Abstract

PURPOSE:To restore the state before the change without stopping the call processing operation by adding time information to restore commands to store them in order and taking out them in the reverse order. CONSTITUTION:When commands required for the change of station equipment data are inputted from an input/output terminal equipment 1, they are sent to a command execution and restore instructing part 3 through a command execution and restore request part 2. The instructing part 3 not only changes station equipment data but also causes a restore command generating and storying part 5 to generates a restore command and gives time information to it to store it. When time information of the command as the restore object is given from the device 1 to input a restore request command in the case of restore, the restore command is taken out of the storing part 5 through a restore command taking-out part 4. At this time, the taking-out part 4 takes out restore commands in the order opposite to the input order to send them to a restoring part 2. Thus, restoration is easily performed without stopping the call processing operation of an exchange.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a registered office equipment data recovery control system in an exchange.

[Conventional technology]

Conventionally, the registration of station equipment data in an exchange is input from an external terminal device. The recovery control method for the station equipment data input in this way is to either record the memory contents of the station equipment data in the exchange main body all at once in an external storage device according to commands instructed by the exchange maintenance operator, or to perform maintenance on the exchange in advance. There has been a method of reloading the memory contents recorded in the external storage device at a predetermined time instructed by the operator using a command instructed by the maintenance operator.

[Problem to be solved by the invention]

The above-mentioned conventional station equipment data recovery control method in the exchange equipment reads out the storage information recorded in advance on an external storage device and reconfigures the memory contents of the exchange equipment, so that even the station equipment data other than the one to be restored is returned to the state before the change. It has been restored,
Therefore, it was necessary to re-enter the command for changing station equipment data up to the point to be restored.

Also, if you want to reset the memory contents from an external storage device,
Since the memory contents of the station equipment data are set all at once from the external storage device, if there is a line in use when the station equipment data is restored, the memory contents for that line will be reset, and the status of that line will therefore be changed. The memory contents do not match the newly reset call processing information. In order to avoid this, while setting the memory contents, it is necessary to forcibly disconnect the line in use to temporarily stop the call processing operation, and to initialize the reset call processing information.

An object of the present invention is to restore the station equipment data to the state before the change without stopping the call processing operation by storing the recovery commands before the change so that the state before the change can be easily restored when the station equipment data is changed. The object of the present invention is to provide a possible station equipment data recovery control method.

[Means to solve the problem]

The station equipment data recovery control method of the present invention is such that when a command is input using an input/output device for the purpose of changing the station equipment data of an exchange, the station equipment data that has been changed by the command after the command is normally executed is recovery command generation means for restoring equipment data to a state before change; recovery command storage means for adding time information to the restoration commands and storing them in time order; It is comprised of a recovery command extraction means for extracting recovery commands in reverse order.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

FIG. 2 is an explanatory diagram showing an example of the recovery command of the present invention, and FIG. 3 is a flowchart diagram showing the operation of the station equipment data later control method according to the embodiment of the present invention.

FIG. 11 shows an input/output terminal device 1 that inputs change commands, a command execution/recovery request unit 2 that interfaces with the input/output terminal device 1, and a command information input by the input/output terminal device 1 and an instruction to execute the recovery command. Command execution/recovery instruction unit 3; recovery command generation/storage unit 5 that generates and stores recovery commands in order to restore station equipment data to the state before the change according to instructions from the command execution/recovery instruction unit 3; command execution/recovery unit 5; A recovery command extraction unit 4 extracts a recovery command from the recovery command generation/storage unit 5 in response to a recovery command from the input/output terminal device via the request unit 2.
and a station equipment data recovery control section 6 consisting of:

When equipment is added or changed in an exchange, it is necessary to change the station equipment data. Maintenance and operation operators use the input/output terminal bag W
When a command necessary to change the station equipment data from 1 to 1 is input, for example, command r Sent to 3. In the command execution/recovery instruction unit 3, the input/output terminal device 1
In addition to changing the station equipment data requested by the station equipment data, for example, in the event that a malfunction occurs in the exchange operation due to the addition or modification of the station equipment data, a restoration command is sent to the recovery command generation/storage unit 5 so that the state before the change can be easily restored. Send a generation request. The recovery command generation/storage unit 5 generates a recovery command for restoring the changed contents to the state before the change, adds time information held within the exchange to the generated recovery command, and stores it.

Also, lines that are in use when the station equipment data is restored are updated in the same way after waiting for the call to complete. Therefore, station equipment data can be updated without stopping the service.

The recovery operation of the station equipment data changed in this way will be explained.

To restore the station equipment data in the exchange, the exchange maintenance operator inputs the command to be restored from the final registration command "Y", for example, the command "Y", as shown in FIG. The time information given to each command up to "N" is "Δ month Δ day 16:
40. Δ month Δ day 9:30...X month x day 15
Step 20): Input the recovery request command by adding the same time information as 004.The command execution/recovery request unit 2 instructs the recovery command extraction unit 4 to extract the recovery command.Step 21) Extract the recovery command. The unit 4 extracts the recovery command stored in the command generation/storage unit 5, executes the command, and sends it to the recovery request unit 2.

At this time, the recovery command extraction unit 4 compares and collates the time given to the command when it entered the command with the time information given to the command recorded in the recovery command generation/storage unit 5, and extracts it in the reverse order of input order. It is sent to the command execution/recovery unit 2. That is, the time given to the command input and the time information given to the recovery command "N... ．ΔmonthΔday 9:
30. By comparing and collating Δ month Δ day 16:40 J, the recovery command “Y” is first extracted from the recovery command generation/storage unit 5 in the reverse order of the input order and sent to the command execution/recovery request unit 2 . The command execution/recovery request unit 2 displays the recovery command on the input/output terminal device 1, adds recovery instruction information, and sends the recovery command to the command execution/recovery instruction unit 3 (step 22). Command execution/
The recovery instruction unit 3 executes recovery of the station equipment data (step 23). At this time, since there is a recovery instruction, no recovery command generation work is performed.

When the execution of the first command "Y" is completed in this way, a request for the next command "X" is sent to the command execution/recovery request unit 2, and the next command is sent from the command execution/recovery request unit 2 to the recovery command extraction unit 4. Request the command r X J to be retrieved. In this way, the time of command input of the recovery instruction input from the input/output terminal device 1 is "x month x day 15: OO
The recovery commands up to J are sequentially extracted and executed through the command execution/recovery request unit 2.

Recovery time input from the input/output terminal device “x month x day 1
5:00. When the execution of all the commands rY, X...N up to Equipment data recovery processing ends.

〔Effect of the invention〕

As explained above, the present invention improves the call processing operation of the exchange by storing and executing the change contents as a command that can restore the state before the change each time the station equipment data is changed normally. This has the effect of making it easy to restore station equipment data without stopping the system.
