Abstract

PURPOSE:To provide the proper information in accordance with the process of the party terminal, by transmitting the terminal power source cut-off information signal to the party terminal when the terminal power source under operation of both transmission and reception is cut off and then securing the reception of the information signal for the party terminal. CONSTITUTION:The constant voltage is supplied to input terminal 15 while both transmission and reception are being carried out, and the terminal power source cut-off pulse is supplied to input terminal 16. At the same time, the same level is set to the voltage to be applied to these two terminals in order to secure detection for the logic product of both input signals. As a result, the terminal power source cut-off signal transmitted to output terminal 18 is transmitted to the party terminal unit. On the other hand, each control signal transmitted from the party terminal unit is supplied to control signal extracting circuit 19 via input/output circuit 6 to identify the type of the control signal. Then terminal control circuit 20 operates based on the contents of the control signal. The terminal power source cut-off information signal sent from the party terminal unit is also detected in the same working procedure.
