Line coding on a 2600 w/T1 DSU card

[mfoc]

I've got a 2600 series router at a remote location and I need to find out what the line coding is set to on the DSU module that's in it. I've tried "sh int" and "sh controllers" - but I can't locate a line that identifies what I'm looking for.

Our VPN is down with that location and Qwest needs me to verify that it's set to B8ZS before they will continue troubleshooting on their end.

Any help would be greatly appreciated.

Try
cisco# sh controller t1

Tried that also. It doesn't do anything - just brings me back to the prompt.

Did you try a sh run?

Which slot and port is your controller card inserted in? Since 2600 is modular router you need

controller t1 0/0 - first slot first port
controller t1 0/1 - first slot second port
controller t1 1/0 - second slot first port

Why not directly configure it for linecode they are requesting? Use (on first slot, first port):

router(config)# controller t1 0/0
router(config-controller)# linecode b8zs

Here's what I found out.

This integrated WIC-1DSU-T1 module needs different commands than I'm used to.

The CSU/DSU shows up as interface serial 0/1

It also shows up as a controller, but needs to be configured using service-module commands.

Doing a sh service-module serial 0/1 shows info about the CSU/DSU, including the linecode.

To set the linecode, get into configure terminal mode
service module t1 linecode b8zs

Now, the coolest part of the whole thing is that after waiting 3 days to get my tech to that location (and spending $$$ paying him) because Qwest needed me to verify the linecode before they would continue troubleshooting on their side, the problem still exists...........
