Abstract

PURPOSE:To facilitate to find out a troubled spot, and shorten a release time by outputting a trouble back signal, originating from the respective constituting part of a facsimile receiver equipment at the time of a trouble, while encoding it into a trouble code signal, from which the originating part of the trouble can be identified. CONSTITUTION:A trouble identification encoder 3 encodes the trouble back signal, originating at the time of the trouble of the respective part of the facsimile receiver equipment 2, into the trouble code signal, from which the troubled part can be identified, and outputs it. A trouble identification decoder 6 decodes the trouble code signal, from an HDLC reception circuit 5, and outputs the trouble back signal, classified for every constituting part of the facsimile receiver equipment. When a trouble information centralized supervising part 7 receives the trouble back signal, classified for every constituting part, from the trouble identification decoder 6, and the trouble back signal from the respective constituting part of the facsimile transmitter equipment 1, it displays the troubled constituting part. Thus, when the newspaper facsimile equipment is troubled during communication, what constituting part is troubled can be displayed.

[Problem that the invention seeks to solve]

In the conventional fault monitoring method described above, fault signals from each component of the paper transmission/reception device 2 are combined by a fault signal OR circuit 3a.
Since all types of fault occurrence signals are sent together, even if the fault information central monitoring unit 7a of the other party recognizes a fault, it cannot know which component of the receiving device has failed, and it is difficult to search for the fault location and restore it. The problem is that it takes a long time.

The purpose of the present invention is to
The object of the present invention is to provide a fault monitoring method that allows determining which component is at fault.
