"Q: What's the difference between ADSL and SDSL (#1139)
A: ADSL is a DSL line that is mostly for low use. It has download speeds many times faster than its upload speeds. This is usually for simple tasks such as downloading and viewing webpages.

SDSL has upload speeds almost the same as its download speeds. This makes it optimal for gaming and servers of any type. Because the upload speed is high it is more expensive than ADSL.

For most uses ADSL is the best choice."

just to add:

ADSL = asymmetric blah blah blah: download and upload speed not symmetric (not equal).
SDSL = symmetric blah blah blah: download and upload speed symmetric (equal).

Yep, real simple. Most average users download more than they upload, so why give them all that unused bandwidth? = ADSL

Businesses though, tend to send a lot of data too, so they really need it, lets give it to them, and charge them a lot = SDSL

Expect to get aDSL unless you want to pay a bundle more then $40-50 a month for it (if its no cost difference, take it and run)

its explained on howstuuffworks.com

basically the telephone line can carry certain frequencies, they are broken into about fifty blocks, aboout five get used for voice, and the rest are for DSL. in ADSL 3/4 are for downloading and 1/4 for uploading hence 125kbps/500kbps, and for sdsl they are split equally, so 300kbps/300kbps or whatever the exact rates are. Thats what the filter is for, it just has a frequency cut off so only the voice noise gets through.

You also need to be aware of what type of encoding the xDSL line uses ie; G.dmt, g.Lite etc...... as most will not operate with each other.
