the local demodulator has unlocked, also resulting in no Es/No
information being available from the distant modem. In this situation,
because there is no carrier being received from the distant modem, you
may, for example, want to set the AUPC uplink level from the local
modem to its nominal level since there is no indication in this scenario of
a problem with the distant modem receiving the local modem’s carrier.
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.
