NTP-A314 Create a Unidirectional OC-N Circuit with Multiple Drops
Figure 6-13
Setting Circuit Attributes for a Unidirectional OC-N Circuit
Step 8
If the circuit will be routed on a path protection, complete the
“DLP-A218 Provision Path Protection
.
Step 9
Click
Next
.
Step 10
Complete the
“DLP-A97 Provision an OC-N Circuit Source and Destination” task on page 17-98
for the
circuit you are creating.
Step 11
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
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
. 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
•
To route the circuit on a BLSR 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 BLSR protection channels are not protected and are preempted during BLSR
switches.
Step 13
If you selected Fully Protected Path in
and the circuit will be routed on a path protection, choose
one of the following:
•
Nodal Diversity Required—Ensures that the primary and alternate paths within the 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.
