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 McBasic-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. FiberAlert can also be enabled at the main
site.
If a cable fault occurs on the remote devices’ twisted pair port, then TX LinkLoss
detects the fault and disable the OPTICS port.
If a cable fault occurs on the remote devices fiber optics’ port, then FX LinkLoss
detects the fiber loss and disables the Twisted Pair port.
The link fault is passed through the media conversion and is observed at each
end. It acts just like it would if the devices were directly connected.
