circuit-switched data network
1Circuit Switched Data — (CSD) is the original form of data transmission developed for the time division multiple access (TDMA) based mobile phone systems like Global System for Mobile Communications (GSM). CSD uses a single radio time slot to deliver 9.6 kbit/s data… …
2Circuit Switched Data — (CSD)  технология передачи данных, разработанная для мобильных телефонов стандарта GSM. CSD использует один временной интервал для передачи данных на скорости 9,6 кбит/с в подсистему сети и коммутации (Network and Switching Subsystem NSS),… …
3Public switched data network — PSDN is an acronym for public switched data network, a publicly available network supporting packet switched data, separate from the PSTN.Originally this term referred only to PSS (Packet Switch Stream), an X.25 based packet switched network,… …
4High-Speed Circuit-Switched Data — (HSCSD), is an enhancement to Circuit Switched Data, the original data transmission mechanism of the GSM mobile phone system, four times faster than GSM, with data rates up to 38.4 kbit/s.As with CSD, channel allocation is done in circuit… …
5Circuit switching — is a methodology of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the …
6Public switched telephone network — The public switched telephone network (PSTN) is the network of the world s public circuit switched telephone networks. It consists of telephone lines, fiber optic cables, microwave transmission links, cellular networks, communications satellites …
7Network switching subsystem — (NSS) (or GSM core network) is the component of a GSM system that carries out call switching and mobility management functions for mobile phones roaming on the network of base stations. It is owned and deployed by mobile phone operators and… …
8Network performance — refers to the service quality of a telecommunications product as seen by the customer. It should not be seen merely as an attempt to get more through the network. The following list gives examples of Network Performance measures for a circuit… …
9Network Convergence — refers to the provision of telephone, video and data communication services within a single network. In other words, one pipe is used to deliver all forms of communication services. The process of Network Convergence is primarily driven by… …
10Network packet — In computer networking, a packet is a formatted unit of data carried by a packet mode computer network. Computer communications links that do not support packets, such as traditional point to point telecommunications links, simply transmit data… …
