Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
This chapter explains how to create Cisco ONS 15327 electrical circuits, VT tunnels, optical circuits, and Ethernet circuits. For additional information about ONS 15327 circuits, refer to the Circuits and Tunnels chapter in the Cisco ONS 15327 Reference Manual.

Table 5-1 defines ONS 15327 circuit creation terms and options.
Table 5-1 ONS 15327 Circuit Options
|
Circuit Option
|
Description
|
Source |
The circuit source is where the circuit enters the ONS 15327 network. |
Destination |
The circuit destination is where the circuit exits an ONS 15327 network. |
Automatic circuit routing |
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 STS or VT for each circuit segment and create circuits from work orders prepared by an operations support system (OSS) like the Telcordia TIRKS system. |
VT tunnel |
VT tunnels allow VT1.5 circuits to pass through an ONS 15327 without utilizing cross-connect resources. VT circuits using VT tunnels will use cross-connect capacity only at the source and destination nodes. One VT tunnel can carry 28 VT1.5 circuits. |
VT Aggregation Point |
VT aggregation points (VAPs) allow VT circuits to be aggregated into an STS to reduce VT matrix resource utilization. The STS grooming end of the VAP requires an OC-N card. |
ONS 15327 circuits are either VT or STS circuits. Table 5-2 shows the circuit source and destination options for VT circuits.

Step 1 Complete the "DLP-B60 Log into CTC" task at an ONS 15327 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 15327 network, the node icons will be stacked on the left side of the graphic area, possibly out of view. Use the scroll bar below the network map to display the icons. To separate the icons press Ctrl and drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.
Step 3 Verify node accessibility. In the network view, all node icons must be either green, yellow, orange, or red.
If all network nodes do not appear after a few minutes, or if a node icon is gray with an IP address under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box on the CTC Login dialog box. If problems persist, see "Turn Up Network" to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15327 Troubleshooting Guide for troubleshooting procedures.
Step 4 Verify DCC connectivity. All nodes must be connected by green lines. If lines are missing or gray in color, do not continue. See "Turn Up Network" and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing.
Step 5 Investigate and resolve, if necessary, all critical (red node icon) or major (orange node icon) alarms. Click the Alarms tab to view alarm descriptions. Refer to the Cisco ONS 15327 Troubleshooting Guide to resolve alarms before continuing.
Step 6 From the View menu choose Go to Home View. Verify that the node is provisioned according to your site or engineering plan:
a. View the cards on the shelf map. Verify that the ONS 15327 cards appear in the specified slots.
b. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and NTP/SNTP server IP address (if used) are correctly provisioned. If needed, make corrections using the"81 Change Node Management Information" procedure.
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 "201 Change CTC Network Access" procedure.
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 "170 Create Optical Protection Groups" procedure.
e. If the node is in a BLSR, click the BLSR tab. (If the node is not in a BLSR, continue with Step f.) Verify that the following items are provisioned as specified in your site plan:
–BLSR type (2-Fiber)
–BLSR ring ID and node IDs
–Ring reversion time
–East and west card assignments
If you need to make corrections, see the "40 Provision BLSR Nodes" procedure for instructions.
f. Click the Security tab. Verify that the users and access levels are provisioned as specified. If not, see the "30 Create Users and Assign Security" procedure to correct the information.
g. If SNMP is used, click the SNMP tab and verify the trap and destination information. If the information is correct, see the "87 Change SNMP Settings" procedure to correct the information.
h. Click the SONET DCC tab. Verify that SDCC(s) were created to the applicable OC-N slots and ports. If DCCs were not created for the appropriate OC-N slots and ports, see "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 "85 Change Node Timing" procedure 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 "70 Create, Download, and Assign Alarm Severity Profiles" procedure 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 5-1.
Stop. You have completed this procedure.
NTP-B181 Create an Automatically Routed DS-1 Circuit

Step 1 Complete the "DLP-B60 Log into CTC" task at a node on the network where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-B314 Assign a Name to a Port" task. 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 (Figure 5-1), 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 VT. VT cross-connects will carry the DS-1 circuit across the ONS 15327 network.
•Size—VT1.5 is the default. You cannot change it.
•Bidirectional—Leave checked for this circuit.
•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 sequential 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 this check 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 permits loopbacks 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-B230 Change a Circuit State" task.
Note If VT circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, VT circuits in OOS_AINS will change to IS even if a physical signal is not present. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Apply to drop ports—Check this check box 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 port. If not, a Warning dialog box displays the ports where the circuit state could not be applied. If the check box is unchecked, CTC will not change the state of the source and destination ports.
Note LOS alarms are generated if in service (IS) ports are not receiving signals.
•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. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•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—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards and ports as source and destination choices.
Figure 5-1 Setting Circuit Attributes For a DS-1 Circuit
Step 6 If the circuit will be routed on a path protection, complete the "DLP-B218 Provision Path Protection Selectors During Circuit Creation" task. Otherwise, continue with the next step.
Step 7 Click Next.
Step 8 Complete the "DLP-B95 Provision a DS-1 Circuit Source and Destination" task.
Step 9 In the Circuit Routing Preferences area (Figure 5-2), click 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.
•Review Route Before Creation—Check this check box if you want 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 path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 13.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes on the Warning dialog box, and then continue with Step 13.
Caution
Circuits routed on BLSR protection channels are not protected. They are preempted during BLSR switches.
Step 11 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 path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths may be node-diverse, but CTC does not check for node diversity.
Figure 5-2 Setting Circuit Routing Preferences for a DS-1 Circuit
Step 12 If you selected Fully Protected Path and the circuit will be routed on a path protection dual ring interconnect (DRI), check the Dual Ring Interconnect check box.
Step 13 If you selected Using Required Nodes/Spans in Step 9, complete the following substeps. If not, continue with Step 16.
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 14 Click Next. On the VT Circuit panel in the Create area, choose one of the following:
•VT Tunnel on Transit Nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15327s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15327 Reference Manual for more information.
•VT Aggregation Point—This option is available if you are creating a DS-1 circuit to an OC-N port. A VT aggregation point (VAP) allows VT1.5 circuits to be routed through a node using one STS connection on the cross-connect card matrix rather than multiple connections on the VT1.5 matrix. If available, choose one of the following:
–Use source as the STS grooming end—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an OC-N card.
–Use destination as the STS grooming end—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This will be the only available option if CTC cannot create a VT tunnel or VAP.
Step 15 If you chose VT Aggregation Point, complete the following substeps. If not, continue with Step 16.
a. Click Next.
b. On the VT Aggregation Point Destination panel, click the node that you want to be the VAP destination, then click Add Destination.
Step 16 If you selected Review Route Before Creation in Step 9, complete the following substeps. If not, continue with Step 17.
a. Click Next.
b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "182 Create a Manually Routed DS-1 Circuit" procedure.
Step 17 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 for you to create the remaining circuits. Repeat this procedure for each additional circuit.
•After completing the circuit(s), CTC displays the Circuits window.
Step 18 On the Circuits window, verify that the new circuit(s) appear in the circuits list.
Step 19 Complete the "135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 1 Complete the "DLP-B60 Log into CTC" task at a node on the network where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-B314 Assign a Name to a Port" task. If not, continue with Step 3. CTC will assign a circuit name automatically based on circuit type, node name, and sequence number.
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 (see Figure 5-1), 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 VT. VT cross-connects will carry the DS-1 circuit across the ONS 15327 network.
•Size—VT1.5 is the default. You cannot change it.
•Bidirectional—Leave checked for this circuit.
•Number of circuits—Type the number of DS-1 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 permits loopbacks 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-B230 Change a Circuit State" task.
Note If VT circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, VT circuits in OOS_AINS will change to IS even if a physical signal is not present. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Apply to drop ports—Check this check box if you want to apply the 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 port. If not, a Warning dialog box displays the ports where the circuit state could not be applied. If the check box is unchecked, CTC will not change the state of the source and destination ports.
Note LOS alarms appear if in service (IS) ports are not receiving signals.
•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. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•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—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected cards and ports as source and destination choices.
Step 6 If the circuit will be routed on a path protection, complete the "DLP-B218 Provision Path Protection Selectors During Circuit Creation" task. Otherwise, continue with the next step.
Step 7 Click Next.
Step 8 Complete the "DLP-B95 Provision a DS-1 Circuit Source and Destination" task.
Step 9 In the Circuit Routing Preferences area (see Figure 5-2), uncheck Route Automatically.
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 path protection segments (with primary and alternate paths), and the path diversity options apply only to path protection segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes on the Warning dialog box, and then continue with Step 15.
Caution
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 11 If you selected Fully Protected Path, choose a Node-Diverse Path option:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths 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 a path protection dual ring interconnect (DRI), check the Dual Ring Interconnect check box.
Step 13 Click Next. On the VT Circuit panel in the Create area, choose one of the following:
•VT Tunnel on Transit Nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15327s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15327 Reference Manual for more information.
•VT Aggregation Point—This option is available if you are creating a DS-1 circuit to an OC-N port. A VT aggregation point (VAP) allows VT1.5 circuits to be routed through a node using one STS connection on the cross-connect card matrix rather than multiple connections on the VT1.5 matrix. If available, choose one of the following:
–Use source as the STS grooming end—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an OC-N card.
–Use destination as the STS grooming end—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This will be the only available option if CTC cannot create a VT tunnel or VAP.
Step 14 If you chose VT Aggregation Point, complete the following substeps. If not, continue with Step 16.
a. Click Next.
b. On the VT Aggregation Point Destination panel, click the node that you want to be the VAP destination, then click Add Destination.
Step 15 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 1 Complete the "DLP-B60 Log into CTC" taskat a node on the network where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-B314 Assign a Name to a Port" task. 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 (Figure 5-3), 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 VT.
•Size—VT1.5 is the default. You cannot change it.
•Bidirectional—Uncheck for this circuit.
•Number of circuits—Leave the default unchanged (1).
•Auto-ranged—Unavailable when the Number of Circuits field is 1.
•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 permits loopbacks 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-B230 Change a Circuit State" task.
Note If VT circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, VT circuits in OOS_AINS will change to IS even if a physical signal is not present. Refer to the Cisco ONS 15327 Reference Manual for more information.
•Apply to drop ports—Check this check box if you want to apply the 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 port. If not, a Warning dialog box displays the ports where the circuit state could not be applied. If the check box is unchecked, CTC will not change the state of the source and destination ports.
Note LOS alarms appear if in service (IS) ports are not receiving signals.
•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. If this check box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•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—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays only protected ports as source and destination choices.

Step 6 Click Next.
Step 7 Complete the "DLP-B95 Provision a DS-1 Circuit Source and Destination" task.
Step 8 In the Circuit Routing Preferences area, uncheck Route Automatically. When Route Automatically is not selected, Using Required Nodes/Spans and Review Route Before Circuit Creation are unavailable.
Step 9 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 path protection segments (with primary and alternate paths), and the path diversity options apply only to path protection segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes on the Warning dialog box, and then continue with Step 15.
Caution
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 10 If you selected Fully Protected Path, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths 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 a path protection dual ring interconnect (DRI), check the Dual Ring Interconnect check box.
Step 12 Click Next. On the VT Circuit panel in the Create area, choose one of the following:
•VT Tunnel on Transit Nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15327s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15327 Reference Manual for more information.
•VT Aggregation Point—This option is available if you are creating a DS-1 circuit OC-N port. A VT aggregation point (VAP) allows VT1.5 circuits to be routed through a node using one STS connection on the cross-connect card matrix rather than multiple connections on the VT1.5 matrix. If available, choose one of the following:
–Use source as the STS grooming end—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an OC-N card.
–Use destination as the STS grooming end—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This will be the only available option if CTC cannot create a VT tunnel or VAP.
Step 13 If you chose VT Aggregation Point, complete the following substeps. If not, continue with Step 16.
a. Click Next.
b. On the VT Aggregation Point Destination panel, click the node that you want to be the VAP destination, then click Add Destination.
Step 14 Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.
Step 15 Complete the "DLP-B96 Provision a DS-1 or DS-3 Circuit Route" task for the DS-1 circuit you are creating.
Step 16 Click Finish. CTC completes the circuit and displays the Circuits window.
Step 17 On the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and Search buttons become active.
Step 18 Click Edit (or double-click the circuit row). The Edit Circuit window appears with the General tab selected.
All nodes in the DCC network appear on the network map. Circuit source and destination information appears under the source and destination nodes. To display a detailed view of the circuit, click Show Detailed Map. To rearrange a node icon, select the node, press Ctrl, then drag and drop the icon to the new location.
Step 19 On the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 20 Click Create.
Step 21 On the Define New Drop dialog box, create the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the target card and slot.
c. Port, STS, VT, or DS1—Choose the port, STS, VT, or DS1 from the Port, STS, VT or DS1 drop-down menus. The card selected in Step b determines the fields that appear. See Table 5-2 for a list of options.
d. The routing preferences for the new drop will match those of the original circuit. However, you can modify the following:
–If the original circuit was routed on a protected path, you can change the nodal diversity options: [Required, Desired, Don't Care; Link Diverse only]. See Step 10 for options descriptions.
–If the original circuit was not routed on a protected path, the Protection Channel Access options is available. See Step 9 for a description of the PCA option.
e. Click OK. The new drop appears in the Drops list.
Step 22 If you need to create additional drops for the circuit, repeat Steps 20 and 21 to create the additional drops.
Step 23 Choose Close. The Circuits window appears.
Step 24 Verify that the new drops appear in the Destination column for the circuit you edited. If they do not appear repeat Steps 5 through 22, making sure all options are provisioned correctly.
Step 25 Complete the "135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.

•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 path protection segments (with primary and alternate paths), and the path diversity options apply only to path protection segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 13.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes on the Warning dialog box, and then continue with Step 13.
Caution
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR 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 path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths 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 a path protection dual ring interconnect (DRI), check the Dual Ring Interconnect check box.
Step 13 Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.
Step 14 Complete the "DLP-B96 Provision a DS-1 or DS-3 Circuit Route" task for the DS-3 you are creating.
Step 15 Click Finish. After completing the circuit, CTC displays the Circuits window.
Step 16 On the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and Search radio buttons become active.

Circuit source and destination information appears under the source and destination nodes. To display a detailed view of the circuit, click Show Detailed Map. You can rearrange the node icons by selecting the node with the left mouse button while simultaneously pressing Ctrl, then dragging the icon to the new location.
Step 18 On the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 19 Click Create.
Step 20 On the Define New Drop dialog box, define the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the target card and slot
c. Port, STS—Choose the port and/or STS from the Port and STS drop-down menus. The card selected in Step b determines whether port, STS, or both display. See Table 5-2 for a list of options.
d. The routing preferences for the new drop will match those of the original circuit. However, you can modify the following:
–If the original circuit was routed on a protected path, you can change the nodal diversity options: [Required, Desired, Don't Care; Link Diverse only]. See Step 11 for options descriptions.
–If the original circuit was not routed on a protected path, the Protection Channel Access options is available. See Step 10 for a description of the PCA option.
e. Click OK. The new drop appears in the Drops list.
Step 21 If you need to create additional drops for the circuit, repeat Steps 19 and 20 to create the additional drops.
Step 22 Click Close. The Circuits window displays.
Step 23 Verify that the new drops appear in the Destination column for the circuit you edited. If they do not appear, repeat this procedure, making sure all options are provisioned correctly.
Step 24 Complete the "135 Test Electrical 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 path protection selectors:
•Revertive—Check this check 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 STS circuits, set the path protection path-level signal failure bit error rate (BER) thresholds. Unavailable for VT circuits.
•SD threshold—For STS circuits, set the path protection path-level signal degrade BER thresholds. Unavailable for VT circuits.
•Switch on PDI-P—For STS circuits, check this check box if you want traffic to switch when an STS payload defect indicator is received. Unavailable for VT circuits.
Step 2 Return to your originating procedure (NTP).
DLP-B208 Provision a DS-3 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 XTC card where the circuit will originate
Step 3 From the Port drop-down menu choose the source XTC card as appropriate.
Step 4 If you need to create a secondary source, for example, a path protection bridge/selector circuit entry point in a multivendor path protection, click Use Secondary Source and repeat Steps 1 through 3 to define the secondary source. If you do not need to create a secondary source, continue with Step 5.
Step 5 Click Next.
Step 6 From the Node drop-down menu choose the destination (termination) node.
Step 7 From the Slot drop-down menu choose the slot containing the destination card. The destination is typically a XTC card. You can also choose an OC-N card to the map DS-3 circuit to an STS.
Step 8 Depending on the destination card, choose the destination port or STS from the sub-menus that display based on the card selected in Step 3. See Table 5-2 for a list of valid options. CTC does not display ports, STSs, VTs, or DS1s if they are already in use by other circuits. If you and a user working on the same network choose the same port, STS, VT, port, or DS1 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 9 If you need to create a secondary destination, for example, a path protection bridge/selector circuit exit point in a multivendor path protection, click Use Secondary Destination and repeat Steps 6 and 7 to define the secondary destination.
Step 10 Click Next.

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 5-10), 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 STS.
•Size—Choose the optical circuit size: STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, STS-48c.
•Bidirectional—Leave checked for this circuit.
•Number of circuits—Type the number of optical 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 checked when you enter more than 1 in the Number of circuits field. Leave checked if you are creating multiple optical circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck this check box if you do not want CTC to create the circuits automatically.
•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 permits loopbacks 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-B230 Change a Circuit State" task.
•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 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 port. If not, a Warning dialog box displays the ports where the circuit state could not be applied. If the check box is unchecked, CTC will not change the state of the source and destination ports.
Note LOS alarms appear if in service (IS) ports are not receiving signals.
•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.

Step 8 Complete the "DLP-B97 Provision an Optical Circuit Source and Destination" task for the optical circuit you are creating.
Step 9 In the Circuit Routing Preferences area (Figure 5-11), 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.
•Review Route Before Creation—Check 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 path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 13.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes on the Warning dialog box, and 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 path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths may be node-diverse, but CTC does not check for node diversity.

DLP-B97 Provision an Optical Circuit Source and Destination
Step 1 From the Node drop-down menu choose the node where the circuit will originate.
Step 2 From the Slot drop-down menu choose the slot containing the optical card where the circuit originates. (If a card's capacity is fully utilized, it does not appear in the menu.)
Step 3 Depending on the circuit origination card, choose the source port and/or STS from the Port and STS sub-menus. The Port menu is only available if the card has multiple ports. STSs are not displayed if they are already in use by other circuits.
Note The STSs that display depend on the card, circuit size, and protection scheme. For example, if you create an STS-3c circuit on an OC-12 card in a path protection, only four STSs are available. If you create an STS-3c circuit on an OC-12 card in a BLSR, two STSs are available because of the BLSR protection characteristics.
Step 4 If you need to create a secondary source, for example, a path protection bridge/selector circuit entry point in a multivendor path protection, click Use Secondary Source and repeat Steps 1 through 3 to define the secondary source.
Step 5 Click Next.
Step 6 From the Node drop-down menu choose the destination node.
Step 7 From the Slot drop-down menu choose the slot containing the optical card where the circuit will terminate (destination card). (If a card's capacity is fully utilized, the card does not appear in the menu.)
Step 8 Depending on the card selected in Step 2, choose the destination port and/or STS from the Port and STS sub-menus. The Port menu is available only if the card has multiple ports. The STSs that display depend on the card, circuit size, and protection scheme.
Step 9 If you need to create a secondary destination, for example, a path protection bridge/selector circuit entry point in a multivendor path protection, click Use Secondary Destination and repeat Steps 6 through 8 to define the secondary destination.
Step 10 Click Next.
Step 11 Return to your originating procedure (NTP).
DLP-B98 Provision an Optical 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 display span information. The source STS appears. Figure 5-12 shows an example.
Figure 5-12 Manually Routing an OC-N Circuit
Step 3 If you want to change the source STS, adjust the Source STS field; otherwise, continue with the next step.
Note VT is gray for OC-N circuits.
Step 4 Click Add Span.The span is added to the Included Spans list and the span arrow turns blue.
Step 5 Repeat Steps 2 through 4 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 path protection or unprotected portions of the circuit route from the source to the destination
•Add one span for all BLSR or 1+1 portions of route from the source to the destination
Suppose you want to create a fully protected circuit from a path protection node subtended from the BLSR. For example, a BLSR is comprised of Node 1, Node 2, and Node 3, and a path protection subtends from Node 3 to Node 4. To create a circuit from Node 4 to Node 1, you include two spans in the circuit route from Node 4 to Node 3, since both the working and protect path must be provisioned for the path protection portion of the circuit, and you provision one circuit span from Node 3 to Node 1, since the BLSR provides protection.
Step 6 Return to your originating procedure (NTP).

Step 18 If you are building a single-card EtherSwitch circuit and want to disable spanning tree protection on this circuit, uncheck the Enable Spanning Tree check box and click OK on the Disabling Spanning Tree dialog box. The Enable Spanning Tree check box will remain checked or unchecked for the creation of the next single-card point-to-point Ethernet circuits.
Caution
Disabling spanning tree protection increases the likelihood of logic loops on an Ethernet network.
Caution
Turning off spanning tree on a circuit-by-circuit basis means that the ONS 15327 is no longer protecting the Ethernet circuit and that the circuit must be protected by another mechanism in the Ethernet network.
Caution
Multiple circuits with spanning tree protection enabled will incur blocking if the circuits traverse the same E-series card and use the same VLAN.
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.

A port marked with this symbol does not belong to the VLAN. |
Untag |
The ONS 15327 will tag ingress frames and strip tags from egress frames. |
Tagged |
The ONS 15327 will process ingress frames according to the VLAN ID; egress frames will not have their tags removed. |
b. If a port is a member of only one VLAN, choose Untag from the Port column in the VLAN's row. Choose -- for all the other VLAN rows in that Port column.
Note The VLAN with Untag selected can connect to the port, but other VLANs cannot access that port.
c. Choose Tagged at all VLAN rows that need to be trunked. Choose Untag VLAN rows that do not need to be trunked, for example, the default VLAN.
Note Each Ethernet port must attach to at least one untagged VLAN. A trunk port connects multiple VLANs to an external device, such as a switch, which also supports trunking. A trunk port must have tagging (802.1Q) enabled for all the VLANs that connect to that external device.
