Abstract
A facsimile and a facsimile system are connected to an inside bus of an ISDN (integrated services digital network). When trouble, such as no toner, jam, no paper or the like, has occurred in a recording unit of a first facsimile apparatus on the inside bus, the first facsimile apparatus issues an announcement of interruption onto the bus. A second facsimile apparatus on the above-described bus monitors a signal on the bus. When the second facsimile has detected the announcement of interruption, it performs substituting reception in place of the first facsimile apparatus. It is thereby possible to maintain the continuation of communication even if trouble has occurred during reception and recording.
