Overview
Telecom Éireann was Ireland's state-owned telecommunications operator from 1983 until 1999. Its creation separated telecommunications operations from the broader civil-service functions of the Department of Posts and Telegraphs, historically known as P and T. The company was formally constituted under the Postal and Telecommunications Services Act 1983 as Bord Telecom Éireann, with Telecom Éireann used as the English-language brand and public-facing identity. The company operated during a major transition in Irish communications. At the beginning of its existence, parts of the national telephone network still relied on ageing electromechanical exchanges, including step-by-step and crossbar systems. Telecom Éireann undertook a wide-ranging modernisation programme, replacing analogue and older electromechanical infrastructure with digital switching, fibre-optic transmission and digital microwave links. It selected CIT-Alcatel E10 and Ericsson AXE switching platforms, progressively converting local and regional exchanges as well as international gateways. By the middle of the 1990s, the Irish network had become fully digitally switched, a significant transformation for a country whose telecommunications infrastructure had previously lagged behind that of several other European markets. The operator expanded beyond conventional fixed-line telephony. Its activities included Eirpac, a public switched data network supporting X.25 and X.28 services; Eirpage, a national paging service; TEIS, which supplied business systems and office telephone systems; Telecom Internet, later known as Tinet and subsequently associated with eircom net; and TeleCentre, a retail network that provided customer-facing services. The company also participated in PhoneWatch, a monitored alarm business serving residential and commercial customers. In the late 1980s it upgraded Ireland's public payphone estate and introduced Telecom Éireann CallCard smart-card payphones, an early large-scale use of chip-based telephone cards. Mobile communications became one of the company's most important growth areas. Telecom Éireann established Eircell in 1984, with network operations beginning in 1986. The first network used TACS, a first-generation analogue mobile standard also used in the United Kingdom. Eircell then introduced a GSM digital network in 1993, allowing customers to migrate from the increasingly outdated analogue service. Eircell later became the foundation of Vodafone Ireland after its sale to Vodafone in 2001. Telecom Éireann also experimented with emerging information services. In 1991 it launched Minitel Ireland in a joint venture with France Telecom, Allied Irish Banks and Crédit Lyonnais. The service offered a videotext platform intended to support information, banking and shopping applications, but uptake remained weak. Its late arrival, combined with the rapid emergence of the World Wide Web, limited its commercial relevance and it was eventually closed. The company entered a more commercially oriented phase in the 1990s. In June 1996, Telecom Éireann formed a strategic alliance with Telia of Sweden and KPN of the Netherlands after the two companies acquired a combined 35 percent interest. During this period, Telecom Éireann maintained Dublin offices associated with St Stephen's Green and Harcourt Street. The alliance did not remain permanent: Telia and KPN later exited Ireland, with the process completed by 2001. Telecom Éireann was privatised in 1999 and renamed eircom plc. The reorganisation separated the mobile business into Eircell 2000 plc and left the fixed-line operator and several other activities within eircom. Eircell was sold to Vodafone in May 2001 and ultimately became Vodafone Ireland. The Telecom Éireann name therefore survives primarily as a historical marker of Ireland's transition from a state-administered telephone service to a digitally networked and commercially operated telecommunications market.
History
Telecom Éireann emerged from the reorganisation of Ireland's public communications administration. Before 1983, telephone and postal services were provided within the Department of Posts and Telegraphs, commonly called P and T. The Postal and Telecommunications Services Act 1983 created Bord Telecom Éireann, giving telecommunications a separate state-owned corporate structure. Telecom Éireann became the public brand used for the new operator, whose formal title could be rendered in English as The Irish Telecommunications Board. Its central historical task was the modernisation of Ireland's telephone network. The company inherited a mixture of manual exchanges and electromechanical equipment, including step-by-step and crossbar systems installed during earlier decades. It introduced digital switching at local, regional and international levels, using CIT-Alcatel E10 and Ericsson AXE systems. The modernisation was supported by a national fibre-optic and digital microwave backbone. Older manual and electromechanical exchanges were progressively replaced, and by the mid-1990s the network was fully digitally switched. This programme made the Irish system one of the more extensively digitised national networks of its period. The operator also modernised public access to telephony. During the late 1980s it upgraded public payphones and introduced the Telecom Éireann CallCard, a smart-card telephone payment system. The company developed several specialist divisions, including Eirpac, an X.25 and X.28 public switched data network launched in 1984; Eirpage, a national paging service; and TEIS, which sold business systems and office telephone equipment. TeleCentre served as the retail arm and was later continued under the eircom Store name. Mobile communications provided a major new line of business. Telecom Éireann created Eircell in 1984, with service beginning in 1986 through a national TACS analogue network. In 1993, Eircell launched a GSM network supplied using Ericsson technology. Digital service rapidly displaced TACS as customers moved to GSM handsets and subscriptions, and the analogue network was eventually withdrawn. Eircell later became a separately identifiable asset during the transition to eircom and was sold to Vodafone in 2001. Telecom Éireann experimented with consumer and business services associated with the emerging information economy. Minitel Ireland was introduced in 1991 through a joint venture involving France Telecom, Allied Irish Banks and Crédit Lyonnais. It was intended to provide videotext-based shopping, banking, information and other services. However, its limited user base and the rapid rise of the Web reduced its prospects, and the service was closed. In 1997 the company established Telecom Internet, or Tinet, which became part of the lineage leading to eircom net. The company also operated or supported adjacent services. PhoneWatch supplied monitored alarm services to residential and business customers. Telecom Éireann sponsored RTÉ Weather from 1988 until 1999, giving the brand a prominent association with Irish television. Its public identity also appeared in Irish popular culture, including references and visible branded equipment in television programmes. A strategic alliance formed in June 1996 brought Telecom Éireann into a closer relationship with Telia of Sweden and KPN of the Netherlands, which together acquired a 35 percent interest. The company was associated with offices at St Stephen's Green and Harcourt Street in Dublin during this period. The alliance was transitional: Telia and KPN later withdrew, with their exit completed by 2001. In 1999 the Irish telecommunications operator was privatised and renamed eircom plc. The restructuring divided the former business into Eircell 2000 plc for mobile operations and eircom for fixed-line telecommunications and other activities. The Telecom Éireann brand consequently became defunct as a corporate identity, although much of its infrastructure, service portfolio and mobile business continued under successor companies. Its history represents Ireland's movement from a government department delivering basic telephony toward a fully digital, diversified and commercially organised communications sector.
