NTP-A47 Subtend a BLSR from a Path Protection
Step 5 Log into a path protection node that connects to the node in Step 3. (In Figure 5-12 on page 5-36, Node
4 is the only other node in the path protection.)
Step 6 Complete the “DLP-A377 Provision Section DCC Terminations” task on page 20-61 for each OC-N card
that will carry the path protection. Alternatively, if additional bandwidth is needed for CTC
management, complete the“DLP-A378 Provision Line DCC Terminations” task on page 20-62.
Step 7 Repeat Step 6 for each node in the path protection.
Step 8 As needed, complete the “DLP-A380 Provision a Proxy Tunnel” task on page 20-63.
Step 9 As needed, complete the “DLP-A381 Provision a Firewall Tunnel” task on page 20-64.
Step 10 From the View menu, choose Go To Network View to view the subtending rings.
Step 11 Complete the “NTP-A177 Path Protection Acceptance Test” procedure on page 5-22.
Stop. You have completed this procedure.
NTP-A47 Subtend a BLSR from a Path Protection
Step 1 In the path protection node that will subtend the BLSR, install the two OC-N cards that will serve as the
BLSR trunk (span) cards (in Figure 5-12 on page 5-36, Node 3, Slots 5 and 12). See the “NTP-A16
Install the OC-N Cards” procedure on page 2-6.
Step 2 Attach fibers from the cards in Step 1 to the BLSR trunk cards on another BLSR node or nodes. In
Figure 5-12 on page 5-36, Slot 5/Node 3 connects to Slot 12/Node 2, and Slot 12/Node 3 connects to
Slot 5/Node 1.
Step 3 Log into the ONS 15454 that will subtend the BLSR (the node in Step 1). See the “DLP-A60 Log into
CTC” task on page 17-66. If you are already logged in, continue with Step 4.
Step 4 Create the DCCs on both OC-N trunk cards (east and west) that will carry the BLSR. See the “DLP-A377
Provision Section DCC Terminations” task on page 20-61. Alternatively, if additional bandwidth is
needed for CTC management, complete the“DLP-A378 Provision Line DCC Terminations” task on
page 20-62.
Step 5 Create the subtending BLSR:
a. Complete the “NTP-A40 Provision BLSR Nodes” procedure on page 5-10 for each node that will
be in the BLSR. If you have already provisioned the BLSR, perform this procedure for the
subtending node only.
b. Complete the “NTP-A126 Create a BLSR” procedure on page 5-12. Include the node in Step 3 (the
node that will subtend the BLSR) in the BLSR.
Step 6 From the View menu, choose Go to the Network View to see the subtending ring.
Purpose This procedure subtends a BLSR from an existing path protection.
Tools/Equipment One path protection node must have OC-N cards and fibers to carry the
BLSR
