DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the test method for a line device according to the present invention will be described below. In this embodiment, as shown in FIG. 4, the testing method of the line device includes a computer 30, which is a common host device, two line devices 31, 32 connected to the computer 30, and the line device 31, It is made up of a device composed of an exchange 35 connecting lines 33 and 34 connected to 32. Here, the line and the exchange may not be public lines but may be a pseudo exchange having the same function as the exchange as long as both line devices are actually connected.

Here, the computer 30 which is a higher-level device
Is a push button data output unit 36 that outputs a digital signal designating an arbitrary push button signal to the line devices 31 and 32, and an input that stores a digital signal designating the content of the push button signal from the line devices 31 and 32. The functions of the push button data storage unit 37 and the comparison unit 38 for comparing whether the push button data designated by the push button data output unit 36 and the push button data stored by the input push button data storage unit 37 are the same. Have.

Further, the computer 30 has the line device 3
An input audio data storage unit 39 that stores a digital signal that specifies the content of the audio signal from the input audio data 1, 32, and an output audio data output unit 40 that outputs the same audio data as the audio data stored in the input audio data storage unit 39. And have as its function. Here, the output voice data output unit 40
At the time of use other than the test, for example, when operating as a facsimile media service apparatus, it is possible to output arbitrary voice data, and at the time of the test, it is the same as the voice data stored in the input voice data storage section 39 as the data. The audio data of is output.

The two line devices 31 and 32 have the same configuration, and analyze the voice signal which is an analog signal from the lines 33 and 34 and output it as a digital signal to the computer 30, and at the same time, the computer 30. A voice signal is created based on the digital signal from the voice input / output device 41, 43 for outputting the voice signal to the line, and the voice signal from the lines 33, 34 is analyzed as a push button signal, and a digital signal is output to the computer. There is provided a push button signal input / output device which outputs the push button signal to the lines 33 and 34 while outputting the push button signal based on the digital signal input from the computer 30.

In this embodiment, under the control of the computer 30, the line device tests of the above-mentioned second means are automatically carried out successively in this state. The operation of the line device test method according to this embodiment will be described below. FIG. 5 is a flow chart showing the operation of the line device test method according to the present embodiment. First, the target line is connected (SA1), and the push button data output section of the computer 30 creates push button digital data to be output (SA).
2). This is sent to, for example, the push button signal input / output device 42 of the line device 31, and the push button signal input / output device 42 creates a push button signal which is an audio signal based on this, and outputs it to the line (SA3). ).

This push button signal is input to the other line device 34 via the line 33, the exchange 35 and the line 34 (SA5), and converted into digital data as a voice signal by the voice signal input / output device 43 (SA6). ), Is sent to the computer 30, and is stored in the input voice data storage unit 39. The output voice data output unit 40 creates the same data as the input voice data, that is, the data designating the same voice output as the input voice signal (SA7), and outputs it to the voice signal input / output device 43 of the line device 32. Then, the audio signal input / output device 43 creates an audio signal based on this data (SA8) and outputs it to the line (SA9).

In the present invention, in this case, the signal input from the line 34 to the line device 32 is a push button signal, but when the signal is input to the line device 32 (SA5),
Until output (SA9), this signal is not treated as a push button signal, but is treated as normal voice. Therefore, if the audio signal input / output device is normal, the same audio signal as the input audio signal and the same push button signal as the input push button signal are output. On the other hand, if the voice signal input / output device is abnormal, a voice signal different from the input voice signal, that is, a voice signal that is not recognized as a push button signal at all, or a push button signal different from the input push button signal is output. .

Then, this voice signal is input to the first line device 33 through the line 34, the exchange 35, and the line 33, and is converted into digital data as a push button signal by the push button signal input / output device 42 (SA10).
It At this time, as described above, when this voice signal is not recognized as a push button signal, it is processed as an abnormality (SA14). When this signal is a push button signal, this digital data is sent to the computer 30, and the comparison unit 38 determines whether or not it matches the push button digital data output by the push button data output unit 36 (SA12, SA13). If they match, they are processed normally (SA14), and if they do not match, they are processed as abnormal (SA15).

Until this test is carried out for all combinations of line devices, a series of these processes (SA1 to S1)
A15) is performed (SA16). In this example, the line device 31
The line device 32 is replaced with the line device 32, a push button signal is sent from the push button signal input / output device 44 of the line device 32, and the voice signal input / output device 41 of the line device 31 is tested.

Therefore, according to the present embodiment, when the push button data match in the comparing section 38, it can be determined that the series of push button signal input / output devices, lines, and voice signal input / output devices are normal. Even when an abnormality occurs, if it is confirmed in advance that the push button signal input / output device and the line are normal, it can be determined that the voice signal input / output device is abnormal.

Here, the voice input / output device does not necessarily handle only the voice signal corresponding to the push button signal, but practically, it does not matter if it is normal within the range of the push button signal. Therefore, according to the present embodiment, the test of the voice signal input / output device of the line device can be automatically performed, and the test can be performed on the line. At the same time, it can be confirmed that the push button signal input / output device is normal.

In the above embodiment, the case where the test is alternately performed on the two line devices has been described, but the present invention is not limited to this, and the test of the voice input / output device is performed by the voice input / output device. If it is to automatically input the push button signal to and determine whether the returned push button signal is the same as the input one, the number of the target,
It goes without saying that the present invention can be applied regardless of the configuration of the line device.

[0027]

Therefore, according to the present invention, the voice signal which is an analog signal from the line is connected to the host device and the line is analyzed and output to the host device as a digital signal. A test method of a line device having a voice input / output device for creating a voice signal based on a signal and outputting the voice signal through a line is described by inputting a push button signal to the line device through the line. The voice input / output device analyzes the input push button signal as a voice signal and outputs it as a digital signal to the host device.
The host device 1 outputs a digital signal specifying the push button signal as a voice signal to the line device 4 based on the input digital signal, and the voice input / output device of the line device 4 outputs the voice signal created from this digital signal. Since the audio signal is output via the line 2 and the input push button signal is compared as the output push button signal, the audio signal input / output device of the line device can be automatically tested. In addition, the audio signal input / output device and the push button signal input / output device can be automatically performed at the same time.
