Step 6
Click Next.
Step 7 In the Pivot/Fixed Point 1 window, click the square representing the fixed path of the first connection to
be rolled (Figure 19-6 on page 19-32).
This path is a fixed point in the cross-connect involved in the roll process. The path identifier appears in
the text box below the graphic image. The path that is not selected contains the Roll From path. The Roll
From path is deleted after the roll is completed.
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
(Figure 19-11). 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.
