Abstract

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.
