Paradise P300 Change, Tx, Modulator, Aupc Mode Menu Modes are as follows, MON Dist, Self MON

6.6.18 Change, Tx, Modulator, AUPC, MODE Menu

Set AUPC Mode: [Off]

1=Off 2=Mon dist' 3=Maint' EbNo 4=Self mon

Change, Tx, Modulator, AUPC Mode Menu

NOTE: You probably need permission from the satellite operators to use AUPC unless you have a blanket power budget which you may use as you see fit.

The modes are as follows:

OFF	The modem disables the Auto Uplink Power Control, the Tx power will not adjust
	dynamically. Any AUPC positive or negative delta power adjustment to the Tx
	output power It is removed instantaneously (ie a Tx power step). Any bandwidth
	within the ESC channel used by the AUPC It is released back for ESC usage.
MON DIST'	The local modem utilises the async ESC channel between the local and distant
	modems to regularly collect Eb/No and BER data from the distant modem. This
	can be displayed with Monitor, Distant Eb/No & BER. This It is not an `active`
	AUPC mode and the Tx power will not adjust dynamically, it simply allows local
	monitoring (and logging) of distant performance.
MAINT Eb/No	This It is full AUPC mode. As with MON DIST' above it uses the ESC channel to
	collect Eb/No information from the distant modem, but in addition it varies the Tx
	power within the constraints provided to maintain a specified distant Eb/No.
SELF MON	This It is ONLY used in Tx only applications (typically point to multipoint) to
	attempt to maintain the Eb/No at (multiple) Rx only stations. It requires the
	modem to be able to receive the its own carrier via satellite (not by any form of IF
	loop). In operation it monitors the local Rx Eb/No and adjusts the local Tx power
	to keep this local Eb/No constant. This means it can compensate for atmospheric
	changes which affect the Tx signal to the satellite, and LOCAL atmospheric
	changes affecting the Rx signal from the satellite. If however (as It is common)
	there are multiple Rx terminals over a wide geographical area, then different
	atmospheric conditions over each terminal will still cause a variation in the Eb/No
	for each terminal.

Note: See AUPC in section 8.11.1 on page 154 regarding the async ESC channel requirements in order for local modem to distant modem communications in order for modes `Mon Dist` and `Maint Eb/No` to operate. Note also that the distant modem must be set for remote reporting of Eb/No with Change, Rx,

Demod, AUPC.

6.6.19 Change, Tx, Modulator, AUPC, MAX Menu

Set AUPC max positive delta power

[3.5dB] (0-25.0dB) ??.?dB (Yes)

Change, Tx, Modulator, AUPC, Max Menu

This allows the maximum additional power that the AUPC can use to maintain the distant Eb/No to be set. Set this so that the total maximum power (ie the nominal power set with Change, Tx, Mod, Power PLUS the AUPC Max positive delta power) It is within the constraints put upon your carrier by the satellite operators.
