I am upgrading the hardware for a T1 circuit we have. I currently have a 2811 with a WIC 1DSU T1 module. This is working fine.
I am going to replace the 2811 with a 3845. I tried to put in the WIC 1DSU T1 module but the router didnt see the card. After digging around I found out that the 3845 does not support that card.
So what is the equivalent of the WIC 1DSU T1 module for the 3845?
