Link Fault Pass Through (Lfpt); Far End Fault (Fef); Autocross Feature For Twisted Pair Connection - Advantech B+B SmartWorx iMcV-Giga-MediaLinX TX/SFP User Manual

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-Giga-MediaLinX
TX/SFP. LFPT is disabled 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.

FAR END FAULT (FEF)

FEF is permanently enabled for 100Mbps. When enabled, and a fault occurs
on the fiber line, affecting data in one direction, an FEF signal will be sent in
the opposite direction, indicating the fault. When enabling LFPT, FXLL will act
on this signal propagating the loss of link to the copper port when FXLL is
enabled. The FEF function can trigger the FA function and may keep both
transmitters off indefinitely. For more information on LinkLoss, visit the B+B
SmartWorx website or contact the B+B SmartWork Technical Support.
AUTOCROSS FEATURE FOR TW ISTED PAIR CONNECTION
All twisted pair ports on the iMcV-Giga-MediaLinX TX/SFP include AutoCross,
a feature that automatically selects between a crossover workstation and a
straight-through connection depending on the connected device.
