DSL

DSL (digital subscriber loop)

A technology that uses the original telephone company copper wires leading to and from customers' homes to deliver high-speed digital data services, approximately 300 times faster than normal analog transmissions. (Cingular)

Digital Subscriber Line, or DSL, is a family of technologies that provide digital data transmission over the wires of a local telephone network.

Typically, the download speed of DSL ranges from 128 kilobits per second (kbit/s) to 24,000 kbit/s depending on DSL technology and service level implemented. Upload speed is lower than download speed for Asymmetric Digital Subscriber Line (ADSL) and equal to download speed for Symmetric Digital Subscriber Line (SDSL).
