Connecting Router to T1

[trumanzero]

I posted this in the Linksys forum, but I haven't been able to find a solution:
I have a fractional T1 connection coming into my home. The way that my network is setup right now has my servers and Linksy routers connected into an Intel switch and then from the switch to the T1. However, I am wanting to redesign the network (eliminate old/useless equipment and add some new stuff) by taking a BEFW11S4 wireless router straight into the T1 and then having the switch and everything else plug into the router. I have been trying all day to make this happen but no matter what I do I can't get anything to connect to the internet when I have the router straight into the T1. Everything works fine when everything goes through the switch to the T1, but not with the router. Is there anything that could be causing this problem? I have all of my business information stored on servers and I can't risk having them offline for very long, so I can't simply unplug everything and figure this out the hard way. Thanks.

Here's the link to the original topic for reference:

Your linksys router does not support a T1 connection.
It is a cable/DSL router that supports these, and only these, broadband types.

With the exception that somewhere you have a CSU/DSU unit, and you can sit behind this with the router.
