FUNCTION CODING SYSTEM VIA DIGITAL ADDRESSES IN A COMMUNICATION SYSTEM

摘要

Increased efficiency in the use of a communications channel between a Control Unit and a multiplicity of terminal or satellite units by utilizing the combinations of the unit address code words and their complements as coded commands and automatically returned responses. At least one combination of the Control Unit address code words and word complements can be manually entered at any one of the satellite units to serve as a special response to one combination of the respective satellite address code words and word complements, to cause a change of function or operation at the Control Unit. The system may be coupled to a Host Computer and normally the information received by the Control Unit would be encoded for transmission to the computer, in which case the change of function could be the disenabling of transmission to the Host Computer.
