Cisco 1841 ADSL / SHDSL configuration

attila.bogar · ‎11-06-2008

Hi,

I have a Cisco 1841 router with the following modules installed:

HWIC-1ADSL

HWIC-2SHDSL

For some reason the HWIC-2SHDSL module in slot 1 is not supported / disabled in this slot according to the 'show diag' command. (Please see attached show_diag.txt)

From the configuration manual the minimum Cisco IOS Release should be version 12.4(11)XJ. The output from the 'show version' command outputs the following:

Cisco IOS Software, 1841 Software (C1841-BROADBAND-M), Version 12.4(4)T8, RELEASE SOFTWARE (fc3)

ROM: System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1)

My question is do I have the correct ISO version installed on the router? If I do have the correct version why when I run the command 'controller shdsl 1/0/0' do I get the following output?

router(config)#controller shdsl 1/0/0

^

% Invalid input detected at '^' marker.

Thanks in advance.

Hello Attila,

try to upgrade to

BROADBAND c1841-broadband-mz.124-22.T.bin

as per feature navigator

www.cisco.com/go/fn

searching for feature I found support for two to 4 wire SHDSL detection

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gt4wire.html#wp1027184

So this should support the SHDSL HWIC

current ios is clearly not able

Hope to help

Giuseppe

Thanks Giuseppe, I have updated the IOS and it now recognizes the SHDSL module.

Cheers,
