PURPOSE: To connect a device or an equipment with a transmission channel by providing an intermediate register for a control signal and data. CONSTITUTION: A coupling circuit 5 is provided with a detecting circuit, and this circuit is constituted of the RC circuit of a transformer 10, diode 11, resistance 12, and capacitor 13. The presence or absence of an RF pulse transmitted through a power distribution trunk line 2 can be detected by this detecting circuit. A signal transmitted through a channel 2 can be used in a binary signal form by an invertor 14 connected between the circuits 12 and 13. The circuit 5 is constituted so that the time constant of the RC circuit can be set between the frequencies of the RF signal and the frequencies of the power distribution trunk line. A processing circuit 6 is connected between the circuits 5 and a circuit 7, and the circuit 6 is used for processing transmitted bits, confirming that a reception signal is adapted to a set specification, or forming a transmission signal. The circuit 7 is provided with a memory 8 programmed by a microprocessor. Thus, a device or an equipment can be connected with a transmission channel.
