7.1.4 Channel Allocation Plans
ONS 15454 DWDM ROADM cards are designed for use with specific channels in the C band and
L band. In most cases, the channels for these cards are either numbered (for example, 1 to 32 or 1 to 40)
or delimited (odd or even). Client interfaces must comply with these channel assignments to be
compatible with the ONS 15454 system.
. The following cards operate in the C band:
