About Bell System
Bell System Detailed Bell (1847-1922) is the inventor of the telephone, so many telecom companies in the world have form a large number of Bell. Bell himself founded Bell Telecommunications, and monopolized the US telecommunications business for a hundred years, Bell system took AT & T as a parent company, and many subsidiaries and research institutes. On the other hand, there are other Bell companies in the United States, Europe, Asia, such as Bell Communication Research Institute, Bellcore; Bellcore; Bell Telephone Equipment manufacturing company, BTM; Shanghai Bell Telephone Equipment Manufacturing companies, etc.) Although named "Bell" is not a Bell system. Bell obtained the telephone patent in 1876, and the second year, Bell Telephone is founded in 1880, and the Bell system was established in 1880. To develop long-distance calls, Bell established the US Telephone Telegraph (AT & T) in 1885, which continuously developed. In 1899, it became a Bell system with AT & T for the mother, including a manufacturing equipment equipment, a Bell Institute, who engages in scientific research. Bell Operations in the operation of the telephone business. After Bell's telephone patent expires, thousands of independent telephone companies have emerged. However, because the Bell system has strong scientific research and production power, it has a huge telecommunications network, so long-term monopoly of 80% of the US-city telephone business and 90% long-distance business, and monopolizes the US telecommunications equipment market. Since the Bell system has caused the long-term monopoly of the US telecommunications, the US Department of Justice has repeatedly sued the "anti-Torres" to the court, the court was sentenced to the Bell system in 1982. On January 1, 1984, Bell system officially declared disintegration, and the AT & T of the disintegration may not use "Bell" as the name, and the original blue bell-shaped emblem is not allowed to use 22 Bell Operations Company (BOC) belonging to it. Master AT & T Ideated, combined into seven regional holding companies (RHC), reorganized AT & T, AT & T, may not operate the city's telephone business (1996 US Telecom Act has further open telecommunications market, allowing long-distance calls, CATV, Power and other companies to operate Local telecommunications business continues to retain long-distance telephone traffic (but with other long-distance companies such as MCI, Sprint) to enter the net to compete with fair competition). In 1988 and 1995, AT & T was again reorganized, and its network system, the technical system (including the former WIP) and other companies from AT & T, and combined with the Bell Telephone Research Institute. After the Bell system disintegrates, the recombinant RHCS and the BOCS can continue to use Bell as the company's name, and some people call "small Bell" (although some of some of the company's name is not Bell). The BOCS is separated from the AT & T to make up the RHCS. The Bell Communication Institute (Bellcore) has also been established with the Bell Institute (AT & T Bell Laboraries), but because of its name, "Bell" is, it is easy to be mistaken for the same research institute. The US International Telephone Telecommunications Company (ITT) belongs to another consortium and has divided into AT & T in business. AT & T operates a US domestic telecommunications business, while ITT operates in foreign countries.
