Telecom Italia Firmware Download Readme June 4, 2008 Firmware Version: 3.0.43 Cisco

1. Introduction

Firmware 3.0.43 was developed to solve a requirement for Telefonica, Spain and is to be used only by Telefonica. It is not intended to for general deployment of Cisco ADSL modems. 3.0.43 provides specific ADSL interoperability requirements as described in the following section.

2. Telefonica Requirement

Firmware 3.0.43 is based on firmware version 3.0.39 and has been extensively tested and certified by Telefonica, Spain. The default configuration restricts the use of upstream tones

3. Target Platforms Loading of the firmware file from flash separate from IOS is supported on all the Fixed ADSL Integrated Services Routers. Following is the list of platforms supported:

1 .Cisco 857 2. Cisco 876, Cisco 877 3. Cisco 1801, Cisco 1802 4. HWIC-1ADSL1, HWIC-1ADSLI, HWIC-ADSL-B/ST, HWIC-ADSLI-B/ST

4. Upgrade Instructions

1. Download the file and rename the file "adsl_alc_20190.bin". 2. Copy the firmware file to the flash: 3. For the new firmware to take effect, reboot the device. 4. The “show dsl interface atm 0” output gives the details of the firmware file in use

Example taken from the output of “Show dsl interface atm 0/0/0” command on an c1841 router running IOS 12.4(19.3)T1

Firmware file in flash is used Firmware file embedded in IOS is used

Init FW: init_AMR_4.0.013.bin Init FW: init_AMR-3.0.014_no_bist.bin Operation FW: AMR-4.0.013.bin Operation FW: AMR-3.0.014.bin FW Source: embedded FW Source: external

Note:

 The firmware file should not be renamed when being copied to the flash , Since the router looks for the presence of file named "adsl_alc_20190.bin" to initiate the flash upgrade process  If IOS is now able to find a valid firmware in the flash then it would always use that rather than the firmware embedded in IOS .If users want to use the embedded firmware, they have to ensure that there is no valid firmware file in flash.

5. Caveats

The following issues are fixed in the latest firmware 4.0.13
