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 Router and the reference signal
power level transmitted from the Central Office DSLAM.
Data Rate
This field displays the ADSL data rate.

System Log
The ADSL Router keeps a running log of events and activities occurring on the Router. If the
device is rebooted, the logs are automatically cleared.
3.6.3
Statistics
The ADSL Router keeps statistic of traffic that passes through it. You are able to view the
amount of packets that pass through the Router on both the WAN port and the LAN port.
The traffic counter will reset if the device is rebooted. You can select Ethernet/ADSL to view
the statistics report of LAN/WAN.
