DLP- F351 Roll the Source or Destination of One Optical Circuit

Step 11 Click the Rolls tab (Figure 18-15). For the pending roll, view the Roll Valid Signal status. When one of the following conditions are met, continue with Step 12.

•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 ONS 15600 SDH Troubleshooting Guide. To cancel the roll, see the “DLP-F357 Cancel a Roll” task on page 18-70.

•The roll is a one-way destination roll and the Roll Valid Signal is false. It is not possible to get a Roll Valid Signal status of true for a one-way destination roll.

Note You cannot cancel an automatic roll after a valid signal is found.

•You can force a signal onto the Roll To circuit by using the Force Valid Signal button. If you choose Force Valid Signal, traffic on the circuit that is involved in the roll might drop depending on conditions at the other end of the circuit when the roll is completed. You must force a signal if the circuits do not have a signal or have a bad signal and you want to complete the roll.

Note For a one-way destination roll in manual mode, you do not need to force the valid signal.
