PURPOSE:To simplify the whole constitution of an transmission controller without increasing the load of a central processor, by providing a transmission interface processor between a terminal device and the central processor and adding a means to discriminate a transmitter from a receiver. CONSTITUTION:A transmission interface processor is provided between a terminal device and a central processor, and a means is added to discriminate a transmitter from a receiver. For instance, a message sent to a receiver A12 from a terminal device A11 is discriminated by a transmission interface processor B1 on the basis of the codes written to the prescribed columns of the message and showing both the transmitter and the receiver. The discriminated message is then transmitted through a prescribed route. At the same time, the message to a receiver host C from a terminal device A12 is discrimintated by the processor B1 and then transmitted. The message which is transmitted from a terminal device A18 and then recived at a terminal device A22 belonging to a group that controls the transmission interface processor is transmitted once to the host C and then delivered via a transmission interface processor B2. |
