た。In a conventional single-wire switch, when line scanning information is multiplexed at the terminal system and transferred to the channel control system through one or more lines, the information is directly transferred to the channel control system. The call detection circuit within the system was sent to the central control unit for processing. Therefore, in the event of a terminal device failure that causes an abnormality in line scanning information, or a line scanning information line failure, this may cause phenomena such as two simultaneous calls, repeated disconnections, or partial device failure. Despite the failure, it had the disadvantage of increasing the load on the central control unit.

である。In order to achieve the above object, the line scanning information processing system according to the present invention is a line scanning information processing system in an electronic exchange in which line scanning information is multiplexed in a terminal system device and transferred to a communication path control system device for processing. A normality confirmation signal is added to each line scanning information output to one or more lines, and a normality confirmation signal inspection circuit is installed at the receiving end to detect faults in terminal equipment or line scanning information lines. In this case, the line scanning information is fixed to a specific signal.
