@daffy2 in the photo you can see I52 cable, not U72M!!!. I52 cable can have a lot of attenuation, i.e. less speed and also be very susceptible to interference (crosstalk). G.Fast has frequencies of up to 104 MHz on the DSL line, which is the VHF radio frequency. The cables photographed are unspecified and unsuitable for this purpose. It’s best to have the cables replaced; the flat rate from Swisscom (CHF 195) is usually covered by the landlord (please clarify in advance).

The whole installation is called BBR installation. (Broad Band Ready).

@POGO 1104 + @user109 - thanks for the info!

Is it correct that all of the cabling, from the Swisscom FTTB box (in the parking garage) to my socket, needs to be updated? That should be 30m across the development.

Are the following magic words suitable for the administration: "The existing cables of the telephone system are not suitable for the ultra-modern FTTB box from Swisscom in the parking hall. This leads to a rather poor connection quality to the Internet, with connection errors, which is particularly common in times of home office - A BBR (Broadband Ready) installation according to Swisscom’s specifications cannot help.

Where does the administration order the BBR installation? (In theory, my administration should know this, but practically speaking, I sometimes think there are some things they don’t want to know.)

And if the administration closes its ears - can I order the BBR installation for a flat rate of CHF 195 and, if in doubt, pay for it myself? Where?

@daffy2 You can order the BBR installation via 0800 800 800. I hope the supporter comes with what you mean. Unfortunately, not all people are tech-savvy as they should be. A technician from Swisscom (Cablex) will come and replace the cables and issue you an extra invoice that you can easily pass on to the landlord.

Only the route UP (house connection) -> telephone socket router (apartment) is swapped. Incl. telephone socket (T+T83) on RJ45 Anschluss (purple).

Thank you everyone for your contributions!

I look at what the administration says, because in principle they have to approve the change through the BBR installation, even if they themselves couldn’t get around it anyway.

And then somehow it continues at some point with BBR and the FTTB box. 🤔

Ouch… no advice is of any help here at the moment 😞 You were able to successfully fix the BT and I don’t see any measurable problems, but unfortunately this only resulted in 10mbps more in the DS. In the US I even see a little less speed.

When I look at this setup, only a handful sync on g.Fast (shocking). But then they’re pretty okay. The cause of the problems lies in the poor and very old wiring that was used at the time. I also see some corroded contacts, which significantly degrade the signal. So it’s entirely possible that everyone else’s problems and disruptions also have a negative impact on your line. The location is simply bad 😞

From the looks of it, no one will invest anything to improve the copper connections anymore. It is clear that people are more likely to wait for fiber optics here. But since it is a g.Fast FTTB location with 500+mbps, this will be at least. It will be another 1-2 years before we see glass in the apartments there.

My suggestion would be that you - or even several tenants - get in touch with the administration with the aim of having a technician in the building at least fix the UP, i.e. clean it, possibly insert new terminals, etc. replace cables It’s probably not possible, it will be too expensive for all parties. Unfortunately I don’t see any more options 😞

Good luck

    Thanks again to Roger G for the feedback 🙂

    I’ve been out and about for a bit and have now found the plan of my development, see below. The mCAN is circled above (the label has probably slipped); I’m down at “4161”. The distance between the points is approximately 76 m; I think I have found all the connection points.

    What’s exciting for me now is the question of how to get a specific T+T box opened (== 4161?), which is probably the central distributor in the part of the house (for four parties): This looks like a negative Allen key (external hexagon ?), but the edge around it is extremely narrow? From _the_ I probably have bell wire, in the stretch before that I most likely know where it runs in the parking garage (the switches are all accessible under screwed sheet metal profiles under the ceiling).

      @user109 What exactly does “house connection” mean?

      I have the following route: mCAN -> 45m cable -> distributor (parking hall) -> 15m cable -> connector (parking hall) -> 17m cable -> house part distributor (?) -> 11m bell wire -> apartment distributor -> 6m bell wire - > “My can”.

      For CHF 195 I’m happy to take mCAN -> “My Can”. 🙂

      By the way, the installation as a whole looks very clean from the outside - but is there enough space for good cables up to the house part distributor (!)? There is definitely enough space in the cable pipe from the house part distributor, there is also an access point in the 11m, which would make rewiring easier.

      @daffy2 House connection = UP (see picture you took T+T box) from there via the loop sockets (underground car park, apartment)

      Pull a U72M 1×2 cable to your telephone socket where the router is connected.

        @Roger G - I was able to convince the hotline that the “BBR installation” product was available at a flat rate. It also worked out economically - around 70 minutes of working time, material (at B2C purchasing prices),…

        The Swisscom technician actually found that “only” around 150/50 came out on the UP (approx. 25m cable length from my socket). In this respect, even after BBR, I didn’t expect things to get better in terms of bandwidth.

        Nevertheless, I hope that I have at least minimized interference from the UP to the apartment; The other bell wires (70m) are mostly behind sheet metal shielding - but still straight bell wire.

        If time comes, advice comes, maybe at some point there will be an improved connection from the mCAN to me (to the UP). I have connection point “1”. Ta-da-di-ta-da-stupid. Hmmm.

        @daffy2: I’m guessing there’s a troublemaker somewhere who’s completely screwing up the DS, because the US isn’t actually that bad. Sure, it’s also impaired, but not as bad as the DS. There’s probably nothing left but to check all the connections to find the culprit.

        But there won’t be much movement towards fiber optics in the near future. The location is already planned because it has glass in the technical room, but because of g.Fast it will probably be a tertiary place on the list. Therefore, we should first get the location to work so that everything runs well. I’m working with the technicians to ensure that we start a comprehensive analysis.

        Given the overall situation (FTTB, ComCo, the local administration, assumed Swisscom quota in the development) I also assume that FTT-my-Dose is in fact less of a priority for *my* Dose.

        That’s why I started exploring and am optimizing from my socket back to the mCAN: my socket => UP 4161 == check (shielded, twisted, no connectors). I still have three segments (three “nodes”, all accessible in the parking garage, which I also have access to) to work on, both according to the Swisscom plan and also according to on-site scouting: D.

        Thank you for embracing technology on your site; I almost suspect that somewhere behind the sheet metal covers in the connections at the nodes there has been a little aging since 1985. Plus: 70m(?) parallel strands and induction on bell wire for quite a few parties in the first 45 meters.

        Based on appearances, I would assume that there are enough empty pipes for all parties, and that the existing empty pipes are even quite large (certainly 20-25mm diameter).
