•
Asynchronous Circuit Switch Data (CSD) according to EIA/TIA 136-350. AMPS
•
AMPS Data over the voice channel. In this case an external modem connected to the analog audio
signals (ATMS, AFMS) is needed.
•
Microburst/Vburst mode (by Aeris).
•
The DM-15/DM-25 module supports Aeris Microburst and Vburst protocols. These protocols enable
applications to send either short messages or 1045 byte data-grams to the Aeris data center. The short
messages in Microburst mode are sent using dialed digits inside a feature request. Feature requests are
pages with a ‘*’ character followed by 15 digits. In Microburst/Vburst mode the DM-15/DM-25
module does not use either IRDB or WIN4 list.

module does not use either IRDB or WIN4 list.
•
The Microburst and Vburst service is detected by listening for pages to area code 175 or area code 180
respectively.
•
Application providers that use Aeris Microburst/Vburst protocols must obtain Microburst and Vburst
documentation from Aeris (see section 1.4)
•
Sony Ericsson Burst Modem.
•
The Sony Ericsson Burst Modem protocol enables applications to send 250-byte messages on an
AMPS voice channel.
•
In order to have a complete solution customers must develop an application to control the module,
obtain service with a cellular provider, and develop a call center to process incoming data packets or
voice calls.
voice calls.
•
The DM-15/DM-25 module supports several control channel selection modes. The Sony Ericsson
Burst Modem protocol may use a standard IRDB lookup mode or a GTE Win4 scanning mode..
