The People's Republic of China possesses a diversified communications system that links all parts of the country by Internet, telephone, telegraph, radio, and television. The country is served by an extensive system of automatic telephone exchanges connected by modern networks of fiber-optic cable, coaxial cable, microwave radio relay, and a domestic satellite system; cellular telephone service is widely available, expanding rapidly, and includes roaming service to foreign countries. Fiber to the x infrastructure has been expanded rapidly in recent years.
At the most basic level, Personal Communications Service (PCS) describes a set of communications capabilities which allows some combination of terminal mobility, personal mobility, and service profile management. More specifically, PCS refers to any of several types of wireless voice or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced cellular mobile or paging services. In addition, PCS can also be used to provide other wireless communications services, including services which allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other fixed havelocations. Described in more commercial terms, PCS is a generation of wireless-phone technology that combines a range of features and services surpassing those available in analog- and digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.
Communications security is the discipline of preventing unauthorized interceptors from accessing telecommunications in an intelligible form, while still delivering content to the intended recipients.
In telecommunication, the term outside plant has the following meanings:
In telecommunications a link is a communication channel that connects two or more devices. This link may be an actual physical link or it may be a logical link that uses one or more physical links or shares a physical link with other telecommunications links.
MIL-STD-188 is a series of U.S. military standards relating to telecommunications.
A colocation centre or "carrier hotel", is a type of data centre where equipment, space, and bandwidth are available for rental to retail customers. Colocation facilities provide space, power, cooling, and physical security for the server, storage, and networking equipment of other firms and also connect them to a variety of telecommunications and network service providers with a minimum of cost and complexity.
A competitive local exchange carrier (CLEC), in the United States and Canada, is a telecommunications provider company competing with other, already established carriers.

In telecommunications, structured cabling is building or campus cabling infrastructure that consists of a number of standardized smaller elements called subsystems.
In telecommunications, interconnection is the physical linking of a carrier's network with equipment or facilities not belonging to that network. The term may refer to a connection between a carrier's facilities and the equipment belonging to its customer, or to a connection between two carriers.
The Center for Information Technology (CIT) is one of the 27 institutes and centers that compose the National Institutes of Health (NIH), an agency of the U.S. Department of Health and Human Services (HHS), a cabinet-level department of the Executive Branch of the United States Federal Government. Originating in 1954 as a central processing facility in the NIH Office of the Director, the Division of Computer Research and Technology was established in 1964, merging in 1998 with the NIH Office of the CIO and the NIH Office of Research Services Telecommunications Branch to form a new organization, the CIT.
Telecommunications engineering is an engineering discipline centered on electrical and computer engineering which seeks to support and enhance telecommunication systems. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching systems, and other plain old telephone service facilities, optical fiber cabling, IP networks, and microwave transmission systems. Telecommunication engineering also overlaps with broadcast engineering.
Here is a list of Electronic Industries Alliance (EIA) Standards. The EIA ceased operations on February 11, 2011, but the former sectors continue to serve the constituencies of EIA. EIA designated ECA to continue to develop standards for interconnect, passive and electro-mechanical (IP&E) electronic components under the ANSI-designation of EIA standards. All other electronic components standards are managed by their respective sectors. ECA is expected to merge with the National Electronic Distributors Association (NEDA) to form the Electronic Components Industry Association (ECIA). However, the EIA standards brand will continue for IP&E standards within ECIA. As currently authorized, any ANSI standard designated at ANSI EIA-xxx is developed and/or managed by ECA .
In computing, network virtualization or network virtualisation is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, a virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization.
The Bell System was the system of companies, led by the Bell Telephone Company and later by AT&T, which provided telephone services to much of the United States and Canada from 1877 to 1984, at various times as a monopoly. On December 31, 1983, the system was divided into independent companies by a U.S. Justice Department mandate.
Based in Hollywood, Florida, HEICO Corporation (NYSE:HEI.A) (NYSE:HEI) is an aerospace and electronics company that focuses on niche markets.
ANSI/TIA-568 is a set of telecommunications standards from the Telecommunications Industry Association (TIA). The standards address commercial building cabling for telecommunications products and services.
Common Language Information Services encompasses several products that are in general use by the global telecommunications industry through license agreements. Common Language products combine numerics and mnemonics to establish naming conventions that telecommunication companies use to exchange critical information via Operations Support Systems and other interface mechanisms.
