Unit returns the state of APC operation. Return value is in form xx, where:
00 = APC is not active
01 = No Solution
02 = OK - ReBalance Done
03 = OK(Partial) - CnC Ratio approaches limit
04 = OK(Partial) - Local power approaches miminum value (-25 dBm for IF band)
05 = OK(Partial) - Local power approaches minimum value (-40 dBm for L-Band)
06 = OK(Partial) - Local power approaches maximum value (0 dBm)
07 = OK(Partial) - Local power approaches limit set by max power level increase
08 = OK(Partial) - Distant power approaches miminum value (-25 dBm for IF band)
09 = OK(Partial) - Distant power approaches minimum value (-40 dBm for L-Band)
10 = OK(Partial) - Distant power approaches maximum value (0 dBm)
11 = OK(Partial) - Distant power approaches limit set by max power level increase
12 = OK(Partial) - Incomplete
13 = No APC Frame Sync
14 = CnC Ratio Problem
15 = Local EbNo too high
16 = Distant EbNo too high
17 = Distant End ReBalance failed
18 = Distant End NoResponse
19 = Fail-Calculate Mismatch
20 = CnC Ratio too high
21 = Please run again
22 = APC is active
23 = Local margin too low
24 = Distant margin too low
25 = Rx Data Rate<64kbps
26 = Tx Data Rate<64kbps
27 = Local RSL too low
28 = Distant RSL too low
