Wire Broadcast Warning Systems for the Future | BT Heritage

(Note: Low volume) A video explaining how, starting in 1982, the new early warning system was to replace the old 1960s system. The system comprised of two Wire Broadcast services: ’HANDEL’ or WB1800 for unidirectional speech from the Air Defence centre to 250 carrier control points (CCPs) in police stations and the WB1400 system to provide speech to 20,000 Warning Points and control of 7,000 siren control. The WB1400 system was used for both air attack warning and for flood warning in Essex, Kent and London. Date: 1 September 1982
