Wait at least one minute after using the line diagnostic set command before
using this command.
The following example displays the line diagnostics results for DSL port 1.
The following table lists the line diagnostics test parameters that display, see the ITU-T’s

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.
