7.10.3 40-WSS-C ROADM Functionality
The 40-WSS-C card works in combination with the 40-DMX-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-WSS-C card requires two
40-WSS-C double-slot cards and two 40-DMX-C single-slot cards (for a total of six slots in the
ONS 15454 chassis).
For information about ROADM functionality for other cards, see that card’s description in this chapter.
For a diagram of a typical ROADM configuration, see the “9.1.4 ROADM Node” section on page 9-12.
7.10.4 40-WSS-C Power Monitoring
The 40-WSS-C has physical diodes that monitor power at various locations on the card. Table 7-29 lists
the physical diode descriptions.
