PURPOSE:To simplify the interface signal and the constitution of equipments by connecting a transmission section including a control section and a modulation section by 3 sets of wires and connecting a reception section including a control section and a demodulation section by 3 sets of wires. CONSTITUTION:The control section 1a and the transmission section 3a are connected by three wires a, b and e and the control section 1a and the reception section 4a are connected by three wires c, d and f. Further, the control section 1a is provided with a P/S conversion circuit 1x having a function converting a signal into a 16-bit setting information serial form. Every time a synchronizing signal is sent from the transmission section 3a, the control section 1a drives the P/S converting circuit 1x to use the signal line (a) and to send once 16-bit information serially and the transmission section 3a sends the received 16-bit information to an opposite MODEM repetitively eight times.
