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) or 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
plainly 'the application' (probably running on an embedded system).
All abbreviations and acronyms used throughout this document are based on the GSM specifications. For defi-
nitions please refer to TR 100 350 V7.0.0 (1999-08), (GSM 01.04, version 7.0.0 release 1998).

Quick reference table

Each AT command description includes a table similar to the example shown below. The table is intended as a
quick reference to indicate the following functions:

Usage is dependent on conditions specified for the command, or not all command types are PIN
§
protected (for example write command PIN protected, read command not).
Note: The table provided in Section 20.3,
uses the same symbols.

AT command is usable, but under the restrictions specified in the section related to the command.
§
Note: The columns MUX1, MUX2 and MUX3 are relevant only when the GSM engine operates in Mul-

by using the Multiplexer protocol. Usage is the same on ASC0 and MUX1.
