Line Build Out (LBO)
An optical attenuator that guarantees the proper signal level and shape at the receiver
input.
Link Pass Through (LPT)
The LPT mode is used to enable or improve network protection schemes on equipment
which is external to TransLAN® systems.
LNC
LiNe Controller (SLM)
LO
Low Order
LOF
Loss Of Frame
LOM
Loss Of Multiframe
Loop Timing
A timing mode in which the terminal derives its transmit timing from the received line
signal.
LOP
Loss Of Pointer
LOS
Loss Of Signal
Lower order Path Adaptation (LPA)
Function that adapts a PDH signal to a synchronous network by mapping the signal into
or de-mapping the signal out of a synchronous container.
Lower order Path Connection (LPC)
Function that provides for flexible assignment of lower order VCs in a higher order VC.
Lower order Path Termination (LPT)
Function that terminates a lower order path by generating and adding the appropriate VC
POH to the relevant container at the path source and removing the VC POH and reading
it at the path sink.
LPU
Line Port Unit
LRX
Line Receiver
LS
Low Speed
