JPH0646132A - Fault display system for terminal equipment - Google Patents

Abstract

PURPOSE:To notify the kind of the fault of receiving information from an exchange to the user of an terminal equipment. CONSTITUTION:The terminal equipment 1 receives a command from the exchange by a command transmission/reception part 14 and a central control part 11 executes a command fault detection processing. The central control part 11 reads-out the command length and the command ID of the command received by the command transmission/reception part 14 to constantly check the normality of the command. At the time of detecting the presence of abnormality in the received command, a storage part 12 stores the occurrence of the fault in the command transmission/ reception part 14, ID of the abnormal command and the abnormal state of command length abnormality, etc. Furthermore, a fault analytic processing is started. In the command fault analytic processing, the central control part 11 reads the occurrence of the fault in the command transmission/reception part 14, ID of the abnormal command and the abnormal state from the storage part 12, reads the message of the content of the fault stored in the storage part 12 and displays it on a display part 13. Furthermore, the central control part 11 starts a fault restoration requirement processing and informs the content of the fault to the fault restoration requirement processing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device failure display system, and more particularly to a terminal device failure display system connected to an exchange through a communication line.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a failure display system for a terminal device of this type has a command transmission / reception section 23 for receiving a command from a communication line and a user for notifying that a failure has occurred in the received command. And a central control unit 21 for controlling the entire terminal device 2.

In the terminal device 2, the command transmitting / receiving unit 23 receives a command from the exchange through the communication line, and the central control unit 21 reads the command length and the command ID of the command received by the command transmitting / receiving unit 23, Always check for normality. If the command transmission / reception unit 23 detects that the received command is abnormal, the central control unit 21 recognizes that the received command has a fault and lights the lamp 22 to indicate that the fault has occurred. Notify the user that a failure has occurred.

Further, the central control unit 21 clears the received data of the command transmitting / receiving unit 23 and requests the exchange to retransmit the command. When the central control unit 21 finishes processing the command resend request, it turns off the lamp 22 and finishes the processing.

[0005]

This conventional terminal device failure display system only turns on a lamp indicating that a failure has occurred when a failure in a received command is detected. There was a problem that the user did not know what kind of failure occurred.

[0006]

SUMMARY OF THE INVENTION A failure display system for a terminal device according to the present invention is a terminal device connected to an exchange through a communication line, and transmitting and receiving means for transmitting and receiving information to and from the exchange, and the received information. Failure detection means for detecting a failure in the above, first storage means for storing the ID of the detected failure, recovery request means for requesting recovery of the failure, and failure analysis means for analyzing the failure detected from the ID And a second storage means for storing a message of a predetermined failure content for each of the plurality of failures, and a display means for displaying the detected failure content message.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a terminal device to which an embodiment of the present invention is applied, FIG. 2 is a flow chart showing a processing procedure in the case of command failure detection of a central control unit in this application example, and FIG. 3 is this application example. 5 is a flowchart showing a processing procedure in the case of command failure analysis of the central control unit in FIG.

In FIG. 1, the terminal device 1 of the present application example receives a command transmitted from an exchange (not shown) via a communication line, and a command transmitting / receiving unit 14 for requesting retransmission of the command, and a received command A storage unit 12 that stores a message of a predetermined failure content for each of the failure ID and a plurality of command failures, and a display unit 13 that displays a message of the content of the command failure.
A central control unit 11 that controls the entire terminal device 1 of this application example is configured.

Next, the operation of this application example will be described with reference to FIGS. 1, 2 and 3.

In the terminal device 1, the command transmitting / receiving unit 14 receives the command from the exchange, and the central control unit 11 executes the command failure detecting process shown in FIG.

The central control unit 11 reads out the command length and command ID of the command received by the command transmitting / receiving unit 14, and constantly checks the normality of the command (S1).
If it is detected that the received command is abnormal, the failure of the command transmitting / receiving unit 14, the abnormal condition such as the ID of the abnormal command, the abnormal command length, etc. are stored in the storage unit 12 (S3).

Further, the central control unit 11 activates a failure analysis process.

In the command failure analysis processing 22, the central control unit 1 reads from the storage unit 12 that a failure has occurred in the command transmitting / receiving unit 14, the ID of the abnormal command, and the abnormal state (S11), and stores them in the storage unit 12. The message indicating the contents of the failure being performed is read and displayed on the display unit 13 (S12).
Further, the central control unit 11 activates the failure recovery request processing (S
13) The failure recovery request processing is notified of the details of the failure (S14).

In the failure recovery request processing, when the central control unit 11 recognizes that a failure has occurred in the command transmitting / receiving unit 14, it clears the received data and makes a request for retransmission from the command transmitting / receiving unit 14 to the exchange. Further, the failure message displayed on the display unit 13 is erased, and the process ends.

[0016]

As described above, according to the present invention, after the failure of the received information is detected, the content of the detected failure is displayed on the display unit so that the user can know what kind of failure has occurred. It has the effect of being able to.
