SigQual Signal Quality displays the condition of the VF line. Possible values are
Excelent (Excellent), Good, Fair, Poor, or No Signal. These parameters
appear for V.34, V.32terbo, V.32bis, and V.32 modulations.
RcvLevel Receive Signal Level displays, in decibels referenced to one milliwatt (dBm),
the actual strength of the incoming signal. This parameter appears for V.34,
V.32terbo, V.32bis, V.32, and Trellis Multipoint modulations.
Sig/Noise Signal-to-Noise Ratio displays, in decibels, the receive signal strength
relative to noise on the line. This parameter appears for V.34, V.32terbo,
V.32bis, V.32, and Trellis Multipoint modulations.
NrEchLvl Near End Echo Level displays the signal level, in decibels referenced to one
milliwatt (dBm), of that portion of the transmit signal which has been echoed
back by the local line termination. This parameter appears for V.34,
V.32terbo, V.32bis, and V.32 modulations (in 2-wire only).
FarEchLvl Far End Echo Level displays the signal level, in decibels referenced to one
milliwatt (dBm), of that portion of the transmit signal which has been echoed
back by the remote line termination. This parameter appears for V.34,
V.32terbo, V.32bis, and V.32 modulations (in 2-wire only).
FarEchDel Far End Echo Delay displays the roundtrip delay in milliseconds of the far
end echo. This parameter appears for V.34, V.32terbo, V.32bis, and V.32
modulations (in 2-wire only).
