2GLOSSARY
ATM LAN Topology that consists of ATM switches and
computer interfaces that provide high data rate
connectivity for voice, video, and data (IP, SNA, and
multimedia).
BUS Broadcast and Unknown Server. A server within
LAN emulation (for ATM networks) that has the ability
to receive broadcast requests from all other stations
on the network, and forward them to a multicast
switch. The switch, in turn, broadcasts the requests
to all other stations on the network.
Call control
A process that uses the signaling procedures to
establish connections. The connection is actually
much like a telephone call, and the processes are
sometimes referred to as “call setup” and “call
control” procedures.
Call setup Method of opening up circuits to provide the
necessary bandwidth in local or remote networks.
CBR Constant Bit Rate. The transmission of bits at a
fixed rate over a network.
CCITT International Telephone and Telegraph Consultative
Committee. The international standards body for
telecommunications.
Cell The basic data unit used to transmit information
through an ATM network. The cell is 53 bytes in
length and supports high-speed packet switching
techniques.
