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.
