Additional IE-iMcV-MediaLinX TX/SFP Features
Selective Advertising
Selective Advertising, when used in combination with Auto Negotiation,
advertises only the configured speed and duplex mode for the twisted pair
port. If a specific speed and/or duplex mode are desired, IMC Networks
recommends using Selective Advertising, rather than Force Mode, when
connecting to devices that only use Auto Negotiation.

Flow Control
Whether the copper port is configured for 10Mbps or 100Mbps, the only need for
flow control is to pass congestion at the customer's location back up to the fiber port.
If the copper port is supporting PAUSE due to the outcome of the Auto Negotiation
process, then congestion on the copper port will cause PAUSE frames to be sent out
the fiber port. In a like fashion, if congestion occurs on the fiber port, then the
copper port will send PAUSE if flow control is enabled on the copper port through
the outcome of Auto Negotiation. In half duplex mode, the unit will provide physical
"Back Pressure" for flow control instead of PAUSE.
Flow control can be disabled via a DIP Switch or through SNMP management. If
disabled, the copper port will not advertise a flow control capability. Flow control
should be enabled if the end device, such as a switch, also has flow control
capability, and it is enabled.
TX Duplex Mode
The Duplex Mode settings of the IE-iMcV-MediaLinX TX/SFP converter are offered on
DIP Switch #2: FDX:OFF, HDX:ON The default duplex mode for IE-iMcV-
MediaLinX TX/SFP is Full-Duplex. This mode is recommended if the End device does
not offer Auto Negotiation, or is not desired.
