The total amount of time in one-hundreds of a second that the probe is sure this LCI was active, i.e., the total time the value of wanFrPvcStatsState was equal to up(1). A value of less than the age of this entry does not necessarily mean that this LCI was down. It only means the probe was not certain it was up. Note: the sum of wanFrPvcStatsUpTime and wanFrPvcStatsDownTime may be less than the age of this entry. In this case, the unaccounted for time is the time the probe was uncertain of the state of this DLCI, i.e., the total time the value of wanFrPvcStatsState was unknown(3).
