Abstract
A typing station at a remote location having a central processing unit and a terminal is interconnected with an information storage and retrieval system via a single telephone line. A typist at the remote location depresses a foot pedal associated with the central processing unit and controls shared transmission of audio messages and digital data between the typing station and the information storage and retrieval system. When the foot pedal is depressed, audio information is transmitted from the information storage and retrieval system at a central location to the typing station at the remote location. When the foot pedal is released, digital data defining previously transcribed audio information which is stored in the central processing unit is transmitted to the information storage and retrieval system via the single telephone line.
