TELEPHONE and TELEGRAPH Technology. We have partially restored this 1946 vintage film about TELEPHONE and TELEGRAPH Technology, showing many early electrical and electronic communications equipment in daily use. Glorious Black & White footage of teletype, switchboards, teleprinter, wire and microwave communication technology, installation and support as well as laboratory research. What similarities in procedures in use today? (runs 10 mins)
