Chapter 7 Upgrading the Cisco ATA Signaling Image

Upgrading the Signaling Image Manually

•tftp_server_ip is the TFTP server that contains the latest signaling image file.

•image_id is a unique 32-bit integer that differs with each upgrade. You can determine this 32-bit integer value by using the build date on the image file name and prepending it with "0x". For example, if the image_file_name is ata186-v2-14-020514a.kxz, then the build date is 020508a, and the image_id is 0x020508a).

•image_file_name is the firmware upgrade-image file name. The image_file_name format is: ata186-v{M}-{N}-{yymmdd}{a-f}{ext}

–- M is the major version number

–- N is the minor version number (always two digits)

–- yymmdd is a two-digit year, two-digit month, and two-digit day

–- a-fis the build letter (- yymmdd and a-ftogether form the build date of the image)

–- ext must be ".kxz" for upgrading from version 2.11 and below, and can be ".zup" for upgrading from version 2.12 and up for the Cisco ATA186, but it must be ".zup" for upgrading the Cisco ATA188.

Process

Whenever the Cisco ATA administrator stores a new signaling image (denoted by a change to the image_id), the Cisco ATA upgrades its firmware with the new image_file. To contact the TFTP server, the Cisco ATA uses the TFTP server IP address that is contained within the value of the upgradecode parameter.

Example

The upgradecode parameter value could be:

upgradecode:3,0x301,0x0400,0x0200,192.168.2.170,69,0x020723a,ata186-v2-15-020 723a.zup

This instructs the Cisco ATA to upgrade its firmware to ata186-v2-15-020723a.zup by downloading the ata186-v2-15-020723a.zup file from the TFTP server IP address of 192.168.2.170. This download occurs after the Cisco ATA downloads its configuration file that contains the directive from the upgradecode parameter. Also, the upgrade occurs only if the internally cached image_id in Cisco ATA is different from the value 0x020723a.

Upgrading the Signaling Image Manually

This section describes how to manually upgrade the Cisco ATA with the most recent signaling image. The executable file that you need is called ata186us.exe, and is bundled in the Cisco ATA release-software zip file.
