Speech transmission capacity of standard ethernet systems

This paper is concerned with the estimation of the speech traffic capacity of a standard ethernet system by simulation techniques. The particular interest in this work is the possible trade-off of speech coding rate against number of simultaneous users during peak traffic conditions. The results of simulation studies are given and it is concluded that the decisive factor in such a trade-off is the maximum transmission delay which may be accepted and also the percentage loss of transmitted information which occurs as a result.
