Title:
METHOD OF AND DEVICE FOR SELECTIVELY COUPLING INPUT*OUTPUT TERMINAL UNITS
Document Type and Number:
Japanese Patent JPS5573159
Kind Code:
A
Abstract:
A system (50) for selectively coupling to an input terminal (52), eg a teleprinter to any of a plurality of transmission lines (54,56,58,60) eg Private line, Direct distance dial line, telex line or TWX line respectively, having different transmission speeds and characteristics is provided. The system (50) includes decode circuitry (74,76) to selectively couple the input terminal (52) to any one of the transmission lines (54,56,58,60). An electronic digital processor (64) eg a microprocessor is responsive to input address signals generated from the input terminal (52) for being operated under the control of stored application programs (70) for causing the decode circuitry (74,76) to couple the input terminal (52) with an addressed one of the transmission lines (54,56,58,60) for transmission of data thereover at the transmission speed associated with the addressed transmission lines (54,56,58,60). The processor may provide storage (68) for incoming and outgoing data, editing facilities and ciphering for secure data transmission.
