Connecting a Fritzbox - am I ISDN or analogue?

I have a Sinus 1054 DSL T-com modem at the moment.

The Fritzbox is asking if we connect via "ISDN" or "Analogue".

I have DSL-Lite runnig at 384k. I am confused - in the UK DSL is over "analogue" but I know they always seem to fit ISDNS over here.

OR can you only run ADSL over analogue?

One way to find out migt be to check the phone bill from your service provider, if you have ISDN they will be charging you for it, as it is an extra instead of the normal analogue line charges

Do you have an NTBA? Are your phones analogue or isdn? It should not actually matter though, DSL can run over both, or more accuratly runs in parrallel with both. Are you using the fritzbox as a router through the sinus modem? Or are you replacing the sinus with the fritzbox?

ISDN or analogue (T-Net) has nothing to do with DSL (or your modem). This is your telephone service. Either will support DSL which is a supplementary service using the same incoming cable pair. In both cases you need a small splitter connected to your incoming line which splits the service into telephone and DSL. If you have an analogue phone then your phones (or phones in your house) are connected directly to the splitter. If you have ISDN then an "NTBA" is connected to the splitter (the NTBA is small white box about 10cm x 5cm x 3cm with a single green LED in the front) and your ISDN phones or devices connect to the NTBA.

If you are connecting a Fritzbox (depending on the model) then your phone service (after the splitter) routes THROUGH the Fritzbox. It doesn't need to know which service you have to work, but it does need to know if you want to merge VoIP calls and normal calls onto the same end-devices

You can run DSL with what you like, it happily shares the same piece of copper. For a while Telekom forced everyone who had DSL to take ISDN (what I've got) but technically there's no reason for this. For ISDN with Telekom you have a box with ISDN written on it. To be sure phone them up.

ah the stress! Frtitzbox is connected and rather wonderfully seems to be runninng quicker for my internet connection. Passwords etc all correct. Easy.

However when I plug in the phones I do not get a dialling tone, but a beep beep more like an engaged tone??

Its tricky because it has to be all or nothing - as the Fritzbox connects phones AND internet at once.

Have you set up your phone account with the DSL provider ?

Grrrrrrrrrrrrrrrrrrrrrrrrr.

So I got the impression that the Fritzbox would allow my regular phones to work as before - just by plugging them in via the connections provided (1, 2 and 3). But I only get the engaged tone.

Do I need to programme the Fritzbox to "see" these numbers? or does it ONLY work for VoiP???

Aha - any idea how I tell it to do this? A this stage I just wanted to get my phones and internet connection working as usual, and then play with VOIP later.

But in an ideal world I would tell it to MERGE both sytems into the one on the same phones. It is the 7170 model.

Is there a magic word for "merge calls" I should be looking for?

Assuming you have an analogue telephone line (did you work this out yet?) you may be missing the wire (TAE-RJ45 cable) from the splitter (or previous telephone point) to the Fritzbox to route your current connection through the box. The 7170 model uses a "Y" cable to route this, which is quite confusing, so one end of the "Y" goes in the bottom (DSL) output of your splitter and the other goes into the telephone jack (again, assuming an analogue line) using an appropriate TAE-RJ45 adapter (delivered with the system). The tail of the "Y" goes in the "DSL/TEL" socket on the Fritz

YorkshireLad. Yeah 99% sure it is all connected correctly.

I think I am stuck on TELLING the software what is connected to "Fon 1" etc. Where it says Festnezrufnummern I am not sure of the format?

Should it be 08232888888 or 8232888888 or +448232888888 etc?

I have ISDN but analogue phones like most people, so I asume I still select ISDN-Anschluss?

Do I tick auf all Rufnuumen reagieren. I assume I just need 1 Rufnummer der Nebenstelle selected?

Man this stuff is bad enough in English but in German it is like working in code!!!

If you have ISDN it is important to know if you are connecting directly into the NTBA (in which case you setup Fritz as an ISDN connection) or if you are connecting to an analogue line off an ISDN-Analogue converter or ISDN phone exchange (in which case Fritz needs setting up for an analogue connection).

Both ends of the Y splitter are connected into the same "T-DSL" box, right next to each other. gonna try and grab a photo 'cos I have 4 boxes in total I think!

Can you do a screen capture of the screen where you enter the phonenumbers ?

If you have ISDN, then this is wrong... One end should go in the (bottom, right) outlet of the splitter, then other into one of the (2) outlets on your NTBA which should be nearby...

Check out the section of your manual "Mit dem ISDN-Anschluss verbinden" which has a visual of what YL6 just posted.

So as you can see the FRITZ cables are now plugged into the box on the left, and the one on the right is now redundant. Is this wrong?

diagram on the box dont help much

I have ISDN (Telekom) telephone and DSL (!&!) with A Fritzbox and everything works OK.

Do you still need help?
MT

then i have these on the other side

Obviously with ISDN I have 3 numbers and when I originally set up the Fritz box I didn't bother with the Fon 1, 2 & 3 number definitions. I just connected my telephone to one of them and all 3 numbers worked to the one telephone.

Since then I have set some definitions as I have separate telephone and Fax.

Hmm looks like the Y cable has an analogue connection for the phone, can you plug that into your ntba? (box on right). You might need an adaptor or another cable. Whats the thing the phones used to plug into? I guess thats what enabled you to plug your analogue phones into the isdn line. Maybe you can still use that between the fritzbox and the splitter, but I suspect an adaptor is required that lets you plug the fritzbox directly into the ntba. But lets see what yl6 says...

YL6 says there are too many cooks spoiling this broth, some of whom are guessing, so he or she will sit back and watch the fun...

Good idea.

Also sitting back as my configration is totally different to your picture.
But it works.

Not saying anything else until asked.

Yeah I admit my last post had a fair amount of guesswork in it, just wanted to see if my guesses were right, I will shut up now and see once yl6 has had enough fun.

I agree... and I've got a FritzBox.

Well if anyone could actually identify what the bits are called that would help!

I have 4 boxes in total (fuck only knows why).

I know the ADSL modem is the one stuck to the wall with the antenna - and that is a "bin" job under the new system.

But the other 3 are confusing me. In theory they are an NTBA, a DSL-Splitter and summat else.

On the box it says:

für ISDN-Benutzer: NTBA zwischenschalten

Hey JE - Why don't you use your new fangled digital camera thingy and post the pics of the bits you have?

Then we can be just as bloody useless AND have pictures.

Sin - already placed pictures on this thread.

Right - just googled.

The white jobbie on the right is the NTBA which is not being used at present, so according to the product box I need to "NTBA zwischenschalten". Which means stick it between the Splitter (on the left) and the Fritzbox.

Hmmmmmmmmm.

The black end of the Y has a telehone style connector, and the NTBA only takes RJ45s.

But the NTBA connects to the Eumex 520PC (whatever that is) which currently feeds the phones from 3 points. so do I plug Fritz into the Eumex 520PC???

Thanks mate. I would never have noticed without your help.

Looks like you've got the same white boxes like what I've got.

Alright, this is educated guesswork, since yl6 hasnt answered it yet (perhaps he doesnt know ) but try plugging the splitter into the wall, and the grey connector of the Y cable into the splitter. Then plug the NTBA into the left hand socket on the splitter, then plug the summat else, into the NTBA how you used to have, and plug the black connector of the Ycable into the summat else, where your phone used to go. For this configuration you set the fritzbox to having an analogue connection.

I've just had a look at my boxes, and they look alright to me.

Going backwards from the FritzBox: On the back of the FritzBox there are 4 connectors. Looking square on to the back, an Ethernet cable should come out of the far left connection and go to the connector on the T-DSL box marked 'NTBBA'. The second connector from the left is a direct Ethernet connection to a secondary computer (I use the WLAN). I don't use the third connector, and the fourth on the right hand side is for the power connector.

How are we doing so far?

Internet connection is all Dandy Sin s- that is not an issue.

sounds like I might need to plug the black Y from the Fritz into the silver T-Eumex 520 dodah, which normally takes my 3 phones, and then plug the phones into the Fritz.

Choice of 4 sockets into the silver Eumex which hardly helps. Turning into a joke install this.

I hope this helps.
If not, sorry for the intrusion.

My three (ISDN) numbers are in these 1, 2 & 3.

Malt-Teaser.

Malt-Teaser is essentially correct, although his cabling plan refers to a different Fritzbox and splitter to that JE is using. The 7170 has a "Y" cable that combines (in his picture) the purple and green wires into a single outlet of Fritz. The grey end goes to the Splitter (in JEs case the outlet on the front panel as he has an older type of splitter than MT shows), and the black to one (any) of the two outlets at the bottom of the NTBA. The third end goes to the (grey) "DSL/TEL" outlet on Fritz. Next to this outlet you connect the 3-phone combiner ("FON 1-3") and connect up to 3 analogue phones to this using standard german TAE jacks. Any ISDN devices previously used and connected into the NTBA should now be connected to the third outlet ("FON So") and should work as before.

You'll be needing a Birmingham screwdriver for this job JE.

Don't force it, get a bigger hammer.

This is where it alll goes Pete Tong.

Bottom of the NTBA takes RJ45 stylie sockets, whilst black part of the Y cable has a German telephone style socket. They refuse to breed of course.

So do I therefore need to:

1. Get an adaptor to convert the telephone end into an RJ45 on the NTBA?

2. Plug the telephone end into the T-Eumex 520 shiny thing (whatever it is)?

3. Upgrade the NTBA - do newer ones accept telephone style plugs.

So sounds like I might need one of these jobbies then???



This has been like being given an IKEA kit, missing an essential part and with instructions in the wrong language.

Do you need one of those?

I have something which looks similar, but it has two of the German telephone thingies to one RJ45.

MT.

You could tell us the Fri-thingy model number, and provider, and then one of us could get the Geman handbook and tell you the definitive answer !

You SHOULD have a black and grey Y-cable with 3 RJ45 connectors on it, and a separate TAE-RJ45 adapter for the case (only) where you are connecting to an analogue service. See page 12 of your manual for a packing list. Does your TAE "socket" come off the cable?

Keep up. It's a 7170 (Post #9). The provider isn't relevant at this point as he's already got the internet connection to work (Post #6).

I have the same Fritz box as JE but he seems to have received a slightly different version of the software. As YL6 said he should already have all the connectors.

Aha! I am a spunk bubble - its official.

On closer inspection the naughty TELEPHONE style connector is detachable - leaving just the RJ45 we need.

So just plugged that into the BAT box and we are in business - phones ringing, dial tones etc.

However I know need to configure 'cos all 3 phones ring one the one number including the fax etc.

YL6 - do you think there is ANY hope I can get sipgate VoiP lines working Its a scary thought???

Johhy,
as I mentioned earlier, if you don't want to separate numbers to devices, don't define anything in the Fritz software.
That's how I originally had it and all numbers worked to any port.

MT

Nope. Yer not an Official Spunk Bubble until I says you are, and seein' as how I've had to scream at a FritzBox for a few hours before, I think you only qualify to be a mere techprat like wot I is.

Just like I said. Patience and Yorkshire Savvy is all that is needed.
Sipgate is a breeze if you got this far...

This looks like the baby then:
