Setting Circuit Attributes for a Unidirectional Low-Order VC3 Circuit
Step 9
Click

.
Step 10
Complete the
“DLP-D318 Provision a Low-Order VC3 Circuit Source and Destination” task on
Step 11
In the Circuit Routing Preferences area, uncheck
Route Automatically
. When Route Automatically is
not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes
are unavailable.
Step 12
Set the circuit path protection:
•
To route the circuit on a protected path, leave Fully Protected Path checked and continue with
. 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, then continue with
Caution
Circuits routed on MS-SPRing protection channels are not protected and are preempted during
MS-SPRing switches.
Step 13
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 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 14
If you selected Fully Protected Path in
and the circuit will be routed on an SNCP DRI, click the
Dual Ring Interconnect
check box.
