Glossary

G.lite

A kind of asymmetric DSL technology, based on DMT modulation, that offers up to

1.5megabits 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 workstations and personal computers. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN).

There are many different types of LANs, where Ethernet being the most common for PCs.

LED

Short for Light Emitting Diode, a type of control lamp on devices that indicates the status of a device.

Password

A secret series of characters that enables a user to access a file, computer, or program. On multiuser systems, each user must enter his or her password before the computer will respond to commands.

POTS

Short for Plain Old Telephone Service, which refers to the standard telephone service that most homes use. The POTS network is also called the Public Switched Telephone Network (PSTN).

PPP

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 provider (uploading).
