Note:
1. TW/P&E/312 specifies that the AC and DC loads should be removed between 50 to 150 mS after the end of the FSK signal,
indicated by The
CD
returning to high. The SC88E43 may also be powered down at this time.
2. FSKen should be set low when FSK is not expected to prevent the FSK demodulator from reacting to other in-band signals such as
speech,and DTMF tones.
TRIGou
represents the ring envelop during ringing.
