Abstract

PURPOSE: To rewrite an existing parameter when a normal operation is performed in a test and to easily restart an operation by the existing parameter when an abnormal operation is performed by performing an operation confirming test by a new parameter as holding the existing parameter when the operating parameter of an exchange is changed. CONSTITUTION: A maintenance interface part 14 is connected to a maintenance terminal 30 for setting/changing the operating parameter. A communication port part 11 consisting of plural input/output ports is connected to a port interface part 12. A main control part 13 contains the main functions of a processor, memory and a switch circuit, etc. A parameter storage part 20 consists of nonvolatile memory. and stores the operating parameter of the exchange 10. A reset switch 15 is a switch to instruct system reset by a manual operation, and a reset mode switch 16 is a switch to designate the operating parameter used in system reset. By employing such constitution, a danger due to the change of the operating parameter is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange for setting / changing operating parameters and starting up a system from a maintenance interface, and more particularly to a mechanism for changing the parameters of the exchange by changing the network configuration.

[0002]

2. Description of the Related Art Generally, in a conventional exchange, in order to change the network configuration, it is necessary to rewrite the existing operating parameters, and if there is a problem, to restore the original configuration, set the existing parameters. I had to do it again.

[0003]

Therefore, in the conventional technique, when the parameters of the exchange are changed in accordance with the change of the network configuration, an abnormality occurs due to the problem of the changed part of the terminal or the exchange, and the original network is changed. When the system is returned to the configuration, it takes time to reset the parameters, and there is a problem that the existing part is greatly affected.

[0004]

In order to solve such a problem, the present invention stores an operation parameter for a test in an exchange in which an operation parameter is set / changed and a system is started up from a maintenance interface section. A temporary definition storage unit, a user definition storage unit that stores normal operation parameters, a temporary registration command unit that stores the operation parameters in the temporary definition storage unit, and a system using the operation parameters stored in the temporary definition storage unit The test reset command means for starting up and the main registration command means for storing the operation parameters stored in the temporary definition storage unit in the user definition storage unit are provided.

[0005]

According to the present invention, it is possible to perform a test operation confirmation with a new parameter while keeping the existing parameter. If the test operates normally, the existing parameters are overwritten with new parameters. If there is an abnormal operation, the operation with the existing parameters can be easily restarted.

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows an example of the exchange of the present invention. This exchange 10 has a port interface unit 12, a main control unit 13, a maintenance interface unit 14, a reset switch 15, a remote mode switch 16, and a parameter storage unit 20.

A maintenance terminal 30 for setting / changing operation parameters is connected to the maintenance interface section 14 to perform a connecting operation with the maintenance terminal 30. A communication port unit 11 including a plurality of input / output ports is connected to the port interface unit 12. The main control unit 13 includes main functions of the exchange such as a processor, a memory, and a switch circuit. The parameter storage unit 20 is composed of a non-volatile memory and stores operation parameters of the exchange 10. The reset switch 15 is a switch for manually instructing the system reset, and the reset mode switch 16 is a switch for designating an operation parameter used when the system is reset.

The parameter storage unit 20, as shown in FIG. 2, has a default value area 21, a user-defined area 22, and a temporary definition area 2.
Consists of three. In the default value area 21, the default values of the operation parameters are stored when the exchange 10 is manufactured, and cannot be rewritten by the user. The operation parameters used by the actual user are stored in the user-defined area 22. In the temporary definition area 23, test operation parameters are stored. One of the operation parameters stored in the default value area 21 and the user-defined area 22 is used according to the designation of the reset mode switch 16 when the system is reset. The operation parameters stored in the temporary definition area 23 are used only at the time of reset by the test reset command from the maintenance terminal 30.

Next, the procedure for changing the operation parameters and confirming the operation of the exchange 10 will be described with reference to the flowchart of FIG. The operation parameter with the new configuration is created by the maintenance terminal 30, and the temporary registration command is input from the maintenance terminal 30. Upon receiving the temporary registration command, the maintenance interface unit 14 notifies the main control unit 13, and the main control unit 13 stores the operation parameter in the temporary definition area 23. A test reset command is input from the maintenance terminal 30 in order to perform an operation test using the temporarily registered operation parameters (when Yes in step S1 of FIG. 3). The maintenance interface unit 14 is
When receiving the test reset command, the main control unit 13 is notified and the main control unit 13 performs the reset process. In the start-up process by the test reset, the start-up process is executed by using the operation parameter of the temporary definition area 23 (step S2). The switch is now ready to operate with the new operating parameters and is tested for operation with the new configuration.

If the operation test confirms the normal operation, the main registration command is input from the maintenance terminal 30. Maintenance interface unit 14 that received the main registration command
Notifies the main control unit 13, and the main control unit 13 notifies the temporary definition area 2
The operation parameters stored in No. 3 are stored in the user-defined area 22. During the execution of this main registration command, the operation of the exchange 10 is still continued. If an abnormal situation occurs in the operation test, the reset mode switch 16 is set to the user-defined side (No in step S3), and the reset switch 15 starts up with the operation parameter in the user-defined area 22 ( In step S4), the operation in the conventional network configuration becomes possible immediately. When the reset mode switch 16 is set to the default value side (Yes in step S3), the startup is performed using the default value parameter stored in the default value area 21 (step S5).
The tentative definition area 23 is a non-volatile memory, and the operation parameters at the time of the operation test remain even after returning to the previous configuration, which can be useful for elucidating the cause.

[0011]

As described above, according to the present invention, when an abnormality occurs due to the problem of the changed part of the terminal or the exchange when the parameters of the exchange are changed due to the change of the network configuration, the conventional It is possible to immediately return to the network configuration, operate the network in the previous configuration, and reduce the risk associated with network modification work.
