The day that began touch-tone dialing

Headline is of today's print edition. Post would not be accepted with the digital edition headline.

Yeah, I know it is insensitive. But the beginning of this week is the 50th anniversary of another event that changed America even more than the one at the end of the week.

And we got it first here in SW Pennsylvania, the place where other significant inventions debuted, including penicillin, the Ferris Wheel, the Big Mac and the banana split.

It was cumbersome, but you could actually dial back then without the dial....just push the or holder up and down fast enough and it would dial the ‘number’.....

[foreverfree]

bump (or is it beep?)

[RayChuang88]

I wonder does rotary dial phones still work on land lines?

[Vendome]

Or use a demon dialer.

[Vendome]

Yes.

[Calvin Locke]

Did you know that area codes were originally laid out by population density?

This was to minimize the pulse dialing overhead that would tie up the long distance lines without providing revenue.

Hence, NYC was 5 clicks, LA/Chicago 6 clicks, and Hawaii/Alaska 26 clicks.

I miss the rotary dialer phone in the office. I used to dial phone numbers using my pencil (with the eraser tip). The pencil just sort of hooked into those rotary holes perfectly. Dialing numbers that way yielded a satisfactory "mechanical" feedback as the dial whirred back to home position after each number.

Also, I remember a trick where if you inverted the first three digits of your own phone number and then dialed the next four, you would make your own phone ring. I don't think that works anymore but in the 1970s, it did work and I would fake getting phone calls. Can't remember what value that provided but as a kid, it seemed pretty cool.

Prank phone calls were big in the 1970s. That was before people at home had caller ID so you could have all kinds of fun without getting caught.

The first patent for a rotary dial was filed by Almon Brown Strowger on December 21, 1891, which was awarded to him on November 29, 1892 as U.S. Patent 486,909.[1][2] The early forms of a rotary dial used lugs on a finger plate instead of holes and the pulse train was generated without the control of spring action or a governor on the forward movement of the wheel, which proved to be difficult to operate correctly. The commonly known appearance of the rotary dial with finger holes was first introduced in 1904 but did not enter service in the Bell System in the United States until 1919,[citation needed] when AT&T abandoned its determined reliance on manual exchanges, and embraced automatic switching.

From the 1960s onward, the rotary dial was gradually supplanted by dual-tone multi-frequency push-button dialing, first introduced to the public at the 1962 World’s Fair (Seattle, WA) under the trade name Touch-Tone®. Touch-tone technology primarily used a keypad in form of a rectangular array of push-buttons for dialing.

From as early as 1836 onward, various suggestions and inventions of dials for sending telegraph signals were reported. After the first commercial telephone exchange was installed in 1878, the need for an automated, user-controlled method of directing a telephone call became apparent. Addressing the technical shortcomings, Almon Brown Strowger inventing a telephone dial in 1891.[3] Before 1891, numerous competing inventions, and 26 patents for dials, push-buttons, and similar mechanisms, specified methods of signalling a destination telephone station that a subscriber wanted to call. Most inventions involved costly, intricate mechanisms and required the user to perform complex manipulations.

The first commercial installation of a telephone dial accompanied the first commercial installation of a 99-line automatic telephone exchange in La Porte, Indiana in 1892, which was based on the 1891 Strowger designs. The original dials required complex operational sequences and development continued during the 1890s and early 1900s in conjunctions with improvements in switching technology.

In the 1950s, plastic materials were introduced in dial construction, replacing metal which was heavier and subject to higher wear.

Despite their lack of modern features, rotary phones occasionally find special uses. For instance, the anti-drug Fairlawn Coalition of the Anacostia section of Washington, D.C. persuaded the phone company to reinstall rotary-dial pay phones in the 1980s to discourage loitering by drug purchasers, since the dials could not be used to call dealers’ pagers.[4] They are also retained for authenticity in historic properties such as the U.S. Route 66 Blue Swallow Motel which date from an era of named exchanges and pulse dialling.

Yes, you can use them on today’s phone system! Legacy system.

Here’s the batphone being dialed to Commissioner Gordon!

In the 1960s, our phone in rural Iowa was on a party line. There was a crank handle on the phone to ring the attention of the operator.

So you’re the one who wore the numbers off the face.

Many people may know that the DTMF tones (the “beeps” you hear when you punch the buttons) are copyrighted by the phone company. What you may not know is that the dial tone, the busy signal, and the off-hook alarm are also copyrighted.

And on an old rotary phone, you could dial a number subtractively. If you wanted to dial a 4 for instance, you could put your finger in the 7 hole and move it to 3. Or 9 to 5. Etc.. The system worked by counting the number of pulses as the dialing wheel passed a sensor, so it didn’t care how those pulses were sent. Which also enabled a user to simply click the hangup buttons a specific number of times in rapid sequence to effect the dialing of a number.

[pax_et_bonum]

Yes, but WE remember using smoke signals and carrier pigeons and primordial conch shells.

[PowderMonkey]

I really don't miss the rotary dial phone myself. The office environment in those days was simply awful. The constant jangling of telephone bells on everyone’s desk alone was enough to drive you crazy. Add to that the sound of hundreds of manual typewriters throughout the building, and the pall of cigarette smoke that hung down three feet from the ceiling, and the blaring PA systems, and the smell of mimeograph copies, and smudgy carbon paper…nope I don't miss the old days at all.

[GingisK]

Few people notice that they are still being charged for the “extra service” of touch tone dialing. You got to love AT&T.

[equaviator]

Once in a while you’ll hear some recording or a person trying to route a call say “please dial one” or “please dial the operator”.

[deweyfrank]

Yep. It was actually cheaper to provide Touch Tone dialing then it was Rotary dialing, but they continued to charge extra for it.
