DSL (Digital Subscriber Line) is a technology for bringing
high-bandwidth information to homes and small businesses over ordinary copper telephone
lines. xDSL refers to different variations of DSL, such as ADSL, HDSL, and RADSL.
Assuming your home or small business is close enough to a telephone company central office
that offers DSL service, you may be able to receive data at rates up to 6.1 megabits
(millions of bits) per second (of a theoretical 8.448 megabits per second), enabling
continuous transmission of motion video, audio, and even 3-D effects. More typically,
individual connections will provide from 1.544 Mbps to 512 Kbps downstream and about 128Kbps
upstream. A DSL line can carry both data and voice signals and the data part of the line
is continuously connected. DSL installations began in 1998 and will continue at a greatly
increased pace through the next decade in a number of communities in the U.S. and elsewhere.
Compaq, Intel, and Microsoft working with telephone companies have developed a standard and
easier-to-install form of ADSL called G.lite that is accelerating deployment. DSL is expected
to replace ISDN in many areas and to compete with the cable modem in bringing multimedia and
3-D to homes and small business
