1.3 Document Conventions
Throughout the document, the GSM engines are referred to as:
ME (Mobile Equipment)
MS (Mobile Station)
TA (Terminal Adapter)
DCE (Data Communication Equipment)
Facsimile DCE (FAX modem, FAX board)
To control your GSM engine you can simply send AT Commands via its serial interface. The controlling device at the
other end of the serial line is referred to as:
TE (Terminal Equipment)
DTE (Data Terminal Equipment) or ‘the application’ (probably running on an embedded system).
All abbreviations and acronyms used throughout this document are based on the GSM specifications. For definitions
