Link Fault Pass-Through (Lfpt) - IMC Networks IE-iMcV-Gigabit Operation Manual

FiberAlert (FA)
FiberAlert minimizes the
problems associated with the
loss of one strand of fiber. If
a strand is not available, the
IMC Networks device at the
receiver end notes the loss of
link. The
device will then stop transmitting data and the link signal until a signal or link pulse is
received. The result is that the link LED on BOTH sides of the fiber connection will
go out indicating a fault somewhere in the fiber loop. Using FiberAlert, a local site
administrator is notified of a fault and can quickly determine where a cable fault is
located.
Enable FiberAlert on one side of a media conversion only. Enabling it on both
sides would keep both transmitters off indefinitely.
Modules ship from the factory with troubleshooting features disabled.

Link Fault Pass-Through (LFPT)

Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and FX
LinkLoss from both the local and remote IE-iMcV-Gigabit Modules. LFPT is enabled
by turning on both FX and TX LinkLoss on both modules. This feature allows either
end of the conversion to detect a link fault occurring at the other end of the media
conversion chain.
