Basically most modern GSM phones with modem interface do implement the
ETSI standard with some additional proprietary commands for special
features.
The standard describing this is contained in
ETSI GSM 07.05 : Digital cellular telecommunications system (Phase 2) ;
Use of DTE-DCE interface for Short Message Service (SMS
) and Cell
Broadcast Service (CBS)
and
ETSI GSM 07.07 Digital cellular telecommunications system (phase 2) ; AT
command set for GSM Mobile Equipment (ME)
It is a good idea to actually get the correct Modem Command
documentation for the GSM phone or engine you are using.
Besides all the standard mobile phones with built in modem interface
such as from Siemens or Nokia you also have specific GSM engine modules
which provide all the necessary hardware to operate as modem but do miss
the telephone capability. Those might be interesting for industrial
applications as they tend not to "walk away" easily from a site.
Possible engines might be the Wavecom or Maestro 20 modem which use both
the same internal GSM engine and should be available for around $ 200.
Siemens also sells such a modem with their own engine, mostly (but not
entirely) compatible.
