DSL can do that. There are some million posts on DSL so I don't want to add much but keep it short.

For DSL I don't want to have a large number of phone outlets in the home. In fact the best DSL run is what they call a HOME RUN. (DSL Techs know what this is)

Remember all about how to wire DSL is out there so again I keep it short. I unplug ALL devices from the phone lines save the lone modem. I try it on another jack and be sure the line is the one that came with the modem. A filter is not used on the modem connection (whoops, repeating the web there.)
