Note Optical transmit and receive levels should be in their acceptable range as shown in Table 2-5 on page 2-31.



Note In a point-to-point configuration, two STM-N cards are connected to two STM-N cards on a second node. The working STM-N ports have data communications channel (DCC) terminations, and the STM-N cards are in a 1+1 protection group.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at one of the two point-to-point nodes. If you are already logged in, continue with Step 2.

Step 2 Complete the "DLP-D298 Check the Network for Alarms and Conditions" task.

Step 3 Log into the node that will be added to the point-to-point configuration (the new node).

Step 4 Complete the "NTP-D24 Verify Card Installation" procedure on page 4-2 to ensure that the new node has two STM-N cards with the same rate as the point-to-point nodes.

Step 5 Complete the "NTP-D35 Verify Node Turn Up" procedure on page 6-2 for the new node.

Step 6 Physically connect the fibers between the point-to-point node and the new node. The fiber connections should be connected working card to working card and protect card to protect card.

Step 7 On the new node, create a 1+1 protection group for the STM-N cards that will connect to the point-to-point node. See the "DLP-D73 Create a 1+1 Protection Group" task on page 4-30.

Step 8 Complete the "DLP-D464 Provision SDH DCC Terminations" task on page 6-4 for the working STM-N cards in the new node that will connect to the linear ADM network. Make sure to set the Port State in the Create SDCC Termination dialog box to IS.


Note DCC failure alarms appear until you create DCC terminations in the point-to-point node.


Step 9 Display the point-to-point node that will connect to the new node in CTC node view.

Step 10 Complete the "NTP-D24 Verify Card Installation" procedure on page 4-2 to ensure that the point-to-point node has STM-N cards installed that can connect to the new node.

Step 11 Create a 1+1 protection group for the STM-N cards in the point-to-point node that will connect to the new node. See the "DLP-D73 Create a 1+1 Protection Group" task on page 4-30 for instructions.

Step 12 Create DCC terminations on the working STM-N card in the point-to-point node that will connect to the new node. See the "DLP-D464 Provision SDH DCC Terminations" task on page 6-4. In the Create SDCC Termination dialog box, set the port state to IS.

Step 13 From the view menu choose Go to Node View to display the new node in node view.

Step 14 Complete the "NTP-D28 Set Up Timing" procedure on page 4-22 for the new node. If the new node is using line timing, set the working STM-N card as the timing source.

Step 15 From the view menu choose Go to Network View to display the network view to verify that the newly created linear ADM configuration is correct. One green span lines should appear between each linear node.

Step 16 Click the Alarms tab.

Note Optical transmit and receive levels should be in their acceptable range as shown in Table 2-5 on page 2-31.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at one of the nodes that you want to convert from a point-to-point or ADM to an MS-SPRing. If you are already logged in, continue with Step 2.

Step 2 According to local site practice, complete the "NTP-D108 Back Up the Database" procedure on page 17-8 for each node in the configuration.

Step 3 Check for alarms and conditions. See the "DLP-D298 Check the Network for Alarms and Conditions" task for instructions.

Step 4 On the network map right-click a span adjacent to the node you are logged into. A shortcut menu appears.

Step 5 From the shortcut menu, click Circuits. The Circuits on Span window appears.

Step 6 Verify that the total number of active VC4 circuits does not exceed 50 percent of the span bandwidth. In the Circuits column, there is a block titled "Unused." This number should exceed 50 percent of the span bandwidth.


Note If the span is an STM-16, no more than 8 VC4s can be provisioned on the span. If the span is an STM-64, no more than 32 VC4s can be provisioned on the span. If the span is an STM-4, no more than 2 VC4s can be provisioned on the span.



Caution If the first half of the capacity is exceeded, this procedure cannot be completed. Bandwidth must be 50 percent unassigned to convert to an MS-SPRing. Refer to local procedures for relocating circuits if these requirements are not met.

Step 7 Repeat Step 4 through Step 6 for each node in the point-to-point or linear ADM that you will convert to MS-SPRing. When all nodes comply with Step 6, continue with the next step.

Step 8 For every node in the point-to-point or linear ADM network that you want to convert to an MS-SPRing, complete the following tasks:

a. Complete the "DLP-D189 Verify that a 1+1 Working Slot is Active" task for every 1+1 protection group that supports a span in the point-to-point or linear ADM network.

b. Complete the "DLP-D155 Delete a Protection Group" task on page 12-20 at each node that supports the point-to-point or linear ADM span.

c. Complete the "DLP-D214 Change the Service State for a Port" task on page 6-6 to put the protect ports out of service at each node that supports the point-to-point or linear ADM span.

Step 9 (Linear ADM only) Physically remove the protect fibers from all nodes in the linear ADM; for example, the fiber running from Node 2/Slot 13 to Node 3/Slot 13 can be removed (Figure 15-1).

Figure 15-1 Linear ADM to MS-SPRing Conversion

Step 10 Create the ring by connecting the protect fiber from one end node to the protect port on the other end node. For example, the fiber between Node 1/Slot 5 and Node 2/Slot 5 can be rerouted to connect Node 1/Slot 5 to Node 3/Slot 13 (Figure 15-1).


Note If you need to remove any STM-N cards from the shelf do so now. In this example, cards in Node 2/Slots 5 and 13 can be removed. See the "NTP-D227 Remove and Replace a Card" procedure on page 2-58.


Step 11 From the network view, click the Circuits tabs and complete the "DLP-D423 Export CTC Data" task on page 9-4 to save the circuit data to a file on your hard drive.

Step 12 Complete the "DLP-D464 Provision SDH DCC Terminations" task on page 6-4 at the end nodes; provision the slot in each node that is not already in the SDCC Terminations list (in the Figure 15-1 example, Port 1 of Node 1/Slot 5 and Port 1 of Node 3/Slot 13).

Step 13 For circuits provisioned on a VC4 that is now part of the protection bandwidth (VC4s 3 to 4 for an STM-4 MS-SPRing, VC4s 9 to 16 for an STM-16 MS-SPRing, and VC4s 33 to 64 for an STM-64), delete and recreate each circuit:

a. Complete the "DLP-D27 Delete Circuits and DWDM Optical Channel Network Connections" task on page 11-17 for one circuit.

b. Create the circuit on VC4s 1 to 2 for an STM-4 MS-SPRing, 1 to 8 for an STM-16 MS-SPRing, or 1 to 32 for an STM-64 MS-SPRing on the fiber that served as the protect fiber in the linear ADM. See the "NTP-D189 Create a Manually Routed High-Order Circuit" procedure on page 8-51 for instructions.

c. Repeat Steps a and b for each circuit residing on an MS-SPRing protect VC4.

Step 14 Complete the "NTP-D41 Create the MS-SPRing" procedure on page 6-18 to put the nodes into an MS-SPRing.

Stop. You have completed this procedure.

Note Two-fiber STM-16 or STM-64 MS-SPRings can be converted to four-fiber MS-SPRings. To convert, you install two additional STM-16 or STM-64 cards at each two-fiber MS-SPRing node, then log into CTC and convert the MS-SPRing from two-fiber to four-fiber. The fibers that were divided into working and protect bandwidths for the two-fiber MS-SPRing are now fully allocated for working MS-SPRing traffic. A span upgrade can be performed prior to the two-fiber to four-fiber MS-SPRing conversion.



Note MS-SPRing protection channel access (PCA) circuits, if present, will remain in their existing VC4s. Therefore, they will be located on the working path of the four-fiber MS-SPRing and will have full MS-SPRing protection. To route PCA circuits on protection channels in the four-fiber MS-SPRing, delete and recreate the circuits after the upgrade. For example, if you upgrade a two-fiber STM-16 MS-SPRing to four-fiber, PCA circuits on the protection VC4s (VCs 8 to 16) in the two-fiber MS-SPRing will remain in their existing VC4s, which are working VC4s in the four-fiber MS-SPRing. Deleting and recreating the STM-16 PCA circuits moves the circuits to VC4s 1 to 7 in the protect bandwidth of the four-fiber MS-SPRing. To delete circuits, see the "NTP-D288 Modify and Delete Overhead Circuits" procedure on page 11-18. To create circuits, see Chapter 8, "Create Circuits and Low-Order Tunnels."



Note Before beginning this procedure, optical transmit and receive levels should be in their acceptable range as shown in Table 2-5 on page 2-31.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at one of the two-fiber nodes that you want to convert.

Step 2 Complete the "DLP-D298 Check the Network for Alarms and Conditions" task.

Step 3 Complete the "NTP-D16 Install the STM-N Cards" procedure on page 2-12 to install two STM-16 or STM-64 cards at each MS-SPRing node. You must install the same STM-N card rate as the two-fiber MS-SPRing.

Step 4 Connect the fiber to the new cards. Use the same east-west connection scheme that was used to create the two-fiber connections. See the "NTP-D19 Install Fiber-Optic Cables on STM-N Cards" procedure on page 2-30.

Step 5 Complete the "DLP-D214 Change the Service State for a Port" task on page 6-6 to put the ports in service on each new STM-N card.

Step 6 Test the new fiber connections using procedures standard for your site.

Step 7 Convert the MS-SPRing:

a. From the View menu, choose Go to Network View. Click the Provisioning > MS-SPRing tabs.

b. Choose the two-fiber MS-SPRing you want to convert, then click the Upgrade to 4 Fiber button.

c. In the Upgrade MS-SPRing dialog box, set the amount of time that will pass before the traffic reverts to the original working path after the condition that caused the switch has been resolved. The default is 5 minutes.

d. Click Next.

e. Assign the east and west protection ports:

West Protect—Select the west MS-SPRing port that will connect to the west protect fiber from the drop-down menu.

East Protect—Select the east MS-SPRing port that will connect to the east protect fiber from the drop-down menu.

f. Click Finish.

Step 8 Click the Alarms tab.

a. Verify that the alarm filter is not on. See the "DLP-D227 Disable Alarm Filtering" task on page 9-32 as necessary.

b. Verify that no unexplained alarms appear on the network. If alarms appear, investigate and resolve them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide for procedures.

Step 3 If you have timing set up on the OSCM card, delete the timing source:

a. In node view, click the Provisioning > Timing tabs.

b. Scroll down to the Reference Lists pane.

c. In the NE Reference column, select Internal Clock from the drop-down menu for all entries where the selected Clock Source is the OSCM that you are removing.

d. Click Apply.

Step 4 If you have overhead circuits on the node, complete the "DLP-D31 Delete Overhead Circuits" task on page 11-20.

Step 5 Delete the DWDM ring ID:

a. In node view, click the Provisioning > DCC/GCC/OSC > OSC tabs.

b. Select the DWDM Ring ID you want to delete and click Delete.

c. In the Delete DWDM Ring ID confirmation box, click Yes. Confirm that the changes appear.

Step 6 If you have OSC terminations, complete the "DLP-D352 Delete a DWDM OSC Termination" procedure on page 12-23.

Step 7 Delete the OSCM card WDM-ANS connections:

a. In node view, click the Provisioning > WDM-ANS > Connections tabs.

b. Select the connection to be deleted.

c. Click Delete.

d. From the Delete Optical Link dialog box, click Yes.

Step 8 Delete the card from CTC:

a. In node view, right-click the OSCM card.

b. Select Delete Card from the menu.

The card name disappears and the slot turns gray.

Step 9 Remove cables from the OSCM OSC ports.

Step 10 Physically replace the deleted OSCM card on the ONS 15454 with an OSC-CSM card:


Note The OSCM card and OSC-CSM card do not have the same slot requirements.


a. Open the OSCM card ejectors.

b. Slide the card out of the Slots 8 or 10.

c. Open the ejectors on the OSC-CSM card.

d. Slide the OSC-CSM card into the slot along the guide rails. Use Slots 1 to 6 or 12 to 17 according to your site plan.

e. Close the ejectors.


Note On the OSC-CSM card the fail LED above the ACT/STBY LED becomes red, blinks for several seconds, and turns off. The ACT/STBY LED turns green and remains illuminated. In node view, the OSC-CSM appears green.


Step 11 If an OSCM card was removed from Slot 8 and an OSC-CSM card was installed in Slots 12 through 17, modify the OSC-CSM line direction from east-to-west to west-to-east.


Note The MetroPlanner configuration file will label the OSC-CSM card as west even if it is installed in the east-side of the node.


a. To modify OSC-CSM card line direction, double-click the OSC-CSM card from node view.

b. Click the Provisioning > Optical Line > Parameter tabs.

c. In the port number 2 line, click the Line Direction drop-down menu and choose West to East.

d. Click Apply.

Step 12 If an OSCM card was removed from Slot 10 and an OSC-CSM card was installed in Slots 1 through 6, modify the OSC-CSM line direction from west-to-east to east-to-west.


Note The MetroPlanner configuration file will label the OSC-CSM card as east even if it is installed in the west-side of the node.


a. To modify OSC-CSM card line direction, double-click the OSC-CSM card from node view.

b. Click the Provisioning > Optical Line > Parameter tabs.

c. In the port number 2 line, click the Line Direction drop-down menu and choose East to West.
