Abstract
A FIFO store for data packets and their respective status words includes space for the writing of a predetermined sync word or one of a cyclic sequence of predetermined sync words with each status word. The sync word can be used to prevent forwarding of a packet and as an aid to fault diagnosis if on reading the status word the sync word does not match any of the predetermined sync words.
