Abstract

PURPOSE:To simplify the connection for the test by providing a call means calling a 2nd equipment being an equipment to be tested based on an off-hook signal of a 1st equipment on a line in conducting the test of the communication equipment such as a facsimile equipment, etc. CONSTITUTION:When an equipment FAX1a corresponding to the 1st equipment 1 hooks off, a call is detected in a line equipment 3a corresponding to a call means 30, a call tone is generated, a switch 30c of a call section 30b is operated and a call signal is sent to an equipment FAX2a corresponding to the 2nd equipment 2 from a call signal generator 31. When the call tone is repeated for a prescribed number in the equipment FAX2a, automatic reception state is obtained, the call tone is stopped to close lines. Thus, after the line level or the like is set to a desired set value by an attenuator 32 as required, prescribed transmission operation is conducted from the equipment FAX 1a to make transmission to the FAX2a thereby conducting the test of the reception of the FAX2a. Thus, the line equipment 3a with far inexpensive cost than the cost of an exchange is used to apply the line connection with the FAX2a by hooking off the FAX1a.

Description

[Detailed Description of the Invention] [Summary] This is a testing method for communication devices such as facsimile machines, in which a connection operation for testing is performed by providing a calling means for calling the device under test based on an off-hook signal on the line. Simplified.

[Industrial application field]

The present invention relates to a test method for testing communication devices by connecting them to a line, and particularly relates to a communication device test method that can simplify connection operations.

[Conventional technology]

In FIG. 3, FAXLa sends a FAX via exchange 3.
2a. FAX2a is the machine under test.

Therefore, when testing the receiving operation of the FAX 2a, line connection is performed in the following procedure.

■First, lift the handset of FAXla telephone 10.

(i.e. off-hook: 0ff-Hook) ■Exchange 3
When a call is detected, a dial tone is generated.

■Then, dial the other party's phone number (in this case, a temporary number for the exam).

(2) Then, the selection signal is identified in the exchange section 30a, the destination to be connected is determined, and a calling signal is sent from the calling signal generator 31 to the FAX 2a.

- When the FAX 2a repeats the ring tone a predetermined number of times, it automatically enters the receiving state, stops the ring tone, and connects the lines.

■Then, perform the specified sending operation from FAXla and send the fax.
2a, and the reception operation of FAX 2a is tested.

[Problem that the invention seeks to solve]

According to the above conventional method, since a normal exchange is used, (1) it is not only an expensive device, but also requires dialing the telephone number of the other party to connect the line, making the operation cumbersome.

■It is necessary to satisfy the usage conditions of the exchanger, and since the circuit is complete, it is difficult to add various circuit conditions from outside, and it is not possible to obtain test conditions that suit the actual situation. There is.

[Means for solving problems]

FIG. 1 is a block diagram of the principle of the present invention.

In the figure, 1 is a first device, 2 is a second device, and 30 is a calling means for calling the second device on the line based on an off-hook signal of the first device.

Therefore, when the first device goes off-hook, the second device is called up.

[Effect]

When the first device goes off-hook, the second device is called by the calling means 30 and a line connection is established without dialing, which greatly simplifies the operation.

〔Example〕

The present invention will be described in detail with reference to FIG.

The same symbols as in FIG. 3 indicate the same objects. Also, those corresponding to FIG. 1 are shown surrounded by one-dot chain lines.

In the figure, FAXla sends a FAX via line device 3a.
2a.

The line device 3a includes a calling section 30b and a calling signal generator 3.
It consists of 1.

The calling unit 30b includes a switch 30c that is activated by an off-hook signal from the FAXla, and has a function of starting the calling signal generator 31 when the switch 30c is activated.

The attenuator 32 is an attenuator configured so that quality such as line level can be set from the outside.

Since it has such a configuration and function, when performing a receiving operation test of the FAX 2a, line connection is performed in the following procedure.

■First, go off-hook on FAXla.

It works, and the call signal is sent to FAX 2 from the call signal generator 3.
Sent to a.

- When the FAX 2a repeats the ringing tone a predetermined number of times, it automatically enters the receiving state, stops the ringing tone, and connects the lines.

■Therefore, if necessary, set the line level etc. to the desired setting value using the attenuator 32, perform the specified transmission operation from FAXla, and send it to FAX2a.
The receiving operation is tested.

In this way, the line device 3a, which is warmer and cheaper than a switchboard, can be used to off-hook the FAXla.
Since it is possible to make a line connection with a, it is economical and the operation before the test is significantly simplified. Furthermore, since the quality of the line can be set, it is possible to perform tests that are appropriate for the usage conditions of the FAX machine.

Further, the circuit device 3a can be easily connected with various testing measurement devices and circuit conditions for margin testing at the same time.

Although the above example describes the case of testing a FAX device, the present invention can be similarly applied to other communication devices.

〔Effect of the invention〕

As described above, according to the present invention, (1) By off-hooking the first device, a line connection with the second device is automatically established using a low-cost device, which greatly simplifies the operation.

■Line quality settings can be easily configured.

There is an effect.
