COMSPHERE 392xPlus Modems
EchoFreqOff | Echo Frequency Offset displays the frequency offset of the far end echo. This |
| parameter appears for V.34, V.32 terbo, V.32bis, and V.32 modulations (in |
| |
Phase Hts | Phase Hits reports the total hit count of sudden uncontrolled changes in the |
| phase of the receive signal for the past 15 minutes. This parameter appears for |
| V.32 terbo, V.32bis, and V.32 modulations (in |
Impul Hts | Impulse Hits reports the total hit count of large burst or spikes that are larger |
| than normal peaks of random white noise for the past 15 minutes. This |
| parameter appears for V.32 terbo, V.32bis, and V.32 modulations (in |
| only). |
DropOuts | Drop Outs reports the total number of large reductions in channel gain for the |
| past 15 minutes. This parameter appears for V.32 terbo, V.32bis, and V.32 |
| modulations (in |
Retrains | Retrains displays the number of retrains over the last 15 minutes of operation. |
| The total |
| appears for V.32 terbo, V.32bis, V.32, and Trellis Multipoint modulations (in |
| |
Phas Jtr | Phase Jitter is the |
| carrier. The jitter is typically introduced by analog power supplies and is |
| predominantly sign waves with a frequency of 50 Hz or 60 Hz. This parameter |
| appears for V.32 terbo, V.32bis, and V.32 modulations (in |
NonLinear | |
| |
| parameter appears for V.32 terbo, V.32bis, V.32, and Trellis Multipoint |
| modulations (in |
FreqOffset | Frequency Offset reports the variation in all frequencies in the voice band. This |
| parameter appears for V.32 terbo, V.32bis, and V.32 modulations (in |
| only). |
Gain Hts | Gain Hit reports the total number of rapid changes in the receiver power level |
| for the past 15 minutes. This parameter appears for V.32 terbo, V.32bis, and |
| V.32 modulations (in |
