For those of you not lucky enough to be in a FTTC area, here are a few pictures of the process to show you whats involved...
The first and third pictures show the VDSL cabinet used by BT to deploy its "Infinity" product, in comparison to picture 2 you can see the variation in design and size between a standard size junction box and the new design. Finally, the base under construction is shown in the fourth picture with different duct access points for the power, fibre and cross connect to the nearby existing cabinet.
Hope this is useful!
