Telecom Éireann: История ирландской телекоммуникационной компании

Irish telecommunications company active from 1983 to 1999

Telecom Éireann (; meaning "Telecommunications of Ireland") was an Irish state owned telecommunications company that operated from 1983 to 1999. Prior to then a telephone and postal service was provided by the Department of Posts and Telegraphs (known as "P and T" or "P⁊T" in Gaelic script), as part of the civil service. Telecom Éireann was established by the Postal and Telecommunications Services Act, 1983; its full formal title was "Bord Telecom Éireann or, in the English language, The Irish Telecommunications Board". "Telecom Éireann" may be translated as "Telecom of Ireland". In 1999, the company was privatised and renamed as eircom.

Telecom Éireann rolled out digital telephone switching technology, across the country along with an extensive fibre optic and digital microwave backbone. Two digital switching systems were selected; CIT Alcatel's E10 and Ericsson's AXE telephone exchange. Digital technology quickly replaced analogue systems at national and major regional switching centres and new international gateway switches were installed. The oldest electromechanical step by step exchanges and manual operator manned local exchanges were the first to be converted to digital technology. More modern electromechanical crossbar exchanges, using Ericsson ARF, Hitachi and ITT Pentaconta technology dating from the 1960s and 1970s were converted to digital bit by bit through the late 1980s and early 1990s. These crossbar switches were capable of providing voice service that was comparable to digital switching technology. By the early 1990s, the Irish network was amongst the most modern and most digitalised in the world and by the mid 1990s and had become 100% digitally switched. In June 1996, a strategic alliance was formed between Telecom Éireann of Ireland, Telia of Sweden and KPN of the Netherlands, after both companies purchased a combined 35 percent stake in Telcom Éireann. The alliance was completed by 2001, when Telia and KPN exited Ireland. During the time of the alliance it was headquartered in St Stephens Green and Harcourt Street, Dublin. The company also did a major upgrade to the payphone network in the late 1980s, which saw the rollout of smart card based payphones across Ireland. The Telecom Éireann CallCard was one of the earliest implementations chip based cards in the world.

Telecom Éireann launched Eircell (now Vodafone Ireland) in 1984, with operations commencing in 1986. The company deployed a national mobile telephone network based on a first generation mobile technology known as the Total Access Communication System, or TACS for short. This technology, similar to AMPS, was also used in the UK by Vodafone and Cellnet. Eircell launched their digital network based on GSM technology from Ericsson in 1993. GSM service rapidly replaced the TACS network as customers migrated over to new digital technology. Within a few years, the TACS network was obsolete and taken off air.

In 1988, it sponsored RTÉ Weather until 1999.

Telecom Éireann was privatised in 1999 and renamed as eircom plc. It was later split into Eircell 2000 plc (Eircell), the mobile networks business, and eircom, the fixed line business which also inherited other minor divisions, such as the Eirpage pager system and the Telecom retail arm. Eircell was sold to Vodafone in May 2001, and later changed its name to the dual brand Eircell Vodafone before becoming Vodafone Ireland.

In the BBC TV series Coupling, a phone with a Telecom Éireann logo appears in the episode "Gotcha". In the Channel 4 Series Father Ted(Speed 3) a Telecom Éireann kiosk is seen near the end.
