Statistic RMON Object or Calculation
Error Rate Total Errors divided by Total PDUs; lets you compare
errors seen by multiple data sources regardless of the
cell rate.
Estimated Up Time
Estimated Down Time
The estimated up or down time of this PVC, based on
monitoring PVC activity and LMI status messages.
May not equal the interval duration; the probe was
unsure of the state in the unaccounted for time.
