A telephone company (or telco) provides telecommunications Telecommunication is the assisted transmission over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags or heliograph. In modern times, telecommunication typically involves the use of electronic devices such as the telephone, television, radio or computer. Early services such as telephony In telecommunication, telephony encompasses the general use of equipment to provide voice communication over distances, specifically by connecting telephones to each other and data communications Computer networking is the engineering discipline concerned with communication between computer systems or devices. Networking, routers, routing protocols, and networking over the public Internet have their specifications defined in documents called RFCs. Computer networking is sometimes considered a sub-discipline of telecommunications, computer. Most of the largest telcos, whatever their origins, are or were at one time nationalized or state-regulated monopolies In economics, a monopoly exists when a specific individual or an enterprise has sufficient control over a particular product or service to determine significantly the terms on which other individuals shall have access to it.[clarification needed] Monopolies are thus characterized by a lack of economic competition for the good or service that they. These monopolies are often referred to, primarily in Europe, as PTTs.
Telcos are also known as common carriers A common carrier is a business that transports people, goods, or services and offers its services to the general public under license or authority provided by a regulatory body. A common carrier holds itself out to provide service to the general public without discrimination for the "public convenience and necessity". A common carrier, and in the United States The United States of America is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its 48 contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south as local exchange carriers In the United States, wireline telephone companies are divided into two large categories: long distance and local (local exchange carrier, or LECs). This structure is a result of 1984 divestiture of then regulated monopoly carrier American Telephone & Telegraph. Local telephone companies at the time of the divestiture are also known as. With the advent of cellular telephony Most current mobile phones connect to a cellular network of base stations , which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones), telcos now include wireless carriers A mobile network operator , also known as mobile phone operator (or simply mobile operator or mobo ),carrier service provider (CSP), wireless service provider, wireless carrier, mobile phone operator, or cellular company, is a telephone company that provides services for mobile phone subscribers, or network operators.
Most telcos now also function as internet service providers An Internet service provider is a company that offers its customers access to the Internet. The ISP connects to its customers using a data transmission technology appropriate for delivering Internet Protocol datagrams, such as dial-up, DSL, cable modem, wireless or dedicated high-speed interconnects (ISPs), and the distinction between telco and ISP may disappear completely over time, as the current trend for supplier convergence Supplier convergence is a term used to describe the ongoing trend of companies offering a combination of services or products that were previously supplied by separate companies. It is not to be confused with product convergence, where one product combines and replaces several others; rather, supplier convergence happens primarily through mergers in the industry continues.

This is distinguished from a mobile cellular line, where the medium used is the airwaves. Landlines usually cost less than cellular lines and provide better voice quality, and are used when there is no need for mobility with cell phones A mobile phone or mobile is a long-range, electronic device used for mobile telecommunications (mobile telephony, text messaging or data transmission) over a cellular network of specialized base stations known as cell sites. In addition to the standard voice function, current mobile phones may support many additional services, and accessories,.

Q. causing interference, what should be done amicably i was considering something to sheild or ground the unwanted frequencies, is that possible.
Asked by Naveen S - Fri Jun 6 00:24:16 2008 - - 2 Answers - 0 Comments
A. normal telco and ip wiring is twisted pair, made that way so that the leakage current field is cancelled. TV coax has a braid covering that acts as a perfect shield for the interior wire. Interference is a truly rare occurance. because telephone must pass DC current, a faulty connector on that line would cause it to not work at all and therefore could not cause interference. My guess is the Cable TV has a faulty connector at the trunk line, which would be easy for them to fix. I am assuming that you have not made any creative cable TV connections yourself.
