IEEE standard for Ethernet local area networks.
IEEE standard for bridging.
Interface card communications is the communications protocol between
the switch card and the installed interface cards.
Transmission of auxiliary information, e.g., management messages over
the media also used by the system users.
Up to four interface cards can be placed in the CoreBuilder 7000. Each
interface card contains four ATM ports for connection to network
devices.
Clock that comes from the local clock on the PB.
Internet Protocol. The protocol governing packet forwarding within the
Transmission Control Protocol/Internet Protocol (TCP/IP) suite of
standards developed and used on the Internet.
Internet Protocol address. A unique identifier for a machine attached to
a network made up of two or more interconnected local area or wide
area networks.
L
Local Area Network. A data communications network spanning a
limited geographical area, such as a single building or campus. It
provides communication between computers and peripherals. LANs are
distinguished by their small geographical size, high data rate, and low
error rate.
LAN Emulation. The set of services, functional groups and protocols
which provide for the emulation of LANs utilizing ATM as a backbone
to allow connectivity among LAN and ATM attached end stations.
LAN Emulation. See LANE.
LAN Emulation Client. The ATM Forum defined specifications in support
of LAN-to-LAN connectivity called LAN Emulation. LEC defines that set
