Notes:
1. SIN227 specifies that the AC and DC loads should be applied at 20
±
5 mS after the end of the dual tone alert signal.
2. SIN227 specifies that the AC and DC loads should be removed between 50
150 mS after the end of the FSK signal.
The W91031 may also be placed in a sleep condition.
3. The FSKE pin should be set low to disable the FSK demodulator when FSK is not expected. The tone alerting signal speech
and the DTMF tones are in the same frequency band as the FSK signal.
4. The W91031 may not be woken up at this ring signal after the FSK data has been processed.
