OctetString
The gain allocation per subcarrier. An array of 512 16-bit values, designed for supporting up to 512 (downstream) subcarriers. When more then 512 subcarriers are supported, the status information is reported through multiple (up to 8) segments. The first segment is then used for the first 512 subcarriers. The second segment is used for the subcarriers 512 to 1023 and so on. The aggregate number of utilized octets in the downstream direction depends on NSds; in the upstream direction, it depends on NSus. This value is referred to here as NS. The segment number is in xdsl2SCStatusSegment. Value i (0 <= i < MIN((NS+1)-(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 subcarrier 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 a linear scale. Each value in this array is 16 bits wide and is stored in big endian format.
