This is very interesting? is this part of the PIA "certification" (Training?) that altnets' engineers end up going through?
(like this:
https://twinscommunications.co.uk/physical-infrastructure-access/#1598921799256-afc152ca-33a5 - though note it covers clearing blockages it doesn't cover repair work from what I can see? unless they cover that off on the new installation part)
Assuming there's limited scope to what works they can do before it gets flagged to BT? I can only go on what I've seen where altnets are rolling out but BT are duct clearing, repairing poles etc. The instances I've seen the BT FTTP rollout comes months after the initial clearing / repair work. Assumed BTOR had been told what was being ran where, and they'd cleared the way so the ducting was usable.
Though in fairness I can only see locations I'm near/have friends & family at. One of the locations an altnet rolled, there's still no BT available at those properties even though plenty of work was done on ducting etc. by BT for their rollout. (Gigaclear, for a rollout in Essex).
Though the houses in question are pole fed for power & telecom (in peoples back gardens....), and I believe Gigaclear are putting Tobys in footpaths near driveways so must be splitting off from the nearest OR point before it diverges to poles?
This is common from what I've seen, where duct/pole work happens when a provider starts using PIA. I get what you're saying that BT are taking the opportunity to use it, but I also think they're maximizing their return on PIA, by making sure altnets can use it.
