Delay yes. But they wouldn't leave an FTTC cab standing idle for 12 months.
Since my post yesterday, a lot of barriers and signs have appeared in a pile next to the cab. I think it's time for the electricity utility to cable it. I believe they have already finished two others on Crownhill and ours was the last to be installed. It is next to the main entrance to Hendrix drive off the H4.
I think that once all the cabs on the estate have been finished they will go live.
Hopefully anyway! Either way, I can't imagine them installing cabs etc. and then not trying to get any return on that investment as soon as possible?
Knowing how it works is completely different to understanding how it works.
