Manual card provisioning overrides default settings. Manual changes are those made using procedures 
in the chapters “Provision Transponder and Muxponder Cards” and “Change DWDM Card Settings” in 
the Line Card Configuration guide. If you use the CTC Defaults editor (on the node view Provisioning 
> Defaults tabs) or import a new defaults file, any changes to card or port 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] or multiplex section-shared protection ring [MS-SPRing] reversion time, 
BLSR/MS-SPRing ring revertive, BLSR/MS-SPRing span reversion time, BLSR/MS-SPRing span 
revertive, y cable revertive or reversion time, splitter revertive or reversion time). Settings relating to 
protection apply to subsequent provisioning.

Changing some node-level provisioning through NE defaults can cause CTC disconnection or a 
reboot of the node in order for the provisioning to take effect. Before you change a default, check 
in the Side Effects column of the Defaults editor (right-click a column header and select 
Show Column > Side Effects) and be prepared for the occurrence of any side effects listed for 
that default.

The information in this section pertains to the default settings for each DWDM, Transponder (TXP), 
Muxponder (MXP), or Ethernet card. Cisco provides several types of user-configurable defaults for 
DWDM, TXP, MXP, and Ethernet cards. Types of card defaults can be broadly grouped by function, as 
outlined in the following subsections. For information about individual card settings, see the chapters 
“Provision Transponder and Muxponder Cards” and “Change DWDM Card Settings” in the Line Card 
Configuration guide. 

When the card level defaults are changed, the new provisioning done after the defaults have changed is 
affected. Existing provisioning remains unaffected.

The following types of defaults are defined for DWDM, TXP, MXP, and Ethernet cards.

Most card-level and port-level configuration defaults correspond to settings found in the CTC card-level 
Provisioning tabs. 

The full set of Automatic Laser Shutdown (ALS) configuration defaults can be found in the CTC 
card-level Maintenance > ALS tab for supported cards. ALS defaults are supported for OSCM, 
OSC-CSM, OPT-BST, OPT-BST-L, ADM-10G, GE_XP, 10GE_XP, TXP,

 

MXP, OTU2-XP, and PSM 

cards. For information on how ALS card settings achieve network level optical safety, see the chapters 
“Setup Optical Service Channel Cards”, “Optical Amplifier Cards”, or “Provision Transponder and 
Muxponder Cards” in the Line Card Configuration guide.
