Description: The gain allocation per sub-carrier. An array of 512 16-bits values, designed for supporting up to 512 (downstream) sub- carriers. When more then 512 sub-carriers are supported, the status information is reported through multiple (up to 8) segments. The first segment is then used for the first 512 sub-carriers. The second segment is used for the sub-carriers 512 to 1023 and so on. The aggregate number of utilized octets on downstream direction depends on NSds, and on upstream direction it depends on NSus. This value is referred here as NS. The segment number is in vdsl2SCStatusSegment. Value i (0 <= i < MIN(NS-(segment-1)*512,512)) in each segment is set to a value in the range 0 to 4093 to indicate that the respective downstream or upstream sub-carrier j (j=(segement-1)*512+i) has the same amount of gain value. The gain value is represented as a multiple of 1/512 on linear scale. Each value in this array is 16 bits wide and is stored in big endian format. This table is from draft-ietf-adslmib-vdsl2-01.txt.
