Network Element Defaults
Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
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 15454. It includes descriptions of card, node, and Cisco Transport Controller (CTC) default
settings. To import, export, or edit the settings, see Chapter 13, “Maintain the Node.” 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), see Chapter 5, “Provision
Transponder and Muxponder Cards.” To change node settings, see Chapter 10, “Manage the Node.”
Note Unless otherwise specified, in this appendix “ONS 15454” refers to both ANSI (ONS 15454 SONET)
and ETSI (ONS 15454 SDH) shelf assemblies.
D.1 Network Element Defaults Description
The NE defaults are preinstalled on each Cisco ONS 15454 TCC2 and TCC2P card. They also ship as a
file called 15454-defaults.txt (ANSI shelves) or 15454SDH-defaults.txt (ETSI shelves) on the CTC
software CD in case you want to import the defaults onto existing TCC2/TCC2P cards. The NE defaults
include card-level, CTC, and node-level defaults.
Changes to card provisioning made manually using Change Card Settings procedures in Chapter 5,
“Provision Transponder and Muxponder Cards.”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
