Название (англ.):
Information processing; Use of longitudinal parity to detect errors in information messages
Описание (англ.):
Describes method for error detection in information messages by attaching one block check character to the transmitted information block (or text) and checking this character when it is received. Applicable to systems with 7-bit-coded character set according to ISO 646, and basic mode for implementing this 7-bit code in data communication systems according to ISO 1745. Conforms to rules for generating character paritity bitsaccording to ISO 1117 that parity sense shall be odd in synchronous and even in anchroneous systems.
