UUNET doesn't own dedicated single-circuit copper to people's houses.
Okay, now lets talk about a wide-scale xDSL implementation using a
reasonably well known POP architecture like UUNet's.
If xDSL can only run about 18kft end-to-end, to service a wide metro area
like Washington, D.C. one would either have to have a POP within every 6
mile radius (fed by conventional circuits) or backhaul the data (by
conventional circuit) to their POP.
Is this correct, if not, what am I missing?
