which you want to roll traffic and click OK.
If multiple Roll From paths do not exist, continue with

The circuit status for the Roll From path changes from DISCOVERED to ROLL PENDING.
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.
If the termination card is a DS3i-N-12, E1-N-14, E1-42 or E3-12 card, a roll will occur even if a valid

signal is not detected on the Roll To port. The absence of PDI-P downstream for LOS, LOF, and AIS line
defects causes the roll to continue without a valid signal. This is only seen with DUAL roll mode when
both ends of the circuit use the card(s) listed in this statement.
Click Finish. In the Circuits tab, the Roll From and Roll To circuits change from the DISCOVERED

status to ROLL PENDING.
Step 13 Click the Rolls tab. Two new rolls now appear on the Rolls tab. For each pending roll, view the Roll Valid
Signal status. When one of the following conditions is met, continue with
• 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 Circuits and Timing
section of the Cisco ONS 15454 SDH Troubleshooting Guide. To cancel the roll, see the
Cancel a Roll" task on page
The roll is a one-way destination roll and the Roll Valid signal status is false. It is not possible to
•
get a Roll Valid Signal status of true for a one-way destination roll.
Note
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 when the roll is completed.

You cannot cancel an automatic roll after a valid signal is found.
Step 5, click both rolls on the Rolls tab and click Complete to route the traffic
You cannot complete a roll if you cancelled the sibling roll. You must complete the two rolls
