WIC-1DSU-T1 compatibility with a Cisco 2821 Router platform.

My company is getting ready to purchase a new router to handle multiple T1 connections coming into our office.  We have over a dozen WIC-1DSU-T1 cards here and I was woundering if they were compatible.  I know Cisco has moved to the V2 version of this card and I'm not sure of backward compatibility.  Any help would be appreciated.

The older WIC's are not supported.  I don't know if they will even work.

Older "version 1" WIC 1 DSU's are fully compatible, even though they have been end-of-lifed.
You can use them as long as you like.

You should check with your Cisco rep before relying on these older WICs.  

While the older version is supported in general, in the link I referenced, Cisco specifically says it is NOT supported for the new 2800 platform you referenced in your question title (lrmoore - did you miss the 2821 reference or am I missing something here?)

I'm not saying it won't work, but if you have trouble, you may be on your own.

I've read and re-read that link and cannot find anywhere that references the 2800 series at all - neither specifically stating that it will, nor specifically that it will not be supported on that platform. Unless I'm getting too old and missed something - entirely possible..

I'll know for sure as soon as I get my 2811 in hand...I've got a couple older T1 WIC's laying around..

Blah!  I was running to a meeting and accidentally posted the wrong URL.  Here it is:

Title is Cisco 2800 Series Integrated Services Routers       Q&A

Look at table 3  answering the question "Which WICs are not supported on the Cisco 2800 Series?"

We've rolled out 240 2811's in our WAN upgrade, but didn't have to worry about the older WIC's since we were converting from Nortel and had no old equipment

I hope they do work for you guys but don't bet the enterprise on it..

I can't wait to see if that is true or not. I hope not..

Me, too.  I know there were architecture changes in the 2800 series, but it's annoying that they might force everyone to spend just a bit more to upgrade...

No one should still be trying to use the version 1 WIC's but just in case you are stumbling across this solution, they will not work in the new 2800 series routers. All modules supported in the 2800 series is here:
