FRITZ! Box 7590 (A/CH version)
Question about FRITZ! Box 7590 (A/CH version)
Are there any technical differences between the A/CH and D versions, or would one of them not work in the other country?
If you only need the Fritzbox as a router, you are better off with the D version, as software updates come faster. The DSL modem part does not work in Switzerland with the D version.
Just as mentioned, for direct use on the DSL connection, CH version is necessary.
There may be differences in the firmware. Maybe the German version is pre-configured for Germany and the Swiss version for Switzerland. But the hardware part is identical. It is important that you buy the right VDSL modem/router. There is always talk of VDSL and VDSL 2. In our latitudes, however, this means the same thing. What is important is the transmission type. If it is an analogue line, then you need a modem type Annex A. If it is an ISDN line, then you need the type Annex B.
During my research before buying my FritzBox, I found out that there is Annex A and -B. So the D version is different from the international version (A/CH/Intl). As I said, I read this somewhere and did not have to experience it myself.
