embedded in the silent interval between the first and second ringing.
The NW6006 can detect and demodulate the incoming Bell-202 FSK
data. In CIDCW service, information about an incoming caller is sent
to the subscriber who is engaged in another call. A CPE Alerting
Signal (CAS) indicates that a CIDCW data is incoming. The NW6006
can detect the alerting signal and demodulate the incoming FSK
information which contains CIDCW data. The demodulated data is
output onto the serial interface.

FSK Data Interface Mode 0: FSK bit stream is output directly.
FSK Data Interface Mode 1: FSK byte is stored in a 1-byte buffer, which can be
read serially by the microcontroller.
FSK Demodulation is enabled. Tip/Ring input (GS1) is selected. In FSK
Demodulation (CB0 = ‘1’), DR / STD is DR .
Hybrid DT-AS Detection is enabled. Hybrid Receive input (GS2) is selected.
DR / STD is STD .
When CB0 is high (‘1’): Stutter Dial Tone Detection is enabled. CD / STRDT is

When CB0 is low (‘0’): Stutter Dial Tone Detection is disabled. CD / STRDT is CD .
Tip/Ring DT-AS Detection is enabled. Tip/Ring input (GS1) is selected. DR / STD
is STD .
When CB0 is high (‘1’): Stutter Dial Tone Detection is enabled. CD / STRDT is
STRDT .
When CB0 is low (‘0’): Stutter Dial Tone Detection is disabled. CD / STRDT is CD .
Tip/Ring DT-AS detection is required for Bellcore MEI and BT on-hook CLIP.
When CB0 is high (‘1’): the NW6006 will be powered down. It draws minimal
power supply current.
When CB0 is low (‘0’): for factory testing only.

Caller ID FSK information transmitted in ITU-T V.23 format. When the
subscriber is engaged in a call, the arrival of information about
another incoming call is indicated by a Loop State Tone Alert Signal.
