PROBLEM TO BE SOLVED: To correctly transmit fault information to a manager managing faults on the occurrence of detection of faults in the exchange and to reduce the communication cost in this case. SOLUTION: On the occurrence of an important fault in an exchange 1A or the like, a time management section 14 controls a dialer 15 to change an external notice destination (that is, an external management device 14 or a pocket pager 42) for each set time to inform the occurrence of the important fault. As a result, the important fault is surely transmitted to the notice destination and then the fault is quickly troubleshooted. Furthermore, since a manager is in the vicinity of an in-network management, equipment 2 does not inform fault information via a public network 3 for a time zone not requiring the information of the fault information via the public network 3 or in the case of a usual fault not requiring a quick response, the communication cost is reduced.
