| Auto-Negotiation (802.3u) |
The media converter supports auto
negotiation. The 1000Base-X fiber interface negotiates according to
802.3 clause 37. The 10/100/1000Base-T negotiates according to 802.3
clause 28 and 40. The 1000Base-X will link up with its partner after the
highest common denominator (HCD) is reached and the copper has linked
up with its partner. The 1000Base-X will continue to cycle through
negotiation transmitting a remote fault of offline (provided this is
enabled through the switch setting) until the copper is linked up and
the HCDs match.
The media converter supports auto-negotiation of full duplex, half
duplex, remote fault, full duplex pause, asymmetric pause and Auto
MDI-X. |
| Auto-MDIX |
Auto-MDIX (automatic medium-dependant
interface crossover) detects the signaling on the copper ethernet
interface to determine the type of cable connected (straight-through or
crossover) and automatically configures the connection when enabled. The
media converter can also correct for wires swapped within a pair.
The media converter will adjust for up to 120ns of delay skew between the 1000Base-T pairs. |
| Smart Link Pass-Through |
When the Link Mode switch is placed
into Smart Link Pass-Through mode, the copper ethernet port will reflect
the state of the 1000Base-X media converter port. This feature can be
used whether fiber auto-negotiation is enabled or disabled. |
| Fiber Fault Alert |
With Fiber Fault Alert the state of
the 1000Base-X receiver is passed to the 1000Base-X transmitter. This
provides fault notification to the partner device attached to the
1000Base-X interface of the media converter. If the 1000Base-X
transmitter is off as a result of this fault it will be turned on
periodically to allow the condition to clear should the partner device
on the 1000Base-X be using a similar technique. This eliminates the
possibility of lockouts that occur with some media converters. Applies
only when fiber auto-negotiation is disabled. |
| 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 media converter
supports pause negotiation on the 10/100/1000Base-T connection and
1000Base-X fiber connection. |
| Duplex |
Full and half duplex operation supported. |
| Jumbo Packets |
Transparent to jumbo packets up to 10KB. |
| VLAN |
Transparent to VLAN tagged packets. |
| Remote Loopback |
Capable of performing a loopback on the 1000Base-X fiber interface. |
