In the Sixties, telephone exchange 'open days' were an opportunity
for the G.P.O. to promote its services and for the public to see the
latest developments in the switching of calls. Visits to an
AutoManual Centre were particularly interesting as you could see
both the operators at work and the equipment used to connect the
calls. Children could visit the place where their parents worked and
perhaps long to be an operator or engineer when they grew up.
Opposite is a typical 'open day' leaflet produced in 1968.
"This leaflet is provided to assist you during and after your visit.
Your guide will be pleased to answer any questions."

Heart of the Operator Services; connecting calls, dealing with
emergencies, providing a public service.
Today, there are very few calls that cannot be directly dialled by
the customer, but this was not always the case...

In the 21st century, virtually all (UK) telephone and data traffic
is processed by digital switches. In this section we look back to a
time when Strowger, Crossbar and Electronic switching carried the
bulk of the calls...
We also find out about the development of Subscriber Trunk Dialling
(STD) which greatly simplified the call set-up process.

The first International Subscriber Dialling (ISD) call was made by
the Lord Mayor of London (Sir Ralph Perring) at 11am on 8th March
1963. Calling from Fleet Building, he dialled 13 digits and was
connected to Monsieur Jacques Marette, the French Minister of Posts,
Telegraphs and Telephones, in Paris.

The GPO Tower
The Postmaster General, Anthony Wedgwood Benn, said that the Post
Office Tower symbolised 20th-century Britain. Lean, practical and
futuristic, it epitomised the technical and architectural skills of
the second industrial revolution.
