Glossary D-2
DSL
Digital Subscriber Line — A technology that transforms ordinary telephone lines
into high-speed digital lines for fast Internet access. This technology uses a digital
coding technique to get large capacity out of existing phone lines without
interfering with regular services — one can use the phone and surf the Internet at
the same time. In this way, DSL provides simultaneous Internet and voice/fax
capabilities over a single telephone line without any interference.
Ethernet
A local-area network (LAN) protocol that supports data transfer rates of 10 Mbps.
It is one of the most widely implemented LAN standards that operates using the
twisted pair or coaxial cable. A version of Ethernet, called 100 Base-T (or fast
Ethernet), supports data transfer rates of 100 Mbps.
G.dmt
An industry standard known as G.992.1, which refers to ADSL technology that
uses DMT modulation and that does not require a splitter box to be installed at the
user’s premises. This technology supports downstream data rates of up to 8
megabits per second and upstream data rates of up to 960 kilobits per second.
G.Lite
A “splitterless” ADSL technology that uses CAP or DMT modulation, and supports
downstream data rates of up to 1.5 megabits per second and upstream data rates
of up to 384 kilobits per second.
Hub
A device used for connecting nodes in a star topology, that is, all the nodes are
connected to a central hub. A passive hub simply organizes the wiring, while an
active hub also regenerates and retransmits signals.
Internet
The world’s largest computer network, which links computers and networks that
communicate via the standard TCP/IP protocol.
