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.
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 modem and
the reference signal power level transmitted from
the Central Office DSLAM.
Errored Seconds The error during Showtime, whenever, a given sec
contains CRC error, that second will be declared
error second.
