Whats the difference between SDSL and ADSL?
3a. ADSL has “Asymmetric” line speeds, that is, the speed from the internet to you, and you to the internet, are different. This is the most common setup for broadband, as people don’t require these speeds be the same for general internet access. 3b. SDSL is “symmetric”, that is, the speeds between you and the internet are the same in both directions. Currently, for residential and basic business applications, the only SDSL available is 512k/512k. Higher speeds are available on special request from some providers, but costs considerably more than regular ADSL. It’s only usually used for larger businesses that need dedicated high speed internet access.
