Description

[Detailed Description of the Invention] [Summary] In a digital exchange equipped with a subscriber line test device and a subscriber line test stand, identification information of a fault reporting subscriber line is transmitted to the subscriber line test stand, and the identification information is transmitted to the subscriber line test stand. By setting a test route for testing a failure reporting subscriber line from the subscriber line test stand via the subscriber line test device, the operability of the subscriber line test stand is improved.

[Industrial application field]

The present invention relates to an improvement in a failure reception processing method in a digital exchange.

Subscriber line test stands installed in digital exchanges and used to test accommodated subscriber lines often also have the function of accepting failure reports from subscribers.

It is desirable that such a subscriber line test stand be able to immediately test a subscriber line for which a fault report has been received.

[Conventional technology]

FIG. 3 is a diagram showing an example of a conventional failure acceptance processing method in this type of digital exchange.

In Figure 3, subscriber line test equipment (LTE)
4, the accommodated subscriber line 2 is drawn in via the subscriber circuit (SLC) 3, and various tests such as line resistance, insulation resistance, line capacitance, etc., of the subscriber line 2 are conducted.

A subscriber line test stand (LTC) 8 is connected to a network (NW) 5 by a failure reception trunk (CPT) 6 and a subscriber line test trunk (LTT) 7.

When a subscriber who notices a fault dials a telephone number designated for fault reporting, the central control unit (CC) 9 sets up a call path p1 within the call path network 5,
A calling subscriber is connected to a subscriber line test stand 8 through a failure reporting route that passes through the subscriber line 2, the subscriber circuit 3, the communication path p1 in the communication path network 5, and the failure reception trunk 6.

When the operator of the subscriber line test stand 8 notices the incoming call to the failure reception trunk 6 and performs a response operation, it becomes possible to hear the failure report from the calling subscriber.

In order to confirm the fault status reported by the calling subscriber, after the operator has released the fault reporting route,
When a call is made from the subscriber line test trunk 7 and the telephone number of the subscriber reporting the problem is dialed, the central control unit 9 sets up a call path p2 within the call path network 5 and connects the subscriber line test trunk 7 and the subscriber line. At the same time, the subscriber circuit 3 corresponding to the received telephone number is controlled to draw the accommodated subscriber line 2 into the subscriber line testing apparatus 4, and a subscriber line test route is set.

The subscriber line test device 4 executes a test on the subscriber line 2 that has been drawn in based on test instructions transmitted via the subscriber line test path by the operator of the subscriber line test stand 8, and records the test results. The subscriber line test stand 8 is notified via the subscriber line test route.

The operator of the subscriber line test stand 8 confirms the reported failure status based on the test results returned from the subscriber line test device 4, and starts necessary repair processing.

[Problem that the invention seeks to solve]

In space-division type electronic exchanges, the communication path network was capable of transmitting direct current, so the subscriber line test stand could directly connect the failure report subscriber line via the failure report route, making it possible to perform various tests. It was hot.

However, in a digital exchange, the communication path network 5
Since direct current cannot be transmitted via the subscriber line test trunk 7 and the subscriber line test device 4, the fault reporting route is temporarily released as described above, and the telephone number of the fault reporting subscriber is selected again. There was a problem in that it was necessary to set a subscriber line test route, and it took time and effort to check the failure status.
