Chapter 5 Create Circuits and VC Low-order Path Tunnels
Before You Begin
Step 9
Complete the “DLP-H65 Provision a VCAT Circuit Source and Destination” task on page 16-82 for the
VCAT circuit that you are creating.
Step 10 In the VCAT Circuit Routing Preferences area, check Route Automatically . Two options are available;
choose either, both, or none based on your preferences.
•
Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or
exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path
of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans
are not in the working or protect path of the circuit.
•
Review Route Before Creation—Check this check box to review and edit the circuit route before the
circuit is created.
Step 11 Choose one of the following routing types:
•
Common Routing—Routes the members on the same fiber.
• Split Routing—Allows the individual members to be routed on different fibers or each member to
have different routing constraints. Split routing is required when creating circuits over a path
protection configuration.
Step 12
If you want to set preferences for individual members, complete the following in the Member
Preferences area. To set identical preferences for all members, skip this step and continue with
Step 13 .
• Number—Choose a number from the drop-down list to identify the member.
•
Name—Type a unique name to identify the member. The name can be alphanumeric and up to
48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the
circuit.
• Protection—Choose the member protection type:
–
Fully Protected—Routes the circuit on a protected path.
– Unprotected—Creates an unprotected circuit.
–
PCA—(Future use) Routes the member on a bidirectional line switched ring (MS-SPRing)
protection channel.
Note
Although ONS 15310-MA SDH does not support MS-SPRing, you can route an LCAS
VCAT circuit over a MS-SPRing network of ONS 15600s or ONS 15454s.
–
DRI—(Split routing only) Routes the member on a DRI circuit.
• Node-Diverse Path—(Split routing only) Available for each member when Fully Protected is
chosen.
Step 13
To set preferences for all members, complete the following in the Set Preferences for All Members area:
• Protection—Choose the member protection type:
–
Fully Protected—Routes the circuit on a protected path.
– Unprotected—Creates an unprotected circuit.
–
PCA—(Future use) Routes the member on a MS-SPRing protection channel.
– DRI—(Split routing only) Routes the member on a DRI circuit.
•
Node-Diverse Path—(Split routing only) Available when Fully Protected is chosen.
