である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the configuration of a line editing device that efficiently operates transmission lines and lines. In particular, the present invention provides a line blocking method for a line editing device that notifies cascade-connected transmission devices and exchanges of a line abnormality when a transmission line is disconnected, loses synchronization, or has other transmission line failures. In the line blocking method of a line editing device that performs normal operation, detects a transmission line failure, and generates a blockage signal, the output of the transmission line failure detection circuit provided in the transmission line interface receiver is sent to the transmission line interface receiver. The transmission line interface transmitter is connected to a fault signal bus that corresponds to all the included lines and is provided in parallel with the information and signaling path in the line setting section, and sends fault detection information via the fault signal path for each line. By inputting the input to the blockage signal generation circuit provided in the blockage signal generation circuit, the blockage signal generation function can be performed independently of the line editing operation, and furthermore, a blockage signal can be generated even when the transmission line interface receiver is removed. This is how it was done.

は回線ごとに異なっている。Usually, the pattern and sequence of blockage signals differ depending on the transmission equipment and exchanges connected via the transmission line, and depending on the line. Normally, multiple lines are multiplexed on one transmission line, and if a failure occurs on one transmission line, a blockage signal must be sent to all lines included in that transmission line. . Furthermore, these blockage signals differ depending on the line.

る装置に対し回線閉塞ができない欠点を有していた。Furthermore, in a station building where a line editing device is installed, the transmission line interface receiving section may be removed from the device due to partial repair, erroneous operation, or the like. In such a case, the prior art line blocking method has the disadvantage that the blocking signal generating circuit is also removed at the same time, so that the line cannot be blocked for the cascade-connected devices.
