DESCRIPTION
Indicates normal received signal.
Indicates low received signal quality (above average
error rate). Interacts with Special Register bits D2, D1.
No call progress tone detected.
Indicates presence of call progress tones. The call
progress detection circuitry is activated by energy in the
normal 350 to 620 Hz call progress bandwidth.
Condition not detected.

900 Hz SCT tone detected in V.23 mode.
2100 Hz or 2225 Hz answer tone detected in QAM,
DPSK mode
No carrier detected in the receive channel.
Indicated carrier has been detected in the received
channel.
No unscrambled mark.
Indicates detection of unscrambled marks in the received
data. Should be time qualified by software.
Continuously outputs the received data stream. This data
is the same as that output on the RXD pin, but it is not
disabled when RXD is tri-stated.
No S1 pattern being received.
S1 pattern detected. Should be time qualified by
software. S1 pattern is defined as a double di-bit
(001100..) unscrambled 1200 bps DPSK signal. Pattern
must be aligned with baud clock to be detected.
Received signal level below threshold, (typical @ -25 dBm0);
can use receive gain boost (+18 dB).
Received signal above threshold.
