O
This pin is a CMOS N-channel open drain output. Flash key will
cause
DP
to go active in either pulse mode or tone mode. In
lock mode, the
DP
keeps low for 300 mS during off-hook delay
time. The timing diagram is shown as Figure 1(a), 1(b), 1(c),
1(d).

O
In pulse mode, this pin remains in low state at all time.
In tone mode, it will output a dual or single tone. Detailed timing
diagram for tone mode is shown in Figure 2(a), 2(b), 2(c), 2(d).
