Upgrade Protection: Terminal to Linear
Use the Upgrade Protection: Terminal to Linear wizard to convert a 1+1 point-to-point (terminal) configuration (two nodes) to a 1+1 linear add/drop multiplexer (ADM) (3 nodes) without losing traffic. The Upgrade Protection: Terminal to Linear wizard includes the following pages:

Select Node to Add to Protection

After you complete these pages, the wizard continues with instructions for physically refibering the nodes. Follow each step as instructed by the wizard as it guides you through the process of refibering the working path between nodes and forcing the traffic back to the working path.
