7.8.3 40-DMX-CE Card ROADM Functionality
The 40-DMX-CE card works in combination with the 40-WSS-CE 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-CE card requires
two single-slot 40-DMX-CE cards and two 40-WSS-CE double-slot cards (for a total of six slots in the
ONS 15454 chassis).
