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 create Cisco ONS 15327 electrical circuits, VT tunnels, OC-N circuits, and Ethernet circuits. For additional information about ONS 15327 circuits, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15327 Reference Manual.

Table 5-1 defines ONS 15327 circuit creation terms and options.
Table 5-1 ONS 15327 Circuit Options
Circuit Option
|
Description
|
Source
|
The circuit source is where the circuit enters the ONS 15327 network.
|
Destination
|
The circuit destination is where the circuit exits an ONS 15327 network.
|
Automatic circuit routing
|
Cisco Transport Controller (CTC) routes the circuit automatically on the shortest available path based on routing parameters and bandwidth availability.
|
Manual circuit routing
|
Manual routing allows you to choose a specific path, not just the shortest path chosen by automatic routing. You can choose a specific synchronous transport signal (STS) or virtual tributary (VT) for each circuit segment and create circuits from work orders prepared by an operations support system (OSS) like the Telcordia Trunk Information Record Keeping System (TIRKS).
|
VT tunnel
|
VT tunnels allow VT1.5 circuits to pass through an ONS 15327 without utilizing cross-connect resources. VT circuits using VT tunnels use cross-connect capacity only at the source and destination nodes. One VT tunnel can carry 28 VT1.5 circuits.
|
VT aggregation point
|
VT aggregation points (VAPs) allow VT circuits to be aggregated into an STS for handoff to non-ONS 15327 networks or equipment, such as interoffice facilities (IOFs), switches, or digital access cross-connect systems. VAPs reduce VT matrix resource utilization at the node where the VT1.5s are aggregated onto the STS. This node is called the STS grooming end. The STS grooming end requires an OC-N, EC-1, or DS3XM-6 card. VT aggregation points can be created on bidirectional line switch ring (BLSR), 1+1, or unprotected nodes, but cannot be created on path protection nodes.
|
ONS 15327 circuits are either VT or STS circuits. Table 5-2 shows the circuit source and destination options for VT circuits.

Step 1 Complete the "DLP-B60 Log into CTC" task on page 16-52. If you are already logged in, continue with Step 2.
Step 2 From the View menu, choose Go to Network View. Wait for all the nodes that are part of the network to appear on the network map. (Large networks might take several minutes to display all the nodes.)
Note If this is the first time your computer has connected to this ONS 15327 network, the node icons will be stacked on the left side of the graphic area, possibly out of view. Use the scroll bar below the network map to display the icons. To separate the icons, press Ctrl and drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.
Step 3 Verify node accessibility. In the network view, all node icons must be either green, yellow, orange, or red.
If all network nodes do not appear after a few minutes, or if a node icon is gray with an IP address under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see Chapter 4, "Turn Up Network" to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15327 Troubleshooting Guide for troubleshooting procedures.
Step 4 Verify DCC connectivity. All nodes must be connected by green lines. If lines are missing or gray in color, do not continue. See Chapter 4, "Turn Up Network" and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing.
Step 5 Click the Alarms tab to view alarm descriptions. Investigate and resolve, if necessary, all critical (red node icon) or major (orange node icon) alarms. Refer to the Cisco ONS 15327 Troubleshooting Guide to resolve alarms before continuing.
Step 6 From the View menu, choose Go to Home View. Verify that the node is provisioned according to your site or engineering plan:
a. View the cards on the shelf map. Verify that the ONS 15327 cards appear in the specified slots.
b. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and Network Time Protocol/Simple Network Time Protocol (NTP/SNTP) server IP address (if used) are correctly provisioned. If needed, make corrections using the "NTP-B81 Change Node Management Information" procedure on page 9-2.
c. Click the Network tab. Verify that the IP address, Subnet mask, Default Router, and Gateway Settings are correctly provisioned. If not, make corrections using the "NTP-B201 Change CTC Network Access" procedure on page 9-2.
d. Click the Protection tab. Verify that protection groups are created as specified in your site plan. If the protection groups are not created, complete the "NTP-B170 Create 1+1 Protection Groups" procedure on page 3-8.
e. If the node is in a BLSR, click the BLSR tab. (If the node is not in a BLSR, continue with Step f.) Verify that the following items are provisioned as specified in your site plan:
•BLSR type (2-fiber)
•BLSR ring ID and node IDs
•Ring reversion time
•East and west card assignments
If you need to make corrections, see the "NTP-B40 Provision BLSR Nodes" procedure on page 4-10 for instructions.
f. Click the Security tab. Verify that the users and access levels are provisioned as specified. If not, see the "NTP-B30 Create Users and Assign Security" procedure on page 3-2 to correct the information.
g. If simple network management protocol (SNMP) is used, click the SNMP tab and verify the trap and destination information. If the information is not correct, see the "NTP-B87 Change SNMP Settings" procedure on page 9-6 to correct the information.
h. Click the Comm Channels tab. Verify that Section DCCs (SDCCs) and Line DCCs (LDCCs) were created to the applicable OC-N slots and ports. If SDCCs and LDCCs were not created for the appropriate OC-N slots and ports, see Chapter 4, "Turn Up Network" and complete the turn-up procedure appropriate for your network topology.
i. Click the Timing tab. Verify that timing is provisioned as specified. If not, use the "NTP-B85 Change Node Timing" procedure on page 9-4 to make the changes.
j. Click the Alarm Profiles tab. If you provisioned optional alarm profiles, verify that the alarms are provisioned as specified. If not, see the "NTP-B70 Create, Download, and Assign Alarm Severity Profiles" procedure on page 6-5 to change the information.
k. Verify that the network element defaults listed in the status area of the node view window is correct.
Step 7 Repeat Step 6 for each node in the network.
Step 8 As appropriate, complete the circuit creation procedure listed in the "Before You Begin" section.
Stop. You have completed this procedure.

Step 1 Complete the "DLP-B60 Log into CTC" task on page 16-52 at a node on the network where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-B314 Assign a Name to a Port" task on page 19-7. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VT. VT cross-connects will carry the DS-1 circuit across the ONS 15327 network.
•Number of Circuits—Enter the number of DS-1 circuits you want to create. The default is 1. If you are creating multiple circuits with the same slot and sequential port numbers, you can use autoranging to create the circuits automatically.
•Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Autoranging creates identical (same source and destination) sequential circuits automatically. Uncheck this check box if you do not want CTC to create sequential circuits automatically.
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 5-1):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—VT1.5 is the default. You cannot change it.
•Bidirectional—Leave checked for this circuit.
•Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Diagnostic—Leave unchecked.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–IS—Puts the circuit cross-connects in the In-Service and Normal (IS-NR) service state.
–OOS,DSBLD—Puts the circuit cross-connects in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD) service state. Traffic is not passed on the circuit.
–IS,AINS—Puts the circuit cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS) service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
–OOS,MT—Puts the circuit cross-connects in the Out-of-Service and Management, Maintenance (OOS-MA,MT) service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
Note If VT circuit source and destination ports are in an OOS-AU,AINS; OOS-MA,MT; or IS-NR service state, VT circuits in OOS-AU,AINS will change to IS-NR even if a physical signal is not present. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards and ports as source and destination choices.
Figure 5-1 Setting Circuit Attributes for a DS-1 Circuit
Step 8 If the circuit will be routed on a path protection, complete the "DLP-B218 Provision Path Protection Selectors During Circuit Creation" task on page 18-11. Otherwise, continue with the next step.
Step 9 Click Next.
Step 10 Complete the "DLP-B95 Provision a DS-1 Circuit Source and Destination" task on page 16-73.
Step 11 In the Circuit Routing Preferences area (Figure 5-2), check Route Automatically. Two options are available; choose either, both, or none based on your preferences:
•Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
•Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.
Figure 5-2 Setting Circuit Routing Preferences for a DS-1 Circuit
Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 15.
Caution Circuits routed on BLSR protection channels are not protected. They are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, check the Dual Ring Interconnect check box.
Step 15 If you selected Using Required Nodes/Spans in Step 11, complete the following substeps. If not, continue with Step 17.
a. Click Next.
b. In the Circuit Route Constraints area, click a node or span on the circuit map.
c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit will be routed. Click spans twice to change the circuit direction.
d. Repeat Step c for each node or span you wish to include or exclude.
e. Review the circuit route. To change the circuit routing order, choose a node from the Required Nodes/Lines or Excluded Notes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Step 16 Click Next. In the Create area of the VT Matrix Optimization panel, choose one of the following:
•Create VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15327s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Create VT aggregation point (VAP)—This option is available if the DS-1 circuit source or destination is on an EC-1, DS3XM-6, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs aggregate DS-1s onto an STS for handoff to non-ONS 15327 networks or equipment, such as an IOF, switch, or digital access and cross-connect system (DACS). It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15327 network, choose one of the following:
–STS grooming node is [source node], VT grooming node is [destination node]—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an OC-N card.
–STS grooming node is [destination node], VT grooming node is [source node]—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
Step 17 If you selected Review Route Before Creation in Step 11, complete the following substeps. If not, continue with Step 18.
a. Click Next.
b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "B182 Create a Manually Routed DS-1 Circuit" procedure.
Step 18 Click Finish. One of the following results occurs, depending on the circuit properties you chose in the Circuit Creation dialog box:
•If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If autoranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue autoranging. After completing the circuits, the Circuits window appears.
•If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears for you to create the remaining circuits. Repeat Steps 5 through 17 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 19 In the Circuits window, verify that the new circuits appear in the circuits list.
Step 20 Complete the "B135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

•Diagnostic—Leave unchecked.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–IS—Puts the circuit cross-connects in the IS-NR service state.
–OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
–IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
–OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
Note If VT circuit source and destination ports are in an OOS-AU,AINS; OOS-MA,MT; or IS-NR service state, VT circuits in OOS-AU,AINS will change to IS-NR even if a physical signal is not present. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards and ports as source and destination choices.
Step 8 If the circuit will be routed on a path protection, complete the "DLP-B218 Provision Path Protection Selectors During Circuit Creation" task on page 18-11. Otherwise, continue with the next step.

Step 10 Complete the "DLP-B95 Provision a DS-1 Circuit Source and Destination" task on page 16-73.
Step 11 In the Circuit Routing Preferences area (Figure 5-2), uncheck Route Automatically.
Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 16.
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose a Node-Diverse Path option:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, check the Dual Ring Interconnect check box.
Step 15 Click Next. In the VT Matrix Optimization panel, choose one of the following:
•Create VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15327s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Create VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC-1, DS3XM-6, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs aggregate DS-1s onto an STS for handoff to non-ONS 15327 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15327 network, choose one of the following:
–STS grooming node is [source node], VT grooming node is [destination node]—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an OC-N card.
–STS grooming node is [destination node], VT grooming node is [source node]—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
Step 16 Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.
Step 17 Complete the "DLP-B96 Provision a DS-1 or DS-3 Circuit Route" task on page 16-74 for the DS-1 circuit you are creating.
Step 18 Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 13. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.
Step 19 If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears for you to create the remaining circuits. Repeat Steps 5 through 18 for each additional circuit.
Step 20 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.
Step 21 Complete the "B135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 1 Complete the "DLP-B60 Log into CTC" task on page 16-52 at a node on the network where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-B314 Assign a Name to a Port" task on page 19-7. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VT.
•Number of Circuits—Leave the default unchanged (1).
•Auto-ranged—Unavailable when the Number of Circuits field is 1.
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 5-3):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—VT1.5 is the default. You cannot change it.
•Bidirectional—Uncheck for this circuit.
•Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Diagnostic—Leave unchecked.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–IS—Puts the circuit cross-connects in the IS-NR service state.
–OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
–IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
–OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
Note If VT circuit source and destination ports are in an OOS-AU,AINS; OOS-MA,MT; or IS-NR service state, VT circuits in OOS-AU,AINS will change to IS-NR even if a physical signal is not present. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected ports as source and destination choices.

Step 8 Click Next.
Step 9 Complete the "DLP-B95 Provision a DS-1 Circuit Source and Destination" task on page 16-73.
Step 10 In the Circuit Routing Preferences area, uncheck Route Automatically. When Route Automatically is not selected, Using Required Nodes/Spans and Review Route Before Circuit Creation are unavailable.
Step 11 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 15.
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 12 If you selected Fully Protected Path in Step 11 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 13 If you selected Fully Protected Path Step 11 and the circuit will be routed on a path protection DRI, check the Dual Ring Interconnect check box.
Step 14 Click Next. In the VT Optimization Matrix panel, choose one of the following:
•Create VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15327s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Create VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC-1, DS3XM-6, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs aggregate DS-1s onto an STS for handoff to non-ONS 15327 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15327 network, choose one of the following:
–STS grooming node is [source node], VT grooming node is [destination node]—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an OC-N card.
–STS grooming node is [destination node], VT grooming node is [source node]—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
Step 15 Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.
Step 16 Complete the "DLP-B96 Provision a DS-1 or DS-3 Circuit Route" task on page 16-74 for the DS-1 circuit you are creating.
Step 17 Click Finish. CTC completes the circuit. The Circuits window appears.
Step 18 In the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and Search buttons become active.
Step 19 Click Edit (or double-click the circuit row). The Edit Circuit window appears with the General tab selected.
All nodes in the DCC network appear on the network map. Circuit source and destination information appears under the source and destination nodes. To display a detailed view of the circuit, click Show Detailed Map. To move a node icon, select the node, press Ctrl, then drag and drop the icon to the new location.
Step 20 In the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 21 Click Create.
Step 22 In the Define New Drop dialog box, create the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the target card and slot.
c. Port, STS, VT, or DS1—Choose the port, STS, VT, or DS-1 from the Port, STS, VT or DS-1 drop-down lists. The card selected in Step b determines the fields that appear. See Table 5-2 for a list of options.
d. The routing preferences for the new drop match those of the original circuit. However, if the following options are available, you can modify them:
•If the original circuit was routed on a protected path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 12 for option descriptions.
•If the original circuit was not routed on a protected path, the Protection Channel Access option is available. See Step 11 for a description of the PCA option.
e. If you want to change the circuit state, choose the circuit state from the Target Circuit State drop-down list. The state chosen applies to the entire circuit.
f. Check Apply to drop ports if you want to apply the state chosen in the Target Circuit State to the circuit source and destination drops.
g. Click Finish. The new drop appears in the Drops list.
Step 23 If you need to create additional drops for the circuit, repeat Steps 21 and 22 to create the additional drops.
Step 24 Choose Close. The Circuits window appears.
Step 25 Verify that the new drops appear in the Destination column for the circuit you edited. If they do not appear repeat Steps 5 through 24, making sure all options are provisioned correctly.
Step 26 Complete the "B135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.

Step 8 If the circuit will be routed on a path protection, complete the "DLP-B218 Provision Path Protection Selectors During Circuit Creation" task on page 18-11.
Step 9 Click Next.
Step 10 Complete the "DLP-B208 Provision a DS-3 Circuit Source and Destination" task on page 18-7.
Step 11 In the Circuit Routing Preferences area (Figure 5-5), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences:
•Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
•Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.

Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 15.
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "B185 Create a Manually Routed DS-3 Circuit" procedure.
Step 17 Click Finish. One of the following actions occurs based on the circuit properties you selected:
•If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If autoranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue autoranging. After completing the circuits, the Circuits window appears.
•If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears for you to create the remaining circuits. Repeat Steps 5 through 16 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 18 In the Circuits window, verify that the circuits you just created appear in the circuits list.

•Bidirectional—Leave this field checked.
•Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Diagnostic—Leave unchecked.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–IS—Puts the circuit cross-connects in the IS-NR service state.
–OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
–IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
–OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards as source and destination choices.
Step 8 If the circuit will be routed on a path protection, complete the "DLP-B218 Provision Path Protection Selectors During Circuit Creation" task on page 18-11.
Step 9 Click Next.
Step 10 Complete the "DLP-B208 Provision a DS-3 Circuit Source and Destination" task on page 18-7.

•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 15.
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

•Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Diagnostic—Leave unchecked.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–IS—Puts the circuit cross-connects in the IS-NR service state.
–OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
–IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
–OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards as source and destination choices.

Step 8 If the circuit will be routed on a path protection, complete the "DLP-B218 Provision Path Protection Selectors During Circuit Creation" task on page 18-11.
Step 9 Click Next.
Step 10 Complete the "DLP-B208 Provision a DS-3 Circuit Source and Destination" task on page 18-7.
Step 11 Uncheck Route Automatically. When Route Automatically is not selected, Using Required Nodes/Spans and Review Route Before Circuit Creation are unavailable.
Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 15.
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, check the Dual Ring Interconnect check box.
Step 15 Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

Circuit source and destination information appears under the source and destination nodes. To display a detailed view of the circuit, click Show Detailed Map. You can rearrange the node icons by selecting the node with the left mouse button while simultaneously pressing Ctrl, then dragging the icon to the new location.
Step 20 In the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 21 Click Create.
Step 22 In the Define New Drop dialog box, define the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the target card and slot.
c. Port, STS—Choose the port and/or STS from the Port and STS drop-down lists. The card selected in Step b determines whether port, STS, or both display. See Table 5-2 for a list of options.
d. The routing preferences for the new drop will match those of the original circuit. However, if the following options are available, you can modify them:
•If the original circuit was routed on a protected path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 13 for option descriptions.
•If the original circuit was not routed on a protected path, the Protection Channel Access options is available. See Step 12 for a description of the PCA option.
e. If you want to change the circuit state, choose the circuit state from the Target Circuit State drop-down list. The state chosen applies to the entire circuit.
f. Check Apply to drop ports if you want to apply the state chosen in the Target Circuit State to the circuit source and destination drops.
g. Click Finish. The new drop appears in the Drops list.
Step 23 If you need to create additional drops for the circuit, repeat Steps 21 and 22 to create the additional drops.
Step 24 Click Close. The Circuits window appears.
Step 25 Verify that the new drops appear in the Destination column for the circuit you edited. If they do not appear, repeat this procedure, making sure all options are provisioned correctly.
Step 26 Complete the "B135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.

Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create. Define the circuit attributes:
•Circuit Type—Choose STS.
•Number of Circuits—Enter the number of OC-N circuits you want to create. The default is 1. If you are creating multiple circuits with the same source and destination, you can use autoranging to create the circuits automatically.
•Auto-ranged—This check box is automatically checked when you enter more than 1 in the Number of Circuits field. Leave checked if you are creating multiple OC-N circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck this check box if you do not want CTC to create the circuits automatically.
Step 5 Click Next.
Step 6 Define the circuit attributes (Figure 5-9):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—Choose the OC-N circuit size: STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, or STS-48c.
•Bidirectional—Leave checked for this circuit.
•Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VT tunnels and Ethergroup sources and destinations are unavailable.

–OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed to protected drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards as source and destination choices.

Step 9 Complete the "DLP-B97 Provision an OC-N Circuit Source and Destination" task on page 16-75 for the OC-N circuit you are creating.
Step 10 In the Circuit Routing Preferences area (Figure 5-10), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences:
•Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
•Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.
Figure 5-10 Setting Circuit Routing Preferences for an OC-N Circuit
Step 11 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 16.
Step 12 If you selected Fully Protected Path in Step 11 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 13 If you selected Fully Protected Path in Step 11 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box. If not, continue with Step 16.
Step 14 If you checked Using Required Nodes/Spans in Step 10 or Dual Ring Interconnect for a path protection in Step 13, complete the following substeps. If you checked Dual Ring Interconnect for a BLSR or path protection to BLSR handoff, skip this step and continue with Step 15. If you did not select any of these options, continue with Step 16.
a. Click Next.
b. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.
c. Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit will be routed. Click spans twice to change the circuit direction. If you are creating a path protection to BLSR handoff, exclude the unprotected links from the primary node.
d. Repeat Step c for each node or span you wish to include or exclude.
e. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Notes Links lists, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Step 15 If you checked Dual Ring Interconnect for a BLSR or path protection to BLSR handoff in Step 13, complete the following substeps to assign primary and secondary nodes and ring type:
a. In the Circuit Constraints for Automatic Routing area, click Add BLSR DRI.
b. In the confirmation window, click OK.
c. In the Node options area of the BLSR DRI Options dialog box, complete the following (for an example of a traditional and integrated route on primary and secondary nodes, see Figure 5-11):
•Primary Node—For a traditional or integrated BLSR-DRI, choose the node where the circuit interconnects the rings.
•Secondary Node—For a traditional or integrated BLSR-DRI, choose the secondary node for the circuit to interconnect the rings. This route is used if the route on the primary node fails.
•Primary Node #2—For a traditional BLSR-DRI where two primary nodes are required to interconnect rings, choose the second primary node.
•Secondary Node #2—For a traditional BLSR-DRI where two secondary nodes are required, choose the second secondary node.
d. In the Ring and Path Options area, complete the following:
•The first ring is—Choose path protection or BLSR from the drop-down list.
•The second ring is—Choose path protection or BLSR from the drop-down list.
•Use ring interworking protection (RIP) on secondary path—Check this box to carry the secondary spans on the protection channels. These spans will be preempted during a ring/span switch.

e. Click OK. The node information appears in the Required Nodes/Lines list, and the map graphic indicates which nodes are primary and secondary.
f. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.
g. Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit will be routed. Click spans twice to change the circuit direction. If you are creating a path protection to BLSR traditional handoff, exclude the unprotected links from the primary node towards the secondary node. If you are creating a path protection to BLSR integrated handoff, exclude unnecessary DRIs on the path protection segments.
h. Review the circuit constraints. To change the circuit routing order, choose a node in the Required Nodes/Lines lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Step 16 If you selected Review Route Before Creation in Step 10, complete the following substeps; otherwise, continue with Step 17:
a. Click Next.
b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "B262 Create a Manually Routed OC-N Circuit" procedure to assign the circuit route yourself.
Step 17 Click Finish. One of the following results occurs, based on the circuit properties you provisioned in the Circuit Creation dialog box:
•If you entered more than 1 in Number of Circuits and selected Auto-ranged, CTC automatically creates the number of circuits entered in Number of Circuits. If autoranging cannot complete all the circuits, for example, because sequential ports are unavailable on the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue autoranging. After completing the circuits, the Circuits window appears.
•If you entered more than 1 in Number of Circuits and did not choose Auto-ranged, the Circuit Creation dialog box appears for you to create the remaining circuits. Repeat Steps 6 through 16 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 18 In the Circuits window, verify that the circuits you created appear in the circuits list.
Step 19 Complete the "B62 Test OC-N Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 1 Complete the "DLP-B60 Log into CTC" task on page 16-52 at a node on the network where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-B314 Assign a Name to a Port" task on page 19-7. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose STS.
•Number of Circuits—Enter the number of OC-N circuits you want to create. The default is 1.
•Auto-ranged—Applies to automatically routed circuits only. If you entered more than 1 in the Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in Number of Circuits.)
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 5-9):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—Choose the OC-N circuit size. Choices are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, or STS-48c.
•Bidirectional—Leave checked for this circuit.
•Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Diagnostic—Leave unchecked.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–IS—Puts the circuit cross-connects in the IS-NR service state.
–OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
–IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
–OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards as source and destination choices.

•If you are building a multicard EtherSwitch circuit, choose Ethergroup.
•If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.
Step 16 Click Next.
Step 17 In the Circuit VLAN Selection area, click New VLAN. If the desired VLAN already exists, continue with Step 20.
Tip You can also add VLANs in network view by choosing Tools > Manage VLANs. In the All VLANs dialog box, click the Create button to open the Define New VLAN dialog box.
Step 18 In the Define New VLAN dialog box, complete the following:
•VLAN Name—Assign an easily identifiable name to your VLAN.
•VLAN ID—Assign a VLAN ID. The VLAN ID should be the next available number between 2 and 4093 that is not already assigned to an existing VLAN. Each ONS 15327 network supports a maximum of 509 user-provisionable VLANs.
•Topology ID—Choose the topology ID from the drop-down list.
Step 19 Click OK.
Step 20 In the Circuit VLAN Selection area, highlight the VLAN name and click the arrow button (>>) to move the available VLANs to the Circuit VLANs column.
Step 21 If you are building a single-card EtherSwitch circuit and want to disable spanning tree protection on this circuit, uncheck the Enable Spanning Tree check box and click OK on the Disabling Spanning Tree dialog box. The Enable Spanning Tree check box will remain checked or unchecked for the creation of the next single-card point-to-point Ethernet circuits.
Caution Disabling spanning-tree protection increases the likelihood of logic loops on an Ethernet network.
Caution Turning off spanning tree on a circuit-by-circuit basis means that the ONS 15327 is no longer protecting the Ethernet circuit and that the circuit must be protected by another mechanism in the Ethernet network.
Caution Multiple circuits with spanning tree protection enabled incur blocking if the circuits traverse the same E-Series card and use the same VLAN.
Note Spanning-tree rules prevent users from creating new circuits or modifying existing circuits if the circuits do not meet certain VLAN assignment constraints. If the VLAN set of the new circuit overlaps with existing circuits, the same spanning-tree instance is used for all circuits. If the VLAN set of the new circuit overlaps with VLAN sets of existing circuits with different spanning-tree instances, the VLAN assignment fails. Cisco recommends that you plan VLAN assignments so that circuits with larger VLAN sets and a higher chance of overlap are added first. This means that if a circuit with an overlapping VLAN set is added, it collapses into the same spanning tree. To view circuits mapped to a spanning tree and their VLAN assignments, see the "DLP-B8 View Spanning Tree Information" task on page 16-6.
Note You can disable or enable spanning-tree protection on a circuit-by-circuit basis only for single-card, point-to-point Ethernet circuits. Other E-Series Ethernet configurations disable or enable spanning tree on a port-by-port basis.
Step 22 Click Next.
Step 23 In the left pane of the Circuit Routing Preferences panel, confirm that the following information is correct:
•Circuit name
•Circuit type
•Circuit size
•ONS circuit nodes
Step 24 If the information is not correct, click the Back button and repeat Steps 8 through 23 with the correct information. If the information is correct, check Route Automatically.

•Bidirectional—Leave the default unchanged (checked).
•Create cross-connects only (TL1-like)—Uncheck this check box.
•Diagnostic—Leave unchecked.
•Number of Circuits—Leave the default unchanged (1).
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–IS—Puts the circuit cross-connects in the IS-NR service state.
–OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
–IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
–OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-B230 Change a Circuit State" task on page 18-24.
•Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state of the source and destination ports.
Note Loss of signal alarms are generated if ports in the IS-NR service state are not receiving signals.
•Auto-ranged—Unavailable.
