Turn Up Network


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).


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.

Note To provision Ethernet ports, see the "DLP-A220 Provision E-Series Ethernet Ports" task on page 8-66 or the "DLP-A222 Provision G-Series Ethernet Ports" task on page 8-86.



Step 1 In node view 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 2 Click the Provisioning > Line tabs.

Step 3 In the State area, 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, but alarm reporting is suppressed and loopbacks are allowed. Raised fault conditions, whether or not their alarms are reported, 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. After the soak period passes, the port changes to IS. 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 4 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 port will stay in OOS-AINS after a signal is continuously received. When the soak period elapses, the port changes to IS.

Step 5 Click Apply.

Step 6 As needed, repeat this task for each port.

Step 7 Return to your originating procedure (NTP).

Step 4 In the BLSR Creation dialog box, set the BLSR properties:

Ring Type—Choose the BLSR ring type, either two-fiber or four-fiber.

Speed—Choose the BLSR ring speed: OC-12 (two-fiber BLSR only), OC-48, or OC-192. The speed must match the OC-N speed of the BLSR trunk (span) cards.


Note If you are creating an OC-12 BLSR and will eventually upgrade it to OC-48 or OC-192, use the single-port OC-12 cards (OC12 IR/STM4 SH 1310, OC12 IR/STM4 SH 1310, or OC12 IR/STM4 SH 1310). You cannot upgrade a BLSR on a four-port OC-12 (OC12/STM4-4) because OC-48 and OC-192 cards are single-port.


Ring Name—Assign a ring name. The name can be from 1 to 6 characters in length. Any alphanumeric string is permissible, and upper and lower case letters can be combined. Do not use the character string "All" in either upper or lower case letters, this is a TL1 keyword and will be rejected. Do not choose a name that is already assigned to another BLSR.

Reversion time—Set the amount of time that will pass before the traffic reverts to the original working path following a ring switch. The default is 5 minutes. Ring reversions can be set to Never.

For four-fiber BLSRs only, complete the following:

Span Reversion—Set the amount of time that will pass before the traffic reverts to the original working path following a span switch. The default is 5 minutes. Span reversions can be set to Never.

Step 5 Click Next. If the network graphic appears, go to Step 6.

If CTC determines that a BLSR cannot be created, for example, not enough optical cards are installed or it finds circuits with path protection selectors, a "Cannot Create BLSR" message appears. If this occurs, complete the following steps:

a. Click OK.

b. In the Create BLSR window, click Excluded Nodes. Review the information explaining why the BLSR could not be created, then click OK.

c. Depending on the problem, click Back to start over or click Cancel to cancel the operation.

Step 6 In the network graphic, double-click a BLSR span line. If the span line is DCC connected to other BLSR cards that constitute a complete ring, the lines turn blue and the Finish button appears. If the lines do not form a complete ring, double-click span lines until a complete ring is formed. When the ring is DCC connected, go to Step 7 if you are completing a four-fiber BLSR or go to Step 8 if you are completing a two-fiber BLSR.

Step 7 For four-fiber BLSRs, click Next. For two-fiber BLSRs go to go to Step 8. In the Protect Port Selection section, choose the protect ports from the West Protect and East Protect columns. Go to the next step.

Step 8 Click Finish. If the BLSR window appears with the BLSR you created, go to Step 9. If a "Cannot Create BLSR" or "Error While Creating BLSR" message appears:

a. Click OK.

b. In the Create BLSR window, click Excluded Nodes. Review the information explaining why the BLSR could not be created, then click OK.

c. Depending on the problem, click Back to start over or click Cancel to cancel the operation.

d. Complete the "A40 Provision BLSR Nodes" procedure, making sure all steps are completed accurately, then start this procedure again.

Step 1 In node view, click the Provisioning > Ring tabs.

Step 2 Click Create.

Step 3 In the Suggestion dialog box, click OK.

Step 4 In the Create BLSR dialog box, set the BLSR properties:

Ring Type—Choose the BLSR ring type, either two-fiber or four-fiber.

Ring Name—Assign a ring name. You must use the same ring name for each node in the BLSR. Any alphanumeric character string is permissible, and upper and lower case letters can be combined. Do not use the character string "All" in either upper or lower case letters, this is a TL1 keyword and will be rejected. Do not choose a name that is already assigned to another BLSR.

Node ID—Choose a Node ID from the pull-down menu (0 through 31). The Node ID identifies the node to the BLSR. Nodes in the same BLSR must have unique Node IDs.

Reversion time—Set the amount of time that will pass before the traffic reverts to the original working path. The default is 5 minutes. All nodes in a BLSR must have the same reversion time setting.

West Line—Assign the west BLSR port for the node from the pull-down menu.


Note The east and west ports must match the fiber connections and DCC terminations set up in the "A40 Provision BLSR Nodes" procedure.


East Line—Assign the east BLSR port for the node from the pull-down menu.

For four-fiber BLSRs, complete the following:

Span Reversion—Set the amount of time that will pass before the traffic reverts to the original working path following a span reversion. The default is 5 minutes. Span reversions can be set to Never. If you set a reversion time, the times must be the same for both ends of the span. That is, if Node A's west fiber is connected to Node B's east port, the Node A west span reversion time must be the same as the Node B east span reversion time. To avoid reversion time mismatches, Cisco recommends that you use the same span reversion time throughout the ring.

West Protect—Assign the west BLSR port that will connect to the west protect fiber from the pull-down menu.

East Protect—Assign the east BLSR port that will connect to the east protect fiber from the pull-down menu.

Step 5 Click OK.


Note Some or all of the following alarms will appear until all the BLSR nodes are provisioned: E-W MISMATCH, RING MISMATCH, APSCIMP, APSDFLTK, BLSROSYNC. The alarms will clear after you configure all the nodes in the BLSR.

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 6-8 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.

Figure 6-8 ONS 15454 Open-Ended Path Protection Fiber Connection Example

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 1-48 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 3-24. If you are already logged in, continue with Step 4.

Step 4 Complete the "DLP-A354 Provision SONET DCC Terminations" task or "DLP-A355 Provision SONET LDCC Terminations" task for the ONS 15454 cards/ports that are connected to another ONS 15454. Do not create DCC or LDCC terminations for the card/port that connects to the third-party equipment. For example in Figure 6-8, DCC terminations are created at the following cards/ports:

Nodes 1 and 6: Slot 5 and Slot 12

Node 2 and 5: Slot 12

Node 3 and 4: Slot 5


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


Step 5 Repeat Steps 3 through 4 for each node in the path protection.

Step 6 Following the documentation provided by the third-party vendor, provision the optical loop leading from the ONS 15454 connection at one end to the ONS 15454 connection at the other end. In other words, you will create an open-ended path protection using procedures for the third-party equipment.

Step 7 Complete the "A225 Open-Ended Path Protection Acceptance Test" procedure.

Stop. You have completed this procedure.


NTP-A225 Open-Ended Path Protection Acceptance Test

b. Complete the "DLP-A516 Export CTC Data" task to export the conditions information.

Step 5 On the network map, double-click the node that you logged into in Step 1.

Step 6 Create a test circuit from that node to the OC-N trunk (span) cards on the nodes that connect to the third-party network. For example, in Figure 6-8, a circuit is created from Node 1 to the Slot 5 OC-N card at Node 2, and a secondary circuit destination is created on the Slot 12 OC-N card at Node 3. For circuit creation procedures, complete one of the following:

For DS-1 circuits, complete the "NTP-A181 Create an Automatically Routed DS-1 Circuit" procedure on page 8-6. When you set the circuit state, choose IS and check the Apply to drop ports check box.

For DS-3 circuits, complete the "NTP-A184 Create an Automatically Routed DS-3 Circuit" procedure on page 8-22. When you set the circuit state, choose IS and check the Apply to drop ports check box.

For OC-N circuits, complete the "NTP-A188 Create an Automatically Routed OC-N Circuit" procedure on page 8-42. 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 15454 connection ports to the second set of ONS 15454 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 6-8, 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 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, then choose the DS-1 to test on the muxed DS-3. For information about configuring your test set, consult your test set user guide.

OC-N—If you are testing an OC-N circuit, set the test set for the applicable circuit size. 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 1 through 8 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-A356 TCC2 Active/Standby Switch Test" task.

Step 16 Complete the "DLP-A255 Cross-Connect Card Side Switch Test" task.
