Abstract
The integrity of a signal path through a transmission system (12), which processes successive blocks (14) of data during a given time frame, verified by establishing the parity of a selected one of the blocks as it enters and as it leaves the system. A lack of equality between the parities is indicative of a lack of path integrity.
