Abstract

PURPOSE:To efficiently execute the test by supplying command data from an arbitrary data terminal stored in a data terminal storage circuit to test a desired terminal or terminal storage circuit from an arbitrary place. CONSTITUTION:A central controller 20 has a test function in dicating means 210 and controls a main switch 10 to control a terminal storage circuit 30 and a data terminal storage circuit 40 through an internal control bus 70. The terminal storage circuit 30 has a test function control means 310 and stores a terminal 50, and the data terminal storage circuit 40 has a command data transmitting and receiving means 410 and stores a data terminal 60. Command data is supplied from the arbitrary data terminal 60 stored in the data terminal storage circuit 40 to test the desired terminal 50 or terminal storage circuit 30 from an arbitrary place. Thus, the data terminal nearest to the terminal to be tested is used to efficiently execute the test.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a test function control method for an exchange.

[Conventional technology]

The conventional test function control method for switching equipment allows tests to be executed only from predetermined maintenance terminals in each system. This will be explained with reference to the drawings.

FIG. 2 is a block diagram showing a conventional test function control method for an exchange.

In FIG. 2, the central control device 20 includes a test function control means 220, and controls the main switch 10 and the terminal accommodation circuit 30 via an internal control bus 70. The terminal accommodating circuit 30 accommodates a terminal 50. Maintenance terminal 80 is connected to central control unit 20 via internal control bus 70 .

Next, the test operation will be explained.

First, a maintenance person who wants to perform a test operation can use the maintenance terminal 80 to
Enter the command for the test you want to execute. Commands input from the maintenance terminal 80 are sent to the central control unit 20 via the internal control bus 70. The central controller 20 analyzes the received command and uses the test function control means 220 to execute the test. If it is a call path test for the terminal 50, the maintenance person who performed the test operation should move to the location where the maintenance terminal 50 is installed or ask another person to confirm the test result. was.

[Problem to be solved by the invention]

In the conventional exchange test function control method described above, test operations were executed only from maintenance terminals predefined in the system, so if the control circuit or control bus to which the maintenance terminal is connected is malfunctioning, the test The problem was that it was not possible to execute. Another problem was that when testing was to be carried out, it was necessary to go to the location where the maintenance terminal was installed. This makes it difficult to proceed with the test efficiently when the installation location of the terminal to be tested and the installation location of the maintenance terminal are far apart.

An object of the present invention is to provide a test function of an exchange that allows testing of a desired terminal or terminal accommodation circuit from any location by inputting command data from any data terminal accommodated in the data terminal accommodation circuit. The objective is to provide a control method.

[Means to solve the problem]

A test function control method for an exchange according to the present invention is a test function control method for an exchange that accommodates data terminals via a data terminal accommodating circuit, in which instructions from a central control unit of the exchange are transmitted within the terminal accommodating circuit that accommodates the terminals. A test function control means for executing a test function such as a loopback according to the above is provided, and a command data transmitting/receiving means for transmitting and receiving command data sent from the data terminal to and from the central control device is provided in the data terminal accommodating circuit. A test function instructing means is provided in the central control unit for analyzing the received command data and instructing a designated terminal accommodation circuit to execute a test function.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, the central control unit 20 has a test function instruction means 210, controls the main switch 10, and controls the terminal accommodating circuit 30 and the data terminal accommodating circuit 4° via an internal control bus 70. The terminal accommodating circuit 30 has a test function control means 310 and accommodates the terminal 50. The data terminal accommodation circuit 40 includes a command data transmitting/receiving means 410
and houses a data terminal 60.

Next, the test operation will be explained.

First, a maintenance person who wants to perform a test function such as loopback inputs the accommodation location information or extension number of the party he wants to test from the data terminal 60 and the test function identification number (for example, if 1 is R
OM check, if 2, loopback check, etc.). The command data transmitting/receiving means 410 in the data terminal accommodating circuit 40 receives the data input from the data terminal 60, and then sends the data as command data from the data terminal accommodating circuit 40 to the central control unit 2 via the internal control bus 70.
Send to 0. The central control device 20 receives the command data transmitted from the data terminal accommodation circuit 40, analyzes the received command data, selects the terminal accommodation circuit 30 to be tested, and sends the data to the selected terminal accommodation circuit 30. ,
The test function instructing means 210 is used to instruct, via the internal control bus 70, a control command for instructing the control of the test function IIJ based on the received command data.

The test function instruction means 210 can be realized primarily as a single software program within the central control unit 20. The terminal accommodating circuit 30 uses the test function control means 310 in the terminal accommodating circuit 30 to execute a test according to instructions from the central controller 20.

〔Effect of the invention〕

As explained above, the present invention makes it possible to test a desired terminal or terminal accommodation circuit from any location by inputting command data from any data terminal housed in the data terminal accommodation circuit. There is an effect. As a result, the test can be performed using the data terminal closest to the terminal to be tested.
