C.2.3 Defaults by Card
• Physical Layer thresholds—(OC3-8, OC-192, OC-192XFP, MRC-2.5G-4, and MRC-12 cards)
Expressed in percentages; includes optics thresholds.
Threshold defaults are defined for near end and/or far end, at 15-minute and one-day intervals.
Thresholds are further broken down by type, such as Section, Line, STS, or VT for performance
monitoring (PM) thresholds, and TCA (warning) or Alarm for physical thresholds. PM threshold types
define the layer to which the threshold applies. Physical threshold types define the level of response
expected when the threshold is crossed.
Note For full descriptions of the thresholds you can set for each card, see Chapter 15, “Performance
Monitoring.”
Note For additional information regarding PM parameter threshold defaults as defined by Telcordia
specifications, refer to Telcordia GR-820-CORE and GR-253-CORE.
C.2.3 Defaults by Card
In the tables that follow, card defaults are defined by the default name, its factory-configured value, and
the domain of allowable values that you can assign to it.
Note Some default values, such as certain thresholds, are interdependent. Before changing a value, review the
domain for that default and any other related defaults for potential dependencies.
