Step 10
If the circuit will be routed on an SNCP ring, complete the “DLP-D218 Provision SNCP Ring Selectors
During Circuit Creation” task on page 19-17.
Step 11 Click Next.
Step 12 Complete the “DLP-D97 Provision a High-Order Circuit Source and Destination” task on page 17-95
for the high-order circuit you are creating.
Step 13 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 14 Set the circuit path protection:
• To route the circuit on a protected path, leave Fully Protected Path checked and continue with
Step 15. 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 17.
• To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected
Path, check Protection Channel Access, click Ye s in the Warning dialog box, then continue with
Step 17.
Step 15 If you selected Fully Protected Path in Step 14 and the circuit will be routed on SNCP, choose one of
the following:
• Nodal Diversity Required—Ensures that the primary and alternate paths within 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.
