Description

Description: TECHNICAL FIELD The present invention relates to a test method performed when a facsimile machine is installed or the like.

(Prior Art) When a facsimile apparatus is installed, a test of transmission and reception of facsimile signals is usually performed by a service person or the like. This test is performed at a specific receiving terminal, for example, at a service center to which the service person belongs.

 A test method for normal transmission and reception will be described.

First, an original is facsimile-transmitted from a terminal (hereinafter, referred to as a terminal under test) in which a facsimile apparatus is installed to a service center or the like (hereinafter, referred to as a test terminal). The received document is printed out by a facsimile machine on the test terminal side that has received the document. The operator who determines that the received manuscript is the test manuscript is the telephone number of the terminal under test (usually written in the manuscript or received a telephone call in advance to send the test manuscript). ), And the received and recorded original is retransmitted from the facsimile apparatus on the test terminal side to the facsimile apparatus on the terminal under test side. The terminal under test can print out the retransmitted original and compare the transmitted original with the transmitted original to know the result of transmission / reception.

According to such a conventional test method, the test terminal requires human resources for the installation test, and the terminal under test waits for a service person or the like to obtain a test result. It is desired that the terminal immediately retransmits the received document. Therefore, the test terminal has a problem that the operator must constantly monitor the facsimile machine.

(Problem to be Solved by the Invention) The present invention has been made in order to solve the above-mentioned problems, and a test method for transmitting and receiving a test between a terminal under test and a test terminal has been described. It is an object of the present invention to provide a test method that does not require manual operation in a computer.

(Means for Solving the Problems) The present invention relates to a facsimile test method for performing transmission / reception for a test between a terminal under test and a test terminal, wherein an image as test data is transmitted from the terminal under test to the test terminal. Receiving the signal, the test terminal stores the received telephone number information and the image signal, then automatically dials the terminal under test based on the stored telephone number information, and then receives the stored image signal. Is what you do.

(Embodiment) FIG. 2 is a schematic configuration diagram for explaining a facsimile apparatus on the test terminal side applied to an embodiment of the facsimile test method of the present invention. In the figure, 1 is a line, 2 is a line control unit, 3 is a transmission control unit, 4 is an automatic dialing device, 5 is a ROM for storing programs and fixed information, 6 is a RAM, 7 is an information storage unit, and 8 is a document reading unit. Unit, 9 is a recording unit, 10 is an operation unit, 11
Denotes a display unit, and 12 denotes a main control unit (CPU) that controls the entire control.

The information storage unit 7 can store document data, which is an image signal received from the line 1 via the line control unit 2 and the transmission control unit 3. The document data stored in the information storage unit 7 in the case of memory reception can be printed out according to an instruction from the operation unit 10.

The document data read by the document reading unit is sent out to the line 1 simultaneously with the reading or after being stored in the information storage unit 7 via the transmission control unit 3 and the line control unit 2. The storage of the document data in the information storage unit 7 may be an encoded signal or an appropriate signal form such as a bit data signal.

In addition, the facsimile apparatus is configured such that a normal transmission / reception mode and a test mode for a communication test described later can be selected by setting of the operation unit 10.

When the facsimile apparatus is set to the test mode, the received original data is stored in the information storage unit 7, and the stored originals are transmitted to the line 1 via the transmission control unit 3 and the line control unit 2. can do. The RAM 6 may be used as the information storage unit 7. In addition, RAM6
It stores the telephone number of the caller who is the recipient. RAM6
Can be dialed by the automatic dialing device 4 in accordance with an instruction from the CPU 12.

FIG. 1 is a flowchart for explaining one embodiment of the facsimile test method of the present invention. The test terminal will be described as using the facsimile apparatus described with reference to FIG.

The flow starts when a facsimile signal is received. In Step 1, if the facsimile apparatus is set to the test mode, the telephone number of the terminal under test is detected from the telephone number or the like registered in the TSI signal received in Step 2, and this is stored in the RAM 6 in Step 3. Then, the process proceeds to Step 4, where the document data transmitted by the facsimile procedure is stored in the information storage unit 7, so-called memory reception is performed, the reception operation is completed, and the line is disconnected in Step 5. After the line is disconnected, the facsimile apparatus of the terminal under test is in a standby state since the transmission has been completed. In Step 6, the facsimile machine of the test terminal enters the transmission operation, re-acquires the line, reads the telephone number from the RAM 6 in Step 7, and automatically dials the telephone number of the terminal under test by the automatic dialing device 4. After connecting the line, Step8
In accordance with the facsimile procedure, the original data stored in the information storage unit 7 from the terminal under test is transmitted back by so-called memory transmission. The terminal under test can print out the received original and compare the transmitted original with the transmitted original to test the transmission / reception state.

If no telephone number is detected in Step 2, the flow goes to Step 8 to disconnect the line and end the flow.

When the facsimile apparatus is set to the normal transmission / reception mode, after receiving an incoming call, the process proceeds from Step 1 to Step 9 to perform reception in the normal mode.

If necessary, the document data received by the test terminal may be printed out. By comparing the transmitted document and the received document at the terminal under test, the transmission state and the reception state can be known.

Also, in the above-described embodiment, the original read by the facsimile apparatus at the terminal under test was used as the image signal.
The test data may be stored in the RAM of the facsimile apparatus in advance and used as a transmission original for the test. In this case, since the pattern of the document data is known in advance, the comparison between the transmitted and received document data can be performed on a bit basis. Automatic comparison is also easy. Of course, the comparison can be performed at the test terminal, and the result can be transmitted to the terminal under test.

In the case of a communication test, the terminal under test may also transmit an identification signal indicating a communication test.
The identification signal is detected by the facsimile apparatus of the test terminal. When the identification signal is received by the test terminal, the facsimile apparatus is automatically set to the test mode. When the identification signal is not received, it is determined that normal facsimile reception is performed, and the normal reception mode is automatically set. You. In this mode, only normal reception is performed without shifting to return transmission.

(Effects of the Invention) As is clear from the above description, according to the present invention, there is an effect that the communication test of the facsimile apparatus on the terminal under test side can be performed unattended on the test terminal side.
