1.4 Special Functions
1.4.1 Auto MDI/MDI-X Function
This function allows the TP port to auto-detect the twisted-pair signals and
adapts itself to form a valid MDI to MDI-X connection with the remote
connected device automatically.
1.4.2 Auto-negotiation Function
When the TP port is set on Auto-negotiation mode (SW1:ON), it is featured
with auto-negotiation function and full capability. It performs a negotiation
process for the speed and duplex configuration with the connected device
automatically each time a link is being established.
1.4.3 Far End Fault Function
The FX port is facilitated with this function, which conforms to IEEE 802.3u
100BaseFX specifications. When the FX port detects a link failure on its
receiving circuitry, it will send out an FEFI (Far End Fault Indication) signal to
the remote connected device to indicate a remote fault is detected. It also is
capable of receiving a FEFI signal sent from the remote link partner. Upon
receiving an FEFI signal, it indicates a link failure occurred on the transmitting
path. This function allows the converter to report a fiber link fault even when
a link failure occurred on the transmitting fiber cable.
