  • Abstract
    An easy closed form for prediction of the mean bit-rate of one conversation generated by SID-capable speech codecs as a function of the codec and the number of frames per packet used is presented. The predicted mean bit-rate is compared to measured data and to the traditional ON-OFF model prediction, demonstrating the accuracy of the model. Results can also be applied to the output link capacity dimensioning when several homogeneous voice sources are multiplexed.
