Lightstraw UK making clear sense of telecommunications history

online since 19th August 1997
Topic Overview  
Light Straw looks back at the history of the Public Switched Telephone Network (PSTN), exchanges, telephones, vehicle fleets, and its organisational structure, and attempts to encapsulate the wonderment of bygone eras of the Post Office/GPO/Britsh Telecom, and Openreach.

Enter the world of operator connected calls, Subscriber Trunk Dialling, Strowger switching and much more...

Visit the Post Office Tower; the Telephone Managers' Office; explore the Telecoms Engineering Centre; and learn about the last two TXE4s to be taken out of service. Tour Bletchley Park where GPO equipment helped to crack the German wartime codes.


Includes GPO Clock Systems.
