Cisco ONS 15310-MA SDH Card Default Settings
Note PPM (SFP) slots and ports are unassigned by default. You can optionally use the Defaults editor to
change these defaults to automatically assign PPM slots to take a single-port PPM, and to automatically
assign PPM port STMN rates. However, use discretion in changing the default PPM port rate in cases
where single-rate PPMs might be inserted in a card, since preprovisioned PPM port rates that are applied
to a single-rate PPM of the wrong rate will result in a mismatch of equipment and software.
Note For further information about the supported features of each individual card, see Chapter 2, “Card
Reference.”For further information about the supported features of Ethernet cards, consult the
Cisco ONS 15310-CL and Cisco ONS 15310-MA Ethernet Card Software Feature and Configuration
Guide.
C.3.2 Threshold Defaults
Threshold default settings define the default cumulative values (thresholds) beyond which a TCA will
be raised, making it possible to monitor the network and detect errors early.
Card threshold default settings are provided as follows:
• PM thresholds—(15310E-CTX-K9, E1_21_E3_DS3_3, and E1_63_E3_DS3_3 cards) Applicable to
E1, DS3, E3, and STMN ports. Can be expressed in counts or seconds; includes line, electrical, and
SDH thresholds.
• Physical Layer thresholds—(15310E-CTX-K9 cards only) Applicable to STMN ports. 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, VC high-order path, or VC low-order
path for 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 11, “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.3.3 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.
