Understanding DSL and How it Works

DSL (Digital Subscriber Line) provides a much faster connection than a regular dial-up connection. DSL uses the existing 2-wire copper phone wiring and you usually don't need another phone line. This gives you an "always-on" Internet access, yet doesn't tie up your phone line.

DSL speeds are available in a range from 144 Kbps to 1.5Mbps. This is 2.5x to 25x times faster than a standard 56Kbps dial-up modem. DSL is useful for sending bandwidth-intensive applications like streaming audio/video, video conferencing, telephone calling, application programs, online games and other high-bandwidth services.

Today, DSL is used in homes as well as small and medium-size businesses. DSL takes existing voice cables that connect the customer's location to the phone company's central office and turns them into a high-speed digital link.
