Glossary
2B+D ‹ See BRI (Basic Rate Interface) .
23B+D ‹ See PRI (Primary Rate Interface) .
30B+D ‹ See PRI (Primary Rate Interface) .
802.2 IEEE ‹ Standards that govern the LLC within the Data Link
layer of the OSI model. LLC frames carry user information between
the nodes on a network and define the transmission of a frame between
two stations. These standards are common across the various lower
level standards within the Data Link and the Physical layers.
802.3 IEEE ‹ Standards that govern the use of the CSMA/CD (Carrier
Sense Multiple Access/Collision Detection) network access method
used by Ethernet networks.
802.5 IEEE ‹ Standards that govern the use of the token ring indicator
and frame priority.
Adapter ‹ A device, usually a user interface card, that physically con-
nects an end station to the network medium (for example, twisted pair,
coaxial, fiber).
Advanced program-to-program communication ‹ See APPC.
AIS (Alarm Indication Signal) ‹ PRI alarm, also known as Keep
Alive or Blue signal.
AMI (Alternate Mark Inversion) ‹ A method of digitally encoding
data as electrical signals on a link.
ANSI (American National Standards Institute) ‹ An organization
which coordinates, develops, and publishes standards used in the
United States.
APPC ‹ Advanced Program-to-Program Communications.The gen-
eral facility characterizing the LU 6.2 architecture and its various
implementations in products. 2. Sometimes used to refer to the LU 6.2
architecture and its product implementations as a whole, or to an LU
6.2 product feature in particular, such as an APPC application pro-
gramming interface.
