GLOSSARY
LECS (LAN Emulation Configuration Server) - the LECS is responsible for the initial configuration of LECs. It provides information about available ELANs that a LEC may join, together with the addresses of the LES and BUS associated with each ELAN.
leq - a FORE program that provides information about an ELAN. This infor- mation is obtained from the LES, and includes MAC addresses registered on the ELAN together with their corresponding ATM addresses.
LES (LAN Emulation Server) - the LES implements the control coordination function for an ELAN. The LES provides the service of registering and resolv- ing MAC addresses to ATM addresses.
LLC (Logical Link Control) - a protocol developed by the IEEE 802 commit- tee for
LOF (Loss Of Frame) - a type of transmission error that may occur in wide- area carrier lines.
looptest - a program that tests the interface for basic cell reception and trans- mission functionality. It is usually used for diagnostic purposes to determine if an interface is functioning properly.
LOP (Loss Of Pointer) - a type of transmission error that may occur in wide- area carrier lines.
LOS (Loss Of Signal) - a type of transmission error that may occur in wide- area carrier lines.
MAC (Media Access Control) - a
Metasignalling - an ATM Layer Management (LM) process that manages dif- ferent types of signalling and possibly semipermanent virtual channels (VCs), including the assignment, removal, and checking of VCs.
Metasignalling VCs - the standardized VCs that convey metasignalling information across a
MIB (Management Information Base) - the set of parameters an SNMP man- agement station can query or set in the SNMP agent of a networked device (e.g., router).
MIC (Media Interface Connector) - the optical fiber connector that joins the fiber to the FDDI controller.
