Abstract
This invention proposes to eliminate the limitation that the reception data, assigned to a subchannel, cannot be re-assigned to another subchannel in the transmission. For this purpose, in a configuration of the present invention, the transmission information, formed by multiplexing information of plural kinds in a multiplexing unit, is transmitted to a line control unit which is connected to a communication line and serves to transmit and receive information to and from different locations, while the reception information received from the communication line is received by the line control unit and separated in a demultiplexing unit into the information of respective kinds, and at least one is selected by an entire control unit from thus separated plural information and is turned back to the multiplexing unit through a turn-back bus.
