Digital subscriber line, abbreviated as DSL, is a family of technologies that allows for digital data transmission over the wires of a local telephone network. DSL can be used at the same time and on the same telephone line as normal telephone calls since DSL operates at high-frequency bands while the telephone call uses low frequencies. The most common form of DSL technology is ADSL, or Asymmetric digital subscriber line, where the bandwith used in either direction is different.
