ID	Name	Meaning
1	Subrack No.	SubRack Number
2	Physical slot No.	Physical slot Number
3	CPU No.	CPU Number
4	Process No.	Process Number
5	Alarm Attribute	0=Normal, Alarms period are longer than the Transient Threshold. 1=Transient Count, The times and the period of the alarms whose periods are shorter than the Transient Threshold are summed up. If the sum result is longer than the Alarm Occurrence Period Threshold or Alarm Occurrence Times Threshold, an alarm so called Transient Count Alarm is triggered. Because Transient Count Alarm is based on accumulative result, the recovery of the alarm may occur at least one Summing Cycle later. The Summing Cycle can be query by MML "LST STATSLDWIN".

The time displayed on the LMT device panel is inaccurate and the time of the alarm and traffic statistics is incorrect.
