Before You Begin
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
•
If you selected Fully Protected Path in
Step 13
configuration, choose 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.
Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path
•
protection portions of the complete circuit path are needed. The paths might be node-diverse, but
CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in
check the Dual Ring Interconnect check box.
If you selected Using Required Nodes/Spans in

a.
In the Circuit Route Constraints area, click a node or span on the circuit map.
b.
Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span
c.
from the circuit. The order in which you choose included nodes and spans is the order in which the
circuit will be routed. Click spans twice to change the circuit direction.
Repeat Step
d.
Review the circuit route. To change the circuit routing order, choose a node in the Required
e.
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.
If you are creating an VC high-order path circuit, skip this step and continue with
Step 16
creating a VC low-order path circuit, click Next and complete the

Step 17 If you selected Review Route Before Creation in
continue with
a. Click Next.
b. Review the circuit route. To add or delete a circuit span, choose 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.
If the provisioned circuit does not reflect the routing and configuration you want, click Back to
c.
verify and change the circuit information. If the circuit needs to be routed to a different path, see the
"NTP-H48 Create a Manually Routed Optical Circuit" procedure on page 5-35
route yourself.
Click Finish. One of the following results occurs, based on the circuit properties you provisioned in the
Step 18
Circuit Creation dialog box:
If you entered 1 in the Number of Circuits field, CTC creates the circuit.
