Step 8
Click Next .
Step 9 Complete one of the following:
•
If multiple Roll From paths exist, the Select Roll From dialog box appears. Select the path from
which you want to roll traffic and click
OK .
• If multiple Roll From paths do not exist, continue with Step 10 . The circuit status for the Roll To
path changes states from DISCOVERED to ROLL_PENDING.
Step 10
In the Pivot/Fixed Point 2 window, click the square that represents the fixed path of the second
connection to be rolled.
The path that is not selected is the Roll From path. The Roll From path is deleted after the roll is
completed. The path identifier appears in the text box below the graphic image.
Step 11
Click Next .
Step 12 In the Circuit Routing Preferences area, check Route Automatically to allow CTC to find the route. If
you check Route Automatically, the following options are available:
•
Using Required Nodes/Spans—If checked, you can specify nodes and spans to include or exclude
in the CTC-generated circuit route in
Step 15 .
• Review Route Before Creation—If checked, you can review and edit the circuit route before the
circuit is created.
Step 13
To route the circuit over a protected path, check Fully Protected Path . (If you do not want to route the
circuit on a protected path, continue with Step 14 .) CTC creates a primary and alternate circuit route
(virtual path protection) based on the following nodal diversity options. Select one of the following
choices and follow subsequent window prompts to complete the routing:
• Nodal Diversity Required—Ensures that the primary and alternate paths within extended SNCP
portions of the complete circuit path are nodally diverse.
•
Nodal Diversity Desired—Specifies that node diversity should be attempted, but if node diversity is
not possible, CTC creates link diverse paths for the Extended SNCP portion of the complete circuit
path.
• Link Diversity Only—Specifies that only link-diverse primary and alternate paths for Extended
SNCP portions of the complete circuit path are needed. The paths might be node-diverse, but CTC
does not check for node diversity.
Step 14
If you checked Route Automatically in Step 12 :
• If you checked Using Required Nodes/Spans, continue with Step 15 .
•
If you checked only Review Route Before Creation, continue with Step 16 .
• If you did not check Using Required Nodes/Spans or Review Route Before Creation, continue with
Step 17 .
Step 15
If you checked Using Required Nodes/Spans in Step 12 :
a. In the Roll Route Constraints area, click a node or span on the circuit map.
b.
Click Include to include the node or span in the circuit. Click Exclude to exclude the node/span
from the circuit. The order in which you select included nodes and spans sets the circuit sequence.
Click spans twice to change the circuit direction.
c. Repeat Step b for each node or span you wish to include or exclude.
d.
Review the circuit route. To change the circuit routing order, select a node in the Required
Nodes/Lines or Excluded Nodes Links lists, then click the
Up or Down buttons to change the circuit
routing order. Click Remove to remove a node or span.
