Several transmission systems have been prevalent in the digital world, since it started to boom, but even before this great digital expansion these systems were in use and ever important. Prior to everyone being addicted and living on their smartphones, there was a more simple time, a time in which you would have to call an operator and they personally would have to change the circuit for you.
