D J Cree, A.J. Whittaker · Radio and Electronic Engineer · 1980
A large area coverage radio system with telephone access is described. Two operator-controlled systems have been installed on British Rail. This paper describes the development of a stored program automatic radio connection system, which allows direct dialling between individual mobile radio users and access to the British Rail automatic trunk telephone network. Emergency override access from the mobile radios is provided.
