Telecommunications

An escape sequence is a series of characters used to change the state of computers and their attached peripheral devices.

Data integrity is the maintenance of, and the assurance of the accuracy and consistency of, data over its entire life-cycle, and is a critical aspect to the design, implementation and usage of any system which stores, processes, or retrieves data.

Digital multimedia broadcasting (DMB) is a digital radio transmission technology developed in South Korea as part of the national IT project for sending multimedia such as TV, radio and datacasting to mobile devices such as mobile phones, laptops and GPS navigation systems.

The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is an architectural framework for delivering IP multimedia services.

Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile phones and data terminals.

In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver.

In radio, multiple-input and multiple-output, or MIMO (pronounced /ˈmaɪmoʊ/ or /ˈmiːmoʊ/), is a method for multiplying the capacity of a radio link using multiple transmit and receive antennas to exploit multipath propagation.

Push-to-talk (PTT), also known as press-to-transmit, is a method of having conversations or talking on half-duplex communication lines, including two-way radio, using a momentary button to switch from voice reception mode to transmit mode.

The exit status or return code of a process in computer programming is a small number passed from a child process (or callee) to a parent process (or caller) when it has finished executing a specific procedure or delegated task.

Telematics is an interdisciplinary field that encompasses telecommunications, vehicular technologies, road transportation, road safety, electrical engineering (sensors, instrumentation, wireless communications, etc.), and computer science (multimedia, Internet, etc.).

Token bus is a network implementing the token ring protocol over a "virtual ring" on a coaxial cable.

A Registered Jack (RJ) is a standardized telecommunication network interface for connecting voice and data equipment to a service provided by a local exchange carrier or long distance carrier.

In telecommunications a link is a communications channel that connects two or more communicating devices.

The European Telecommunications Standards Institute (ETSI) is an independent, not-for-profit, standardization organization in the telecommunications industry (equipment makers and network operators) in Europe, headquartered in Sophia-Antipolis, France, with worldwide projection.

Dry contact may mean any of the following in electronics: * No current: A dry contact is the synonym of volt free - it is not "wetted" by a voltage source.

A digital cross-connect system (DCS or DXC) is a piece of circuit-switched network equipment, used in telecommunications networks, that allows lower-level TDM bit streams, such as DS0 bit streams, to be rearranged and interconnected among higher-level TDM signals, such as DS1 bit streams.

A public data network is a network established and operated by a telecommunications administration, or a recognized private operating agency, for the specific purpose of providing data transmission services for the public.

In communications and electronics, especially in telecommunications, interference is anything which modifies, or disrupts a signal as it travels along a channel between a source and a receiver.

Network transparency in its most general sense refers to the ability of a protocol to transmit data over the network in a manner which is transparent (invisible) to those using the applications that are using the protocol.
