DLP-D73 Create a 1+1 Protection Group
| Purpose | This task creates a 1+1 protection group for any STM-N card/port (STM-1, |
| | STM-1-8, STM-4, STM-4-4, STM-16, STM-16 AS, and STM-64). |
| Tools/Equipment | Installed STM-N cards or preprovisioned slots |
| Prerequisite Procedures | DLP-D60 Log into CTC, page 3-24 |
| Required/As Needed | As needed |
| Onsite/Remote | Onsite or remote |
| Security Level | Provisioning or higher |
| |
Step 1 | Verify that the cards are installed according to the 1+1 requirements specified in Table 4-3 on page 4-27. |
Step 2 | In node view, 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+1 from the drop-down menu.
•Protect Port—Choose the protect port from the drop-down menu. The menu displays the available STM-N ports. If STM-N cards are not installed, no ports appear in the drop-down menu.
After you choose the protect port, a list of ports available for protection appear under Available Ports. If no cards are available, no ports appear. If this occurs, 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 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 6 Complete the remaining fields:
•Bidirectional switching—Select this check box if you want both Tx and Rx signals to switch to the protect port when a failure occurs to one signal. Leave it unchecked if you want only the failed signal to switch to the protect port.
•Revertive—Select this check box if you want traffic to revert to the working card after failure conditions stay corrected for the amount of time entered in the Reversion Time field.
•Reversion time—If Revertive is checked, 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. Reversion time 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.
Step 8 Return to your originating procedure (NTP).
