Cisco 877 ADSL firmware update?

paradigm · 13 Jul 2010 at 18:40

I'm trying to update the Alcatel firmware on my 877.

It's running 124-22T Advanced IP Services IOS, and the embedded ADSL firmware is v3.0.14.

I was under the impression that all I needed to do was to copy the new .bin via TFTP to flash:, and a reload would then take care of loading the firmware on boot.

However, even though a dir flash: reports that the file has indeed been successfully loaded (adsl_alc_20190_4.0.018.bin), after as many reloads as I like, viewing the output of sh dsl int atm0 | begin Init FW still shows me that I'm running on the embedded v3.0.14 bin

Anything I should be doing differently?

It's not a major problem, the old firmware syncs at 7092kbps and I appear to have a profile of 6Mb, but I'd like to adjust the dsl noise-margin, which appears to not be a feature of the firmware I currently have. Again, it's not a huge issue as it's only my backup line (primary being VM 50Mb cable).

Tried renaming it to adsl_alc_20190.bin, i.e. without the version number?
That's what I've set it to and it picks it up without anything in the config.

I'm literally in the process of trying ALC_4.0.018.bin, it's reloading now, will see what happens.

I've just checked mine in fact:

FW Source: embedded
stargate uptime is 44 weeks, 6 days, 22 hours, 9 minutes

Whoops! It definitely was enabled when I had it hooked up to Zen :eek:

Ok, that worked, cheers Tolien, one question though...

Should I now have dsl noise-margin [-3 - 3] available as a command on int ATM0?

If so, it's still not right, as I'm still being told it's an invalid input.

EDIT: Just seen your post. With mine named adsl_amr_20190.bin, i've definitely got Source: External now.

I don't recall ever having that option on my 877.

Have you been able to tweak your SNR at all on your 877?

tolien · 13 Jul 2010 at 19:55

Other than via Be's portal, no.

Whacking in the command service internal in global configuration mode then adds a lot of features to the dsl command on interface ATM0.

Code:

paradigital(config-if)#dsl ?

bitswap              Bitswap Feature
enable-training-log  Enable the fw training log for Showtime and failure cases
gain-setting         ADSL programmable gain setting
lom                  Loss Of Margin watch counter for line retrain
max-tone-bits        Set maximum bits per tone limit
noise-margin         Set noise margin offset
operating-mode       Auto or specific ADSL mode
power-cutback        Noise Threshold for Power CutBack
sync                 ADSL sync preferences

When I had an 877 the DSL noisemargin tweak failed to do anything.

I'll give it a go on mine tonight and see what happens
