Table 8-1 defines ONS 15454 SDH circuit creation terms and options.
Table 8-1 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
|
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 cross-connect card (XC10G and XCVXL) resources. Low-order- circuits using tunnels will use cross-connect capacity only at the source and destination nodes. One low-order tunnel can carry three VC3s, and each VC3 can carry 21 VC12s. One tunnel can carry one VC3 circuit span and 42 VC12 circuit spans, and each VC3 is a separate container that 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 hand off to non-ONS 15454 networks or equipment, such as inter office facilities (IOFs), switches, or digital access cross-connect systems, (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 8-2 shows the circuit source and destination options for low-order circuits.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23 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 may 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 will be 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 grey 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 grey, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see Chapter 6, "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 grey in color, do not continue. See Chapter 6, "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-D253 Provision SDH DCC Terminations" task on page 6-5.
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 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 12-2.
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 12-4.
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 12-15.
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" task on page 6-15 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 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 12-31 to correct the information.
h. Click the DCC/GCC 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 6, "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 12-22 to make the changes.
j. Click the Alarm Behavior 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 9-17 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 on page 8-1.
Stop. You have completed this procedure.
NTP-D81 Create an Automatically Routed Low-Order VC12 Circuit

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23 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 Complete the "DLP-D317 Verify XCVXL Card Installation" task.
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. 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:
•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.
•Type—Choose VC_LO_PATH_CIRCUIT.
•Size—Choose VC12.
•Bidirectional—Leave checked for this circuit (default).
•Number of Circuits—Type 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 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.
•State—Choose a service state to apply to the circuit:
–IS—The circuit is in service.
–OOS—The circuit is out of service. Traffic is not passed on the circuit.
–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
–OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
Note If low-order circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, low-order circuits in OOS_AINS will change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•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 will apply 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 will not change the state of the source and destination ports.
Note Loss of Signal alarms are generated if in service (IS) ports are not receiving signals.
•Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•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 shows only protected cards and ports as source and destination choices.
Step 7 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 8.
Step 8 Click Next.
Step 9 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task.
Step 10 In the Circuit Routing Preferences area (Figure 8-1), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.
•Using Required Nodes/Spans—Select this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.
•Review Route Before Creation—Select this check box if you want to review and edit the circuit route before the circuit is created.
Step 11 Set the circuit path protection:
•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 may or may 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 14.
•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 14.
Caution Circuits routed on MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.
Step 12 If you selected Fully Protected Path in Step 10, 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 may be node-diverse, but CTC does not check for node diversity.
Figure 8-1 Setting Circuit Routing Preferences for a Low-Order VC12 Circuit
Step 13 If you selected Fully Protected Path and the circuit will be routed on an SNCP dual ring interconnect (DRI), click the Dual Ring Interconnect check box.
Step 14 If you selected Using Required Nodes/Spans in Step 10, 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 15 Click Next. In the Low-Order Circuit area under Create, choose one of the following:
•Low-Order 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 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.
•Low-Order Aggregation Point—This option is available if you are creating a VC12 circuit to an STM-N port for hand off to non-ONS 15454 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 low-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:
–Use source as the VC4 grooming end—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.
–Use destination as the VC4 grooming end—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 will be the only available option if CTC cannot create a low-order tunnel or LAP.
Step 16 If you chose low-order Aggregation Point, complete the following substeps. If not, continue with Step 17.
a. Click Next.
b. On the Low-Order Aggregation Point Destination panel, click the node that you want to be the LAP destination, then click Add Destination.
Step 17 If you selected Review Route Before Creation in Step 10, 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 "D82 Create a Manually Routed Low-Order VC12 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 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.
•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 this procedure for each additional circuit.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23 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 Complete the "DLP-D317 Verify XCVXL Card Installation" task.
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. 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:
•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.
•Type—Choose VC_LO_PATH_CIRCUIT.
•Size—Choose VC12.
•Number of Circuits—Type 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 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.
•State—Choose a service state to apply to the circuit:
–IS—The circuit is in service.
–OOS—The circuit is out of service. Traffic is not passed on the circuit.
–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
–OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
Note If low-order circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, low-order circuits in OOS_AINS will change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•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 will apply 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 will not change the state of the source and destination ports.
Note Loss of Signal alarms are generated if in service (IS) ports are not receiving signals.
•Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•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 shows only protected cards and ports as source and destination choices.
Step 7 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 8.
Step 8 Click Next.
Step 9 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task.
Step 10 In the Circuit Routing Preferences area (see Figure 8-1), uncheck Route Automatically.
Step 11 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12. Fully-protected paths may or may 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 12 If you selected Fully Protected Path, 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 may be node-diverse, but CTC does not check for node diversity.
Step 13 If you selected Fully Protected Path and the circuit will be routed on an SNCP dual ring interconnect (DRI), click the Dual Ring Interconnect check box.
Step 14 Click Next. In the Low-Order Circuit area under Create, choose one of the following:
•Low-Order 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 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.
•Low-Order Aggregation Point—This option is available if you are creating a VC12 circuit to an STM-N port for hand off to non-ONS 15454 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 low-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:
–Use source as the VC4 grooming end—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.
–Use destination as the VC4 grooming end—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 will be the only available option if CTC cannot create a low-order tunnel or LAP.
Step 15 If you chose Low-Order Aggregation Point, complete the following substeps. If not, continue with Step 16.
a. Click Next.
b. On the Low-Order Aggregation Point Destination panel, click the node that you want to be the LAP destination, then click Add Destination.
Step 16 Click Next. In the Route Review and 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 17 Complete the "DLP-D96 Provision a Low-Order VC3 Circuit Route" task for the VC12 circuit you are creating.
Step 18 Click Finish. CTC will compare your manually-provisioned circuit route with the specified path diversity option you chose in Step 12. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path. 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 this procedure for each additional circuit.
Step 19 When all the circuits are created, the main Circuits window appears. Verify that the circuit(s) you created are correct.
Step 20 Complete the "D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12. Fully-protected paths may or may 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 11 If you selected Fully Protected Path, 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 may be node-diverse, but CTC does not check for node diversity.
Step 12 If you selected Fully Protected Path and the circuit will be routed on an SNCP dual ring interconnect (DRI), click the Dual Ring Interconnect check box.
Step 13 Click Next. In the Low-Order Circuit area under Create, choose one of the following:
•Low-Order 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 cross-connect card resources.

Step 5 From the TUG2 drop-down menu, choose the source TUG2.
Step 6 From the VC12 drop-down menu, choose the source VC12.
Step 7 If you need to create a secondary source, for example, an SNCP ring bridge/selector circuit entry point in a multivendor SNCP ring, click Use Secondary Source and repeat Steps 1 through 5 to define the secondary source. If you do not need to create a secondary source, continue with Step 8.
Step 8 Click Next.
Step 9 From the Node drop-down menu, choose the destination (termination) node.
Step 10 From the Slot drop-down menu, choose the slot containing the destination card. The destination is typically a E1 card. However, you can also choose an STM-N card to map the VC12 to a VC4 for optical transport.
Step 11 Depending on the destination card, choose the destination port from the sub-menus that appear based on the card selected in Step 10. See Table 8-2 for a list of valid options. CTC does not show ports, VC4s, TUG3s, TUG2s, or VC12s already used by other circuits. If you and a user working on the same network choose the same VC4, TUG3, TUG2, or VC12 simultaneously, one of you will receive a Path in Use error and be unable to complete the circuit. The user with the incomplete circuit needs to choose new destination parameters.
Step 12 If you need to create a secondary destination, for example, an SNCP ring bridge/selector circuit exit point in a multivendor SNCP ring, click Use Secondary Destination and repeat Steps 9 through 11 to define the secondary destination.
Step 13 Click Next.

Step 5 Click the Circuits tab, then click Create.
Step 6 In the Circuit Creation dialog box (Figure 8-4), complete the following fields:
•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.
•Type—Choose VC_LO_PATH_CIRCUIT.
•Size—Choose VC3.
•Number of Circuits—Type 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.
•State—Choose a service state to apply to the circuit:
–IS—The circuit is in service.
–OOS—The circuit is out of service. Traffic is not passed on the circuit.
–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
–OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
Note If low-order circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, low-order circuits in OOS_AINS will change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•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.

•Review Route Before Creation—Select this check box if you want to review and edit the circuit route before the circuit is created.
Step 11 Set the circuit path protection:
•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 may or may 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 14.
•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 14.
Caution Circuits routed on MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.
Step 12 If you selected Fully Protected Path in Step 10, 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 may be node-diverse, but CTC does not check for node diversity.
Figure 8-5 Setting Circuit Routing Preferences for a Low-Order VC3 Circuit
Step 13 If you selected Fully Protected Path and the circuit will be routed on an SNCP dual ring interconnect (DRI), click the Dual Ring Interconnect check box.
Step 14 If you selected Using Required Nodes/Spans in Step 10, 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 15 Click Next. In the Low-Order Circuit area under Create, choose one of the following:
•Low-Order 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 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.
•Low-Order Aggregation Point—This option is available if you are creating a VC12 circuit to an STM-N port for hand off to non-ONS 15454 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 low-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:
–Use source as the VC4 grooming end—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.
–Use destination as the VC4 grooming end—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 will be the only available option if CTC cannot create a low-order tunnel or LAP.
Step 16 If you chose low-order Aggregation Point, complete the following substeps. If not, continue with Step 17.
a. Click Next.
b. On the Low-Order Aggregation Point Destination panel, click the node that you want to be the LAP destination, then click Add Destination.
Step 17 If you selected Review Route Before Creation in Step 10, 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 "D82 Create a Manually Routed Low-Order VC12 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 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.
•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 this procedure for each additional circuit.
•After completing the circuit(s), the Circuits window appears.
Step 19 On the Circuits window, verify that the new circuit(s) appear in the circuits list.
Step 20 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 3-23 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 Complete the "DLP-D317 Verify XCVXL Card Installation" task.
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. 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 (Figure 8-4), complete the following fields:
•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.
•Type—Choose VC_LO_PATH_CIRCUIT.
•Size—Choose VC3.
•Number of Circuits—Type 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.
•State—Choose a service state to apply to the circuit:
–IS—The circuit is in service.
–OOS—The circuit is out of service. Traffic is not passed on the circuit.
–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
–OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
Note If low-order circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, low-order circuits in OOS_AINS will change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.
•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 will apply 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 will not change the state of the source and destination ports.
Note Loss of Signal alarms are generated if in service (IS) ports are not receiving signals.
•Inter-domain (UCP) SLA—If the circuit will travel on a unified control plan e (UCP) channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•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 7 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 8.
Step 8 Click Next.
Step 9 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task.
Step 10 In the Circuit Routing Preferences area (see Figure 8-1), uncheck Route Automatically.
Step 11 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12. Fully-protected paths may or may 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 12 If you selected Fully Protected Path in Step 11, 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 may 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 an SNCP dual ring interconnect (DRI), click the Dual Ring Interconnect check box.
Step 14 Click Next. In the Low-Order Circuit area under Create, choose one of the following:
•Low-Order 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 cross-connect card resources.

•Low-Order Aggregation Point—This option is available if you are creating a VC12 circuit to an STM-N port for hand off to non-ONS 15454 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 low-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:
–Use source as the VC4 grooming end—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.
–Use destination as the VC4 grooming end—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 will be the only available option if CTC cannot create a low-order tunnel or LAP.
Step 15 If you chose Low-Order Aggregation Point in Step 14, complete the following substeps. If not, continue with Step 16.
a. Click Next.
b. In the Select Low-Order Grooming Node area, click the node that you want to be the LAP grooming node, then click Add Destination.
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-D96 Provision a Low-Order VC3 Circuit Route" task for the VC3 circuit you are creating.
Step 18 Click Finish. CTC will compare your manually-provisioned circuit route with the specified path diversity option you chose in Step 12. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path. 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 this procedure for each additional circuit.
Step 19 When all the circuits are created, the main Circuits window appears. Verify that the circuit(s) you created are correct.
Step 20 Complete the "D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.

Step 1 On the Circuit Attributes panel of the Circuit Creation wizard, set the SNCP path selectors:
•Revertive—Check this box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If you do not choose Revertive, traffic remains on the protect path after the switch.
•Reversion time—If Revertive is checked, click the Reversion time field and choose a reversion time from the drop-down menu. The range is 0.5 to 12.0 minutes. The default is 5.0 minutes. This is the amount of time that will elapse before the traffic reverts to the working path. Traffic can revert when conditions causing the switch are cleared.
•SF threshold—For high-order circuits, set the SNCP path-level signal failure bit error rate (BER) thresholds. Unavailable for low-order circuits.
•SD threshold—For high-order circuits, set the SNCP path-level signal degrade BER thresholds. Unavailable for low-order circuits.
•Switch on PDI-P—For high-order circuits, check this box if you want traffic to switch when an high-order payload defect indicator is received. Unavailable for low-order circuits.
Step 2 Return to your originating procedure (NTP).
DLP-D218 Provision a Low-Order VC3 Circuit Source and Destination
Note After you have selected the circuit properties in the Circuit Source dialog box according to the specific circuit creation procedure, you are ready to provision the circuit source.
Step 1 From the Node drop-down menu, choose the node where the source will originate.
Step 2 From the Slot drop-down menu, choose the slot containing the E3-12 or DS3i-N-12 card where the circuit will originate. Figure 8-7 shows an example circuit source for an E3-12 card.
Figure 8-7 Defining the Circuit Source on a E3-12 Card
Step 3 Choose the port from the Port drop-down menu.
Step 4 Choose the VC4 from the VC4 drop-down menu.
Step 5 Choose the VC3 from the VC3 drop-down menu.
Step 6 If you need to create a secondary source, for example, an SNCP ring bridge/selector circuit entry point in a multivendor SNCP ring, click Use Secondary Source and repeat Steps 1 through 5 to define the secondary source. If you do not need to create a secondary source, continue with Step 8.
Step 7 Click Next.
Step 8 From the Node drop-down menu, choose the destination (termination) node.
Step 9 From the Slot drop-down menu, choose the slot containing the destination card. The destination is typically a E3 or DS3 card. However, you can also choose an STM-N card to map the VC3 to a VC4 for optical transport.
Step 10 Depending on the destination card, choose the destination port from the sub-menus that appear based on the card selected in Step 2. See Table 8-2 for a list of valid options. CTC does not show ports, VC4s, or VC3s already used by other circuits. If you and a user working on the same network choose the same port, VC4, or VC3 simultaneously, one of you will receive a Path in Use error and be unable to complete the circuit. The user with the incomplete circuit needs to choose new destination parameters.
Step 11 If you need to create a secondary destination, for example, an SNCP ring bridge/selector circuit exit point in a multivendor SNCP ring, click Use Secondary Destination and repeat Steps 9 through 11 to define the secondary destination.
Step 12 Click Next.
Step 13 Return to your originating procedure (NTP).
DLP-D96 Provision a Low-Order VC3 Circuit Route
Step 1 On the Circuit Creation wizard in the Route Review and Edit area, click the source node icon if it is not already selected.
Step 2 Starting with a span on the source node, click the arrow of the span you want the circuit to travel. The arrow turns white. In the Selected Span area, the From and To fields provide span information. The source VC3 appears.
Step 3 If you want to change the source VC3, adjust the Source VC3 field; otherwise, continue with Step 4.
Step 4 If you want to change the source VC4, adjust the Source VC4 field; otherwise, continue with Step 5.
Step 5 Click Add Span.The span is added to the Included Spans list and the span arrow turns blue.
Step 6 Repeat Steps 2 through 5 until the circuit is provisioned from the source to the destination node through all intermediary nodes. If Fully Protect Path is checked on the Circuit Routing Preferences panel, you must:
•Add two spans for all SNCP ring or unprotected portions of the circuit route from the source to the destination. If the Dual Ring Interconnect check box is checked, you must also add bidirectional spans between the DRI nodes. To do this, click a DRI node, then double-click the arrow pointing to the adjacent DRI node to create a bidirectional span.
•Add one span for all MS-SPRing or 1+1 portions of route from the source to the destination
Step 7 Return to your originating procedure (NTP).

Note Low-order tunnels allow low-order VC12 and VC3 circuits to pass through intermediary ONS 15454 SDH nodes without consuming low-order matrix resources on the cross-connect card. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Low-order tunnels are required if low-order circuits must pass through nodes with XC10G cross-connect cards. Refer to the Circuits and Tunnels chapter in the Cisco ONS 15454 SDH Reference Manual for more information.
Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23 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. If not, continue with Step 4.
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 (Figure 8-8), complete the following fields:
•Name—Assign a name to the low-order tunnel. 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 tunnel.
•Type—Choose VC_LO_PATH TUNNEL. The Bidirectional, Number of Circuits, and Field Size fields in the dialog box become unavailable.
•Size—The default size is VC4. You cannot change this value.
•For VC3 Port Grouping Only—Leave this box unchecked.

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 (Figure 8-10), complete the following fields:
•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.
•Type—Choose VC_HO_PATH_CIRCUIT.
•Size—Choose the high-order circuit size: VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-16c, or VC4-64c.
•Bidirectional—Leave checked for this circuit (default).
•Number of Circuits—Type 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.
•State—Choose a service state to apply to the circuit:
•IS—The circuit is in service.
•OOS—The circuit is out of service. Traffic is not passed on the circuit.
•OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
•OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
•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 will apply 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 will not change the state of the source and destination ports.
Note Loss of Signal alarms appear if in service (IS) ports are not receiving signals.
•Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•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.

•Review Route Before Creation—Choose this check box to review and edit the circuit route before the circuit is created.
Step 10 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 11. CTC creates a fully-protected circuit route based on the path diversity option you choose. Fully-protected paths may or may 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 13.
•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 13.
Step 11 If you selected Fully Protected Path, 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 may be node-diverse, but CTC does not check for node diversity.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23 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 circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 In the Circuit Creation dialog box, complete the following fields:
•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.
•Type—Choose VC_HO_PATH_CIRCUIT.
•Size—Choose the high-order circuit size: VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-16c, or VC4-64c.
•Bidirectional—Leave checked for this circuit.
•Number of Circuits—Type the number of high-order circuits you want to create. The default is 1.
•Auto-ranged—Applies to automatically-routed circuits only. If you entered more than 1 in Number of Circuits, uncheck this check box. (The check box is unavailable if only one circuit is entered in Number of Circuits.)
•State—Choose a service state to apply to the circuit:
–IS—The circuit is in service.
–OOS—The circuit is out of service. Traffic is not passed on the circuit.
–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
–OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
•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 will apply 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 will not change the state of the source and destination ports.
Note Loss of Signal alarms appear if in service (IS) ports are not receiving signals.
•Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•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 5 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task.
Step 6 Click Next.
Step 7 Complete the "DLP-D97 Provision a High-Order Circuit Source and Destination" task for the high-order circuit you are creating.
Step 8 In the Circuit Routing Preferences area (Figure 8-11), uncheck Route Automatically.

•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 10.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 12.
•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 12.
Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.
Step 10 If you selected Fully Protected Path, 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 may be node-diverse, but CTC does not check for node diversity.
Step 11 If you selected Fully Protected Path and the circuit will be routed on an SNCP dual ring interconnect (DRI), click the Dual Ring Interconnect check box.
Step 12 Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually.
Step 13 Complete the "DLP-D98 Provision a High-Order Circuit Route" task.
Step 14 Click Finish. If the path does not meet the specified path diversity requirement, CTC shows an error message and allows you to change the circuit path. If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears after the circuit is created so you can create the remaining circuits. Repeat Steps 4 through 14 for each additional circuit.
Step 15 When all the circuits are created, the main Circuits window appears. Verify that the circuit(s) you created appear in the window.

Step 7 Click Next.
Step 8 Complete the "DLP-D97 Provision a High-Order Circuit Source and Destination" task for the circuit you are creating.
Step 9 Uncheck Route Automatically. When Route Automatically is not selected, Using Required Nodes/Spans and Review Route Before Circuit Creation are unavailable.
Step 10 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 11. Fully-protected paths may or may 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 13.
•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 13.
Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.
Step 11 If you selected Fully Protected Path, 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 may 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 12 If you selected Fully Protected Path and the circuit will be routed on an SNCP dual ring interconnect (DRI), click the Dual Ring Interconnect check box.
Step 13 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.

–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
–OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
•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 will apply 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 will not change the state of the source and destination ports.
Note Loss of Signal alarms appear if in service (IS) ports are not receiving signals.
•Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•Protected Drops—Uncheck this check box if it is selected.

Note In this procedure, cross-connect refers to a circuit connection created within the same node between the Ethernet card and an STM-N card connected to third-party equipment. You create cross-connects at the source and destination nodes so an Ethernet circuit can be routed from source to destination across third-party equipment.
Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23 at a circuit endpoint. If you are already logged in, continue with Step 3.
Step 2 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. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 3.
Step 3 Complete the "DLP-D99 Determine Available VLANs" task to verify that sufficient VLAN capacity is available (you will create a VLAN during each circuit creation task).
Step 4 Verify that the Ethernet card that will carry the circuit is provisioned for Multicard EtherSwitch Group. See the "DLP-D246 Provision E-Series Ethernet Card Mode" task.
Step 5 Provision and enable the Ethernet ports. See "DLP-D220 Provision E-Series Ethernet Ports" task.
Step 6 From the View menu, choose Go to Network View.
Step 7 Click the Circuits tab and click Create.
Step 8 In the Create Circuits dialog box, complete the following fields:
•Name—Assign a name to the source cross-connect. 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 source cross-connect.
•Type—Choose VC_HO_PATH_CIRCUIT.
•Size—Choose the size of the circuit that will be carried by the cross-connect. For Multicard EtherSwitch circuits, the available sizes are VC4 and VC4-2c.
•Bidirectional—Leave the default unchanged (checked).
•Number of Circuits—Leave the default unchanged (1).
•Auto-ranged—Unavailable.
•State—Choose a service state to apply to the circuit:
–IS—The circuit is in service.
–OOS—The circuit is out of service. Traffic is not passed on the circuit.
–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).
–OOS-MT—The circuit is in a maintenance 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 state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-11.
