PURPOSE:To control a plurality of communication terminals with one communication control unit, by connecting the line to the communication control unit after selecting it in the order of arrival and priority from a plurality of communication terminals, and registering and recording the line number having transmission request from the communication terminals. CONSTITUTION:A communication control unit 38 performs data transmission by occupying the connection circuit until all the transmitting procedures for one message transfer are finished. On the other hand, with the command from the unit 38, the line selection section 23 selects lines in the order of priority and arrival from a number of communication lines and connects them to the unit 38. Further, the communication request waiting section 36 operates independently of the unit 38 and receives the transmission request only from the communication terminal and registers and records the line number having transmission request. Thus, a plurality of communication terminals can be controlled with one unit 38. |
