Convert Network Configurations
This chapter explains how to convert from one SONET topology to another in a Cisco ONS 15454 network. For initial network turn up, see "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 procedure is service affecting.
Note Optical transmit and receive levels should be in their acceptable range as shown in Table 2-5.
Step 1 Complete the "DLP-A60 Log into CTC" task at one of the nodes that you want to convert from a point-to-point or ADM to a BLSR. If you are already logged in, continue with Step 2.
Step 2 According to local site practice, complete the "A108 Back Up the Database" procedure for each node in the configuration.
Step 3 Complete the "DLP-A298 Check the Network for Alarms and Conditions" task.
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 STS 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 OC-48, no more than 24 STSs can be provisioned on the span. If the span is an OC-192, no more than 96 STSs can be provisioned on the span. If the span is an OC-12, no more than 6 STSs can be provisioned on the span.
If the first half of the capacity is exceeded, this procedure cannot be completed. Bandwidth must be 50 percent unassigned to convert to a BLSR. Refer to local procedures for relocating circuits if these requirements are not met.
Step 7 Repeat Steps 4 through 6 for each node in the point-to-point or linear ADM that you will convert to a BLSR. When all nodes comply with Step 6, proceed to the next step.
Step 8 For every node in the point-to-point or linear ADM network that you want to convert to a BLSR, complete the following tasks:
a. Complete the "DLP-A189 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-A155 Delete a Protection Group" task at each node that supports the point-to-point or linear ADM span.
c. Complete the "DLP-A214 Change the Service State for a Port" task 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 (as shown in Figure 15-1) can be removed.
Figure 15-1 Linear ADM to BLSR 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 (as shown in Figure 15-1) can be rerouted to connect Node 1/Slot 5 to Node 3/Slot 13.
Note If you need to remove any OC-N cards from the shelf do so now. In this example, cards in Node 2/Slots 5 and 13 can be removed. See the "A116 Remove and Replace a Card" procedure.
Step 11 From the network view, click the Circuits tabs and complete the "DLP-A516 Export CTC Data" task to save the circuit data to a file on your hard drive.
Step 12 Complete the "DLP-A354 Provision SONET DCC Terminations" task 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 an STS that is now part of the protection bandwidth (STSs 7 to 12 for an OC-12 BLSR, STSs 25 to 48 for an OC-48 BLSR, and STSs 97 to 192 for an OC-192 BLSR), delete and recreate each circuit:
a. Complete the "DLP-A333 Delete Circuits and DWDM Optical Channel Network Connections" task for one circuit.
b. Create the circuit on STSs 1 to 6 for an OC-12 BLSR, STSs 1 to 24 for an OC-48 BLSR, or STSs 1 to 96 for an OC-192 BLSR on the fiber that served as the protect fiber in the linear ADM. See the "A189 Create a Manually Routed OC-N Circuit" procedure for instructions.
c. Repeat Steps a and b for each circuit residing on a BLSR protect STS.

Note A path protection is the default configuration if the cards installed are installed and the DCCs are configured.
Stop. You have completed this procedure.
NTP-A210 Convert a Path Protectionto a Two-Fiber BLSR
This procedure is service affecting. All circuits on the ring are deleted and reprovisioned.
Read through this procedure completely before beginning the conversion.
Note Prior to beginning this procedure, you should have a unique ring name to identify the new BLSR and a unique node ID number for each node on the ring.
Note Prior to beginning this procedure, optical transmit and receive levels should be in their acceptable range as shown in Table 2-5.
Step 1 Complete the "DLP-A60 Log into CTC" task at a node on the path protection. If you are already logged in, continue with Step 2.
Step 2 Complete the "DLP-A298 Check the Network for Alarms and Conditions" task.
Step 3 On the network map, right-click a span adjacent to the node you are logged into. A shortcut menu appears.
Step 4 From the shortcut menu, click Circuits. The Circuits on Span window appears.
Step 5 Verify that the total number of active STS 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 OC-48, no more than 24 STSs can be provisioned on the span. If the span is an OC-192, no more than 96 STSs can be provisioned on the span. If the span is an OC-12, no more than 6 STSs can be provisioned on the span.
If the first half of the capacity is exceeded, this procedure cannot be completed. Bandwidth must be 50 percent unassigned to convert to BLSR. Refer to local procedures for relocating circuits if these requirements are not met.
Step 6 Repeat Steps 1 through 5 for each node in the path protection that you will convert to a BLSR. When all nodes comply with Step 5, continue with the next step.
Step 7 Save all circuit information:
a. In network view, click the Circuits tab.
b. Record the circuit information using one of the following options:
•From the File menu, click Print to print the circuits table. See the "DLP-A515 Print CTC Data" task for more information.
•From the File menu, click Export and choose the data format: HTML, CSV (comma separated values), or TSV (tab separated values). Click OK and save the file in a temporary directory. See the "DLP-A516 Export CTC Data" task for more information.
Step 8 Delete the circuits:
Note This method uses the network view. To delete circuits one at a time from each node, see the "A278 Modify and Delete Overhead Circuits" procedure.
a. In network view, click the Circuits tab. All circuits on the ring appear.
b. With the Ctrl key pressed, click each circuit. Each line turns dark blue as it is selected.
c. After all circuits have been selected, click Delete. Allow several minutes for processing; the actual length of time depends on the number of circuits in the network.
Step 9 Complete the "A126 Create a BLSR" procedure to create the BLSR.
Step 10 To recreate the circuits, see "Create Circuits and VT Tunnels" and choose the applicable procedure for the circuit type you want to enter.
Note To add additional nodes to a BLSR, see the "A212 Add a BLSR Node" procedure.
Stop. You have completed this procedure.
NTP-A211 Convert a Two-Fiber BLSR to a Four-Fiber BLSR
Note Two-fiber OC-48 or OC-192 BLSRs can be converted to four-fiber BLSRs. To convert, install two additional OC-48 or OC-192 cards at each two-fiber BLSR node, then log into CTC and convert the BLSR from two-fiber to four-fiber. The fibers that were divided into working and protect bandwidths for the two-fiber BLSR are now fully allocated for working BLSR traffic. A span upgrade can be performed prior to the two-fiber to four-fiber BLSR conversion.
Note BLSR protection channel access (PCA) circuits, if present, will remain in their existing STSs. Therefore, they will be located on the working path of the four-fiber BLSR and will have full BLSR protection. To route PCA circuits on protection channels in the four-fiber BLSR, delete and recreate the circuits after the upgrade. For example, if you upgrade a two-fiber OC-48 BLSR to four-fiber, PCA circuits on the protection STSs (STSs 25 to 48) in the two-fiber BLSR will remain in their existing STSs, which are working STSs in the four-fiber BLSR. Deleting and recreating the OC-48 PCA circuits moves the circuits to STSs 1 to 24 in the protect bandwidth of the four-fiber BLSR. To delete circuits, see the "A278 Modify and Delete Overhead Circuits" procedure. To create circuits, see "Create Circuits and VT Tunnels."
Note Prior to beginning this procedure, optical transmit and receive levels should be in their acceptable range as shown in Table 2-5.
Step 1 Complete the "DLP-A60 Log into CTC" task at one of the two-fiber nodes that you want to convert.
Step 2 Complete the "DLP-A298 Check the Network for Alarms and Conditions" task.
Step 3 Complete the "A16 Install the OC-N Cards" procedure to install two OC-48 or OC-192 cards at each BLSR node. You must install the same OC-N card rate as the two-fiber BLSR.
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 "A247 Install Fiber-Optic Cables on OC-N Cards" procedure.
Step 5 Complete the "DLP-A214 Change the Service State for a Port" task to enable (put in service) the ports for each new OC-N card.
Step 6 Test the new fiber connections using procedures standard for your site.
Step 7 Convert the BLSR:
a. Display the network view and click the Provisioning > BLSR tabs.
b. Choose the two-fiber BLSR you want to convert then click the Upgrade to 4 Fiber button.
c. In the Upgrade BLSR 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 BLSR port that will connect to the west protect fiber from the drop-down menu.
•East Protect—Select the east BLSR 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-A227 Disable Alarm Filtering" task 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 9 Complete the "A176 Four-Fiber BLSR Acceptance Test" procedure.
Stop. You have completed this procedure.
NTP-A159 Modify a BLSR
Step 1 Complete the "DLP-A60 Log into CTC" task at a node in the BLSR you want to modify. If you are already logged in, continue with Step 2.
Step 2 Complete the "DLP-A298 Check the Network for Alarms and Conditions" task.
Note Some or all of the following alarms appear during BLSR setup: E-W MISMATCH, RING MISMATCH, APSCIMP, APSDFLTK, and BLSROSYNC. The alarms clear after you configure all the nodes in the BLSR. For definitions of these alarms, see the Cisco ONS 15454 Troubleshooting Guide.
Step 3 To change the BLSR ring name or the ring or span reversion times, complete the following steps. If you want to change a node ID, continue with Step 4.
a. In network view, click the Provisioning > BLSR tabs.
b. Click the BLSR you want to modify and click Edit.
c. In the BLSR window, change any of the following:
•Ring Name—Assign a ring name. The name can be from 1 to 6 characters in length. The alphanumeric character strings that can be used are 0 to 9 and A to Z. You can combine numbers and letters and use upper or lower case letters. Do not use the character string "All" in either upper or lower case letters because it is a TL1 keyword. Do not choose a name that is already assigned to another BLSR.
•Reversion time—If needed, change the amount of time that will pass before the traffic reverts to the original working path after a ring switch.
•Span Reversion—(Four-fiber BLSRs only) If needed, change the amount of time that will pass before the traffic reverts to the original working path after a span switch.
