トランクの場合を説明する。第５図に示した如く。Hereinafter, an overview of the conventional techniques described in the above-mentioned known documents will be explained. FIG. 5 is a diagram showing the positioning of the abnormality monitoring device on the exchange system, where 1 is the abnormality monitoring device, 2 is the exchange interface device, 3 is the switch, 4 is the exchange control device, and 5 is the fault display panel. . Depending on local circumstances, the exchange interface device 2 may be a subscriber circuit or a trunk, but the basic concept is the same, so below:
The case of trunk will be explained. As shown in FIG.
外部監視装置は、信頼性向上の為、トランク２回路と接
続される。The external monitoring device is connected to the trunk 2 circuit for improved reliability.
外部監視装置は、内部の時限回路１ｓにより、あらかじ

正常稼動を確認する。The external monitoring device periodically activates the trunk via the activation circuit 11t at nine predetermined cycles by the internal timer circuit 1s. A response signal from the exchange in response to activation is confirmed by a response confirmation circuit 12 to confirm normal operation of the call processing program.

に対する不応答は、呼処理の停止と判断せず、障害表示
パネルの障害表示、及び異常監視装置の計数回路１４の
歩進のみを行う。When the call processing program is stopped, the response confirmation circuit 12 does not detect a response signal from the trunk side, and the response confirmation circuit outputs alarm signals ALU and ALI. This alarm signal is displayed on the failure display panel 5 and notified to maintenance personnel, and is also logically multiplied and passed through the counting circuit 140. In order to improve the reliability of the abnormality monitoring device, a non-response to a single call is not judged as a stoppage of call processing, but only the failure is displayed on the failure display panel and the counting circuit 14 of the abnormality monitoring device is incremented. .
本状類で、次の周期の起動が行なわれ、トランク不応答

ＭＡ信号を受信すると再開処理を行い、呼処理グ四グラ
ムを再ロードし、再びサービス会インの状態に入る。In this situation, when the next cycle of activation is performed and trunk non-response is detected, it is determined that call processing is stopped due to 2@continuous non-response, and the abnormality monitoring device performs emergency activation of the control device 4. . As for the alarm for the second autonomous call, the counting circuit increments 140 steps in the same manner as described above. The counting circuit 14 activates the emergency activation circuit 15 after counting twice. When the emergency activation circuit 15 is activated, it sends an initial setting signal (IMA signal) ``Ik'' to the control table @4.
When receiving the MA signal, it performs restart processing, reloads the call processing program, and enters the service session-in state again.

6 is the abnormality monitoring device and the electrical change f, itI! between the trunk and the activation @O when it is not activated and when it is activated. It is confirmed that the activation signal from the abnormality monitoring device normally reaches the ) rank based on the activation information from the activation circuit 11 and the conditions of electrical changes in the activation lead.

急起動回路を起動しない。Due to the disconnection, the activation signal does not reach the trunk, so the response signal from the trunk is not detected by the response detection circuit 12, and a failure indication is output to the failure display panel 2. on the other hand,
Since the activation confirmation signal 5TO1S'r1 is in the OFF state, the counting circuit 15 that counts the number of non-responses
[Since ALO and ALl are not set, it does not advance one step and does not activate the emergency activation circuit.

計数回路は歩進する。When the abnormality monitoring device and the trunk are connected normally, the startup confirmation signal 5TO1S at startup? Since 1 is set, when call processing actually stops and there is no response from the trunk, the logical product of the non-response output of the response detection circuit 12 and 5TO1S of 1 is input to the counting circuit 14. The counting circuit steps.
