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 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. 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.
