For anyone interested now or in the future, Openreach have installed and commissioned a new PCP & DSLAM for some EO lines on the Beamish Exchange (NEBEA) as part of Digital Durham's BDUK project, it's been numbered up as Cabinet 11 and I think it serves mostly lines that were listed on Exchange 3.
Serving mainly High Handenhold, High Urpeth and Outlying Dwellings though it is possible that some of Beamish itself is covered too.
Timings were roughly:
PCP Cabinet erected around 26th August 2014
DSLAM Cabinet erected, power, ducting & cross connections installed 11th - 15th September 2014
Cabinet Number 11 lettering applied sometime in October
Exchange lines shifted 11-12th November 2014
Openreach Where & When Checker updated 20th November
I had confirmation from Digital Durham today (21st November) that Openreach have completed the installation and barring any last minute hitches Ordering should go live in the next 3 weeks.
Hope this info proves useful to others.
Meanwhile I shall be cmd+r'ing on dslchecker.bt.com awaiting the magic to happen.
