Object
Subcarrier mask. A bitmap of 4096 bits that allows masking up to 4096 upstream subcarriers. If bit i (0 <= i < NSCus) is set to '1', the respective upstream subcarrier is masked, and if set to '0', the respective subcarrier is unmasked. Note that there should always be unmasked subcarriers (i.e., this object cannot be all 1's). Also note that if NSCus < 4096, all bits i (NSCus < i <= 4096) should be set to '1'.
