Abstract
A microprocessor operated telecommunications interface for connection to a telecommunications line to provide transmission of data between a dedicated terminal of an automatic teletypewriter switching service of the type operating in one code and a data base of the type operating in another code is disclosed. The interface includes a microprocessing unit, a memory for operating the microprocessing unit, a random access memory, a telecommunications modem, means for formating and controlling serial a synchronous data communication and at least two user-actuatable switches for selecting a function of the interface. One function selecting switch accesses the microprocessor unit to the user terminal to provide for entry and editing of message information while a second function selecting means actuates the telecommunications to dial the data base using dialing information stored in the random access memory. The interface is an addition to a conventional terminal of a teletypewriter switching service which permits the terminal to be used for purposes other than those for which it is intended.
