DLP-A34 Create an Optimized 1+1 Protection Group
Step 1 Verify that the cards are installed according to the optimized 1+1 requirements specified in Table 4-1 on
page 4-10.
Step 2 Change the port type from SONET to SDH for each applicable port on the OC3 IR 4/STM1 SH 1310 or
OC3 IR/STM1 SH 1310-8 card where you want to provision a 1+1 optimized protection group:
a. In node view, double-click the applicable card.
b. Click the Provisioning > Line tabs.
c. In the Type column next to port, choose SDH from the drop-down list and click Apply.
Step 3 In node view, click the Provisioning > Protection tabs.
Step 4 In the Protection Groups area, click Create.
Step 5 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+1 Optimized from the drop-down list.
• Protect Port—Choose the protect port from the drop-down list. The list displays the available
OC3 IR 4/STM1 SH 1310 or OC3 IR/STM1 SH 1310-8 ports. If OC3 IR 4/STM1 SH 1310 or
OC3 IR/STM1 SH 1310-8 cards are not installed, no ports appear in the drop-down list.
After you choose the protect card, a list of cards available for protection appear in the Available Ports
list, as shown in Figure 17-34 on page 17-82. If no cards are available, no cards appear. If this occurs,
you cannot complete this task until you install the physical cards or preprovision the ONS 15454 slots
using the “DLP-A330 Preprovision a Slot” task on page 20-20.
Step 6 From the Available Ports list, choose the port that will be protected by the port you selected in the
Protect Port field. Click the top arrow button to move each port to the Working Ports list.
Step 7 Complete the remaining fields:
