Competitive Local Exchange Carrier
A competitive local exchange carrier (CLEC) is a North American telecommunications provider classification that emerged based on the competition model of the Telecommunications Act of 1996 in the United States. The act required the previously established incumbent local exchange carrier (ILEC) in each local market to provide infrastructure hosting and services to CLECs to enable competition with the ILEC. Background Local exchange carriers (LECs) are characterized as incumbent (ILECs) or competitive (CLECs). The ILECs are usually the original, monopoly LEC in a given area, and receive different regulatory treatment from the newer CLECs. A data local exchange carrier (DLEC) is a CLEC specializing in DSL services by leasing lines from the ILEC and reselling them to Internet service providers (ISPs). History CLECs evolved from the competitive access providers (CAPs) that began to offer private line and special access services in competition with the ILECs beginning in 1985. The CA ...

Telecommunications
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent Session (computer science), communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics.

Digital Signal 1
Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. DS1 is the primary digital telephone standard used in the United States, Canada and Japan and is able to transmit up to 24 multiplexed voice and data calls over telephone lines. E-carrier is used in place of T-carrier outside the United States, Canada, Japan, and South Korea. DS1 is the logical bit pattern used over a physical T1 line; in practice, the terms ''DS1'' and ''T1'' are often used interchangeably. Overview T1 refers to the primary digital telephone carrier system used in North America. T1 is one line type of the PCM T-carrier hierarchy. T1 describes the cabling, signal type, and signal regeneration requirements of the carrier system. The signal transmitted on a T1 line, referred to as the DS1 signal, consists of serial bits transmitted at the rate of 1.544 Mbit/s. The type of line code used is called Alternate Mark Inversion (AMI). Digital Signal Designation is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberalization
Liberalization or liberalisation (British English) is a broad term that refers to the practice of making laws, systems, or opinions less severe, usually in the sense of eliminating certain government regulations or restrictions. The term is used most often in relation to economics, where it refers to economic liberalization, the removal or reduction of restrictions placed upon (a particular sphere of) economic activity. However, liberalization can also be used as a synonym for decriminalization or legalization (the act of making something legal after it used to be illegal), for example when describing drug liberalization. In economy and trade Economic liberalization refers to the reduction or elimination of government regulations or restrictions on private business and trade. It is usually promoted by advocates of free markets and free trade, whose ideology is also called economic liberalism. Economic liberalization also often involves reductions of taxes, social security, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Telecom Association
The United States Telecom Association (USTelecom) is an organization that represents telecommunications-related businesses based in the United States. As a trade association, it represent the converged interests of the country's telecommunications industry. Member companies represent a diverse set of communications-related businesses, including those that provide wireless, Internet, cable television, long distance, local exchange, and voice services. Members include large publicly traded communications carriers as well as small telephone cooperatives that serve only a few hundred customers in urban and rural areas. The organization was founded as the Independent Telephone Association of America in 1897, and represented the telecommunication industry of North America that was not affiliated with the Bell System led by the American Telephone and Telegraph Company (AT&T). History The United States Telecom Association (USTelecom) was founded in Chicago, Illinois, on May 17, 1897, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Loop
In telephony, the local loop (also referred to as the local tail, subscriber line, or in the aggregate as the last mile) is the physical link or circuit that connects from the demarcation point of the customer premises to the edge of the common carrier or telecommunications service provider's network. At the edge of the carrier access network in a traditional public telephone network, the local loop terminates in a circuit switch housed in an incumbent local exchange carrier or telephone exchange. Infrastructure Traditionally, the local loop was an electrical circuit in the form of a single pair of conductors from the telephone on the customer's premises to the local telephone exchange. Single-wire earth return lines had been used in some countries until the introduction of electric tramways from the 1900s made them unusable. Historically the first section was often an aerial open-wire line, with several conductors attached to porcelain insulators on cross-arms on "te ...

Wholesale
Wholesaling or distributing is the sale of goods or merchandise to retailers; to industrial, commercial, institutional or other professional business users; or to other wholesalers (wholesale businesses) and related subordinated services. In general, it is the sale of goods in bulk to anyone, either a person or an organization, other than the end consumer of that merchandise. Wholesaling involves purchasing goods in bulk, usually directly from the manufacturer or source, at a discounted rate. Retailers then sell these goods to end consumers at a higher price, generating a profit. According to the United Nations Statistics Division, ''wholesale'' is the resale of new and used goods to retailers, to industrial, commercial, institutional or professional users, or to other wholesalers, or involves acting as an agent or broker in buying merchandise for, or selling merchandise to, such persons or companies. Wholesalers frequently physically assemble, sort, and grade goods in la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lease
A lease is a contractual arrangement calling for the user (referred to as the ''lessee'') to pay the owner (referred to as the ''lessor'') for the use of an asset. Property, buildings and vehicles are common assets that are leased. Industrial or business equipment are also leased. In essence, a lease agreement is a contract between two parties: the lessor and the lessee. The lessor is the legal owner of the asset, while the lessee obtains the right to use the asset in return for regular rental payments. The lessee also agrees to abide by various conditions regarding their use of the property or equipment. For example, a person leasing a car may agree to the condition that the car will only be used for personal use. The term rental agreement can refer to two kinds of leases: * A lease in which the asset is tangible property. Here, the user '' rents'' the asset (e.g. land or goods) ''let out'' or ''rented out'' by the owner (the verb ''to lease'' is less precise because it c ...

Void (law)
In law, void means of no legal effect. An action, document, or transaction which is void is of no legal effect whatsoever: an absolute nullity—the law treats it as if it had never existed or happened. The term void ''ab initio'', which means "to be treated as invalid from the outset", comes from adding the Latin phrase ''ab initio'' (from the beginning) as a qualifier. For example, in many jurisdictions where a person signs a contract under duress, that contract is treated as being void ''ab initio''. The frequent combination "null and void" is a legal doublet. The term is frequently used in contradistinction to the term "voidable" and " unenforceable". Definitions '' Black's Law Dictionary'' defines 'void' as " ll; ineffectual; nugatory; having no legal force or binding effect...." In the case of a contract, this means there is no legal obligation, therefore there can be no breach of contract since the contract is null, but there may be an implied contract A quasi-contr ...

Appeal
In law, an appeal is the process in which Legal case, cases are reviewed by a higher authority, where parties request a formal change to an official decision. Appeals function both as a process for error correction as well as a process of clarifying and interpreting law. Although appellate courts have existed for thousands of years, common law countries did not incorporate an affirmative right to appeal into their jurisprudence until the 19th century. Terminology American English and British English have diverged significantly on the topic of appellate terminology. American cases go up "on appeal" and one "appeals from" (Intransitive verb, intransitive) or "appeals" (Transitive verb, transitive) an order, award, judgment, or conviction, while decisions of British courts are said to be "under appeal" and one "appeals against" a judgment. An American court disposes of an appeal with words like "judgment affirmed" (the appeal is without merit) or "judgment reversed" (the app ...

Coaxial Cable
Coaxial cable, or coax (pronounced ), is a type of electrical cable consisting of an inner Electrical conductor, conductor surrounded by a concentric conducting Electromagnetic shielding, shield, with the two separated by a dielectric (Insulator (electricity), insulating material); many coaxial cables also have a protective outer sheath or jacket. The term ''coaxial'' refers to the inner conductor and the outer shield sharing a geometric axis. Coaxial cable is a type of transmission line, used to carry high-frequency Signal, electrical signals with low losses. It is used in such applications as telephone trunk lines, Internet access, broadband internet networking cables, high-speed computer bus (computing), data buses, cable television signals, and connecting Transmitter, radio transmitters and Radio receiver, receivers to their Antenna (radio), antennas. It differs from other shielded cables because the dimensions of the cable and connectors are controlled to give a precise, ...

Unbundled Network Element
Unbundled network elements (UNEs) are a requirement mandated by the United States Telecommunications Act of 1996. They are the parts of the telecommunications network that the incumbent local exchange carriers (ILECs) are required to offer on an unbundled basis. Together, these parts make up a local loop that connects to a digital subscriber line access multiplexer (DSLAM), a voice switch or both. The loop allows non-facilities-based telecommunications providers to deliver service without having to lay network infrastructure such as copper wire, optical fiber, and coaxial cable. UNE-Platform A UNE-Platform (or UNE-P) is a combination of UNEs that allow end-to-end service delivery without any facilities. Despite not involving any CLEC facilities, a UNE-P still requires facilities-based certification from the Public Utilities Commission to deliver services. Availability In Telecommunications Act of 1996 sections 251(c)(3), incumbent local exchange carriers (LECs) are required to ...

Regional Bell Operating Companies
A Regional Bell Operating Company (RBOC) was a corporate entity created as result of the antitrust lawsuit by the United States Department of Justice against the Western Electric Company and American Telephone and Telegraph Company (AT&T) in 1949 and a suit in 1974 against AT&T ('' United States v. AT&T''). The suits were settled in the Modification of Final Judgment in August 1982. AT&T agreed to divest its local exchange service operating companies, effective January 1, 1984. The group of local operating companies were split into seven independent Regional Bell Operating Companies, which became known as the Baby Bells. Three companies still exist that have an RBOC as a predecessor: AT&T, Verizon, and Lumen Technologies (formerly CenturyTel and CenturyLink). Some other companies are holding onto smaller segments of the companies. Baby Bells A "Baby Bell" is a local telephone company in the United States that was in existence at the time of the breakup of AT&T into the resulti ...
