Re: DSL

DSL, ADSL, ADSL2+, and most DSL technologies have one enourmous drawback. To get more upload then about 1 Mbps, you pretty much need to live right next to the CO.

VDSL can give you up to about 5 Mbps upstream provided you are actually within 800ft of the CO or something like that. U-Verse from AT&T has 1.5 Mbps upload, BUT you have to be close to a DSLAM for that.

Telco's need to switch to fiberoptics to get the powerusers. My cable company offers 15/2 connections (for businesses, I have 10/1 but i think they will upgrade everyone). NO telco is going to give me that (I am 11000 ft from the CO) unless they run fiber into my home.
Umm, did someone forget about Annex M by any chance ? Annex M gives ADSL2+ up to 3Mbps upload speed yet these guys aren't even offering it.. makes you wonder..

While it is rather easy to increase upload performance for DSL one does so at the expense of download. The total capacity of DSL is limited by attenuation and noise sources.
