  | Max Tx Power  | This field displays the transmit output power level of the CPE.  |

  | SNR Margin | 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.  |

  | 
  | Line  | Attenuation is the decrease in magnitude of the ADSL line signal between the  | 
  | 
  | Attenuation | 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.  |
