9.1 Card Overview
The card overview section contains card overview, software compatibility, interface class, and channel allocation information for optical add/drop cards.

Note Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. The cards are then installed into slots displaying the same symbols. For a list of slots and symbols, see the “Card Slot Requirements” section in the Cisco ONS 15454 Hardware Installation Guide.
Optical add/drop cards are divided into two groups: band optical add/drop multiplexer (OADM) cards and channel OADM cards. Band OADM cards add and drop one or four bands of adjacent channels. The cards in this chapter, including the 4-Band OADM (AD-4B-xx.x) and the 1-Band OADM (AD-1B-xx.x) are utilized only in the C band. Channel OADM cards add and drop one, two, or four adjacent channels; they include the 4-Channel OADM (AD-4C-xx.x), the 2-Channel OADM (AD-2C-xx.x), and the 1-Channel OADM (AD-1C-xx.x).

Note For information about L band add and drop capability, see Chapter10, “Provision Reconfigurable Optical Add/Drop Cards”

9.1.4 DWDM Card Channel Allocation Plan
ONS 15454 DWDM channel OADM and band OADM cards are designed for use with specific channels in the C band. In most cases, the channels for these cards are either numbered (for example, 1 to 32) or delimited (odd or even). Client interfaces must comply with these channel assignments to be compatible with the ONS 15454 system.
Table 9-7 lists the channel IDs and wavelengths assigned to the C-band DWDM channels.

Note In some cases, a card uses only some or all of the channels listed in a band. Also, some cards use channels on the 100-GHz ITU-T grid while others use channels on the 50-GHz ITU-T grid. See specific card descriptions in Appendix B, “Hardware Specifications,” for more details.
