Abstract:
PURPOSE:To give no impression of a sudden disconnection of circuit to a receiver by providing the time limiting function at a transmitter station to monitor the communication time and informing a receiver station that the communication enable time is elapsed. CONSTITUTION:In a communication system where the communication time width is limited, the circuit connection may sometimes be cut forcibly during he transmission of the messages of a single unit. In such a case, the reason for the circuit disconnection is informed in the form of an auxiliary message to the station at the remote side in response to the stage of a communication sequence. A timer circuit 130 functions to secure the time (ta) needed for the transmission of said auxiliary message within the communication enable time T and to monitor the time limit for the discontinuation of transmission of the information on an original, i.e., the prescribed time (t). A transmitting station TX discontinues the transmission of the message when the time (t) is elapsed and then transmits the reason for the suspension of the transmission to a receiving station PX in the form of an auxiliary message in the remaining time (ta).
