MDD Upstream Ambiguity List Reduction
The C4/c CMTS places all of the upstream channels in the cable mac on the ambiguity list, which enables modems to
perform initial ranging on any upstream channel in the cable mac. However, when there are more than 16 upstream
channels in the cable mac, the ambiguity list also contains more than 16 channels, which is not supported by some D3.0
modems. In this case, those modems will not be able to register or may register as non-bonded.
When the upstream ambiguity list reduction feature is enabled, because the list will be limited to contain no more than 16
upstream channels, multiple fiber nodes that are configured within the cable mac will contain an equal number of
