Notes:
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
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
3) TRIGout represents the ring envelope during ringing.
