Chapter 6 Create Circuits and Low-Order Tunnels
NTP- D324 Create a Manually Routed High-Order Circuit
• To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.
• To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected
Path, check Protection Channel Access, click Ye s in the Warning dialog box, then continue with
Step 16.
Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during
MS-SPRing switches.
Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP, choose one of
the following:
• Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring
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 SNCP ring portion of the complete circuit path.
• Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring
portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not
check for node diversity.
Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an MS-SPRing DRI or
SNCP DRI, click the Dual Ring Interconnect check box.
Step 16 Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If
you checked Dual Ring Interconnect for MS-SPRing, continue with Step 17. If not, continue with
Step 18.
Step 17 If you checked Dual Ring Interconnect in Step 13 for a MS-SPRing DRI, complete the following
substeps to assign primary and secondary nodes.
a. In the Route/Review Edit area, click the MS-SPRing DRI Nodes tab.
b. Click Add MS-SPRing DRI.
c. In the Node Options area of the MS-SPRing DRI Options dialog box, complete the following:
• Primary Node—For a traditional or integrated MS-SPRing DRI, choose the node where the
circuit interconnects the rings.
• Secondary Node—For a traditional or integrated MS-SPRing DRI, choose the secondary node
for the circuit to interconnect the rings. This route is used if the route on the primary node fails.
• Primary Node #2—For a traditional MS-SPRing DRI where two primary nodes are required to
interconnect rings, choose the second primary node.
• Secondary Node #2—For a traditional MS-SPRing DRI where two secondary nodes are
required, choose the second secondary node.
d. Click OK.
e. Review the circuit constraints. To change the circuit routing order, choose a node in the
Required Nodes/Lines lists and click the Up or Down buttons to change the circuit routing order.
Click Remove to remove a node or span.
f. Click the Included Spans tab, and continue with Step 18.
Step 18 Complete the “DLP-D98 Provision a High-Order Circuit Route” task on page 17-96.
