Order the T1 (ESF, B8ZS).  As you order the circuit specify where you
want it to end up ("server room, 2nd floor") and that you want an extended
demarc (will cost extra).

AT install time, make sure someone is around to cajole the installer
into getting the NIU as close as you can to where your router will be.
The installer should test from the extended demarc (make sure they do).

I have had LEC's tell me that the extended DMARC is only warranted for 3
months after install. Any work to the extended DMARC will cost you after
that if the trouble is within the extended DMARC. I have had telco techs on
site flat out refuse to repair an extended DMARC or tell you that it has to
be scheduled and will take a week to schedule. Occasionally a friendly tech
will just fix it for you without charge so, YMMV.

Get a standard built-in T1 dsu like as been mentioned in previous posts.
Plug it into the extended demarc with an ethernet patch cable.

Now, even though I say to not worry, it is important to remember the
#1 lesson when dealing with telephone companies.  I figure it is the
same all over the world, but just in case it isn't, I'll repeat it here:

  The telco is not your friend.

Indeed. But be nice to the techs, save the anger for their management.
