Hey jawad!

ARINC 629 is half-duplex just a faster format, it transmits in both directions just not at the same time which is the difference between duplex (2 way simultaneous) and half-duplex (2 way-in turns). It has to take turn in either transmitting or receiving. It just does this process quicker than previous half-duplex models (429 & mil 1553b).
