Network Element Defaults

The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
Note
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.
This appendix describes the factory-configured (default) network element (NE) settings for the
Cisco ONS 15600. It includes descriptions of card default settings and node default settings. For
procedures for importing, exporting and editing the settings, refer to the "Maintain the Node" chapter of
the Cisco ONS 15600 Procedure Guide. Cards supported by this platform that are not listed in this
appendix are not supported by user-configurable NE defaults settings.
To change card settings individually (that is, without changing the defaults), refer to the "Change Card
Settings" chapter of the Cisco ONS 15600 Procedure Guide. To change node settings, refer to the
"Change Node Settings" chapter of the Cisco ONS 15600 Procedure Guide.
C.1 Network Element Defaults Description
The NE defaults are preinstalled on each Cisco ONS 15600 TSC card. They also ship as a file called
15454-defaults.txt on the Cisco Transport Controller (CTC) software CD in the event you want to import
the defaults onto existing Timing and Shelf Controller (TSC) cards. The NE defaults include card-level,
CTC, and node-level defaults.
Changes to card provisioning made manually using Change Card Settings procedures in the
Cisco ONS 15600 Procedure Guide override default settings. If you use the CTC Defaults editor (in the
node view > Provisioning > Defaults tabs) or import a new defaults file, any changes to card or slot
settings that result only affect cards that are installed or preprovisioned after the defaults have changed.
Changes made manually to most node-level default settings override the current settings, whether
default or provisioned. If you change node-level default settings, either by using the Defaults editor or
by importing a new defaults file, the new defaults reprovision the node immediately for all settings
except those relating to protection (1+1 bidirectional switching, 1+1 reversion time, 1+1 revertive,
bidirectional line switched ring [BLSR] ring reversion time, BLSR ring revertive, BLSR span reversion
time, BLSR span revertive), which apply to subsequent provisioning.
