VCAT Circuit Routing Preferences
(ONS 15454 SDH only) Use the VCAT Circuit Routing Preferences page to provision the VCAT circuit routing parameters. The following table describes the VCAT Circuit Routing Preferences page fields and buttons.
 
Item
Description
Route Automatically
If checked, CTC routes the VCAT circuit automatically based on the parameters that you specify on this page.
Using Required Nodes/Spans
If checked, CTC allows you to choose nodes and spans to include in the automatically routed VCAT circuit path before circuit completion.
Review Route Before Creation
If checked, CTC allows you to review and modify the VCAT circuit route before circuit creation.
Common Fiber Routing
If chosen, CTC routes the VCAT circuit members on the same fiber.
Split Routing
If chosen, CTC routes the VCAT circuit members on different fibers.
Use Extended Buffer
(Display only; FC_MR-4 card only) When Split Routing is chosen, differential delay is enabled and this box is automatically selected. If Common Fiber Routing is chosen, differential delay is disabled, and the Use Extended Buffer check box is automatically deselected.
Member Preferences
Provisions the protection for individual VCAT circuit members. Valid entries are:
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: Routes the member on an MS-SPRing protection channel.
DRI: (Split routing only) Routes the member on a dual ring interconnect circuit.
Node-Diverse Path: (Split routing only) Available for each member when Fully Protected is chosen.
Note
If a member is unprotected, all members must be unprotected.
Set Preferences for All Members
Set preferences for all members in a VCAT circuit:
Protection: Choose the member protection type:
Fully Protected: Routes the circuit on a protected path.
Unprotected: Creates an unprotected circuit.
PCA: Routes the member on a MS-SPRing protection channel.
DRI: (Split routing only) Routes the member on a dual ring interconnect circuit.
Node-Diverse Path: (Split routing only) Available when Fully Protected is choose.
