Provisioning or higher

Step 1 Verify that the cards are installed according to 1:N requirements specified in Table 4-3 on page 4-27.

Step 2 Click the Provisioning > Protection tabs.

Step 3 In the Protection Groups area, click Create.

Step 4 In the Create Protection Group dialog box, enter the following:

•Name—Type a name for the protection group. The name can have up to 32 alphanumeric (a-z, A-Z,

0-9) characters. Special characters are permitted. For TL1 compatibility, do not use question marks (?), backslash (\), or double quote (“) characters.

•Type—Choose 1:N from the drop-down menu.

•Protect Card—Choose the protect card from the drop-down menu. The menu displays E1-N-14 and DS3i-N-12 cards installed in Slots 4 or 17. If these cards are not installed, no cards appear in the drop-down menu.

After you choose the protect card, a list of cards available for protection appear under Available Cards. If no cards are available, no cards appear. If no cards are available, you cannot complete this task until you install the physical cards or preprovision the ONS 15454 SDH slots using the “DLP-D442 Preprovision a Slot” task on page 5-5 .

Step 5 From the Available Cards list, choose the cards that will be protected by the card selected in the Protect Card drop-down menu. Click the top arrow button to move each card to the Working Cards list.

Step 6 Complete the remaining fields:

•Bidirectional switching—Not available for 1:N protection.

•Revertive—Always enabled for 1:N protection groups.

•Reversion time—Click Reversion Time and select a reversion time from the drop-down menu. The range is 0.5 to 12.0 minutes. The default is 5.0 minutes. This is the amount of time that will elapse before the traffic reverts to the working card after conditions causing the switch are cleared.

Step 7 Click OK, then click Yes on the confirmation dialog box.

Step 8 Return to your originating procedure (NTP).
