PURPOSE:To transmit a control signal transmitted to an exchange by a terminal device via an out-channel into other terminal devices by providing a means transmitting the control signal transmitted via the out-channel in a subchannel through an in-channel of other subchannel belonging to the same channel. CONSTITUTION:A selecting circuit 201 selects any of communication information of the subchannel A transmitted via the in-channel Ai from a terminal device by the command from a signal controller 5 and the control signal of the subchannel B transmitted via the out-channel Bo, transmits it to a transmission circuit 202, and a selecting circuit 204 selects any of the communication information of the subchannel B transmitted via the in-channel Bi from the termina device 1 based on the command from the signal controller 5 and the control signal of the subchannel A transmitted via the out-channel Ao and transmits it to a transmission circuit 205. A separating circuit 211 transmits the communicating information transmitted from a receiving circuit 210 to the terminal device 1 by the command of the signal controller 5. |
