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.
This number indicates how many upstream and downstream DMT sub-
carriers the ADSL connection is using.
hlinScale: The channel characteristics function is represented in linear format by
a scale factor and a complex number. This is the maximum upstream
and downstream scale factor used in producing the channel
characteristics function.
latn: This is the upstream and downstream Line Attenuation (in dB).
satn: This is the upstream and downstream Signal Attenuation (in dB).
