Table 6-1 defines ONS 15454 SDH circuit creation terms and options.
Table 6-1 ONS 15454 SDH Circuit Options
Circuit Option
|
Description
|
Source
|
The circuit source is where the circuit enters the ONS 15454 SDH network.
|
Destination
|
The circuit destination is where the circuit exits an ONS 15454 SDH 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 VC4, VC3, or VC12 for each circuit segment and create circuits from work orders prepared by an operations support system (OSS).
|
Low-order tunnel
|
Low-order tunnels allow VC3 and VC12 circuits to pass through an ONS 15454 SDH without using low-order cross-connect resources on the cross-connect cards. Low-order circuits using tunnels use low-order cross-connect capacity only at the source and destination nodes. One low-order tunnel can carry three VC3s, and each VC3 can contain a VC3 circuit span or 21 VC12 circuit spans.
|
Low-order aggregation point
|
Low-order aggregation points (LAPs) allow low-order VC12 and VC3 circuits to be aggregated into a VC4 for handoff to non-ONS 15454 SDH networks or equipment, such as interoffice facilities (IOFs), switches, or digital access cross-connect systems. The VC4 grooming end of the LAP requires an STM-N card. LAPs can be created on MS-SPRings, 1+1, or unprotected nodes, but cannot be created on SNCP nodes.
|
ONS 15454 SDH circuits are either low-order or high-order circuits. Table 6-2 shows the circuit source and destination options for low-order circuits.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 17-47 at an ONS 15454 SDH on the network where you will create circuits. 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 15454 SDH network, the node icons are stacked on the left side of the graphic area, possibly out of view. Use the scroll bar under 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 "Unknown" 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 5, "Turn Up Network" to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15454 SDH 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 5, "Turn Up Network" and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing. If DCCs need to be created, complete the "DLP-D464 Provision Section DCC Terminations" task on page 21-44.
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 15454 SDH 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 that appear in the shelf map. Verify that the ONS 15454 SDH 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 "DLP-D140 Change the Node Name, Date, Time, and Contact Information" task on page 18-16.
c. Click the Network tab. Verify that the IP address, Subnet mask, Default Router, Prevent LCD IP Config, and Gateway Settings are correctly provisioned. If not, make corrections using the "NTP-D201 Change CTC Network Access" procedure on page 10-2.
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-D203 Modify or Delete Card Protection Settings" procedure on page 10-4.
e. If the node is in an MS-SPRing, click the MS-SPRing tab. (If the node is not in an MS-SPRing, continue with Step f.) Verify that the following items are provisioned as specified in your site plan:
•MS-SPRing type (2-fiber or 4-fiber)
•MS-SPRing ring ID and node IDs
•Ring reversion time
•East and west card assignments
•4-fiber MS-SPRings: span reversion and east/west protect card assignments
If you need to make corrections, see the "NTP-D40 Provision MS-SPRing Nodes" procedure on page 5-10 for instructions.
f. Click the Security tab. Verify that the users and access levels are provisioned as specified. If not, see the "NTP-D30 Create Users and Assign Security" procedure on page 4-3 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-D87 Change SNMP Settings" procedure on page 10-6 to correct the information.
h. Click the Comm Channels tab. Verify that DCCs were created to the applicable STM-N slots and ports. If DCCs were not created for the appropriate STM-N slots and ports, see Chapter 5, "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-D85 Change Node Timing" procedure on page 10-5 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-D71 Create, Download, and Assign Alarm Severity Profiles" procedure on page 7-6 to change the information.
k. Verify that the network element defaults listed in the status area of the node view window are correct.
Step 7 Repeat Step 6 for each node in the network.
Step 8 Complete the appropriate circuit creation procedure from the NTP list in the "Before You Begin" section.
Stop. You have completed this procedure.
NTP-D81 Create an Automatically Routed Low-Order VC12 Circuit
Purpose
|
This procedure creates an automatically routed low-order VC12 circuit, meaning CTC chooses the circuit route based on the parameters you specify and on the software version.
|
Tools/Equipment
|
XC-VXL-10G or XC-VXL-2.5G cards must be installed at the circuit source and destination nodes.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 17-47 at an ONS 15454 SDH on the network where you will create circuit. If you are already logged in, continue with Step 2.
Step 2 On the shelf graphic, verify that XC-VXL-10G or XC-VXL-2.5G cross-connect cards are installed in Slots 8 and 10.
Step 3 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task on page 20-9. If not, continue with Step 4.
Step 4 From the View menu, choose Go to Network View.
Step 5 Click the Circuits tab, then click Create.
Step 6 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VC_LO_PATH_CIRCUIT.
•Number of Circuits—Enter the number of VC-12 circuits you want to create. The default is 1. If you are creating multiple circuits with the same slot and consecutive port numbers, you can use Auto-ranged 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. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.
Step 7 Click Next.
Step 8 Define the circuit attributes (Figure 6-1):
•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—Choose VC12.
•Bidirectional—Leave checked for this circuit (default).
•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, low order tunnels and Ethergroup sources and destinations are unavailable.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance 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 Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.
•Apply to drop ports—Check this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit 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 drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms are generated if Unlocked ports are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC shows only protected cards and ports as source and destination choices.
Figure 6-1 Setting Circuit Attributes for a Low-Order VC12 Circuit
Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task on page 19-11. Otherwise, continue with Step 10.
Step 10 Click Next.
Step 11 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task on page 17-91.
Step 12 In the Circuit Routing Preferences area (Figure 6-2), choose 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 6-2 Setting Circuit Routing Preferences
Step 13 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
•To route the circuit on an MS-SPRing 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 MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.
Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on a SNCP, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, check the Dual Ring Interconnect check box.
Step 16 If you selected Using Required Nodes/Spans in Step 12, complete the following substeps. If not, continue with Step 18.
a. Click Next.
b. In the Circuit Route Constraints For Auto Routing 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 17 Click Next. In the VC LO Matrix Optimization panel, choose one of the following:
•Create VC LO tunnel on transit nodes—This option is available if the VC12 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC12 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•Create VC LO aggregation point—This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A low-order aggregation point (LAP) allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 network, choose one of the following:
–VC4 grooming node is [source node], VC12 grooming node is [destination node]—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.
–VC4 grooming node is [destination node], VC12 grooming node is [source node]—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC12 circuit terminates on an STM-N card.
•None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.
Step 18 If you selected Review Route Before Creation in Step 12, complete the following substeps. If not, continue with Step 19.
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 "D82 Create a Manually Routed Low-Order VC12 Circuit" procedure.
Step 19 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 auto-ranging 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 auto-ranging. 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 so you can create the remaining circuits. Repeat Steps 6 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 20 In the Circuits window, verify that the new circuits appear in the circuits list.
Step 21 Complete the "D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 17-47 at an ONS 15454 SDH on the network where you will create circuit. If you are already logged in, continue with Step 2.
Step 2 On the shelf graphic, verify that XC-VXL-10G or XC-VXL-2.5G cross-connect cards are installed in Slots 8 and 10.
Step 3 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task on page 20-9. If not, continue with Step 4.
Step 4 From the View menu, choose Go to Network View.
Step 5 Click the Circuits tab, then click Create.
Step 6 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VC_LO_PATH_CIRCUIT.
•Number of Circuits—Enter the number of VC12 circuits you want to create. The default is 1. If you are creating multiple circuits with the same slot and consecutive port numbers, you can use Auto-ranged to create the circuits automatically.
•Auto-ranged—This check box is automatically checked if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.
Step 7 Click Next.
Step 8 Define the circuit attributes (Figure 6-1):
•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—Choose VC12.
•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, low order tunnels and Ethergroup sources and destinations are unavailable.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance 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 Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.
•Apply to drop ports—Select this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit 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 drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms are generated if Unlocked ports are not receiving signals.
•Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC shows only protected cards and ports as source and destination choices.
Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task on page 19-11. Otherwise, continue with Step 10.
Step 10 Click Next.
Step 11 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task on page 17-91.
Step 12 In the Circuit Routing Preferences area (Figure 6-2), uncheck Route Automatically.
Step 13 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 17.
•To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 17.
Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.
Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on a SNCP, choose a Node-Diverse Path option:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.
Step 16 Click Next. In the VC LO Matrix Optimization panel, choose one of the following:
•Create VC LO tunnel on transit nodes—This option is available if the VC12 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC12 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•Create VC LO aggregation point—This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A low-order aggregation point (LAP) allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto a VC4 for transport outside the ONS 15454 SDH network, choose one of the following:
–VC4 grooming node is [source node], VC12 grooming node is [destination node]—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.
–VC4 grooming node is [destination node], VC12 grooming node is [source node]—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC12 circuit terminates on an STM-N card.
•None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.
Step 17 Click Next. In the Route Review/Edit area, node icons appear for circuit routing. 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 18 Complete the "DLP-D3 Provision a Low-Order VC12 Circuit Route" task on page 17-2 for the VC12 circuit you are creating.
Step 19 Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 14. 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 20 If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 19 for each additional circuit.
Step 21 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.
Step 22 Complete the "D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 7 Click Next.
Step 8 Define the circuit attributes:
•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 VC12.
•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, low order tunnels and Ethergroup sources and destinations are unavailable.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit 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 drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if Unlocked ports are not receiving signals.
•Protected Drops—Check this box if you want the circuit routed to protect drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this box, CTC displays only protected cards as source and destination choices.
Step 9 Click Next.
Step 10 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task on page 17-91.
Step 11 In the Circuit Routing Preferences area, uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.
Step 12 Set the circuit path protection:
•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 SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
•To route the circuit on an MS-SPRing 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 MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a SNCP, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring 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 an SNCP DRI, click the Dual Ring Interconnect check box.
Step 15 Click Next. In the VC LO Matrix Optimization panel, choose one of the following:
•Create VC LO tunnel on transit nodes—This option is available if the VC12 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC12 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•Create VC LO aggregation point—This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A low-order aggregation point (LAP) allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:
–VC4 grooming node is [source node], VC12 grooming node is [destination node]—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.
–VC4 grooming node is [destination node], VC12 grooming node is [source node]—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC12 circuit terminates on an STM-N card.
•None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.
Step 16 Click Next. In the Route Review and Edit area, node icons appear so you can 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 17 Complete the "DLP-D3 Provision a Low-Order VC12 Circuit Route" task on page 17-2 for the VC12 circuit you are creating.
Step 18 Click Finish. CTC completes the circuit and the Circuits window appears.
Step 19 In the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and Search buttons become active.
Step 20 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. Circuit source and destination information appears under the source and destination nodes. To see a detailed view of the circuit, click Show Detailed Map. To rearrange a node icon, select the node, press Ctrl, then drag and drop the icon to the new location.
Step 21 In the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.

Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task on page 19-11. Otherwise, continue with Step 10.
Step 10 Click Next.
Step 11 Complete the "DLP-D318 Provision a Low-Order VC3 Circuit Source and Destination" task on page 20-11.
Step 12 In the Circuit Routing Preferences area (Figure 6-2), choose 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.
Step 13 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
•To route the circuit on an MS-SPRing 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 MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.
Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on a SNCP, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.
Step 16 If you selected Using Required Nodes/Spans in Step 12, complete the following substeps. If not, continue with Step 18.
a. Click Next.
b. In the Circuit Route Constraints For Auto Routing 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 is 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 17 Click Next. In the VC LO Matrix Optimization panel, choose one of the following:
•Create VC LO tunnel on transit nodes—This option is available if the VC3 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC3 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•Create VC LO aggregation point—This option is available if you are creating a VC3 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A low-order aggregation point (LAP) allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:
–VC4 grooming node is [source node], VC12 grooming node is [destination node]—Creates the LAP on the VC3 circuit source node. This option is available only if the VC3 circuit originates on an STM-N card.
–VC4 grooming node is [destination node], VC12 grooming node is [source node]—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC3 circuit terminates on an STM-N card.
•None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.
Step 18 If you selected Review Route Before Creation in Step 12, complete the following substeps. If not, continue with Step 19.
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 "D82 Create a Manually Routed Low-Order VC12 Circuit" procedure.
Step 19 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 auto-ranging 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 auto-ranging. 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 so you can create the remaining circuits. Repeat Steps 6 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 20 In the Circuits window, verify that the new circuits appear in the circuits list.
Step 21 Complete the "D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 5 Click the Circuits tab, then click Create.
Step 6 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VC_LO_PATH_CIRCUIT.
•Number of Circuits—Enter the number of VC3 circuits you want to create. The default is 1. If you are creating multiple circuits with the same slot and consecutive port numbers, you can use Auto-ranged 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. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.
Step 7 Click Next.
Step 8 Define the circuit attributes (Figure 6-3):
•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—Choose VC3.
•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, low order tunnels and Ethergroup sources and destinations are unavailable.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance 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 Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.
•Apply to drop ports—Select this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit 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 drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms are generated if Unlocked ports are not receiving signals.
•Protected Drops—Select this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you select this check box, CTC displays only protected cards and ports as source and destination choices.
Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task on page 19-11. Otherwise, continue with Step 10.
Step 10 Click Next.
Step 11 Complete the "DLP-D318 Provision a Low-Order VC3 Circuit Source and Destination" task on page 20-11.
Step 12 In the Circuit Routing Preferences area (Figure 6-2), uncheck Route Automatically.
Step 13 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 17.
•To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 17.
Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.
Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on a SNCP, choose a Node-Diverse Path option:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.
Step 16 Click Next. In the VC LO Matrix Optimization panel, choose one of the following:
•Create VC LO tunnel on transit nodes—This option is available if the VC3 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC3 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•Create VC LO aggregation point—This option is available if you are creating a VC3 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A low-order aggregation point (LAP) allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:
–VC4 grooming node is [source node], VC12 grooming node is [destination node]—Creates the LAP on the VC3 circuit source node. This option is available only if the VC3 circuit originates on an STM-N card.
–VC4 grooming node is [destination node], VC3 grooming node is [source node]—Creates the LAP on the VC3 circuit destination node. This option is available only if the VC3 circuit terminates on an STM-N card.
•None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.
Step 17 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 18 Complete the "DLP-D96 Provision a Low-Order VC3 Circuit Route" task on page 17-93 for the VC3 circuit you are creating.
Step 19 Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 14. 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 20 If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 19 for each additional circuit.
Step 21 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.
Step 22 Complete the "D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 7 Click Next.
Step 8 Define the circuit attributes (Figure 6-4):
•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 VC3.
•Bidirectional—Uncheck for this circuit.
•Number of Circuits—Leave the default unchanged (1).
•Auto-ranged—Unavailable when the Number of Circuits field is 1.
•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, low order tunnels and Ethergroup sources and destinations are unavailable.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance 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 Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit 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 drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if Unlocked ports are not receiving signals.
•Protected Drops—Check this box if you want the circuit routed to protect drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this box, CTC displays only protected cards as source and destination choices.

Step 9 Click Next.
Step 10 Complete the "DLP-D318 Provision a Low-Order VC3 Circuit Source and Destination" task on page 20-11.
Step 11 In the Circuit Routing Preferences area, uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.
Step 12 Set the circuit path protection:
•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 SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
•To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 16.
Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a SNCP, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring 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 an SNCP DRI, click the Dual Ring Interconnect check box.
Step 15 Click Next. In the VC LO Matrix Optimization panel, choose one of the following:
•Create VC LO tunnel on transit nodes—This option is available if the VC3 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC3 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•Create VC LO aggregation point—This option is available if you are creating a VC3 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A low-order aggregation point (LAP) allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:
–VC4 grooming node is [source node], VC12 grooming node is [destination node]—Creates the LAP on the VC3 circuit source node. This option is available only if the VC3 circuit originates on an STM-N card.
–VC4 grooming node is [destination node], VC12 grooming node is [source node]—Creates the LAP on the VC3 circuit destination node. This option is available only if the VC3 circuit terminates on an STM-N card.
•None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.
Step 16 Click Next. In the Route Review and Edit area, node icons appear so you can 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.

NTP-D187 Create a Low-Order Aggregation Point
Purpose
|
This procedure creates a low-order aggregation point (LAP). LAPs allow multiple VC3 or VC12 low-order circuits to be aggregated on a single VC4 circuit. LAPs allow multiple low-order circuits to pass through cross-connect cards without utilizing resources on the cross-connect card low-order matrix.

Note You can create low-order aggregation points for circuits in MS-SPRing or 1+1 protection, or for unprotected circuits. You cannot create them for SNCP ring circuits.
Note The maximum number of LAPs that you can create depends on the node protection topology and number of low-order circuits that terminate on the node. Assuming no other low-order circuits terminate at the node, the maximum number of LAPs that you can terminate at one node is 8 for 1+1 and 12 for MS-SPRing protection.
Step 1 Complete the "DLP-D60 Log into CTC" task on page 17-47 at an ONS 15454 SDH on the network where you will create 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-D314 Assign a Name to a Port" task on page 20-9. If not, continue with Step 3.

•Size—Defaults to VC4. You cannot change the value.
•Bidirectional—Defaults to Bidirectional. You cannot change the value.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance 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 Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.

Step 3 Click the Circuit tab.
Step 4 Complete the "DLP-D230 Change a Circuit State" task on page 19-19 and set the circuit ports to the Locked-enabled,maintenance service state. Take note of the original state because you will return the circuit to that state later.
Step 5 Attach loopback cables to the circuit destination card.
a. Verify the integrity of the loopback cable by looping the test set transmit (Tx) connector to the test set receive (Rx) connector. If the test set does not run error-free, check the cable for damage and check the test set to make sure it is set up correctly before going to Step b.
b. Attach the loopback cable to the port you are testing. Connect the Tx connector to the Rx connector of the port.
Step 6 Attach loopback cables to the circuit source node.
a. Verify the integrity of loopback cable by looping the test set Tx connector to the test set Rx connector. If the test set does not run error-free, check the cable for damage and check the test set to make sure it is set up correctly before going to Step b.
b. Attach the loopback cable to the port you are testing. Connect the test set to the circuit source port. Connect the Tx port of the test set to the circuit Rx port and the test set Rx port to the circuit Tx port.
Step 7 Configure the test set for the ONS 15454 SDH card that is the source of the circuit you are testing:
•VC4 or VC4-nc—If you are testing a VC4 circuit or a VC4-nc circuit on an STM-N card, you must have a direct optical interface into the ONS 15454 SDH. Set the test set for STM-N. For information about configuring your test set, consult your test set user guide.
•VC3—If you are testing a clear channel E3/DS3i-N-12, you must have a patch panel or a direct E3/DS3i-N-12 interface into the ONS 15454 SDH. Set the test set for clear channel E3/DS3i-N-12. For information about configuring your test set, consult your test set user guide.
•VC12—If you are testing an E1, you must have a patch panel or a direct E1 interface to the ONS 15454 SDH. Set the test set for E1. For information about configuring your test set, consult your test set user guide.
Step 8 Verify that the test set has a clean signal. If a clean signal is not shown, repeat Steps 4 through 7 to make sure the test set and cabling are configured correctly.
Step 9 Inject errors from the test set. Verify that the errors appear at the source and destination nodes.
Step 10 Clear the performance monitoring (PM) counts for the ports that you tested. See the "DLP-D459 Clear Selected PM Counts" task on page 21-39 for instructions.
Step 11 Complete the "DLP-D230 Change a Circuit State" task on page 19-19 and put the circuit and circuit ports back to the state they were in at the beginning of the test.

Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VC_HO_PATH_CIRCUIT.
•Number of Circuits—Enter the number of high-order circuits you want to create. The default is 1. If you are creating multiple circuits with the same source and destination, you can use auto-ranging to create the circuits automatically.
•Auto-ranged—This check box is automatically selected when you enter more than 1 in the Number of Circuits field. Leave this check box selected if you are creating multiple high-order circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck the box if you do not want CTC to create the circuits automatically.
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 6-7):
•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 high-order circuit size: VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-9c, VC4-16c, or VC4-64c.
•Bidirectional—Leave checked for this circuit (default).
•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, low order tunnels and Ethergroup sources and destinations are unavailable.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance 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 Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit 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 drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if Unlocked ports are not receiving signals.
•Protected Drops—Select this check box if you want the circuit routed to protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you select this check box, CTC shows only protected cards as source and destination choices.

Step 8 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task on page 19-11.
Step 9 Click Next.
Step 10 Complete the "DLP-D97 Provision a High-Order Circuit Source and Destination" task on page 17-94 for the high-order circuit you are creating.
Step 11 In the Circuit Routing Preferences area, 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 Set the circuit path protection:
•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 SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on SNCP, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring 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 an MS-SPRing DRI or SNCP DRI, check the Dual Ring Interconnect check box. If not, continue with Step 17.
Step 15 If you checked Dual Ring Interconnect for a SNCP in Step 14, complete the following substeps. If you checked Dual Ring Interconnect for a MS-SPRing, skip this step and continue with Step 16.
a. Click Next.
b. In the Circuit Route Constraints For Auto 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 is 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, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Step 16 If you checked Dual Ring Interconnect for a MS-SPRing in Step 14, complete the following substeps to assign primary and secondary nodes and ring type.
a. In the Circuit Constraints for Automatic Routing area, click Add MS-SPRing DRI.
b. In the confirmation window, click OK.
c. In the Node Options area of the MS-SPRing DRI Options dialog box, complete the following (for an example of a traditional and integrated route on primary and secondary nodes):
•Primary Node—For a traditional or integrated MS-SPRing DRI, choose the node where the circuit interconnects the rings.
•Secondary Node—For a traditional or integrated MS-SPRing 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 MS-SPRing DRI where two primary nodes are required to interconnect rings, choose the second primary node.
•Secondary Node #2—For a traditional MS-SPRing 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 SNCP or MS-SPRing from the drop-down list.
•The second ring is—Choose SNCP or MS-SPRing 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 an SNCP to MS-SPRing traditional handoff, exclude the unprotected links from the primary node towards the secondary node. If you are creating an SNCP to MS-SPRing integrated handoff, exclude unnecessary DRIs on the SNCP 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 17 If you selected Review Route Before Creation in Step 11, complete the following substeps; otherwise, continue with Step 19:
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 "D324 Create a Manually Routed High-Order Circuit" procedure to assign the circuit route yourself.
Step 18 If you selected Review Route Before Creation in Step 11, click Next. If not, continue with Step 19. View the route in the Route Review/Edit window. As necessary, click Add MS-SPRing DRI to add another DRI. Click Remove to remove a DRI assignment. Click the Included Spans tab to view the spans. The map graphic updates as you apply changes.
Step 19 Click Finish. One of the following occurs, based on the circuit properties you provisioned 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 Number of Circuits. If auto-ranging 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 auto-ranging. 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 so you can create the remaining circuits. Repeat Steps 5 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 20 In the Circuits window, verify that the circuits you created appear in the circuits list.
Step 21 Complete the "D62 Test High-Order Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 17-47 at an ONS 15454 SDH on the network where you will create 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-D314 Assign a Name to a Port" task on page 20-9. 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 VC_HO_PATH_CIRCUIT.
•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:
•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 high-order circuit size: VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-9c, VC4-16c, VC4-64c.
•Bidirectional—Uncheck this check box 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, low order tunnels and Ethergroup sources and destinations are unavailable.
•State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance 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 Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 19-19.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit 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 drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if Unlocked ports are not receiving signals.
•Protected Drops—Select this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you select this check box, CTC shows only protected cards as source and destination choices.
Step 8 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task on page 19-11.
Step 9 Click Next.
Step 10 Complete the "DLP-D97 Provision a High-Order Circuit Source and Destination" task on page 17-94 for the circuit you are creating.
Step 11 Uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.
Step 12 Set the circuit path protection:
•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 SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.
Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a SNCP, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring 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 SNCP ring portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Note For manually routed circuits, CTC checks your manually provisioned path against the path diversity option you choose. If the path does not meet the path diversity requirement that is specified, an error message appears.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.
Step 15 Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually. The green arrows pointing from the selected node to other network nodes indicate spans that are available for routing the circuit.
Step 16 Complete the "DLP-D98 Provision a High-Order Circuit Route" task on page 17-95.
Step 17 Click Finish. After completing 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. The Edit Circuit window appears with the General tab selected. Nodes in the DCC network are shown graphically. Circuit source and destination information appears under the source and destination nodes. To see a detailed view of the circuit, click Show Detailed Map. You can rearrange the node icons by pressing Ctrl while you 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, define the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the target card and slot.
c. Port, VC4—Choose the port and/or VC4 from the Port and VC4 drop-down lists. The choice in these menus depends on the card selected in Step b. See Table 6-2 for a list of options.
d. The routing preferences for the new drop match those of the original circuit. However, you can modify the following:
•If the original circuit was routed on a protected SNCP path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 13 for descriptions.
•If the original circuit was not routed on a protected path, the Protection Channel Access option is available. See Step 12 for a description of the PCA option.
e. Click OK. The new drop appears in the Drops list.
Step 23 If you need to create additional drops on the circuit, repeat Steps 20 through 22.
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 Steps 21 through 24 making sure all options are provisioned correctly.

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 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 15454 SDH network supports a maximum of 509 user-provisionable VLANs.
•Topology Host—Choose the topology host ID from the drop-down list.

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 box remains checked or unchecked for the creation of the next single-card, point-to-point Ethernet circuit.
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 15454 SDH 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-D23 View Spanning Tree Information" task on page 17-19.
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 Confirm that the following information about the circuit is correct:
•Circuit name
•Circuit type
