Setting Circuit Routing Preferences
Step 13
Set the circuit path protection:
•
To route the circuit on a protected path, leave Fully Protected Path checked and continue with
. CTC creates a fully protected circuit route based on the path diversity option you choose.
Fully protected paths might or might not have SNCP path segments (with primary and alternate
paths), and the path diversity options apply only to SNCP path segments, if any exist.
•
To create an unprotected circuit, uncheck
Fully Protected Path
and continue with
•
To route the circuit on an MS-SPRing protection channel, if available, uncheck
Fully Protected
Path
,
check
Protection Channel Access
, click
Yes
in the Warning dialog box, and then continue
with
Caution
Circuits routed on MS-SPRing protection channels are not protected. They are preempted during
MS-SPRing switches.
Step 14
If you selected Fully Protected Path in
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 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
and the circuit will be routed on an SNCP DRI, check the
Dual Ring Interconnect
check box.
Step 16
If you selected Using Required Nodes/Spans in
, complete the following substeps. If not,
continue with
a.
Click
Next
.
b.
In the Circuit Route Constraints For Auto Routing area, click a node or span on the circuit map.
