DESCRIPTION
D2
Answer Tone
0
No answer tone detected.
Received
1
In call init mode, indicates detection of 2225 Hz answer
tone in Bell mode (TR bit D0 = 0) or 2100 Hz if in CCITT
mode (TR bit D0 = 1). The device must be in originate
mode for detection of answer tone. Both answer tones
are detected in demodulation mode.
D3
Carrier Detect
0
No carrier detected in the receive channel.
1
Indicated carrier has been detected in the received
channel.
D4
Unscrambled
0
No unscrambled mark.
Mark Detect
1
Indicates detection of unscrambled marks in the received
data. Should be time qualified by software.
D5
Receive Data
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.
D6
S1 Pattern
0
No S1 pattern being received.
Detect
1
S1 pattern detected. Should be time qualified by
software. S1 pattern is defined as a double di-bit
(001100..) unscrambled 1200 bit/s 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).
D7
Receive Level
Indicator
0
1
Received signal above threshold.
