DSL Glossary
100Base -T
A 100 Mbps LAN that maintains backward compatibility with 10Base-T networks
running at 10 Mbps.
10Base -T
A 10 Mbps Ethernet LAN which runs over twisted pair wiring.This network interface was
originally designed to run over ordinary twisted pair (phone wiring) but is predominantly
used with Category 3 or 5 cabling.
Access Line
The physical telecommunications circuit connecting an end user location with the
serving central office. Also called the local loop or "last mile."
Access Network
That portion of a public switched network that connects access nodes to individual
subscribers. The Access Network today is predominantly passive twisted pair copper
wiring.
Access Nodes
Points on the edge of the Access Network that concentrate individual access lines into a
smaller number of feeder lines. Access Nodes may also perform various forms of
protocol conversion. Typical Access Nodes are Digital Loop Carrier systems
concentrating individual voice lines to T1 lines, cellular antenna sites, PBXs, and Optical
Network Units (ONUs).
Access Rate
The transmission speed of the physical access circuit between the end user location
and the central office. This is generally measured in bits per second; also called Access
Speed.
Adapter Card
Circuit board or other hardware that provides the physical interface to a
communications network; an electronics board installed in a computer which provides
network communication capabilities to and from that computer; a card that connects the
Data Termination Equipment to the network. Also known as a Network Interface Card.
DSL (Digital Subscriber Line)
An ANSI standard developed by the Alliance for Telecommunications Industry Solutions
(ATIS) T1E1.4 committee and finalized in 1995 which defines a high-speed modem
capable of transmitting data over twisted pair copper wires. The I TU recommendation
G.992.1 for a physical layer implementation of an Asymmetric Digital Subscriber Loop
