Abstract

PURPOSE:To obtain a backup means when the state of a main channel has a failure, by using facsimile terminals connected to multiplex communication lines to instruction lines subjected to the main channel line of the multiplex communication line through switching. CONSTITUTION:Instruction line hardsets 8 and facsimile terminals 51 are connected to instruction line terminals of a plurality of communication devices 6 connected with multiplex ratio lines 1 via switching devices 7. The switching devices 7 are normally selected to the handsets 8 to constitute the substantial instruction line system, and the facsimile terminals are connected to the instruction lines by operating the devices 7 manually or with the instruction signal as required. Thus, fascimile transmission using the instruction lines can be made between arbitrary stations, and after a communication device 6 is in failure or the state of the multiplex ratio lines are deteriorated, the instruction lines can also be used for backup use for the facsimile transmission.
