Maximum DSL speed is controlled by your distance from the central office. To get the maximum DSL speed you have to be less than 5000 feet from the central office. DSL was never an option for me since I am 26000 feet from my central office. There used to be a web site that could calculate your distance from your central office and then indicate what the maximum usable speed would be for that distance. I thought it was http://www.dslreports.com but they don't seem to offer that capability anymore. Years ago an ISP would not offer a speed that couldn't work but it appears today they will sell you whatever speed you are willing to pay for regardless of whether it can actually work. To get the best reliability for DSL it should not be distributed to every phone jack in your house. The incoming phone line should go through a DSL splitter to separate the DSL signal from the phone signal. The DSL signal should then be run directly to the phone jack that will be used for the DSL modem. Having a lot of unterminated wire going to other unused wall jacks can only serve to corrupt the DSL signal. The same is true if you have "naked" DSL except that you don't need the DSL splitter.
