3-156 G24-L AT Commands Reference Manual April 15, 2008
Table 3-100 shows the differences between Basic and Advanced audio modes in controlling the
audio.
Audio Setup
The G24-L has two audio modes: 'Basic Audio' and 'Advanced Audio'. Each mode has a different
behavior and a set of relevant AT commands.
Figure 3-2 describes the two audio modes, switching between them and the AT commands related
to each mode.

Path Paths are set automatically
(upon interrupt).
Paths are set manually. All routings are
available; any microphone with any speaker
for each type of sound (voice, keypad, ring,
etc.).
Gain There are two types of
gains: phone (voice,
keypad) and ring.
There is a matrix of gains: a different gain is
saved for each type of sound through a
specific speaker.
For example, one volume level for rings
through the speaker and a different volume
level for rings through the transducer.
Therefore, there will be 16 different volume
levels, which is the product of the number of
output accessories (speaker, headset speaker,
transducer and digital output) and the
number of audio tones (voice, keypad, ring
and alert).
Algorithm Algorithms are set by
ATS94 and ATS96.
