DSL-524T ADSL Router Manual
This field displays the transmit output power level of the CPE.
Amount of increased noise that can be tolerated while maintaining the designed
BER (bit error rate). The SNR Margin is set by the 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.
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.
This field displays the ADSL data rate.
