If by "a few years ago" you mean "in the 1980's", then yes
This 40-year-old technology is obsolete, expensive to maintain, and would be incredibly expensive to replace - for a service that generates declining revenue, in the face of OTT IP-based communication.
That long ago? Maybe in some exchanges, but I still remember in the late 90's the sound of the exchange in the building in what was our general post office, I am sure it was.
But then again thinking about it I had ADSL in 2000 and when it was updated to faster speeds i could not get any faster than 3Mb/s due to the cable going to the old exchange and then back on itself to the new one, so yes maybe the late 80's the exchange was changed here
If you are switching from Openreach to an Altnet, or from one Altnet to another Altnet, then yes you will need a new ONT. However, you will also need a new fibre connected to a different network, so this is definitely not a "self install" - nobody will send you an ONT.
If you are switching between ISPs on the same network (e.g. Openreach to Openreach, or Cityfibre to Cityfibre) then no new ONT is required. The new provider will likely ship you a router which you plug in yourself and connect to the existing ONT. That's no different to changing providers on FTTC.
I realise that switching between an Alt network and open reach network would need a different ONT and a different fibre as they are different networks after all, but I always thought that switching between different providers on the Openreach network would require a different ONT. I heard that from someone a few years ago who changed from one provider to another that someone replaced the ONT.
Oh yes, providers will still push their routers, time that was stopped and either they should ship a router that will work with all providers or tell people they have to supply their own. We had to supply our own modems in dial up days, it was ADSL that started this free modem/ Router stuff.
I don't think you'll find that postings on a forum like this are representative. The vast majority are installed without hassle, and nobody bothers to post about these. Openreach's FTTP network now covers about 9 million properties, with a 27.45% take-up rate, so that's over 2 million happy customers.
Even my sister-in-law had a small problem, first they put the splice box in the wrong place and then connection was lost on the second day, so when the Openreach bloke went back to sort out the connection problem, he moved the splice box to where it should have been.
Who say all these 2 million people are happy?
I was watching a video today of a fibre being spliced, it is amazing how they do that, I know it is a machine, but that tiny thin fibre looks so fragile, and it is amazing how much data is sent down there., it is interesting
Still, maybe the next house you move into will have FTTP and smart meters already installed - and then you won't have to worry about the installation hassle.
I have been here for over 24 years, so unless the other half buy a house in the city, and we decide to move in together which I can't see happening I expect to be here for a while longer
