Abstract

PURPOSE:To improve the use efficiency of subscriber's lines by connecting a data terminal equipment having the receiving function of a subscriber of the other party to the transmission line of a data terminal equipment having the transmitting and receiving function and connecting a data terminal equipment of the subscriber of the other party to the reception line. CONSTITUTION:A subscriber's circuit 2a of a data terminal equipment 1a and a subscriber's circuit 2b of a data terminal equipment 1b of the other party are connected by a transmission line 5a, and the circuit 2a and a subscriber's circuit 2c of a data terminal equipment 1c of the other party having the transmitting function are connected by a reception line 5b. A common controller 7 sets a call path 5a in a switch network 6 through circuits 2a and 2b for the purpose of transmitting data from the equipment 1a to the equipment 1b. If data is transmitted from the equipment 1c to the equipment 1a during data transmission from the equipment 1a to the equipment 1b, the controller 7 sets a call path 5b. Thus, the equipment 1a not only transmits data to the equipment but also receives data from the equipment 1c to improve the use efficiency of subscribers.
