DSL (Digital Subscriber Line) is a technology that allows existing copper phone wire to transfer high speed data services. The advantage of using DSL is your computer is connected to a dedicated circuit allowing you to talk on your phone at the same time.

DSL does loose speed the further your connection is from the telephone company central office (CO). The condition of your existing copper phone wire also will affect quality and speed of your DSL service.

DSL service can improve speed up to 50 times faster than the traditional dial-up internet service. The increase in speed is possible because the DSL provider uses a dedicated secure telephone wire circuit that does not go through a CO analog switching equipment.
