Status of SNR Margin, Line Attenuation and Data Rate
SNR Margin:
Amount of increased noise that can be tolerated while maintaining the designed
BER (bit error rate). The SNR Margin is set by Central Office DSLAM. If the SNR Margin is
increased, bit error rate performance will improve, but the data rate will decrease. Conversely,
if the SNR Margin is decreased, bit error rate performance will decrease, but the data rate will
increase.
72
Line Attenuation:
Attenuation is the decrease in magnitude of the ADSL line signal between
the transmitter (Central Office DSLAM) and the receiver (Client ADSL Modem), measured in
dB. It is measured by calculating the difference in dB between the signal power level received
at the Client ADSL Routerand the reference signal power level transmitted from the Central
Office DSLAM.
Data Rate:
This field displays the ADSL data rate.
