Standards Organization
A standards organization, standards body, standards developing organization (SDO), or standards setting organization (SSO) is an organization whose primary function is developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise contributing to the usefulness of technical standards to those who employ them. Such an organization works to create uniformity across producers, consumers, government agencies, and other relevant parties regarding terminology, product specifications (e.g. size, including units of measure), protocols, and more. Its goals could include ensuring that Company A's external hard drive works on Company B's computer, an individual's blood pressure measures the same with Company C's sphygmomanometer as it does with Company D's, or that all shirts that should not be ironed have the same icon (a clothes iron crossed out with an X) on the label. Most standards are voluntary in the sense that they are offered for adoption by people ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Telecommunication Standardization Assembly
The World Telecommunication Standardization Assembly (WTSA) is the governing conference of the ITU Standardization Sector (ITU-T), one of the three world conferences of the International Telecommunication Union, and as such, the United Nations system. The quadrennial conference decides the working methods for ITU-T for the next Study Period. It also creates the Telecommunication Standardization Advisory Group (TSAG) and the ITU-T Study Groups (such as ITU-T Study Group 16) and elects their management teams. The Recommendations and resolutions that are approved at WTSA shape the future of ICT standardization. WTSA 20 WTSA 20 was scheduled to be held in Hyderabad, India in 17-27 November 2020. It was rescheduled to 1-9 March 2022 at CICG, next to ITU headquarters in Geneva, Switzerland, due to the COVID-19 pandemic. WTSA 16 WTSA-16 was held from 25 October until 3 November 2016 in Hammamet, Tunisia. WTSA 12 The World Telecommunication Standardization Assembly in 2012 (WTS ...

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 is responsible for coordinating standards for telecommunications and Information Communication Technology such as X.509 for cybersecurity, Y.3172 and Y.3173 for machine learning, and H.264/MPEG-4 AVC for video compression, between its Member States, Private Sector Members, and Academia Members. The first meeting of the World Telecommunication Standardization Assembly (WTSA), the sector's governing conference, took place on 1 March of that year. ITU-T has a permanent secretariat called the Telecommunication Standardization Bureau (TSB), which is based at the ITU headquarters in Geneva, Switzerland. The current director of the TSB is Chaesub Lee (of South Korea), whose first 4-year term commenced on 1 January 2015, and whose second 4-year term commenced on 1 January 2019.

GPON
G.984, commonly known as GPON (gigabit-capable passive optical network), is a standard for passive optical networks (PON) published by the ITU-T. It is commonly used to implement the outermost link to the customer (last kilometre or last mile) of fibre-to-the-premises (FTTP) services. GPON puts requirements on the optical medium and the hardware used to access it, and defines the manner in which ethernet frames are converted to an optical signal, as well as the parameters of that signal. The bandwidth of the single connection between the OLT (optical line termination) and the ONTs ( optical network terminals) is 2.4Gbit/s down, 1.2Gbit/s up, or rarely symmetric 2.4Gbit/s, shared between up to 128 ONTs using a time-division multiple access (TDMA) protocol, which the standard defines. GPON specifies protocols for error correction ( Reed–Solomon) and encryption ( AES), and defines a protocol for line control ( OMCI) which includes authentication. Though implementations of GPON sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
International Telecommunication Union
The International Telecommunication Union is a specialized agency of the United Nations responsible for many matters related to information and communication technologies. It was established on 17 May 1865 as the International Telegraph Union, making it the oldest UN agency. The ITU was initially aimed at helping connect telegraphic networks between countries, with its mandate consistently broadening with the advent of new communications technologies; it adopted its current name in 1932 to reflect its expanded responsibilities over radio and the telephone. On 15 November 1947, the ITU entered into an agreement with the newly created United Nations to become a specialized agency within the UN system, which formally entered into force on 1 January 1949. The ITU promotes the shared global use of the radio spectrum, facilitates international cooperation in assigning satellite orbits, assists in developing and coordinating worldwide technical standards, and works to improve tele ...
