Managed Object
In telecommunication, the term managed object has the following meanings: 1. In a network, an abstract representation of network resources that are managed. With "representation", we mean not only the actual device that is managed, but also the device driver, that communicates with the device. An example of a printer as a managed object is the window that shows information about the printer, such as the location, printer status, printing progress, paper choice, and printing margins. The database, where all managed objects are stored, is called Management Information Base. In contrast with a CI, a managed object is "dynamic" and communicates with other network resources that are managed. ''Note:'' A managed object may represent a physical entity, a network service, or an abstraction of a resource that exists independently of its use in management. 2. In telecommunications management, a resource within the telecommunications environment that may be managed through the use of op ...

Telecommunication
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 ...

Telecommunications Network
A telecommunications network is a group of nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals. Multiple nodes may cooperate to pass the message from an originating node to the destination node, via multiple network hops. For this routing function, each node in the network is assigned a network address for identification and locating it on the network. The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, and the wireless radio networks of cell phone telecommunication providers. Network structure In general, every telecommunications network conceptually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Device Driver
In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used. A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device (drives it). Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface. Purpose The main purpose of device drivers is to provide abstraction by acting as a translator be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Window (computing)
In computing, a window is a graphical control element. It consists of a visual area containing some of the graphical user interface of the program it belongs to and is framed by a window decoration. It usually has a rectangular shape that can overlap with the area of other windows. It displays the ''output'' of and may allow ''input'' to one or more processes. Windows are primarily associated with graphical displays, where they can be manipulated with a pointer by employing some kind of pointing device. Text-only displays can also support windowing, as a way to maintain multiple independent display areas, such as multiple buffers in Emacs. Text windows are usually controlled by keyboard, though some also respond to the mouse. A graphical user interface (GUI) using windows as one of its main "metaphors" is called a windowing system, whose main components are the display server and the window manager. History The idea was developed at the Stanford Research Institute (led by D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Management Information Base
A management information base (MIB) is a database used for managing the entities in a communication network. Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in OSI/ISO Network management model. While intended to refer to the complete collection of management information available on an entity, it is often used to refer to a particular subset, more correctly referred to as MIB-module. Objects in the MIB are defined using a subset of Abstract Syntax Notation One (ASN.1) called "Structure of Management Information Version 2 (SMIv2)" . The software that performs the parsing is a MIB compiler. The database is hierarchical (tree-structured) and each entry is addressed through an object identifier (OID). Internet documentation RFCs discuss MIBs, notably , "Structure and Identification of Management Information for TCP/IP based internets", and its two companions, , "Management Information Base for N ...

Carrier Interferometry
Carrier Interferometry (CI) is a spread spectrum scheme designed to be used in an Orthogonal Frequency-Division Multiplexing (OFDM) communication system for multiplexing and multiple access, enabling the system to support multiple users at the same time over the same frequency band. Like MC-CDMA, CI-OFDM spreads each data symbol in the frequency domain. That is, each data symbol is carried over multiple OFDM subcarriers. But unlike MC-CDMA, which uses binary-phase Hadamard codes (code values of 0 or 180 degrees) or binary pseudonoise, CI codes are complex-valued orthogonal codes. In the simplest case, CI code values are coefficients of a discrete Fourier transform (DFT) matrix. Each row or column of the DFT matrix provides an orthogonal CI spreading code which spreads a data symbol. Spreading is achieved by multiplying a vector of data symbols by the DFT matrix to produce a vector of coded data symbols, then each coded data symbol is mapped to an OFDM subcarrier via an input bin o ...

Business Operations
Business operations is the ''harvesting'' of value from assets owned by a business. Assets can be either ''physical'' or '' intangible''. An example of value derived from a physical asset, like a building, is rent. An example of value derived from an intangible asset, like an idea, is a royalty. The effort involved in "harvesting" this value is what constitutes business operations cycles. Overview Business operations encompass three fundamental management imperatives that collectively aim to maximize value harvested from business assets (this has often been referred to as "sweating the assets"): # Generate recurring income # Increase the value of the business assets # Secure the income and value of the business The three imperatives are interdependent. The following basic tenets illustrate this interdependency: * ''The more recurring income an asset generates, the more valuable it becomes''. **For example, the products that sell at the highest volumes and prices are usually c ...

Business Administration
Business administration, also known as business management, is the administration of a commercial enterprise. It includes all aspects of overseeing and supervising the business operations of an organization. From the point of view of management and leadership, it also covers fields that include office building administration, accounting, finance, designing, development, quality assurance, data analysis, sales, project management, information-technology management, research and development, and marketing. Overview The administration of a business includes the performance or management of business operations and decision-making, as well as the efficient organization of people and other resources to direct activities towards common goals and objectives. In general, "administration" refers to the broader management function, including the associated finance, personnel and MIS services. Administration can refer to the bureaucratic or operational performance of routine of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Repair And Maintenance
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure. Definitions Maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions:Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or restore a fun ...

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. ...

OAMP
Operations, administration and management or operations, administration and maintenance (OA&M or OAM) are the processes, activities, tools, and standards involved with operating, administering, managing and maintaining any system. This commonly applies to telecommunication, computer networks, and computer hardware. In particular, Ethernet operations, administration and maintenance (EOAM) is the protocol for installing, monitoring and troubleshooting Ethernet metropolitan area network (MANs) and Ethernet WANs. It relies on a new, optional sublayer in the data link layer of the OSI model. The OAM features covered by this protocol are discovery, link monitoring, remote fault detection, remote loopback Standards * Fault management and performance monitoring ( ITU-T Y.1731) - Defines performance monitoring measurements such as frame loss ratio, frame delay and frame delay variation to assist with SLA assurance and capacity planning. For fault management the standard defines contin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
