1.4 Special Functions
AutoMDI/MDI-XFunction
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.
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 negotia- tion process for the speed and duplex configuration with the connected device automatically when each time a link is being established.
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 con- verter to report a fiber link fault even when a link failure occurred on transmitting fiber cable.
