LOSSARY
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
Management Engine
(EME)
The management engine for the CoreBuilder 9000 ATM Enterprise
Switch.
Enterprise Network
A nework structure that is similar to a campus network.
Flash/Operational
Status 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.
Gateway Interface
Type (GWY)
A static routing protocol between an edge device (user) and a switch
(network) (UNI). Gateway is also refered to as IISP.
IISP (Interim
Inrterswitch Protocol)
A signaling protocol that uses user-to-network (UNI or GWY)-based
signaling for switch-to-switch communication.
Local Management
console (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.
Module Status LED An LED that indicates the system state of the ATM Interface Module.
multiplexing A function within a layer that interleaves the information from multiple
connections into one connection.
Network to Network
Interface (NNI)
ITU-T-specified standard interface between nodes, typically ATM
switches within the same network. This network uses e-IISP as its
signalig protocol.
