1.4.1 Digital Subscriber Line (DSL)

DSL is 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 consumer-ready DSL. They are sometimes referred to as last-mile technologies because they are used only for connections form a telephone switching stations.

DSL is similar to ISDN in as much as both operate over existing copper telephone lines and both require the short runs to a central telephone office(usually less than 20,00 feet). However, DSL offers much higher speeds-up to 32 Mbps for upstream traffic (Client to server), and form 32 Kbps to over 1Mbps for downstream traffic (server to client)
