Versions

Most FRITZ!Box devices come in three versions:
  • German version for Germany
  • German version for Austria

  • International (English) version


Beside the obvious different language on the web interface, they also differ in the fact that the international version is available in two ADSL standards: ITU G.992.1 Annex A and ITU G.992.1 Annex B. The German version is only available as Annex B. This is due to fact that Annex A is not used in Germany (in Germany, both analogue and ISDN line are using Annex-B ADSL while in most of the world Annex-A ADSL is used on analogue lines and Annex B ADSL is used on ISDN lines).

The difference is in the use of the available frequency spectrum of analogue telephone lines (POTS).

Spectral allocation of services in a typical telephone line (from low to high frequencies)
|--ANALOG--|---------ISDN---------|------------------------------DSL----------------------------|

The Annex-A mode is more efficient since it uses the whole available (ISDN+DSL) spectrum. It allows for longer distances from the central DSL Access Multiplexer (DSLAM) to the subscriber. In Annex-B mode the ISDN range is spared (wasted), even for ADSL-Over-Analog subscribers.

In principle, the Fritz!Box can be changed[2] from German/Annex-B to European/British/Annex-A and vice versa by firmware. However, the German version is shipped with German-specific cables and adaptors for ISDN lines. These are difficult to convert to the more usual ADSL connection found elsewhere in Europe. The 7390 model, for example, includes a proprietary split Y cable which is wired specifically for German ISDN lines, and is terminated in RJ45 plugs which do not fit the standard RJ11 ADSL sockets found elsewhere in Europe. The ADSL/DSL socket on the box is also RJ45, and although an RJ11 cord can in principle be plugged into an RJ45 socket, doing so may damage (bend) the other line pins and will in any case prevent the use of the box for fixed-line telephony. The International version comes with specially wired adapters for this purpose which are not sold separately. There are, furthermore, rumoured hardware differences between the German and International editions which have not been definitively confirmed or denied but which, if true, would prevent even firmware-adapted versions of the German box from synching over all but the most perfect ADSL connections.

For the newer models the available international firmware updates may be somewhat behind the newest German ones.
