Table 5-1 defines ONS 15310-MA SDH circuit creation terms and options.
Table 5-1 ONS 15310-MA SDH Circuit Options
|
|
Source |
The circuit source is where the circuit enters the ONS network. |
Destination |
The circuit destination is where the circuit exits an ONS 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 (VC high-order path) or VC low-order path 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). |
VCAT |
Virtual concatenated (VCAT) circuits transport traffic using noncontiguous time division multiplexing (TDM) time slots, avoiding the bandwidth fragmentation problem that exists with contiguous concatenated (CCAT) circuits. The cards that support VCAT circuits are the CE-100T-8, CE-MR-6, and ML-100T-8 cards. For more information, refer to the Cisco ONS 15310-MA SDH Reference Manual. |
VC low-order path tunnel |
VC low-order path tunnels allow VC-12 circuits to pass through a node without utilizing cross-connect resources. VC low-order path circuits using VC low-order path tunnels use cross-connect capacity only at the source and destination nodes. One VC low-order path tunnel can carry 28 VC-12 circuits. |
VC low-order path aggregation point |
VC low-order path aggregation points (VAPs) allow VC low-order path circuits to be aggregated into a VC high-order path for handoff to non-ONS networks or equipment, such as interoffice facilities (IOFs), switches, or digital access cross-connect systems (DACS). VAPs reduce VC low-order path matrix resource utilization at the node where the VC11s are aggregated onto the VC high-order path. This node is called the VC high-order path grooming end. The VC grooming end requires an STM-M port. VC low-order path aggregation points can be created on 1+1 or unprotected nodes, but cannot be created on path protection nodes. |
Table 5-2 shows the circuit source and destination options for ONS 15310-MA SDH VC low-order path circuits.

Step 1
Complete the "DLP-H29 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 network, the node icons will be stacked on the left side of the graphic area, possibly out of view. Use the scroll bar below the network map to display the icons. To separate the icons, drag and drop an icon to a new location. Repeat until all the nodes are visible on the graphic area.
Step 3
Verify node accessibility. In the network view, all node icons must be either green, yellow, orange, or red.
If all network nodes do not appear after a few minutes, or if a node icon is gray with "Unknown" under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see Chapter 4 "Turn Up a Network" to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15310-MA SDH Troubleshooting Guide.
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 4 "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 and click Synchronize.
a.
Verify that the alarm filter is not on. See the "DLP-H88 Disable Alarm Filtering" task as necessary.

Onsite or remote |
Security Level |
Provisioning or higher |
Step 1
Complete the "DLP-H29 Log into CTC" task at a node on the network where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2
If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-H56 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 VC high-order path or VC low-order path. VC high-order path or VC low-order path cross-connects will carry the E1 circuit across the ONS network.
•
Number of Circuits—Enter the number of E1 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 autoranging 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. Autoranging creates identical (same source and destination), sequential circuits automatically. Uncheck this check box if you do not want CTC to create sequential circuits automatically.
Step 6
Click Next.
Step 7
Define the circuit attributes (Figure 5-1):
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
Size—If you are creating a VC high-order path circuit, choose VC4. If you are creating a VC low-order path circuit, Size displays VC12 and VC3.
•
Bidirectional—Leave the default unchanged (checked) for this circuit.
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VC low-order path 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:
–
unlocked—Puts the circuit cross-connects in the In-Service and Normal (unlocked-enabled) service state.
–
locked, outOfGroup—Puts the circuit cross-connects in the Out-of-Service and Management, Disabled (locked-enabled,disabled) service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the circuit cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (unlocked-disabled,automaticInService) service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to unlocked-enabled.
–
locked, maintenance—Puts the circuit cross-connects in the Out-of-Service and Management, Maintenance (locked-enabled,maintenance) service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use locked, maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; Automatic In Service; or locked, outOfGroup when testing is complete. See the "DLP-H111 Change a Circuit Service State" task.
Note
If VC low-order path circuit source and destination ports are in an unlocked-disabled,automaticInService; locked-enabled,maintenance; or unlocked-enabled service state, VC low-order path circuits in unlocked-disabled,automaticInService change to unlocked-enabled even if a physical signal is not present.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15310-MA SDH Reference Manual.
•
Apply to drop ports—Check this check box 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 is 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 unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to unlocked-disabled,FLT.
•
Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ports that are in 1+1 protection. If you check this check box, CTC displays only protected cards and ports as source and destination choices.
Figure 5-1 Setting Circuit Attributes for a E1 Circuit
Step 8
If the circuit will be routed on a path protection configuration, complete the "DLP-H57 Provision Path Protection Selectors During Circuit Creation" task. Otherwise, continue with the next step.
Step 9
Click Next.
Step 10
Complete the "DLP-H58 Provision a E1 Circuit Source and Destination" task.
Step 11
In the Circuit Routing Preferences area, click Route Automatically. Two options are available; choose either, both, or none based on your preferences.
•
Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
•
Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.
Step 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.
Step 13
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.
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 will be routed. Click spans twice to change the circuit direction.
d.
Repeat Step c for each node or span you want to include or exclude.
e.
Review the circuit route. To change the circuit routing order, choose a node from the Required Nodes/Lines or Excluded 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
If you are creating a VC high-order path circuit, skip this step and continue with Step 17. If you are creating a VC low-order path circuit, click Next and complete the "DLP-H59 Provision VC high-order path and VC Low-order Path Grooming Nodes" task.
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 the circuit information. If the circuit needs to be routed to a different path, see the "NTP-H38 Create a Manually Routed E1 Circuit" procedure.
Step 18
Click Finish. One of the following results occurs, depending on the circuit properties you chose in the Circuit Creation dialog box:
•
If you entered 1 in the Number of Circuits field, CTC creates the circuit.
•
If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If autoranging 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 autoranging. After completing the circuits, the Circuits window appears.
•
If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears for you to 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-H46 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

•
Number of Circuits—Enter the number of E1 circuits that you want to create. The default is 1.
•
Auto-ranged—Applies to automatically routed circuits only. If you entered more than 1 in Number of Circuits, uncheck this check box. (The check box is unavailable if only one circuit is entered in Number of Circuits.)
Step 6
Click Next.
Step 7
Define the circuit attributes (Figure 5-1):
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
Size—If you are creating a VC high-order path circuit, choose VC3. If you are creating a VC low-order path circuit, Size displays VC-12 and cannot be changed.
•
Bidirectional—Leave the default unchanged (checked) for this circuit.
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VC low-order path tunnels and Ethergroup sources and destinations are unavailable.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–
unlocked—Puts the circuit cross-connects in the unlocked-enabled service state.
–
locked, outOfGroup—Puts the circuit cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the circuit cross-connects in the unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to unlocked-enabled.
–
locked, maintenance—Puts the circuit cross-connects in the locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use locked, maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; Automatic In Service; or locked, outOfGroup when testing is complete. See the "DLP-H111 Change a Circuit Service State" task.
Note
If VC low-order path circuit source and destination ports are in an unlocked-disabled,automaticInService; locked-enabled,maintenance; or unlocked-enabled service state, VC low-order path circuits in unlocked-disabled,automaticInService change to unlocked-enabled even if a physical signal is not present.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15310-MA SDH Reference Manual.
•
Apply to drop ports—Check this check box 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 is 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 unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to unlocked-disabled,FLT.
•
Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ports that are in 1+1 protection. If you check this check box, CTC displays only protected cards and ports as source and destination choices.
Step 8
If the circuit will be routed on a path protection configuration, complete the "DLP-H57 Provision Path Protection Selectors During Circuit Creation" task. Otherwise, continue with the next step.
Step 9
Click Next.
Step 10
Complete the "DLP-H58 Provision a E1 Circuit Source and Destination" task.
Step 11
In the Circuit Routing Preferences area, 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.
Step 13
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.
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
If you are creating a VC high-order path circuit, skip this step and continue with Step 16. If you are creating a VC low-order path circuit, click Next and complete the "DLP-H59 Provision VC high-order path and VC Low-order Path Grooming Nodes" task.
Step 16
Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

Step 6
Click Next.
Step 7
Define the circuit attributes:
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
Size—If you are creating a VC high-order path circuit, choose VC3. If you are creating a VC low-order path circuit, Size displays VC-12 and cannot be changed.
•
Bidirectional—Uncheck for this circuit.
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this check box is checked, you cannot assign a name to the circuit. Also, VC low-order path tunnels and Ethergroup sources and destinations are unavailable.
•
Diagnostic—Leave the default (unchecked) unchanged.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–
unlocked—Puts the circuit cross-connects in the unlocked-enabled service state.
–
locked, outOfGroup—Puts the circuit cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the circuit cross-connects in the unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to unlocked-enabled.
–
locked, maintenance—Puts the circuit cross-connects in the locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use locked, maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; Automatic In Service; or locked, outOfGroup when testing is complete. See the "DLP-H111 Change a Circuit Service State" task.
Note
If VC low-order path circuit source and destination ports are in an unlocked-disabled,automaticInService; locked-enabled,maintenance; or unlocked-enabled service state, VC low-order path circuits in unlocked-disabled,automaticInService change to unlocked-enabled even if a physical signal is not present.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15310-MA SDH Reference Manual.
•
Apply to drop ports—Check this check box 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 is 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 unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to unlocked-disabled,FLT.
•

In the Define New Drop dialog box, define the new drop:
a.
Node—Choose the target node for the circuit drop.
b.
Slot—Choose the target card and slot.
c.
Port, VC high-order path—Choose the port and/or VC high-order path from the Port and VC high-order path drop-down lists. The card selected in Step b determines whether port, VC high-order path, or both lists display. See Table 5-1 for a list of options.
d.
VC low-order path—If applicable, choose the VC low-order path from the VC low-order path drop-down list.
e.
The routing preferences for the new drop will match those of the original circuit. If the original circuit was routed on a protected path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 13 for option descriptions.
f.
If you want to change the circuit state, choose the circuit state from the Target Circuit State drop-down list. The state chosen applies to the entire circuit.
g.
Check Apply to drop ports if you want to apply the state chosen in the Target Circuit State to the circuit source and destination drops.
h.

b.
Attach the loopback cable to the port you are testing. Connect the Tx connector to the Rx connector of the port being tested.
Step 7
Attach loopback cables to the circuit source node:
a.
Test the loopback cable by connecting one end to the test set Tx port and the other end to the test set Rx port. If the test set does not run error-free, check the cable for damage and check the test set to make sure it is set up correctly.
b.
Attach the loopback cable to the port you are testing. Connect the test set to the circuit source port. Connect the Tx port of the test set to the circuit Rx port, and the test set Rx port to the circuit Tx port.
Step 8
Configure the test set for the card that is the source of the circuit you are testing:
•
E1—If you are testing an unmultiplexed E1, you must have a DSX-1 panel or use the high-density E1 interface through the LFH-96 connector. Set the test set for E1. For information about configuring your test set, consult your test set user guide.
•
DS-3/E3—If you are testing a clear channel DS-3 or E3, you must have a direct DS-3/E3 interface into the node through the broadband electrical (BBE) ports on the CTX card. Set the test set for clear channel DS-3. For information about configuring your test set, consult your test set user guide.
Step 9
Verify that the test set displays a clean signal. If a clean signal does not appear, repeat Steps 2 through 8 to make sure the test set and cabling is configured correctly.
Step 10

locked, disabled—Puts the circuit cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the circuit cross-connects in the unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to unlocked-enabled.
–
locked, maintenance—Puts the circuit cross-connects in the locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use locked, maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; Automatic In Service; or locked, outOfGroup when testing is complete. See the "DLP-H111 Change a Circuit Service State" task.

•
Auto-ranged—This check box is automatically checked when you enter more than 1 in the Number of Circuits field. Leave checked if you are creating multiple optical circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck this check box if you do not want CTC to create the circuits automatically.
Step 6
Click Next.
Step 7
Define the circuit attributes:
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
Size—Choose the optical circuit size. If you are creating an VC high-order path circuit, the choices are VC3, VC4, VC4-2c, VC4-3c, or VC4-4c. If you are creating a VC low-order path circuit, the Size displays VC-12. You cannot change it.
•
Bidirectional—Leave the default (checked) for this circuit.
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VC low-order path tunnels and Ethergroup sources and destinations are unavailable.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–
unlocked—Puts the circuit cross-connects in the unlocked-enabled service state.
–
locked, disabled—Puts the circuit cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the circuit cross-connects in the unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to unlocked-enabled.
–
locked, maintenance—Puts the circuit cross-connects in the locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use locked, maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; Automatic In Service; or locked, outOfGroup when testing is complete. See the "DLP-H111 Change a Circuit Service State" task.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15310-MA SDH Reference Manual.
•
Apply to drop ports—Check this check box 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 is 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 unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to unlocked-disabled,FLT.
•
Protected Drops—Check this check box if you want the circuit routed to protected drops only, that is, to ports that are in 1+1 protection. If you check this check box, CTC displays only protected cards as source and destination choices.
Step 8
If the circuit will be routed on a path protection configuration, complete the "DLP-H57 Provision Path Protection Selectors During Circuit Creation" task.
Step 9
Click Next.
Step 10
Complete the "DLP-H63 Provision an STM-M Circuit Source and Destination" task for the optical circuit that you are creating.
Step 11
In the Circuit Routing Preferences area, choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.
•
Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.
•
Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.
Step 12
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.
Step 13
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.
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
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, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit will be routed. Click spans twice to change the circuit direction.
d.
Repeat Step c for each node or span you want 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, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Step 16
If you are creating an VC high-order path circuit, skip this step and continue with Step 17. If you are creating a VC low-order path circuit, click Next and complete the "DLP-H59 Provision VC high-order path and VC Low-order Path Grooming Nodes" task.
Step 17
If you selected Review Route Before Creation in Step 11, complete the following substeps; otherwise, 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 the circuit information. If the circuit needs to be routed to a different path, see the "NTP-H48 Create a Manually Routed Optical Circuit" procedure to assign the circuit route yourself.
Step 18
Click Finish. One of the following results occurs, based on the circuit properties you provisioned in the Circuit Creation dialog box:
•
If you entered 1 in the Number of Circuits field, CTC creates the circuit.
•
If you entered more than 1 in Number of Circuits and chose Auto-ranged, CTC automatically creates the number of circuits entered in Number of Circuits. If autoranging cannot complete all the circuits, for example, because sequential ports are unavailable on the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue autoranging. After completing the circuits, the Circuits window appears.
•
If you entered more than 1 in Number of Circuits and did not choose Auto-ranged, the Circuit Creation dialog box appears for you to create the remaining circuits. Repeat Steps 7 through 17 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 19
In the Circuits window, verify that the circuits you created appear in the circuits list.

Step 6
Click Next.
Step 7
Define the circuit attributes:
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
Size—Choose the optical circuit size. If you are creating an VC high-order path circuit, the choices are VC4, VC4-2c, VC4-3c, or VC4-4c. If you are creating a VC low-order path circuit, Size displays VC-12. You cannot change it.
•
Bidirectional—Leave the default (checked) for this circuit.
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. Also, VC low-order path tunnels and Ethergroup sources and destinations are unavailable.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–
unlocked—Puts the circuit cross-connects in the unlocked-enabled service state.
–
locked, outOfGroup—Puts the circuit cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the circuit cross-connects in the unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to unlocked-enabled.
–
locked, maintenance—Puts the circuit cross-connects in the locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use locked, maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; Automatic In Service; or locked, outOfGroup when testing is complete. See the "DLP-H111 Change a Circuit Service State" task.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15310-MA SDH Reference Manual.

Step 13
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.
Step 14

Step 1
Complete the "DLP-H29 Log into CTC" task at the node where you will create the VCAT circuit. If you are already logged in, continue with Step 2.
Step 2
Complete the following as necessary (you can provision Ethernet or POS ports before or after the VCAT circuit is created):
•
To provision Ethernet ports for CE-100T-8 or CE-MR-6 circuits, complete the "DLP-H190 Provision CE-100T-8 and CE-MR-6 Card Ethernet Ports" task.
•
To provision POS ports for CE-100T-8 or CE-MR-6 circuits, complete the "DLP-H191 Provision CE-100T-8 and CE-MR-6 Card POS Ports" task.
•
To provision a VCAT circuit that traverses through a third-party network, complete the "NTP-H140 Create a Server Trail" procedure.
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, choose VC_HO_Path_Circuit or VC_LO_Path_Circuit or any other circuit type from the Circuit Type drop-down list.
Step 6
Click Next.
Step 7
Define the circuit attributes:
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
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 the administrative state to apply to all of the member cross-connects in a VCAT circuit:
–
unlocked—Puts the member cross-connects in the unlocked-enabled service state.
–
locked, outOfGroup—Puts the member cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the member cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (unlocked-disabled,automaticInService) service state. When the connections receive a valid signal, the cross-connect service states automatically change to unlocked-enabled.
–
locked, maintenance—Puts the member cross-connects in the locked-enabled,maintenance service state. This service state does not interrupt traffic flow and allows loopbacks to be performed on the circuit, but suppresses alarms and conditions. Use the locked, maintenance administrative state for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; OOS; or Automatic In Service when testing is complete.
–
locked, outOfGroup—(LCAS only) Puts VCAT member cross-connects in the Out-of-Service and Management, Out-of-Group (locked-enabled,outOfGroup) service state. This administrative state is used to put a member circuit out of the group and to stop sending traffic. locked-enabled,outOfGroup applies only to the cross-connects on an end node where VCAT resides. The cross-connects on intermediate nodes are in the locked-enabled,maintenance service state.
•
Apply to drop ports—Check this check box to apply the unlocked 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 is 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 unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to unlocked-disabled,FLT.
•
Symmetric—Checked is the default. You cannot change it.
•
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 15310-MA SDH 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 15310-MA SDH Reference Manual.
Note
When creating open-ended VCAT circuits the number of members must be the same on each side of the virtual concatenated group (VCG). The configuration with different number of members on each side of circuit is not supported. This is applicable to circuits created on CE-Series and ML-Series cards.
•
Mode—Choose the protection mode for the VCAT circuit:
–
None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail. For CE-100T-8 and CE-MR-6 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 ML-100T-8 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 provides interoperability with the ONS 15454 ML-Series cards. Sw-LCAS uses legacy SDH failure indicators like AIS-P and RDI-P to detect member failure. You cannot add or delete members from a VCAT circuit with Sw-LCAS protection.
Note
While deleting SW-LCAS circuit members change the administrative state of the members to Locked,disabled. This is applicable to circuits created on CE-Series and ML-Series cards.
–
LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of noninvolved 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 mode for CE-100T-8 and ML-100T-8 cards that do not need to interoperate with the ONS 15454 ML-Series cards.
Note
For the CE-MR-10 card, before you create a VCAT circuit in the LCAS protection mode, it is recommended that you move all members of the VCAT circuit being created to Locked,OutOfGroup service state and then move them to Unlocked state.
Note
While deleting HW-LCAS circuit members change the administrative state of the members to Locked, OutOfGroup. This is applicable to circuits created on CE-Series and ML-Series cards.
Step 8
Click Next.
Step 9
Complete the "DLP-H65 Provision a VCAT Circuit Source and Destination" task for the VCAT circuit that you are creating.
Step 10
In the VCAT Circuit Routing Preferences area, 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.
Step 11
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.
Step 12
If you want to set preferences for individual members, complete the following in the Member Preferences area. To set identical preferences for all members, skip this step and continue with Step 13.
•
Number—Choose a number 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—(Future use) Routes the member on a bidirectional line switched ring (MS-SPRing) protection channel.
Note
Although ONS 15310-MA SDH does not support MS-SPRing, you can route an LCAS VCAT circuit over a MS-SPRing network of ONS 15600s or ONS 15454s.
–
DRI—(Split routing only) Routes the member on a DRI circuit.
•
Node-Diverse Path—(Split routing only) Available for each member when Fully Protected is chosen.
Step 13
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—(Future use) Routes the member on a MS-SPRing protection channel.
–
DRI—(Split routing only) Routes the member on a DRI circuit.
•
Node-Diverse Path—(Split routing only) Available when Fully Protected is chosen.
Step 14

Step 3
Complete the following as necessary (you can provision Ethernet or POS ports before or after the VCAT circuit is created):
•
To provision Ethernet ports for CE-100T-8 or CE-MR-6 circuits, complete the "DLP-H190 Provision CE-100T-8 and CE-MR-6 Card Ethernet Ports" task.
•
To provision POS ports for CE-100T-8 or CE-MR-6 circuits, complete the "DLP-H191 Provision CE-100T-8 and CE-MR-6 Card POS Ports" task.
•
To provision a VCAT circuit that traverses through a third-party network, complete the "NTP-H140 Create a Server Trail" procedure.
Step 4
From the View menu, choose Go to Network View.
Step 5
In the Circuit Creation dialog box, choose VC_HO_Path_Circuit or VC_LO_Path_Circuit or any other circuit type from the Circuit Type drop-down list.
Step 6
Click Next.
Step 7
Define the circuit attributes:
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
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 the administrative state to apply to all of the member cross-connects in a VCAT circuit:
–
unlocked—Puts the member cross-connects in the unlocked-enabled service state.
–
locked, outOfGroup—Puts the member cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Automatic In Service—Puts the member cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (unlocked-disabled,automaticInService) service state. When the connections receive a valid signal, the cross-connect service states automatically change to unlocked-enabled.
–
locked, maintenance—Puts the member cross-connects in the locked-enabled,maintenance service state. This service state does not interrupt traffic flow and allows loopbacks to be performed on the circuit, but suppresses alarms and conditions. Use the locked, maintenance administrative state for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; OOS; or Automatic In Service when testing is complete.
–
locked, outOfGroup—(LCAS only) Puts VCAT member cross-connects in the Out-of-Service and Management, Out-of-Group (locked-enabled,outOfGroup) service state. This administrative state is used to put a member circuit out of the group and to stop sending traffic. locked-enabled,outOfGroup applies only to the cross-connects on an end node where VCAT resides. The cross-connects on intermediate nodes are in the locked-enabled,maintenance service state.
•
Apply to drop ports—Check this check box to apply the unlocked 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 is 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.
•
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 15310-MA SDH Reference Manual.
•
Num. of members—Choose the number of members from the drop-down list. For information about the number of members supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15310-MA SDH Reference Manual.
Note
When creating open-ended VCAT circuits the number of members must be the same on each side of the virtual concatenated group (VCG). The configuration with different number of members on each side of circuit is not supported. This is applicable to circuits created on CE-Series and ML-Series cards.
•
Mode—Choose the protection mode for the VCAT circuit:
–
None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail. For CE-100T-8 or CE-MR-6, 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 ML-100T-8 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 provides interoperability with the ONS 15454 ML-Series cards. Sw-LCAS uses legacy SDH failure indicators like AIS-P and RDI-P to detect member failure. You cannot add or delete members from a VCAT circuit with Sw-LCAS protection.
Note
While deleting SW-LCAS circuit members change the administrative state of the members to Locked,disabled. This is applicable to circuits created on CE-Series and ML-Series cards.
–
LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of noninvolved 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 and ML-100T-8 cards that do not need to interoperate with the ONS 15454 ML-Series cards.
Note
For CE-MR-6 card, before you create a VCAT circuit in the LCAS protection mode, it is recommended that you move all members of the VCAT circuit being created to Locked,OutOfGroup service state and then move them to Unlocked state.
Note
While deleting HW-LCAS circuit members change the administrative state of the members to Locked, OutOfGroup. This is applicable to circuits created on CE-Series and ML-Series cards.

–
Fully Protected—Routes the circuit on a protected path.
–
Unprotected—Creates an unprotected circuit.
–
PCA—(Future use) Routes the member on a MS-SPRing protection channel.
Note
Although ONS 15310-MAs do not support MS-SPRing, you can route an LCAS VCAT circuit over a MS-SPRing network of ONS 15600s or ONS 15454s.
–
DRI—(Split routing only) Routes the member on a DRI circuit.
•
Node-Diverse Path—(Split routing only) Available for each member when Fully Protected is chosen.
Step 13
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.

Step 1
Complete the "DLP-H29 Log into CTC" taskat the node where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2
To assign a name to the circuit source and destination ports, complete the "DLP-H56 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 4.
Step 3
To provision the CE-MR-10 card, complete the "NTP-H154 Install the Ethernet Cards" task.
Step 4
From the View menu, choose Go to Network View.
Step 5
Click the Circuits tab, then click Create.
Step 6
In the Circuit Creation dialog box, choose the following:
•
Circuit Type—Choose VC_LO_PATH_CIRCUIT.
•
Number of Circuits—Enter the number of circuits that you want to create. The default is 1. Leave the default unchanged (1).
•
Auto-ranged—Unavailable when the Number of Circuits field is 1.
Step 7
Click Next.
Step 8
Define the circuit attributes:
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
Size—Choose VC3.
•
Bidirectional—Uncheck this to create a unidirectional circuit.
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this check box, low-order tunnels and Ethergroup sources and destinations are unavailable.
•
State—Choose the administrative state to apply to all cross-connects in a circuit:
–
Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
–
Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.
–
Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.
–
Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-H111 Change a Circuit Service State" task.
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15310-MA SDH Reference Manual.
•
Apply to drop ports—Check this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth. 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 check box is unchecked, CTC does not change the state of the source and destination ports.
Note
If ports in Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the service state of ports change to Unlocked-disabled,failed.
•
Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC displays only protected cards as source and destination choices.
Step 9
Click Next.
Step 10
Complete the "DLP-H63 Provision an STM-M Circuit Source and Destination" task.
Step 11
Uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.
Step 12
Set the circuit path protection:
•
To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
•
To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 14.
Step 13
If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP, choose one of the following:
•
Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring portions of the complete circuit path are nodally diverse.
•
Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.
•
Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.
Step 14
Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.
Step 15
Select the spans and click Add Span.
Step 16
Click Finish. The Circuits window appears.
Step 17
In the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and Search buttons become active.
Step 18
Click Edit (or double-click the circuit row). The Edit Circuit window appears with the General tab selected.
All nodes in the DCC network appear on the network. Circuit source and destination information appears under the source and destination nodes. To see a detailed view of the circuit, click Show Detailed Map. To rearrange a node icon, select the node, press Ctrl, then drag and drop the icon to the new location.
Step 19
In the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 20
Click Create.
Step 21
In the Define New Drop dialog box, create the new drop:
a.
Node—Choose the target node for the circuit drop.
b.
Slot—Choose the target card and slot.
c.
Port, VC4, or VC3—Choose the Port, VC4, or VC3 from the Port, VC4, or VC3 drop-down lists. The card selected in Step b determines the fields that appear. See Table 5-3for a list of options.
d.
The routing preferences for the new drop match those of the original circuit. However, you can modify the following:
•
If the original circuit was routed on a protected SNCP path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 13 for descriptions.
•
If the original circuit was not routed on a protected path, the Protection Channel Access option is available. See Step 12 for a description of the Protection Channel Access option.
e.
Click OK. The new drop appears in the Drops list.
Step 22
If you need to create additional drops for the circuit, repeat Step 21a through e to create the additional drops.
Step 23
Choose Close. The Circuits window appears.
Step 24
Verify that the new drops appear in the Destination column for the circuit that you edited. If they do not appear, repeat Step 21a through e, making sure that all options are provisioned correctly.
Stop. You have completed this procedure.
