[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention provides a terminal device testing method that enables testing of a plurality of terminal devices having a telephone function or a packet connection function connected to a telephone line or a packet switching line. Regarding.

(2) Prior Art and Problems For example, so-called data telephone devices have recently been developed that are connected to a host processor at a center via a telephone line to manage product sales and the like. Some data telephones have a plasma display, a keyboard, or a printer. Conventionally, when testing such a device, as shown in FIG. We were doing a one-on-one test. Therefore, the test efficiency is poor, and it is not possible to perform a message exchange test with other terminal devices under test, so there are problems as a test method.

(3) Purpose of the Invention The purpose of the present invention is to provide a terminal device testing method that improves the above-mentioned problems and enables simultaneous testing of a plurality of terminal devices connected to an exchange.

(4) Structure of the Invention In order to achieve this object, the terminal device testing method of the present invention includes a test item storage means in which a plurality of test items are stored, and a test execution control for extracting test items from the test item storage means. A test method for testing terminal devices connected via an exchange, which includes a central testing equipment equipped with a means for testing terminal devices connected via an exchange, in which multiple terminal devices with different transmission and reception methods are connected to the exchange, and the connection supports multiple types of transmission and reception methods. The present invention is characterized in that means is provided in the central testing equipment to test data transmission systems between a plurality of terminal devices to be tested connected to the exchange based on the test items.

(5) An embodiment of the invention An embodiment of the invention will be described based on FIGS. 2 to 4.

FIG. 2 is a schematic configuration diagram of the present invention, FIG. 3 is a detailed diagram of a pseudo center which is the main part of the present invention, and FIG. 4 is an explanatory diagram of various test states of the present invention.

In the figure, 4-0 to 4-3 are terminal devices to be tested, 5 is a switch, 6 is a pseudo center, 7 is a PB center, 8 is a FG center, 10-0 to 10-3
is a modem, 11-0 and 11-1 are PB signal converters,
12 is a channel connection section, 13 is a line control section, 1
4 is a test execution control section, 15 is a test item storage section, 16 is a system management section, and 17 is a console.

The exchange 5 has a plurality of terminal devices 4 to be tested.
It is connected to 0 to 4-3 by lines, and is also connected to the pseudo center 6 by a plurality of lines.

The pseudo center 6 is a test device for testing the terminal devices 4-0 to 4-3, and its detailed configuration is shown in FIG. It consists of a PB center 7 that performs FM modulated transmission, an FB center 8 that transmits and receives FM modulated signals, and a test control management section (not shown in Figure 2) that is commonly connected to each of these centers. ing.

Modems 10-0 to 10-3 are modems that modulate and demodulate signals, and demodulate FM modulated signals transmitted from the line, or FM modulate signals to be sent to the line. ,1
0-3 constitute FS center 8. Moreover, the line speed can also be selected according to the selection from one of the terminal devices 4-0 to 4-3.

The PB signal converters 11-0 and 11-1 receive the push button signal and convert it into a normal signal, and the modems 10-0 to 10-1 and the PB
The signal conversion devices 11-0 and 11-1 constitute the PB center 7.

The test execution control unit 14 is a test item storage unit 15.
The test items T ₁ , T _{2 .} . . T _N are extracted from the test items T 1 , T 2 , .
Alternatively, it is transmitted directly to the terminal device under test and then transmitted to the operator. Of course, the same test item can be tested on a plurality of terminal devices, for example, by time-sharing control.

The test item storage unit 15 stores a plurality of test items T ₁ , T _{2 .} . . for testing the terminal device.
Each test item stores data necessary for executing that test.

The system management unit 16 is a control unit that manages the overall status of the pseudo center 6, and also includes test items.
The execution results of T ₁ , T _{2 .} . . T _N and the test items currently being executed are stored.

The console 17 includes a display section for displaying the test status, a control panel for controlling the test status,
Switches, RAM, etc. are located here.

Next, a test performed in the present invention will be explained based on FIG. 4. The test formats can be broadly divided into (a) conversation test, (b) message exchange test, and (c)
There is a distribution test and (d) reception test. (a) What is a conversation test? The tester using the terminal device 4 calls the simulated center 6 via the switchboard, and the simulated center 6 instructs the test operation on a plasma display or the like. , and the test data input results are transmitted to the terminal device 4, which corresponds to a functional test, etc. (b) What is the message exchange test? Terminal device 4-A
Data destined for the terminal device 4-B is input from the pseudo center 6, and the input data is transmitted from the pseudo center 6 to the terminal device 4-B, and the result is received from the terminal device 4-B. This applies to face-to-face exams, etc. (c) Distribution test is a test to determine whether the terminal device 4 has correctly received the data sent unidirectionally from the pseudo center 6. For example, the distribution test is a test to determine whether the terminal device 4 has correctly received the data sent unidirectionally from the pseudo center 6. This applies to continuous testing of equipment, etc. (d) Concentration test is one in which data is sent in one direction from the terminal device 4 to the pseudo center 6,
Continuous testing of input devices, etc. falls under this category.

Next, the test method of the present invention will be explained in detail based on FIGS. 2 and 3.

Modems 10-0 to 10-3 are each connected to exchange 5.
The exchange 5 is connected to terminal devices 4-0 to 4-3 to be tested. The system management unit 16 manages these terminal devices 4-0 to 4-3.
The control table determines which test item is being executed by a management table (not shown), and instructs the test execution control unit 14 which test item to execute. Normally, the test is executed in the order of test items T ₁ , T _{2 ,} .

For example, if the system management unit 16 instructs the terminal device 4-0 connected to the modem 10-0 to execute a test using test item _T1 ,
The test execution control unit 14 reads the test item _T1 from the test item storage unit 15, and based on this, transmits control data to the terminal device 4-0 via the line control unit 13-channel 0-modem 10-0, Test this. The system management unit 16 then informs the system management unit 16 of the test result whether the test ended normally or was abnormal.
Report to. The system management unit 16 stores the results in the management table and performs the next test item.
Instructs to execute T ₂ . In this way, all tests are performed on the terminal device 4-0,
If it is normal, the system management unit 16 displays this on the console 17 or the terminal device 4-0.
report to the tester. If there is an abnormality, the results will be reported in the same manner. In addition, when there is an abnormality in the line, the line control unit 13 sends it to the system management unit 16.
This makes it possible to distinguish whether an abnormality during a test is caused by the equipment under test or by a line error.

(6) Effects of the Invention According to the present invention, it is possible to simultaneously test a plurality of terminal devices under test that are connected to an exchange and used. Moreover, arbitrary tests can be simultaneously and selectively performed on a plurality of devices under test. In addition, since tests can be performed from any location as long as a line can be connected to the exchange, tests can be performed once installed on the user's side. Additionally, the line speed of the tester can be set arbitrarily from the device under test. The test format is also not one-to-one between the test machine and the device under test, as in the past, so conversation tests,
Message exchange tests, delivery tests, reception tests, etc. can be executed.
