Note
Using the bridge and roll feature, you can upgrade an unprotected circuit to a fully protected circuit or
downgrade a fully protected circuit to an unprotected circuit.
Performing bridge and roll on an STM64C might cause a traffic hit of 50 ms.

This procedure reroutes live traffic without interrupting service. You can
use the Bridge and Roll wizard for maintenance functions such as card
replacement or load balancing. A circuit consists of a source facility, one
or more destination facilities, and intermediate facilities (path).

for circuit creation procedures.
To route circuits on protected ports, you must create a protection group
using the
"DLP-D73 Create a 1+1 Protection Group" task on
page 17-64
or the
"NTP-D41 Create the MS-SPRing" procedure on
page
5-13.
When a roll involves two circuits, a data communications channel
(DCC) connection must exist. See the
Regenerator-Section DCC Terminations" task on page
Use the
"NTP-D199 Locate and View Circuits" procedure on page 7-2
to verify that the planned Roll To paths are in service. Verify that the
planned Roll To and Roll From paths are not in the Roll Pending status,
used in test access, or used in a loopback. Refer to the
Cisco ONS 15454 SDH Troubleshooting Guide to clear any alarms.
