3.10 Setting Up Protection Groups

The ONS 15327 provides several card protection methods. When you set up protection for ONS 15327 cards, you must choose between maximum protection and maximum card-slot availability. The highest protection reduces the number of available card slots; the highest card-slot availability reduces the protection. For a description of protection groups refer to the “Card Protection” section on page 2-2.

For the ONS 15327, a 1:1 (electrical) XTC protection group is pre-provisioned. The name of the protection group is XTCPROTGRP and it cannot be edited or deleted. Therefore, you only need to create protection for optical cards.

Procedure: Create Protection Groups for Optical Cards

Step 1 From the CTC node view, click the Provisioning tab.

Step 2 Click the Protection subtab.

Step 3 Under Protection Groups, click Create.

Step 4 In the Create Protection Group dialog box (Figure 3-19),enter the following:

•Name—Type a name for the protection group, up to 32 alpha-numeric characters.

•Type—Choose 1+1 as the protection type. The protection selected determines the ports that are available to serve as protect and working ports.

•Protect Entity—Choose protect port from the list.

Based on these selections, a list of available working ports displays under Available

Entities. Because 1:1 protection is pre-provisioned, no cards appear under available cards.

Step 5 From the Available Entities list, choose the port that you want to provision as the working port. This port will be protected by the port you selected in Protect Entity. Select the top arrow button to move it to the Working Entities list. You can move more than one port.

Step 6 Complete the remaining fields:

•Bidirectional switching—(optical cards only) if checked, both transmit and receive channels switch if a failure occurs to one.

•Revertive—if checked, the ONS 15327 reverts back to the working port after failure conditions are corrected.
