7.6.3 32DMX-L ROADM Functionality
The 32DMX-L card works in combination with the 32WSS-L card to implement ROADM functionality.
AS a ROADM node, the ONS 15454 can be configured to add or drop individual optical channels using
CTC, Cisco TransportPlanner, and CTM. ROADM functionality using the 32DMX-L card requires two
32DMX-L single-slot cards and two 32WSS-L double-slot cards (for a total of six slots in the
ONS 15454 chassis).
