IOS issues with 3725 and NM-1ce1t1_PRI

[admin_2]

3725 router with NM-1ce1t1_PRI module installed:

Which IOS do I need to get this to function? The IOS installed doesn't recognize the 'controller' command when given at the config# prompt. I've tried a few different IOS versions, but all have the same symptoms. Am I missing something?

Found the solution. I had neglected to set "card type t1" from the config# menu. Solved the problem.
