Why is it the same whether it is 1 mile or 10000 miles?

When you talk into your phone, the voice is converted into electrical signals. Electicity travels at the speed of light. This is delivered to your central office where it is convereted into a digital signal. Your central office should be withing 5 miles from you. So, barring any problems with the wire, the telephone switch will receive a full powered signal. After, the conversion to digital, the signal is sent through the network where it goes through several repeaters and amplifiers to insure the transfer is effective. Then when it reaches your distant ends general area, it get converted back to electical signal and sent to the other phone. Again, the distance from the phone to the phone switch will most likely be within 5 miles. Therefore very little loss.

Think of it like the internet as a whole. You can pretty much view any webpage within milliseconds from all over the world. Well with a phone, your voice is converted into binary code (code used by computers to communicate) at some point along the way. With a cell phone, your voice is instantly converted to binary code and with a landline, once your voice reaches the CO (Central telephone Office).
Once digitalized, your signal is sent to wherever in the world you are trying to call. Your signal may travel accross the Atlantic under the ocean or through space with satellites.
This is why many fear the digital world because we have trapped ourselves with technology and if something simple fails, we may lose all communications in an instant.
Hope this helps!

IT has to do with PCM....Pulse Code Modulation.
Your voice is an sinus type of wave and its been converted to electrical impulses ..which in turn are converted to a digital signal by PCM technology.... and on the other end it will be converted back to your voices wave,,,all been regulated by one clock...
and here is where the main secret lies... in the Clock ..that is common on both sides...and the whole worlds clock are synchronized with each other for this type of modulation and demodulation,...
Its a long process, but in the end.... you are talking to your friends in New Zeeland and they hear you as you do sound.

this is NOT true for calls between alaska and the lower 48... at least in 1994/5 when i visited... there was a delay in the conversation.. i was told it was because of the satellite link that the phone company used... hopefully thats resolved now..

Well, sound travels pretty fast. Actually, you'll get more of a delay the farther you are. If you notice carefully, sometimes you'll hear a delay in your conversation if you're talking to someone really far away........
