ALBUQUERQUE, New Mexico – In front of a row of rotary phones, a volunteer at the New Mexico Telephone Museum told me that most children don’t know how to use them. Most of them had never seen a rotary phone before.

I’m familiar with rotary phones since I was a kid, but there are old phones here that I’ve seen in old movies.

This museum is the place to go to see how we got to modern smartphones from Alexander Graham Bell’s conical devices that in 1876 brought the first telephone sentence: “Mr. Watson, come here. Want when I see you.” Bell’s words to his assistant were said to be the result of acid spilling on his hand. All these years later, we still use our phones to call for help.

The New Mexico Telephone Museum is a little place that most people who live in Albuquerque have never heard of. It is filled with four floors of telephones, keyboards, maintenance equipment, and scale models of Telstar satellites. Be still, my genius heart.

I love the steampunk aesthetic of Magneto’s payphones from the late 1800s, with their dark wood bodies, exposed bezels, and old-school trunks.

I think this is one of the earliest examples of a handheld headset. It is an ear and chest transmitter worn by panel operators. Can I get one of these to use on my cell phone? That’s really cool.

As much as I love the sleek and stylish phones of today, I was also disappointed by the brushed wood and brushed metal designs of the old phones.

The Western Electric Model 500 series telephone was the standard domestic office telephone manufactured by Bell Systems in North America from 1950 to 1984. Bell Filter System. Millions of Series 500 phone models were produced and found in most North American homes. Many are still used today because of their durability and wide availability. Its modular construction makes it easier to build and repair than previous types, and facilitates multiple versions with additional features.

Touch tone service was introduced to residential customers in 1963 with the Model 1500 telephone, which had a t-digit dial pad. The Model 2500 telephone, introduced in 1968, added the * and # keys, and is still produced by many manufacturers.

The Western Electric Type 500 telephone replaced the Type 300, which had been in production since 1936. Designed by the company of industrial designer Hry Dreyfuss, the Model 500 was the result of years of research and testing in collaboration with Bell Laboratories. and Western Electric. Development began in 1946 with initial sketches by Bell engineer and Dreyfuss associate Robert Hose, leading to pre-production units in 1948 and field trials in 1949 with 4,000 telephones per year in 1949. Announced by AT&T publicized the new phone in 1949 and announced the availability of the first Approxima. 23,000 kits in the second quarter of 1950 for Bell System operating companies on May 1, 1950.

Production for the third and fourth quarters is estimated at 49,000 and 93,000, respectively. Including 20,000 units of the Special Purpose Group (501B), approximately 183,000 units have been produced since the first year of d production.

In the following years, due to the better electrical and audio efficiency of the new model, the regular transfer of 25 million Type 300 telephones was started.

This efficiency allows the new model to be used in long rural loops, which previously required special sets with local batteries to operate the transmitter, and not only in short urban loops, because it has self-directed control. It also allows the use of wires with thin loops and thus saves the cost of building the network.

Replacing 300 series phones with 500 series sets created large 300 part inventories that did not reach their intended service life. The increased demand for new telephone service in the 1950s put pressure on manufacturing facilities, so the Bell system reused these old components to produce 302 telephones with modern houses similar to 500 models. , but from the point of view of electricity , it is good for phones. 302 old people. This program began in 1955, and the modified set was called the Model 5302 telephone. It was made in the repair workshops of each Bell Operating Company, not on the assembly lines of Western Electric factories, until the mid-1960s.

From the field tests of 1949 to 1953, only the black parts of the Type 500 telephones were produced. Color telephones were introduced in several stages from 1954 to 1957, as production capacity improved and material selection processes were perfected.

In the 1960s, after the introduction of tactile tone service in November 1963 in various parts of the telephone network, the basic chassis of the Type 500 was replaced by a push-button keyboard, with a new housing and a new face, and the Model. 1500 for 10 is done. The button version and in 1968 the 2500 model had 12 keys.

The 1970s brought a transition to modular connector technology, replacing stranded wires with wires terminated with 4P4C connectors for telephone and 6P4C plugs for line cable.

Like most telephones in the United States, Series 500 telephones are owned by local Bell Operations and leased to customers on a monthly basis. Phone style and color options are limited. AT&T, the major owner of the operating companies and Western Electric, imposes strict policies against the purchase and use of other manufacturers’ phones on its network to ensure the technical integrity of its network. and avoid competition. Most telephones made by Western Electric, starting around 1968, had this disclaimer built into their housings: “BELL SYSTEMS EQUIPMENT – NOT APPROVED.” The phone is sometimes also marked with a sticker or ink stamp that shows the name of the carrier that owns the phone. After consumers started buying phones from other manufacturers,

After legal developments failed to challenge AT&T’s ban on third-party equipment, AT&T changed its policy for its Design Line line of phones by selling the phone’s housing to customers while retained ownership of the electrical components, so customers still had to pay AT&T. monthly rent.

In 1983, after the court ordered the recovery of the Bell system, AT&T began selling public telephones through the newly created Bell US division. Many customers are offered the option to purchase leased phones that are in their service. AT&T closed its US consumer phone manufacturing plants in 1986 and moved production overseas to Singapore, China, and Thailand, and expanded to Mexico in 1990; This allows them to make phones at a lower cost.

In 1975, the design of the 500 was essentially unchanged, but it used the revised standard dial and strings and was available in a variety of new colors.

The Western Electric 500 improves on many design features of previous phones. While the 302 switch and hook are directly attached to the metal or plastic case, all the operating parts of the 500 phone are attached to the base plate, and the housing has only two screws to activate the hook switch where the phone mounted. from the cradle. This way, the phone can be easily tested and serviced without a case. This design improves productivity and ease of service. The previous 302 was equipped with an impressively projected dial that displayed numbers and letters within the grooves of the rotating thumb wheel. Years of use cause the letters and numbers to fade, just like porcelain tile. The 500 design improved on this by molding the letters into plastic using a dual injection molding process. This design was carried over to the 1500 and 2500 series phones and used sharp-tone keys to eliminate wear. The numbers and letters of the 500 have been changed to make it work
