Threshold Reference

Thresholds are used to set error levels for each PM. You can program PM threshold ranges from the
Provisioning > Threshold tabs on the card view. For procedures on provisioning card thresholds, such as
line, path, and SONET thresholds, see the Card Provisioning chapter.
During the accumulation cycle, if the current value of a performance monitoring parameter reaches or
exceeds its corresponding threshold value, a TCA is generated by the node and sent to CTC. TCAs
provide early detection of performance degradation. When a threshold is crossed, the node continues to
count the errors during a given accumulation period. If 0 is entered as the threshold value, the
performance monitoring parameter is disabled.

Selected Interfaces: Clearing selected interfaces erases all PM counts associated with the selected
radio buttons at the NE level. This refers to the port-level data, STS-level data, and VT-level data.
Choosing this option will clear the entire set of displayed data at the NE level, rather than the
selected row.
All interfaces on port x: Choosing this option will clear data for all interfaces at the NE level,
including those not currently displayed, such as the ends, periods, and VTs.
All interfaces on card: Choosing this option will only clear the interfaces that apply to the selected
card at the NE.
