Hi, I have a quick question: Is a controller t1 card compatible with a 1841 router? We've been trying to replace our old hardware, including controller cards, but in one instance, we found out we still need this setup. When we replace the old Cisco 2610 router, can we just use the same controller t1 card in our new Cisco 1841 router? Thanks!
Well, the data sheet says it is supported, but you might want to have a backup plan in case they do not work. The 2800 data sheet says it supports vwic-2mft-t1, but I had 2 sets of those wics, ones pulled from 2600s and ones ordered with the 2800s. The ones from the 2600s appeared identical, but they had older hardware revisions and would not work in 2800s.
