摘　　要：简要介绍lGEPON的网络宽带接入方式,此方式是目前实现语音、数据与视频三网合一的理想方式,对于语音接入主要有VoIP和CESoP两种。提出一种基于ZL50120的ONU语音接入实现方法,采用CESoP方式,能够确保电话业务的服务质量,电话业务接口的技术性能指标满足相关规范要求。重点阐述了基于ZL50120的ONU的软硬件设计方法;电话接口的性能测试结果表明,所提出的方案在GEPON运行良好。Firstly, GEPON which is the Broad Band Access way is introduced, and it is presently able to syncretize voice, data, video, then there is two voice access way such as VolP, CESoP. The paper puts forward a portable design scheme of ONU on ZL50120, which may be implemented by using CESoP, and assures QoS of telephone operation,and telephone operation interface accorded with correlative criterion; How to design and implement the hardware and software of ONU on CS6220 was described;Performance testing result of telephone interface indicated that the design run all right on GEOPN.
