Digital Subscriber Line or Loop
A family of technologies that provide digital data transmission over the wires of a local telephone network.
DSL originally stood for digital subscriber loop, although in recent years, many have adopted digital subscriber line as a more marketing-friendly term for the most popular version of DSL, ADSL.
Typically, the download speed of consumer DSL services ranges from 256 kilobits per second (kbit/s) to 24,000kbit/s, depending on DSL technology, line conditions and service level implemented.
Typically, upload speed is lower than download speed for Asymmetric Digital Subscriber
Line ADSL and equal to download speed for Symmetric Digital Subscriber Line SDSL.
