Phreaking 101
The telephone communications network, as it existed in the late 1950’s until the early 1990’s, used a system of sonic frequency tones to perform functions within the network. The exploration of the intricacies of this system would lay the foundation for phone phreaking. For example, when a caller hung up a phone, a tone would be sent to the carrier network to indicate that the call had ended. Other tones could be strung together to perform actions such as making free long distance calls, makeshift conference calls, relay systems, and dialing into unlisted or secret receivers. Famed phone phreaker John Draper said “The fact that the phone company allowed the system to be set up that way, was unbelievable. I was flabbergasted”.
