SEMI-AUTOMATED DIRECTORY ASSISTANCE SYSTEMS

A semi-automatic directory assistance system uses a directory assistance computer to help an operator at an operator position terminal find the requested directory number. The control processor, a module control unit, of a module of the system controls the establishment of part of the connection from a subscriber requesting operator assistance to the operator position. The operator at the operator position communicates with the directory assistance computer to find the requested number. After the requested number has been found, the computer sends a message to the control processor. In response to that message, the control processor causes an audio response unit to generate a directory assistance message corresponding to the desired number and causes the response unit to be connected to the subscriber.
