LOSSARY
daughter card
Can be either OC-3c, OC-3c Single Mode Long Reach, OC-12c, Single
Mode or Multi-Mode or 155 Mbps-over-UTP5. These cards are attached
to the ATM Interface Carrier Module to make the Interface Module
complete.
Early Packet Discard
(EPD)
A procedure for discarding cells related to one user frame to minimize
the impact of congestion.
EFCI
Explicit Forward Congestion Indication. A 1-bit field in the PTI that
contains information about whether congestion at an intermediate
node has been experienced.
E-IISP
Extended Interim Interswitch Protocol. A signaling protocol that uses
network-to-network (NNI-based) signaling for communication.
Enterprise Engine
(EME)
The management engine for the CoreBuilder 9000 ATM Enterprise
Switch.
Enterprise Network
A network structure that is similar to a campus network.
Flash/Operational
Software LED
An LED that indicates in which software unit the error occurred.
Framer
An ATM Interface Module component that processes the SONET/SDH
frames, extracts the ATM cells from the incoming serial data, verifies
cell header validity and transfers cells to the ATM Layer Processor.
IISP (Interim
Interswitch Protocol)
A signaling protocol that uses user-to-network (UNI)-based signaling for
switch-to-switch communication.
Local Management
Application (LMA)
The graphic interface used to manage the Enterprise Switch locally.
loopback test
A test used to diagnose faulty cables as well as faults in the framer or
other components of a daughter card.
LAN
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.
loopback test
The loopback test is used to diagnose faulty cables as well as faults in
the framer or other components of a daughter card.
