摘　　要：利用模拟方法分析和研究了恒定比特率和变比特率语音业务信元迭加流的特性．结果表明：当输入话务量Ａ≥６００Ｅｒｌ时，恒定比特率语音业务信元迭加流可近似认为是泊松流；当输入话务量Ａ≥８６Ｅｒｌ时，变比特率语音业务信元迭加流可近似认为是泊松流．A simulation method is presented to analyze the characteristics of the flows.The result shows that the superposed voice flows of CBR voice service can be approximately considered a Poisson flow when the intensity of input traffic is not less than 600 Erl and that the superposed voice flows of VBR voice service can be approximately considered a Poisson flow when the intensity of input traffic is not less than 86 Erl.
