7.7.3 40-DMX-C ROADM Functionality
The 40-DMX-C card works in combination with the 40-WSS-C card to implement ROADM
functionality. As a ROADM node, the ONS 15454 can be configured at the optical channel level using
CTC, Cisco TransportPlanner, and CTM. ROADM functionality using the 40-DMX-C card requires two
single-slot 40-DMX-C cards and two 40-WSS-C double-slot cards (for a total of six slots in the
ONS 15454 chassis).
