So credit given where due, it would appear that FTTC installations are appearing around my town. September was the scheduled date and it would seem that this is being adhered to! Admittedly these are the only ones I've found so far while casually walking around the town so I guess there's many more to come. The one on the left still has the factory sticky tape on it.
Interesting enough some are evidently smaller boxes than others. In fact there appear to be 3 different designs (small, medium and large with vents on the front). Of course it's possible none of these are FTTC and I'm entirely mistaken :D

Those are police riot defence huts. ;D
For reference the first image shows a PCP cab on the right and a Huawei 128 FTTC cab on the left. The second and third images show 288 FTTC cabs and the last image is another Huawei 128 FTTC cabinet.
