Abstract

PROBLEM TO BE SOLVED: To provide an information processor capable of immediately recognizing the version number of a control program file downloaded to respective substrates without incorporating the respective substrates on a system and recognizing the version number of the control program file in a state of a substrate single body. SOLUTION: When a SW 20 for version number display on the substrate of a speech path system device 1 is depressed, power is supplied from a backup power source 19 only to a backup power operation part 12 and a power ON reset state is attained. A μP 13 reads a reset register inside a peripheral circuit 17, and when an LED display bit is raised, reads the version number of the downloaded control program file inside a fixed address inside an EEPROM 15 and displays the version number of the control program file at an LED 18 for the version number display.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus, a method of displaying high-change frequency information used therefor, and a recording medium on which a control program is recorded. To display the version number of the control program.

[0002]

2. Description of the Related Art Conventionally, in a switching system, a control program file for operating a μP (microprocessor) on a board of a communication path device is constituted by a control system device and a communication channel device. From the EEPROM on the board (Electrically
Erasable and Programmable
e Read Only Memory).

In this system, in order to display the version number of a downloaded control program, a corresponding board is mounted on the system, and a control terminal, a system bus, and an initial line of each board of a communication path unit are transmitted from a console terminal. After setting, it is necessary to issue a version number reading order to the board of the communication path system.

[0004]

In the above-mentioned conventional method for displaying the version number of the control program, the version number reading order is issued to the board of the communication path apparatus, so that there is no problem when the system is initially started up. However, when a board needs to be replaced due to a problem such as a failure, when a replacement board is brought in, a board with a control program of a version that is not compatible with the system (generally an old version etc.) is mounted on the system. The problem is that it is.

If a board on which a control program of a version number that does not match the system is mounted is mounted, the system may malfunction. In the case of downloading in a system operation state, it takes time to prepare for transferring a download file from a server.

In the case of substrate exchange, the exchange system is operated as a single system, so that the system must be operated as quickly as possible, and the system must be brought into a normal redundant operation state. You. The manufacturer prepares a spare board, but since it is a control program file to be downloaded, it is not easy to check the version number installed in it, and if the board is not incorporated into the system once, There is a problem that the version number cannot be confirmed.

[0007] The control program file is usually downloaded and shipped by the manufacturer, but it is also sometimes downloaded at the office (customer side), and the version number cannot often be grasped. There is.

Therefore, an object of the present invention is to solve the above-mentioned problems and to immediately recognize the version number of a control program file downloaded to each board without incorporating each board into a system. An object of the present invention is to provide an information processing apparatus capable of recognizing the version number of a control program file in a single state, a high change frequency information display method used therein, and a recording medium recording the control program.

As described above, the version number of the control program file downloaded to each board can be immediately recognized without being incorporated in the system. The version number can be recognized. With this effect, it is not necessary to send a board with an incorrect version number mounted to a station or a customer and mount it, and incorporate the board into a system, thereby enabling a quick system startup.

In the above description, the operation at the time of downloading a control program has been described. However, the present invention can be applied to storage of a control program other than download.
When the control program file is not a download method, it is often stored in an EPROM or the like. EPR
In order to prevent erasure by ultraviolet rays when writing to the OM, it is common to seal the window of the EPROM and specify the version number.

However, even in this method, the EPR
Since the data in the OM cannot be guaranteed unless the confirmation after the writing is read by the system, a means for simply reading the version number as in the present invention is considered to be effective.

In addition, it is not possible to judge by looking only at the device like a downloaded control program file, and it is also applicable to information that is frequently changed. μP13
Is saved in the EEPROM 15 on the board, and if the number of failures of the board can be displayed by pressing a specific SW as in the above-described embodiment, the frequency of failure is high at a glance after the board is recovered due to the failure. It is useful for failure analysis such as identification of the board and identification of characteristics.
