DSL is very much distance sensitive. The further away from the provider's central office (CO) you're located, the slower your speeds will be. That's why they say "up to...". 3 Mpbs/512 Kbps is probably an ideal case scenario when you're literally right next to the CO.
No. ADSL is capable of 7Mbit down/1Mbit up even when you are a decent distance from the CO. This of course varies based on line conditions as well. You can have a long clean line that gives a much better sync than a short (close to the CO or remote) dirty line. In my experience you can get ~6Mbit down/1Mbit up on ADSL within about a 2Km (line distance) range.
ADSL2+ is capable of 24Mbit down/1Mbit up when within relatively short proximity of the CO. I'm 1.5Km line distance from the CO and am currently sync'd at 18.6Mbit/1Mbit.
ADSL providers use "remotes" to cover distances that are outside the range of the CO. Most ISP's have the ability to determine whether you sync to the CO or a Remote. In Ontario, in many cases you are at the mercy of Bell Canada, even when with a 3rd party ISP as to whether you are on a remote or at the CO, and whether the remote you are synching to is the closest to your location physically or not. If the Bell remote close to your location is close to capacity, and you are not being served by Bell directly, they may put you on a remote that is much further away but has fewer subscribers. This is to save ports for those who subscribe to Bell (Sympatico) directly. Not very fair.... But that's what we deal with up here.
