How does the payphone communicate to the phone company that a quarter was placed in the phone?

A payphone makes tones to tell the company how much money a person is putting in it. When a person puts in a quarter, it makes 5 quick tones. How many cents is a quarter, and, how many cents do you think each of the tones generated represents?
A quarter is twenty-five cents. Each tone generated by the pay phone represent two and a half cents.
That is not correct. How many nickels make a quarter?

Correct. If the payphone tells the phone company a quarter was put in it by generating 5 tones, how many tones would the phone make when a person puts a nickel in it?
The payphone would make two tones when a person puts a nickel in it.
That is not correct. If each tone is 5 cents, how many tones would a nickel make?
A nickel makes two tones.
How many cents is a nickel?
A nickel is five cents.
OK, so using that information, if each tone represents 5 cents, how many tones does a nickel make?
A nickel makes two tones.
No, a nickel makes 1 tone, because each tone represents 5 cents. A nickel is 5 cents, so it makes 1 tone.
A nickel makes one tone.
OK. So, using that information, how many tones would a dime make?
A dime makes one tone.
Why does a dime make one tone?
A dime makes one tone because each tone represents 5 cents. A dime is 10 cents, so it makes 1 tone.
Check your math on that one.
A dime makes one tone because each tone represents 5 cents. A dime is 10 cents, so it makes 2 tones.
Yes, now you understand.
If a payphone generates 5 tones when a quarter is placed in it, how many cents does each tone represent?

Knowing this information about how the payphone communicates with the company by making tones, how could a person use this information to make free phone calls?
A person could use this information to make free phone calls by placing a piece of paper or some other object in the payphone instead of money. The payphone would then generate tones, just as if money had been placed in it, and the company would think a call was being made when no money was actually being spent.
That would not work, it would know the difference between the paper and the coin. Think of another way the tones could be used to get free calls.

No, this is not possible. Nothing can replace the coin. But, there is a way to use the information about the fact that the phone sends tones to the company to represent what coin is placed in it. How can this information be used without putting anything into the phone?
One way to use this information without putting anything in the phone is by making a tone generator. This can be done by hooking up wires to a power source and playing with the frequencies until the correct tones are generated. Then, when these tones are played into the payphone, it will think money has been placed in it even though no money was actually used.
Yes
Another way to use the information without putting anything in the phone is by using a device called an acoustic coupler. This device converts sound into electrical signals. So, if you have the correct tones, you can play them into this device and it will generate the same signal that would be sent if money were actually placed in the payphone.
How could this be done with a tape recorder instead of a tone generator?
One way to use this information with a tape recorder is by recording the tones that are made when money is actually placed in the payphone. Then, you can play back these recorded tones into the phone and it will think money was placed in it even though no money was used.
Correct
