Introduction Part I contains information about this document, which provides the written record of the Massachusetts Institute of Technology Business Continuity Plan. Introduction to This Document Planning for the business continuity of MIT in the aftermath of a disaster is a complex task.
What little remained was largely outdated and rudimentary and limited to the eastern coastal cities, the Nanjing - Shanghai region, and a few interior cities. In the s existing facilities were repaired, and, with Soviet assistance telecommunications business plan, considerable progress was made toward establishing a long-distance telephone wire network connecting Beijing to provincial-level capitals.
Communications in China were established rapidly in the early s. By the principal telecommunications network centered on Beijingand links to all large cities had finally been established.
Work quickly got under way to repair, renovate and expand the system, and from telecommunications routes were extended more rapidly.
To increase the efficiency of the communications systemthe same lines were used for both telegraphic and telephone service, while Teletype and television broadcasting services were also added.
In addition, conference telephone service was initiated, radio communications were improved, and the production of telecommunications equipment was accelerated.
Growth in telecommunications halted with the general economic collapse after the Great Leap Forward —60 but revived in the s after the telephone network was expanded and improved equipment was introduced, including imports of Western plants and equipment.
By telephone wire had been laid from Beijing to the capitals of all provincesautonomous regionsand large citieswhile in turn, provincial capitals and autonomous regions were connected to the administrative seats of the countiessmaller municipalities and larger market towns.
In the years immediately followingtelecommunications — by telegraph or telephone — mainly used wire ; by the s, however, radio telecommunications equipment were increasingly used and began to replace wire lines.
Microwave and satellite transmissions were soon introduced and have now become common. China launched its first television-broadcast satellite in In the first automatic speed Teletype was installed on the Beijing - Lhasa line.
By such machines had been installed in most of China's major cities. Radio-television service also was installed in major cities, and radio teleprinters became widely used. An important component of the Fourth Five-Year Plan —75 was a major development program for the telecommunications system.
The program allotted top priority to scarce electronics and construction resources and dramatically improved all aspects of China's telecommunications capabilities.
Microwave radio relay lines and buried cable lines were constructed to create a network of wideband carrier trunk lines, which covered the entire country.
China was linked to the international telecommunications network by the installation of communications satellite ground stations and the construction of coaxial cables linking Guangdong Province with Hong Kong and Macau.
Provincial-level units and municipalities rapidly expanded local telephone and wire broadcasting networks. Expansion and modernization of the telecommunications system continued throughout the lates and early s, giving particular emphasis to the production of radio and television sets and expanded broadcasting capabilities.
Marked improvements occurred by the mids with an influx of foreign technology and increased domestic production capabilities. International and long-distance telephone links by cable and satellite of high quality multiplied.
Telegraph, facsimile, and telex were all in use. International satellite ground stations in Beijing and Shanghai were built and a domestic satellite communication network was operational in Over radio stations existed by the mids, and transistorized radio receivers were common.
A vast wired broadcasting system included over 2, stations carrying radio transmissions into all rural units and many urban areas. The television system grew rapidly in s, with 90 television stations and 80 million sets by By China possessed a diversified telecommunications system that linked all parts of the country by telephone, telegraph, radio, and television.
None of the telecommunications forms were as prevalent or as advanced as those in modern Western countriesbut the system included some of the most sophisticated technology in the world and constituted a foundation for further development of a modern network.
Overall, China's telecommunications services improved enormously during the s, and, the pace of telecommunications growth and technology upgrading increased even more rapidly afterespecially as fiber-optic systems and digital technology were installed.
AfterChina's telecommunications services were enhanced further with the acquisition of Hong Kong 's highly advanced systems.
In the late s and early s, foreign investment in the country's telecommunications sector further encouraged growth. Notable has been the tremendous increase in Internet and cellular phone usage. China became the world leader in the early 21st century, in terms of number of cell phone subscribers.BlueIsland's featured product will be a userfriendly Internet website that provides free and fee-based services to meet the needs of its customers—advertising buyers and sellers.
