ADSL Technology and Applications
ADSL is a broadband technology that provides high-speed data communications over existing copper telephone networks while simultaneously maintaining voice service. ADSL technology takes advantage of an existing infrastructure of over 750 million worldwide copper telephone lines to deliver data rates in excess of 6Mbps and as high as 12 Mbps. High data rates of modern ADSL systems make them attractive for such applications as internet access, video on demand, multiple voice channels. This presentation will review ADSL modulation technique known as discrete multi-tone, or DMT, current deployment of ADSL systems and there future.
