Advance Information
Notes:
1) From TW/P&E/312. Start time: The CPE should enter the signalling state by applying the DC and AC terminations within this time
2) End time: The CPE should leave the signalling state by removing the DC and AC terminations within this time after the end of Data,
3) PWDN and FSKen are internal signals decoded from CB0/1/2.
4) This signal represents the mode of the DR/STD pin.

indicated by CD returning to high. The MT88E45 should also be taken out of FSK mode at this time to prevent the FSK
demodulator from reacting to other in-band signals such as speech, and DTMF tones.
