Complete the

for the high-order circuit you are creating.
In the Circuit Routing Preferences area, choose Route Automatically. Two options are available;
Step 13
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.
Set the circuit path protection:
Step 14
To route the circuit on a protected path, leave Fully Protected Path checked and continue with
•
Step
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
•
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, then continue with
Step
If you selected Fully Protected Path in
Step 15
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.
