We call this technology a Frame Relay cloud.

You have *one* connection into the central offices at T1 or T3
speed, and your customers endpoint on your cloud.

You pay for *one* line and amortize the cost over all your customers,
your customers pay for *one* line.

You need *one* interface for all of them.

How about one DS3 into a cloud...  The T1 circuits never see your building.

If your NSP goes into the same cloud, your building necer sees wires
unless you want your own connection.  8-).
