PHONE REPAIR

A Kansas farm wife called the local phone company to report her telephone failed to ring when her friends called - and that on the few occasions, when it did ring, her dog always moaned right before the phone rang.

The telephone repairman proceeded to the scene, curious to see this psychic dog or senile lady. He climbed a telephone pole, hooked in his test set, and dialed the subscriber's house.

The phone didn't ring right away, but then the dog moaned and the telephone began to ring.

Climbing down from the pole, the telephone repairman found:

1. The dog was tied to the telephone system's ground wire with a steel chain and collar.

2. The wire connection to the ground rod was loose.

3. The dog was receiving 90 volts of signaling current when the number was called.

4. After a couple of jolts, the dog would start moaning and then urinate.

5. The wet ground would complete the circuit , thus causing the phone to ring.

Which demonstrates that some problems CAN be fixed by pissing and moaning.



Thought you'd like to know.

Trip, the ringing signal on a North American phone is 90 volts AC at 20Hz:

Yea but its not +90v. The maximum potential is +42 volts AC, which isn't specifically explained in the article. Ringing starts at -48 but AC is a wave, so while maximum potential is 90v, you're only going to get -48v and +42v. So a +90v would be a maximum potential of at least 180v which is within the tolerance of phone systems, however it wouldn't ring. However, voltage doesn't cause pain in creatures, it is amperage. Sorry to take the joke out of this but I went to college for this stuff so It wasn't funny for me. :sour:

Oh, cool! Nah, it's okay; I enjoy learning new things, and the joke is still funny if you remove some of the specific details.

How much current does it take before you actually feel the shock?

I didn't study that. I work in the field of electronics, not the electric chair! But you can feel shocks on low voltages and amperages, however the amount to cause a dog discomfort enough to make sound wouldn't be possible through a phone line. Mostly because of the amount stated, the fact that DC is present, the amount of time that the current is being broadcast for a ring (2-4 seconds)... etc.

Although, as I pointed out before, if the levels in the phone line were enough for the dog to feel pain, the phone system probably wouldn't have worked at all.

Glad you all enjoyed. Iri u r very welcome. Yep, 48 volts. However, I worked on phones and have gotten 48 volt shock when ringer went off (forgot to disconnect) and it was not a day at the beach so to say. LOL
I see some of you got a short course in voltage etc. -:)
Thank heavens this was just a joke above and no animals were hurt during the telling of same!
