Abstract

PURPOSE:To simplify and make the test accuracy by providing a voice generating means informing a test operating procedure of a subscriber telephone set to a test personnel in a natural language. CONSTITUTION:When a test control section 8 detects the connection of a subscriber line through the operation of a line supervisory relay 3, a control instruction is given to a voice generating section 7, the test operating procedure is given to a subscriber line in a natural language and informs it to the test operator. After the test is conducted, a test control section 8 gives a control instruction again, the voice generating section 7 uses the control instruction, gives the result of test to the subscriber line in a natural language to inform it to the test operator.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for testing a subscriber line including a subscriber telephone using a signal from the subscriber telephone. This relates to line testing equipment.

[Conventional technology]

Conventionally, this type of subscriber line testing device 20 has a specific number as shown in FIGS.
By dialing the specific number from , connection is established via the network 18 connected to the exchange common control section 19 in the space division exchange shown in Figure G3, or via the test link 21 in the time division exchange shown in Figure 4. It was to be done.

At this time, the line monitoring relay in the subscriber line testing device 20 operates, and the operation of this relay causes the test! 4. When the control circuit in the device d is activated and the test operator sequentially performs predetermined test operations from the subscriber telephone 1, the subscriber line testing device 20 performs an insulation test, a subscriber call-back test, and a buzz/signal test. Specified tests such as the test and dial pulse tests were conducted, and the test operator was notified of the quality of the results each time using an identification card.

[Problems to be solved]

In the conventional subscriber line testing equipment as described above, predetermined test operations are assumed, and the prerequisite test operations are performed in order.
There was a problem in that because the test was conducted in four different ways, one had to be familiar with the test or the predetermined test operation and the meaning of the identification sound.

The present invention solves the above-mentioned problems, and eliminates the need for test operators to carry operating procedure manuals and to be familiar with prescribed test operations and the meaning of identification documents, allowing them to easily and accurately conduct tests. The purpose is to provide a subscriber line testing device that can be implemented.

Solution to Problem c] In order to achieve the above-mentioned object of the present invention, the subscriber line testing device according to the present invention is connected to a subscriber telephone via an exchange network or a test link, and $
- Subscriber telephone gutter corresponding to telephone number 1? The subscriber circuit test equipment that performs each test, including the call test, is equipped with a voice generating means that notifies the test operator of the subscriber telephone in natural language of the operating procedure for the test of the telephone. .

〔Example〕

Next, an example j of the present invention will be explained based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a subscriber line testing equipment according to the present invention.

FIG. 2 is a block diagram of the voice producing section in the roundabout embodiment.

Tests in the present invention include insulation tests of subscriber lines including stuffing machines, O+ return tests, and pushbutton signals! 5C test, dial pulse test, etc.

In the figure, 1d is a subscriber's telephone, and this subscriber's telephone 1 is
are connected to input terminals 1a and lbK of the test device via a network or test link (not shown).

Insulation resistance test switching contact 9 from input terminals 1a and lb
It is connected to the audio supply line 2 via a and 9b. Input terminals 1a and lb are connected to a circuit monitoring relay 3km. Further, contacts 10a and lobs of a relay 10 are connected in parallel to the voice supply line 2 to prevent the voice supply line 2 from influencing the circuit monitoring relay 3VC during a dial pulse test. Said circuit monitoring &l! A contact 3a of the electric appliance 3 is connected to a dial pulse signal test section 6, and this dial pulse signal test section 6 is connected to a test control section 8. The test control section 8 also includes a line test and subscriber call-back section 4. Button signal test section 5.
A voice generator 7 is connected to notify test operation procedures and test results. The button signal test section 5 is connected to input terminals 1a and xbK via a DC blocking capacitor 11.

Next, to explain the operation of the above embodiment, first, when the test control section 8 detects that the subscriber line is connected due to the operation of the circuit monitoring relay 3, the test control section 8 transmits the sound generation section 7. A control command is issued, and according to the control command, the voice generating unit 7 transmits the test operation procedure in natural language to the subscriber line.
Notify the test operator 0 Then, when the test operator performs the notified operation, the subscriber line testing device performs a test based on the operation. After that, the test control section 8
A control command is issued again, and the voice generating section 7Fi transmits the test result in natural language to the subscriber line according to the control command, and notifies the test operator. In this way, an insulation test, a call-back test, a button signal test, a dial pulse test, etc. can be carried out in sequence. Here, the call signal used for the call-back test is supplied from outside.

- Takara Fue 9 (branch) f 鋪P 嵵 This is a block diagram of the voice generating section 7, which includes a read-only memory element 13 for accumulating voice data, and a read-only memory that is read-only by the control command of the test control section 8. It is composed of an address control section 14 for controlling read data of the element 13, a data parallel-to-serial conversion section 15, a digital-to-analog conversion section 16, and an audio output coil 17.

The test procedure for subscriber line testing equipment and the voice data of the test results are based on pulse code modulation (PCM) of natural language voice data.
) etc., the analog data is converted into digital data, and the data is written into the read-only memory element 131C, differentiated by the address of the memory element. In addition, when the test control unit 8 of the subscriber line testing device transmits the address of the corresponding memory element to the voice generation unit 7 by a control command according to the test operation procedure or test result to be transmitted to the test operator, address control is performed. The unit 14 sequentially reads data stored in a certain area starting from the specified address. Since this data is stored in parallel on the memory element, the data is converted into serial by the parallel-to-serial converter 15. Furthermore, digital
The analog conversion section 16 converts the digital data from natural speech into synthesized speech, and the speech output coil 17 supplies the digital data to the outside.

〔Effect of the invention〕

As explained above, 1. According to the subscriber line testing device according to the present invention, voice generating means is provided for notifying the test operator of the subscriber telephone of the test operation procedure of the subscriber telephone in natural language. , test operators who conduct subscriber line tests do not need to carry operating procedure manuals or are familiar with the prescribed test operations and the meanings of identification tones, allowing them to conduct tests easily and accurately. This effect is achieved.
