Abstract
To convey parity checking information in a digital transmission system a predetermined digital word is replaced at the transmitter by a unique digital word having the same number of bits which is not allowable in the normal digital stream. The unique word is recognized at the receiver as indicating a particular parity condition. No extra capacity or higher digit rate for the digital stream is required for the parity checking information.
