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-1248-51V 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.
log(dB)
This is a format for providing channel characteristics. It provides
magnitude values in a logarithmic scale. This can be used in analyzing
the physical condition of the ADSL line.
QLN(dBm)
The Quiet Line Noise for a DMT sub-carrier is the rms (root mean
square) level of the noise present on the line, when no ADSL signals
are present. It is measured in dBm/Hz. The QLN can be used in
analyzing crosstalk.
SNR(dB)
This is the upstream and downstream Signal-to-Noise Ratio (in dB). A
DMT sub-carrier’s SNR is the ratio between the received signal power
and the received noise power. The SNR can be used in analyzing time
dependent changes in crosstalk levels and line attenuation (such as
those caused by temperature variations and moisture).
