Re: The numbers just don't add up.
Heck, I'd be happy if I just get DSL. Despite being in the city, I am "too far" from the CO. Does anyone know if this new "ADSL2+" has the same distance limits?

The higher speed you want the less distance you can go. They are coming out with more efficient data compression/modulation but you can only do so much and you still have hard signal to noise limits you can't go below.
For ADSL you need to be within about 3miles of a CO or fiber/T1 termination. ADSL2+ is about twice the speed of ADSL so you need to be between 1 and 2 miles away. VDSL is currently about 16times faster than ADSL downloading with a theoretical limit of about 32 times faster. For 16times faster you need to be less than 1/2 mile from a CO or fiber/T1 termination. Practically speaking, they probably don't want to be beyond 1000feet. These are wire distances not as the bird flies distances. You may only be 1/2 mile from the CO but the wire distance could be 1 mile or more. |

| Well, I'm just over 5km from the CO. Now that's based on the most recent measurement, which was almost 2 years ago. Having had first-hand experience with these matters, it's entirely possible that I'm a different distance today. Regardless, it still looks like I'll be "too far" even for ADSL2+.  |
