Ashton Under Hill exchange is on the list for upgrading to FTTC this year. We are cabinet 3. Is there any way of finding out how many cabinets are part of the exchange as I think they are only going to connect cabinets 1&2 and I'd like to know where these are as well as where ours is to compare.
You can wander about looking for the cabinets. If you're in good enough physical condition to wander around the area on foot you'll probably find them if you keep your eyes open, alternatively you can use Google's images and sit at home. Openreach doubtless have a map, in some form, but they seem understandably reluctant to share it.
The decision on enabling is influenced by many parameters, not least the number of people connected. So even if you feel that location-wise cabinet 3 is very similar to the others, it may be that you only share that cabinet with a couple of dozen houses and that's enough reason commercially to not do it.
