GLOSSARY 135

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.

LES LAN Emulation Server provides address resolution for the LECs within 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.

level indicator The level indicator specifies the exact number of significant bits that are used for the peer group ID and can range from 0 to 104.

LM Local management of a network device via a connected terminal.

Local Management The LMA menu system is a set of command menus organized in a Application (LMA) hierarchic, top-down fashion. Each command menu contains a

menu system numbered list of menu items. Each menu item has a three-letter 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.

logical node An abstract representation of a peer group or a switching system as a single point.

logical uplink Any link between the lowest level hierarchy and the upper levels of hierarchy.

LOS Loss of Signal. A condition at the receiver or a maintenance signal transmitted in the PHY overhead indicating that the receiving equipment has lost the received signal. This is used to monitor the performance of the PHY layer.

LUNI LAN Emulation User to Network Interface. The standardized interface between a LE client and a LE server (LES, LECS and BUS).
