Turn Up 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 15454s network, including point-to-point networks, linear add drop multiplexers (ADMs), path protection configurations, and bidirectional line switched rings (BLSRs).

Step 1 Display the node (login) view.

Step 2 On the shelf graphic, double-click the card with the port(s) you want to put in or out of service. The card view appears.

Step 3 Click the Provisioning > Line tabs.

Step 4 Under State, choose one of the following:

IS—The port is in-service.

OOS—The port is out-of-service. Traffic is not passed on the port until the service state is changed to IS, OOS_MT, or OOS_AINS.

OOS_MT—The port is in a maintenance state. The maintenance state does not interrupt traffic flow, alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command. Use OOS_MT for testing or to suppress alarms temporarily. Change the state to IS, OOS, or OOS_AINS when testing is complete.

OOS_AINS—The port is in an auto-inservice state; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command.

Step 5 If you set State to OOS-AINS, set the soak period time in the AINS Soak field. This is the amount of time that the state will stay in OOS-AINS state after the signal is continuously received.

Step 6 Click Apply.

Figure 5-3 Four-Node, Four-Fiber BLSR Fiber Connection Example

Step 2 Log into an ONS 15454 that you want to configure in a BLSR. See the "DLP-A60 Log into CTC" task on page 3-23 for instructions. If you are already logged in, continue with Step 3.

Step 3 Complete the "DLP-A253 Provision SONET DCC Terminations" task. Provision the two ports/cards that will serve as the BLSR ports at the node. For four-fiber BLSRs, provision the DCC terminations on the OC-N cards that will carry the working traffic, but do not provision DCCs on the protect cards.


Note If an ONS 15454 is not connected to a corporate LAN, DCC provisioning must be performed through a direct (craft) connection to the node. Remote provisioning is possible only after all nodes in the network have DCC provisioned to in-service OC-N ports.


Step 4 For four-fiber BLSRs, complete the "DLP-A214 Change the Service State for a Port" task to put the protect OC-N cards/ports in service.

Step 5 If a BLSR span passes through third-party equipment that cannot transparently transport the K3 byte, complete the "DLP-A89 Remap the K3 Byte" task. This task is not necessary for most users.

Step 6 Repeat Steps 2 through 4 at each node that will be in the BLSR. Verify that the EOC (DCC Termination Failure) and LOS (Loss of Signal) are cleared after DCCs are provisioned on all nodes in the ring.

Step 7 Complete the "126 Create a BLSR" procedure.

For DS-3 circuits, complete the "NTP-A184 Create an Automatically Routed DS-3 Circuit" procedure on page 6-20. When you set the circuit state, choose IS and check the Apply to drop ports check box.

Step 11 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 15454. 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 15454. Set the test set for clear channel DS-3. For information about configuring your test set, consult your test set user guide.

DS3XM-6—If you are testing a DS-1 circuit on a DS3XM-6 card you must have a DSX-3 panel or a direct DS-3 interface to the ONS 15454. Set the test set for a muxed DS3. After you choose muxed DS-3, choose the DS-1 to test on the muxed DS-3. For information about configuring your test set, consult your test set user guide.

Step 12 Verify the integrity of all patch cables that will be used in this test by connecting one end of the cable to the test set transmit (Tx) connector and the other end of the cable 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 13 Create a physical loopback at the circuit destination card. To do so, attach one end of a patch cable to the destination port's transmit (Tx) connector; attach the other end to the port's receive (Rx) connector.

Step 14 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 15 Verify that the test set displays a clean signal. If a clean signal is not displayed, repeat Steps 8 through 14 to make sure the test set and cabling are configured correctly.

Step 16 Inject global BIT errors from the test set. Verify that the errors display at the test set, verifying a complete end-to-end circuit.

Step 17 This step will lockout both of the spans on the node where you perform this task. Complete the "DLP-A254 TCC+/TCC2 Active/Standby Switch Test" task.

Step 18 This step will lockout both of the spans on the node where you perform this task. Complete the "DLP-A255 Cross-Connect Card Side Switch Test" task.

Step 19 Complete the "DLP-A91 BLSR Switch Test" task to test the BLSR protection switching at Node 1.

Step 20 Complete the "DLP-A93 Four-Fiber BLSR Span Switching Test" task at Node 1.

Step 21 Set up and complete a BER test on the test circuit between Node 1 and 2. Use the existing configuration and follow your site requirements for length of time. Record the test results and configuration.

Step 22 Complete the "NTP-A152 Delete Circuits" procedure on page 9-16 for the test circuit.

Step 23 At Node 2, repeat Steps 7 through 23, creating a test circuit between Node 2 and the node connected to the east OC-N trunk card of Node 2 (Node 3). Work your way around the BLSR creating test circuits between every two consecutive nodes.

Step 24 After you test the entire ring, remove any loopbacks and test sets from the nodes.

Step 25 View Alarms and conditions on each node and record the results by exporting them to a file. See the "DLP-A139 Export CTC Data" task on page 7-4 for instructions.

Step 26 If a node fails any test, repeat the test while verifying correct setup and configuration. If the test fails again, refer to the next level of support.

After all tests are successfully completed and no alarms exist in the network, the network is ready for service application. Continue with Chapter 6, "Create Circuits and VT Tunnels."

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 5-9, Node 4/Slot 6 connects to Node 7/Slot 13, and Node 4/Slot 13 connects to Node 5/Slot 6.

Step 4 Create the DCCs on the first OC-N card that will carry the BLSR. See the "DLP-A253 Provision SONET DCC Terminations" task for instructions.

Step 5 Repeat Step 4 for the second OC-N trunk card that will carry the BLSR.

Step 6 Complete the "40 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 "126 Create a BLSR" procedure to provision the new BLSR. The subtending BLSR must have a ring ID that differs from the ring ID 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 8 Display the network view to see the subtending ring.

Figure 5-10 shows an example of two subtending BLSRs.

Step 9 Complete the "175 Two-Fiber BLSR Acceptance Test" procedure or the "176 Four-Fiber BLSR Acceptance Test" procedure depending on the type of BLSR.

Stop. You have completed this procedure.
