Figure 5-5 Setting Circuit Routing Preferences For A Ds-3 Circuit - Cisco ONS 15327 Procedure Manual

NTP-B184 Create an Automatically Routed DS-3 Circuit
Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or
•
exclude in the CTC-generated circuit route.
Review Route Before Creation—Check this check box to review and edit the circuit route before the
•
circuit is created.
Set the circuit path protection:
Step 10
To route the circuit on a protected path, leave Fully Protected Path checked and continue with
•
Step
Fully-protected paths may or may not have path protection segments (with primary and alternate
paths), and the path diversity options apply only to path protection 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 on the Warning dialog box, and then continue with
Step
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR
Caution
switches.
If you selected Fully Protected Path in
Step 11
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 may be node-diverse, but CTC
does not check for node diversity.

interconnect (DRI), check the Dual Ring Interconnect check box.
