This read-write object enables or disables AUPC (Automatic Uplink Power Control): disable(0) or enable(1), with an explicit note that framing must first be enabled before AUPC can be turned on. AUPC lets this unit's transmitter automatically raise power during signal fades, as reported by the remote demodulator's Eb/No via cdm570AUPCRemoteDemodTargetEbNo, to maintain link quality without manual intervention, so enabling it is what lets a link automatically compensate for rain fade rather than requiring an admin to manually adjust cdm570TxPowerLevel during every weather event. On a link in a rain-prone region where signal fades are common, an admin would enable AUPC, after first confirming EDMAC framing is active, so the transmitter automatically compensates during storms rather than requiring manual power adjustments each time.
