Courtesy Telephone
A courtesy telephone is a telephone located in airport terminals, large train stations, hotel lobbies, and other places where many travellers are expected, which is used to relay messages to a specific person. It is typically used in connection with a public address system announcement of the style "Gwen Cooper, please pick up the nearest white courtesy telephone." Courtesy telephones may have a distinctive color, which is traditionally white in US airports, and most have no dialing capabilities but rather are simple ringdown In telephony, ringdown is a method of signaling an operator in which telephone ringing current is sent over the line to operate a lamp or cause the operation of a self-locking relay known as a ''drop''. Ringdown is used in manual operation, ... stations to reach an operator or other fixed number. Some double as emergency telephones, having buttons by which a user can distinguish between emergency use and inquiry. Customers can use a courtesy phone ...

White Courtesy Phone Crop
White is the lightness, lightest color and is achromatic (having no colorfulness, chroma). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully (or almost fully) diffuse reflection, reflect and scattering, scatter all the visible spectrum, visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France as well as the flag of Bourbon Restoration in France, monarchist France from 1815 to July Revolution, 1830, and of the White movement, monarchist movement that opposed the Bolsheviks during the Ru ...

Courtesy Phone, Telephone Book, And Pencils - Missoula Public Library
Courtesy (from the word , from the 12th century) is gentle politeness and courtly manners. In the Middle Ages in Europe, the behaviour expected of the nobility was compiled in courtesy books. History The apex of European courtly culture was reached in the Late Middle Ages and the Baroque period (i.e. roughly the four centuries spanning 1300–1700). The oldest courtesy books date to the 13th century, but they become an influential genre in the 16th, with the most influential of them being '' Il Cortegiano'' (1508), which not only covered basic etiquette and decorum but also provided models of sophisticated conversation and intellectual skill. The royal courts of Europe persisted well into the 18th century (and to some limited extent to the present day), but in the 18th century, the notion of ''courtesy'' was replaced by that of '' gallantry'', referring to an ideal emphasizing the display of affected sensitivity in direct contrast with the ideals of self-denial and dignified ...

Telephone
A telephone, colloquially referred to as a phone, is a telecommunications device that enables two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via Electrical cable, cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from and (, ''voice''), together meaning ''distant voice''. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a microphone (''transmitter'') to speak into and an earphone (''receiver'') which reproduces the voice a ...

Airport Terminal
An airport terminal is a main building at an airport where passengers transfer between ground transportation and the facilities that allow them to board and disembark from an Fixed-wing aircraft, aircraft. The buildings that provide access to the airplanes (via Gate (airport), gates) are typically called concourses. However, the terms "terminal" and "concourse" are sometimes used interchangeably, depending on the configuration of the airport. Smaller airports have one terminal while larger airports have several terminals and/or concourses. At small airports, a single terminal building typically serves all of the functions of a terminal and a concourse. Larger airports might have either one terminal that is connected to multiple concourses or multiple almost independent unit terminals. By the end of the 20th century airport terminals became symbols of progress and trade, showcasing the aspirations of nations constructing them. The buildings are also characterized by a very rap ...

Ringdown
In telephony, ringdown is a method of signaling an operator in which telephone ringing current is sent over the line to operate a lamp or cause the operation of a self-locking relay known as a ''drop''. Ringdown is used in manual operation, and is distinguished from automatic signaling by dialing a number. The signal consists of a continuous or pulsed alternating current (AC) signal transmitted over the line. It may be used with or without a telephone switchboard. The term originated in magneto telephone signaling in which cranking the magneto generator, either integrated into the telephone set or housed in a connected ringer box, would not only ''ring'' its bell but also cause a drop to fall ''down'' at the telephone exchange switchboard, marked with the number of the line to which the magneto telephone instrument was connected. At the end of the conversation, one participant would crank to ''ring off'', signaling the operator to take down the connection. In modern Briti ...

Switchboard Operator
In the early days of telephony, companies used manual telephone switchboards, and switchboard operators connected calls by inserting a pair of phone plugs into the appropriate jacks. They were gradually phased out and replaced by automated systems, first those allowing direct dialing within a local area, then for long-distance and international direct dialing. Description A typical manual telephone switchboard has a vertical panel containing an array of jacks with a desk in front. The desk has a row of switches and two rows of plugs attached to cables that retract into the desk when not in use. Each pair of plugs was part of a cord circuit with a switch associated that let the operator participate in the call or ring the circuit for an incoming call. Each jack had a light above it that lit when the customer's telephone receiver was lifted (the earliest systems required the customer to hand-crank a magneto to alert the central office and, later, to "ring off" the completed ca ...

Emergency Telephone
An emergency telephone is a public telephone provided for making calls to emergency services. Roadside emergency telephones Although it is difficult to determine when and where the earliest highway emergency phones were developed, undoubtedly one of the earliest examples were the freeway phones developed in Western Australia in 1966. This system was developed by Alan Harman, an employee of a Western Australian security firm, Central Station Security Company, Electronic Signals Pty Ltd, who came up with the idea after reading of a pile-up on the Kwinana Freeway. The newspaper article mentioned that assistance had been difficult to provide to those involved in the pile-up. The system Harman envisaged was a series of telephone units in a box on a short post, spaced every on Perth's freeways. Picking up the handset would trigger an alarm in the Main Roads control centre and police, fire or ambulance could then be determined by the caller. Harman developed the system with the approv ...
