WIC-1DSU-T1-V2 does not show up on Cisco 2610

Unanswered Question
Feb 18th, 2008

We have a Cisco 2610 router which only handles one T1 right now. We wanted to add a second T1. So we got a new card WIC-1DSU-T1-V2 and plugged that in W1 slot.

When I run show diag I can see the card but it does not appear on the running configuration.

The other card: WIC-1DSU-T1 right now it is working just fine.

How can I use the WIC-1DSU-T1-V2 on this router?

Here it is what I get

After looking at some of the Cisco documentation I believe that the WIC-1DSU-T1-V2 is supported on 2600XM routers but not on the earlier 2600 routers. I am not sure that there is any way that you will be able to use that card in that router.

Here is a link to one of those documents:

Even though the docs states one thing, software advisory tools find software compatible with hardware the T1 v2 card is listed for the non XM 2610 router.. so you may be able to get it working either by Edison's suggestion or different IOS code.

When I read the original post and before I had dug into the question very much I had wondered about whether configuration of the controller was necessary and might be the solution. In the docs that I read through for WIC-1DSU-T1 and WIC-1DSU-T1-V2 they do not show any separate configuration of the controller. I am not optimistic that this will solve the problem.

The docs for WIC-1DSU-T1-V2 indicate that it was supported in 12.3 mainline code. And the code that you are running is a bit into the 12.3 series. You could try a more recent version of code and perhaps support was extended in later versions. It might be worth a try, but I am not optimistic that this will solve your problem either.

WIC-1DSU-T1-V2 is *not* supported on 2610 (non XM). Even though you see it in show diag, no matter what IOS you try, it would still not show the interface in show version or the running config.

(Also, no special configuration is required on the platforms where its supported.)
