No trials, native WBC FTTP is a live and active product. The fact you already have the manifold in place is actually doing better than some commercial areas where they are still waiting for these to appear. Note: The black tubing does not contain fibre by default, you need to spot small teams with a compressor blowing the fibre down the various lengths of tubing and splicing it together, i.e. usually under a little tent to keep the fibre clean.
Well we are in a Commercial area and are commercially viable for FTTP (as you already know) and have had all the manifold up our pole since end of 2011 when they started the first 66% fibre rollout.
This year after getting my MP involved throughout July they replaced all the fibre cables used to daisy chain between the Fibre DP's (probably to look busy, was also told there was nothing wrong with the cables and that it was already all done and had been since 2011) and the end of July those new fibres was spliced into all of our Fibre DP's and still no fibre apart from one home, so just because the manifold is all there and also spliced fibre doesn't mean its going to happen anytime soon.
Especially if in a commercial area.
I am not saying that people won't get it, just prepare for a very long wait and possibly get ready to be done in the last 10% of the roll out, and that's if your lucky.
This is what happens when BT bites off more contracts than what they can handle.
