7.3.3 32WSS ROADM Functionality

The 32WSS card works in combination with the 32DMX 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 Cisco Transport Manager (CTM). ROADM functionality using the

32WSS card requires two 32DMX single-slot cards and two 32WSS double-slot cards (totalling six slots

needed in the ONS 15454 chassis).

For other cards’ ROADM functionality, 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.

Note A terminal site can be configured using only a 32WSS card and a 32DMX card plugged into the east or

west side of the shelf.

7.3.4 32WSS Power Monitoring

Physical photodiodes P1 through P69 monitor the power for the 32WSS card. Table 7-8 shows how the

returned power level values are calibrated to each port.

7.3.5 32WSS Channel Allocation Plan

The 32WSS Card’s channel labels, frequencies, and wavelengths are listed in Table 7-9.
