The following example displays the tone diagnostics results for ADSL port 8.
The following table lists the tone diagnostic parameters. See the ITU-T’s G.992.3 for more
information.

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).
snrm:
This is the upstream and downstream Signal-to-Noise Ratio Margin (in dB). A
DMT sub-carrier’s SNR is the ratio between the received signal power and the
received noise power. The signal-to-noise ratio margin is the maximum that the
received noise power could increase with the IES-1248 still being able to meet
its transmission targets.
attndr:
This is the upstream and downstream Attainable Net Data Rate (in bit/s).
farEndActatp:
This is the upstream and downstream Far End Actual Aggregate Transmit
Power (in dBm)
i
This is the index number of the DMT sub-carrier.
