Identify the contents of the T&T box

  • Hello community

    I have had a new house for a year and unfortunately very poor documentation of the electrical wiring.

    Can someone please help me with the photo?

    I have a Swisscom copper connection via a rod and cable. The cable goes into the house on the screed. I suspect that behind the panels under the roof the line then goes into the T&T box in the wall, which I took the photo of here. One floor below the box is the Swisscom Anschluss for the Ethernet cable.

    Are my assumptions correct? Unfortunately, I have never seen connections like the one in the photo.

    Thanks in advance for your efforts.

      Hello Darth

      Yes, your assumptions are correct so far.

      By the way, the part in the photo is called a coarse fuse and must be used if an overhead line leads into the house.

    Hello @Darth

    He meant a rough backup, but this copy is already very, very old…

    The new coarse fuses are narrower.

    In the event of a malfunction, this fuse is usually replaced with a new one.

    And what kind of overhead line goes to your house?

    But you still have ancient cables from your fuse to the DSL socket, which can cause disruptions. But again it plays a role what speeds you should get according to the checker.

    And what you effectively get. You can still optimize it.

    But without precise data you cannot give precise information.

      Thank you for your answers and tips.

      Lori-77: The overhead line looks like an electricity pylon in a developing country - the USA for example 😉

      At Swisscom I was able to use the network information map ([https://www.swisscom.ch/de/business/netzbau/Netzauskunft.html](https://www.swisscom.ch/de/business/netzbau/Netzauskunft .html)) also find the confirmation.

      Fortunately, the line comes from the neighboring street and not from our private road, which means that the street doesn’t have to be torn up if something were to happen - in winter, according to the forecast, we will get fiber optics.

      Then at the latest I’ll have to worry about the old fuse and the cables. Maybe there’s even a house connection…

      The speed is ok. Technically only 30 MBit is possible - I get that too. But I pay for 50 MBit because that is the smallest contract. That’s just how it is at the moment.

      An upgrade to “FTTS/B Neubau” was announced for the winter. Then I’m at 400 MBit.

      Quick question: What does “new building” mean in the announcement? Does this refer to the extension (i.e. the street is being rebuilt/torn up?) or the house? The disadvantages of FTTS/B are clear (last copper mile). Only the new building confuses me a little.

      Best regards
