High-speed error-proof data transmission - has microprogrammes for control with parity bit generator and register

摘要

The receiver determines a transmission error by means of parity testing circuits. When there is an error present, an error indication is stored automatically. The defective data element is given a parity corresponding to the defective information by means of a generator circuit. The data block is then transmitted completely and after transmission the error indication is requested by the control microprogramme. When the errors have appeared, the data block is transmitted once more.
