Events in telecommunications history

1973

The world's first experimental international Confravision (video conference) link was set up by the Post Office between London and Sydney, Australia.

The Post Office telecommunications monopoly in the Channel Islands ended on 1 January with the transfer of responsibility for running such services to the States of Guernsey (covering Guernsey, Alderney, Sark, Herm and Brechou) and Jersey.

The Post Office adapted the hovercraft principle to move pre-packed containers of submarine cable weighing up to 70 tons at its new Southampton cableship depot.

The first mobile electronic exchange was brought into service.

The last London Telecommunications Region exchange to be converted went STD at Nazeing, Essex.

The last Siemens 16 exchange was withdrawn from service on 17 January at Portslade, Sussex.
