摘　　要：目前国内三大运营商都有部署第三方接入型OTN设备(CPE设备)的需求,在接入层实现末端OTN设备解耦以降低客户接入成本,但大规模部署CPE设备时,对CPE设备的DCN网络部署的考虑较少。通过分析CPE设备DCN网络互通的原理,结合现网部署可能遇到的问题,提出不同方案进行分析比较,为CPE设备泛在工程化提供一些经验。At present,the three major domestic operators have the need to deploy third-party access OTN equipment(CPE equip-ment),and decouple the end OTN equipment at the access layer to reduce customer access costs.The deployment of CPE network DCN is not taken a full account while construct CPE network in a large scale.By analyzing the principle of DCN net-work interworking of CPE equipment,combined with the problems that may be encountered in the current network deploy-ment,different schemes are proposed for analysis and comparison,so as to provide some experience for ubiquitous engineer-ing of CPE equipment.
