FUNCTION
LOCK
The function of this terminal is to prevent "0" dialing and
"9" dialing under PABX system long distance call
control. When the first key input after reset is 0 or 9, all
key inputs, including the 0 or 9 key, become invalid and
the chip generates no output. The telephone is
reinitialized by a reset.
The function of the LOCK pin is shown below:

N-channel open drain dialing pulse output.
Flash key will cause DP to be active in either tone mode
or pulse mode.
In lock mode, the DP remains low for 300 mS during off-
hook delay time.
The timing diagram for pulse mode is shown in Figure
1(a, b, c, d).
During pulse dialing, this pin remains in low state
regardless of keypad input. In tone mode, it will output a
dual or single tone.
A detailed timing diagram for tone mode is shown in
Figure 2(a, b, c, d).
