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 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 when 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 100BASE-FX
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 to receive 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 transmitting fiber cable.
