AVM Fritz!Box Fon, posted: 3-OCT-2007 03:03
In order to take advantage of the full capabilties of the Fritz!Box Fon it requires to be connected to the ADSL socket of your ADSL filter as well as to the filter's phone socket. By doing so regular phones, connected directly to the Fritz!Box Fon, become "hybrid" - that means you are able of placing and receiving phone calls through VoIP and also through the regular landline. So you can e.g. place cheap outgoing calls through VoIP while still being reachable on your landline number with the same phone.
For your initial installation you need at least two standard RJ11-phone cables, of which one would connect the "DSL"-socket of the Fritz!Box Fon with the ADSL filter and the other a regular phone with one of the "FON"-sockets of the Fritz!Box Fon. If you want to run a second phone, you'll need a third standard RJ11-phone cable.
In order to hook up your Fritz!Box Fon to the telephone landline, you'll need a custom cable as depicted below connecting the ADSL filter's BT-socket with the "ISDN/analog"-socket of the Fritz!Box, which presumably isn't sold anywhere in NZ. This special cable needs to connect pin 2 and 5 of a BT431A plug (which is connected to the ADSL filter) with pins 1 and 8 of an RJ45 plug (which is connected to the Fritz!Box).
With a crimping tool and an RJ45-plug you can modify a regular BT-phone cable easily within seconds. Alternatively you could try connecting a cut BT-phone cable with a cut RJ45 network cable through a screw terminal.
If you wonder why AVM have placed the analogue telephone signal on the outer two pins of the "ISDN/analog"-socket instead of the inner ones, as it's usually the case with western plugs, here's the answer: Pins 3 to 6 are used for ISDN, a digital phone system, which the Fritz!Box Fon also fully supports alternatively analoge landlines.
