Director Telephone System
The Director System was a system which made it possible to call subscribers at other telephone exchanges without operator intervention in large multi-exchange cities, and to have a mixture of automatic and manual exchanges within these cities. It was introduced to six cities in the UK from 1927, starting with London, following the introduction of the automatic telephone exchange in the UK in 1912.
