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 15454 electrical circuits, tunnels, optical circuits, Ethernet circuits, and virtual concatenated (VCAT) circuits. For additional information about ONS 15454 circuits, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.

Table 6-1 defines ONS 15454 circuit creation terms and options.

Table 6-1: ONS 15454 Circuit Options
Circuit Option Description

Source

The circuit source is where the circuit enters the ONS 15454 network.

Destination

The circuit destination is where the circuit exits an ONS 15454 network.

Automatic circuit routing

Cisco Transport Controller (CTC) routes the circuit automatically on the shortest available path based on routing parameters and bandwidth availability.

Manual circuit routing

Manual routing allows you to choose a specific path, not just the shortest path chosen by automatic routing. You can choose a specific synchronous transport signal (STS) or Virtual Tributary (VT) for each circuit segment and create circuits from work orders prepared by an operations support system (OSS) like the Telcordia Trunk Information Record Keeping System (TIRKS).

VT tunnel

VT tunnels allow VT1.5 circuits to pass through an ONS 15454 without utilizing cross-connect card (XC, XCVT, XC10G, XC-VXC-10G) resources. VT circuits using VT tunnels use cross-connect capacity only at the source and destination nodes. One VT tunnel can carry 28 VT1.5 circuits or 21 VT2 circuits.

VT aggregation point

VT aggregation points (VAPs) allow VT circuits to be aggregated into an STS for handoff to non-ONS 15454 networks or equipment, such as interoffice facilities (IOFs), switches, or digital access and cross-connect systems (DACS). VAPs reduce VT matrix resource utilization at the node where the VTs are aggregated onto the STS. This node is called the STS grooming end. The STS grooming end requires an EC1, DS3, DS3E, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card. VAPs can be created on BLSR, 1+1, or unprotected nodes, but cannot be created on path protection nodes.

ONS 15454 circuits are either VT or STS circuits. Table 6-2 shows the circuit source and destination options for VT circuits.

  1. Complete the "DLP-A60 Log into CTC" task. If you are already logged in, continue with Step 2.
  2. From the View menu, choose Go to Network View. Wait for all the nodes that are part of the network to appear on the network map. (Large networks might take several minutes to display all the nodes.)
    Note: If this is the first time your computer has connected to this ONS 15454 network, the node icons are stacked on the left side of the graphic area, possibly out of view. Use the scroll bar under the network map to display the icons. To separate the icons, drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.
  3. Verify node accessibility. In network view, all node icons must be either green, yellow, orange, or red.
    If all network nodes do not appear after a few minutes, or if a node icon is gray with "Unknown" under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see Turn Up a Network to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15454 Troubleshooting Guide for troubleshooting procedures.
  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 a Network and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing.
  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 Troubleshooting Guide to resolve alarms before continuing.
  6. From the View menu, choose Go to Home View. Verify that the node is provisioned according to your site or engineering plan:
    1. View the cards in the shelf map. Verify that the ONS 15454 cards appear in the specified slots.
    2. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and Network Time Protocol/Simple Network Time Protocol (NTP/SNTP) server IP address (if used) are correctly provisioned. If needed, make corrections using the NTP-A25 Set Up Name, Date, Time, and Contact Information.
    3. 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-A169 Set Up CTC Network Access.
    4. 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-A324 Create Protection Groups.
    5. 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 or 4-fiber)
      • BLSR ring ID and node IDs
      • Ring reversion time
      • East and west card assignments
      • 4-fiber BLSRs: Span reversion and east/west protect card assignments
      If you need to make corrections, see the NTP-A40 Provision BLSR Nodes for instructions.
    6. Click the Security tab. Verify that the users and access levels are provisioned as specified. If not, see the NTP-A30 Create Users and Assign Security to correct the information.
    7. If Simple Network Management Protocol (SNMP) is used, click the SNMP tab and verify the trap and destination information. If the information is not correct, see the NTP-A87 Change SNMP Settings to correct the information.
    8. Click the Comm Channels tab. Verify that DCCs were created to the applicable OC-N slots and ports (time-division multiplexing [TDM] nodes) or optical service channel (OSC) slots and ports (dense wavelength division multiplexing [DWDM] nodes). If DCCs were not created for the appropriate OC-N or OSC slots and ports, see Turn Up a Network and complete the turn-up procedure appropriate for your network topology. To provision OSC ports, refer to the Cisco ONS 15454 DWDM Procedure Guide
    9. Click the Timing tab. Verify that timing is provisioned as specified. If not, use the NTP-A85 Change Node Timing to make the changes.
    10. Click the Alarm Profiles tab. If you provisioned optional alarm profiles, verify that the alarms are provisioned as specified. If not, see the NTP-A71 Create, Download, and Assign Alarm Severity Profiles to change the information.
    11. Verify that the network element (NE) defaults listed in the status area of the node view window are correct.
  7. Repeat Step 6 for each node in the network.
  8. Complete the appropriate circuit creation procedure from the NTP list in the Before You Begin.
    Stop. You have completed this procedure.

NTP-A181 Create an Automatically Routed DS-1 Circuit

Purpose

This procedure creates an automatically routed DS-1 circuit, meaning that CTC chooses the circuit route based on the parameters you specify and on the software version.

Note: This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the "Network Element Defaults" appendix in the Cisco ONS 15454 Reference Manual.

  1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the circuit. If you are already logged in, continue with Step 2.
  2. If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
  3. From the View menu, choose Go to Network View.
  4. Click the Circuits tab, then click Create.
  5. In the Circuit Creation dialog box, complete the following fields:
    • Circuit Type-Choose VT or STS. VT cross-connects will carry the DS-1 circuit across the ONS 15454 network.
    • Number of Circuits-Enter the number of DS-1 circuits that 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 the box if you do not want CTC to create sequential circuits automatically.
  6. Click Next.
  7. Define the circuit attributes (Figure 6-1):
    • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
    • Size-If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.
    • Bidirectional-Leave checked for this circuit (default).
    • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.
    • Diagnostic-Leave unchecked.
    • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
      • IS-Puts the circuit cross-connects in the In-Service and Normal (IS-NR) service state.
      • OOS,DSBLD-Puts the circuit cross-connects in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD) service state. Traffic is not passed on the circuit.
      • IS,AINS-Puts the circuit cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS) service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
      • OOS,MT-Puts the circuit cross-connects in the Out-of-Service and Management, Maintenance (OOS-MA,MT) service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
      For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
    • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
  • Protected Drops-Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC displays only protected cards and ports as source and destination choices.

  1. If the circuit will be routed on a path protection configuration, complete the "DLP-A218 Provision Path Protection Selectors" task. Otherwise, continue with the next step.
  2. Click Next.
  3. Complete the "DLP-A95 Provision a DS-1 Circuit Source and Destination" task.
  4. In the Circuit Routing Preferences area (Figure 6-2), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.
  • Using Required Nodes/Spans-Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
  • Review Route Before Creation-Check this check box if you want to review and edit the circuit route before the circuit is created.
Figure 6-2: Setting Circuit Routing Preferences for a DS-1 Circuit

124042.jpg

  1. To set the circuit path protection, complete one of the following:
    • To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
    • To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
    • To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.

    Caution! Circuits routed on BLSR protection channels are not protected. They are preempted during BLSR switches.

  2. If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:
    • Nodal Diversity Required-Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
    • Nodal Diversity Desired-Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
    • Link Diversity Only-Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
  3. If you selected Fully Protected Path in Step 12 and the circuit will be routed on a BLSR or path protection dual-ring interconnect (DRI), check the Dual Ring Interconnect check box.
  4. If you checked Using Required Nodes/Spans in Step 11 or Dual Ring Interconnect for a path protection configuration in Step 14, complete the following substeps. If you checked Dual Ring Interconnect for a BLSR, skip this step and continue with Step 16. If you did not select any of these options, continue with Step 17.
    1. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.
    2. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.
    3. Repeat Substep 2 for each node or span you wish to include or exclude.
    4. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
  5. Complete the "DLP-A563 Configure an Automatically Routed BLSR DRI" task.
  6. Click Next. If you are creating VT circuits, in the Create area of the VT Matrix Optimization page choose one of the following options. If not, continue with Step 18.
    • Create VT tunnel on transit nodes-This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s 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 15454 Reference Manual for more information.
    • Create VT aggregation point-This option is available if the DS-1 circuit source or destination is on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:
      • STS grooming node is source node, VT grooming node is destination node-Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.
      • STS grooming node is destination node, VT grooming node is source node-Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.
    • None-Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
  7. If you selected Review Route Before Creation in Step 11, complete the following substeps. If not, continue with Step 19.
    1. Click Next.
    2. 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.
    3. 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 NTP-A182 Create a Manually Routed DS-1 Circuit.
  8. Click Finish. One of the following results occurs if you entered more than one circuit in the Number of Circuits field on the Circuit Creation dialog box.
    • If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.
    • If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.
  9. In the Circuits window, verify that the new circuits appear in the circuits list.
  10. Complete the NTP-A135 Test Electrical Circuits. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

  1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the circuit. If you are already logged in, continue with Step 2.
  2. If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
  3. From the View menu, choose Go to Network View.
  4. Click the Circuits tab, then click Create.
  5. In the Circuit Creation dialog box, complete the following fields:
    • Circuit Type-Choose VT or STS. VT cross-connects will carry the DS-1 circuit across the ONS 15454 network.
    • Number of Circuits-Enter the number of DS-1 circuits that you want to create. The default is 1.
    • Auto-ranged-(Automatically routed circuits only) If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, uncheck this box. (The box is unavailable if only one circuit is entered in the Number of Circuits field.)
  6. Click Next.
  7. Define the circuit attributes (Figure 6-2):
    • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
    • Size-If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.
    • Bidirectional-Leave checked for this circuit (default).
    • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.
    • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
      • IS-Puts the circuit cross-connects in the IS-NR service state.
      • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
      • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
      • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
      For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
    • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
    Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
    • Protected Drops-Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC shows only protected cards and ports as source and destination choices.
  8. If the circuit will be routed on a path protection configuration, complete the "DLP-A218 Provision Path Protection Selectors" task. Otherwise, continue with the next step.
  9. Click Next.
  10. Complete the "DLP-A95 Provision a DS-1 Circuit Source and Destination" task.
  11. In the Circuit Routing Preferences area (Figure 6-2), uncheck Route Automatically.
  12. To set the circuit path protection, complete one of the following:
    • To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
    • To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
    • To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 16.

Caution! Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

  1. If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose a Node-Diverse Path option:
    • Nodal Diversity Required-Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
    • Nodal Diversity Desired- Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
    • Link Diversity Only-Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
  2. If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI or BLSR DRI, check the Dual Ring Interconnect check box.
  3. Click Next. In the Create area of the VT Matrix Optimization page, choose one of the following:
    • Create VT tunnel on transit nodes-This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s 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 15454 Reference Manual for more information.
    • Create VT aggregation point-This option is available if the DS-1 circuit source or destination is on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:
    • STS grooming node is source node, VT grooming node is destination node-Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC1, DS3, DS3E, DS3i-N-12, DS3XM-6, DS3XM-12, or OC-N card.
    • STS grooming node is destination node, VT grooming node is source node-Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC1, DS3, DS3E, DS3i-N-12, DS3XM-6, DS3XM-12, or OC-N card.
    • None-Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
  4. Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If you checked Dual Ring Interconnect for BLSR, continue with Step 17. If not, continue with Step 16.
  5. Complete the "DLP-A564 Configure a Manually Routed BLSR DRI" task.
  6. Complete the "DLP-A96 Provision a DS-1 or DS-3 Circuit Route" task for the DS-1 circuit you are creating.
  7. Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 13. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.
  8. If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 19 for each additional circuit.
  9. When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.
  10. Complete the NTP-A135 Test Electrical Circuits. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

NTP-A184 Create an Automatically Routed DS-3 or EC-1 Circuit

Purpose

This procedure creates an automatically routed DS-3 or EC-1 circuit and also gives you the option of creating a circuit over a pair of portless transmultiplexing interfaces. CTC routes the circuit automatically based on circuit creation parameters and the software version.

Tools/Equipment

For portless transmultiplexing configurations, a DS3XM-12 must be installed on a node through which the circuit will be routed.

For VT2 circuits, the following cards must be installed at the circuit source and destination nodes: XC-VXC-10G and EC1.

For a full description of these defaults see the "Network Element Defaults" appendix in the Cisco ONS 15454 Reference Manual.

  1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the circuit. If you are already logged in, continue with Step 2.
  2. If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
  3. From the View menu, choose Go to Network View.
  4. Click the Circuits tab, then click Create.
  5. In the Circuit Creation dialog box, complete the following fields:
    • Circuit Type-Choose VT or STS. STS cross-connects will carry the DS-3 or EC-1 circuit across the ONS 15454 network.
    • Number of Circuits-Enter the number of DS-3 or EC-1 circuits that you want to create. The default is 1. If you are creating multiple circuits with sequential source and destination ports, you can use Auto-ranged to create the circuits automatically.
    • Auto-ranged-This box is automatically selected if you enter more than 1 in the Number of Circuits field. Leave selected if you are creating multiple DS-3 or EC-1 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 sequential circuits automatically.
  6. Click Next.
  7. Define the circuit attributes (Figure 6-4):
    • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
    • Size-For circuits on the DS3i-N-12 card, choose STS-3c. This sets a port group for Ports 1, 4, 7, and 10 using three ports at any given time. For VT2 circuits on the EC1 card, choose VT2. For all other circuits, choose STS-1.
    • Bidirectional-Leave checked for this circuit (default).
    • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.
    • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
      • IS-Puts the circuit cross-connects in the IS-NR service state.
      • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
      • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
      • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
      For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
    • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
  • Protected Drops-Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC provides only protected cards and ports as source and destination choices.

    • Using Required Nodes/Spans-Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.
    Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
    • Review Route Before Creation-Check this check box to review and edit the circuit route before the circuit is created.
    • VT-DS3 Mapped Conversion-Check this check box to create a circuit using the portless transmultiplexing interface of the DS3XM-12 card.

    124045.jpg

  5. To set the circuit path protection, complete one of the following:
    • To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
    • To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
    • To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.
    Caution! Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
  6. If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:
    • Nodal Diversity Required-Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
    • Nodal Diversity Desired-Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
    • Link Diversity Only-Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
  7. If you selected Fully Protected Path in Step 12 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box.
  8. If you selected VT-DS3 Mapped Conversion in Step 11, complete the following substeps; otherwise, continue with Step 16:

    2. In the Conversion Circuit Route Constraints area, complete the following:
    • Node-Choose a node with a DS3XM-12 card installed.
    • Slot-Choose the slot where a DS3XM-12 card is installed.
    • DS3 Mapped STS-If applicable, choose Circuit Dest to indicate that the STS is the circuit destination, or Circuit Source to indicate that the STS is the circuit source.
  9. If you checked Using Required Nodes/Spans in Step 11 or Dual Ring Interconnect for a path protection configuration in Step 14, complete the following substeps. If you checked Dual Ring Interconnect for a BLSR, skip this step and continue with Step 17. If you did not select any of these options, continue with Step 18.
    1. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.
    2. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.
    3. Repeat Substep 2 for each node or span you wish to include or exclude.
    4. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
  10. Complete the "DLP-A563 Configure an Automatically Routed BLSR DRI" task.
  11. Click Next. If you are creating VT circuits, in the Create area of the VT Matrix Optimization page choose one of the following options. If not, continue with Step 18.
    • Create VT tunnel on transit nodes-This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s 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 15454 Reference Manual for more information.
    • Create VT aggregation point-This option is available if the DS-1 circuit source or destination is on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:
    • STS grooming node is source node, VT grooming node is destination node-Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.
    • STS grooming node is destination node, VT grooming node is source node-Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.
    • None-Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
  12. Click Next. If you selected Review Route Before Creation in Step 11, complete the following substeps; otherwise, continue with Step 20.
    1. Click Next.
    2. 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.
    3. 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 NTP-A185 Create a Manually Routed DS-3 or EC-1 Circuit.
  13. Click Finish. One of the following occurs if you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box:
    • If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.
    • If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 19 for each additional circuit. After completing the circuits, the Circuits window appears.

  3. From the View menu, choose Go to Network View.
  4. Click the Circuits tab, then click Create.
  5. In the Circuit Creation dialog box, complete the following fields:
    • Circuit Type-Choose STS. STS cross-connects will carry the DS-3 or EC-1 circuit across the ONS 15454 network.
    • Number of Circuits-Enter the number of DS-3 or EC-1 circuits that you want to create. The default is 1.
    • Auto-ranged-(Automatically routed circuits only) If you entered more than 1 in the Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in the Number of Circuits field.)
  6. Click Next.
  7. Define the circuit attributes (Figure 6-1):
    • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave this field blank, CTC assigns a default name to the circuit.
    • Size-For circuits on the DS3i-N-12 card, choose STS-3c. This sets a port group for Ports 1, 4, 7, and 10 using three ports at any given time. For VT2 circuits on the EC1 card, choose VT2. For all other circuits, choose STS-1.
    • Bidirectional-Leave this field checked (default).
    • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.
    • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
      • IS-Puts the circuit cross-connects in the IS-NR service state.
      • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
      • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
      • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
      For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
    • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
  • Protected Drops-Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
    • To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 17.
    • To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 17.

    Caution! Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

  6. If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:
    • Nodal Diversity Required-Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
    • Nodal Diversity Desired-Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
    • Link Diversity Only-Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

NTP-A187 Create a VT Aggregation Point

Purpose

This procedure creates a VT aggregation point (VAP). VAPs allow multiple DS-1 (VT1.5) circuits to be aggregated on a single STS on an OC-N, EC1, DS3, DS3E, DS3/EC1-48, DS3XM-6, or DS3XM-12 card. VAPs allow multiple VT1.5 circuits to pass through cross-connect cards without utilizing resources on the cross-connect card VT matrix. You also have the option to route the circuit through a portless transmultiplexing interface.

Tools/Equipment

For portless transmultiplexing configurations, a DS3XM-12 card must be installed on a node in the network.

Note: This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the "Network Element Defaults" appendix in the Cisco ONS 15454 Reference Manual.

Note: VT aggregation points can be created for circuits on BLSR, 1+1, or unprotected nodes. They cannot be created for circuits on path protection nodes.

Note: The maximum number of VAPs that you can create depends on the node protection topology and number of VT1.5 circuits that terminate on the node. Assuming that no other VT1.5 circuits terminate at the node, the maximum number of VAPs that you can terminate at one node is 8 for 1+1 protection and 12 for BLSR protection.

  1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the VT aggregation point. If you are already logged in, continue with Step 2.
  2. If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
  3. From the View menu, choose Go to Network View.
  4. Click the Circuits tab, then click Create.
  5. In the Circuit Creation dialog box, choose VT Aggregation Point from the Circuit Type list.
  6. Click Next.
  7. Define the circuit attributes (Figure 6-8):
    • Name-Assign a name to the VT aggregation point. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 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 VAP.
    • Size-Unavailable for VAPs.
    • Bidirectional-Unavailable for VAPs.
    • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
      • IS-Puts the circuit cross-connects in the IS-NR service state.
      • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
      • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
      • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
Note: A VAP automatically transitions into the IS service state after a VT circuit is created.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.

    • Node-Choose a node with a DS3XM-12 card installed.
    • Slot-Choose the slot where a DS3XM-12 card is installed.
    • DS3 Mapped STS-If applicable, choose Circuit Dest to indicate that the STS is the circuit destination, or Circuit Source to indicate that the STS is the circuit source.
  8. If you selected Using Required Nodes/Spans in Step 13:
    1. Click Next.
    2. In the Circuit Route Constraints area, click a span on the VAP map.
    3. Click Include to include the node or span in the VAP. Click Exclude to exclude the node or span from the VAP. The sequence in which you choose the nodes and spans sets the VAP sequence. Click spans twice to change the circuit direction.
    4. Repeat Substeps 2 and 3 for each node or span you wish to include or exclude.
    5. Review the VAP route. To change the tunnel routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists, then click the Up or Down buttons to change the tunnel routing order. Click Remove to remove a node or span.
  9. If you selected Review Route Before Creation in Step 13:
    1. Click Next.
    2. Review the tunnel route. To add or delete a tunnel span, choose a node on the tunnel route. Blue arrows show the tunnel 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.
    3. If the provisioned tunnel does not reflect the routing and configuration you want, click Back to verify and change tunnel information.
  10. Click Finish. The Circuits window appears.
  11. Verify that the VAP you just created appears in the circuits list. VAPs are identified in the Type column. The VAP tunnel automatically transitions into the IS-NR service state.

Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the "Network Element Defaults" appendix in the Cisco ONS 15454 Reference Manual.

  1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the circuit. If you are already logged in, continue with Step 2.
  2. If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
  3. Complete the following as necessary (you can provision Ethernet or packet-over-SONET [POS] ports before or after the STS circuit is created):
  4. From the View menu, choose Go to Network View.
  5. Click the Circuits tab, then click Create.
  6. In the Circuit Creation dialog box, complete the following fields:
    • Circuit Type-Choose STS.
    • Number of Circuits-Enter the number of optical circuits that 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 optical 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.
  7. Click Next.
  8. Define the circuit attributes (Figure 6-9):
    • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
    • Size-Choose the circuit size: VT2, STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-18c, STS-24c, STS-36c, STS-48c, or STS-192c. Valid circuit sizes for a G-Series or CE-MR-10 circuit are STS-1, STS-3c, STS6c, STS-9c, STS-12c, STS-24c, and STS-48c.
Note: Restrictions apply to provisioning multiple circuits on a G-Series card when one of the circuit sizes provisioned is STS-24c. Refer to the Cisco ONS 15454 Reference Manual for complete information.
  • Bidirectional-Leave checked for this circuit (default).
  • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.
  • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
  • IS-Puts the circuit cross-connects in the IS-NR service state.
  • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
  • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
  • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
  • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
  • Protected Drops-Check this check box if you want the circuit routed to protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

  5. To set the circuit path protection, complete one of the following:
    • To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
    • To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
    • To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 16.
  6. If you selected Fully Protected Path in Step 13 and the circuit will be routed on a path protection configuration, choose one of the following:
    • Nodal Diversity Required-Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
    • Nodal Diversity Desired-Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
    • Link Diversity Only-Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
  7. If you selected Fully Protected Path in Step 13 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box.
  8. Click Next.
  9. If you selected VT-DS3 Mapped Conversion in Step 12, complete the following substeps; otherwise, continue with Step 18:

    3. Click Next.
  10. If you checked Using Required Nodes/Spans in Step 12 or Dual Ring Interconnect for a path protection configuration in Step 15, complete the following substeps. If you checked Dual Ring Interconnect for a BLSR, skip this step and continue with Step 19. If you did not select any of these options, continue with Step 20.
    1. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.
    2. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.
    3. Repeat Substep 2 for each node or span you wish to include or exclude.
    4. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
  11. Complete the "DLP-A563 Configure an Automatically Routed BLSR DRI task.
  12. If you selected Review Route Before Creation in Step 12, complete the following substeps; otherwise, continue with Step 21.
    1. Click Next.
    2. 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.
    3. 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 NTP-A344 Create a Manually Routed Optical Circuit to assign the circuit route yourself.
  13. Click Finish. One of the following results occurs if you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box:
    • If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field.

    6. Click Next.
    7. Define circuit attributes (Figure 6-11):
      • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
      • Size-Choose the circuit size: VT2, STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-18c, STS-24c, STS-36c, STS-48c, or STS-192c.
      • Bidirectional-Uncheck this check box for this circuit.
      • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.
      • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
        • IS-Puts the circuit cross-connects in the IS-NR service state.
        • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
        • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
        • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
        For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
      • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
    Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
    • Protected Drops-Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

    9. Click Next.
    10. Define the circuit attributes:
      • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
      • Size-Choose the circuit size. Valid circuit sizes for an Ethernet multicard circuit are STS-1, STS-3c, and STS6c. Valid circuit sizes for an Ethernet single-card circuit are STS-1, STS-3c, STS6c, and STS12c.
      • Bidirectional-Leave the default unchanged (checked).
      • Create cross-connects only (TL1-like)-Uncheck this box; it does not apply to Ethernet circuits.
      • State-Choose IS (in service). Ethergroup circuits are stateless and always in service.
      • Apply to drop ports-Uncheck this box; states cannot be applied to E-Series Ethernet card ports.
      • Protected Drops-Leave the default unchanged (unchecked).
    11. If the circuit will be routed on a path protection configuration, complete the "DLP-A218 Provision Path Protection Selectors" task.

    Caution! Layer 1 SONET protection does not extend to multicard EtherSwitch circuits on path protection configurations.

    Caution! A TCC2/TCC2P card reset disrupts single-card and multicard EtherSwitch circuits for 45 seconds to two minutes. During this time, a spanning tree topology is created by the newly activated TCC2/TCC2P card.

    1. Click Next.
    2. Provision the circuit source:
      1. From the Node drop-down list, choose one of the EtherSwitch circuit endpoint nodes. (Either end node can be the EtherSwitch circuit source.)
      2. From the Slot drop-down list, choose one of the following:
      • If you are building a multicard EtherSwitch circuit, choose Ethergroup.
      • If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.
    3. Click Next.
    4. Provision the circuit destination:

      • If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.
    5. Click Next.
    6. In the Circuit VLAN Selection area, click New VLAN. If the desired VLAN already exists, continue with Step 20.
    7. Tip: You can also add VLANs in network view by choosing Tools > Manage VLANs. In the All VLANs dialog box, click the Create button to open the Define New VLAN dialog box.
    8. In the Define New VLAN dialog box, complete the following:
      • VLAN Name-Assign an easily identifiable name to your VLAN.
      • VLAN ID-Assign a VLAN ID. The VLAN ID should be the next available number between 2 and 4093 that is not already assigned to an existing VLAN. Each ONS 15454 network supports a maximum of 509 user-provisionable VLANs.
      • Topology Host-Choose the node to serve as the topology host from the drop-down list.
    9. Click OK.
    10. In the Circuit VLAN Selection area, highlight the VLAN name and click the arrow button (>>) to move the available VLANs to the Circuit VLANs column.
    11. 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 in the Disabling Spanning Tree dialog box. The Enable Spanning Tree box remains checked or unchecked for the creation of the next single-card, point-to-point Ethernet circuit. Caution! Disabling spanning-tree protection increases the likelihood of logic loops on an Ethernet network. Caution! Turning off spanning tree on a circuit-by-circuit basis means that the ONS 15454 is no longer protecting the Ethernet circuit and that the circuit must be protected by another mechanism in the Ethernet network. Caution! Multiple circuits with spanning tree protection enabled incur blocking if the circuits traverse the same E-Series card and use the same VLAN. Note: Spanning-tree rules prevent users from creating new circuits or modifying existing circuits if the circuits do not meet certain VLAN assignment constraints. If the VLAN set of the new circuit overlaps existing circuits, the same spanning-tree instance is used for all circuits. If the VLAN set of the new circuit overlaps with VLAN sets of existing circuits with different spanning-tree instances, the VLAN assignment fails. Cisco recommends that you plan VLAN assignments so that circuits with larger VLAN sets and a higher chance of overlap are added first. This means that if a circuit with an overlapping VLAN set is added, it collapses into the same spanning tree. To view circuits mapped to a spanning tree and their VLAN assignments, see the "DLP-A430 View Spanning Tree Information" task. 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.

      • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
        • IS-Puts the circuit cross-connects in the IS-NR service state.
        • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
        • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
        • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
        For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
      • Apply to drop ports-Check this check box if you want to apply the state chosen in the State field (IS or OOS-MT only) to the Ethernet circuit source and destination ports. You cannot apply OOS-AINS to E-Series Ethernet card ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports. For the requirements necessary to apply a service state to drop ports, refer to the Cisco ONS 15454 Reference Manual.
    Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

    Security Level

    Provisioning or higher

    Note: This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the "Network Element Defaults" appendix in the Cisco ONS 15454 Reference Manual.

    1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the VCAT circuit. If you are already logged in, continue with Step 2.
    2. Complete the following as necessary (you can provision Ethernet or POS ports before or after the VCAT circuit is created):
    3. From the View menu, choose Go to Network View.
    4. Click the Circuits tab, then click Create.
    5. In the Circuit Creation dialog box, choose STS-V or VT-V from the Circuit Type drop-down list. To create VT-V circuits, a CE-100T-8 or CE-MR-10 card must be installed or preprovisioned.
    6. Click Next.
    7. Define the circuit attributes (Figure 6-15):
      • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 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-Displays the circuit type you chose in Step 5. You cannot change it.
      • Bidirectional-Checked is the default. You cannot change it.
      • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits.
      • State-Choose IS.
      • Apply to drop ports-Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.
    Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
    • Symmetric-Checked is the default. You cannot change it.
    • Open VCAT-Check this check box if you are creating open-ended VCAT circuits. For more information on open-ended VCAT, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
    • Member size-Choose the member size. For information about the member size supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
    • Num. of members-Choose the number of members. For information about the number of members supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
    • Mode-Choose the protection mode for the VCAT circuit. For information about the mode supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
      • None-Provides no protection. A failure on one member causes the entire VCAT circuit to fail. For CE-Series cards, you can add or delete members after creating a VCAT circuit with no protection. During the time it takes to add or delete members (from seconds to minutes), the entire VCAT circuit will be unable to carry traffic. For all other cards, you cannot add or delete members if the protection mode is None.
      • Sw-LCAS-(Software link capacity adjustment scheme [LCAS]) Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. Sw-LCAS uses legacy SONET failure indicators like path alarm indication signal (AIS-P) and path remote defect indication (RDI-P) to detect member failure.
      • LCAS-Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members, and if a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.
    Note: Cisco recommends using LCAS for CE-100T-8 cards that do not need to interoperate with ML-Series cards.
    Note: For CE-MR-10 card, before you create a VCAT circuit with LCAS protection mode, it is recommended that you put all members of the VCAT circuit being created in OOS-OOG service state and later move them to IS state.

    1. Click Next.
    2. Complete the "DLP-A324 Provision a VCAT Circuit Source and Destination" task for the VCAT circuit you are creating. If you are creating an open-ended VCAT circuit, complete the "DLP-A579 Provision an Open VCAT Circuit Source and Destination" task.
    3. In the VCAT Circuit Routing Preferences area (Figure 6-16), check Route Automatically. Two options are available; choose either, both, or none based on your preferences.
      • Using Required Nodes/Spans-Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.
      Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
      • Review Route Before Creation-Check this check box to review and edit the circuit route before the circuit is created.

    4. If the VCAT circuit has a source or destination on a CE-Series card, choose one of the following routing types.
      • Common Routing-Routes the members on the same fiber.
      • Split Routing-Allows the individual members to be routed on different fibers or each member to have different routing constraints. Split routing is required when creating circuits over a path protection configuration.
      If the VCAT circuit does not have a source or destination on a CE-Series card, common routing is automatically selected and you cannot change it.
    5. If you want to set preferences for individual members, complete the following in the Member Preferences area. Repeat for each member. To set identical preferences for all members, skip this step and continue with Step 13:
      • Number-Choose a number (between 1 and 256) from the drop-down list to identify the member.
      • Name-Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.
      • Protection-Choose the member protection type:
        • Fully Protected-Routes the circuit on a protected path.
        • Unprotected-Creates an unprotected circuit.
        • PCA-Routes the circuit on a BLSR protection channel.
        • DRI-(Split routing only) Routes the member on a dual-ring interconnect circuit.
      • Node-Diverse Path-(Split routing only) Available for each member when Fully Protected is chosen.
    6. To set preferences for all members, complete the following in the Set Preferences for All Members area:
      • Protection-Choose the member protection type:
        • Fully Protected-Routes the circuit on a protected path.
        • Unprotected-Creates an unprotected circuit.
        • PCA-Routes the member on a BLSR protection channel.

      2. Click a node or span on the circuit map.
      3. Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.
      4. Repeat Substeps 2 and 3 for each node or span you wish to include or exclude.
      5. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
      6. Repeat Substeps 1 through 5 for each member.

    1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the circuit. If you are already logged in, continue with Step 2.
    2. If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
    3. Complete the following as necessary (you can provision Ethernet or POS ports before or after the VCAT circuit is created):
    4. From the View menu, choose Go to Network View.
    5. In the Circuit Creation dialog box, choose STS-V or VT-V from the Circuit Type drop-down list. To create VT-V circuits, a CE-100T-8 or CE-MR-10 card must be installed or preprovisioned.
    6. Click Next.
    7. Define the circuit attributes (Figure 6-15):
      • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 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-Displays the circuit type you chose in Step 5. You cannot change it.
      • Bidirectional-Checked is the default. You cannot change it.
      • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits.
      • State-Choose IS.
      • Apply to drop ports-Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.
      • Symmetric-Checked is the default. You cannot change it.
      • Open VCAT-Check this check box if you are creating open-ended VCAT circuits. For more information on open-ended VCAT refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.

      • Num. of members-Choose the number of members. For information about the number of members supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual. You can add additional memebrs using the Edit circuit function.
      • Mode-Choose the protection mode for the VCAT circuit. For information about the mode supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
        • None-Provides no protection. A failure on one member causes the entire VCAT circuit to fail. For CE-Series cards, you can add or delete members after creating a VCAT circuit with no protection. During the time it takes to add or delete members (from seconds to minutes), the entire VCAT circuit will be unable to carry traffic. For all other cards, you cannot add or delete members if the protection mode is None.
        • Sw-LCAS-Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. Sw-LCAS uses legacy SONET failure indicators like AIS-P and RDI-P to detect member failure.
        • LCAS-Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members, and if a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.
      Note: Cisco recommends using LCAS for CE-T100-8 cards that do not need to interoperate with the ML-Series cards.
      Note: For CE-MR-10 card, before you create a VCAT circuit with LCAS protection mode, it is recommended that you put all members of the VCAT circuit being created in OOS-OOG service state and later move them to IS state.

      • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.
      • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
        • IS-Puts the circuit cross-connects in the IS-NR service state.
        • OOS,DSBLD-Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
        • IS,AINS-Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
        • OOS,MT-Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
        For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
      • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
      Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
      • Protected Drops-Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

      • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
      • Size-If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.
      • Bidirectional-Leave checked for this circuit (default).
      • Create cross-connects only (TL1-like)-Check this check box to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you are creating an open-ended path protection circuit to bridge VT traffic, you must check this check box.
      • Diagnostic-Leave unchecked.
      • State-Choose the administrative state to apply to all of the cross-connects in a circuit:
        • IS-Puts the circuit cross-connects in the In-Service and Normal (IS-NR) service state.
        • OOS,DSBLD-Puts the circuit cross-connects in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD) service state. Traffic is not passed on the circuit.
        • IS,AINS-Puts the circuit cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS) service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.
        • OOS,MT-Puts the circuit cross-connects in the Out-of-Service and Management, Maintenance (OOS-MA,MT) service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the "DLP-A230 Change a Circuit Service State" task.
        For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
      • Apply to drop ports-Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.
    Note: If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.
    • Protected Drops-Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC displays only protected cards and ports as source and destination choices.
    1. If the circuit will be routed on a path protection configuration, complete the "DLP-A218 Provision Path Protection Selectors" task. Otherwise, continue with the next step.
    2. Click Next.
    3. Complete one of the following, depending on the source and destination cards. Choose single source and secondary destinations to create the open-ended path protection circuit:
    4. In the Circuit Routing Preferences area (Figure 6-2), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.
      • Using Required Nodes/Spans-Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.
      Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
      • Review Route Before Creation-Check this check box if you want to review and edit the circuit route before the circuit is created.
    5. Leave Fully Protected Path checked.
    6. Choose one of the following:
      • Nodal Diversity Required-Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
      • Nodal Diversity Desired-Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
      • Link Diversity Only-Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
    7. If you selected Using Required Nodes/Spans in Step 11, complete the following substeps. If not, continue with Step 15.
      1. Click Next.
      2. In the Circuit Route Constraints area, click a node or span on the circuit map.
      3. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.
      4. Repeat Substeps 2 and 3 for each node or span you wish to include or exclude.
      5. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
    8. Click Next. If the circuit you are creating is a VT circuit for routing traffic over an ONS 15600 hub node, in the Create area of the VT Matrix Optimization page choose Create VT tunnel on transit nodes and click Next. If not, continue with Step 16.
    9. This option is available if the 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 15454s 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 15454 Reference Manual for more information.

    10. If you selected Review Route Before Creation in Step 11, complete the following substeps. If not, continue with Step 17.
      1. Click Next.
      2. 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.
      3. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information.
    11. Click Finish. One of the following results occurs if you entered more than one circuit in the Number of Circuits field on the Circuit Creation dialog box.
      • If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.
      • If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 17 for each additional circuit. After completing the circuits, the Circuits window appears.
    12. In the Circuits window, verify that the new circuits appear in the circuits list.
    13. Complete one of the following to test the circuit. Skip this step if you built a test circuit.
    Stop. You have completed this procedure.

    1. Complete the "DLP-A60 Log into CTC" task at the node where you will create the circuit. If you are already logged in, continue with Step 2.
    2. In the node view, double-click the CE-MR-10 card.
    3. Complete the NTP-A595 Provision Card Mode for CE-MR-10 Card to change the card mode to Manual.
    4. Click the Circuits > Circuits tabs and click Create.
    5. In the Circuit Creation dialog box, choose STS-V or VT-V from the Circuit Type drop-down list.
    6. Click Next.
    7. Define the circuit attributes:
      • Name-Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 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-Displays the circuit type that you chose in Step 5. You cannot change it.
      • Bidirectional-Checked is the default. You cannot change it.
      • Create cross-connects only (TL1-like)-Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits.
      • State-Choose IS.
      • Apply to drop ports-Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.
      • Symmetric-Checked is the default. You cannot change it.
      • Open VCAT-Check this check box if you are creating open-ended CCAT/VCAT circuits. For more information on open-ended CCAT/VCAT refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
      • Member size-Choose the member size. For information about the member size supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
      • Num. of members-Choose the number of members. For information about the number of members supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual. You can add additional memebrs using the Edit circuit function.
      • Mode-Choose the protection mode for the CCAT/VCAT circuit. For information about the mode supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
        • None-Provides no protection. A failure on one member causes the entire VCAT circuit to fail. For CE-MR-10 cards, you can add or delete members after creating a VCAT circuit with no protection. During the time it takes to add or delete members (from seconds to minutes), the entire VCAT circuit will be unable to carry traffic. For all other cards, you cannot add or delete members if the protection mode is None.
        • SW-LCAS-Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. Sw-LCAS uses legacy SONET failure indicators like AIS-P and RDI-P to detect member failure.
        • LCAS-Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members, and if a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.
    Note: For CE-MR-10 card, before you create a VCAT circuit with LCAS protection mode, it is recommended that you put all members of the VCAT circuit being created in OOS-OOG service state and later move them to IS state.
    1. Click Next.
    2. Complete the "DLP-A324 Provision a VCAT Circuit Source and Destination" task for the CCAT/VCAT circuit you are creating. If you are creating an open-ended VCAT circuit, complete the "DLP-A579 Provision an Open VCAT Circuit Source and Destination" task.
    3. In the CCAT/VCAT Circuit Routing Preferences area, uncheck Route Automatically.
    4. If the CCAT/VCAT circuit has a source or destination on a CE-Series card, choose one of the following routing types.
      • Common Fiber Routing-Routes the members on the same fiber.
      • Split Routing-Allows the individual members to be routed on different fibers or each member to have different routing constraints. Split routing is required when creating circuits over a path protection configuration.
      If the CCAT/VCAT circuit does not have a source or destination on a CE-MR-10 card, common routing is automatically selected and you cannot change it.
    5. If you want to set preferences for individual members, complete the following in the Member Preferences area. Repeat for each member. To set identical preferences for all members, skip this step and continue with Step 13.
      • Number-Choose a number (between 1 and 256) from the drop-down list to identify the member.
      • Name-Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.
      • Protection-Choose the member protection type:
        • Fully Protected-Routes the circuit on a protected path.
        • Unprotected-Creates an unprotected circuit.
        • PCA-Routes the member on a BLSR protection channel.
        • DRI-(Split routing only) Routes the member on a dual-ring interconnect circuit.
      • Node-Diverse Path-(Split routing only) Available for each member when Fully Protected is chosen.
    6. To set preferences for all members, complete the following in the Set Preferences for All Members area:
      • Protection-Choose the member protection type:
        • Fully Protected-Routes the circuit on a protected path.
        • Unprotected-Creates an unprotected circuit.
        • PCA-Routes the member on a BLSR protection channel.
        • DRI-(Split routing only) Routes the member on a dual-ring interconnect circuit.
      • Node-Diverse Path-(Split routing only) Available when Fully Protected is chosen.
    7. Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.
    8. In the Route Review and Edit area, node icons appear so you can route the circuit manually.
    9. Complete the "DLP-A325 Provision a VCAT Circuit Route" task.
    10. Click Finish. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.
    11. Note: Depending on the complexity of the network and number of members, the VCAT circuit creation process can take several minutes.
    12. When all the circuits are created, the main Circuits window appears. Verify that the circuit you created appear in the window.
    Stop. You have completed this procedure.
