Response to Query
CnC-APC BER
Reset
ABR= None Command only.
This command takes no arguments. Forces restart of the CnC-APC BER measurement.
ABR= N/A N/A
CnC-APC Frame
Error Rate
N/A 4 bytes Query only.
Returns the value of CnC-APC FER in the form xEc, where:
x=Value
Ec=Exponent
EXAMPLE: <0/AFE? >0/AFE=8E2 (indicates CnC-APC FER @ 8 x 10
-2
)
NOTE: Returns 9999 if modem is not in CnC-APC mode or there is an APC frame sync error.
N/A AFE? AFE=xxxx
CnC-APC FER
Reset
AFR= None Command only.
This command takes no arguments. Forces restart of the CnC-APC FER measurement.
AFR= N/A N/A
CnC-APC
Activate/Suspend
APC= 1 byte, 0 thru 2 Command only.
Used to activate or suspend APC operation, in format APC=x, where:
0=no action
1=Activate APC
2=Suspend APC
APC= N/A N/A
CnC-APC state N/A 2 bytes Query only.
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
N/A APS? APS=xx
