Paradyne 6800 manual Non-linear distortion, Freq offset 1±10 Hz

COMSPHERE 6800 Series Network Management System

This results form contains the following fields:

Receive level

Displays the measure received signal level (in dBm).

Signal/noise

Displays the measured signal-to-noise ratio (in dB).

Non-linear distortion

Displays the measured non-linear distortion (in dB).

Retrains

Displays the number of retrain counts during the last 15 minutes.

Signal quality

Displays the measured signal quality. Possible values are excellent, good, fair, poor, no signal.

Near end echo

Displays the echo (in dBm) measured at the near end device.

Far end echo

Displays the echo (in dBm) measured at the far end device.

Far end delay

Displays the delay (in milliseconds). Maximum delay is 1 1/2 seconds.

Echo freq offset

Displays the measured echo frequency offset (in Hz).
