Transition DSL to fiber optic

    • Hello community

    The development with fiber optics was planned for our terraced residential property (11/25 parties) in the summer of 2022. The development document mentions XGS-PON, we are located about 350m from the DSLAM and in December fiber bundles were pulled into the technical rooms. For us - so the Bau-Chnuschti said - there are 48, which goes well with 4×11. I assume that the development happened from the street box.

    This evening I looked at the well-attended articles on expansion stop and on [glass fiber expansion](https ://community.swisscom.ch/t5/Internet-Allgemein/Glasfibrillausbau/td-p/592726) granted. Forgive me if I didn’t find much in my search…

    • Does the technology (AON, GPON, XGS-PON) dictate whether P2P or P2MP has been built/planned?
    • I assume that there are already enough WEKO-compliant fibers available in the DSLAM. Otherwise they would probably have planned/excavated/developed in a more convenient location between the lawsuit and the verdict.
    • A neighbor said during Christmas week that things should continue in January.
    • I assume that the development is in accordance with the BGH. Do you share this assessment?

    And should the fiber really be laid as soon as possible in January: How does the transition from copper to glass happen:

    • Switch from copper to glass on deadline X.
    • Overlapping operation for a transitional period.
    • Permanent backup from glass to copper if something goes wrong.

    I consider the third point to be rather unlikely, since the cable harnesses were hidden in the same pipes and the continued existence of both technologies would probably be too cost-intensive. In any case, the Khnushti thinks that the copper stays in the ground.

    So consciously a bit of speculation, I look forward to your facts!

    Greetings

        No, it certainly didn’t

        Then he knows more than we do

        You can’t say that the 48 is simply the cable chosen for the size of the house and it is enough to implement at least one plug per apartment with P2P.
      • Switch from copper to glass on deadline X.
        No, but possible at any time from a deadline
      • Overlapping operation for a transitional period.
        Yes, but always either or, not both. If you have the IB with xgsPON SFP plugged in, then you can leave CU plugged in, but it will only connect to fiber. IB4 no longer has DSL Anschluss.
      • Permanent backup from glass to copper if something goes wrong.
        No, copper will be switched off at some point (e.g. when the mCAN can come out). The options have already been explained here.

      Although I consider the third point to be rather unlikely, since the cable harnesses were hidden in the same pipes and the continued existence of both technologies would probably be too cost-intensive. In any case, the Khnushti thinks that the copper stays in the ground. For now, yes, but we’re on it.

      Some feedback above in bold (yes, ate too much over the holidays) and in italics (and drank too much).

      And why do you call the person who brings fiber optics into your house “Chnusti”? Not nice.

    @andiroid

    What we can do here in the forum is speculate what will happen to you, nothing more and nothing less. If you really want to know what’s going on, then you can go via the “entry path” on 0800 800 8000 and ask the network construction department there and they will answer your questions specifically for your situation.

    @hed: No, no. There is no need to speculate. 😉 If someone in the near past - according to the WEKO saying - still got the fibers, or helped friends or acquaintances, that’s enough for me to tame my Gwundernose.

    That’s why I don’t bother support unnecessarily. But I could ask Sam, that’s a fun idea!

    Hello @andiroid

    Until now, the customer received a message that his fiber optic Anschluss was active.

    As soon as the customer has connected the router to the fiber optic and activated it, the DSL will be deactivated.

    I still know that customers who had fiber optics installed and who still had copper were switched to fiber optics and then the DSL was dismantled. This hardware is then not needed, saving costs and also electricity.

    Hey @Lori-77! Thanks for the tip. Of course, it makes sense if the infrastructure on the network side is also dismantled. But that will hardly happen in 0, nothing… 😉 I completely understand that. The cable-layer-Chnuschti mentioned that the cables were left lying there, which I can ultimately understand…

    So I assume that the migration happens instantaneously. It would have been nice if, for the sake of simplicity, both media had continued to serve for a while, that would have reduced the “stress” in the transition phase a little… 🤨 So I’ll adjust to that. 👍

    Äs Greetings

    This usually doesn’t work without interruption, but you can use a mobile bridge to bridge the gap.

    Yes, that would be an option for which I would need temporary hardware and even more configuration effort. But yes, if you really depend on continuity, definitely an option.

    The IB itself offers the option of connecting a mobile to the USB.

    Ok, I didn’t know that either. The IB will probably only serve temporarily. Depending on the pending tests described here. And their place is in the basement in the rack and reception there is limited or even impossible. Maybe for others it is - not an option for me.

    My multiple experience is that it is uninterrupted….

    Exactly as described above by colleague Lori-77…

    @POGO 1104

    I wouldn’t expect that, for me even switching to g.Fast resulted in an interruption of almost 2 hours.

    @POGO 1104: Oh yes, the details… 😝 I understand the @hed when it has an interruption when it is switched “at the back” from xDSL to g.Fast. Other HW on the same copper cable. But as you rightly insist, when switching from copper to glass, the “logical” switch should/should happen relatively quickly.

    🤔

    I fear that my tinkering will cause a much greater disruption to certain services. Hence the original question…

    When XGS-PON was activated in the interim phase, I contacted my provider (Sunrise), they started the migration process and I received a router.

    Then Cablex came and installed the box and I was able to put the fiber optic connection into operation.

    DSL continued to run in parallel and was only deactivated 14 days after stable fiber optic operation.
    In that respect it was suitable for me, but I had to be proactive about it.

    I don’t know how it’s handled at Swisscom.

    @andiroid

    Even if it should work without interruption in your case, I always prefer to anticipate the worst case scenario and prepare accordingly if the Internet Anschluss is so important that you can’t do without it for a while.

    Show original language (German)

    @hed You’re making a mistake because of the interruption. When migrating to an mCAN with g.fast, the copper cable must be interrupted. Therefore you have an interruption. With FTTH, the copper line remains active and the fiber optic cable is pulled in parallel. At some point the fiber optic is activated, usually when the customer orders a tech change. Then you have two active Swisscom access networks at home. If you now have an IB3, you will receive a fiber optic set for the IB3 when you order the Techchange. Now you can simply pull the copper cable, plug in the fiber optic module, connect it to the OTO socket and you’re done. The router is the key to the service network and it is already personalized for you on copper. If you want, you can now even go back to copper and back to glass and back…. Conclusion: The interruption is as long as it takes you to connect the router to the other socket 😉

    @5018 I can confirm that. I once had a case in the field where a tech change was made to fiber.

    The customer connected the router with fiber optics and also left the copper Anschluss in the router because of the telephone feedback.

    Error message from the customer: I keep getting the error message no internet connection when I want to watch TV with 2 TV boxes.

    Copper Access 20 Mbit/s Fiber Access 1 Gbit/s

    The error was that the router couldn’t decide which line to use (fiber or copper).

    Hey Roger!

    Thanks for your explanations! Enlightening for me, I hope that others can benefit from this too! It helps me to be patient first and wait until further expansion can/will happen. 😉

    The neighbor also only spoke to the construction crew. In this respect, I understand why the false information arose! 😣

    I think we’ll leave this thread as it is. I will then publish an update at a later date…

    Welcome to the club! 🍷🍾🥂 & 🥩🍝🫕 And thanks for the scene humor! 😁 Here’s the scene applause! 👏

    And why do you call the person who brings fiber optics into your house “Chnusti”? Not nice.

    Really!? Thanks for the feedback. But it really wasn’t meant that way! I have respect for those who have to lay “my” fibers outside in the drizzle in December. With Khnuschti I just want to emphasize that the information came directly to me from the worker/executor on site and not from the general contractor or the subcontractor. The Idiotikon even proves you right. It has a rather negative connotation - although “gnarled, burly […] boys” describes the type quite well. My 1.71cm height would make me weak before my lunch break and would definitely feel more comfortable in a heated office. Him: Khnushti. Me: Armchair farter. Everything built in for illustration… 😇 And in no way meant to be condescending! 🙏

    I’ll leave the rest alone and ask Cablex (GU/planner) about the status of things.
