OP. Hopefully you're getting somewhere now, albeit slowly, if no progress is made then perhaps a second line is the answer.
From what I can glean above, no amount of lines ordered will help the OP acquire FTTC ??.
It reads to me (and I've seen it happen a few times myself), is that the whole DP has been accidentally missed, when extending and jointing the D-side cables into the then newly positioned FTTC Cabinet.
To try and elaborate, the planner (using various electronic systems) will have done his bit and captured 'x' amount of DP's worth 'x' amount of potential customers, in his job-pack. He will then locate the best place for the new Cab to be placed, usually within approx 50mtrs of the existing copper Cab.
Once in place, the distribution cable jointers then identify the relevant DP cables that have been planned, and extends them so they go into the new FTTC Cab in order that we can then cross-connect the VDSL service when an order is placed.
As mooted above, the issue that can sometimes happen (albeit rarely), is that a DP gets missed out by accident during the cable-extending task.
There are many cables in these underground Cab boxes, but for the most part it should be easy (ish) to perform the task, as for example ... you may have 5 DP's all worth 20 customers, so this will manifest itself in the underground Cab box as a 100pr cable. This then gets extended into the FTTC Cab and formed out so each DP runs concurrently down the strip. There may be 2 DP's worth 15 & 20 customers on each, this will manifest itself as a 50pr cable in the underground Cab box and the format will be the same as the 100pr.
It's when you get the odd DP worth 5 customers etc that is fed via its own single cable from the underground box, that a mistake may occur.
Not trying to make light of your plight here, just trying to explain the process and how human error can creep in ... and to point out your road will not need digging up, it simply needs your underground cable extending in the underground Cab box and presented into the FTTC Cab.
I hope this makes sense, if not please say and I'll try to put it further into layman's terms. Cheers.
