ENHANCED CALLING LINE IDENTIFIER WITH CALL WAITING

PRELIMINARY
FUNCTIONAL DESCRIPTION
Ring or Line Reversal Detector
It can be detected the Ringing signal or the Line polarity reversal signal as in the CLIP, CID, and CDS protocols.
The signals between Tip and Ring block pass through the bridge circuitry and the rectified signal is input to the
RD (pin #6). If the rectified signal is larger than the internal threshold V
TH
, the RTB block stays in the low level
while the signal is maintained by the external resistor and capacitor . For the Line polarity reversal detection,
the logic low level section within RTB block is also decided by the external resistor and capacitor value.
When a Ringing or a Line polarity reversal signal is detected, an active low pulse is outputted by the interrupt
generator to the INTB (pin#14) .
