Desired Oper. Mode (Selectable)
This field allows the user to select the desired operational mode for an
interface in port 25 or 26. The field toggles between 100BASE-FX and
100BASE-FXFD (full duplex) when an DELFX-UI or DELF3-UI is
installed. Section 5.23.1 describes how to configure a port with an
DELFX-UI or DELF3-UI.

Advertised Ability (Selectable)
During auto-negotiation, the DELTX-UI “tells” the device at the other end
of the segment what its capabilities are. The capabilities of a port (25 or
26) with an DELTX-UI 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 DELTX-UI
“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
