NAME
DESCRIPTION
No answer tone detected.
Indicates detection of 2225 Hz answer tone in Bell mode
or 2100 Hz in CCITT mode. The device must be in
originate mode for detection of answer tone. For CCITT
answer tone detection, bit D0 of the Tone Register must
be set to a 1.
No carrier detected in the receive channel.
Indicates carrier has been detected in the receive
channel.
No unscrambled mark.
Indicates detection of unscrambled marks in the received
data. A valid indication requires that unscrambled marks
be received for > 165.5 ± 6.5 ms.
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.
Not used. Mask in software.
