Area Code 819
Area codes 819, 873, and 468 are overlay telephone area codes in the North American Numbering Plan (NANP) for central and western Quebec, Canada, including the Quebec portion of the National Capital Region, and the Hudson Strait and Ungava Bay coastlines of Quebec. Major cities in the territory include Gatineau, Sherbrooke, Trois-Rivières, Drummondville, Shawinigan, Victoriaville, Rouyn-Noranda, Val-d'Or, Magog and Mont-Laurier. The incumbent local exchange carriers for the numbering plan area are Bell Canada, Bell Aliant, Telus, as well as Télébec and other independent companies. From 1992 to 1997, Northwestel was also an incumbent carrier in 819, as it included former Bell Canada areas in the Northwest Territories. History Ontario and Quebec were the only Canadian provinces that received assignments of multiple area codes from the American Telephone and Telegraph Company (AT&T) when the original North American area codes were created in 1947.

Overlay Plan
In telecommunications, an area code overlay complex is a telephone numbering plan that assigns multiple area codes to the same geographic numbering plan area (NPA). Area code overlays are implemented in territories of the North American Numbering Plan (NANP) to mitigate exhaustion of central office codes in growth areas. The method has been in use since 1992, and has been the exclusive method of area code relief since 2007. History From the inception of the North American Numbering Plan in 1947 until 1992, the only method of introducing new area codes was the area code split. It divided an existing numbering plan area (NPA) into multiple regions, one of which retained the existing area code. The other parts were each assigned a new NPA code. The retaining area was usually the historically more established or developed place, and required no numbering changes. It gained numbering capacity by acquiring the central office codes of the other areas, because those were delegated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Area Code 613
Area is the measure of a region's size on a surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while ''surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). Two different regions may have the same area (as in squaring the circle); by synecdoche, "area" sometimes is used to refer to the region, as in a "polygonal area". The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square ...

Montreal
Montreal is the List of towns in Quebec, largest city in the Provinces and territories of Canada, province of Quebec, the List of the largest municipalities in Canada by population, second-largest in Canada, and the List of North American cities by population, ninth-largest in North America.

Flash Cut
A flash cut, also called a flash cutover, is an immediate change in a complex system, with no phase-in period. In the United States, some telephone area codes were split or overlaid immediately, rather than being phased in with a permissive dialing period. An example is telephone area code 213, which serves downtown Los Angeles and its immediate environs, split in January 1951 into 213 and 714 all at once. Another example is an immediate switch from an analog television channel to a digital television channel on the same frequency, where the two cannot operate in parallel without interference. A flash cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period. In film, an extremely brief shot, sometimes as short as one frame, which is nearly subliminal in effect. Also a series of short staccato shots that create a rhythmic effect.

Original North American Area Codes
The original North American area codes were established by the American Telephone and Telegraph Company (AT&T) in 1947. The assignment was in accord with the design of a uniform nationwide telephone numbering plan that supported the goal of dialing any telephone in the nation without involvement of operators at each routing step of a telephone call from origination location to its destination. The new technology had the aim of speeding the connecting times for long-distance calling by eliminating the intermediary telephone operators and reducing cost. It was initially designed and implemented for Operator Toll Dialing, in which operators at the origination point would dial the call as instructed by service subscribers, but had also the benefit of preparing the nation for Direct Distance Dialing (DDD) by customers years later. The nationwide and continental application followed the demonstration of regional Operator Toll Dialing in Philadelphia during the World War II period. The ne ...

American Telephone And Telegraph Company
AT&T Corporation, an abbreviation for its former name, the American Telephone and Telegraph Company, was an American telecommunications company that provided voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies. During the Bell System's long history, AT&T was at times the world's largest telecommunications company, the world's largest cable television operator, and a regulated monopoly. At its peak in the 1950s and 1960s, it employed one million people and its revenue ranged between US$3 billion in 1950 ($ in present-day terms) and $12 billion in 1966 ($ in present-day terms). In 2005, AT&T was acquired by " Baby Bell" and former subsidiary SBC Communications for more than $16 billion ($ in present-day terms). SBC then changed its name to AT&T Inc., with AT&T Corporation continuing to exist as a long-distance calling subsidiary until its dissolution on May 1, 2024. History Origins ...

Northwestel
Northwestel Inc. (stylized as NorthwesTel) is a Canadian telecommunications company that is the incumbent local exchange carrier (ILEC) and long-distance carrier in the territories of Yukon, the Northwest Territories, Nunavut, and part of northern British Columbia and northern Alberta. Originally established in 1979 by the Canadian National Railway from CN's northern telecommunications assets, it has been owned by BCE Inc. (formerly Bell Canada Enterprises) since 1988. Origins Until World War II The earliest telephone service in Northwestel's present-day operating territory was in Dawson City, established in 1899 just after the peak of the Klondike Gold Rush. However, that system was not linked into the North American phone network until the 1960s. Communications with the outside required the use of radio or radio telegraphy and did not connect with telephone lines. The independent company, Yukon Telephone Syndicate, was purchased by CN Telegraph (CNT) from Northern Light Power ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
