Figure18-16 Selecting Roll Attributes for a Single Roll onto a Second Circuit
Step6 Click Next.
Step7 In the Pivot/Fixed Point 1 window, click the square representing the facility that you want to keep
(Figure 18-13 on page18-58).
This facility is the fixed location in the cross-connect involved in the roll process. The identifier appears
in the text box below the graphic image. The facility that is not selected is the Roll From path. The
Roll From path is deleted after the roll is completed.
Step8 Click Next.
Step9 In the Select New End Point area, choose the Slot, Port, and VC3 or VC4 from the drop-down lists to
identify the Roll To facility on the connection being rolled.
Step10 Click Finish.
The statuses of the Roll From and Roll To circuits change from DISCOVERED to ROLL_PENDING in
the Circuits tab.
Step11 Click the Rolls tab. For the pending roll, view the Roll Valid Signal status. When one of the following
conditions are met, continue with Step12.
•If the Roll Valid Signal status is true, a valid signal was found on the new port.
•If the Roll Valid Signal status is false, a valid signal was not found. Wait until the signal is found
before continuing with the next step. If the signal is not found, refer to the “General
Troubleshooting” chapter in the Cisco ONS15600 SDH Troubleshooting Guide. To cancel the roll,
see the “DLP-F357 Cancel a Roll” task on page18-70.
•The roll is a one-way destination roll and the Roll Valid Signal is false. It is not possible to get a
“true” Roll Valid Signal status for a one-way destination roll.
Note You cannot cancel an automatic roll after a valid signal is found.
•A roll can be forced onto the Roll To Circuit destination without a valid signal by using the Force
Valid Signal button. If you choose Force Valid Signal, traffic on the circuit that is involved in the
roll will be dropped once the roll is completed.
