Description: The ap553 Line Statistics 24 hour history table. This table is comprised of 96 objects, each of which hold T1 Line statistics data for a 15 minute time period. Upon power up or after a reset, data is collected in the current interval object: ap553CurrentLineStats. After 15 minutes this data is moved into the first of 96 historical objects. After each sub- sequent 15 minute period completes, data is moved downstream, data from interval #1 is moved into interval #2, etc. The number of valid history intervals contained in ap553ValidLineStatsIntervals is incremented. The ap553TotalLineStats object is recalculated after each 15 minute interval completes, summing all valid interval data into this object. When all 96 objects have been filled, containing 24 hours of data, the oldest object, #96, will be overwritten by object #95, at the completion of the next 15 minute interval. In this fashion, the unit is able to maintain a current 24 hour history of Line Statistics data.
