On my current understanding - no.
Depends on why they aren't upgrading your cabinet, and whether it will get done as part of a BDUK project. In short there a lot of variables that are unknown still.
I can't see any technical/physical reason for not upgrading the cabinet, and the business reasons to ignore us are (to me, at least) pretty tenuous. Personally I'm of the opinion that BT are simply dragging their heels so they get more of the BDUK/Council money, rather than investing in it themselves.
BDUK funding has been allocated to our area, but obviously I have no idea what is going to be done, nor when. Our local authority seems to be more concerned with hooking up rural areas, and expermenting with satelite tech. I don't know if they've even realised that a decent number of people living in large towns can't get near 2Mbps. There's probably enough of us to skew their statistics, so I guess I'll get in touch and point it out... seems like a no brainer to just upgrade the cabinet, but who knows.
