Does 4331 supports T1 WIC card

[jigarrg]

I have a very old router 1721 which is currently running frame relay on WIC card and i have to move to the new router ISR 4331. Does ISR supports T1 WIC card? And can i configure frame relay on top of it? 

ISR is running the latest IOS which i guess 16.6.4.

Hello,

if you are talking about the first generation WIC-1T, no, it is not compatible with the ISR4331. Yiou would need the NIM-1MFT-T1/E1.

Check the compatibility matrix below:

Thanks Georg. This cleared my doubt.
