Hmm, not sure about the tubing (colour) as all I could see was that they were pulling something through the ducting, using a long blue cord. I saw this earlier this year when they presumably where installing FTTC up Tyler Hill. Same sort of large van as well, was being used.
However, on this spreadsheet
It seems to suggest that 20% of lines on the cabinet for CT27LN will be FTTC enabled. However, this spreadsheet is December 2012, so I doubt the cabinet will be ready in the next month or so, I can only hope. But it does look like some lines will get this year now to hope mine is one.
