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).
