Response to
Query
CnC-APC State
(continued)
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
CnC-APC Max
Power Level
Increase
APL= 3 bytes Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Sets or returns CnC-APC maximum power level increase, limited by Tx power
level, in the form xx.x, where:
xx.x = value from 0.0 to 9.9 dB,.
Example: <0/APL=3.9 (APC max power level increase is 3.9 dB.)).

CnC-APC
Home State
AHS= 12 bytes Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Note: Command is only for Offline unit, sent by switch in a 1:N Redundancy
system, or Online unit in a 1:1 Redundancy system.
Returns CnC-APC home state parameters in the form a,bbb,cc,ddd, where:
a = APC state. (1 = APC is active, 0 = APC is not active)
bbb = APC home state Tx power, in 0.1dB. (minus sign assumed)
cc = APC home state max power level increase, in 0.1 dB.
ddd = APC Tx power threshold, in 0.1 dB. (minus sign assumed)
Example: <0/AHS=1,100,60,085 (APC is active, home state power is -10.0 dB,
home state max power level increase is 6.0 dB, power threshold is -8.5 dB)

ACM Remote
Signal Noise Ratio
N/A 4 bytes Query only.
Returns the value of SNR of the remote demod in the form xx.x, where:
99.9 = Demod is unlocked.
xx.x = Not in IP-ACM.
Example: <0/RSN?
>0/RSN=12.4
N/A RSN? RSN=xx.x
