layer
In the OSI reference model, a collection of related network processing
functions that comprise one level of a hierarchy of functions.
LC
1 See link controller (LC) (page 72).
2 See logical channel (LC) (page 76).
LCN
See logical channel number.
LCo
See logical connection (LCo) (page 76).
LD-CELP
See Low-delay code excited linear prediction (LD-CELP) (page 77).
LDS
See link delay synchronization (LDS) (page 73).
leaf
Is sometimes used interchangeably with party. However, a leaf more
accurately denotes any single destination point of a point-to-multipoint call.
LEN
See low-entry networking (LEN) node (page 77).
level
In ATM networking, a level is the position in the PNNI hierarchy at which a
particular node or peer group exists. A level that has a smaller numerical value
implies greater topology aggregation. Conversely, a level that has a larger
numerical value implies less topology aggregation. Smaller numerical values
indicate high levels while larger numerical values indicate lower levels.
LG
See link group (LG) (page 73).
LGN
See logical group node (LGN) (page 76).
LGN Horizontal Link Hello protocol
The LGN (logical group node) Horizontal Link Hello protocol is a protocol run
over an SVCC RCC channel to discover and monitor logical links between
neighboring logical group nodes.
