T1 Point To Point Hardware Setup

Ok, i’m just getting into T1 connections and networking. This question is going to be very basic. I have 2 locations, building A has the smart jacks for both the incoming T1 and the Point to Point connection. Building B has a jack for the Point to Point connection.

I have a Netvanta router on Building A for the main internet, what do i need as far as hardware to get the point to points connected from Building A to Building B?

Any push in the right direction would be great.
Thanks
