PM measures (more information)
A PM measure consists of recording, during a preset time range (observation period), the values of specific parameters.
Some threshold limits have been assigned to such control parameters (the setting of the thresholds can be changed).
The exceeding of the threshold limit points out a more or less serious degradation of the signal. This con-dition generates an alarm.
The alarms relevant to the threshold exceeding are treated by the equipment and by the application as normal alarms. The only exception is that the alarm is not automatically reset at the return into the thresh-old limit but the user has to execute the reset of this kind of alarms.
The control parameters under examination change according to the equipment type and to the measure type supported by that type of equipment. Usually, all the executed measures refer to ITU-T Recommen-dations (for instance G.828, G.826, etc.).
The activation (and the deactivation) of the PM measures can be executed only after a command forwarded by the user.
When it has been activated a PM measure, the main controller of the equipment starts the storing of the values relevant to the control parameters. The results of the measures are sub-divided into records. Each record contains the values recorded into a specific time range (observation period).
If at the end of the observation period, the measure has not yet been deactivated the system starts another observation period and so on until when the operator stops the measure.
The equipment group the results of the PM measures into observation period of 15 minutes (primary records) and of 24 hours (daily records).
The observation periods can not be synchronized with the instant when the measure is activated but such records refer, for the primary records, to the quarter of an hour of the solar day (00.00, 00.15, 00.30, etc.) and, for the daily records, to the time 00.00 of the solar day.
For instance, if a measure starts at 11.40, the first primary record will have as observation period the time 11.40...11.45 (corresponding to the time range 11.30...11.45), while the first daily record will have as ob-servation period 11.40...00.00.
When the user requires the display of the results of the PM measures, the daily and primary records rele-vant to the running PM measures are displayed.
For each type of measure, the equipment keeps stored the current records and also the last 16 primary records (corresponding to the last 4 hours) and the last daily one (corresponding to the preceding day).
The preceding records are overwritten.
When the operator stops a measure, the system stores the uncompleted current record.
If the operator activates and deactivates the measure more times during the same observation period, the system will store the record that contains the results of the last executed measure.
For instance if the measure has been activated at 9.02 and deactivated at 9.07, then it has been newly activated at 9.09, the record relevant to the observation period 9.00...9.15 will contain the results of the measures relevant to the period 9.09...9.15, while the ones relevant to the period 9.02...9.07 will not be stored.
If an equipment has some PM measures on progress and it is re-started up or turned off, when it will suc-cessively restarted or turned on the measures activated before the turning off will be automatically re-started.
The records (primary and daily), relevant to the period when measure has been stopped, will result empty and when it has been reached the limit of 16 primary records and 1 daily one, they will overwrite the pre-ceding records.
