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.
1.
A cable fault occurs on the remote twisted pair.
2.
TX LinkLoss detects the fault and disables the OPTICS (or UPLINK) port.
3.
FX LinkLoss detects the fiber loss and disables the DATA 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.
