Eirpac
EIRPAC is Ireland's packet switched X.25 data network. It replaced Euronet (telecommunications network), Euronet in 1984. Eirpac uses the Data Network Identification Code, DNIC 2724. HEAnet was first in operation via X.25 4.8Kb Eirpac connections back in 1985. By 1991 most Universities in Ireland used 64k Eirpac VPN connections. Today Eirpac is owned and operated by Eircom but does not accept new applications for Eirpac: no reference is made on the products-offering on their websiteReference to the service for existing customer is EircoPricelist checked 4 April 2011 They began the process of migrating existing customers using more capable forms of telecommunications back in late April 2004. In 2001 Eirpac had approximately 5,000 customers dialing in daily via switched virtual circuit's although those numbers have been declining rapidly. Eirpac is still an important element for data transfer in Ireland with numerous banks (automatic teller machines), telecoms switches, pager syste ...

Ireland
Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest on Earth. Geopolitically, Ireland is divided between the Republic of Ireland (officially Names of the Irish state, named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million living in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islan ...

Data Network Identification Code
X.121 is the ITU-T address format of the X.25 protocol suite used as part of call setup to establish a switched virtual circuit between Public Data Networks (PDNs), connecting two network user addresses (NUAs). It consists of a maximum of fourteen binary-coded decimal digits and is sent over the Packet Layer Protocol (PLP) after the packet type identifier (PTI). The address is made up of the international data number (IDN), which consists of two fields: the 4 digit data network identification code (DNIC) and the (up to) 10 digit national terminal number (NTN). The DNIC has three digits to identify the country (one to identify a zone and two to identify the country within the zone) and one to identify the PDN (allowing only ten in each country). The NTN identifies the exact network device (DTE, data terminal equipment) in the packet-switched network (PSN) and is often provided as an NUA. There are no rules to the structure of the NTN. IPv4 addresses can be mapped to X.121 as d ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Eircom
Eircom Limited, trading as Eir ( ; stylised eir), is a large fixed, mobile and broadband telecommunications company in Ireland. The now privatised company, which is currently incorporated in Jersey, traces its origins to the Ireland's former state-owned monopoly telecommunication provider Telecom Éireann and its predecessors, P&T (the Dept. of Posts and Telegraphs) and before the foundation of the state, the telecommunications division of the GPO. It remains the largest telecommunications operator in Ireland and has overseas operations focused on the business and corporate telecom markets in the United Kingdom. The company was in majority state ownership until 1999, when it was privatised through a floatation on the Irish and New York Stock Exchanges. Eir is currently majority owned by Xavier Niel's Iliad SA and his Paris-based NJJ Telecom Europe investment fund. The group includes French telecommunications provider Free and Iliad Italia.

Switched Virtual Circuit
A virtual circuit (VC) is a means of transporting data over a data network, based on packet switching and in which a connection is established within the network between two endpoints. The network, rather than having a fixed data rate reservation per connection, like in circuit switching, takes advantage of the statistical multiplexing on its transmission links (an intrinsic feature of packet switching, well suited to data traffic). In addition, VCs standardized by the CCITT in 1976 impose per-connection flow controls at all user-to-network and network-to-network interfaces. They thus eliminate the need for the network to lose user packets in heavily loaded network zones, an intrinsic feature of datagram networks for their congestion control. Before a connection or virtual circuit may be used, it must be established between two or more nodes or software applications by means of call setup. After that, a bit stream or byte stream may be delivered between the nodes; hence, a vir ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Automatic Teller Machines
An automated teller machine (ATM) or cash machine (in British English) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, funds transfers, balance inquiries or account information inquiries, at any time and without the need for direct interaction with bank staff. ATMs are known by a variety of names, including automatic teller machine (ATM) in the United States (sometimes redundantly as "ATM machine"). In Canada, the term ''automated banking machine'' (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM over ABM. In British English, the terms ''cashpoint'', ''cash machine'' and ''hole in the wall'' are most widely used. Other terms include ''any time money'', ''cashline'', ''tyme machine'', ''cash dispenser'', ''cash corner'', ''bankomat'', or ''bancomat''. ATMs that are not operated by a financial i ...

Hayes Command Set
The Hayes command set (also known as the AT command set) is a specific command language originally developed by Dennis Hayes for the Hayes Smartmodem 300 baud modem in 1981. The command set consists of a series of short text strings which can be combined to produce commands for operations such as dialing, hanging up, and changing the parameters of the connection. The vast majority of dial-up modems use the Hayes command set in numerous variations. The command set covered only those operations supported by the earliest 300 bit/s modems. When new commands were required to control additional functionality in higher speed modems, a variety of one-off standards emerged from each of the major vendors. These continued to share the basic command structure and syntax, but added any number of new commands using some sort of prefix character – & for Hayes and USR, and \ for Microcom, for instance. Many of these were re-standardized on the Hayes extensions after the introduction of t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Computer Networking
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications protocols ...
