If the modem is receiving a signal, the signal quality appears on the LCD's bottom line. Press the key to scroll and view the receive signal level, signal-to-noise ratio, near end echo level, far end echo level, far end echo delay, and echo frequency offset. If the modem is not receiving a signal, the message No Signal appears on the LCD.

SigQual	Signal Quality displays the condition of the VF line. Possible values are
	Excelent (Excellent), Good, Fair, Poor, or No Signal. These values appear
	for 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 value appears for
	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 value appears for 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 value appears for
	V.32 terbo, V.32bis, and V.32 modulations.
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 value appears for
	V.32 terbo, V.32bis, and V.32 modulations.
FarEchDel	Far End Echo Delay displays the roundtrip delay in milliseconds of the far
	end echo. This value appears for V.32 terbo, V.32bis, and
	V.32 modulations.
EchoFreqOff	Echo Frequency Offset displays the frequency offset of the far end echo.
	This value appears for V.32 terbo, V.32bis, and V.32 modulations.
