Telecommunications Company
A telephone company, also known as a telco, telephone service provider, or telecommunications operator, is a kind of communications service provider (CSP), more precisely a telecommunications service provider (TSP), that provides telecommunications services such as telephony and data communications access. Many telephone companies were at one time government agencies or privately owned but state-regulated monopolies. The government agencies are often referred to, primarily in Europe, as PTTs (postal, telegraph and telephone services). Telephone companies are common carriers, and in the United States are also called local exchange carriers. With the advent of mobile telephony, telephone companies now include wireless carriers, or mobile network operators. Most telephone companies now also function as internet service providers (ISPs), and the distinction between a telephone company and an ISP may disappear completely over time, as the current trend for supplier convergence in ...

Bell Edison Telephone Building
A bell is a directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that when struck vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell (jingle bell). Bells are usually cast from bell metal (a type of bronze) for its resonant properties, but can also be made from other hard materials. This depends on the function. Some small bells such as ornamental bells or cowbells can be made from cast or pressed metal, glass or ceramic, but large bells such as a church, clock and tower bells are normally cast from bell metal. Bells intended to be heard over a wide area can range from a single bell hung in a turret or bell-gable, to a musical ensemble such as an English ring of bells, a carillon or a Russian zvon which are tuned to a common scale and inst ...

Kingsbury Commitment
The Kingsbury Commitment is a 1913 out-of-court settlement of the United States government's antitrust challenge against the American Telephone and Telegraph Company (AT&T) for AT&T's then-growing vertical monopoly in the telephone industry. In return for the government's agreement not to pursue its case against the company as a monopolist, AT&T agreed to divest the controlling interest it had acquired in the Western Union telegraph company, and to allow non-competing independent telephone companies to interconnect with the AT&T long-distance network. History In 1907, Theodore N. Vail became president of AT&T for the second time. Immediately, he steered the company into a new direction, in terms of vision, company organization, and technology. He envisioned telephone service as a public utility, and the future of the American telephone industry as a unified system of companies under the lead of his company. This required technical standards understood and accepted by all players in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
