DSL on long copper loops

Just for the record, I have Bellsouth DSL at my house. I'm over 19.5Kft of circuit from their CO. (Probably more like 20K)

I get consistently at *least* 520kbps down, 256kbps up.
The highest I get is 716kbps sync down, 256kbps up (upload speed limit of provider).

If the phone company tells you that DSL doesnt work past 15Kft then they're full of shit.

If you work them hard enough and get to know some of the people in the CO/sales office you can usually get a connection if you're less than 22Kft. 22kft is about the maximum distance of ADSL (without a repeater).


some info

@banetworkdata.com

The equipment that is used to bring you DSL gets better all of the time as does the line quality. What was true in DSL distance requirements in the past is not true today.

Equipment performance/quality improvements notwithstanding, the reason they operate this way is all a numbers game. They've found that beyond distance X, the number of signal quality-related support calls (and therefore the cost of serving these circuits) is beyond their profit margin tolerance. Ergo, while loops out to 22k might work, in their Infinite Wisdom (TM) they've decided to cut their losses and declare 15k to be their limit. 12k used to be the limit here, but they're now willing to service up to 15k. Go figure. Maybe they're (Verizon) getting better at what they're doing.
