間欠障害で閉塞された回線を自動復旧して回線の有効利
用を図ることができるようにしたものである。The present invention aims at effectively utilizing the lines by automatically restoring lines blocked due to intermittent failures in a line maintenance device that connects exchanges by automatically performing periodic tests on faulty lines. It was made so that it could be done.
局間回線が障害になった場合に、障害発生呼を別の回線

因の調査と修理とを行う。When a line between offices becomes faulty, the call can be connected by detouring the faulty call to another line. Further, by blocking the faulty line, it is possible to prohibit subsequent calls from seizing the faulty trunk. When a line fault is detected, the exchange notifies the user that the line is faulty, and maintenance personnel conduct tests on the faulty trunk in accordance with this fault notification information. If the test results are normal, the maintainer returns the trunk to operational status. If the test result is abnormal, the maintenance person investigates the cause of the failure and repairs it while keeping the trunk in a blocked state.
従来側では、障害によって閉塞された回線は保守者の手
動操作によってでしか運用状態に復旧することができな
いので、いったん障害によって閉塞された回線は障害が
復旧しても自動的に運用状態に復旧できない欠点があっ
た。On the conventional side, a line that is blocked due to a fault can only be restored to an operating state by manual operation by a maintenance person, so once a line that is blocked due to a fault is restored to an operating state even after the fault is recovered, the line is automatically restored to an operating state. There was a drawback that it could not be done.
本発明は、このような欠点を除去するもので、障害によ

復旧手段を起動するカウンタ手段を備えても良い。The present invention provides a line maintenance device equipped with a faulty line blocking means for detecting a faulty state of a line connecting between exchanges and blocking the faulty line, which periodically sends a test call to the faulty line, The present invention is characterized in that it includes a faulty line recovery means that determines whether to continue or release the blockage of the faulty line in accordance with the test results. Here, the faulty line blocking means may include a counter means that is provided corresponding to the line, starts counting when a line fault state is detected, and activates the faulty line recovery means when a predetermined value is counted.

運用状態に復旧させるかを決定する。A fault counter is provided for each line, and only when this counter exceeds a predetermined value is the line considered to be faulty. Furthermore, a test call is periodically generated for the faulty line to execute call connection processing to the other station. Depending on the result of this call connection test, whether to leave the line blocked or
Decide whether to restore it to operational status.
以下、本発明の一実施例について図面を参照して説明す

旧手段を起動するカウンタ手段を備える。As shown in FIG. 1, this embodiment includes faulty line blocking means for detecting a faulty state of lines 4 and 5 connecting exchanges 1, 2 and 3 and blocking the faulty line.
Further, as a feature of the present invention, a faulty line recovery means periodically sends a test call to the faulty line and determines whether to continue or release the blockage of the faulty line according to the test results. Equipped with Here, the faulty line blocking means is provided corresponding to the line, and includes a counter means that starts counting when a line fault state is detected and starts the faulty line recovery means when a predetermined value is counted.
次に、この実施例の動作を説明する。Next, the operation of this embodiment will be explained.

的に閉塞解除ができるようにする（ステップ１０４）。If a line failure occurs during call connection, a failure counter corresponding to the line is incremented (step E01). If the fault counter exceeds a predetermined reference value (step 1)
02), the line is regarded as a faulty line, and the line is blocked to avoid adverse effects on call connection (step 103). Further, automatic test registration is performed so that the blockage can be automatically released when the line condition is restored (step 104).

３）ので、回線状態は閉塞状態のままとなる。FIG. 3 is a flowchart of an automatic test for a faulty line. A test is performed on the line registered in step 104 of FIG. 2 (step 111). A test call is generated to the corresponding line (step 112). It has a database of calling numbers for each line group to which the line under test belongs (Figure 4).
This calling number is the telephone number of the automatic answering bag W6 of the other station A. If the line status is restored when the test call is connected, the call will be connected normally (step 113), so the line will be deleted from the automatic test line registration table (step 114), and the line status will be restored from blocked to operational. Enable call connection (
Step 115). On the other hand, if the line condition continues to be faulty, the test call will not be connected normally (step 11).
3), the line status remains blocked.
