Linear ADM Configurations
ONS 15454s can be configured as linear ADMs by configuring one set of OC-N cards as the working path and a second set as the protect path. Unlike rings, linear (point-to-point) ADMs require that the OC-N cards at each node be in 1+1 protection to ensure that a break to the working line is automatically routed to the protect line. Figure 9-35 shows three ONS 15454s in a linear ADM configuration. Working traffic flows from slot 5/node A to slot 5/node B, and from slot 13/node B to slot 13/node C. The protect path is created by placing slot 5 in 1+1 protection with slot 4 at nodes 1 and 2, and slot 13 in 1+1 protection with slot 14 at nodes 2 and 3.
