hello,
asking help from Network gurus.

facts:
house with 3 phone outlets - FTTN
was with TPG ADSL then TPG NBN then Belong NBN - all from Outlet 1.
now with Spintel FTTN since Oct 2022 also from outlet 1, no issues, very smooth churn processes. no downtime.

last week i moved my modem (it was modem + router in bridge mode), from outlet 1 to outlet 2 - just temporary.
again, no issues, just replug everything, restart and all good in 5 mins.

2 days later i moved my setup back to outlet 1.
all same cable etc.
now at outlet 1, i dont have Sync on my modem. already waited 30mins, already did reset modem.

Spintel said they deceted Bridge Tap on my premises, ask me to call electrician to remove all the taps, and then call NBN Co to restore my connection to outlet 1.

is the above suggestion by Spintel in the correct way?

one thing i dont understand is why i could move from outlet 1 to outlet 2 without issue but now cannot go back to outlet 1.
thanks. and yes i need the modem to go back to outlet 1 if possible.

    It's solid advice. The bridge tap is what allows you to have more than one outlet. But as to why the initial port suddenly stopped working, that's weird.
    The fact that it works to any port though means it is 100% internal wiring, ie. your problem to deal with.

    I had constant issues with ABB if I swapped routers or similar - the auth servers didn't react properly and whilst I could get sync, the auth server wouldn't authenticate. I'd have to call and force a reset (more than I could do via the app) then it'd come fine within a couple of minutes while still on the phone.

    Assuming it's a detected tap, that's an easy fix - just isolate the two wires behind the outlet and remove the second run to outlet 2, once you know which is the internal and which is to the street.

      Uhmm.. im not that confident to dig behind walls and play with cables… but then fee for electrician could be $200+.. duh….

        It's only two low voltage signal wires, and your NBN already isn't working so you have nothing to lose by cutting the tap wire off.

        Worst case it still doesn't help then you can call a sparkie to have a squiz - but if it works you've saved $200 and a week of waiting for someone to turn up!

          my NBN is working fine now via outlet 2 right now.
          it was working at outlet 1 for months, then i need to rearrange some furniture's so i moved to outlet 2 for two days, all good. then when i moved back to outlet 1 the modem didnt get Sync.

          i moved back to outlet 2, all good. but i need to return to outlet 1 if possible.

        You need a registered cabler to carry out the work, as its telecommunications.
        Plenty around.
        Also for FTTN you are only meant to be using one Outlet per connection. Its not like FTTP where you can have multiple providers configured at the same time.

        The only exception to this is where you have more then one business or apartment in the same building where NBN Co will run multiple services.

          i see … only today i know that multiple bridge tap is bad for FTTN

  • Twix on 10/01/2023 - 20:34

    Contact some cablers on here. Ask them to replace the first phone wall socket where your VDSL2 modem is and disconnect the bridge tap from the two extra phone wall sockets. You don't call nbn to restore the connection to outlet 1. Outlet 1 should start working when you plug in the VDSL2 modem. If it doesn't call your ISP to get nbn to come out.

    Is outlet 2 working at all?

    • CyberMurning on 10/01/2023 - 21:46

      Yes i was like moving the modem between 1 and 2 at least 3x while trying to troubleshooting then gave up and leave everything at outlet 2 (outlet 2 is fine, when i plug cables and restart modem i get sync light blinks and then steady in just 3 mins)

      We have not used outlet 2 nd 3 for years… (we stop the landline since 4-5 years ago)

        Your NBN phone service will be delivered over Voice Over IP as others have said.
        If you want a service that has some sort of redundancy on NBN you need to go for a business grade service with 4G or 5G failover / backup or on the home / residential front Optus and Telstra are the main two that I know of that offer this, but with the home connection you don't get a static IP but you do with the business grade connection and the IP will float between your NBN Connection and the mobile broadband backup.
        So it all comes down to how important your internet and communications are.
        Oh you will need a UPS, uninterrupted power supply as well for when the power goes out if connectivity is important.
        Cheap version of all this is to just use your phone as a hot spot.

    Question.
    If i do this bridge tap removal, meaning the other 2 outlets will die, right? Hmm i rather keep them alive just incase one day i need a landline i can just plug in the cable.
    But this case isnt possible while having NBN? Or just because FTTN?

      There's no more landline once you move to NBN

    • Twix on 10/01/2023 - 22:18

      The extra 2 outlets will no longer work and your FTTN sync speed can increase. You don't need to keep the extra outlets. The home phone runs off VoIP over the internet.

    • Morien on 10/01/2023 - 22:30

      Yes, Remove the bridge tap. It's bad for NBN.

    ok guys now i understand bridge tap is bad for NBN especially FTTN.
    not sure why the first outlet suddenly stop working (Was working for like 5-6 months) but i will decide to get the bridge removed sometimes, and in the mean time will run a phone cable from outlet 2 to a place near outlet 1 so i can move my modem back to the original spot where my NAS and TV are there - must connect with RJ45 (lucky it is just short of 5 meters away)
