Plesiochronous system

Index Plesiochronous system

In telecommunications, a plesiochronous system is one where different parts of the system are almost, but not quite, perfectly synchronised. [1]

Asynchronous serial communication

Asynchronous serial communication is a form of serial communication in which the communicating endpoints' interfaces are not continuously synchronized by a common clock signal.

Clock drift

Clock drift refers to several related phenomena where a clock does not run at exactly the same rate as a reference clock.

Data buffer

In computer science, a data buffer (or just buffer) is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another.

Ethernet

Ethernet is a family of computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN).

Greek language

Greek (Modern Greek: ελληνικά, elliniká, "Greek", ελληνική γλώσσα, ellinikí glóssa, "Greek language") is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean and the Black Sea.

Isochronous timing

A sequence of events is isochronous if the events occur regularly, or at equal time intervals.

ITU-T

The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU); it coordinates standards for telecommunications.

Jitter

In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal.

Mesochronous network

In telecommunication, a mesochronous network is a network in which the clocks run with the same frequency but unknown phases.

Plesiochronous digital hierarchy

The plesiochronous digital hierarchy (PDH) is a technology used in telecommunications networks to transport large quantities of data over digital transport equipment such as fibre optic and microwave radio systems.

Synchronization

Synchronization is the coordination of events to operate a system in unison.

Synchronization in telecommunications

In telecommunications, a synchronous network is a network in which clocks are controlled to run, ideally, at identical rates, or at the same mean rate with a fixed relative phase displacement, within a specified limited range.

Synchronous circuit

A synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal.

New!!: Plesiochronous system and Synchronous circuit · See more »

Synchronous optical networking

Synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) are standardized protocols that transfer multiple digital bit streams synchronously over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs).

Systems engineering

Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles.

Telecommunication

Telecommunication is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, optical or other electromagnetic systems.
