6-32 OAM&P description

Performance monitoring

Performance monitoring (PM) refers to the continuous collection, analysis,
and reporting of the performance data of a monitored entity. This monitoring
allows early detection of service degradations and facilitates preventive
maintenance without interruption of service. PMs can also be used to facilitate
trouble/fault isolation.
The OME6130 monitors the following entities for PM collection:
•
•
•
•
•
The OME6130 craft user interface Performance application allows the user
to retrieve:

PM functions

PM functions include:
•
•
Count binning
Each monitored entity generates a set of PM parameter counts based on raw
data from hardware and other systems. These counts can be retrieved or reset
through user commands.
Thresholding
Performance thresholds are values associated with specific performance error
statistics. Aside from the physical PMs, each SDH performance parameter has
two thresholds which can be applied to either the current 15 minute or day
counts. When a PM parameter value exceeds its threshold settings, the system
generates a threshold crossing alert (TCA). TCAs are cleared when the PM
counts have been reset or the particular timed accumulation bin has
terminated.
PM thresholds management for the STM-1/4 interfaces is available from the
STM application in the Facility menu of the local craft access terminal.
