available; choose 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.
• VT-DS3 Mapped Conversion—Check this check box to create a circuit using the portless
transmultiplexing interface of the DS3XM-12 card.

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
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
•
To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path,
•
check Protection Channel Access, click Yes in the Warning dialog box, then continue with
If you selected Fully Protected Path in
Step 13
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.
