This manual is divided into uniquely identified and numbered chapters that, in turn, aredivided into sections. Sections are not numbered, but are individually named at the top ofeach page, and are listed in the table of contents.

Data encryption

In order to avoid electronic eavesdropping, data passing between certain elements in the GSM andGPRS network is encrypted. In order to comply with the export and import requirements of particularcountries, this encryption occurs at different levels as individually standardised, or may not be presentat all in some parts of the network in which it is normally implemented. The manual set, of whichthis manual is a part, covers encryption as if fully implemented. Because the rules differ in individualcountries, limitations on the encryption included in the particular software being delivered, are coveredin the Release Notes that accompany the individual software release.
