When a 10/100BaseT port is lost, the unit sends a fault signal (RAI) to the
VDSL line. If the LFPT function is enabled at the Far End VDSL port
receiving this fault indication, the far end unit will drop the link on the
10/100BaseT port and BLINK the LFPT LED. This function must be enabled
at both ends of the VDSL line for this to function in both directions. The
LFPT function is only active in one direction at a time and is indicated by the
flashing LED. As such, clearing the far end fault may uncover a fault at the
local end.
