"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Never heard of those.  I suspect they are vendor specific terms - which vendor are you looking at?

ADSL2 (ITU G.922.3 and G.922.4) are new ADSL standards that enchance existing adsl standards and utlize newer technologies.  ADSL2 can run up to 12MB/s (regular adsl is 8) and can give another 600 feet in distance from the local exchange.  2+ goes even further, bringing the total speed to 25MB/s and has about a 1.5 KM range from the local exchange.

They basically are able to enhance speed and distance by changing the algorithms that are used to interperet frequencies (how the data is transmitted over the phone line).  2+ also has the ability to multiplex lines, which means you can combine phone lines and get another 25MB/s each line you add.

Hope this helps...

ADSL2 & 2+ is the next phase of offerings from most ISP's.  This means, however, that who is offering it in your area is completely dependant on where you live.  Here's some articles discussing it:
