11.19 Bridge and Roll
The CTC Bridge and Roll wizard reroutes live traffic without interrupting service. The bridge process
takes traffic from a designated “roll from” facility and establishes a cross-connect to the designated “roll
to” facility. When the bridged signal at the receiving end point is verified, the roll process creates a new
cross-connect to receive the new signal. When the roll completes, the original cross-connects are
released. You can use the bridge and roll feature for maintenance functions such as card or facility
replacement, or for load balancing. You can perform a bridge and roll on the following ONS platforms:
ONS 15454, ONS 15454 SDH, ONS 15600, ONS 15327, and ONS 15310-CL.
11.19.1 Rolls Window
The Rolls window lists information about a rolled circuit before the roll process is complete. You can
access the Rolls window by clicking the Circuits > Rolls tabs in either network or node view.
Figure 11-17
