Telephone remote dialling circuit - has central store and switching elements as one unit with hunter and store to control dialling process

摘要

The remote dialling circuit, for telephony, has its switching elements cooperating with a central store. They form one unit with the store. Only as many elements are provided as are needed to pass signals from the receiver via a hunter to a store. This store has circuitry which produces the dialling program and may use a data converter. Electromechanical rotary selectors are used to make the telephone connection.
