Yes, the line was activated. Speeds were, unsurprisingly something similar to the other line, but a bit slower (probably due to crosstalk).
An engineer came out today, but unfortunately was one of the chocolate fireguard variety (friendly though). He appeared to be one who just followed the training and guessed the rest, as opposed to one of the wonderful few who have a passion for what they do and strive for knowledge.
It's still below estimate though, so it's possible I might get someone who can fix it up a bit yet!
