Chapter 5 Create Circuits and VC Low-order Path Tunnels
Before You Begin
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 13 . CTC creates a fully protected circuit route based on the path diversity option you choose.
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 Step 15 .
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection
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 Step 12 and the circuit will be routed on a path protection DRI,
check the Dual Ring Interconnect check box.
Step 15
If you selected Using Required Nodes/Spans in Step 11 , complete the following substeps; otherwise,
continue with Step 17 :
a. Click Next .
b.
In the Circuit Route Constraints area, click a node or span on the circuit map.
c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span
from the circuit. The order in which you choose included nodes and spans determines the circuit
sequence. Click spans twice to change the circuit direction.
d.
Repeat Step c for each node or span you want to include or exclude.
e. Review the circuit route. To change the circuit routing order, choose a node from the Required
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.
Note If a node or span stays gray, that node or span is required.
Step 16 If you are creating a VC high-order path circuit, skip this step and continue with Step 17 . If you are
creating a VC low-order path circuit, click Next and complete the “DLP-H59 Provision VC high-order
path and VC Low-order Path Grooming Nodes” task on page 16-77 .
Step 17
If you selected Review Route Before Creation in Step 11 , complete the following substeps; otherwise,
continue with Step 18 .
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 the circuit information. If the circuit needs to be routed to a different path, see the
“NTP-H41 Create a Manually Routed DS-3 or E3 Circuit” procedure on page 5-18 .
