Dial operated mobile radiotelephone systems

This paper describes radiotelephone equipment that makes it possible for small telephone companies with dial exchanges to offer 24-hour mobile radiotelephone service to its subscribers. Similar radiotelephone service can be given to subscribers in remote locations who could not otherwise be served by conventional wire line facilities. The equipment may also be used by a telephone company for its own use incident to construction and maintenance of outside plant. The equipment was developed to Rural Electrification Administration specifications by the Automatic Electric Company and Motorola, Inc., under separate contracts and has been successfully field-tested. The telephone exchanges of most REA borrowers are of the automatic dial type and very few borrowers have toll centers with operators available to handle mobile calls. Lacking switchboard operators, these small companies can offer mobile radiotelephone service to their subscribers only on a limited dispatch or an automatic dial-operat operated basis.
