Abstract

PURPOSE:To implement the test without mistake even without having to carry an instruction manual by a test personal, relying on memory or training of the test personnel by returning the procedure of test and the result of test by voice synthesis from an electronic circuit. CONSTITUTION:When a connecting number from a subscriber's telephone set 1 to a test equipment is dialed, a telephone exchange 2 is switched to a line interface circuit 4 of a test device by a subscriber line interface circuit 3 to start a test control circuit 5. The test control circuit 5 reads a digitized test start message from a voice segment storage circuit 6 and allows a digital/analog conversion circuit 7 to convert the message into an analog voice signal and returns it to the subscriber's telephone set 1 through an amplifier 8. The test personnel proceeds the test operation, a measuring circuit 9 applies measurement to send the measuring result to the test control circuit 5. The test control circuit 5 converts the set result into the analog voice and returns it to the subscriber's telephone set 1. Thus, the test is implemented without mistake.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for testing a telephone in a subscriber's premises, in particular, a telephone in a subscriber's premises is connected to a testing machine installed in a switchboard housed therein to obtain test results. Concerning subscriber premises telephone testing method.

[Conventional technology]

Conventionally, in this type of customer premises telephone testing method, the telephone in the subscriber's premises is operated from the subscriber premises telephone according to predetermined procedures, and the test results from the test machine are displayed such as the ring tone and various other information. Judgments are made by listening to identification tones.

[Problem that the invention seeks to solve]

However, the conventional subscriber premises telephone testing method described above is
In order to perform the test in the correct order, the tester must be sufficiently trained and must refer to the procedure manual, and if the procedure is incorrect, the test result may be misinterpreted or a repeat test may be required. There are drawbacks.

In addition, obtaining the test results relies on the ringing tone and various identification tones, which also relies on the carrying of instructions and the tester's memory, which has the drawback of being easy to make mistakes.

There is a high possibility of mistakes, especially when the tester is a new person or the exchanger model is different, and there are many problems caused by the different models.

[Means for solving problems]

In the subscriber premises telephone test method of the present invention, a telephone in the subscriber's premises calls the test equipment of the telephone exchange accommodating the telephone, and the performance of the telephone and the characteristics of the line to this telephone are determined without the intervention of the maintenance personnel of the exchange. In the subscriber's premises test method, the tester conducts a test and reports the test results to the test person at the subscriber's premises. After receiving the call, a synthesized voice is sent out as specified by the test control circuit, the tester operates the telephone according to this synthesized voice, and the test control circuit repeats the process of sending out the measurement results again using the synthesized voice. It is constructed by conducting a series of tests.

〔Example〕

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

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

In the figure, a telephone 1 in a subscriber's premises is connected to a telephone exchange 2 via a subscriber line interface circuit 3. The subscriber line interface circuit 3 is provided with a switch for switching the subscriber line to the test line interface circuit 4 in response to a specific test dial from the telephone 1.The 0 line interface circuit 4 includes a test control circuit 5. A measuring circuit 9 and an amplifier 8 for voice response are connected. The test control circuit 5 is connected to a sound piece storage circuit 6 which controls the measurement circuit 9 and receives test results, and the sound piece storage circuit 6 sends its output to a digital-to-analog conversion circuit 7 to Conversion circuit 7
is configured to send its output to an amplifier 8.

In the above configuration, when the telephone 1 in the subscriber's premises dials the number for connection to the test equipment, the telephone exchange 2 is switched by the subscriber's line interface circuit 3 to the line interface circuit 4 of the test equipment. The line interface circuit 4 then activates the test control circuit 5. The test control circuit 5 reads out the digitized test start message from the speech piece storage circuit 6, converts it into an analog voice via the digital-to-analog conversion circuit 7, and passes it through the amplifier 8.
It is sent back to the subscriber's premises telephone 1 via the line interface circuit 4. The tester proceeds with the test operation based on the message, the measurement circuit 9 performs measurements, and sends the measurement results to the test control circuit 5. The test control circuit 5 reads out the digital message corresponding to the sent result from the speech piece storage circuit 6, converts it into an analog voice via the digital-to-analog conversion circuit 7, passes it through the amplifier 8, and sends it via the line interface circuit 4. and returns it to the subscriber's premises telephone 1.

The test control circuit 5 executes the above operations in a predetermined order and completes the series of tests.

〔Effect of the invention〕

As explained above, in the present invention, the test procedure and test results are returned by voice synthesis using an electronic circuit, so the tester does not have to carry an instruction manual, is dependent on his or her memory, and is not required to train the tester. This has the effect of allowing you to complete the test without making any mistakes.

Claims (1)

[Claims] A telephone at the subscriber's premises calls up a testing machine of the telephone exchange that accommodates the telephone, tests the performance of the telephone and the characteristics of the line to this telephone without involving the maintenance personnel of the exchange, and then tests the performance of the telephone and the characteristics of the line to this telephone without involving the maintenance personnel of the exchange. In the subscriber premises test system that notifies the test results, the test equipment has a measurement circuit, a speech synthesis circuit, an interface circuit for the line, and a test control circuit, and after a call is received by the test equipment, it is A series of tests is performed by repeatedly transmitting a synthesized voice, the tester operating a telephone according to the synthesized voice, and the test control circuit transmitting the measurement results again using the synthesized voice. Private home telephone test method.
