What does DSL mean?
DSL stands for Digital Subscriber Line. It is a term used to describe a range of high-speed (broadband) communications services offered over the Public Switched Telephone Network (PSTN). The PSTN uses a pair of copper wires to connect your telephone service to the national telephony network. DSL technology enables high-speed communications over these same copper lines by making use of the frequencies not used by voice communications - the frequency spectrum (range) between 0kHz and 4kHz is used for your telephone service and 20kHz to 2.2MHz for your DSL (ADSL or ADSL2) service.
