Glossary
G.lite
A kind of asymmetric DSL technology, based on DMT modulation, that offers up to
1.5 megabits per second downstream bandwidth, 384 Kilobits per second upstream,
does not usually require a splitter and is easier to install than other types of DSL.
"G.lite" is a nickname for the standard officially known as G.992.2.
IP address
An identifier for a computer or device on a TCP/IP network. Networks using the
TCP/IP protocol route messages based on the IP address of the destination. The format
of an IP address is a 32-bit numeric address written as four numbers separated by
periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP
address.
ISP
Short for Internet Service Provider, a company that provides access to the Internet.
LAN
Short for Local Area Network, a computer network that spans a relatively small area.
Most LANs are confined to a single building or group of buildings and connect

Short for Point-to-Point Protocol, a method of connecting a computer to the
Internet. PPP sends the computer's TCP/IP packets to a server that puts them onto the
Internet.
T1.413
The American National Standards Institute (ANSI) standard for asymmetric digital
subscriber line using discrete multitone modulation, which the G.dmt standard is
based on.)
TCP/IP
Short for Transmission Control Protocol / Internet Protocol, the suite of
communication protocols used to connect hosts on the Internet.
Upstream
The direction of an upstream signal is from the user's computer to the ISP/service
