Glossary
Access Line: A communications line (e.g. circuit) interconnecting a
frame-relay-compatible device (DTE) to a frame-relay switch (DCE).
See also
Trunk Line.
Access Rate (AR): The data rate of the user access channel. The
speed of the access channel determines how rapidly (maximum
rate) the end user can inject data into a frame relay network.
ANSI (American National Standards Institute): Devises and
proposes recommendations for international communications

AppleTalk: A comprehensive network system designed and
developed by Apple Computer, Inc. AppleTalk allows many different
types of computer systems, printers, and servers to communicate
on a variety of cabling schemes, including LocalTalk and Ethernet
cabling. In this manual, AppleTalk refers especially to the protocols
or rule sets that govern this communication.
AppleTalk address: A unique identifier for each device using
AppleTalk that allows information to be sent and received correctly.
An AppleTalk address always includes a network number wherever
two or more AppleTalk networks are connected together by routers.
AUI (Attachment Unit Interface): Usually refers to 15-pin D
connectors associated with Ethernet transceivers.
AURP (Apple Update-based Router Protocol): An enhanced
AppleTalk routing protocol. AURP provides improved support for
AppleTalk over wide area networks (WANs) and tunneling through
non-AppleTalk (IP) networks. AURP features include network number
remapping, clustering of remote network numbers, and hop count
reduction.
backbone: A network topology consisting of a single length of
cable with multiple network connection points.
