| Auto-Negotiation (802.3ab) |
The media converter supports auto
negotiation. The 1000Base-X fiber interface negotiates
according to 802.3 clause 37. The 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 with Skew Correction |
Auto-MDIX (automatic medium-dependant interface
crossover) detects the signaling on the 1000Base-T
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 64ns 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 1000BASE TX 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 802.3x) |
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 1000Base-T fiber 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. |
