Maintenance Instruction ASB 150 02 > Remote Upgrading Of The Central Software

## Creating the Output File

The first step is to create an output file that shall be loaded into the exchange. Refer to the read me file giving details of the version of the software to be upgraded to and compare it with the program version installed in the PBX to be updated. It is important to know your market version to perform the upgrade for details refer to the “Ordering Information” (131 62-1x/ASB150 02) or the index of the software e.g. LZY 203 2230/x. The x states the market version needed to create the upload file.

Execute the 32 bit console application program chkdiff.exe in a DOS prompt. The program chkdiff.exe generates the file which is used for uploading the new SW-version. This application verifies which parts of the SW has been changed, determines the differences between the two SW-versions and creates an output file (*.txt). The file is a specially coded (containing line number, checksum, ...) but must not be opened by any tool (e.g. editor) as in this case the data may be corrupted.

The file denominations used for remote upgrading are explained in the following:

##### Link version

For this procedure it is very important to have the correct link version. This could present a problem in existing (running) SW-versions in a PBX. To find this value enter RASC. Menu maintenance -> HW/SW
-> CPU. Here the LZY 203 223x/x R1A the highest link version number is the valid number to be used and entered in the field of the software version currently in the PXB.

The link version can be read out using RASC. Check the LZY information with link version of the PROMS. The highest value is the correct link version or by reading the information in the PROM me-file.

After executing chkdiff.exe and select whether a standard or full upgrade is needed and enter the data accordingly.

#### Standard upgrade

This standard upgrade is the common upgrade for the ASB 150 02 exchange. Choosing this option keeps the transmission time as short as possible. The chkdiff.exe creates a file comprising only the differences between the existing software in the exchange and the new software to which it should be upgraded to.

Enter the requested values in the fields above. The operation is terminated stating that the output file e.g. r10 1 A_r10 1 B.txt was generated.

As an alternative it is possible to execute the chkdiff.exe and add the upgrading parameters in the command line such as:

    chkdiff [<old parameters>] <new parameters>

- for standard upgrade e.g.:

    	chkdiff r10 1 A r10 1 B

- for full upgrade e.g.:

    	chkdiff r10 1 B

#### Full upgrade

If the remote PBX has a software that requires a full upgrade then enter the letter "b". In this case the chkdiff.exe program executes a full software upgrade file. This results in the largest file size and therefore takes the longest time to transmit.

Enter the requested values in the fields above. The operation is terminated stating that the output file e.g. Blank_r101B.txt was generated.
