The Beamish Automatic Telecom
 
04:29
Jonathan Kindleysides, Keeper of Transport and Allan Monkhouse, museum volunteer, introduce us to the Beamish Automatic Telecoms system. The museum has had its own Strowger exchange since 1985 when GEC Plessey, Hartlepool, donated a 100 line Siemens type 222. This exchange operated phones around the Tramway and tram depot. However, it proved to be hard to maintain and not very reliable. In 1992 BT offered the museum a 100 line exchange from Embleton, on the Northumberland Coast. It was decided to abandon the Siemens exchange in favour of the 100 line UAX 13 rural exchange, a workhorse of the GPO. This was installed with help from BT and has spent the last 21 years operating the internal tramway and depot telephones. However, up until recently, only a handful of the possible 100 lines have been used. Over the past few years members of the Tramway Group and volunteers made up of ex-BT engineers have expanded the network across the museum. Work has involved the erection of traditional telegraph poles and wires around the site, and the fitting of period looking handsets and hardware into museum exhibits - reducing the amount of modern technology being used to communicate between teams. The main exchange unit, situated within the Tram shed, is a hive of activity. It is hoped that an exchange building which visitors can access will be constructed within the museum as part of future plans.

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.

Witness the re-commissioning a 46 year old electromechanical private branch exchange. The Ericsson 10+50 Strowger PABX supports 50 extensions and 10 trunk circuits, and a number of surprisingly complex features for a Strowger PABX. I've had this unit in storage for over a decade, this is the first time it's been powered up in probably 3 or 4 years.

This is a 2-digit strowger switch. It counts pulses from a rotary dial telephone (or system) and can accumulate two dialed digits. These were usually combined to allow for longer digit strings. A 7-digit string would require at least 4 of such switches (and a lot of other gear to send the ring signal, the dial tone, the busy tone, etc.) Anyone having knowledge of these (or this stuff in general) please do add your thoughts, especially if I got something wrong.

Speedy Cutover Service, SXS switching cutover to ESS filmed live at Glendale CA central office, 1984
 
04:35
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.

Strowger Switch Demonstration - Frank H. Woods Telephone Pioneer Museum, Lincoln, NE . 7.12.18
 
03:15
Demonstration of the Strowger switch - an electromechanical stepping switch from the former Lincoln Telephone & Telegraph Company telephone exchange system... as seen at the Frank H. Woods Telephone Pioneer Museum on July 12th, 2018. The Strowger switch was the first commercially successful direct-dial system over telephone, via rotary phone. It was an electromechanical system that was very high maintenance, due to frequent friction and its many moving parts... but nevertheless, it connected the world long before touchtone telephone and the internet. These exchanges were first introduced in the late 1890's and were last used all the way into the 1990's. Any Strowger switch today is a rarity. This miniature telephone exchange system was a hands-on exhibit at the Frank H. Woods Telephone Pioneer Museum in Lincoln, Nebraska. The museum was incorporated in 1992 - opened to the public in 1994 and was run by a volunteer group from the former Lincoln Telephone & Telegraph Company, former Alliant Communications, former Alltel Corporation & current Windstream employees. The museum was also seen in the movie "Yes Man" with Jim Carrey. Unfortunately, with area where the museum sits being redeveloped and the museum - mainly relying on donations from the public to keep operating, could not afford to find a new home... nor would the telephone company that once supported it would help (or any other entities within the community). Sadly, it closed at the end of July 2018 - a truly hidden treasure now forever gone. This video was taken less than a month from the museum's closing. More about the Frank H. Woods Telephone Pioneer Museum and its closing here: * https://journalstar.com/news/local/the-frank-h-woods-telephone-museum-ringing-off-for-the/article_81986c7d-c3dd-5b72-92ea-d0cca128f460.html * https://journalstar.com/news/local/history-lost-with-permanent-closing-of-lincoln-s-frank-h/article_c28842ae-77b8-5af9-8af6-b9c25e998a41.html

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.

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.
