Given that the cabinet has now been provided how can one tell what sort of cabinet one has. Would be interesting to see if the information was accurate.

Also why would some cabinets on the exchange show with FTTC information in the BT Broadband availability checker but mine does not?

Some give estimates long before they go in, others start giving estimates just before or when they go live, just the way it is.

If you find a post by Robertos then he has a website with pictures of cabinets so you can tell what you have.
