Title: Communication line interruption instruction confirming system and communication line controller
Inventor: MIZUTANI YASUNAO
IPC: H04L29/08
Filed: 1988-04-14
Abstract: PURPOSE:To prevent interruption of a communication line due to misrecognition of a signal by allowing an interruption start station to send a 1st prescribed signal, allowing an opposite station side to reply it and to send a 2nd prescribed signal, allowing the interrupt start station receiving the 2nd signal to send a 3rd prescribed signal and confirming an interruption instruction of the communication line based on the 2nd and 3rd signals. CONSTITUTION:The system is so constituted that a 2nd communication line controller 120 receiving the 1st signal from a 1st communication line controller 110 sends the 2nd signal to reply the 1st signal and the 1st communication line controller 110 sends the 3rd signal to confirm a communication line interrupt instruction based on the reception of the 2nd and 3rd signals. That is, the interruption start station sends the 1st prescribed signal, an opposite station sends the 2nd signal in response to the 1st signal. The interruption start station confirms it that the opposite station receives the instruction by the reception of the 2nd signal and sends the 3rd signal to interrupt the communication line. Moreover, the opposite station confirms the communication line interrupt instruction by the reception of the 3rd signal to interrupt the communication line. Thus, the line interruption due to mis-recognition of signal is prevented.

Abstract: PURPOSE:To make unnecessary a monitor circuit and to simplify the title system by providing two monitoring time slots at a transmission frame, and respectively notifying monitor signals to express the conditions on upstream and downstream sides of the line during a video signal transmission to the downstream side and upstream side. CONSTITUTION:A terminal device 1A inserts a video signal DS converted into a digital signal into the transmission frame, and sends it to a line termination device 2A. Further, it inserts the monitor signal to express the condition of its own device to a first time slot T1, and sends it. A monitor signals SV is branched and extracted from a time slot 1 of the reception/transmission frame by the line termination device 1A. Consequently, the line termination station device 2A can know the action condition of the terminal device 1A to be a transmission source from the monitor signal SV. In the same way, to a time slot T2, the monitor signal to express the condition on the upstream side including the action condition of the line termination device 2A is inserted and sent. Consequently, without providing a separate line for the monitor signal transmission, the monitoring is attained by the simple constitution.
