Abstract

PROBLEM TO BE SOLVED: To provide a maintenance system for an exchange capable of managing fault for each exchange independently and besides only for designated line/ subscriber's line, and of performing a line test. SOLUTION: This exchange 10 is provided with an alarm managing part 12 connected to a maintenance terminal 11, a fault detecting part 13 detecting a fault of a line/subscriber's line, a fault information receiving part 14 that decides whether or not fault information is information about the fault/error of a line/subscriber's line registered with a maintenance person and performs a fault message output request to the part 12 when it is other than information about the fault/error of the registered line/subscriber's line, a fault information storage processing part 16 that stores fault information and performs statistic processing in every line/subscriber's line to store it in a file 15 when it is a fault/error of the registered line/subscriber's line, and a test functioning part 17 which refers to the file 15 and executes an automatic test of the line/ subscriber's line where the fault occurs.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an exchange,
The present invention relates to a maintenance system for an exchange that detects a fault in a line / subscriber line, performs alarm processing, and tests the line / subscriber line.

[0002]

2. Description of the Related Art As shown in FIG. 2, a general maintenance system for a conventional switchboard includes an alarm management unit 2 for notifying an external maintenance terminal 1 of an alarm and a fault detection for detecting a fault on a line / subscriber line. A function of testing a line / subscriber line in which a failure has been detected by simply providing a failure information receiving unit 4 that receives failure information from the failure detection unit 3 and requests the alarm management unit 2 to output a failure message. Was not.

On the other hand, JP-A-6-62116 discloses that
In a network system including a plurality of switching processing devices and a network management device for centrally managing the switching processing devices, the network management device includes an important line management unit that manages a frequency of occurrence of a failure of an important line for each switching processing device;
There is disclosed a line monitoring system including a notifying unit for notifying a maintenance person of a higher failure level of an important line and a line test requesting unit for causing a switching processor to execute a line test of the important line.

[0004]

However, in this network management apparatus for centrally managing a plurality of switching processing apparatuses, a fault is managed and a line test is performed. The line test cannot be performed by managing the failure of the subscriber line.

SUMMARY OF THE INVENTION An object of the present invention is to provide an exchange maintenance system capable of performing a line test independently of each exchange and managing a fault only for a designated line / subscriber line.

[0006]

According to the present invention, there is provided an alarm management unit connected to a maintenance terminal, a failure detection unit for detecting a line / subscriber line failure, and receiving failure information from the failure detection unit. It is determined whether or not the failure information is information relating to a failure / error of the line / subscriber line registered with the maintenance person. If the failure information is other than the information relating to the failure / error of the registered line / subscriber line, the failure information is provided. And a fault information receiving unit that only issues a fault message output request to the alarm management unit, and stores a fault information and a line / subscriber when a fault / error occurs in the registered line / subscriber line. A failure information storage processing unit that performs statistical processing for each line and saves it in a file;
A test function unit for executing an automatic test for a subscriber line;
It is characterized by being provided in an exchange.

The test function section can also perform an automatic test by specifying a failure information file by a maintenance person.

That is, according to the present invention, a fault report autonomous message (alarm function) output when a line / subscriber line fault occurs in an exchange is managed by number, and statistics are taken for each faulty line / subscriber line. Save to a file regularly. When the number of failures exceeds a threshold value or when a file is periodically output, an automatic test is performed on the failed line / subscriber line. Also, a test can be executed by a maintenance person by specifying a file.

[0009]

Embodiments of the present invention will now be described with reference to the drawings.

In FIG. 1, an exchange 10 includes an alarm management unit 12 connected to a maintenance terminal 11, a failure detection unit 13 for detecting a failure of a line / subscriber line, and a failure detection unit 1.
3, a failure information receiving unit 14 for determining whether the failure information is information relating to a failure / error of the line / subscriber line registered by the maintenance person, and a registered line / subscriber line. In the case of a failure / error, the failure information storage processing unit 1 stores the failure information, performs statistical processing for each line / subscriber line, and stores it in a file (disk) 15.
6 and a test function unit 17 for executing an automatic test on the failed line / subscriber line with reference to the file 15
And are provided.

Next, the operation will be described. When a failure occurs, the failure information (terminal number, failure type, etc.) is transferred from the subscriber line resource management unit and various protocol units, that is, the failure detection unit 13, to the failure information receiving unit 14. Fault information receiving unit 14
If the received fault information is other than the information related to the fault / error of the line / subscriber line registered by the maintenance person, the fault information is formatted and only a fault message output request is sent to the alarm management unit 12.

On the other hand, if the failure information is information relating to a failure / error of the line / subscriber line registered by the maintenance person to use this function, the failure information storage processor 16 stores the failure information. Also, statistical processing is performed for each line / subscriber line.

In this failure information storage processing, the failure count result is output to a file when all the storage areas are used or at regular intervals determined by the maintenance person, and a message to that effect is output. At the time of this file output, the failure information receiving unit 14 reports to the test function unit 17 that the failure information statistical file has been output, and upon receiving this notification, the test function unit 17 / Perform an automatic test on the subscriber line. Further, by giving an identifier to the file, an automatic test for specifying a failure information file by a maintenance person is also possible.

[0014]

According to the present invention, it is possible to carry out a line test independently for each exchange, and to manage a fault only for a specified line / subscriber line. By providing a level of failure or error that does not give
Alarms that are often overlooked by maintenance personnel can be automatically and periodically tested to detect line / subscriber line anomalies before they become serious problems.
