Abstract

PURPOSE:To contain a data terminal with an automatic response function in a digital switchboard by connecting the power-supply switch of the data terminal or by receiving a disconnection instructing signal, and providing the data terminal connector which controls the power supply. CONSTITUTION:When the power supply of a data terminal 32 does not turn on, a data terminal 31 transmits a power-supply connection demand signal of the opposite terminal on the communication route. A data terminal connector 22 detects the power-supply connection demand signal using a data-terminal power- supply control signal detection circuit 75, and turns on the power-supply of the data terminal by controlling a data-terminal interface circuit 62. When the data communication completes, the data terminal 31 transmits the power-supply disconnection demand signal of the opposite terminal. The device 22 detects the power-supply disconnection demand signal by the circuit 75, and disconnects the power supply of the data terminal by controlling the circuit 62.
