1.The worldwide voice telephone network. 2. Any common carrier network that provides circuit switching among public users.

PSTN is the designation for the public telephone network.

The concatenation of the world's public circuit switched telephone networks, in much the same way that the internet is the concatenation of the world's public IP-based packet switched networks. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital, and now includes mobile as well as fixed telephones. (source)

This refers to the international voice telephone network accessible legally to all.

(PSTN) Any switching communications system such as Telex, TWX, or public telephone networks that provides circuit switching to many customers.

See PSTN.

PSTN simply refers to the local, long distance and international phone system that we use every day. In some countries, it's only one phone company. In competitive companies, like the US, PSTN refers to the entire interconnected collection of phone companies.

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 normal 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.

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.

The global public telephone network.

A Public Switched Telephone Network (PSTN) denotes those portions of the LEC and IXC networks that provide public switched telephone network services.

a traditional fixed telephone network, designed for voice transmission. It also allows data transfer through a modem and computer.

The dial up public telecommunications network.

PSTN) The switched telephone networks of the major operators, on which calls can be made to all customers of all PSTN s. The Telecommunications Act 2001 defines a PSTN as "a dial-up telephone network used, or intended for use, in whole or in part, by the public for the purposes of providing telecommunication between telephone devices.

Worldwide telephone system that handles voice-oriented telephone calls. 9.25

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.

The regular, "old-fashioned" telephone network.

PSTN - the telecommunications networks of the major operators, on which calls can be made to all customers of all PSTNs.

The public telephone network which provides the capability of interconnecting any home or office with any other.

Refers to the international telephone system based on copper wires carrying analogue 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 (POTS).

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.

A generic term for the collection of networks which provide public telephone switching service.

The switched telephone telecommunications network to which public customers are connected.

Also referred to as the "Plain Old Telephone System (POTS)," the PSTN is the circuit-switched phone system, with analog local loops, largely in use today.

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 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.

The worldwide switched telephone network provided by local exchange carriers (LECs) and interexchange carriers (IXCs) in the United States and internationally.

Also know as Plain Old Telephone System, this refers to the world's collection of interconnected public telephone networks designed primarily for voice traffic.

(PSTN) The nationwide telephone switching system operated by various telephone companies which enables the general public to communicate.

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.

Infrastructure providing a country's telephone system. It is the means by which household and business phones are connected, typically by conventional fixed cables.

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).

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.

The public networks that deliver telephone services worldwide.

Standard analog telephone lines, available worldwide.

Traditional landline network that mobile wireless systems connect with to complete calls.

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.
