communication control unit 11 shown in FIG. 4 and extracts an error code or the like of the received notification data. This is transmitted to the analysis unit 122. The notification data analysis unit 122 determines whether to make a call to a specific contact based on whether the received error code is registered in the failure management table 20. If it is determined that the received error code is registered, a call request is made to the call management unit 13 at the next stage. In the call management unit 13, the contact number acquisition unit 1
31 acquires the contact number registered in the contact number table 21 and requests the contact calling unit 132 to make a call. As a result, the contact calling unit 132 transmits the contact number to the failure notification control unit 14 shown in FIG.
