I just wondered if, given the state of BT's copper/ aluminium wiring, a nearby fibre installation could, even in theory, have unwanted effect on one's ADSL (any variety) connection.
I am making the assumption that both locations' pairs are in same bundle.
-
Yes, you are absolutely correct.
That is one of the reasons why a degree of 'power cut-back' is employed at a cabinet DSLAM, so that the relatively weak ADSL(2(+)) signals are not swamped by the VDSL2 signals that are injected, from the FTTC, onto pairs in the PCP.
-
a ofcom research document suggested the long term affects are benificial to adsl as the power cutback tends to be more than requires so the weakened vdsl signal is weaker than adsl signals so as people upgrade from adsl to vdsl the ones left on adsl see improvement.

That seems to say that being the only adsl in the village might not be that bad. :D

This seems to be near my state and certainly I don't seem to get the big spikes in S/N, but it still drops at night
