ABSTRACT:
A fault monitoring system having a reduced cost and management load. The system includes a voice/facsimile response unit composed of a controller and a network interface. The controller has a management server and a fault monitoring section to achieve the voice/facsimile response function. It dials through the network interface a monitored line which is entered on a monitored subject information table at a calling time intervals. If the dialing call is established to the called party, then the monitored line is regarded as normal. If the called party is busy, the dialing is iterated. If the frequency of the redialings exceeds a predetermined number, this is regarded as a fault occurring at the called party. When notifying a maintenance person of the fault by voice, a voice message is edited for the notification. When notifying the maintenance person of the fault by telefax, text data is edited. The mutual fault monitoring between the voice/facsimile response units makes it possible to obviate a dedicated computer and telecommunications channels for monitoring.
