Digital Subscriber Line


Digital Subscriber Line
   Abbreviated DSL. A high-speed data transmission technology originally developed by Bellcore that delivers high bandwidth over existing twisted-pair copper telephone lines.
   There are several DSL services, providing data rates from 16Kbps to 52Mbps. The services can be symmetrical, with the same data rate in both upstream and down stream directions, or asymmetrical, with the downstream capacity greater than the upstream capacity. Asymmetric services are particularly suitable for Internet users, because more information is downloaded than is uploaded.
   As DSL data rates increase, the distance over which the service is provided decreases; certain users who are located too far from the telephone company's central office may not be able to obtain the higher speeds or, in some cases, may not be able to receive the service at all.
