Response to
Query
CnC-APC
Frame Error
Rate
N/A 4 bytes Query only.
Valid only in CDM-570A Compatible Mode (CMO=1).
Returns the value of CnC-APC FER in the form xE -c , where:
x = value
E -c = Exponent.
Returns 9999 if modem is not in CnC-APC mode or if there is an APC frame sync
error.
Example: <0/AFE?
>0/AFE=8E-2
N/A AFE? AFE= xE - c (see
Description of
Arguments)
CnC-APC FER
Reset
AFR= None Command only.
Valid only in CDM-570A Compatible Mode (CMO=1).
This command takes no arguments.
Restarts CnC-APC FER measurement.
AFR= N/A N/A
CnC-APC
Activate/Suspend
APC= 1 byte, 0 thru 2 Command only.
Valid only in CDM-570A Compatible Mode (CMO=1).
Activates or suspends APC operation in the form 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.
Valid only in CDM-570A Compatible Mode (CMO=1).
Returns the state of APC operation 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
N/A APS? APS=xx
