Abstract

PURPOSE: To attain mutual communication between terminal equipments connected to the same digital subscriber line by using a loopback control section to apply loopback connection in one and the same channel and switching transmission/reception.
CONSTITUTION: In making a call from a terminal equipment 1 connected to one and the same digital subscriber line 3 to a terminal equipment 2, a loopback control section 4 applies a B1 channel to apply loopback connection, for example. Then the control is applied at the B1 channel to the terminal equipment 2. When the transmission is finished, the transmission of the B1 channel is controlled to the terminal equipment and the reception of the B1 channel is controlled to the terminal equipment 1. Thus, a transmission signal using the B1 channel from the terminal equipment 2 is received by the terminal equipment 1. Thus, the terminal equipments 1, 2 are subjected to mutual communication in semi-duplex by using the same channel.
