Defaults


Use the Defaults subtab to view the default settings for the ONS node. The subtab provides descriptions of node and card default settings and allows you to edit, import, and export the settings.

The defaults are preinstalled on each ONS node control card, such as the TSC for the ONS 15600, TCC2 or TCCP card for the ONS 15454, XTC for the ONS 15327, and the 15310-CL-CTX for the ONS 15310-CL. They also ship as node-defaults.txt file on the CTC software CD in case you want to import the defaults onto existing control cards. The node defaults include card-level and node-level defaults, as well as defaults that affect CTC.

Most of the defaults provide initial values for cards (when plugged in or preprovisioned), ports, protection groups, cross-connects, and SONET paths (at creation time). Changes made to these entities after creation override the settings without changing the defaults. Likewise, changing such defaults does not affect existing entities. If you change the settings on the Defaults subtab, either by editing them directly or by importing a new defaults file, the new defaults take effect immediately for all ONS node node settings except:

CTC defaults changes take effect when CTC is restarted. For more information about individual NE defaults, refer to the ONS node defaults documentation.

Item

Description

Defaults Selector

Displays an expandable, collapsible defaults tree. Clicking a tree item displays the item's defaults, for example, clicking an individual card displays the card's defaults in the Default Name and Default Value columns.

Default Name
