7.5 AT^SAIC Audio Interface Configuration
Test command
AT^SAIC =?
Response
^SAIC: (list of supported <io>s), (list of supported <mic>s), (list of supported
<ep>s)
Parameter
See write command
Read command
AT^SAIC?
Response
^SAIC: <io>,<mic>,<ep> OK
Parameter
See write command
Write command
AT^SAIC=<io>[,
<mic>[,<ep>]]
This command configures the interface connections of the active audio mode.
Response
OK
Parameter
<io> Input and output
1 Not supported.
2 Type of audio interface: Analog
<mic> Selects the microphone input (if parameter is not specified, the current
value is used)
1 Selects the microphone 1 connected to analog interface 1.
2 Selects the microphone 2 connected to analog interface 2.
<ep> Selects differential earpiece amplifier (if parameter is not specified, the
current value is used)
1 Selects the earpiece amplifier 1.
2 Selects the earpiece amplifier 2.
3 Selects both amplifiers. Note that both amplifiers are connected in
parallel and therefore, get the same output power if <ep>=3.

Note
· The AT^SAIC Write command is usable only in audio modes 2 – 6. If
AT^SNFS=1, any attempt to use the AT^SAIC Write command returns “+CME
ERROR: operation not allowed”. This is because all default parameters in au-
dio mode 1 are determined for type approval and are not adjustable.
· For use after restart of TC35i, you are advised to store the settings of
AT^SAIC and AT^SNFS to the audio profile set with AT^SNFW. Otherwise,
audio mode 1 (AT^SNFS=1) and audio interface 1 (AT^SAIC=2,1,1) will be
active each time TC35i is powered up.
· The factory defaults of AT^SAIC vary with the selected audio mode.
If AT^SNFS=1 or 4 or 5, then AT^SAIC=2,1,1.
If AT^SNFS=2 or 3 or 6, then AT^SAIC=2,2,2. (Although given by default, this
setting applies to TC35i module only, it cannot be used with the TC35i Termi-
nal where the 2
nd
audio interface is not connected. Nevertheless, you can
configure TC35i Terminal for operation with audio modes 2, 3 or 6 by setting
AT^SAIC=2,1,1 instead. See examples provided with AT^SNFS.)
AT^SNFD can be used to reset the factory defaults.
· To allocate a specific audio mode to each analog audio interface, first select
the audio mode with AT^SNFS and then choose the interface using AT^SAIC.
· See Chapter 7.26 for SNFD, Chapter 7.31 for AT^SNFS and Chapter 7.33 for
AT^SNFW.
