Abstract This paper investigates the optimal packet length for AAL2 packet voice system without bit dropping, which takes into consideration the features and quality of service of AAL2 packet voice. A conclusion is drawn that the optimal packet length is about 31byte for the case of 32kb/s encoded voice when AAL2 packet voice multiplexer without bit dropping is concerned. As far as 16kb/s encoded voice is concerned, the optimal packet length is about 27 byte. Under this condition, good voice quality can be achieved with small packet overhead.
