Title: Transmission system for parallel binary coded data - has redundancy code for error detection and fault protection
Inventor: POLLACK WOLFGANG
IPC: H04L1/18
Filed: 1975-01-31
Abstract: A data transmitter (S) is coupled to a receiving terminal (E) via six lines (LSY1). An additional line (LSY2) is used as a return circuit and indicates to the transmitter the reception of error signals. A control circuit (K) carries out a parity check on the incoming data and provides the error detection. The incoming data is fed in parallel to a number of receiving units (EE1), (EE10). Each of 10 inputs has its own redundant information input. The outputs of each receiving circuit are fed to a selector switch. the system provides error-free transmission without the need for a large number of extra data transmission lines.
