• When you do not enable AUPC, both maximum and average TPLI shows ‘0.0'.
Examples: 08.0,13.5,2.5,1.8 means:
Minimum E
b
/N
0
observed in the measurement interval = 8.0 dB
Average E
b
/N
0
observed in the measurement interval = 13.5 dB
Maximum TPLI observed in the measurement interval = 2.5 dB
Average TPLI observed in the measurement interval = 1.8 dB
Loss,04.5,0.0,0.0 means:
There was a loss of demod lock during the measurement interval
Average E
b
/N
0
observed in the measurement interval = 4.5 dB
Maximum TPLI observed in the measurement interval = AUPC disabled
Average TPLI observed in the measurement interval = AUPC disabled
The presentation of statistics information varies slightly when in VersaFEC ACM (IP-ACM) or
VersaFEC-2 ACM (V2-ACM) mode.
In VersaFEC ACM (IP-ACM) mode:
Sta198:02/11/13 10:37:32
16.0,16.0,2,4,0,0 (▲ ▼)
The bottom line calculates and then displays statistics data as follows:
Example: 16.0,16.0,2,4,0,0 means:
Minimum E
b
/N
0
observed in the measurement interval = 16.0 dB
Average Eb/N0 observed in the measurement interval = 16.0 dB
The Rx ModCod, in hex format, that was current when the entry was logged = 2
Maximum Rx ModCod, in hex format, during the measurement interval = 4
Minimum Rx ModCod, in hex format, during the measurement interval = 0
Number of Rx ModCod changes, in hex format, during the measurement interval = 0
