Step 16
If you checked Review Route Before Creation in Step 12 :
a. In the Roll Route Review and Edit area, review the circuit route. To add or delete a circuit span,
select a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans
that you can add. Click a span arrowhead, then click
Include to include the span or Remove to
remove the span.
b.
If the provisioned circuit does not reflect the routing and configuration you want, click Back to
verify and change circuit information.
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 17 Click Finish .
In the Circuits tab, verify that a new circuit appears. This circuit is the Roll To circuit. It is designated
with the Roll From circuit name appended with ROLL**.
Step 18 Click the Rolls tab. Two new rolls now appear. For each pending roll, view the Roll Valid Signal status.
When one of the following requirements is met, continue with Step 19 .
•
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 a valid signal is not found, refer to the
Cisco ONS 15310-MA
SDH Troubleshooting Guide . 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
If you have completed a roll, you cannot cancel the sibling roll. You must cancel the two
rolls together.
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 19
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 20 .
Note
You cannot complete a roll if you cancelled the sibling roll. You must complete the two rolls
together.
Step 20
For both manual and automatic rolls, click Finish to complete circuit roll process.
