6.2.3.4 Maximum Negative AUPC Power Offset
Range: 0dBm to 25.0dBm; step size: 0.1dBm
Description: This is the maximum decrease in Tx power level that AUPC is allowed to
make in order to maintain remote Eb/No.

6.2.3.5 AUPC Method
Normal This should be selected when Q-Series, Quantum or Evolution modems
are being used at either end of the satellite link.
Self In this mode, the modem will adjust power output in an attempt to
maintain the Eb/No at its target level using the Eb/No from its own
received carrier rather than the Eb/No value being passed back from any
remote modem.
P300 This should be selected when interoperating with a P300-series modem.
Table 6-25 AUPC Method
6.2.3.6 Carrier Loss Action
Set to
Nominal
The AUPC delta power is set to zero, causing the carrier to return to its
nominal power level.
Freeze at
current value
The carrier power is frozen at its current value.
Set to max The AUPC delta power is set to the maximum power limit as defined by
Maximum AUPC power offset.

6.2.3.7 Local Demod Unlocked Action
Off When set to Off, then the Local demod unlocked action has no effect and
only the Carrier loss action is used.
The distinction between the two carrier loss actions is as follows: The
Carrier loss action covers the situation where the distant modem’s
demodulator has unlocked, resulting in no Es/No information being
available from the distant modem. In this situation, you may, for example,
want to increase the AUPC uplink level from the local modem to the
maximum. The Local demod unlocked action covers the situation where
