Data Functionality
6.5.4.1  TDMA
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.
  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.
  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..
