Fritzbox 7490 ISDN landline and intenral ISDN S0 bus links

Posted by jpluimers on 2022/08/08

Somehow WordPress.com failed to post it on the scheduled date 20150331, not sure why.

Though ISDN has been phased out in The Netherlands as and almost phased out in Germany, you can still use end user Terminal Equipment on the internal S-bus.

Since scheduling the post for 2015, the same information as the original diagram below appeared in text form on Wikipedia and there it also adds TAE connector information: Fritz!Box: Belegung der kombinierten DSL-Telefon-Buchse – Wikipedia

Die Anschlussbelegung der Kombibuchse ist wie folgt:[44]

  • Pin 1: ISDN 1a
  • Pin 2: ISDN 1b
  • Pin 3: analog La
  • Pin 4: DSL
  • Pin 5: DSL
  • Pin 6: analog Lb
  • Pin 7: ISDN 2a
  • Pin 8: ISDN 2b

Der RJ-45-Stecker am grauen DSL-Zweig des Y-Kombikabels zeigt folgende Belegung:[44]

  • Pin 4: DSL
  • Pin 5: DSL

Die übrigen Pins sind unbenutzt.

Am schwarzen Telefonzweig ist der RJ-45-Stecker folgendermaßen belegt:

  • Pin 1: analog La
  • Pin 2: frei
  • Pin 3: ISDN 2a
  • Pin 4: ISDN 1a
  • Pin 5: ISDN 1b
  • Pin 6: ISDN 2b
  • Pin 7: frei
  • Pin 8: analog Lb

Somit ist ein direkter Anschluss an ISDN möglich, für analoge Anschlüsse liegt für Deutschland ein Adapter auf TAE bei:

  • Pin 1 RJ-Buchse auf Pin 1 TAE
  • Pin 8 RJ-Buchse auf Pin 2 TAE

Ein normales Kabel mit TAE-Stecker und sechspoligem RJ-Stecker, wie es für den Anschluss analoger Telefone an eine TAE-Dose verwendet wird, funktioniert nicht.

Bei entbündelten Anschlüssen (ohne analoges oder ISDN-Telefon) kann ein direktes Kabel verwendet werden.

Das Kabel für deutsche Anschlüsse:

  • Pin 4 RJ-Stecker auf Pin 1 TAE
  • Pin 5 RJ-Stecker auf Pin 2 TAE

xs4all voip with Fritz!Box equipment: do not combine Fritz!Box “With prefix” number formats with xs4all “Block international numbers”: it will block non-international numbers too.

Posted by jpluimers on 2021/03/22

If you use xs4all VoIP from any Fritz!Box device, then keep the “Telephone Number Format” for “Country code” on “No”, and “Area code” to “None”:

If you have changed these to “With prefix” like I did:

combined with VoIP settings to block international numbers on the right, then when you dial a number outside your area, you will get a friendly voice telling you “this number is blocked”

On my research list: connecting Fritz!Box devices together into a virtual PBX

Posted by jpluimers on 2017/09/29

I’ve some Fritz!Box devices on various locations that each provide VoIP access and either ISDN or PSTN lines.

Wouldn’t it be cool to be able to join them together into a virtual PBX?

I’m not sure how it’s possible and what you need for it, so here are some links that should make my future research on this easier:
