Chapter 5 Create Circuits and VC Low-order Path Tunnels
Protected Drops—Check this check box if you want the circuit routed on protected drops only, that

is, to ports that are in 1+1 protection. If you check this check box, CTC displays only protected cards
and ports as source and destination choices.
If the circuit will be routed on a path protection configuration, complete the

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 a Node-Diverse Path option:
Nodal Diversity Required—Ensures that the primary and alternate paths within the 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.
If you selected Fully Protected Path in
Step 14
check the Dual Ring Interconnect check box.
If you are creating a VC high-order path circuit, skip this step and continue with
Step 15
creating a VC low-order path circuit, click Next and complete the

source node is selected. Green arrows pointing from the source node to other network nodes indicate
spans that are available for routing the circuit.
Complete the
Step 17
circuit that you are creating.
Step 18 Click Finish.
CTC compares your manually provisioned circuit route with the specified path diversity option you
chose in
error message and allows you to change the circuit path.
If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears for
Step 19
you to create the remaining circuits. Repeat Steps
When all the circuits are created, the main Circuits window appears. Verify that the circuits you created
