Fast Ethernet Converter Features: 100Base-TX to 100Base-FX
| Auto-Negotiation (802.3u) |
The media converter supports auto negotiation
on the fast ethernet 100Base-TX interface. |
| Auto-MDIX |
Auto-MDIX (automatic medium-dependant
interface crossover) detects the signaling on the 100Base-TX interface
to determine the type of cable connected (straight-through or crossover)
and automatically configures the connection when enabled. With
Auto-MDIX enabled, either a straight-through or crossover type cable can
be used to connect the media converter to the device on the other end
of the cable. |
| Link Pass-Through |
With Link Pass-Through the state of
the 100Base-TX receiver is passed to the 100Base-FX transmitter to make
the media converter appear transparent to the end devices that are
connected. In addition if Far-End Fault is enabled the media converter
can turn off the 100Base-TX transmitter when a FAR-End Fault is
received.
Using Link Pass-Through with Far-End Fault minimizes
data loss when a fault occurs. Should a fault occur, the end devices
have the indication of a failure available to them making trouble
shooting easier. |
| Far-End Fault (FEF) |
The media converter implements the
802.3 standard for Far-End Fault for the indication and detection of
remote fault conditions on the 100Base-FX fiber connection. With Far-End
Fault enabled the media converter transmits the Far-End Fault
Indication over the 100Base-FX fiber connection whenever a receive
failure is detected on the 100Base-FX fiber connection. The media
converter continuously monitors the100Base-FX fiber connection for a
valid signal.
The action the media converter takes on receiving
a Far-End Fault Indication is dependent on the Link Pass Through switch
setting. |
| Pause (IEEE 802.3xy) |
Pause signaling is an IEEE feature
that temporarily suspends data transmission between two devices in the
event that one of the devices becomes overwhelmed. The fast ethernet
media converter supports pause negotiation on the 100Base-TX copper
connection. |
| VLAN |
The media converter is transparent to VLAN
tagged packets. |
