A modem apparatus comprising a transmitter 30 for transmitting data from a modem to another modem and a receiver 40 for receiving data from the other modem to one modem. When a high signal among the low signals is input, a predetermined voltage is output to operate the transmitter 30, and the receiver 40 is shut off, and when a low signal is input, a predetermined voltage is output to operate the receiver 40. In addition, the transmitter 30 includes a power supply circuit 20 between the control means 10 and the transmitter 30 and the receiver 40 so as to block.

따라서, 상기 제어부(10)에서 제공하는 모드 선택신호(200)에 따라 전원회로부(20)에서 송신 및 수신부(30)(40)로 소정의 전압을 인가하여 현재 사용하지 않는 부분은 동작차단하고, 현재 사용하는 부분만 자동으로 동작하게 하여 전력 소모를 최소화한 것이다.Therefore, according to the mode selection signal 200 provided by the control unit 10, the power circuit unit 20 applies a predetermined voltage to the transmission and reception unit 30 and 40 to block the operation that is not currently used. Only the parts that are currently used are automatically operated to minimize power consumption.
