version] folder (named 1.1) within the Root folder of your FTP server
for that hardware version as well.
• The [software version] Folder: This folder sits inside the [hardware
version] folder - the folder name corresponds to the software version of
the IP Phone 1535 update files it contains. You will need a corresponding
[software version] folder inside the Root folder for every different software
version you wish to make available on your network. That is, if you have
an IP Phone 1535 software update with version 0.1.12, you will need to
have a corresponding 0.1.12 [software version] folder placed within the
[hardware version] folder corresponding to every hardware version of
IP Phone installed on your network. If you then also have an IP Phone
1535 software update with version number 0.1.13, you will need to add
a second [software version] folder (0.1.13) within the [hardware version]
folder corresponding to each IP Phone hardware version.
Example: You have an IP Phone 1535 with hardware version 1.1. In
setting up your FTP server for future updates to this IP Phone, you create a
[hardware version] folder inside the ROOT Directory, and name it 1.1. Your
IP Phone has a current software version of 0.1.12. You have two available
updates you wish to host, 0.1.13 and 0.1.14. For each of these software
update versions, create a [software version] folder within all [hardware
version] folder and place the update files in their respective folders.
The FTP software update files
There are three different kinds of files that are required for the firmware
update process:
• tar, tar2, tar3: These are the actual software upgrade files that contain
the firmware content itself.
• filecheck: the checksum file that confirms the integrity of the software
upgrade files.
• FirmwareUpdateRequest.acfg: This is the file that contains hardware
and software version numbers for the available firmware updates. The
FirmwareUpdateRequest.acfg file is what the IP Phone 1535 uses to
compare its current firmware version number against to determine if
there are updates available. Should the version number comparison
show that an update is available, this file directs the IP Phone to the
appropriate folder to initiate the download of the updated software.
Handling the FirmwareUpdateRequest.acfg file
The FirmwareUpdateRequest.acfg file is the most important file in the entire
software update process. When the IP Phone 1535 goes to the FTP server
to check for available updates, the FirmwareUpdateRequest.acfg file is
what it uses to learn if updates are available, and also the location of those
update files should a newer version be detected.
