DLP-A398 Automatically Route a Path Protection Circuit for a Topology Upgrade
Step 3 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 4 If you selected VT-DS3 Mapped Conversion in Step 2, complete the following substeps; otherwise,
continue with Step 5:
a. Click Next.
b. In the Conversion Circuit Route Constraints area, complete the following:
• Node—Choose a node with a DS3XM-12 card installed.
• Slot—Choose the slot where a DS3XM-12 card is installed.
• DS3 Mapped STS—If applicable, choose Circuit Dest to indicate that the STS is the circuit
destination, or Circuit Source to indicate that the STS is the circuit source.
Step 5 If you selected Review Route Before Creation in Step 2, complete the following substeps. If not,
continue with Step 6.
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.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to
verify and change circuit information. If the circuit needs to be routed to a different path, see the
“NTP-A182 Create a Manually Routed DS-1 Circuit” procedure on page 6-11.
Step 6 Click Finish.
Step 7 Return to your originating procedure (NTP).
