Description

[Detailed Description of the Invention] [Summary] In an automatic exchange equipped with a plurality of subscriber line test devices, a test stand each having a test control function and a test result recording function is provided, and the automatic exchange has a test stand and the test stand. By connecting the test equipment instructed from the stand and performing all test control and recording of test results for the connected test equipment from the test stand, the expansion of test functions will not affect the automatic exchange. is prevented.

[Industrial application field]

The present invention relates to a test connection method that allows the test function of accommodation lines provided in an automatic exchange to be expanded without affecting the automatic exchange itself as much as possible.

As the number of subscribers accommodated in automatic exchanges rapidly becomes more diverse and sophisticated, the testing functions that automatic exchanges should be equipped with are required to rapidly improve in a short period of time.

It is desirable to reduce the impact on automatic switchboards when such testing capabilities are frequently expanded.

[Conventional technology]

FIG. 3 is a diagram showing an example of a conventional test connection method in this type of automatic exchange.

In FIG. 3, the subscriber circuit (SLC) of automatic exchange 1
The subscriber lines 2 accommodated in the subscriber line 3 are controlled by a plurality of call processing processors (CPR) 6 provided with load distribution.
It is connected via a line concentrator (LC) 4 and a communication path m (NW) 5.

A management processor (MPR) 7 is in charge of overall management of the automatic exchange 1.

The maintenance person controls the operation of the automatic switchboard 1 by inputting required commands from the display unit (VDU) 10 to the management processor 7 via the input/output control unit (TPO) 9, and also controls the operation of the automatic switching equipment 1 The operating state of the automatic exchange 1 is monitored by various messages outputted to the display device 10 via the output control device 9.

In addition, the communication path M45 includes a failure reception trunk (CPT) 1.
A fault reception desk (CPC) 13 is connected via 2, and receives fault reports from subscribers.

In order to test the subscriber line 2, a number of subscriber line test equipment (LTE) 11 according to the number of accommodated subscriber lines and a number of subscriber line test stands (LTC) 15 according to the test frequency are provided. It is being

When all maintenance personnel enter the telephone number of the subscriber line 2 to be tested from the subscriber line test stand 15 in order to test the subscriber line 2, the call processing processor 6 sets the subscriber line test trunk (LTT).
) 14 and the scanning device (SCN) 8, selects the subscriber line testing device 11 corresponding to the subscriber line 2 to be tested, and selects the subscriber line testing device 11 that corresponds to the subscriber line 2 to be tested.
Two sets of communication paths are set up between the subscriber line test trunk 14 and the subscriber line test trunk 14 via the subscriber line test trunk 14.

Thereafter, when the maintenance person inputs a necessary command to set test conditions from the subscriber line test stand 15, a control signal corresponding to the command is sent from the subscriber line test trunk 14 to the subscriber line test device 11. Communication path fA5 and line concentrator 4
The signal is transmitted via one communication path (hereinafter referred to as test control path C) set within the test control path.

Based on the control signal transmitted via the test control path C, the subscriber line testing device 11 connects the communication path of the subscriber line 2 to be tested via the subscriber circuit 3, and performs various tests on the subscriber line 2 side. A test is carried out and a test connection is carried out from the subscriber circuit 3 to the automatic exchange 1. Note that the communication path drawn into the subscriber line testing device 11 is connected to the line concentrator 4 and the communication path 'lI45.
It is connected to the subscriber line test stand 15 via the other communication path (hereinafter referred to as test communication path V) set within the network and the subscriber line test trunk 14, so that a maintenance person can, for example, talk to a subscriber to be tested. becomes possible.

The maintenance person records the test results performed on the subscriber line 2 on a required form.

On the other hand, the management processor 7 sequentially activates each subscriber line testing device 11 via the call processing processor 6 at a predetermined period, causes each subscriber line 2 to perform an automatic test in a predetermined procedure, and outputs the results. The test results (pass/fail determination) are received via the call processing processor 6 and stored. When the series of automatic tests is completed, the management processor 7 outputs the stored test results to the display device 10 or the like.

[Problem to be Solved by the Invention 3] As is clear from the above explanation, in a conventional test connection system, a maintenance person controls the subscriber line test device 11 from the subscriber line test stand 15 to connect the subscriber line 2. I had to record the test results on paper myself.

However, it is desirable that such test results be automatically stored and managed as a failure history of the subscriber line 2.

The automatic test results periodically executed on subscriber line 2 are as follows:
Although it is stored by the management processor 7, the path for transmitting the automatic test results is not suitable for collecting a large amount of test data, and the stored automatic test results are limited to determining the quality of the subscriber line 2. For subscriber lines 2 that will become more diverse in the future,
It is unsuitable for storing detailed test result data corresponding to diversified test conditions.

Furthermore, incorporating the test function into the automatic switchboard 1 requires changes to the functions of the automatic switchboard 1, which are strongly required to perform real-time processing, each time the test function is expanded, which not only requires a large amount of man-hours. , the automatic exchange 1 in operation will be temporarily stopped.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention.

In FIG. 1, 1 is an automatic exchange and 100 is a subscriber line testing device.

200 is provided in accordance with the present invention for test control functions and for recording test results! This is a test stand with three functions.

[Effect]

The automatic exchange 1 connects the test stand 200 and the subscriber line testing device 100 instructed by the test stand 200.

Thereafter, the test stand 200 is connected to the subscriber line test equipment 10.
Execute all test controls for 0 and record test results.

Therefore, the automatic exchange 1 is only required to set up a communication path between the subscriber line test equipment 100 and the test bench 200 in the same way as normal call processing, and all expansion of test functions can be handled by the test bench 200. The automatic exchange 1 is not affected.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing a test connection method according to an embodiment of the present invention. Note that the same reference numerals refer to the same objects throughout the plan.

In FIG. 2, a telephone 21 and a personal computer (PC) 22 are provided as a test stand 200.

The telephones 21 are each connected to a communication path network (NW) 5 via a voice trunk (VT) 19 according to standard connection conditions, and the personal computers 22 are connected to a communication path "M" via an interface device (LTI) 20, respectively. (N
W) Connected to 5.

Further, the personal computer (PC) 22 is connected to the management processor (MPR) via the adapter (SIA) 16 according to standard connection conditions (for example, R3232C standard).
)'7 is also connected.

In FIG. 2, in order to test the subscriber line 2, a maintenance person enters the corresponding device number of the interface device 20 to which the maintenance person is connected from the personal computer 22 to the management processor 7 via the adapter 16. When a test connection request command containing the device number of the voice trunk 19 to which the telephone set 21 is connected and the telephone number of the subscriber line 2 to be tested is input, the management processor 7 receives the test connection request command received via the adapter 16. , selects the subscriber line test equipment (LTE) 11 corresponding to the subscriber line 2 to be tested, and connects the interface specified in the test connection request command via the communication path '4145 and the line concentrator (LC) 4. A request to set up a test control path C between the device 20 and the subscriber line testing device 11, and a test communication path ■ between the voice trunk 19 specified in the test connection request command and the subscriber line testing device 11. is transmitted to the call processing processor (CPR) 6.

The call processing processor 6, which has received the request for setting the test control path C and the test communication path V, sets the test control path C and the test communication path ■ in the same way as in normal call processing.

Thereafter, when the maintenance person inputs the necessary commands to set the test conditions from the personal computer 22, the subscriber line test equipment 11 is controlled? 'fll signal is communicated via test control path C and interface device 20.

Based on the control signal transmitted via the test control path C, the subscriber line testing device 11 draws in the communication path of the subscriber line 2 to be tested via the subscriber circuit (SLC) 3, and
various side tests are executed, and a test connection is executed from the subscriber circuit 3 to the automatic exchange 1. Note that the communication path drawn into the subscriber line testing device 11 is connected to the telephone set 21 via the test communication path V and the voice trunk 19, so that a maintenance person can make a conversation with, for example, a subscriber to be tested.

Note that the personal computer 22 stores test results performed on the subscriber line 2 one by one.

Furthermore, when a digital subscriber line is accommodated in the automatic exchange 1, it becomes necessary to measure the bit error rate of the digital subscriber line. In such a case, the personal computer 22 issues a test connection request command that includes the device number of the bit error rate measuring device (BER) 23 connected to the communication path y45 and the telephone number of the digital subscriber line to be tested. By inputting the information into the management processor 7, the call processing processor 6 performs the communication with the subscriber line test equipment 11 designated by the management processor 7, in the same way as normal call processing.
) A test control path C and a test communication path V are set up between the bit error rate measuring device 23 and the bit error rate measuring device 23 passes through the test communication path V and the subscriber line testing device 11, and the test target digital Perform subscriber line measurements.

In the same process as described above, the management processor 7 causes each subscriber line 2 to perform an automatic test according to a predetermined procedure, and stores the test results (pass/fail determination).

When the series of automatic tests is completed, the management processor 7 transmits the stored test results to the personal computer 22 via the adapter 16.

The personal computer 22 also stores the test results transmitted from the management processor 7.

The maintenance person can output the test results stored in the personal computer 22 at any time.

The maintenance person connects the adapter 1 from the personal computer 22.
By inputting the required commands to the management processor 7 via 6, the aforementioned display device 10 (FIG. 3)
Similarly, the operation of the automatic exchange 1 is controlled, and the operating status of the automatic exchange 1 is monitored by the management processor 7 outputting various messages to the personal computer 22 via the adapter 16.

Further, a failure report from a subscriber is accepted by a telephone 18 connected to the communication path network 5 via a voice trunk (VT) 17.

As is clear from the above description, according to this embodiment, when testing the subscriber line 2, the call processing processor 6 performs the same call path setting as in normal call processing based on instructions from the management processor 7. The subsequent control of the subscriber line testing device 11 and recording of test results are all executed by the personal computer 22. Note that, unlike the call processing processor 6 and the like, which are strongly required to perform real-time processing, the personal computer 22 can easily accommodate new functional expansions by updating programs written in a general-purpose language. The test function can be expanded without having the same effect on the operation of the L. In addition, even when a new test is required, such as error rate measurement for digital subscriber lines, the call processing processor 6 is only required to set up a communication path in normal call processing, and detailed test items are not included. Since the test function is processed by an external device such as the bit error rate measuring device 23, the test function can be expanded without affecting the call processing function of the automatic exchange 1.

Note that FIG. 2 is only one embodiment of the present invention, and for example, the test stand 200 is not limited to one composed of a telephone 21 and a personal computer 22, and data can be easily recorded and edited. The effects of the present invention will remain the same as long as it can be realized and easily meet diversifying demands. Further, the external device for special testing is not limited to the bit error rate measurement device 23, and various external devices may be considered based on newly generated test requests, but the effects of the present invention will not be affected in any case. Furthermore, the telephones 18 and 21 are not limited to being installed separately; for example, it is also possible to combine them into a telephone terminal device capable of accommodating multiple lines, but the present invention also applies in such a case. The effect remains unchanged. Furthermore, it goes without saying that the configuration of the automatic exchange to which the present invention is applied is not limited to that shown in the drawings.

[Effects of the Invention] As described above, according to the present invention, the automatic switching system is only required to set up a communication path between the test equipment and the test stand in the same way as normal call processing, and all expansion of test functions is performed on the test stand. It can be processed by , and the automatic switching machine will not be affected.
