The Subscriber Trunk Dialling (STD) service, whereby telephone callers are able to make trunk calls automatically without the aid of the operator, was introduced into the United Kingdom by the Queen dialling a call on 5 December from Bristol Central Telephone Exchange to the Lord Provost of Edinburgh, over 300 miles away - the greatest distance over which a subscriber trunk call could be made at the time. Afterwards, the Queen operated a switch which put 18,000 telephones connected to Bristol Central onto the new system.
