High-Bit-Rate Digital Subscriber Line

   Abbreviated HDSL. A high-speed data transmission technology originally developed by Bellcore that delivers high bandwidth over existing twisted-pair copper telephone lines.
   HDSL is the most common Digital Subscriber Line (DSL) service and provides T1 data rates of 1.544Mbps over lines of up to 3.6 kilometers, or 12,000 feet, in length. HDSL is symmetric, providing the same data rate in each direction.
   The service is not intended for residential purposes, but is used in the telephone company's own private data networks, Internet servers, and interexchange connections.
