Unit returns the oldest five Stored Statistics (including newly added Minimum and Average Rx Signal Level
(RSL)), which have not yet been read, in the form [CR]sub-body[CR]sub-body[CR] sub-body[CR]sub-
body[CR]sub-body, where:
•
For all non-ACM modes, the statistics sub-body is defined as
AA.ABB.BC.CD.DEE.E,FF.Fddmmyyhhmmss where:
AA.A=Minimum Eb/No during sample period.
BB.B=Average Eb/No during sample period.
C.C=Maximum Tx Power Level Increase during sample period.
D.D=Average Tx Power Level Increase during sample period.
EE.E=Negative value of Minimum Rx Signal Level (RSL) in dB during sample period.
FF.F=Negative value of Average Rx Signal Level (RSL) in dB during sample period.
ddmmyy = date stamp.
hhmmss = time stamp.
•
In VersaFEC ACM (IP-ACM) mode the statistics sub-body is defined as
AA.ABB.BC,DG,HEE.E,FF.Fddmmyyhhmmss, where:
AA.A=Minimum SNR during sample period.
BB.B=Average SNR during sample period.
C=Current IP-ACM Rx ModCod when the statistic entry was logged.
D=Maximum Rx ModCod in hexadecimal during sample period.
G=Minimum Rx ModCod in hexadecimal during sample period.
H=Number of Rx ModCod changes in hex format during sample period.
EE.E=Negative value of Minimum Rx Signal Level (RSL) in dB during sample period.
FF.F=Negative value of Average Rx Signal Level (RSL) in dB during sample period.
ddmmyy = date stamp.
hhmmss = time stamp.
•
In VersaFEC-2 ACM mode, the statistics sub-body is defined as
AA.ABB.BCC,DD,EE.E,FF.Fddmmyyhhmmss, where:
AA.A=Minimum SNR during sample period.
BB.B=Average SNR during sample period.
CC=Maximum Rx ModCod in decimal during sample period.
DD=Minimum Rx ModCod in decimal during sample period.
EE.E=Negative value of Minimum Rx Signal Level (RSL) in dB during sample period.
FF.F=Negative value of Average Rx Signal Level (RSL) in dB during sample period.
ddmmyy = date stamp.
hhmmss = time stamp.
NOTES:
1)
If there are less than five retrievable statistics, the remaining positions are padded with zeros.
2)
If there are no new events, the unit replies with RNN*.
3)
Do not mix use of RNN and RNS. Comtech EF Data recommends that you use the RNN query
instead of the legacy RNS query. RNN includes all information provided in RNS *PLUS* Rx Signal
Level (RSL). Since RNN and RNS use the same index system for statistics entries, if users mix use
of the two queries, the statistics entries won't be displayed sequentially by either RNN or RNS. For
this reason, or if you change your operating mode between Non-ACM and ACM (IP-ACM or V2-
ACM) modes, Comtech EF Data recommends that you execute the Clear All Stored Statistics
(CAS=) command before retrieving any further statistics.
