ADSL (Asymmetric Digital Subscriber Line) is a new transmission technology that provides up 6 Mbps downstream connectivity over the existing telephone lines. ADSL also offers the capability to receive data and use your telephone or fax machine at the same time. ADSL began as the phone company's way to compete with cable TV. Now, it is also a good candidate for high speed Internet access. ADSL will require special modems. Asymmetric Digital Subscriber Line The "A" stands for "Asymmetric", meaning that downstream and upstream speeds do not match. Upload speed of an ADSL line is about 1/10 the download speed. ADSL is one member of a continuum of last-mile transport systems called DSL, or Digital Subscriber Line. Each can carry from 1 to 6 Mbps over copper lines. Other variations of DSL are coming soon. In general, the faster the DSL access, the shorter the distance it can travel. DSL schemes will require signal repeaters between the central office and the home.
