The circuits are being provided by a CLEC.  The carrier has fiber in our 
facility, so they're able to drop a DS-3 to us in about a week from 
now.  The idea is to eliminate technicians from being dispatched at our 
end of the facility whenever another DS1 is ordered, and to minimize the 
amount of equipment sitting around to service each of those DS1 
customers.  As far as I know, the DSU is CPE.  The carrier will be 
bringing us two coax cables and nothing else.

We'll be getting a channelized DS3 which will consist of up to 28 DS1 
circuits.  Initially, we'll have 10 DS1 circuits, and we expect to fill 
the others in the next six months.
