An access network is a type of telecommunications network which connects subscribers to their immediate service provider.
Authentication (from authentikos, "real, genuine", from αὐθέντης authentes, "author") is the act of confirming the truth of an attribute of a single piece of data claimed true by an entity.
Automatic message accounting (AMA) provides detailed accounting for telephone calls.
In a hierarchical telecommunications network the backhaul portion of the network comprises the intermediate links between the core network, or backbone network, and the small subnetworks at the "edge" of the entire hierarchical network.
A network bridge is a computer networking device that creates a single aggregate network from multiple communication networks or network segments.
In telephony, call control refers to the software within a telephone switch that supplies its central function.
A call transfer is a telecommunications mechanism that enables a user to relocate an existing telephone call to another phone or attendant console, using a transfer button or a switchhook flash and dialing the required location.
Call waiting is a telecommunication service offered by a telephone service provider to a subscriber by which the subscriber may suspend a telephone call already in progress to accept a second call.
The called party (in some contexts called the "B-Number") is a person who (or device that) answers a telephone call.
A computer network, or data network, is a digital telecommunications network which allows nodes to share resources.
Customer-premises equipment or customer-provided equipment (CPE) is any terminal and associated equipment located at a subscriber's premises and connected with a carrier's telecommunication circuit at the demarcation point ("demarc").
Fault tolerance is the property that enables a system to continue operating properly in the event of the failure (or one or more faults within) some of its components.
A gateway is the piece of networking hardware used in telecommunications via communications networks that allows data to flow from one discrete network to another.
Interconnectivity refers to the state or quality of being connected together, or to the potential to connect in an easy and effective way.
Interexchange carrier (IXC) is a U.S. legal and regulatory term for a telecommunication company, commonly called a long-distance telephone company.
The Internet backbone might be defined by the principal data routes between large, strategically interconnected computer networks and core routers on the Internet.
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.
Local number portability (LNP) for fixed lines, and full mobile number portability (FMNP) for mobile phone lines, refers to the ability of a "customer of record" of an existing fixed-line or mobile telephone number assigned by a local exchange carrier (LEC) to reassign the number to another carrier ("Service Provider Portability"), move it to another location ("Geographic Portability"), or change the type of service ("Service Portability").
A mesh network is a local network topology in which the infrastructure nodes (i.e. bridges, switches and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from/to clients.
Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle.
A network switch (also called switching hub, bridging hub, officially MAC bridge) is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device.
Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network.
In telecommunications networks, a node (Latin nodus, ‘knot’) is either a redistribution point or a communication endpoint.
Operations support systems (OSS), or operational support systems in British usage, are computer systems used by telecommunications service providers to manage their networks (e.g., telephone networks).
A payroll is a company's list of its employees, but the term is commonly used to refer to.
The public switched telephone network (PSTN) is the aggregate of the world's circuit-switched telephone networks that are operated by national, regional, or local telephony operators, providing infrastructure and services for public telecommunication.
In graph theory, reachability refers to the ability to get from one vertex to another within a graph.
In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
A router is a networking device that forwards data packets between computer networks.
Routing is the process of selecting a path for traffic in a network, or between or across multiple networks.
Routing in the PSTN is the process used to route telephone calls across the public switched telephone network.
A rush hour (American English, British English) is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest.
In the contexts of software architecture, service-orientation and service-oriented architecture, the term service refers to a software functionality or a set of software functionalities (such as the retrieval of specified information or the execution of a set of operations) with a purpose that different clients can reuse for different purposes, together with the policies that should control its usage (based on the identity of the client requesting the service, for example).
A Star network is one of the most common computer network topologies.
A subnetwork or subnet is a logical subdivision of an IP network.
The subscription business model is a business model where a customer must pay a subscription price to have access to a product or service.
A supercomputer is a computer with a high level of performance compared to a general-purpose computer.
In electrical engineering, a switch is an electrical component that can "make" or "break" an electrical circuit, interrupting the current or diverting it from one conductor to another.
A telecommunications network is a collection of terminal nodes, links are connected so as to enable telecommunication between the terminals.
A telephone exchange is a telecommunications system used in the public switched telephone network or in large enterprises.
In mathematics, and more specifically in graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path.
