NTP-A224 Provision an Open-Ended Path Protection
Step 1 Verify that the fiber is correctly connected to the path protection trunk (span) OC-N cards at each
open-ended path protection node. Figure 5-11 shows an example. Node 1 is connected to ONS 15454
Nodes 2 and 3 through Slots 12 and 5. Trunk cards at Nodes 2 and 3 are connected to the third-party
vendor equipment.

Step 2
Verify that the third-party cards or units to which the ONS 15454 trunk cards are connected are the same
OC-N rate as the ONS 15454 trunk cards. The third-party time slots must match the ONS 15454 card
time slots to which they are connected. For example, if your trunk card is an OC-48, the third-party
vendor card or unit must have STSs 1 to 48 available.
Step 3 Log into an ONS 15454 in the path protection you are turning up. See the “DLP-A60 Log into CTC”
task on page 17-66. If you are already logged in, continue with Step 4.
Step 4 Complete the “DLP-A377 Provision Section DCC Terminations” task on page 20-61 for the ONS 15454
cards/ports that are connected to another ONS 15454. (Alternatively, if additional bandwidth is needed
for CTC management, complete the“DLP-A378 Provision Line DCC Terminations” task on
