TW Telecom
TW Telecom (styled tw telecom), was a business telecommunications company headquartered in Littleton, Colorado, United States. The company provided business voice services, transport, Internet, data services and wholesale fiber capacity. It was an early leader in the deployment of Ethernet for metropolitan areas, dubbed Metro Ethernet. The company was acquired by Level 3 Communications on November 1, 2014. Exactly three years later, CenturyLink (now Lumen Technologies) acquired Level 3 Communications on November 1, 2017. History Founded in 1993 as Time Warner Communications, the company was a joint venture between US West and Time Warner Cable, a division of Time Warner Entertainment, to deliver telephone services over a hybrid fiber and coaxial network. The company was successful in their efforts, but at the time the cost to build fiber directly to consumer's homes proved too expensive to be profitable. In the mid-1990s the company evolved into a "carriers carrier" selling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Warner Cable
Time Warner Cable, Inc. (TWC) was an American cable television company. Before it was acquired by Charter Communications on May 18, 2016, it was ranked the second largest cable company in the United States by revenue behind only Comcast, operating in 29 states. Its corporate headquarters were located in the Time Warner Center in Midtown Manhattan, New York City, with other corporate offices in Stamford, Connecticut; Charlotte, North Carolina; and Herndon, Virginia. It was controlled by Warner Communications, then by Time Warner (later known as WarnerMedia and now Warner Bros. Discovery). That company spun off the cable operations in March 2009 as part of a larger restructuring. From 2009 to 2016, Time Warner Cable was an entirely independent company, continuing to use the Time Warner name under license from its former parent company (including the " Road Runner" name for its Internet service, now Spectrum Internet). In 2014, the company was the subject of a proposed purchase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Content Delivery Networks
A content delivery network, or content distribution network (CDN), is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and performance by distributing the service spatially relative to end users. CDNs came into existence in the late 1990s as a means for alleviating the performance bottlenecks of the Internet as the Internet was starting to become a mission-critical medium for people and enterprises. Since then, CDNs have grown to serve a large portion of the Internet content today, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social media sites. CDNs are a layer in the internet ecosystem. Content owners such as media companies and e-commerce vendors pay CDN operators to deliver their content to their end users. In turn, a CDN pays Internet service providers ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunications Companies Of The United States
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

Metro Ethernet
A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or the Internet. Businesses can also use metropolitan-area Ethernet to connect their own offices to each other. An Ethernet interface is typically more economical than a synchronous digital hierarchy (SONET/SDH) or plesiochronous digital hierarchy (PDH) interface of the same bandwidth. Another distinct advantage of an Ethernet-based access network is that it can be easily connected to the customer network, due to the prevalent use of Ethernet in corporate and residential networks. A typical service provider's network is a collection of switches and routers connected through optical fiber. The topology could be a ring, hub-and-spoke (star), or full or partial mesh. The network will also have a hierarchy: core, distribution (aggregation), and access. The core in most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dark Fiber
A dark fibre or unlit fibre is an unused optical fibre, available for use in fibre-optic communication. Dark fibre may be leased from a network service provider. Dark fibre originally referred to the potential network capacity of telecommunication infrastructure. Because the marginal cost of installing additional fibre optic cables is very low once a trench has been dug or conduit laid, a great excess of fibre was installed in the US during the telecom boom of the late 1990s and early 2000s. This excess capacity was later referred to as ''dark fibre'' following the dot-com crash of the early 2000s that briefly reduced demand for high-speed data transmission. These unused fibre optic cables later created a new market for unique private services that could not be accommodated on ''lit'' fibre cables (i.e., cables used in traditional long-distance communication). Motivations Much of the cost of installing cables is in the civil engineering work required. This includes planning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
