Chapter 5 Create Circuits and VC Low-order Path Tunnels
Complete the
Step 9
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.
Choose one of the following routing types:
Step 11
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.
If you want to set preferences for individual members, complete the following in the Member
Step 12
Preferences area. To set identical preferences for all members, skip this step and continue with
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:
–
–
–
–
• 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:
–
–
–
–
Node-Diverse Path—(Split routing only) Available when Fully Protected is chosen.

"DLP-H65 Provision a VCAT Circuit Source and Destination" task on page 16-82
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.
Although ONS 15310-MA SDH does not support MS-SPRing, you can route an LCAS
Note
VCAT circuit over a MS-SPRing network of ONS 15600s or ONS 15454s.
DRI—(Split routing only) Routes the member on a DRI circuit.
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.
