Create Circuits and VT Tunnels

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, DS3i-N-12, 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.

¹You can route one STS circuit on a DS1 card to carry all 14 ports within the STS. However, 14 VT1.5s are not utilized.

²The number of "portless" interfaces depends on the system configuration. For XCVT drop slots, a maximum of 6 portless transmultiplexing interfaces are supported. For XCVT trunk slots and for the XC10G and XC-VXC-10G any slot, a maximum of 12 portless transmultiplexing interfaces are supported.

³Dependent on the SFP used in a port, the available backplane width, and existing provisioned lines. For more details, refer to the "Optical Cards" chapter in the Cisco ONS 15454 Reference Manual.

NTP-A127 Verify Network Turn Up


Purpose	This procedure verifies that the ONS 15454 network is ready for circuit provisioning.
Tools/Equipment	None
Prerequisite Procedures	Chapter 5 "Turn Up a Network"
Required/As Needed	Required
Onsite/Remote	Onsite or remote
Security Level	Provisioning or higher

Step 1 Complete the "DLP-A60 Log into CTC" task. If you are already logged in, continue with Step 2.

Step 2 From the View menu, choose Go to Network View. Wait for all the nodes that are part of the network to appear on the network map. (Large networks might take several minutes to display all the nodes.)

Note If this is the first time your computer has connected to this ONS 15454 network, the node icons are stacked on the left side of the graphic area, possibly out of view. Use the scroll bar under the network map to display the icons. To separate the icons, press Ctrl and drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.

Step 3 Verify node accessibility. In network view, all node icons must be either green, yellow, orange, or red.

If all network nodes do not appear after a few minutes, or if a node icon is gray with "Unknown" under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see Chapter 5 "Turn Up 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.

Step 4 Verify DCC connectivity. All nodes must be connected by green lines. If lines are missing or gray in color, do not continue. See Chapter 5 "Turn Up a Network" and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing.

Step 5 Click the Alarms tab to view alarm descriptions. Investigate and resolve, if necessary, all critical (red node icon) or major (orange node icon) alarms. Refer to the Cisco ONS 15454 Troubleshooting Guide to resolve alarms before continuing.

Step 6 From the View menu, choose Go to Home View. Verify that the node is provisioned according to your site or engineering plan:

a. View the cards in the shelf map. Verify that the ONS 15454 cards appear in the specified slots.

b. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and Network Time Protocol/Simple Network Time Protocol (NTP/SNTP) server IP address (if used) are correctly provisioned. If needed, make corrections using the "NTP-A25 Set Up Name, Date, Time, and Contact Information" procedure.

c. Click the Network tab. Verify that the IP address, Subnet Mask, Default Router, Prevent LCD IP Config, and Gateway Settings are correctly provisioned. If not, make corrections using the "NTP-A169 Set Up CTC Network Access" procedure.

d. Click the Protection tab. Verify that protection groups are created as specified in your site plan. If the protection groups are not created, complete the "NTP-A324 Create Protection Groups" procedure.

e. If the node is in a BLSR, click the BLSR tab. (If the node is not in a BLSR, continue with Step f.) Verify that the following items are provisioned as specified in your site plan:

•BLSR type (2-fiber 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" procedure for instructions.

f. 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" procedure to correct the information.

g. If Simple Network Management Protocol (SNMP) is used, click the SNMP tab and verify the trap and destination information. If the information is not correct, see the "NTP-A87 Change SNMP Settings" procedure to correct the information.

h. 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 Chapter 5 "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

i. Click the Timing tab. Verify that timing is provisioned as specified. If not, use the "NTP-A85 Change Node Timing" procedure to make the changes.

j. Click the Alarm Profiles tab. If you provisioned optional alarm profiles, verify that the alarms are provisioned as specified. If not, see the "NTP-A71 Create, Download, and Assign Alarm Severity Profiles" procedure to change the information.

k. Verify that the network element (NE) defaults listed in the status area of the node view window are correct.

Step 7 Repeat Step 6 for each node in the network.

Step 8 Complete the appropriate circuit creation procedure from the NTP list in the "Before You Begin" section.

Stop. You have completed this procedure.

NTP-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.
Tools/Equipment	None
Prerequisite Procedures	A127 Verify Network Turn Up
Required/As Needed	As needed
Onsite/Remote	Onsite or remote
Security Level	Provisioning or higher

Step 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.

Step 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.

Step 3 From the View menu, choose Go to Network View.

Step 4 Click the Circuits tab, then click Create.

Step 5 In the Circuit Creation dialog box, complete the following fields:

•Circuit Type—Choose VT 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.

Step 6 Click Next.

Step 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.

Figure 6-1 Setting Circuit Attributes for a DS-1 Circuit

Step 8 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors" task. Otherwise, continue with the next step.

Step 9 Click Next.

Step 10 Complete the "DLP-A95 Provision a DS-1 Circuit Source and Destination" task.

Step 11 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

Step 12 To set the circuit path protection, complete one of the following:

•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.

•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.

Caution

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

Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:

•Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.

•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection dual-ring interconnect (DRI), check the Dual Ring Interconnect check box.

Step 15 If you selected Using Required Nodes/Spans in Step 11, complete the following substeps. If not, continue with Step 17.

a. Click Next.

b. In the Circuit Route Constraints area, click a node or span on the circuit map.

c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.

d. Repeat Steps b and c for each node or span you wish to include or exclude.

e. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 16 Click Next. In the Create area of the VT Matrix Optimization 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, 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.

Step 17 If you selected Review Route Before Creation in Step 11, complete the following substeps. If not, continue with Step 18.

a. Click Next.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "NTP-A182 Create a Manually Routed DS-1 Circuit" procedure.

Step 18 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.

Step 19 In the Circuits window, verify that the new circuits appear in the circuits list.

Step 20 Complete the "NTP-A135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.

Stop. You have completed this procedure.

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.

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.

Step 8 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors" task. Otherwise, continue with the next step.

Step 11 In the Circuit Routing Preferences area (Figure 6-2), uncheck Route Automatically.

Step 12 To set the circuit path protection, complete one of the following:

•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.

•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 16.

Caution

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

Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose a Node-Diverse Path option:

•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

•Nodal Diversity Desired— Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, check the Dual Ring Interconnect check box.

Step 15 Click Next. In the Create area of the VT Matrix Optimization page, choose one of the following:

•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14.

•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.

Caution

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

Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on a path protection, choose one of the following:

•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Step 15 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.

Step 16 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 18.

Step 17 If you checked Dual Ring Interconnect in Step 15 for a BLSR DRI, complete the following substeps to assign primary and secondary nodes.

a. In the Route/Review Edit area, click the BLSR-DRI Nodes tab.

b. Click Add BLSR DRI.

c. In the BLSR DRI Options dialog box, complete the following (Figure 6-12):

•Primary Node—For a traditional or integrated BLSR-DRI, choose the node where the circuit interconnects the rings.

•Secondary Node—For a traditional or integrated BLSR-DRI, choose the secondary node for the circuit to interconnect the rings. This route is used if the route on the primary node fails.

•Primary Node #2—For a traditional BLSR-DRI where two primary nodes are required to interconnect rings, choose the second primary node.

•Secondary Node #2—For a traditional BLSR-DRI where two secondary nodes are required, choose the second secondary node.

d. Click OK.

e. Review the circuit constraints. To change the circuit routing order, choose a node in the Required Nodes/Links list and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

f. Click the Included Spans tab, and continue with Step 18.

Step 18 Complete the "DLP-A369 Provision an OC-N Circuit Route" task.

Step 19 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. If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, the Circuit Creation dialog box appears after the circuit is created so you can create the remaining circuits. Repeat Steps 6 through 18 for each additional circuit.

Step 20 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created appear in the window.

Step 21 Complete the following as necessary. Skip this step if you built a test circuit.

a. Complete the "NTP-A62 Test Optical Circuits" procedure.

b. Complete the "NTP-A149 Test G-Series Circuits" procedure.

Stop. You have completed this procedure.

NTP-A314 Create a Unidirectional Optical Circuit with Multiple Drops


Purpose	This procedure creates a unidirectional optical circuit with multiple traffic drops (circuit destinations).
Tools/Equipment	For VT2 circuits, the XC-VXC-10G card must be installed at the circuit source and destination nodes.
Prerequisite Procedures	A127 Verify Network Turn Up
Required/As Needed	As needed
Onsite/Remote	Onsite or remote
Security Level	Provisioning or higher

Step 1 Complete the "DLP-A60 Log into CTC" task on the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.

Step 3 From the View menu, choose Go to Network View.

Step 4 Click the Circuits tab, then click Create.

Step 5 In the Circuit Creation dialog box, complete the following fields:

•Circuit Type—Choose STS.

•Number of Circuits—Leave the default unchanged (1).

•Auto-ranged—Unavailable when the Number of Circuits field is 1.

Step 6 Click Next.

Step 7 Define circuit attributes (Figure 6-13):

•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.

•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.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in 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.

Step 8 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors" task.

Step 9 Click Next.

Step 10 Complete the "DLP-A97 Provision an OC-N Circuit Source and Destination" task for the circuit that you are creating.

Step 11 Uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.

Step 12 To set the circuit path protection, complete one of the following:

•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.

Caution

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

Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:

•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Note For manually routed circuits, CTC checks your manually provisioned path against the path diversity option you choose. If the path does not meet the path diversity requirement that is specified, CTC displays an error message.

Step 14 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.

Step 15 Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually.

a. Click a node or span on the circuit map.
