Lots of new builds round here. As I was passing some of the houses this morning I noticed two grey boxes on the front wall, both about 20 cm above ground level. One was about 15 x 10 cm and 2 - 3 cm deep, was marked "Openreach", and had a black cable entering it from the ground. I assume this box was for FTTP.
The other one, near to the Openreach box, was of two types. The first was about 12 x 12 x 3 - 4 cm, and the second was about 18 x 18 x 6 cm. There were no cables or markings. Both were a slightly lighter grey than the Openreach box.
What are these boxes for, and why the different sizes, which was not related to the size of the house they were on?
