DESCRIPTION
Discrete Multi-Tone (DMT) modulation divides up a line's bandwidth into sub-
carriers (sub-channels) of 4.3125 KHz each.
The first number is the total number of DMT sub-carriers the DSL connection is
using. The second number indicates how many upstream DMT sub-carriers the
DSL connection is using.
The channel characteristics function is represented in linear format by a scale
factor and a complex number. These are the maximum upstream and
downstream scale factors used in producing the channel characteristics
function.
This is the upstream and downstream Line Attenuation (in dB).
This is the upstream and downstream Signal Attenuation (in dB).
