VoIP.




Of course it won't. But what you're describing is dinosaur technology
even compared to telephone equipment that was modern 20 years ago.


It was dinosaur technology. But guess what, it worked. If it ever quit a
good spritz from the contact spray can would make it work again ;-)



Well, sometimes you needed to get a spring bender out, and adjust the
tension in the stack up a little, but that was about it... 8-)

Yet another by-product of a throw-away society. Almost everyone is
conditioned to throw away and replace if it breaks; and then are surprised
and confused when competent engineers insist that this is not acceptable
for some particular application.


POTS technology is actually the opposite. One telco technician told me that some of the installations that he had wired up as an apprentice were still there and in full service when he retired about 45 years later. Oh, and the phone in our kitchen is vintage 1927. Still works like a champ. The only TLC it needs is the occasional wood polish. And don't try to hang one of these on drywall. It sure ain't one of those plastic VoIP gizmos ;-)



I worked for a supplier of mobile telephone equipment for the military. The design goal was for a minimum serviceability of 25 yrs. This included mobile shelters which served as branch offices as well as portable hand helds. We even did a lifetime buy of components to service the equipement. I wonder if it has survived the cellphone age?

I remember helping hang several 'new' shelves of switches, with dates on their frames of 1938 (this was in '86) and most of the wiring was cloth insulated! That stuff was never destroyed, just recycled to somewhere with less technology!


In the army the truck our unit was assigned was 20 years old, had non-synchronized gear, the jake brake required standing on it and what they called power steering back then required muscles. Yet it looked brand new. So I asked the guy from which I was taking it over, how come? He said that when he took it a year before it was delivered with zero miles and the protective wax cover had to be removed. Talking about "new old stock"...
