Figure 17 - Input and Output Timing for CCA Caller Display Service (CDS), e.g., CLIP
Notes:
1) TW/P&E/312 specifies that the AC and DC loads should be removed between 50 to 150ms after the end of the FSK signal,
indicated by CD returning to high. The CNIC2 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.
3) TRIGout represents the ring envelope during ringing.
