A leased line modem is another name for a CSU/DSU.  These devices interpret line signals for your other network devices to use (like a router).  You'll need to order one E1/HDSL line if the sites are fairly close that is point-to-point and connect one of the RADs at each end.  Connect your routers to those units and work out the routing.  Alternatively, if they are farther apart, you will want to use a frame switch access or internet access (then set up a VPN) from a local provider (some companies are global, others only have this access in a small area).  This will mean that you need two lines ordered, one for each end.  The benefits are that if the two sites are with different carriers or geographically distant you won't spend as much for the initial circuit design and you can grow this network easily.  However, the maintenance charges on a PTP line are very low and if you have no plans to expand, may be the best choice.
