6.1.4 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 6-6
In some cases, a card uses only some or all of the channels listed in a band. Also, some cards use channels
Note
on the 100-GHz ITU-T grid while others use channels on the 50-GHz ITU-T grid. See specific card
