Create Circuits
This chapter explains how to create CiscoONS15600SDH circuits. For additional information, refer to the Circuits chapter in the CiscoONS15600SDH Reference Manual.
Note 
The Software Release 1.4 does not support a full state model. As a result, the circuit state cannot be changed; it is always In Service (IS).
Before You Begin
Before performing any of the following procedures, investigate all alarms and clear any trouble conditions. Refer to the CiscoONS15600SDH Troubleshooting Guide as necessary.
This section lists the chapter procedures (NTPs). Turn to a procedure for a list of its tasks (DLPs).
1. F41 Verify Network Turn Up—Complete this procedure before you create any circuits.
2. F42 Create an Automatically Routed Optical Circuit—Complete as needed.
3. F43 Create a Manually Routed Optical Circuit—Complete as needed.
4. F44 Create a Unidirectional Optical Circuit with Multiple Drops—Complete this procedure as needed.
5. F45 Test Optical Circuits—Complete this procedure after you create circuits.
6. F46 Create a Half Circuit on an MS-SPRing or 1+1 (LMSP) Node—Complete this procedure as needed to create a half circuit using an STM-N as a destination in an multiplex section-shared protection ring (MS-SPRing) or 1+1 (LMSP) topology.
7. F47 Create a Half Circuit on an SNCP Node—Complete as needed to create a half circuit using an STM-N as a destination in a subnetwork connection protection (SNCP) node.
8. F48 Create a DCC Tunnel—Complete as needed.
Note To provision ONS15600SDH circuits from an ONS 15454 SDH node, the Cisco Transport Controller (CTC) version launched must be compatible with or higher than the ONS15600SDH CTC version.
Note In this chapter, "cross-connect" and "circuit" have the following meanings: cross-connect refers to the connections that occur within a single node to allow a circuit to enter and exit the node. Circuit refers to the series of connections from a traffic source (where traffic enters the network) to the drop or destination (where traffic exits the network).
Note You cannot set up low-order circuits to terminate on an ONS15600SDH node. However, you can create both high-order and low-order circuits that have an ONS 15454 SDH source and destination with an ONS15600SDH as a pass-through node. When creating a low-order path circuits between ONS15454SDH nodes, a VC4 tunnel is necessary. The VC4 tunnel can be created automatically by using the Circuit Creation wizard to create the low-order circuit, or manually by using the Circuit Creation wizard to create the VC4 tunnel before creating the low-order circuit. When you create VC4 tunnels over ONS 15600 pass-through nodes manually, you have control over how the tunnel is created. For information about low-order circuit creation and tunneling, refer to the circuit chapters in the Cisco ONS 15454 SDH Procedure Guide.
Note During circuit provisioning in a network that includes ONS 15600s and ONS 15454s, the ONS15600SDH raises a temporary UNEQ-P alarm. The alarm clears when the circuit is complete.
Table6-1 defines key ONS15600SDH circuit creation terms and options.
Table 6-1 Key ONS 15600 SDH Circuit Options
|
Circuit Option
|
Description
|
|
Source
|
The point where the circuit enters the ONS15600SDH network. The first facility specified when creating a connection is also considered the source.
|
|
Destination
|
The point where the circuit exits an ONS15600SDH network. The last facility specified when creating a connection is also considered the destination.
|
|
Automatic circuit routing
|
CTC routes the circuit automatically on the shortest available path based on the routing parameters that you define and on bandwidth availability.
|
|
Manual circuit routing
|
Allows you to choose a specific path, not just the shortest path chosen by automatic routing. You can choose a specific virtual channel (VC) for each circuit segment, and you can create circuits from work orders prepared by an operations support system (OSS) like the Telcordia TIRKS system.

Step1 Complete the "DLP-F36 Log into CTC" task at a node on the network where you will create circuits. If you are already logged in, continue with Step2.
Step2 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 ONS15600SDH network, the node icons will be stacked on the left side of the graphic area, possibly out of view. Use the scroll bar below the network map to display the icons. To separate the icons, press Ctrl and drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.
Step3 Verify node accessibility. All node icons must be either green, yellow, orange, or red.
If all network nodes do not appear after a few minutes, or if a node icon is gray with an IP address beneath 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 Discovery check box on the CTC Login dialog box. If problems persist, see "Turn Up Network" to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15600 SDH Troubleshooting Guide for troubleshooting procedures.
Step4 Verify data communications channel (DCC) connectivity. All nodes must be connected by green lines. If lines are missing or gray, do not continue. See "Turn Up Network" and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing.
Step5 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 CiscoONS15600SDH Troubleshooting Guide to resolve alarms before continuing.
Step6 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 displayed in the shelf map. Verify that the ONS 15600 SDH cards appear in the specified slots.
b. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and Simple Network Time Protocol (SNTP) server IP address (if used) are correctly provisioned. If needed, make corrections using the "NTP-F24 Set Up Date, Time, and Contact Information" procedure on page 4-6 .
c. Click the Network tab. Verify that the IP address, Subnet Mask, Default Router, and Gateway Settings are correctly provisioned. If not, make corrections using the "NTP-F25 Set Up CTC Network Access" procedure on page 4-8 .
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-F27 Create a 1+1 (LMSP) Protection Group" procedure on page 4-19 .
e. If the node is in an MS-SPRing, click the MS-SPRing tab. (If the node is not in an MS-SPRing, continue with Step f .) Verify that the following items are provisioned as specified in your site plan:
•MS-SPRing type (2-Fiber)
•MS-SPRing ring ID and node IDs
•Ring reversion time
•East and west card assignments
If you need to make corrections, see the "NTP-F36 Provision MS-SPRing 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-F23 Create Users and Assign Security" procedure on page 4-4 to correct the information.
g. If SNMP is used, click the SNMP tab and verify the trap and destination information. If the information is not correct, see the "NTP-F28 Set Up SNMP" procedure on page 4-21 to correct the information.
h. Click the DCC/GCC tab. Verify that DCCs were created to the applicable STM-N cards and ports. If DCCs were not created for the appropriate STM-N cards and ports, go to the "DLP-F53 Provision SDH DCC Terminations" task .
i. Click the Timing tab. Verify that timing is provisioned as specified. If not, go to the "NTP-F72 Change Node Timing" procedure to make the changes.
j. Click the Alarm Behavior tab. If you provisioned optional alarm profiles, verify that the alarms are provisioned as specified. If not, see the "NTP-F56 Create, Assign, and Delete Alarm Severity Profiles" procedure to change the information.
Step7 Repeat Step6 for each node in the network.
Step8 As appropriate, complete circuit creation procedures listed below:
• F42 Create an Automatically Routed Optical Circuit
• F43 Create a Manually Routed Optical Circuit
• F44 Create a Unidirectional Optical Circuit with Multiple Drops
• F46 Create a Half Circuit on an MS-SPRing or 1+1 (LMSP) Node

Step1 Complete the "DLP-F36 Log into CTC" task at a node on the network where you will create the high-order circuit. The default (node) view appears. If you are already logged in, continue with Step2.
Step2 If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-F60 Assign a Name to a Port" task. If not, continue with Step3.
Step3 From the View menu, choose Go To Network View .
Step4 Click the Circuits tab, then click Create .
Step5 In the Circuit Creation dialog box ( Figure6-1), complete the following fields:
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Type—Choose VC_HO_PATH_CIRCUIT .
•Size—Choose the circuit size: VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-16c, or VC4-64c.
•Bidirectional—When checked (default), creates a two-way circuit. Leave checked for this circuit.
•Number of circuits—Type the number of circuits you want to create. The default is 1. If you are creating multiple circuits with the same source and destination, you can use autoranging to create the circuits automatically.
•Auto-ranged—This box is automatically checked when you enter more than 1 in the Number of circuits field. Leave this box checked if you are creating multiple optical circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck the box if you do not want CTC to create the circuits automatically.
•State—Choose IS (CTC displays only in-service circuits).
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC will apply the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box displays the ports where the circuit state could not be applied. If the box is unchecked, CTC will not change the state of the source and destination ports.
Note Loss of Signal (LOS) alarms appear if in service (IS) ports are not receiving signals.
•Inter-domain (UCP) SLA—Future use.
•Protected Drops—Check this box if you want CTC to display only protected cards and ports (1+1 protection) as choices for the circuit source and destination.
Figure 6-1 Creating a Circuit
Step6 If the circuit will be routed on an SNCP, complete the "DLP-F61 Provision SNCP Selectors During Circuit Creation" task.
Step7 Click Next .
Step8 Complete the "DLP-F62 Provision an Optical Circuit Source and Destination" task for the optical circuit that you are creating.
Step9 In the Circuit Routing Preferences area ( Figure6-2), check Route Automatically . Two options are available; choose either, both, or none based on your preferences.
•Using Required Nodes/Spans—Check this box to specify nodes and spans to include or exclude in the CTC-generated circuit route.
•Review Route Before Creation—Check this box to review and edit the circuit route before the circuit is created.
Figure 6-2 Setting Circuit Routing Preferences
Step10 Set the circuit path protection:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 11 . CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths 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 12 .
•To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path , check Protection Channel Access , click Yes in the Warning dialog box, and then continue with Step 12 .
Caution Circuits routed on MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.
Step11 If you selected Fully Protected Path, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP 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 portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step12 If you selected Using Required Nodes/Spans in Step9, complete the following substeps; otherwise, proceed to Step13:
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 select included nodes and spans sets the circuit sequence. Click spans twice to change the circuit direction.
d. Repeat Step c for each node or span you wish to include or exclude.
e. Review the circuit route. To change the circuit routing order, select a node beneath 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.
Step13 If you selected Review Route Before Creation in Step9, complete the following substeps; otherwise, proceed to Step14:
a. Click Next .
b. Review the circuit route. To add or delete a circuit span, select 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-F43 Create a Manually Routed Optical Circuit" procedure to assign the circuit route yourself.
Step14 Click Finish. One of the following occurs, based on the circuit properties you provisioned in the Circuit Creation dialog box:
•If you entered more than 1 in Number of Circuits and checked Auto-ranged, CTC automatically creates the number of circuits entered in Number of Circuits. If autoranging cannot complete all the circuits (for example, not enough bandwidth is available 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.
•If you entered more than 1 in Number of Circuits and did not check Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 13 for each additional circuit.
•After completing the circuit(s), the Circuits window appears.
Step15 In the Circuits window, verify that the circuit(s) just created appear in the circuits list.
Step16 Complete the "NTP-F45 Test Optical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.
