His FTTP (the person in that thread) was rolled out in 2017 or even earlier.
Edit: 2018 or earlier.
This example was 2017There's a very large number of properties who show only 330 available that aren't connected to ECI hardware.
Usually it's just a database error. The same type of database error that's showing 1000Mb to some on ECI hardware.
Sometimes it's a backhaul/cablelink issue restricting speeds.
All OpenReach FTTP deployed in the last couple years will be on Huawei or Nokia OLT's (or even ADTRAN).
The only people who are unlucky enough to sign up to FTTP and end up stuck on ECI hardware are those on older FTTP rollouts.
Nobody who's waiting on an FTTP rollout should be worried about ECI limitations, fortunately.
