Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a facsimile device having an interface with a data communication terminal device (DTE).

[0002]

2. Description of the Related Art In recent years, a modem having a function of connecting a PC to a line for performing facsimile communication from an information processing terminal such as a personal computer (hereinafter, these are collectively referred to as a PC for simplicity) And facsimile machines have come to be used.

The above-mentioned modem, the above-mentioned facsimile machine and a PC
If an error occurs and the image transmission / reception fails when a facsimile communication is performed by connecting the two, the user can check the cause of the error by using the error message of the facsimile software on the PC or the error of the facsimile device. There was only a communication report.

[0004]

The communication between a data communication terminal equipment (DTE) such as a PC and a data circuit terminating equipment (DCE) such as a facsimile is performed by EIA / T.
It is realized by the command specified by IA.

In this case, generally, in DTE, facsimile software is run for communication. However, there is a problem that the facsimile software outputs only an error message when an error occurs, and it is difficult to know at what point in the communication the error occurred.

Further, in the communication result report of the conventional facsimile apparatus, the result of communication with the remote station is known, but D
The result of communication with TE is unknown.

It is an object of the present invention to provide a communication device capable of notifying detailed error contents when an error occurs when the DTE transmits / receives a facsimile through DCE.

[0008]

According to the present invention, the DTE is DC.
If an error occurs during fax transmission / reception via E, D that is connected to both the DTE and the remote station
The CE outputs the communication sequence between DTE-DCE and between DCE-remote station as an error result report.

[0009]

According to the present invention, the communication sequence between the DTE-DCE and the DCE-remote station is stored in the memory, and when the error occurs, the sequence is output so that a detailed error result report can be notified.

Further, according to user's designation, DTE-DC
A simple communication report can be notified by outputting only the communication sequence between E or only the communication sequence between DCE and the remote station.

Further, since the elapsed time from the start of communication to the generation of each communication signal can be recorded in parallel by the user's designation, a more detailed error result report can be notified.

1 is a block diagram showing the relationship between DTE and DCE in an embodiment of the present invention.

When sending facsimile data from the DTE 1 to the remote station 20, the DTE 1 sends the data to the DCE 10, and the DCE 10 issues a command to send to the remote station 20. The DCE 10 follows the command
The above data is transmitted as facsimile data to the remote station 20 through the telephone line.

On the contrary, when the DTE 1 receives the facsimile data from the remote station 20, when the remote station 20 transmits the data, the DTE 1 issues a command to the DCE 10 to send the data to the DTE 1 after receiving the data. By following the command, DCE10
DTE1 gets the facsimile.

FIG. 2 is a block diagram showing the structure of a facsimile apparatus according to an embodiment of the present invention.

As shown in the figure, an input / output interface 2 for exchanging data with the DTE 1, a recording unit 3 for outputting a facsimile image and an error result report, an operation unit 4 for performing key input, etc., and the entire apparatus. A control unit 5 for controlling, a modem 6 for modulating / demodulating transmitted / received data,
It has an LCD display unit 7 for displaying various information, a memory 8 for storing various data, and an NCU 9 for controlling connection of lines and the like.

FIG. 3 is a flow chart showing the procedure for selecting the error result report format.

First, the facsimile apparatus asks the operator whether or not to display the DTE-DCE communication sequence as an error result report (S2). Therefore, the operator selects either one with a predetermined key provided on the operation unit 4.

If the one not to be displayed is selected here, DC
Select the format to display only the communication sequence between E-remote station.

If the one to be displayed is selected, then
It is asked whether or not the communication sequence between the DCE and the remote station is also displayed (S3). Here, when the one not to be displayed is selected, the format only for displaying the communication sequence between DTE-DCE is selected.

If the display is selected, the DTE
-Select the format to be displayed between DCE and between DCE and remote station.

In this way, after determining between the devices outputting the communication sequence, the operator is asked whether or not to display the elapsed time from the start of communication (S4 to S6), and the operator further selects either one, and the format is selected. Is confirmed (S7 to S1
2).

FIG. 4 is a flow chart showing the operation of outputting the error result report.

After selecting the output format of the error result report as described above (S15), the controller 5
However, the input / output interface unit 2 or the modem 6
When the communication is performed via S (S16), the signal and the elapsed time from the communication start time are output to the memory 8 and stored (S16).
17, S18).

Next, it is determined whether the signal is an end signal (S19). If it is not the end signal, the process returns to S16. If it is an end signal, it is judged whether or not there is an error end (S20). If it is not an error end, the process ends without outputting the error result report.

If the error end has occurred, it is judged what the selected format of the error result report output is (S21 to S23), and the error result report is output from the recording section 3 in the selected format (S24 to S26). ),
The process ends (S27).

5 to 10 show the format 1 described above.
It is explanatory drawing which shows the example of the error result report from the format to the format 6.

In each figure, the items recorded in the DTE column are signals received by the DCE from the DTE.
The items recorded in the DCE column and having the arrow pointing to the left are signals sent from the DCE to the DTE, and the items pointing to the right are signals sent from the DCE to the remote station. Items recorded in the remote station column are signals received by the DCE from the remote station. From these, it is possible to know where and when the error occurred.

In the above description, the facsimile device as the data line terminating device has been described as an example, but the present invention can be applied to other communication devices.

[0030]

As described above, according to the present invention,
When an error occurs, the communication sequence is output as an error result report from the DCE, so that the cause of the error can be estimated.

Further, as described in claim 3, by additionally recording the time from the start of communication in the error result report, it becomes another clue to guessing the cause of the error. As a result, it is easy to repair the communication device when it breaks down.
