03:13
This film explores the story of the Enfield telephone exchange and the role of female operators in the development of telephone networks. The Enfield exchange was one of the last to be converted from manual to automatic switching. After closure, the Science Museum preserved a section of the switchboard which is now on display in the new Information Age gallery along with stories of the women who worked on the exchange. Information Age tells the story of how our lives have been transformed by information and communication technologies over the last 200 years.

Automatic telephone exchange - operating
 
01:11
A step-by-step automatic telephone exchange brought into operation in 1921 at a post office in Ljubljana, which was the first automatic exchange in the then Kingdom of Serbs, Croats and Slovenes (later Yugoslavia). Originally it connected 500 users, but the facilities were later upgraded. Before being donated to the Museum of Post & Telecommunications in 1981, it had a total of 2000 subscribers. Two automatic telephones are connected to the exchange; the first is a Siemens & Halske and the other Telefongyar R. T. Budapest.

AT&T Archives: The Step-By-Step Switch
 
08:26
See more from the AT&T Archives at http://techchannel.att.com/archives The purpose of this film was to show employees, back in 1951, how calls were automatically switched through an SxS office. This film gives a general appreciation of the importance, complexity, and cost of switching equipment in an average 1950s telephone office. The path of a call is illustrated as it runs through a demonstration unit. "Careful adherance to Bell System maintenance practices" is stressed. While this is only part I, Part II eventually showed the equipment in various types of use, and Part II showed the internal circuit operations. Switchers today are digital and look drastically different. These systems at this time were still not even transistorized, so this film shows a system that's not only years back in time, but many generations back in terms of technology.

Telephone Exchange in a Box (Stage Telephone Ringer)
 
11:50
Telephone Intercom System (Stage Telephone Ringer). Dubbed "Exchange in a Box" . Available for sale in the UK here: https://oldvintagetelephones.co.uk/Telephone-Intercom-stage-telephone-ringer Behaves intuitively, exactly like making calls to and from standard UK land line telephones, so no training or skills required and no embarrassing moments like the telephone continuing to ring when it has been picked up. Much better than any simple electronic "telephone ring generator". Please note that because this solution is specifically designed for UK land line telephones (the UK have a 3 wire, rather than a 2 wire internal wiring telephone system) this solution will not work without adaption in the US. Hence this "Exchange in a Box" is currently only available for sale in the UK.

Impulswiederholer - Telephone Exchange
 
01:40
Eines der Bauteile das wirklich faszinierend ist. Der Impulswiederholer ist ein elektromechanischer Ziffernspeicher. Dieses Teil speichert die Wahlinformationen und gibt sie in der Reihenfolge wie sie eingespeichert worden wieder aus. Dabei ist der Ausspeichervorgang zeitlich unabhängig vom Einspeichervorgang. Außer der Zwischenwahlpause sind die ausgegebenen Impulse unabhängig von den Eingangsimpulsen. Der Impulswiederholer kann daher auch verzerrte Impulse wieder in einer sehr sauberen Form ausgeben. Der Speichervorgang läuft zyklisch ab, das heißt wenn die Auspeicherung vor dem Vollaufen erfolgt, hat der Impulswiederholer ein unbegrenztes Fassungsvermögen. Deshalb eignet sich dieser Teil sehr gut als Durchlaufspeicher. Das erlaubt im Verbindungsaufbau der nachfolgenden Schaltungen eine große Freizügigkeit In Zusammenhang mit einer einfachen Relais Schaltung arbeit der Impulswiederholer mit drei voneinander unabhängigen Magnetspulen. Dem Einspeichermagnet, Markierungsmagnet und dem Ausspeichermagnet. Das mechanische Speicherelement vom Impulswiederholer ist eine Lammelenscheibe mit 72 federnden Lamellen die drehbar in einem Laufring angeordnet ist. Der Einspeichermagnet dreht die Scheibe bei jedem eintreffenden Impuls um einen Schritt weiter. Der Markiermagnet drückt die Lamellen bei angezogenem Magneten auf die eine Seite des Ringes und bei abgefallenem Magneten auf die andere Seite des Ringes. Der Markiermagnet wird erst nach dem ersten Impuls einer Impulsreihe erregt, dadurch wird die erste Lamelle nicht ausgelenkt und bleibt auf der Abtastseite. Diese Markierungen bleiben währende einer vollen Umdrehung der Lamellenscheibe erhalten und kennzeichnen dadurch das Ende einer zuvor gespeicherten Impulsreihe. Bis zum Beginn der Ausspeicherung können 64 Impulse gespeichert werden. Auf der anderen Seite (Abtastseite) befindet sich der Abtastarm. Dieser Arm bewegt sich beim Einspeichern mit der Lammelenscheibe mit. Beim Auspeichern gleitet der Abtastarm entgegen der Drehbewegung der Lammelenscheibe über den Lammelenauflagering hinweg und tastet dadurch jeden Lammelenschritt ab, bis er am Ende der Impulsreihe markierten eingespeicherten Lamelle angehalten wird. Nach einer kleinen Pause zählt er die weitere eingespeicherte Information ab. Er wird am Ende der zuletzt eingespeicherten Wahlinformation endgültig stillgesetzt in der Nullstellung des Abtastarmes.

The Life of a Telephone Operator in 1969 (with special introduction) - AT&T Archives
 
17:01
See more from the AT&T Archives at http://techchannel.att.com/archives Bonus Edition Introduction by George Kupczak of the AT&T Archives and History Center. A non-linear documentary about operators - male and female, but mostly female - at their work, and describing their work and the type of customers they encounter. A fascinating inside look at the skills needed by operators in dealing with the public. Shot in the style of a Maysles- or Weisman-type documentary. There are clips from a 1913 D.W. Griffith silent film, Telephone Girl and the Lady, at the beginning and end. "The operator's job, despite tensions and aggravations, is one which consists primarily of human contact and as such, carries rich rewards." Cox went on to direct television in Hollywood and also documentaries for PBS. She now lives in Kentucky and still makes documentaries. Cox also made "All in a Day's Work" for AT&T. Directed by Nell Cox Song "Operator" by the New York Rock & Roll Ensemble was originally released as a 45rpm record. Footage courtesy of AT&T Archives and History Center, Warren, NJ

Telephone exchange for vintage phones.
 
04:52
Demonstration of a 5 line telephone exchange now available. Works independent of the telephone service, this is a self contained telephone exchange for vintage phones. It works like a kind of intercom. You can wire up the phones in different rooms and dial the number for a particular phone and it will ring. It generates the old style buzzing dial tone when you pick up the receiver. Please note this is for rotary phones only and will only work with newer phones if they have a pulse dial settings. DO NOT try and connect to an outside telephone service like at&t etc as this will damage the exchange and is probably illegal!

The guys taking the wiring were not pleasant, but with all these environments you just hope that people are there to 'do their thing' and leave. The fact is, even I do not enjoy places like this. I've seen stories where other explorers have gone on a rampage smashing windows and starting fires, then they leg it when the police arrive leaving people that were only taking pictures to take the blame. Other stories tell of people that have been trapped inside a building when the entrance point was closed or sealed by others on purpose when they left, because they thought it was clever... Yes, explorers trapping other explorers in a building. There was an old hotel where they knocked out the ground and first floors to try and stop people getting in the tower block. People still entered, but one guy FELL TO HIS DEATH trying to get out afterwards by using a rope which presumably came detached. This wasn't that long ago. Some of the external walkways featured in this building I would never walk on, injury or even death is a real risk here and you really have to watch what you're walking towards. I've seen lots of instances where the floor would have given way if stepped on, due to years of decay. There is a car park in Bracknell with a trap-door in the motor room that's covered by about 2cm of pigeon poo, invisible, unless you noticed it when climbing up a separate ladder (which was not attached at the top!). No doubt about it, a fall of about 10 metres onto concrete - you're dead. With all this in mind, don't copy - STAY OUT OF ABANDONED BUILDINGS. When things go wrong, they can go very wrong. ###### I'm trying to clear some room on my HDD to make way for some really epic videos! Just finishing off a couple of videos like this one.

The site of No.22 has an interesting history. It has been the home of a singer and musician, State Councillor, Governor, Chief of Police and a telephone exchange. The building was reconstructed several times, to reflect the needs of the various owners. The Telephone Exchange at Marine 22, was launched in 1905 and operated until 1950. Today, the building still houses its "telephone" heritage. Where once there were huge cabinets with countless bundles of wires, rows of telephone operators in long rows, now houses offices of "Rostelecom", the Internet, Cable TV and Telephone Service Co.

AT&T Archives: Switchboards, Old and New (Bonus Edition)
 
13:21
See more from the AT&T Archives at http://techchannel.att.com/archives Introduction by George Kupczak of the AT&T Archives and History Center Switchboards, Old and New traces the development of voice switching methods from the first system that utilized the wires of a burglar alarm unit in Boston in 1877, to the "latest type" of switching in central offices, circa 1932. Along the way, we get the evolution of the Operator as well. Originally teenage boys were hired as operators, but it was quickly noted that they were not ideal due to being rambunctious and prone to pranks. Emma and her sister Stella Nutt were the first female operators, hired in 1878. They started a tradition that continued to the 1970s, when equal hiring practices made it possible for men to become operators as well, again. Switchboards started to be replaced by TSPS (Traffic Service Position System), starting in 1969. Voicemail trees, also called Interactive Voice Response, also replaced operators. In 2000, there were fewer than 300,000 operators working in the U.S., most at the switchboards of large companies or hotels. That number continues to drop by the thousands every year.

► THE EXPLORE: Not a huge explore, but still a fun one. We had a bit of a laugh taking some pictures getting some cool cinematics and generally messing about. Hope you enjoy! ► SITE HISTORY: A telephone exchange is a telecommunications system used in the public switched telephone network or in large enterprises. An exchange consists of electronic components and in older systems also human operators that interconnect (switch) telephone subscriber lines or virtual circuits of digital systems to establish telephone calls between subscribers.

from 1980's "Live Without A Net", should be the studio version, but you can thank the Universal Music Group for that...
