Only two cabinets required planning permission, both of which were approved. These were coloured dark blue. Tim coloured all the "new" cabinets light blue. The only two of these requiring permission were in Old Basing because it's a conservation area.
The old cabinets will not change, a new cabinet will be installed within 100 metres and cross-connected underground. The new cabinets are about 1.5m tall and have a power warning label on the side (old cabinets have no power).
I'm only aware of two new cabinets accepting orders (168 and 199), the others appear to be delayed. All I can recommend is to check using the BT Wholesale site every few days. Avoid the BT Infinity checker because it filters lines estimated less than 15Mbps.
