The line attenuation TFlog(f) is the logarithmic power transfer
function of the line as a function of frequency when both the
near-end and far-end line terminations have the following values:
Source impedance = purely resistive equal to 100 Ohm.
Termination impedance = purely resistive equal to 100 Ohm.
The function TFlog(f) consists of an array of values TFlog(i X Df),
with Df = 4.3125 kHz independent of the sub-carrier spacing used
for the XDSL DMT modulation.
This parameter shall be a set of breakpoints that are represented
by [(t1, TFlog1), (t2, TFlog2), ..., (tN, TFlogN, each breakpoint
occupies 4 octets and consist of a index tn(2 bytes) and a TFlog
value(2 bytes).
The range of valid values for the index i is 0 to 8191.
The range of valid values for TFlog(i X Df) is from 60 down to
-962(units of 0.1 dB), so those two bytes are signed value.
0x0FFFFF is used to indicate that no measurement could be done
for this subcarrier because the attenuation is out of range
that can be represented.
