Digital subscriber line. A public network technology that delivers high bandwidth over
conventional copper wiring (such as telephone lines) at limited distances. There are
five types of DSL: SHDSL, HDSL, IDSL, SHDSL, and VDSL. All are provisioned
through modem pairs, with one modem located at a central office and the other at the
customer site. Because most DSL technologies do not use the whole bandwidth of the
twisted pair, there is room left for a voice channel. See also
