Abstract

An interface adapter is disclosed for utilization with a conventional toll operator position system having a keyboard, video display and controller which interface adapter interface with the TOPS position and external data bases and audio response units in a manner to permit the TOPS position to additionally perform such functions as directory assistance, order entry and line message delivery. The interface adapter includes first and second switching means to intercept the keyboard and video data paths of the TOPS position to isolate the controller and includes a control processor in communication with the external data bases and audio response units which is programmed to respond upon command from the keyboard to access the external data bases and audio response units as required and to communicate such data or audio response to the appropriate terminus.

Claims

1. In a telephone communications system employing a traffic operator system having a keyboard, video display, controller, a keyboard data path between the keyboard and controller and a video signal path between the video and controller providing toll and local operator assistance and equipment including external data bases and audio response units to provide services including directory assistance, the improvements of an interface adapter permitting utilization of the operator system for the dual function of handling normal operator traffic while providing additional access to external data bases and audio response units to provide services including directory assistance comprising:

first switching means to intercept the keyboard data path;

second switching means to intercept the video data path; and

data processing means in communication with the external data bases and audio response units and programmed to respond upon command from the keyboard to access the external data bases and audio response units as requested and to display and communicate such data or audio response to the appropriate terminus.

2. The telephone communications system of claim 1 wherein the data processing means includes terminal emulator firmware for receipt of data from remote data bases to convert the data for video display of the data base information so received.

3. The telephone communications system of claim 1 wherein the data processing means includes keyboard interpreter firmware to receive and interpret keyboard data for direction and control of the data processing means.

4. The telephone communications system of claim 3 wherein the data processing means further includes keyboard emulator firmware in communication with the keyboard interpreter firmware for reconstruction of the keyboard data for communication to the controller.
