Circuit Routing Preferences


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

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.

VT-DS3 Mapped Conversion

If checked, creates the circuit on a pair of portless transmux (ONS 15454 DS3XM-12) cards.

Fully Protected Path

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 unidirectional path switched ring (UPSR) path segments (with primary and alternate paths), and the path diversity options apply only to UPSR path segments, if any exist.

Nodal Diversity Required

Ensures that the primary and alternate paths within UPSR portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired

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.

Link Diversity Only

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

If Fully Protected Path is not checked and the circuit is routed on a bidirectional line switched ring (BLSR), click this check box to route the circuit on a BLSR protection channel. Circuits routed on protection channel access (PCA) are unprotected.

Dual Ring Interconnect

If Fully Protected Path is not checked and the circuit is routed on a UPSR or BLSR dual-ring interconnect (DRI), clicking this check box routes the circuit on the DRI.
