Description: The gain allocation per sub-carrier. An array of 8192 bytes, designed for supporting up to 4096 sub-carriers. The number of utilized octets on downstream direction depends on NSCds, and on upstream direction it depends on NSCus. This value is referred here as NSC. Value i (0 <= i < NSC) is in the range 0 to 4093 to indicate that the respective downstream or upstream sub-carrier 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.
