3: many years back an acquaintance had a billing disagreement with the
local baby Bell (US Worst, if you have to know). In the midst of
this,
Worst decided to show him who had the upper hand by disconnecting his
service.
He figured that since he didn't need the phone lines (being
disconnected),
they would make a perfect test bed for an experiment he had been
pondering
for quite some time. To wit, how many volts do you need to induce
"cross-talk" between line pairs from a house to the CO?
He waited till 3am (to decrease the chance of a nasty surprise to any
neighbors) then he ran his high voltage (non-current-limited) XFMR to
his
phone line (having dis-connected it from his house wiring and
dis-connected the anti-lighting stuff) and plugged it in. The house
lights dimmed a bit for about 30 seconds, then came back full. To be
thorough, he then grounded on side of the secondary and ran both sides
of
the phone line to the hot side of the secondary and re-powered for 30
seconds.
The phone company had several trucks in the neighborhood the next
day...some of the repairmen were asking residents if they saw where
the
lightning had hit.
He did this a few more nights before he got bored and payed his bill,
figuring it had cost Worst more than it had cost him.
What an ass. Someone could have died because he blew out a lot of
people's phone service. BTW, that was a criminal act that would have
put him in jail for sevral years.
Its a pity the high & mighty ******* telcos in the UK all use fibre.
If its all fiber, why did the phone company have to send out a fleet
of service trucks?

When NTL started out they laid fiber just about everywhere, but the street
level distribution is co-ax - the fibre infrastructure means you can't
obliterate their exchange by shoving a million volts down their co-ax.
