NOTE

Not all conditions are available at 4800 bps.

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.32 terbo, 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.32 terbo, 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.32 terbo, 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.32 terbo,
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.32 terbo, 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.32 terbo, V.32bis, and V.32
modulations (in 2-wire only).
