There are two modes of AUPC location:
AUPC between two
modems Maintains a target Eb/No programmed into the modem at each
end.

carrier from the satellite.
The menu below is enabled by selecting Local Modem AUPC = ON, located under the
Utility: Modem Type menu. This menu sets the AUPC parameters for both the self
