[ale] [OT] dsl throughput

[Lightner, Jeff]

ILEC = Incumbent Local Exchange Carrier = the folks that own the phone lines in your area e.g. BellSouth (AT&T) for most of Atlanta Metro.

CLEC = Competitive Local Exchange Carrier = People that use those phone lines but sell service to you.  (Somewhat the way Atlanta Gas Light owns all the gas pipes but you can buy from SCANA, GNG or others.)   

The theory was it would be competitive like long distance was previously so you'd end up paying a lot less for home phone service.   The (alleged) practice is that ILECs put so many hurdles in front of CLECs and delayed their orders so long that it isn't economical for general phone service.  Most CLECs gave up on residential service and focused on business.

Funny that with the whirlwind of acronyns flying around that response,
the only one you chose to define was CO.

I have also seen it the other way around where the CLEC provides better bandwidth because they installed a DLSAM and the ILEC can't give you DSL at all because you're to far from the CO.

I haven't ordered DSL in many years so I don't know if it has gotten any better.
