Description

    • Auto copper downshift. Automatically detects a 2-pair cable environment and downshifts operation of the link to 100 Mbps. Configure the number of times (0-8) that the PHY will attempt to establish a successful gigabit link before attempting to "downshift" as an auto-negotiating 10/100 device.
    • 10BaseT extended distance. Normal/extended - default normal. By configuring as "extended", the 10baseT receiver sensitivity is increased providing the possibility of a 10BaseT connection greater than 100 m.
    • 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.
    • Unknown unicast frame filtering. When enabled, unicast frames with an unknown destination address are not allowed to egress the port.
    • Auto-negotiation (802.3u). The media converter supports auto negotiation. The 1000Base-X fiber interface negotiates according to 802.3 clause 37. The 10/100/1000 Base-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 until the copper is linked up and the HCDs match.
    • Configuration mode selection. Select whether to use the on-board DIP switches or the management software for mode selection.
    • Unknown multicast frame filtering. When enabled, multicast frames with an unknown destination address are not allowed to egress the port.
    • Auto-MDIX. Auto-MDIX (automatic medium-dependant interface crossover) detects the signaling on the copper Ethernet interface to determine the type of cable connected and automatically configures the connection when enabled. The media converter can also correct for wires swapped within a pair.
    • Detailed port statistics. To assist in troubleshooting copper and fiber links, an extensive list of ingress and egress counters for both copper and fiber ports are available. These statistics can be viewed locally via the management module or from a central SNMP NMS on the network.
    • Unidirectional Ethernet. When enabled, provides the ability to restrict port to one-way traffic flow. Used in applications such as unidirectional video broadcasting as well as providing security for Ethernet connections in accessible public areas.
