Provisioning

---

Use the Provisioning subtab to view wavelength division multiplexing (WDM) parameters calculated by the ONS 15454 SDH DWDM automatic node setup (ANS) function. ANS is a TCC2/TCC2P function that adjusts values of the variable optical attenuators (VOAs) on the DWDM channel paths to equalize the per-channel power at the amplifier input. This power equalization means that when the ONS 15454 SDH DWDM network is launched, all the channels have the same amplifier power level, independent from the input signal on the client interface and independent from the path crossed by the signal inside the node.

On the Provisioning subtab, you can view, edit, and export all ONS 15454 SDH DWDM parameters. You can also export the parameters to a text file, where they can be imported to other nodes, and you can import parameters that are stored in a text file. All parameters can be edited with CTC, either through the WDM-ANS > Provisioning tab or through the Provisioning tab in card view.

The DWDM network types are:

• Metro-Core: Channels are equalized.

• Metro-Access: Channels are not equalized (minimizes the number of amplifiers needed in the ring).

• Not-DWDM: An SDH or hybrid network.

The ANS parameters for the node's east and west sides are the following:

Item	Description
Selector	Displays the DWDM network components in a tree structure. Choosing a component displays its parameters and parameter values.
Parameter	Lists the DWDM parameters in a notational string format.
Value	Sets the value of the parameter. You can change the value by using the drop-down list or typing in the field.
Apply	Applies any changes that were made to DWDM node parameters.
Reset	Cancels NE Update subtab changes and returns the fields to their last-saved settings.
Help	Displays context-sensitive help.
