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? Tell people what it is and what they can see by writing something for example: "01:00:12:00 -- President Roosevelt is seen meeting with Winston Churchill at the Quebec Conference."

On the value and principles of the coaxial cable. Explains how the coaxial carries many conversations at once and how calls over long distances are amplified by repeater stations. Shows details in the manufacture of coaxial cable. The first commercial stretch of cable is laid between Stevens Point, Wisc., and Minneapolis, Minn."

Many coaxial cables also have an insulating outer sheath or jacket. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who patented the design in 1880. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line... Coaxial cable conducts electrical signal using an inner conductor (usually a solid copper, stranded copper or copper plated steel wire) surrounded by an insulating layer and all enclosed by a shield, typically one to four layers of woven metallic braid and metallic tape. The cable is protected by an outer insulating jacket. Normally, the shield is kept at ground potential and a voltage is applied to the center conductor to carry electrical signals. The advantage of coaxial design is that electric and magnetic fields are confined to the dielectric with little leakage outside the shield. Conversely, electric and magnetic fields outside the cable are largely kept from causing interference to signals inside the cable. Larger diameter cables and cables with multiple shields have less leakage. This property makes coaxial cable a good choice for carrying weak signals that cannot tolerate interference from the environment or for stronger electrical signals that must not be allowed to radiate or couple into adjacent structures or circuits. Common applications of coaxial cable include video and CATV distribution, RF and microwave transmission, and computer and instrumentation data connections...

The generations of telephone switches before the advent of electronic switching in the 1950s used purely electro-mechanical relay systems and analog voice paths. These early machines typically utilized the step-by-step technique. The first generation of electronic switching systems in the 1960s were not entirely digital in nature, but used reed relay-operated metallic paths or crossbar switches operated by stored program control (SPC) systems. First announced in 1955, the first customer trial installation of an all-electronic central office commenced in Morris, Illinois in November 1960 by Bell Laboratories. The first prominent large-scale electronic switching system was the Number One Electronic Switching System (1ESS) of the Bell System in the United States, introduced in Succasunna, New Jersey, in May 1965. Later electronic switching systems implemented the digital representation of the electrical audio signals on subscriber loops by digitizing the analog signals and processing the resulting data for transmission between central offices. Time-division multiplexing (TDM) technology permitted the simultaneous transmission of multiple telephone calls on a single wire connection between central offices or other electronic switches, resulting in dramatic capacity improvements of the telephone network... In the late 20th century most telephone exchanges without TDM processing were eliminated and the term electronic switching system became largely a historical distinction for the older SPC systems...

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.

How To Correctly Answer a TELEPHONE !!!
Today i will show you how to correctly answer a telephone. Hope this tutorial was helpful. Comment, Like and Subscribe. A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. The word telephone has been adapted into the vocabulary of many languages. It is derived from the Greek: τῆλε, tēle, far and φωνή, phōnē, voice, together meaning distant voice. First patented in 1876 by Alexander Graham Bell and further developed by many others, the telephone was the first device in history that enabled people to talk directly with each other across large distances. Telephones became rapidly indispensable to businesses, government, and households, and are today some of the most widely used small appliances. The essential elements of a telephone are a microphone (transmitter) to speak into and an earphone (receiver) which reproduces the voice of the distant person. In addition, most telephones contain a ringer which produces a sound to announce an incoming telephone call, and a dial used to enter a telephone number when initiating a call to another telephone. Until approximately the 1970s most telephones used a rotary dial, which was superseded by the modern Touch-Tone push-button dial, first introduced by AT&T in 1963. The receiver and transmitter are usually built into a handset which is held up to the ear and mouth during conversation. The dial may be located either on the handset, or on a base unit to which the handset is connected by a cord containing wires. A landline telephone is connected by a pair of wires to the telephone network, while a mobile phone, such as a cellular phone, is portable and communicates with the telephone network by radio transmissions. A cordless telephone has a portable handset which communicates by radio transmission with the handset base station which is connected by wire to the telephone network. The transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. The receiving telephone converts the signals into audible sound in the receiver, or sometimes a loudspeaker. Telephones are a duplex communications medium, meaning they allow the people on both ends to talk simultaneously. The telephone network, consisting of a worldwide net of telephone lines, fiberoptic cables, microwave transmission, cellular networks, communications satellites, and undersea telephone cables connected by switching centers, allows any telephone in the world to communicate with any other. Each telephone line has an identifying number called its telephone number. To initiate a telephone call the user enters the other telephone's number into a numeric keypad on the phone. Graphic symbols used to designate telephone service or phone-related information in print, signage, and other media include ℡ (U+2121), ☎ (U+260E), ☏ (U+260F), ✆ (U+2706), and ⌕ (U+2315). Although originally designed for simple voice communications, most modern telephones have many additional capabilities. They may be able to record spoken messages, send and receive text messages, take and display photographs or video, play music, and surf the Internet. A current trend is phones that integrate all mobile communication and computing needs; these are called smartphones.

Operator Toll Dialing #2 "Cord Signals" ~ (1949) Bell System Long Distance Telephone
Instructional film for telephone operators. Produced for AT&T by Audio Productions. http://phones.quickfound.net/telephone_operator_girls_1899.html - The New York Times, June 11, 1899, p.IMS10: - HELLO! THE TELEPHONE GIRL. - The average man might do much worse than court a telephone girl of New York. This is an opinion carefully formed after a study of the various exchanges, after several sessions of listening in by the side of on and another in active service, after chats here and there with chief operators. - For the Miss behind the telephone, whose voice is most frequently heard in the query, "What number, please?"--she is, as a rule, a slip of a girl, barely twenty oftentimes--is a very capable young person, indeed. The writer feels inclined to put her at the head of New York's army of working girls, for her brisk intelligence, her gentle ways, and the deft way she uses her small hands... - An exchange presents an interesting sight. About three sides of the great room, reaching very nearly to the ceiling, set in a structure that reminds one of an inner shell or wall, is a switchboard, with its projecting ledge. Along it, as closely as comfort will allow, are girls, and yet more girls. In a never-broken line they stretch on, over a hundred at a time, in an exchange like Cortlandt, girls tall and short, full-fledged women and round-faced lassies just out of the schoolroom, girls of dainty face and contour, and girls whom fate has dealt less kindly with, girls half-shabby and girls of pretty costume with wonderful little aprons about their waists. Nothing more or less than a concourse of youthful femininity that interests because of the marked diversity of the types shown... - If it were permitted to chat with subscribers, to gossip with each other, the telephone girls would have no time. It is nothing unusual for an expert operator to answer 125 calls an hour. She may even answer 150, or two and a half a minute. On the trunk lines, where the process is simpler and where exchanges are joined (a man on Broad wanting to speak to a man on Thirty-eighth Street, for example,) as many as 600 connections are often made in an hour. - Sometimes for five full minutes it is a mad race with the girl at the case to attend to all the demands made upon her. Perhaps, at certain hours of the day, things may calm down, and her hands, for a moment or two, lie idly in her lap. But even then she must be on the que vive for new calls, her eyes on the lookout. - Contrary to the belief of the public, a bell does not warn the telephone girl when the customer rings up "central." A little metal disk falls, displaying the subscriber's number, and that only, with no sound, with hardly a stir... - One of the disks of a drop falls, and the number is displayed. Quick as thought the girl takes up a plug (which itself fits in a hole, its long cord falling even below the floor,) and sticks it sharply in the hole whose number corresponds with the number on the disk. At the same instant she has thrown the little lever on a line with the plug's hole, and is already asking "What number, please?" - If the number that comes to her ears is of the same exchange what remains to be done is simple. The plugs spoken of go in pairs. She has only to pull out its mate, and push it in the proper hole. Then throwing another cam she presses the corresponding ringing button. That rings the bell for the party called. She listens sharply for an instant, then announcing "All right. Go ahead." - Her swiftly flying fingers are already busy with another call. One of her subscribers has called for a number on another exchange. She has the plug for his wire already in place, of course, but a more complicated connection is now to be made. - She presses a calling circuit button on the ledge. This brings to her aid another operator, a girl at the Trunk Line switchboard, of the distant exchange. "1029 Broad," she remarks quietly through her transmitter. More quickly than the word can be written a number comes back, 10. This is the number of the hole in her switchboard in to which her second plug must go to get the Broad Street connection.

Telephone History & Future Technology:  "The Far Sound" 1973 AT&T-Bell System
Telephones & Telephony playlist: https://www.youtube.com/playlist?list=PL291BE0923F33CEB1 American History, US History, United States History Playlist: https://www.youtube.com/playlist?list=PL52C3C9693B350335 more at http://quickfound.net/ 'Host Fred Holiday, Director Jerry London, Producer: George B. Seitz, Jr.; Writer: Anthony Baker... psychedelic opening educational film about telecommunications with exploration of future technologies like fiber optics & lasers...' Originally a public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Repeater Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ A repeater is an electronic device that receives a signal and retransmits it at a higher level or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances... Usage Repeaters are used to boost signals in coaxial and twisted pair cable and in optical fiber lines. An electrical signal in a cable gets weaker the further it travels, due to energy dissipated in conductor resistance and dielectric losses. Similarly a light signal traveling through an optical fiber suffers attenuation due to scattering and absorption. In long cable runs, repeaters are used to periodically regenerate and strengthen the signal... History Before the invention of electronic amplifiers, mechanically coupled carbon microphones were used as amplifiers in telephone repeaters. After the turn of the century it was found that negative resistance mercury lamps could amplify, and they were used. The invention of the audion tube in 1906 made transcontinental telephony practical. In the 1930s vacuum tube repeaters using hybrid coils became commonplace, allowing the use of thinner wires. In the 1950s negative impedance gain devices were more popular, and a transistorized version called the E6 repeater was the final major type used in the Bell System before the low cost of digital transmission made all voiceband repeaters obsolete. Frequency frogging repeaters were commonplace in frequency-division multiplexing systems from the middle to late 20th century. http://en.wikipedia.org/wiki/Long-distance_calling ...In 1892, AT&T built an interconnected long-distance telephone network, which reached from New York to Chicago, the technological limit for non-amplified wiring. Users often did not use their own phone for such connections, but made an appointment to use a special long-distance telephone booth or "silence cabinet" equipped with 4-wire telephones and other advanced technology. The invention of loading coils extended the range to Denver in 1911, again reaching a technological limit. A major research venture and contest led to the development of the audion—originally invented by Lee De Forest and greatly improved by others in the years between 1907 and 1914—which provided the means for telephone signals to reach from coast to coast. Such transcontinental calling was made possible in 1914 but was not showcased until early 1915, as a promotion for the upcoming Panama-Pacific Exposition in San Francisco in the spring of the same year. On 25 January 1915, Alexander Graham Bell ceremonially sent the first transcontinental telephone call from 15 Dey Street in New York City, which was received by his former assistant Thomas A. Watson at 333 Grant Avenue in San Francisco. This process, nevertheless, involved five intermediary telephone operators and took 23 minutes to connect...

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

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In telecommunication, a two-wire circuit is characterized by supporting transmission in two directions simultaneously, as opposed to four-wire circuits, which have separate pairs for transmit and receive. In either case they are twisted pairs. Telephone lines are almost all two wire, while trunks and switching are almost entirely four wire. To communicate in both directions in the same wire pair, conversion between four-wire and two-wire is necessary, both at the telephone and at the central office. A hybrid coil accomplishes the conversion for both. At the central office, it is part of a four-wire terminating set, more often as part of a line card. Because the same twisted pair carries telephone signals in both directions, echo is often a problem on these circuits. Echo is avoided by ensuring matching impedance at both ends of the circuit. Different countries have different standards for telephone impedance.

How does wiretapping work?
It’s surprisingly easy to listen to private conversations if you know how to hack satellites, bug devices or tap a phone line. Learn more at HowStuffWorks.com: http://people.howstuffworks.com/wiretapping.htm Share on Facebook: Share on Twitter: Subscribe: http://goo.gl/ZYI7Gt Visit our site: http://www.brainstuffshow.com Hello there BrainStuff. I’m Jonathan Strickland and I’ll be listening in on your private conversations today… What’s that? Privacy?! Ha! But I’ll tell you what… how about I teach you how to listen in too? Without getting into all the legality, history or ethics of it, let’s look at how wiretapping works. Now there’s many ways to tap into a phone call. I’d be remiss if I didn’t at least acknowledge that a multimillion-dollar market exists where governments pay phone companies to patch them in and record your calls. Or that it’s also possible to hack into satellites that transmit phone signals. But since we’ve only got limited time, let’s talk about what’s called the “roving bug” method of wiretapping a mobile call. The FBI and other intelligence agencies have made use of this technique, by remotely activating a handset’s microphone so they can eavesdrop on any conversation nearby, sometimes whether your phone is powered on or not. All it requires is a bit of software downloaded to the device that modifies the interface displaying when a call is in progress. This “spyware” then places a call to the eavesdropper, activating the microphone without the owner ever even knowing. The only practical way to avoid this is to routinely peel the battery out of your phone. Or you could buy a continuing supply of cheap, prepaid burner phones. Haven’t you seen “The Wire?” Oh! But you want to know how to tap a phone the old fashioned way, by bugging a landline? The earliest versions of this were simply extra wires connected to the line between your phone and the telephone company. The line’s circuit carries your conversation as electrical current fluctuations, representing the air-pressure of sound waves. Wiretaps convert the electrical information on the line back into sound that can be listened to or recorded. You could even use a bug that transmits the audio information as radio waves to a nearby receiver. Y’know, the standard agent-parked-in-a-van-listening-to-headphones routine. As with any circuit, you can hook up components anywhere along the line. It’s like adding an extra phone jack in your house. The easiest way, is to attach another phone somewhere along the line. You do this by cutting one of the modular plugs off of a phone cord so its red and green wires are exposed. Next you attach the exposed wires to their corresponding colors at an accessible point on the outside line. This can be anywhere along the entire length of wire, even on a clip at a junction box. Once it’s attached, just plug the cord into your phone tap and start listening! But a few tips before you start wiretapping. First of all, it’s… y’know… illegal. Second, disable the tap’s microphone so the subject won’t hear you breathing on the other end. And, so you don’t have to wait around for someone to pick up the phone, you can use a voice-activated recorder for dictation to capture when they start talking. When the line goes dead, it’ll just turn itself off.

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. AT&T also reviewed MrMobile's final script for technical accuracy, but no editorial changes were made as a result of the company's input. Travel expenses were entirely paid by MrMobile/Mobile Nations, and there was no consideration paid to MrMobile by AT&T for the production of this video.

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

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.

Faking It: The Obviously Dubbed Telephone Ring
If you lived in North America any time in the 20th century, you probably ran across one of these telephones. The Western Electric Model 500 and its subsequent variants were so ubiquitous that you almost couldn't go anywhere without seeing one, especially in the United States where it was standard equipment from the phone company. Even if you're not American, if you've seen any of our movies, you'll have seen this phone, too. A literal fixture of American life, this phone was inescapable. But its ubiquity also caused some filmmakers or TV show producers to get a little lazy. This video tells that story. Here's a link to the video of the Model 500 from 1958. Yes I said 1957 in the video. I am truly sorry. My oversight is abhorrent. I am ashamed. https://www.youtube.com/watch?v=9X99nfA4oGM You can support this channel on Patreon!
