Openreach's exchange-based approach to announcements is very frustrating to those of us who are connected to an enabled exchange through a cabinet that is not.
My exchange was enabled early 2010, but only 40% of cabinets were upgraded. Openreach has recently revisited the town and begun installing additional VDSL2 cabinets.
The problem is that BT Retail (and other ISPs) have no visibility of this until an in-fill cabinet suddenly goes live; the checkers don't report any predicted availability whatsoever for these new cabinets.
As a result residents are left guessing about when they'll be able to order. Some have seen the new cabinet and attempted to order only to be told that their are "no plans in the next six months" to enable their line.
Those who don't understand the divisions within BT believe that message and give-up. No wonder take-up is low!
