Network Element
In computer networks, a network element is a manageable logical entity uniting one or more physical devices. This allows distributed devices to be managed in a unified way using one management system. According to the Telecommunications Act of 1996, the term '''network element refers to a facility or to equipment used in the provision of a telecommunications service. This term also refers to features, functions, and capabilities that are provided by means of such facility or equipment. This includes items such as subscriber numbers, databases, signaling systems, and information that is sufficient for billing and collection. Alternatively, it's also included if it's used in the transmission, routing, or other provision of a telecommunications service. Background With development of distributed networks, network management had become an annoyance for administration staff. It was hard to manage each device separately even if they were of the same vendor. Configuration overhead as w ...

Computer Network
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications pro ...

Telecommunications Act Of 1996
The Telecommunications Act of 1996 is a United States federal law enacted by the 104th United States Congress on January 3, 1996, and signed into law on February 8, 1996, by President Bill Clinton. It primarily amended Chapter 5 of Title 47 of the United States Code, The act was the first significant overhaul of United States telecommunications law in more than sixty years, amending the Communications Act of 1934, and represented a major change in American telecommunication law, because it was the first time that the Internet was included in broadcasting and spectrum allotment.The Telecommunications Act of 1996. Title 3, sec. 301. Retrieved frofcc.gov (2011) The goal of the law was to "let anyone enter any communications business – to let any communications business compete in any market against any other." The legislation's primary goal was deregulation of the converging broadcasting and telecommunications markets. The law's regulatory policies have been criticized, includin ...

Provisioning
In telecommunication, provisioning involves the process of preparing and equipping a network to allow it to provide new services to its users. In National Security/Emergency Preparedness telecommunications services, ''"provisioning"'' equates to ''"initiation"'' and includes altering the state of an existing priority service or capability. The concept of network provisioning or service mediation, mostly used in the telecommunication industry, refers to the provisioning of the customer's services to the network elements, which are various equipment connected in that network communication system. Generally in telephony provisioning this is accomplished with network management database table mappings. It requires the existence of networking equipment and depends on network planning and design. In a modern signal infrastructure employing information technology (IT) at all levels, there is no possible distinction between telecommunications services and "higher level" infrastructure. ...

Telephone Exchange
A telephone exchange, telephone switch, or central office is a telecommunications system used in the public switched telephone network (PSTN) or in large enterprises. It interconnects telephone subscriber lines or virtual circuits of digital systems to establish telephone calls between subscribers. In historical perspective, telecommunication terms have been used with different semantics over time. The term ''telephone exchange'' is often used synonymously with ''central office'', a Bell System term. Often, a ''central office'' is defined as a building used to house the inside plant equipment of potentially several telephone exchanges, each serving a certain geographical area. Such an area has also been referred to as the exchange or exchange area. In North America, a central office location may also be identified as a ''wire center'', designating a facility to which a telephone is connected and obtains dial tone. For business and billing purposes, telecommunication carriers defi ...

Local Telephone Service
Local telephone service is the provision of telecommunications networks and services within a limited geographic region. Traditionally, local telephone service was provided by small companies based in given cities and towns as opposed to larger, national or international companies. Telephone calls outside of the local area provided for by these companies were patched through long-distance networks that were, until de-regulation, operation mainly by AT&T. Some providers of local services were regional Bell operating companies, but not all local telephone companies were a regional Bell operating company or tied to one at the local level, especially after de-regulation of 1996. After de-regulation, these regional Bell operating companies continued providing the same technical services despite being under a different type of corporate structure. Many communities in the United States had local telephone companies and in rural areas, up until around the early 1980s (perhaps later in s ...

Computer Cluster
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability. Computer clusters emerged as a result of convergence of a number of computing trends including t ...

Datacenter
A data center (American English) or data centre (British English)See spelling differences. is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a small town. History Data centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center.Old large computer rooms that housed machines like the U.S. Army's ENIAC, which were developed pre-1960 (1945), were now referred to as "data centers". Early computer systems, complex to operate and ma ...

Telecommunications Management Network
The Telecommunications Management Network is a protocol model defined by ITU-T for managing open systems in a communications network. It is part of the ITU-T Recommendation series M.3000 and is based on the OSI management specifications in ITU-T Recommendation series X.700. TMN provides a framework for achieving interconnectivity and communication across heterogeneous operations system and telecommunication networks. To achieve this, TMN defines a set of ''interface points'' for elements which perform the actual communications processing (such as a call processing switch) to be accessed by elements, such as management workstations, to monitor and control them. The standard interface allows elements from different manufacturers to be incorporated into a network under a single management control. For communication between Operations Systems and NEs (Network Elements), it uses the Common management information protocol (CMIP) or Mediation devices when it uses Q3 interface. The TM ...

Element Management System
An element management system (EMS) consists of systems and applications for managing network elements (NE) on the network element-management layer (NEL) of the Telecommunications Management Network (TMN) model. As recommended by ITU-T, the element management system's key functionality is divided into five key areas - fault, configuration, accounting, performance and security (FCAPS). Portions of each of the FCAPS functionality fit into the TMN models. Northbound, the EMS interfaces to network management systems and or service management systems depending on the deployment scenario. Southbound, the EMS talks to the devices. An element management system manages one or more of a specific type of telecommunications network element. Typically, the EMS manages the functions and capabilities within each NE but does not manage the traffic between different NEs in the network. To support management of the traffic between itself and other NEs, the EMS communicates upward to higher-level ne ...

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 t ...
