Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX “tells” the device at the other end
of the segment what its capabilities are. The capabilities of a port (25 or
26) with an FE-100TX installed are 10BASE-T, 10BASE-TFD (full
duplex mode), 100BASE-TX and 100BASE-TXFD (full duplex mode).
In normal operation, with all capabilities enabled, the FE-100TX
“advertises” that it has the ability to operate in any mode. The Network
Manager may choose to set up the port so that only a portion of the
available capabilities are advertised and the others are disabled. For
example, only 100BASE-TX and 100BASE-TXFD might be enabled so
that only devices that operate at 100 Mbps can communicate with that
port.
