Working History — C. 2000
Card, signalling card
Keybridge House was built in the 1970s to house both an international and an inland telex exchange. Keybridge was also designed as a trunk telephone exchange (an exchange that connects other exchanges) for London and the South East and as a telephone service centre where a large team of engineers was based. In 1984 Keybridge became a state-of-the-art international digital telephone exchange.
This NTU 6B/2 signalling card was taken from Keybridge's Ericsson System Y digital exchange and was used for the Royal Bank of Scotland's data service from Gibraltar to London.
