LABEL DESCRIPTION
number_of_
subcarries
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.
hlinScale: 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.
