Abstract

PURPOSE:To test easily a line even when an electronic exchange stores plurally divided lines by changing an area belonging to the test terminal to which the testing device is connected, at testing a line. CONSTITUTION:An electronic private exchange 1 is composed of trunks 10a-10d, a network 11, subscriber circuits 12a-12h and a control device 13. The exchange 1 is used for two tenants A and B, and the trunks 10a and 10b and the subscriber circuits 12a-12d are classified to the area of the tenant A and the remainder is classified to the area of the tenant B. A circuit testing device 2 is connected to a subscriber circuit 12h of a tenant B area, the line of the area B is tested, and then, the test signal is emitted as it is and the line is tested. When the line of the area A is tested the control device 13 changes the area to which a subscriber circuit 12h belongs, from B to A, and is tested in the same way. Thus, all lines can be tested without changing the connection of the testing device 2.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a line testing method for electronic exchanges.

The method of the present invention is used, for example, for line testing of electronic private branch exchanges in which the accommodated line is divided into multiple tenants.

[Conventional technology]

Conventionally, when performing line tests on electronic private branch exchanges, one of the subscriber circuits or trunks accommodated in the exchange is set as a test terminal, and the line test equipment and the line under test of the exchange are connected via this test terminal. Connect and perform a line test. When performing this line test, the attribute information of the line under test, such as dial pulse (DP) method or pushbutton (P
B) method or multi-frequency (MF) method, or whether there is a connection confirmation signal or not, there are cases where the test cannot be performed unless the test equipment has information.

Therefore, when testing a line, when the line testing equipment notifies the private branch exchange of the line number of the line under test, the private branch exchange sets the line under test to test mode, and also tells the line testing equipment the attributes of the line under test. It will notify you of information. Based on this attribute information, the tester can operate the line test equipment to perform the test.

[Problem that the invention seeks to solve]

The configuration of an electronic private branch exchange installed in a multi-tenant building etc. is shown in Figure 1 (al). 10 (a) ~ 10Fdl, network 1
1, subscriber circuit 12 (al ~ 12 (hl), control device 1
The subscriber circuit 12 (th) is set as a test terminal and connected to the line test device 2.

In such a private branch exchange, its accommodation lines are divided into a plurality of tenants, tenants A and B in FIG. The exchange is configured in terms of software so that lines with different tenant numbers (that is, lines belonging to different tenants) cannot be directly connected within the exchange.

Therefore, when performing a line test, if it is within the tenant to which the test terminal belongs, the line test equipment can be connected to the line under test in that tenant via the test terminal. There is a problem in that the line test equipment cannot be connected to a tenant with a different number from the tenant number, and line tests cannot be performed.

Therefore, in the past, in order to conduct a line test for each of multiple tenants, it was necessary to reconnect the test terminal in each tenant in the exchange, making the line test extremely time-consuming and, in the end, Tests cannot be conducted frequently, hindering early detection of disabilities.

[Means for solving problems]

In order to solve the above-mentioned problems, in the present invention, attribute information of the line under test is transmitted and received between an electronic exchange that accommodates a plurality of lines divided into a plurality of areas, and the electronic exchange. A test device that performs a test, the test device includes:
In a line test method for an electronic exchange configured to perform a line test by connecting the line under test through a test terminal set within a certain area of the electronic exchange,
During a line test, the electronic exchange shall perform processing to change the area number to which the test terminal belongs to the area number to which the line under test belongs, thereby enabling connection between the test terminal and the line under test and performing the line test. Provided is a line testing method for electronic switching equipment characterized by the following.

[For production]

When connecting from a specific test terminal to the line under test for line testing, when notifying the line attributes from the test equipment side to the exchange side, the area (tenant) number to which the line under test belongs is also notified. By doing this, the area number to which the test terminal belongs is set to be the same as the area number of the line under test. This enables connection between the line testing device and the line under test belonging to any area number.

〔Example〕

The configuration of a system for performing a line test method for an electronic exchange as an embodiment of the present invention is shown in FIG. 1 (al).
