From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
Digital Subscriber Line (DSL, or Digital Subscriber Loop, xDSL - see below) A family of {digital} {telecommunications} {protocols} designed to allow high speed data communication over the existing {copper} telephone lines between end-users and telephone companies. When two conventional {modems} are connected through the telephone system ({PSTN}), it treats the communication the same as voice conversations. This has the advantage that there is no investment required from the telephone company (telco) but the disadvantage is that the {bandwidth} available for the communication is the same as that available for voice conversations, usually 64 kb/s ({DS0}) at most. The {twisted-pair} copper cables into individual homes or offices can usually carry significantly more than 64 kb/s but the telco needs to handle the signal as digital rather than analog. There are many implementation of the basic scheme, differing in the communication {protocol} used and providing varying {service levels}. The throughput of the communication can be anything from about 128 kb/s to over 8 Mb/s, the communication can be either symmetric or asymmetric (i.e. the available bandwidth may or may not be the same {upstream} and {downstream}). Equipment prices and service fees also vary considerably. The first technology based on DSL was {ISDN}, although ISDN is not often recognised as such nowadays. Since then a large number of other protocols have been developed, collectively referred to as xDSL, including {HDSL}, {SDSL}, {ADSL}, and {VDSL}. As yet none of these have reached very wide deployment but wider deployment is expected for 1998-1999. {(http://www.cyberventure.com/~cedpa/databus-issues/v38n1/xdsl.html)}. {2Wire DSL provider lookup (http://www.2Wire.com/)}.
