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 From path changes 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 .
Caution
The following is only seen with DUAL roll mode when both ends of the circuit use the port mentioned
in this statement. If the termination port is the E1 port, 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. On the E1 port it is possible to check the Send AIS-V
For E1 AIS check box to properly generate PDI-P downstream for the LOS and LOF AIS line defects.
This check box is selected from the card view, Provisioning > Line tabs. On the E1 port, Send AIS-V for
E1 AIS only works for VC low-order path circuits.
Step 12
Click Finish . In the Circuits tab, the Roll From and Roll To circuits change from the DISCOVERED
status to ROLL RENDING.
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 are met, continue with Step 14 .
•
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. To cancel the roll, see the
“DLP-H189 Cancel a Roll” task on
page 17-84 .
•
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
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.
Step 14 If you selected Manual in Step 5 , click both rolls on the Rolls tab and click Complete to route the traffic
to the new port. If you selected Auto, continue with Step 15 .
Note
You cannot complete a roll if you cancelled the sibling roll. You must complete the two rolls
together.
Step 15
For both manual and automatic rolls, click Finish to complete the circuit roll process.
