And back again: England, 1988 In 1988, collectors recognized phone cards as an interesting collectors' item and began collecting them much like they collected sports cards. The advent of phone card collection spurred Dr. Steve Hiscocks to create "The Collectors' Book of Telephone Cards," the very first catalogue of telephone cards. The publication covered 61 countries, or all those producing international phone cards at the time, with the exception of Singapore and Japan. The book was an incredible 108 pages! In the next few paragraphs, we'll discuss the science behind telephone calls. How it all works Prepaid long distance phone service begins with you. When you pick up your handset at the home or office, the device turns your voice into an analog signal, or electrical impulse, which travels along the wire. Digital signals are also available now, though analog is still widely used. The signal travels through a phone line composed of two copper wires originating in your house, which disappear into a box if you have underground wiring, or are suspended between poles near your house if you have aerial wiring. Near your house, your phone line will join with your neighbors' lines, and all these cables are spliced into a 25- or 50-pair wire. The analog signal travels along the cable, through the neighborhood, until it reaches another, bigger box, which is the junction connecting your neighborhood wires to the main line running past it.
