About DSL Connections

Digital Subscriber Line (DSL) is a family of all-digital, high-speed lines that use your normal phone wires with special modems on either end. Most DSL lines are actually ADSL (Asymmetric Digital Subscriber Line). ADSL is optimized for the way many people use the Internet: more downloads than uploads. The line is asymmetric, because it has more capacity for data received by your computer (such as graphics, video, audio, and software upgrades) than for data that you send (such as e-mail and browser commands).
