How to use this document

The target audiences for this document are all categories of software and hardware
developers, system integrators and expert end-users of SIEMENS GSM wireless modules.
The content applies in particular to current users and developers whose applications are
utilizing SIEMENS TC35/TC37/TC35T for their communications purposes.
The aim of this document is to provide information and offer support in order to facilitate the
transition towards the new generation of SIEMENS wireless modules, namely, TC35i.
Information provided here is based on official technical manuals and released specifications
for TC35 and TC35i. The naming conventions used in this document follow those of source
documentation.
The authors presume the readers are already familiar with the contents of those manuals.
The document presents migration issues in detail using comparison tables between the
modules and covers topics ranging from hardware specifications to AT-command interface.
Technical specifications and interfaces to GSM telecom services are described and
compared in detail as well as all the relevant features. AT-command interface was given
particular attention since it represents the main tool available to developers through which
applications can be controlled. Available commands for both TC35i and TC35T are listed and
classified according to their implementation within each of the modules. Differences in test,
query and execution syntax as well as in available parameters are noted for each command.
Commands are classified in three main groups: jointly supported commands, commands
new with respect to TC35 and TC35 commands not supported by TC35i.
