I outlined their usual methods of trials above. This is trialling
100k ECI lines via ISP opt in.
As mentioned above in both this thread and the other thread.. this usually means that the ISP offers their userbase as whole who are on certain products. Standard procedure is:
- The ISP emails the named contact in the briefing saying they wish to opt in.
- Openreach then [randomly] selects how many circuits they wish to use from that ISP's user-base.
- The ISP can then if they wish ask Openreach to provide them with a list which lines have been selected to be on the trial.
- The ISP can vet this list and ask Openreach to make adjustments.
Occasionally smaller trials are conducted of say just a few hundred lines and in those cases the ISP gets to put forward certain circuits they select, which are usually ISP staff lines.
In view of the fact of the numbers involved for the trial and that it says it is ISP opt in, indicates to me that it is Openreach random selection from those ISPs which offer to opt in. This is why I said ~2 weeks ago that it may be a waste of time asking your ISP to put your line forward if it's an ISP opt in trial.
This isn't a particularly small trial - in fact its probably a good chunk of all ECI lines. I haven't a clue how many ECI lines there are. Last I heard there were ~8k cabs in 2013 and they mostly stopped installing ECI's after 2014.. but lets go wild by saying there are 10k ECI cabs and each DSLAM is mostly full, then that is 200k ECI lines.
