I'm sorry Ford, but the discussion is regarding broadband access, and you
cannot service 1000 broadband customers using 60% of a 1.54Mb circuit. Many
years ago you could service 1000 small dial-up customers with a small feed
like a T1. Not today. A single heavy-use broadband customer can easily use
60% of a T1 24/7. 1000 broadband customers on a T1? Not a chance. You are
also forgetting transport costs.

One of the issues that BPL proponents argue is that BPL can provide
broadband access to rural communities that have been passed over by cable
and DSL. If a community is truly that rural (and there are many such areas)
then the transport cost alone for the Internet feed will be much more than
the cost of the Internet feed. (There are two separate costs - transport and
bandwidth.) As a result, the net cost is many times more expensive than the
equivalent cost in a metro area. For example, the cost of bandwidth in
Manhattan is very cheap compared to the same very expensive bandwidth in
Bone, Idaho. Today it is still very expensive to haul big bandwidth into
small rural areas. Don't underestimate that cost.
