ONE DIALLER
:
PINS
TONE
AND
MUTE
In this system digits are transmitted as two tones
simultaneously, the so called Dual-Tone Multi-Frequency
(DTMF) system. Tone digits are separated by a pause
time. Valid keys are the digits [0] to [9], [
], [#] and
[PAUSE].
The DTMF dialling mode, the tone burst/pause times and
the access pause time depend on the diode options: PTS,
TBT, APT and APT2.
The MUTE pin is an open drain output which requires a
pull-up resistor. MUTE is HIGH when V
DD
is below
power-on reset trip level and when RESET is HIGH.
Figure 14 shows the timing diagram in tone dialling mode
when successively keys [3], [3], [RECALL] and [4] are
dialled.
