LOSSARY
of functions implemented in a LAN edge device to interface with an
ATM network in support of LAN Emulation.
LEC ID LAN Emulation Client Identifier: This identifier, contained in the LAN
Emulation header, indicates the ID of the ATM host or ATM-LAN bridge.
It is unique for every ATM Client.
LECS LAN Emulation Configuration Server. This is the set of functions that
provides an edge device with information regarding the location of the
other LAN Emulation Services, that is LES and BUS.
LAN Emulation Server provides address resolution for the LECs within
LES
an Emulated LAN. An LES receives an IP address from its own tables or
by querying the other LECs, and returns it to the requesting LEC.
The level indicator specifies the exact number of significant bits that are
level indicator
used for the peer group ID and can range from 0 to 104.
Local management of a network device via a connected terminal.
LM
The LMA menu system is a set of command menus organized in a
Local Management
hierarchic, top-down fashion. Each command menu contains a
Application (LMA)
numbered list of menu items. Each menu item has a three-letter
menu system
mnemonic identifier and a short description of the item. There are two
kinds of menu items: commands that display another, lower-level,
command menu ( submenu ) and commands that perform a specific
administrative task.
logical group nodes A logical group node that represents a lower level peer group as a
single point for purposes of operating at one level of the PNNI routing
hierarchy.
logical link An abstract representation of the connectivity between two logical
nodes. This includes individual physical links, individual virtual path
connections, and parallel physical links and/or virtual path connections.
An abstract representation of a peer group or a switching system as a
logical node
single point.
Any link between the lowest level hierarchy and the upper levels of
logical uplink
hierarchy.
LOS Loss of Signal. A condition at the receiver or a maintenance signal
transmitted in the PHY overhead indicating that the receiving
