Again, note that using a single-ended connection includes losing power (-6dB) as
compared to a differential connection.
In the case of a 32  speaker, a cheaper and smaller solution can be
implemented where R1 = 82  and C2 = 6.8µF (ceramic).
Also note that the connection between the speaker and the AirPrime SL808X
Embedded Module pins must be designed to keep the serial impedance lower
than 1.5  when it is connected in single-ended mode.
4.10.3.5 Recommended characteristics
• Type: 10 mW, electro-magnetic
Impedance: 8  for hands-free
•
• Sensitivity: 110dB SPL minimum (0dB = 20 µPa)
• Frequency response must be compatible with GSM specifications

4.10.4 Supported voice features

The AirPrime SL808X Embedded Module modem supports the voice-related
features listed in Table 4-28, and
services.
Table 4-29 details its support for supplementary
Comments
This is a GSM-specific capability that supports transmitting
information over GSM network signalling channels.
Both A5/1 and A5/2 voice encryption are supported.
3GPP TS 11.14
SIM Application Toolkit commands are stored on the SIM. These
commands enable the SIM card to proactively drive the GSM
host device and support interactions between the network and
the end user.
Several audio features, such as 'Incoming Call' and 'New SMS
message', can be configured in Watcher.
Up to 5 remote parties are supported on a single call, plus an
additional party on hold (on a separate call).
