the VCE port k into the loop for which Xlin(f) is being
reported. Each array entry represents the
Xlinds(f = n*deltaf) value for a  particular subcarrier
index n. The Xlin(f = n*deltaf) value is represented as
((XLINSC/2^15) * ((a(n) + j*b(n))/2^15)), where a(n) and
b(n) are signed integers in the (-2^15 + 1) to (+2^15 - 1)
range. The format of XLINps is defined in ITU-T G.993.5.

For each 16-bit tuple, the first 16-bit value, a(n), can
have values in the range -32,767 to 32,767. The second
16-bit value, b(n), can have values in the range -32,767
to 32,767. In each tuple the value for a(n) is loaded
first.

A special value (-32,768) indicates that no measurement
could be done from line k into this line for subcarrier n;

Another special value indicates that there is no phase
information and the magnitude of Xlin(f = n*deltaf) is
((XLINSC/2^15)*(a(n)/2^15)), and for G.993.5 this special
value is indicated as a(n) >= 0 and b(n) = 0
