DESCRIPTION

number_of_

Discrete Multi-Tone (DMT) modulation divides up a line’s bandwidth into sub-

subcarries

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.
