摘要
EPON+ADSL这种新型的组网模式,是在新业务不断演进,带宽需求不断增加,以及"光进铜退"的大背景下提出的。采用这种组网模式,能够满足用户需求,节省运营商投资,保证收益。语音质量是各类通信模式下的重要问题,在EPON+ADSL模式下也是如此。文章在介绍了EPON+ADSL这种模式的基础上,对影响其语音质量的因素进行了深入的分析,为提高该种模式下语音质量的研究提供了一定的参考。
With the evolution of the new services and the continuous demands of the bandwidth and under the background of ＂fiber instead of copper＂, EPON＋ADSL, a new-style networking model, is put forward. This model can satisfy the users＂ needs, save the investment of the operators and ensure the benefits. Voice quality is an important issue under the EPON＋ADSL model. This paper introduces the model, does an in depth analysis of the factors which influence the voice quality and provides some reference for the relevant research.
