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

“Communications: The Story of Communications” is a 1947 20th Century Fox black-and-white production explaining the importance of communication to mankind. Narrated by radio and television announcer Nelson Case, the film opens with scenes of street celebrations at mark 00:50 as residents celebrate news of an unidentified event (though likely the end of World War II). Printing presses run off newspaper copies as newsboys rush into the streets, “shouting a story that everyone knows already.” Scenes of wireless radio sending the news around the world follows at mark 1:50, and even in the deepest jungles, “centuries are bridged as the story carried by radio is picked up by the sound of ancient drums.” Drums, were are told, were some of mankind’s earliest forms of communication as their sound carried news long distances. Written languages (shown in the form of hieroglyphics) follows at mark 02:52, as are handwritten Greek scrolls and Roman tablets, until Johannes Gutenberg’s invention of the movable-type printing press in the 15th century. The film continues to trace the history of communication, including a nod to the use of carrier pigeons at mark 03:45, cannon shots, and smoke signals. We learn of messages in the Old West sent via stagecoach or the Pony Express until the coming of the telegraph (mark 05:35) in 1840 by Samuel Morse. By the early 19th century the telegraph pole was part of the American landscape, stretching from the Eastern seacoast to California. That changed in 1876 with the patenting of the telephone by Alexander Graham Bell as we see a room of switchboard operators at mark 06:28 and the stretching of telephone wire across the country. Underground and underwater transcontinental cables follow, as does a discussion of the first signals of wireless radio used in 1895 (mark 08:10) by Guglielmo Marconi. He would go on to be credited as the inventor of a new medium — radio. America’s first commercial broadcasts would follow in the 1920s, we’re told at mark 09:25, carrying news and entertainment to homes. “Another fantastic communication dream that came true is television,” the audience is told at mark 10:57, as narrator praises the idea of broadcasting pictures — like sound — through the air and we see images of football games and newsreel footage. An early TV is shown. The importance of a teletype machine in getting news to a newsroom and out to the public is covered at mark 12:15. Even when those links are broken, work crews stand at the ready to repair them, we are told, to continue the never-ending flow of communications. We encourage viewers to add comments and, especially, to provide additional information about our videos by adding a comment! See something interesting?

Old open wire telephone lines at Parks new South Wales, filmed in 2006 but now removed. Not many of these left now, you would think Parks with it's history of technology for the part it played in the moon landings would have preserved this. I know that a microwave data link was set up between the dish at Parks and Sydney but in any event a lot of telephone and telex traffic to do with one of mans greatest achievements would have taken place over these wires It is well known that the first few minutes of the moon vision came from the honeysuckle creek tracking station near Canberra but that has been demolished for a while. Each time i passed these lines and that was not to often once in every few years i would say i must take some photos before they are pulled or fall down but it was always to dark or no film etc. In 2006 i did have a HD video cams and did spend some time getting some of it to tape, went back this year 2009 for the 40th anniversary of the 1st manned landing on the moon and was going to get some hi res stills but they were all gone in the cause of street beautification. Don't even try to watch in HD unless you have a very fast connection and a good computer.

Hi, this 'How To' video shows how to run a phone line down a cat5 or cat6 network wiring using an empty port. In this example it runs from the phone line into a network socket using a 1m BT to RJ45 lead then over to the patch panel under the stairs. It then links through on the patch panel using a short patch lead to connect together the living room port and the kitchen port. Then in the kitchen network socket it terminates with a PABX RJ45 to BT socket adaptor. If your phone line was already by the patch panel under the stairs then the run would be shorter as it would go from the phone line straight into the patch panel and then onto the kitchen. On a 10/100 BASE-TX network then you can use economisers to push phone and Ethernet down the one cat5 cable. I will show this in a future video.

Shark Bites Fiber Optic Cables Undersea 15.8.2014
Google is reinforcing its underwater fibre-optic cables to protect against future shark attacks Google is reinforcing its private underwater fibre-optic cables with an extra layer of protective material in order to protect its 100,000 miles of cables from sharks. Sharks and other fish are attracted to the cables, thought by some to be due to the electromagnetic signals emitted by the lines, but they are easily damaged. The cables already have existing protective materials designed to shelter them from the various dangers of the environment, but will now be coated with a 'Kevlar-like' material to provide even more protection. Fibre-optic cables are made of strands of glass, and are thus much less durable than copper cables. Google wants to prevent its own cables from sustaining further damage after seeing underwater surveillance footage of sharks biting the cables. IT Pro has contacted Google for more information on the plans and will update the story as soon as we know more.

guided media in hindi || twisted pair cable || coaxial cable || optical fiber cable
GUIDED MEDIA or WIRED MEDIA :- -Electrical/Optical signals are passed through a solid medium (different types of cables/wires) -As the path traversed by the signals is guided by the size, shape and length of the wire, this type of media is called guided media. -Also, in guided media, the signals are confined within the wire and do not propogate outside of the wire/media. -E.g., Copper Unshielded Twisted Pair (UTP), Copper Shielded Twisted Pair (STP), Copper Co-axial cables, Fiber Optic Cables. Twisted Pair Copper: -It is the most widely deployed media type across the world, as the last mile telephone link connecting every home with the local telephone exchange is made of twisted pair copper. These telephone lines are reused as last mile DSL access links to access the internet from home. -They are also used in Ethernet LAN cables within homes and offices. They support low to High Data Rates (in order of Giga bits) However, they are effective only upto a maximum distance of a few kilometres/miles, as the signal strength is lost significantly beyond this distance. -They come in two variants, namely UTP (unshielded twisted pair) and STP (shielded twisted pair). Within each variant, there are multiple sub-variants, based on the thickness of the material (like UTP-3, UTP-5, UTP-7 etc.) -E.g. DSL, 10/100/1000Mbps Ethernet cables Copper Co-axial Cables -Co-axial copper cables have an inner copper conductor and an outer copper shield, separated by a di-electric insulating material, to prevent signal losses. -It is primarily used in cable TV networks and as trunk lines between telecommunication equipments. -It serves as an internet access line from the home. -It supports medium to High Data Rates -It has much better immunity to noise and hence signal strength is retained for longer distances than in copper twisted pair media. Fiber Optic Cables -Here, information is transmitted by propogation of optical signals (light) through fiber optic cables and not through electrical/electromagnetic signals. Due to this, fiber optics communication supports longer distances as there is no electrical interference. -As the name indicates, fiber optic cables are made of very thin strands of glass (silica). -As they support very high data rates, fiber optic lines are used as WAN backbone and trunk lines between data exchange equipments. -They are also used for accessing internet from home through FTTH (Fiber-To-The-Home) lines. -Additionally, they are used even for LAN environment with different LAN technologies like Fast Ethernet, Gigabit Ethernet etc. using optical links at the physical layer. - OC-48, OC-192, FTTC, HFC are examples of Fiber Optical links.

AT&T Archives: Design Line Fashions
Watch more AT&T Archive films at http://techchannel.att.com/archives For much of the company's history, AT&T rented phones to users. But in the 1970s, the company tried a novelty line of phones that customers could actually buy, in stores. For these "Design Line" phones, the users were essentially buying just the housing — the working guts of the phones were still under the Bell System maintenance and ownership contracts. This film profiles the range of models available in 1979 — both push-button and dial telephones, including the "Snoopy", "early American", "stowaway", "celebrity", "Mediterranean", "candlestick", "chestphone", "antique gold", "Mickey Mouse", "noteworthy", "coquette", "Telstar", and the popular "Exeter", which had interchangeable faceplates, including a crazy rainbow diffraction grating option. You not only get to see the imagined home décor that would have gone with these phones, but who the Bell System imagined was the ideal user for each. These phones were not cheap — prices in 1976 for these phones ranged from $39.95 for the basic Exeter to a whopping $109.95 for the rococo Antique Gold model. That's about $150 to over $400 today. Not that much more than a smartphone, but, of course, no touchscreen. No ringtones. These phones were manufactured in Western Electric's Indianapolis Works (for another view of the Works, see the film Draw Me A Telephone. The Bell System kept the Design Line series running for a few more years after this film, introducing only a few new telephone models throughout the 1980s. After the breakup of the Bell System, the Works were closed in 1986. They even released a commemorative Design Line phone to mark the occasion.

How Cell Towers Work: Hands-On!
Fun fact: when I was selling mobile phones back in 2004, I would spend the store's slow days taking online training courses reserved for my employer's engineers, fascinated by the networks that made mobile phones work. Twelve years (and a change of career) later, my network curiosity still burned strong. So I asked AT&T to let me go hands-on with a cell site – and to my great surprise, the carrier said yes! Come along as I scope out not one, but two cell sites: one hidden in the steeple of a church, the other perched high atop the tallest mountain in the Northeast. In the process we'll learn about RF energy, what happens when the power goes out, and why the term "tower" isn't always accurate. [SUBSCRIBE] https://www.youtube.com/channel/UCSOpcUkE-is7u7c4AkLgqTw?sub_confirmation=1 [ABOUT THIS VIDEO] MrMobile's Tower Tour was produced based on a pitch by MrMobile to AT&T in the Spring of 2016. To make this video possible, AT&T provided access to two cell sites and several network engineering personnel.

Most homes, even older homes, are prewired with telephone cabling which can be quite easily converted to ethernet. Since 100mbs ethernet only uses 4 of the 8 wires normally found in an ethernet cable, even old 4 wire cat 3 telephone cabling can be wired for ethernet.

Increase your Internet Broadband Speed by 60% by using an ADSL faceplate and ADSL extension.
Hi, this 'How To' video shows a real example of an increase in internet ADSL broadband speed of over 60%. It is ideal if you want to fit an ADSL or VDSL faceplate but your router is located nowhere near your master socket. It shows you how to use your existing telephone extensions to provide a dedicated ADSL or VDSL extension which can help increase your broadband speed because the signal can degrade as it travels through voice telephone extension wiring. It is always best to install your router by your master socket but if this is not possible then follow the steps in this video. By using the setup in this video you stop the broadband signal travelling down the voice extensions and allow it to travel down a twisted pair of wires to the location of your router. In the UK master sockets are often located in the hallway because historically people had a single telephone in the hallway but this is not the ideal place for a router as most people want the router hidden away or next to the computer. In the video the router stats which shows what the line is capable of achieving went up over 60% but the actual results on speedtest.net stayed the same but this is due to DLM (Dynamic Line Management) which on Plusnet broadband can take up to 3 days to change so within 3 days of this video the actual speedtest.net speed would increase in line or just below the actual router stats. In hindsight I should have shown the before and after router stats page but I didn't BUT I did note down the results as a comparison. Thanks for watching. Many thanks Vince

FAQ - What's The Difference Between Modular Plugs?
http://www.showmecables.com/ Hello, and welcome to Show Me Cables. Today we’re going to take a look at the difference between modular plugs. Modular plugs are used in many different voice, data, and control signals and are available in a variety of styles. The first plug we have is known as an RJ22. This is the smallest of the modular plugs and is mostly used on handset cords. It is known as a 4P4C, which means that it has 4 positions and 4 contacts. The RJ11 is slightly larger than the RJ22 and found on line cords, used for telephone wall plates and control signals. It is known as 6P4C, which means that it has 6 positions and 4 contacts. The RJ12 is the same size as an RJ11 and is also found on many line cords and is commonly used for telephone and control applications. However, the RJ12 is a 6P6C, meaning that it has 6 positions and 6 contacts. RJ12 connectors can be used in place of RJ11 applications, but RJ11 may or may not work in place of RJ12, depending on if the additional 2 contacts are needed. RJ45 connectors are slightly larger than the RJ12s and are used for Ethernet and data applications. They are known as an 8P8C, which means that it has 8 positions and 8 contacts. If you still have any questions, you can call our customer service department at 888-519-9505.

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.

What is LINE SIGNALING? What does LINE SIGNALING mean? LINE SIGNALING meaning & explanation
What is LINE SIGNALING? What does LINE SIGNALING mean? LINE SIGNALING meaning - LINE SIGNALING explanation - LINE SIGNALING definition. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Line signaling is a class of telecommunications signaling protocols. Line signaling is responsible for off-hook, ringing signal, answer, ground start, on-hook unidirectional supervision messaging in each direction from calling party to called party and vice versa. After an off-hook, line signaling initiates register signaling to accomplish the exchange of telephone numbers of called party and in more modern line-signaling protocols, the calling party as well. While register signaling occurs, line signaling remains quiescent unless the calling party goes on-hook or an abnormal cessation of the call occurs, such as due to equipment malfunction or shutdown or due to network outage upstream in that call-attempt's series of spanned trunks. Line signaling can be conveyed in a single DS0 channel of a trunk. In modern PCM telecommunications, line signaling is represented by the ABCD bits in DS0 #16 of an E1 or a selected DS0 within a T1. Line signaling can also be conveyed within the channels being supervised, as in the original T1 scheme which used one out of every eight bits for supervision, or with robbed bits of a superframe format, or as in-band signaling, e.g. as in L1 signaling where 2280 Hz tone pulses are used.

What is Phone Line Monitoring?
In this video, Jorge talks about phone line monitoring and how it works. A panel that uses phone line monitoring will dial out to a central station when an alarm event occurs. The phone number for the central station will be programmed into the panel, and the signal will be sent across a phone line. Phone lines have been used with alarm systems for a very long time. Before WIFI and cellular technology became prevalent, phone lines represented the leading method for a security system to send outbound signals. But today, phone lines are less commonly used. The most common reason for a user to have a phone line set up for monitoring is because they have an existing alarm system that hasn't been upgraded. While this will continue to work in most cases, there are many reasons why a user would not want to use phone line monitoring. First, a building has to have active telephone service in order for phone line monitoring to be used. These days, a large percentage of households have dropped phone service, and they rely exclusively on cell phones for communication. Adding phone service just to get an alarm system is not very practical, and it is largely unnecessary. Second, phone service is a relatively slow form of communication. This means it will take longer for the central station to respond to emergencies when using phone line monitoring. Third, phone lines are unreliable. Every time a signal is sent out across a phone line, it is possible that it will not reach its intended destination. Fourth, a potential intruder can physically cut a phone line so that the system cannot dial out. Fifth, a system that uses a phone line cannot be used with any interactive service platforms, such as Total Connect 2.0 or Alarm.com, for remote access and control. Instead of a phone line, it is much better to use a cellular or IP connection with an alarm system. And if a system does have a phone dialer, they can usually upgrade it to use cellular communication by using a universal cellular communicator like a Telguard TG-1 Express. This module will take over the system's dialer and have it actually connect with a cellular network. http://alrm.gd/get-monitored

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.

In all cases, the turn signal switch is also in charge of the hazard lights and to make matters worse, the hazard and the turn signal switch is often a separate unit. Here in this section, we'll not concentrate on the hazard switch, but simply explain how to wire the entire turn signal system. The idea is to offer a way to make the turn signals operational if you have no parts available, due to the vehicle being out of the parts market, being too rare or just due to the high costs. In actuality, this wiring arrangement can be used even if you have no turn signal switch, which would then be substituted using standard buttons or flip switches. This circuit also employs a regular flasher unit right at the 12 volt input. The flasher unit feeds both relays. This is done for the sake of efficiency and to reduce costs. The only drawback to using one flasher is that whenever the hazard is activated, the lights will flash at a faster rate. Let's analyze this circuit: Power is fed from the 12 volt supply, through the fuse and to one side of the flasher unit. The other side of the flasher feeds terminals....
