Title:
METHOD OF PROCESSING CODED INFORMATION
Document Type and Number:
Japanese Patent JPS5549096
Kind Code:
A
Abstract:
Thirty telephone channels are time-division-multiplexed for transmission and reception in a PCM 30 transmission system. The control- and switching-signals of the thirty telephone channels (e.g., dialing pulses, busy signals, dial tone signals, etc.) are converted from the form of ordinary D.C. currents to an encoded form which the time-division-multiplex system can process. The processing of all the control- and switching-signal data is performed during computing time intervals of a time frame which has been subdivided into computing time intervals in real-time using a control logic which cooperates with a data storage, the control logic being comprised of programmable and permanently wired functional circuit stages. The selection of a particular program from those programmed in such functional circuit stages is performed in dependence upon the significance of the control- and switching-signal information being processed.
