Looks like BellSouth big off more than they could chew... From the DSL
reports newsletter:
> BellSouth Cut "Fiber" Speed More Than 80% Originally shipped 10/10,
> cut to 1.5/384K BellSouth has installed perhaps a million lines of
> "fiber to the curb," but hasn't connected the users at speed. I've
> now discovered, talking to a former Reltec engineer, that the
> original systems were designed with 10 mbps upstream and down to each
> home (ordinary ethernet). However BellSouth chose to downgrade the
> speed to a tenth of what the system was designed for. My assumption
> is they didn't want other customers complaining about their
> relatively slow speeds.
