The regulation was carried over after the telephone system was deregulated in the 1980s but it appears to have faded away since then. Rotary phones persisted.īecause of the slow rollout, regulators required AT&T, the national Ma Bell telephone network, to support both pulse and tone dialing. However, the new system required major upgrades to the telephone infrastructure of network switches and local exchanges, so it took a while before touch-tone phones were common in homes and offices. After the war, when transistors started to see mass adoption in consumer products, electronics could be compressed and robust enough to fit inside a small telephone device.Īt the 1962 World's Fair, AT&T demonstrated the first Touch-Tone interface, ushering a new era of telephone communications. Their first systems involved mechanisms of vibrating reeds to signal across the telephone lines. With what am I communicating on my phone if it's not really your voice? Press 2 for Touch-TonesĪT&T was working on a replacement for rotary dial phones since before World War II. I often wonder what gets lost in translation. The game of telephone is one of idea-hopping from one complex system to the next. Our brain's neurons somehow reassemble into some simulation of a human voice. Sometimes it takes a journey in the depths of the ocean and impossibly emerges from the abyss to begin its metamorphosis through the systems back into electricity and sound. Our transformed voice burrows underground, flies through the air, and bounces off of satellites in space. The real magic begins as the telephone systems route these signals across light beams in fiber optic cables and electric current through copper. The now pale representation of our original idea travels over radio frequencies to cell phone towers. The phone circuitry analyzes and manipulates these bits into a compressed stream. This device creates an analog signal that electronics turn into a digital sequence of 1's and 0's. Ideas travel from our brains along our nervous system to vibrate the vocal cords that push air towards a tiny magnet in our headsets. These systems intermingle fluidly, and it's often unclear where the boundaries begin and end. The telephony system is an incomprehensibly complex amalgam of mechanical and computerized devices spanning multiple decades of vintage. It was the melody that my fingers sang when I wanted to reach out and touch my home. I still remember my first phone number because of the way it sounds. I can still feel the squishy buttons with their phosphorescent backlit glow on that yellow corded phone in my childhood kitchen. I grew up around some rotary phones, like the one at grandma's house, but I'm of the Touch-Tone generation. We now carry supercomputers around in our pockets that we laughingly refer to as "phones." However, we still cling to a bygone era as we stroke the smooth numeric keypads on iPhones and express outdated social norms through our telephony handshakes, "Hello." I started thinking about the nostalgia of phones before the era of blackberries and mobile devices. It was soothing to hear the computers start a conversation with each other. Every time I placed a call through the computer, the modem's speaker would emit a series of touch-tones, squeaks, and static that I came to recognize as my successful passing into the world of BBS's and ultimately the internet. Of course, I certainly talked to friends for hours on the phone, but I also spent just as many hours connecting with other computers over modems. It was a sign of luxury (or parental capitulation) when the teenager got a separate phone line. ![]() She was bubbling as she recalled, "they lit up when someone was calling!" She told me about her party line conversations with friends while they chatted about boys and homework on those ubiquitous 1980's clear phones. ![]() Our chat turned to phone calls on landlines and what it was like when entire households shared the same phone number and the clicks of someone picking up the extension in the other room, "MOM! Get off the phone!" ![]() I had a meeting with a colleague a few days ago, and she requested that instead of a video chat over Zoom, we should pick up the phone and have an old-fashioned audio-only conversation like human beings.
