Roll Creation Circuit Routing Preferences
Use the Circuit Routing Preferences page to provision the roll routing parameters. The following table describes the Circuit Routing Preferences page fields and buttons.
 
Item
Description
Route Automatically
If checked, CTC routes the 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 circuit path before circuit completion.
Review Route Before Creation
If checked, CTC allows you to review and modify the circuit route before circuit creation.
Fully Protected Path
(Unavailable for roll creation) If checked, CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.
Nodal Diversity Required
(Unavailable for roll creation) Ensures that the primary and alternate paths within SNCP portions of the complete circuit path are nodally diverse.
Nodal Diversity Desired
(Unavailable for roll creation) Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP portion of the complete circuit path.
Link Diversity Only
(Unavailable for roll creation) Specifies that only fiber-diverse primary and alternate paths for SNCP portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Protection Channel Access
(Unavailable for roll creation) If Fully Protected Path is not checked and the circuit is routed on an MS-SPRing, click this check box to route the circuit on an MS-SPRing protection channel. Circuits routed on PCAs are unprotected.
Dual Ring Interconnect
(Unavailable for roll creation) If Fully Protected Path is not checked and the circuit is routed on an SNCP or MS-SPRing-DRI, clicking this check box routes the circuit on the DRI.
Back
Displays the previous roll creation page. The page that appears depends on the circuit type and provisioning.
Next
Displays the next roll creation page.
Finish
Creates the roll. After the roll is created, if you have rolled to an unprotected circuit, it will appear in red.
Cancel
Cancels roll creation.
Help
Displays context-sensitive help.
