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 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.
