PURPOSE:To attain a call through automatic dialing under the control of a data terminal device for a network controller for call mode of a telephone circuit, by incorporating a talking means instead of the device with no connection of a modulating/demodulating device. CONSTITUTION:In an automatic dial mode, a dialing action is fed to a telephone circuit 6 like the conventional procedure under the control of a data terminal device 4. When a network controller 1 detects an answer of the remote side, the circuit 6 is connected to a talking circuit 2 via a circuit protecting device 5. Thus a call is made possible with a head set 3, and at the same time a connection end signal is transmitted to the device 4. Receiving this signal, the device 4 completes the automatic dialing process and proceeds to the next process. A circuit restoration signal is received from the device 4 when the talking is over. Then the controller 1 releases the circuit 6 from the circuit 2. |
