This is the IP address of the configured TFTP server. If it is non-zero or not
blank, the HandyTone ATA will attempt to retrieve new configuration file or
new code image from the specified TFTP server at boot time. It will make up to
3 attempts before timeout and then it will start the boot process using the
existing code image in the Flash memory. If a TFTP server is configured and a
new code image is retrieved, the new downloaded image will be verified and
then saved into the Flash memory.
