I was wondering if you could use a German version of the 7390 in the UK with FTTC. I know you can't for ADSL but was wondering if standards in both countries were in line.
For the avoidance of doubt, 'German' versions of Fritz!boxes will not work in the UK 'out of the box'. They can be 'hacked' but this invalidates the 5 year warranty supported by the manufacturer. I had reason to return a 7390 last year and AVM's support was first-class. I am just about to replace my 3 year old (in truth a 1 year old box as rather than fix my old box, AVM replaced it) 7390 with a 7490 international (open to offers for my current box ).
I am not sure what all this talk about IP addresses is all about. All that is needed to get a 7390 up and running on any BTW FTTC line is VLAN- 101, VP1 - 1, VC1 - 32, PPPoE ticked, Annex A - ticked and your ISP Username and password.
I have had FTTC for nearly two years and apart from one glitch my connection has been pretty well rock solid at 93/27 on an 80/20 IP profile. Before you ask, my profile limits both the up and down speeds. I live about 300M from my cabinet.
International versions of Fritz!boxes and accessories can be purchased from German distributors. International versions will give you a GUI in English! The UK International version will also give you a UK PSU and 'Y' lead. I am currently running a Fritz!Repeater (german version) on my network. It has a Euro plug and everything is in German. It works as it is only connecting to my 7390. I also have 3 Fritz!Fon MT-F phones.
The 'Pro' of the Fritz!Box 7390/7490 is a one stop solution for FTTC and home phones. The 'con' is if the F!B fails then the one stop solution has a 10 day gap whilst the old box is sent to Germany and the new one arrives.
