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.
Set the circuit path protection:
Step 13
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, and then continue
with
Circuits routed on MS-SPRing protection channels are not protected. They are preempted during

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.
• 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.

circuit is routed. Click spans twice to change the circuit direction.
Repeat Step c for each node or span that you wish to include or exclude.
