Well I found this on there site.

Or, for just $10 more per month, you can enjoy our top-speed connection, 6 Mbps/768 Kbps, and enjoy download speeds up to 70 times faster than 56K dial-up and five times as fast as 768K DSL. It's so unbelievably fast, you'll wonder how you ever surfed the Web without it.

I will have too look into this.
