IP Line Description, Installation and Maintenance
Download Protocol
The TFTP download mechanism is used in IP Line 4.5. The Master notifies
the Followers about changes to the status of the firmware file using a
broadcast on the TLAN network interface.
The UFTP download mechanism is used to download the IP Phone firmware
files.
Bootup Scenarios
If the Master is unable to retrieve a firmware file, the upgrade policy is set as
“Never”. When the upgrade policy is set to “Never”, the IP Phone’s firmware
version is not checked and the IP Phone registers with the firmware version
that is currently on the IP Phone.
If the Master card reboots, the Election process selects another Voice
Gateway Media Card as the Master. That Voice Gateway Media Card has all
firmware files in its memory. When the original Master card finishes
rebooting, it becomes the Master and does the normal Master start-up
procedure for retrieving the firmware files.
In a power-on situation, where all cards reboot together, the first card that is
elected Master retrieves the firmware files from the server.
CS 1000 systems
Default location of firmware files
For CS 1000 system configurations, the default storage location for the
firmware files is on the Signaling Server in the /u/fw directory. The firmware
file is downloaded to this directory, the file is selected in Element Manager,
and the Transmit button is clicked.
