ublic witched elephone etwork. The key word is public. This is the main telephone system owned by a telecommunications company. When you ring someone with a white pages or yellow pages phone number you are probably using a PSTN phone line. See also .
Public Switch Telephone Network. Refers to the fixed telephone network that is served by interconnected exchanges (local exchange, regional exchange, international exchange). An exchange is a telephone switch that functions to establish, maintain, and terminate telephone connections. Compare with PLMN.
Publicly switched telephone network. The world-wide dial-up telephone network or a portion of that network. Whatever system you own should be linked somehow to the PSTN so you can make long distance phone calls, or go on the Internet.
Public Switched Telephone Network. Often used to refer to the entire national or global telephone infrastructure, this is more accurately used to refer to the local telephone service provider. It is also referred to as POTS, or Plain Old Telephone Service.
Public Switched Telephone Network. The PSTN is the traditional telephone network used worldwide to carry majority of voice traffic. The PSTN is typically built on circuit-switched technology patforms, whereas IP telephony networks are built on packet-switched technology platform.
The PSTN is composed of all transmission and switching facilities and signal processors supplied and operated by all telecommunications common carriers for use by the public. Every station on the PSTN is capable of being accessed from every other station on the PSTN.
Public Switched Telephone Network. A global network of interconnected digital and analogue communication links. Functions in the Physical layer by providing dial-up and leased lines for the interconnections. The Internet in most homes is over the PSTN. If you live in the Hull area, you have to use Kingston Communications, who charge double the rates that British Telecom does to connect to the internet 24/7. That is because OFTEL think do not understand the meaning of the word "Monopoly". Apparently Kingston do not have a monopoly because people can always move to London if they want to use British Telecom. Thanks guys.
Public Switched Telephone Network. A circuit-switched analogue network which makes connections for the duration of telephone call. These connections are usually used for voice but can also carry data between facsimile machines and computers (via a modem).
Public Switched Telephone Network, a global network of interconnected digital and analog communication links originally designed to support voice communication between any two points in the world but quickly adapted to handle digital data traffic when the computer revolution occurred. In addition to its traditional voice support role, the PSTN now functions as the Physical lyaer of the Internet by providing dial-up and leased lines for private, exclusive use.
(Public Switched Telephone Network) The public phone system which includes telephones, local lines, local exchanges and the complete system of trunks and the exchange hierarchy which makes up the network
Public Switched Telephone Network This refers to the analog telephone network that's very common in residential networks. PSTN lines are usually much cheaper then T1 lines, but only provide one channel. Digium's FXO and FXS modules interface with this network. See also: FXO, FXS
Public Switched Telephone Network. A domestic telecommunications network usually accessed by telephones, key telephone systems, private branch exchange trunks, and data arrangements. Note: Completion of the circuit between the call originator and call receiver in a PSTN requires network signaling in the form of dial pulses or multifrequency tones.
Public Switched Telephone Network was put into place many years ago as a voice telephone call-switching system. The system transmits voice calls as analog signals across copper twisted cables from homes and businesses to neighborhood COs (central offices); this is often called the local loop. The PSTN is a circuit-switched system, meaning that an end-to-end private circuit is established between caller and the person called.
Public Switched Telephone Network. General term referring to the world's collection of interconnected voice-oriented public telephone networks, both commercial and government-owned. Sometimes called POTS (plain old telephone service).
Public Switched Telephone Networks. The conventional network on which telephone calls are made. Internet The Internet is a global system of telephone, cable and data networks. It is a network of networks. It enables commercial organisations, individuals, educational institutions and government agencies to communicate, exchange data and engage in a growing variety of commercial activities in an international, real-time environment.
Public switched telephone network. The worldwide dial-up telephone network or a portion of that network (e.g., the Bell Canada PSTN). A phrase often used when referring to data or other non-telephone services carried over a path initially established using normal telephone signaling and ordinary switched long distance telephone circuits.
Public switched telephone network. A direct distance dialing telephone network that is available for public use. The network is an integrated system of transmission and switching facilities signaling processors and associated operations support systems that is shared by customers.
The PSTN (Public Switched Telephone Network) is the term given to the collection of the world's interconnected voice-oriented public telephone networks. Today, the PSTN is almost completely digital, aside from the final connection from the central (local) office to the user. PSTNs also create much of the Internet's long distance infrastructure.
Public Switched Telephone Network. Quad Splitter Combines up to 4 video inputs into one channel and displays them on one monitor screen split into 4. AM Random Access Memory. The place in a computer where the operating system, application programs, and data in current use are kept temporarily so that they can be quickly reached by the computer's processor.
Edit / Public Switched Telephone Network - The "old" telephone network (still very much in use today) that set up calls by creating a physical electrical path, or “connection” from the originating number to the destination number. Modern networks are “connectionless” and rout packets containing digitized audio voice information as it is produced. See Also: POTS
The Public Switched Telephone Network is the public, wire-line, switched network based on TDM circuits and used to transport PCM-encoded voice calls. It is often times referred to as the SCN, or Switched Circuit Network, by those in the packet-switched data network world.
Public Switched Telephone Network. A Public Switched Telephone Network (PSTN) exists as those sections of the LEC and IXC networks that operate to provide telephone network services that are public switched.
(Public Switched Telephone Network) - The worldwide voice network that has evolved since the advent of the telegraph. Due to its ubiquity, the PSTN has been turned to other uses. Although originally analog in nature, the PSTN has transformed into primarily a digital carrier. As a result, it has been able to increase capacity and serve as the infrastructure for virtually all telecommunications, including the Internet.
Public Switched Telephone Network. Public switched telephone networks are communication systems that are available for public to allow users to interconnect communication devices. Public telephone networks within countries and regions are standard integrated systems of transmission and switching facilities, signaling processors, and associated operations support systems that allow communication devices to communicate with each other when they operate.
Acronym for Public Switched Telephone Network. What most telephones in the U.S. are a part of. This is what all local public telephone companies are a part of. The PSTN is regulated by the FCC, and if you connect to it, you must obey certain standards and protocols (see Data Access Arrangement.)
Public switched telecommunications network. a fully interconnected and integrated system of telecommunications consisting of various means of transmission and switching, utilised to provide basic telephone services to the general public.
(Public Switched Telephone Network). The telephone network ubiquitous over the world. Its components are telephones, RJ-11 twisted-pair cabling, and the central office. PSTN is also called POTS (plain old telephone service). The main reason PSTN has not be replaced with a newer technology such as ISDN is that PSTN works when electrical power is out. ISDN requires a separate power supply. Also see ISDN POTS RJ-11 Twisted pair (TP)
Public Switched Telephone Network. The network of wires, signals, and switches that lets one phone connect to another anywhere in the world. Some VoIP services provide a gateway from the Internet to the PSTN and vice versa.
The international telephone system based on copper wires carrying analog voice data. This is in contrast to newer telephone networks base on digital technologies, such as ISDN and FDDI. Telephone service carried by the PSTN is often called plain old telephone service or POTS.
Public Switched Telephone Network. The Wide Area Network (WAN) that is available to all users in a region. Compare to private networks which are owned or leased by individual companies or subscribers. In some regions of the world, the PSTN is operated by government entities, while in others they are operated by public utility companies. The PSTN is evolving now into the global Public Switched Network (PSN) to carry not only voice traffic, but data and video traffic as well.
Public switched telephone network. PSTN is the international collection of interconnected voice-oriented public telephone networks, both commercial and government-owned. It's also referred to as the Plain Old Telephone Service.
Public Switched Telephone Network. The network that is usually considered the incumbent telephone system. It is Public because it has open-access requirements. It is considered switched because it sets up calls with dedicated connections or circuits (in contrast to IP networks, for example, which are connectionless).
Public Switched Telephone Network. The world's collection of interconnected voice-oriented public telephone networks, both commercial and government-owned. The PSTN is the aggregation of TDM circuit-switched telephone networks that has evolved from the days of Alexander Graham Bell. Today, it is almost entirely digital in technology except for the final link from the central (local) telephone office to the user. It is also referred to as the Plain Old Telephone Service (POTS) or the Switched Circuit Network (SCN).
PSTN is the abbreviation used to describe the voice telephone network. It stands for Public Switched Telephone Network, the word "switched" referring to the physical switching of electronic circuits which takes place when you make a call.
Public Switched Telephone Network. The regular telephone network, or any part of it. Along with telephone services, this network also carries data and other non-telephone services via conventional switched telephone circuits using regular telephone signaling.
Public Switched Telephone Network. The PSTN is the worldwide circuit-switched telephone network. Once only an analog system, telephone networks today increasingly are digital, even though most subscribers are connected via analog circuits.
