Pause Control Frame
When both ends of a full-duplex media coverter link are able to send and
receive Pause Control Frames AND the media converter four-position switch
is set to allow Pause Control Frame propagation (see page 3), then the Pause
Control Frame feature can improve network performance by allowing one
end of the link to signal the other to discontinue frame transmission for a set
period of time to relieve buffer congestion.

Link Pass-Through

When the media converter four-position switch is set to allow Link Pass-
Through (see page 4), then a fault on one side of the media coverter stops
signal and data transmission on the other side.

Far-End Fault

When the media converter four-position switch is set to enable Far-End Fault
(see page 4), then a fault on an incoming fiber link causes the media
converter to transmit a Far-End Fault signal on the outgoing fiber link.
