Dublin telephone users can now access most countries in the world without going through an operator.
A new international telephone exchange in Dublin is opened by Minister for Posts and Telegraphs Dr Conor Cruise O'Brien.
It is expected that the new exchange will mean a reduction in the cost of telephone calls to locations around Europe. Ireland will now have around 200 international circuits and a capacity for around 8,000 calls an hour.
While direct international calls can now be made from the Dublin area, diallers in the rest of the country will still have to go through an operator but there are plans to extend the service nationwide.
