Were do they still use that much areial cable? Around here most telco

First of all, there is no classic CO around here. There are fiber to
copper to serve small neighborhoods. As usual, you have your head up
your ass, because Verison doesn't provide any service in this area.

To the best of my knowledge, they are removing very little, if any, of
the old phone lines. The fiber is mostly in new neighborhoods. My
house is served by sort of copper to a CO that was put in some 50 or
60 years ago. Somewhere in the last 30 years they were running out of
copper pairs out this way and they installed a "pair gain amp" which
is a type of multiplexor. As a result, I can't get DSL or even 56K
modem connections. I am lucky to get 28 kbps connections... and yes,
the lines are on poles for most of the mile to the CO. 20 years ago
someone (this city I believe) came up with the bucks to bury all the
phone and electric lines in the main part of town. Otherwise, if the
wires were on poles 50 years ago, they are *still* on poles here.

Let's see. Verizon only started to install FIOS a few years ago.

Another _wierd_tom_ straw man.

Most every wire connecting to the CO is copper.

Bull***. It used to be. They were even even stretched between
wooden things called 'poles', way back in ancient history.

I don't know why you think they don't still maintain the poles and
lines overhead. It costs real money to bury that stuff and I may be
wrong, but I think they have to get right of way to bury the lines.
They did here, but that was downtown where they had to tear up the
sidewalk to bury them.


And for 100 years,
direct lightning strikes to that copper resulted in no damage when a
protector was properly earthed where it enter the building. Michael A
Terrell does not deny this reality.

I deny that Verison or their FIOS is anywhere near my part of
Florida. Not that you know the difference between the various baby
bells.

FCC Part 68 requires this properly earthed protector at both ends of
a phone line. What makes a protector so effective?

Absolutely nothing. The so called 'protectors' are routinely blown
off the sides of houses and out of pedestals in Florida. If you knew
even 1% of what you claim to, you would admit the truth. I have seen the
required ground wire melted after a protector was vaporized.

I agree with that. The protectors will not protect against direct
lightning strikes. That can put thousands of volts on the wire and
hundreds of amps and actually melt the wire. Even a nearby strike can
induce enough current and voltage in a loop to arc through
insulation. I have seen this with my own eyes. No sign of a direct
strike, but split insulation and melted wire at each point that was
near a ground.


I have only seen overhead cables installed as temporary repairs in
the last 20 years. This area started the conversion to fiber over 25
years ago. As usual, you have your head up your ass.

But new installation is not the same as replacing prior
installations. Maybe in Florida they have incentive to bury the lines
because of frequent storm damage. Here the phone company won't even
consider burying lines with their own dime.


Same protection was required as
has been routine in telcos for 100 years to avoid surge damage.

Dumb ***. Lightning does not travel miles to a nonexistent
traditional Central Office. Get your head out of the '70s and see what
is being used these days. This subdivision is less than a mile from
where everything is converted to fiber. You are so out of date you have
no idea how it works, or that the conversion was done because of
constant repairs to Telco C.O. equipment from lightning damage, along
with vaporized pairs in the underground cable. Most of that was over six
feet deep in the downtown areas. You have no concept of reality, yet you
continue to run your ignorant mouth. The last of the fiber conversion
was done to add DSL capability to outlying areas.

I only wish they would replace the CO with smaller, more local
equipment that would support some sort of high speed. You are one of
the lucky ones.
