An elderly lady phoned her telephone company to report
that her telephone failed to ring when her friends
called - and that on the few occasions when it did
ring, her pet dog always moaned right before the phone
rang.
The telephone repairman proceeded to the scene,
curious to see this psychic dog or senile elderly
lady.
He climbed a nearby 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 loudly
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 via 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 phone number was called.
4. After a couple of such jolts, the dog would start
moaning and then urinate on himself and the ground.
5. The wet ground would complete the circuit, thus
causing the phone to ring.
