We have done a little digging around, and Arnold is not really rural, but sits on the northern edge of the urban sprawl from Nottingham itself. Misterton in the farthest north east corner of the county fits in better with most peoples definition of rural, but trying numerous addresses we were not able to spot the cabinet in the checkers, so it is possible a provisional ready for service date has not been set. One cabinet in West Bridgford with a date was cabinet 16 which is located on Wilford Lane, Nottingham (example postcode NG2 7RN), this has a RFS date of September 2014, but previously had a date of the end of March 2014 and is part of the BDUK project.
While trying to find the likely cabinet in Arnold, we did spot some roadworks in the area by BT (and numerous Virgin Media ones) that are usually associated with a new fibre cabinet, but all the addresses in the area of this work appear to already have FTTC available (Cabinets 35 and 37). Also Arnold appears to have blanket Virgin Media coverage apart from the area of the University between Valley Road and Arnold Road and one or two residential streets that appear to have FTTC available already.
Update 11:35am We think we may have identified four cabinets in Arnold that might be part of the BDUK scheme (cab 4, 54, 57 and 59 all on the Arnold exchange), including one serving Killarney Park, the small numbers of premises served by these cabinets compared to the previous enabled commercial cabinets making them harder to find. The degree of overlap with Virgin Media coverage is something those chasing the schemes value for money criteria will need to analyse further.
