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 a Cisco ONS 15327 network, including terminal point-to-point networks, linear add-drop multiplexers (ADMs), path protection configurations, bidirectional line switched rings (BLSRs), and subtending rings.

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 4-10 shows an example. Node 1 is connected to ONS 15327 Nodes 2 and 3 through Slots 1 and Slot 3. Trunk cards at Nodes 2 and 3 are connected to the third-party vendor equipment.
Figure 4-10 ONS 15327 Open-Ended Path Protection Configurations Fiber Connection Example
Step 2 Verify that the third-party cards or units to which the ONS 15327 trunk cards are connected are the same OC-N rate as the ONS 15327 trunk cards. The third-party time slots must match the ONS 15327 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 1-48 available.
Step 3 Complete the "DLP-B60 Log into CTC" task on page 16-52 at the node you are turning up. If you are already logged in, continue with Step 4.
Step 4 Complete the "DLP-B253 Provision Section DCC Terminations" task on page 18-39 for the ONS 15327 cards/ports that are connected to another ONS 15327. (Alternatively, if additional bandwidth is needed for CTC management, complete the "DLP-B24 Provision Line DCC Terminations" task on page 16-21.) Do not create a DCC termination for the card/port that connects to the third-party equipment. For example in Figure 4-10, DCC terminations are created at the following cards/ports:
•Nodes 1 and 6: Slot 1 and Slot 3
•Node 2 and 5: Slot 3
•Node 3 and 4: Slot 1
Note If an ONS 15327 is not connected to a corporate LAN, DCC provisioning must be performed through a direct (craft) connection. Remote provisioning is possible only after all nodes in the network have DCC terminations provisioned to in-service OC-N ports.
Step 5 Repeat Steps 3 and 4 for each node in the path protection.
Step 6 As needed, complete the "DLP-B29 Provision a Proxy Tunnel" task on page 16-24.

For circuit creation procedures, complete one of the following:
•For DS-1 circuits, complete the "NTP-B181 Create an Automatically Routed DS-1 Circuit" procedure on page 5-6. When you set the circuit state, choose IS and check the Apply to drop ports check box.
•For DS-3 circuits, complete the "NTP-B184 Create an Automatically Routed DS-3 Circuit" procedure on page 5-17. When you set the circuit state, choose IS and check the Apply to drop ports check box.
Step 7 Create a circuit within the third-party network from ONS 15327 connection ports to the second set of ONS 15327 connection ports on both path protection spans. Refer to the third-party equipment documentation for circuit creation procedures.
Step 8 Repeat Step 6 to create a second circuit at the terminating node on the other side of the third-party network. In Figure 4-10, this is Node 6. However, this circuit will have two sources, one at Node 4/Slot 12, and one at Node 5/Slot 5. The destination will be a drop card on Node 6.
Step 9 Configure the test set for the test circuit type you created:
•DS-1—If you are testing an unmuxed DS-1, you must have a DSX-1 panel or a direct DS-1 interface into the ONS 15327. Set the test set for DS-1. For information about configuring your test set, consult your test set user guide.
•DS-3—If you are testing a clear channel DS-3, you must have a DSX-3 panel or a direct DS-3 interface into the ONS 15327. Set the test set for clear channel DS-3. For information about configuring your test set, consult your test set user guide.
Step 10 Verify the integrity of all patch cables that will be used in this test by connecting one end to the test set transmit (Tx) connector and the other end to the test set receive (Rx) connector. If the test set does not run error-free, check the cable for damage and check the test set to make sure it is set up correctly before continuing.
Step 11 Create a physical loopback at the circuit destination card:
a. Attach one end of a patch cable to the destination port's transmit (Tx) connector.
b. Attach the other end to the port's receive (Rx) connector.
Step 12 At the circuit source card:
a. Connect the transmit (Tx) connector of the test set to the circuit receive (Rx) connector.
b. Connect the test set receive (Rx) connector to the circuit transmit (Tx) connector.
Step 13 Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps 8 through 12 to make sure the test set and cabling are configured correctly.
Step 14 Inject BIT errors from the test set. To verify that you have a complete end-to-end circuit, verify that the errors appear at the test set.
Step 15 Complete the "DLP-B254 XTC Active/Standby Switch Test" task on page 18-40.
Step 16 From the View menu, choose Go to Network View.
Step 17 Click one of the two spans leaving the circuit source node.

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-B102 Add a BLSR Node" procedure on page 13-2.
Step 1 Complete the "DLP-B60 Log into CTC" task on page 16-52 at the node that will subtend the BLSR. 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-B218 Install the Optical and Ethernet Cards" procedure on page 1-11.
Figure 4-12 shows two BLSRs shared by one ONS 15327. 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 1 and 2, and Ring 2 uses cards in Slots 3 and 4.
Note Although different node IDs are used for the two BLSRs shown in Figure 4-12, nodes in different BLSRs can use the same node ID.

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 4-12, Node 4/Slot 3 connects to Node 7/Slot 4, and Node 4/Slot 4 connects to Node 5/Slot 3.
Step 4 Create the DCCs on the first OC-N card that will carry the BLSR. See the "DLP-B253 Provision Section DCC Terminations" task on page 18-39 or the "DLP-B24 Provision Line DCC Terminations" task on page 16-21 for instructions.
Step 5 Repeat Step 4 for the second OC-N trunk card that will carry the BLSR.
Step 6 As needed, complete the "DLP-B29 Provision a Proxy Tunnel" task on page 16-24.
Step 7 As needed, complete the "DLP-B31 Provision a Firewall Tunnel" task on page 16-26.
Step 8 As needed, complete the "DLP-B22 Create a Provisionable Patchcord" task on page 16-19.
Step 9 Complete the "B40 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 10 If the subtending BLSR is not already created, complete the "B126 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. 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 11 From the View menu choose Go to Network View to see the subtending ring.
Step 12 Complete the "B175 BLSR Acceptance Test" procedure.
