Phase jitter 20 ± 300 Hz, Frequency offset | Paradyne 6800 instruction

Modem/DSU Commands

Phase jitter 20 ± 300 Hz

Displays the value of the high frequency range phase jitter that, when exceeded, causes the device to report a threshold alert.

Frequency offset

Displays the frequency offset level value that, when exceeded, causes the device to report a threshold alert.

Non-linear distortion

Displays the non-linear distortion value that, when exceeded, causes the device to report a threshold alert.

Refer to the Change Thresholds (cht) command for a detailed description of the threshold information.

The following fields and their possible values display for the 3910, 3911, 3920Plus and 3921Plus modems:

•Retrains: 1±255, computed for the last 15 minutes.

•Gain hits: 1±255, computed for the last 15 minutes.

•Phase hits: 1±255, computed for the last 15 minutes.

•Impulse hits: 1±255, computed for the last 15 minutes.

•Dropouts: 1±255, computed for the last 15 minutes.

•Receive level (high): Receive level in ± dBms. Possible range: 15 to 0.

•Receive level (low): Receive level in ± dBms. Possible range: 50 to 16.

•Signal/noise: Signal/noise ratio in dB. Possible range: 5 to 40.

•Phase jitter 20±300 Hz: In degrees (deg). Possible range: 1 to 45.

•Freq offset: Frequency offset in Hertz (Hz). Possible range: 1 to 15.

•Non-linear distortion: Non-linear distortion in ± dB. Possible range: 50 to 15.

•Signal quality threshold: An alarm is generated if the measured signal quality is less than

the signal quality threshold. Possible values: excellent, good, fair, poor and no signal.

•Near echo: Near echo threshold in ± dBm. Possible range: 38 to 0.

•Far echo: Far echo threshold in ± dBm. Possible range: 38 to 0.
