Abstract

PURPOSE:To make the test equipment small by testing a tested equipment connecting to an electronic exchange via an integrated bus by means of a computer provided separately without use of a central controller of the electronic exchange. CONSTITUTION:Various test command such as test items of tested equipments are entered from a personal computer 1. An entered test command order is stored in a buffer 3 via a personal computer interface section 2. The personal computer 1 informs the end of transmission to the buffer 3 when the transmission by one control order is finished. The buffer 3 receiving the notice of the end of transmission by one control order outputs a control order of a computer format stored to an integrated bus interface section 4. The integrated bus interface section 4 converts the control order of the computer format outputted from the buffer 3 into a test control data of the integrated bus format and outputs the result to an integrated bus 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for testing an integrated bus connection device in an electronic exchange.

[Conventional technology]

Conventionally, testing of integrated bus connection devices in electronic exchanges of this type has been performed using a central control unit included in the electronic exchange.

[Problem to be solved by the invention]

The conventional test method for integrated bus connection devices in electronic exchanges described above uses the central control unit of the electronic exchange, so the test equipment becomes larger and the program is written in a dedicated language, requiring separate program development tools. There was a drawback.

An object of the present invention is to test a device under test connected to an electronic exchange via an integrated bus by using a separately provided computer without using the central control unit of the electronic exchange. Our goal is to provide the following.

[Means for Solving the Problems] The method for testing an integrated bus connection device in an electronic exchange according to the present invention is a method for testing an integrated bus connection device in an electronic exchange, in which a device that is directly controlled from a central control device of an electronic exchange via an integrated bus is Accumulating the control orders of the test program to be sent out, converting the accumulated control orders in the computer format into control data in the integrated bus format, receiving control data sending completion information output by the computer after sending out the control orders, sends the take to the device under test connected via the integrated bus, and the device under test receives and outputs the control data, converts the answer data from the integrated bus format to the computer data format, and stores the answer data. , and is configured to output the accumulated data to the computer in accordance with a reading instruction from the computer.

〔Example〕

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

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

FIG. 1 shows control orders output from a personal computer 1 that creates and executes a test program, a personal computer interface unit 2, a personal copier, and a device under test (not shown). The control order from the personal computer stored in the buffer 3 is converted into an integrated bus formant and output to the integrated bus, and the answer data of the device under test is transferred from the integrated bus. Integrated path interface x that converts personal format to tough format
- bus unit 4, integrated bus, etc.

Test items and other various test instructions for the device under test are input from the personal computer 1. The input test instruction orders are stored in the buffer 3 via the personal computer interface unit 2. When the personal computer 1 completes sending out one control order, it notifies the buffer 3 of the completion of sending. The buffer 3, which has received the notification of completion of transmission for one control order, outputs the stored control orders in computer format to the integrated bus interface section 4. The integrated bus interface section 4 converts the control order in computer format outputted by the buffer 3 into test control data in integrated bus format, and outputs the test control data on the integrated bus 51\. The test control data output to the integrated bus 5 is connected to the device under test via the integrated bus controller. The device under test operates according to the received test control data, and outputs the test results as answer data to the integrated bus interface section 4 via the integrated bus 5. The answer data from the device under test is converted from the integrated bus format to the computer format by the integrated bus interface section 4 and stored in the buffer 3. The personal computer 1 sends out the read order and receives the answer data from the device under test stored in the buffer 3.
The data is read through the personal computer interface section 2 and the test results are obtained.

〔Effect of the invention〕

As explained above, the present invention allows testing of equipment connected via an integrated bus without using the central control unit of the electronic exchange, which allows for downsizing of the testing equipment and furthermore enables the use of a general-purpose basic language. This makes it possible to create a test program by talking, making program development easier and reducing the need for dedicated program development tools.
