I feel your pain.
I'm connected to (and within 50 metres of) PCP 33 (bottom right of picture).
According to LondonWorks there are no scheduled activities in this area before 31/03/2012 (the latest revised date for FTTC).
PCP 28 has apparently (according to the Openreach engineer) been 'LIVE' since 09/2011.
Frustratingly, both PCPs had 'DSLAM' painted on the pavement adjacent to them on the same date in April 2011.
Naively, I hoped that Openreach would just add another 50m to my distance from the cabinet and re-route my telephone line to PCP 28 (I believe the underground ducting has been there since last century!).
Sadly, that doesn't appear to be the case.
I'm almost (but not quite) tempted to go for Virgin Media.
