The Making of Information Age: Enfield Telephone Exchange
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.

AT&T Archives: The Step-By-Step Switch
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.

Introduction to Telephone Systems
Follow Eli on the Vlog Channel: https://www.youtube.com/user/EliComputerGuyLive Info Level: Beginner Presenter: Eli the Computer Guy Date Created: August 2, 2010 Length of Class: 54 Minutes Tracks Telephone Systems Prerequisites None Purpose of Class This class introduces students to the basic components of telephone systems. Topics Covered Public Switched Telephone Network Central Offices Trunk Lines PBX and Voicemail Systems PBX Stations Voicemail Subcribers Class Notes Introduction Telephone systems are not complicated if you understand how they work. A Word on VoIP VoIP is not a telephone system PSTN PSTN -- Public Switched Telephone Network is like the Internet, but for telephone communication NADP -- North American Dialing Plan -- Is the system for routing telephone calls. Central Office -- All telephone lines connect to a local central office Trunk Lines Every Trunk Line has a telephone number A Trunk Line allows for 1 incoming or outgoing call. You can have far more telephones in a building then you have trunk lines. Incoming Trunk lines are setup in Hunt Groups. If the main phone number is busy the call is automatically forwarded to the next number in the Hunt Group Incoming Hunt Groups are setup by your local telephone company. Outgoing calls can be routed to use selected trunk lines. This in configured in your PBX. PBX and Voicemail The PBX routes telephone calls The Voicemail system provides all audio messaging. (Voicemail boxes, Message Boards, and Auto Attendant Messages) Stations All devices that connect to the PBX are "Stations". This includes telephones, call boxes, intercom systems, etc. There are 2 types of stations; Analogue and Digital. Analogue and Digital stations have to be connected to appropriate ports on the PBX. An analogue phone cannot connect to a digital port and vice versa. Almost all fax machines and phones you buy at retail stores are analogue. If your new fax machine does not work it may be because it's plugged into a digital line. Subscribers Subscribers are users of the Voicemail system. Subscribers do not have to have stations Voicemail ports are the number of connections to the Voicemail system at any one time. This includes not just people retrieving their voicemail, but also incoming calls that connect to Auto Attendant messages. Final Thoughts Be careful before you touch! Most older telephone and voicemail systems were administered using a phone keypad, NOT and computer interface. If you mess something up it can be very difficult to rebuild a deleted Auto Attendant or such. Resources North American Numbering Plan PSTN -- Wikipedia

Automatic telephone exchange - operating
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.

The Last Towns to Use Operators to Connect Calls - AT&T Archives
Bonus Edition introduction by George Kupczak of the AT&T Archives and History Center A film about the last few offices in the United States that, in the 1970s, had yet to convert to the dial system: Catalina Island, California Catalina Island has been an important little corner of the AT&T world. In fact, the link between Catalina and Los Angeles was the very first in the Bell System to be wireless. The island was linked to the mainland via a radiotelephony system all the way back in 1920. For having such a significant telephone technology first, it's ironic that this film chronicles the city's telephone technology "last". Virginia City, Nevada In the film, an operator — in fact, the only operator — who had been working in Virginia City since 1949 is interviewed about the prospective cutover (a cutover is a switch from one type of telephony system to another). She talks about the fact that they will have automation, and more than one operator. Virginia City hasn't grown much since then, however. The city proper still has a population of only around 850 people (2010 census). St. Ignace, Michigan As this city still used 1940s switchboards, the incipient electronic switching system was to completely change telephone operation in this sleepy summer tourist town. But towns with no dial service also had customers who couldn't get then-modern features like call waiting on their phones. Footage courtesy of AT&T Archives and History Center, Warren, NJ

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

The Traveling Telephone Switching Machine - AT&T Archives
See more from the AT&T Archives at http://techchannel.att.com/archives The #5A Crossbar switcher, built by Western Electric at the Columbus Works, was a telephone switching machine that could handle either around 1000 lines, or up to 2000 with an extension upgrade. This made it ideal for smaller towns and communities, new large subdivisions, and larger companies. The crossbar switch itself took up 10 by 42 feet, and weighed 25 tons. The machine was pre-assembled in Ohio, and then trucked to its final installation site. This film shows the assembly and transportation, and further details about the crossbar switch's "plug and play" type of capabilities. The Columbus Works were one of the Bell System's later plants, built specifically for switching equipment manufacture, and opened in the late 1950s. It eventually manufactured not just the crossbar switch but also the 4ESS digital switch. The last major manufacturing effort AT&T ran at the plant was its Airloop, which was a wireless system announced in 1995 that was a potential replacement for crossbar-type switching systems in hard-to-reach areas. It could bring quantities of new lines to the network wirelessly, without having to build in new trunk lines to a site. At its peak, the Columbus Works employed around 12,000 workers, including 1,000 Bell Labs employees alone. In 1996 it became part of Lucent Technologies, which sold the plant in 2003. Today, the office building on the site is still occupied, but much of the manufacturing plant is empty.

Speedy Cutover Service, SXS switching cutover to ESS filmed live at Glendale CA central office, 1984
A brief but surprisingly exciting 1984 video showing the preparation and live, real-time cutover from Step By Step switching system (SXS) to a new electronic switching system (ESS) in Glendale, California. Western Electric offered the Speedy Cutover Service to switching offices throughout the Bell System. Western Electric installers would visit a facility and prepare it, installing the new equipment inside the facility. They would identify and mark the existing cables that would need to be cut, then prepare employees for the cutover to the new ESS system. Previously a cutover from step-by-step (or from crossbar service) to ESS would take many frantic minutes, upwards of an hour, during which time active telephone service would be lost mid-call. With the speedy cutover service – 51 installers simultaneously cutting 927 cables as fast as possible, all on cue – the interrupted service could be brought down to well under a single minute. The climax here is unquestionably the moment of truth, the cutting of the cables, which is shown in real time. After making sure no emergency calls are underway, and with a shout of "Let's cut it!" the race is on, with three camera set-ups and a disco score capturing and preserving the moment of truth.

Telephone exchange for vintage phones.
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!

AT&T Archives: Switchboards, Old and New (Bonus Edition)
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.

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.

PBX Private Branch Exchange Telephone Systems: "Invisible Diplomats" (1965) AT&T; Audrey Meadows
Please considering supporting the channel through my patreon link to help continue the consistent uploads. https://www.patreon.com/oldmoviesreborn Thanks. AT&T high-end business marketing film for PBX (Private Branch eXchange) switchboards. The film stars Audrey Meadows & Ruta Lee, the cinematographer was Hal Mohr (A Midsummer Night's Dream, The Phantom of the Opera, Rancho Notorious...). Two different kinds are shown: Audrey Meadows' PBX is a more traditional cord switchboard. The operator answers and connects calls by plugging cords into jacks. Ruta Lee's PBX is the latest (in 1965) cordless switchboard. Calls are processed by pressing a sequence of buttons, instead of using cords and jacks. http://en.wikipedia.org/wiki/Business_telephone_system#Private_branch_exchange A private branch exchange (PBX) is a telephone exchange or switching system that serves a private organization and performs concentration of central office lines or trunks and provides intercommunication between a large number of telephone stations in the organization. The central office lines provide connections to the public switched telephone network and the concentration aspect of a PBX permits the shared use of these lines between all stations in the organization. The intercommunication aspect allows two or more stations to establish telephone or conferencing calls between them without using the central office equipment. Each PBX-connected station, such as a telephone set, a fax machine, or a computer modem, is often referred to as an extension and has a designated extension telephone number that may or may not be mapped automatically to the numbering plan of the central office and the telephone number block allocated to the PBX. Initially, the primary advantage of a PBX was the cost savings for internal phone calls: handling the circuit switching locally reduced charges for telephone service via the central office lines. As PBX systems gained popularity, they were equipped with services that were not available in the public network, such as hunt groups, call forwarding, and extension dialing. In the 1960s a simulated PBX known as Centrex provided similar features from the central telephone exchange. A PBX is differentiated from a key telephone system (KTS) in that users of a key system manually select their own outgoing lines on special telephone sets that control buttons for this purpose, while PBXs select the outgoing line automatically or, formerly, by an operator. The telephone sets connected to a PBX do not normally have special keys for central office line control, but it is not uncommon for key systems to be connected to a PBX to extend its services. A PBX, in contrast to a key system, employs an organizational numbering plan for its stations. In addition, a dial plan determines whether additional digit sequences must be prefixed when dialing to obtain access to a central office trunk. Modern number analysis systems permit users to dial internal and external telephone numbers without special codes to distinguish the intended destination. History The term PBX was first applied when switchboard operators managed company switchboards manually using cord circuits. As automated electromechanical switches and later electronic switching systems gradually replaced the manual systems, the terms private automatic branch exchange (PABX) and private manual branch exchange (PMBX) were used to differentiate them. Solid state digital systems were sometimes referred to as electronic private automatic branch exchanges (EPABX). Today, the term PBX is by far the most widely recognized. The acronym is now applied to all types of complex, in-house telephony switching systems. Two significant developments during the 1990s led to new types of PBX systems. One was the massive growth of data networks and increased public understanding of packet switching. Companies needed packet switched networks for data, so using them for telephone calls was tempting, and the availability of the Internet as a global delivery system made packet switched communications even more attractive. These factors led to the development of the voice over IP PBX, or IP-PBX. The other trend was the idea of focusing on core competence. PBX services had always been hard to arrange for smaller companies, and many companies realized that handling their own telephony was not their core competence. These considerations gave rise to the concept of the hosted PBX...

Exclusive: Inside Verizon's 3G and 4G Network | Pocketnow
On the heels of the one-year anniversary of its 4G LTE service rollout, Verizon Wireless has granted Pocketnow exclusive access to one of their switches in southeastern Pennsylvania. The switch (or Mobile Telephone Switching Office -- MTSO) is a hub of Verizon's network in the Philadelphia tri-state area: it's what connects the towers in the region and processes all voice and data calls. The switch, which is a building filled with miles of fiber optic cable, a battery backup system and a generator system, dozens of servers, and a control room that monitors precise data as it pertains to the performance and stability of the system, is a marvel of engineering and technology. We also get to witness Verizon's obsession with reliability of their network. Each and every component is redundant within the switch so that if there are any equipment failures or even a natural disaster that disrupts power to the entire facility, Verizon customers are likely to still have service. We also learn a lot about the difference between Verizon's 3G and 4G network, the latter of which now reaches 200 million people in 190 markets across the U.S., including much of the Philadelphia region. During multiple Q&A session, we learn about the capabilities of Verizon's 4G LTE network, which is only going to increase with further network upgrades. Thank you to the folks at Verizon Wireless for letting us take a tour of the infrastructure that is responsible for making their network operate.
