Use the Circuit Routing Preferences page to provision the roll routing parameters. The following table
describes the Circuit Routing Preferences page fields and buttons.

|
|
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.
|
|
(Unavailable for roll creation) If checked, creates the circuit on a pair of portless transmux (ONS 15454 DS3XM-12) cards .
|
|
(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 UPSR path segments (with primary and alternate paths), and the path diversity options apply only to UPSR path segments, if any exist.
|
|
(Unavailable for roll creation) Ensures that the primary and alternate paths within UPSR portions of the complete circuit path are nodally diverse.
|
|
(Unavailable for roll creation) Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the UPSR portion of the complete circuit path.
|
|
(Unavailable for roll creation) Specifies that only fiber-diverse primary and alternate paths for UPSR 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 a BLSR, click this check box to route the circuit on a BLSR protection channel. Circuits routed on PCA channels are unprotected.
|
|
(Unavailable for roll creation) If Fully Protected Path is not checked and the circuit is routed on a UPSR or BLSR-DRI, clicking this check box routes the circuit on the DRI.
