Field Description
DSL Firmware Version The version of firmware in use.
Mode The modulation protocol
Traffic Type The channel type
Status This is the status of the DSL link.
Link Power State Displays the power management state of the DSL
connection.
Line Coding (Trellis) The Trellis Coding status of downstream and
upstream.
SNR Margin(0.1dB) This is a signal-to-noise ratio (SNR) margin for
traffic going in both directions.
Atternuation(0.1dB) An estimate of the average loop attenuation
downstream and upstream.
Output Power(0.1dBm) The total output power in both directions.
Attainable Rate (Kbps): This is the maximum achievable downstream rate.
Rate (Kbps) The actual rate at which data is flowing in both
directions.
