Turn Up a Network
Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
This chapter explains how to turn up and test Cisco ONS 15454 networks, including point-to-point networks, linear add-drop multiplexers (ADMs), path protection, and bidirectional line switched rings (BLSRs).

Prerequisite Procedures |
A175 Two-Fiber BLSR Acceptance Test or |
Required/As Needed |
As needed |
Onsite/Remote |
Onsite |
Security Level |
Provisioning or higher |
Note path protection is the default ONS 15454 topology. It is available as soon as you install the path protection OC-N cards, connect the OC-N fibers, and create the DCC terminations. Unlike the BLSRs, ONS 15454 path protection configuration do not require explicit setup.
Step 1 In the node that will subtend the path protection (Node 3 in Figure 5-12), install the two OC-N cards that will serve as the path protection trunk (span) cards (Node 3, Slots 6 and 13). See the "NTP-A16 Install Optical Cards and Connectors" procedure. If they are already installed, continue with Step 2.
Step 2 Attach fibers from these cards to the path protection trunk cards on the neighbor path protection node or nodes. In Figure 5-12, Node 3/Slot 6 connects to Node 4/Slot 13, and Node 3/Slot 13 connects to Node 4/Slot 6.
Figure 5-12 Path Protection Subtended from a BLSR
Step 3 Complete the "DLP-A60 Log into CTC" task at the ONS 15454 that will subtend the path protection (Node 3 in the example).
Step 4 Complete the "DLP-A377 Provision Section DCC Terminations" task 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.
Step 5 Log into a path protection node that connects to the node in Step 3. (In Figure 5-12, Node 4 is the only other node in the path protection.)
Step 6 Complete the "DLP-A377 Provision Section DCC Terminations" task 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.
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.
Step 9 As needed, complete the "DLP-A381 Provision a Firewall Tunnel" task.
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.
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, Node 3, Slots 5 and 12). See the "NTP-A16 Install Optical Cards and Connectors" procedure.
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, 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. 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. Alternatively, if additional bandwidth is needed for CTC management, complete the "DLP-A378 Provision Line DCC Terminations" task.
Step 5 Create the subtending BLSR:
a. Complete the "NTP-A40 Provision BLSR Nodes" procedure 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. 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.
Stop. You have completed this procedure.
NTP-A48 Subtend a BLSR from a BLSR
Note This procedure assumes that all nodes are configured for the BLSR. If you need to add a node to a BLSR, see the "NTP-A345 Add a BLSR Node" procedure.
Step 1 Complete the "DLP-A60 Log into CTC" task at the node that will subtend the BLSR (Node 4 in Figure 5-13). If you are already logged in, continue with Step 2.
Step 2 Install the OC-N cards that will serve as the BLSR trunk (span) cards if they are not already installed. See the "NTP-A16 Install Optical Cards and Connectors" procedure.
Figure 5-13 shows two BLSRs shared by one ONS 15454. Ring 1 runs on Nodes 1, 2, 3, and 4. Ring 2 runs on Nodes 4, 5, 6, and 7 and represents the subtending ring added by this procedure. Two BLSR rings, Ring 1 and Ring 2, are provisioned on Node 4. Ring 1 uses cards in Slots 5 and 12, and Ring 2 uses cards in Slots 6 and 13.
Figure 5-13 BLSR Subtended from a BLSR
Step 3 Attach fibers from the trunk cards in the subtending node to the BLSR trunk cards on its two neighboring BLSR nodes. In Figure 5-13, Node 4/Slot 6 connects to Node 7/Slot 13, and Node 4/Slot 13 connects to Node 5/Slot 6. See the "DLP-A44 Install Fiber-Optic Cables for BLSR Configurations" task.
Step 4 Create the DCCs on the first OC-N card that will carry the BLSR. See the "DLP-A377 Provision Section DCC Terminations" task. Alternatively, if additional bandwidth is needed for CTC management, complete the"DLP-A378 Provision Line DCC Terminations" task.
Step 5 Repeat Step 4 for the second OC-N trunk card that will carry the BLSR.
Step 6 Complete the "NTP-A40 Provision BLSR Nodes" procedure for each node that will be in the BLSR. If you have already provisioned the BLSR, perform this procedure for the subtending node only.
Step 7 If the subtending BLSR is not already created, complete the "NTP-A126 Create a BLSR" procedure to provision the new BLSR. The subtending BLSR must have a ring name that differs from the ring name of the first BLSR.
Note The subtending node can have one Node ID that is used in both BLSRs, or a different Node ID for each BLSR. For example, the same node can be Node 4 in BLSR 1 and Node 2 in BLSR 2.
Step 8 From the View menu, choose Go to Network View to see the subtending ring.
Figure 5-14 shows an example of two subtending BLSRs.
