Abstract

PURPOSE:To offer stable exchange function by supervising a terminal system device and a line scanning information line and fixing the line scanning information to the old information when a fault takes place so as to avoid a load of a central controller from being increased due to partial device fault. CONSTITUTION:After the line scanning information 4 detected from a line 2 is subject to multiplexing by a multilexer 3, the information is added with a normality confirming signal formed by a normality confirming signal generating circuit 7 at an insertion circuit 6 and fed to a channel system controller 9 through a channel system device 8 by line scanning information lines 16A, 16B.... The information is the line scanning information lines 16A, 16B subject to multiplex is checked for the normality by normality confirming signal check circuits 10A, 10B.... The line scanning information 4 transmitted from terminal system devices 1A, 1B... is written in line scanning information tentative storage circuits 11A, 11B in the timing signal generated by a line scanning information update pulse generating circuit 12 at the normal state periodically. If a fault is detected, the supply of the timing signal is stopped and the information in the storage circuits 11A, 11B... is preserved.

In conventional electronic exchanges, when line scanning information is multiplexed at the terminal equipment and transferred to the communication line control unit through one or more lines, the information is directly transmitted to the communication line control unit. It was sent to the call detection circuit or central processing unit for processing. Therefore, if a failure occurs in the terminal equipment that causes an abnormality in the line scanning information, or a failure in the line of the line scanning information, phenomena such as one-time call origination, one-time disconnection, and repeated call/disconnection will occur. This has the drawback of increasing the load on the central control unit despite partial equipment failure.
