DSL:
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 128 Kbps 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 businesses.
