Abstract

PURPOSE:To simplify the constitution of a facsimile communication network, etc., by using a common signal network as a control line by transferring terminal procedure via a bilateral transmission line and by transferring information over a communication channel connected only in one direction. CONSTITUTION:To originating terminals 1, 3... and terminating terminals 2, 4..., unilateral switching equipment 5 and 6 are connected, and to those originating and terminating terminals and switching equipment 5 and 6, control line network 7 is connected to constitute a message communication network. When information is sent from originating terminal 1 to terminating terminal 4, the terminal procedure concerning terminating terminal 4 is transferred between terminating terminal 4 and switching equipments 5 and 6 via control line network 7 by bilateral transfer. Next, after a unilateral communication channel from originating terminal 1 to terminating terminal 4 is connected, information is transferred from originating terminal 1 to terminating terminal 4 and the information is similarly transferred between originating terminals 1, 3... and terminating terminals 2 and 4, thereby simplifying the constitution of the facsimile communication network, etc.
