As I've already said, they have an ECI ONT and I have the Huawei.
Regarding smashing FTTP take up, then yes, I expect we do, as the entire area never got FTTC, it went straight to FTTP only, or around 3ishMbps ADSL.
There has recently been lots of what I presume is "infill" activity in the area... It's not uncommon now to see the old and new style of CBTs on the poles around the area now...
Their speeds seem to be around 300 but I assumed at the time that was because I was testing via WiFi 🤔
I have no reason to doubt the engineer, he said he hated dealing with the ECI system as only a subset of people within Openreach can deal with it, meaning he is often on hold when he has to call up their back office to check config or provision a new ONT.
In comparison, when he swapped my ONT, he just scanned the barcode on the front and a minute later it was provisioned and working. "This is so much easier". He seemed to know his stuff and did genuinely care about the issues which I know isn't always the case.
