摘　　要：随着网络业务的不断发展,电力通信网络中SDH设备已经无法满足其高带宽、IP化的需求。针对该问题,提出采用OTN设备与PTN设备联合组网的规划,并根据不同地理位置地市的不同需求,提出三种组网方案。其中以OTN组网汇聚层、核心层,PTN组网接入层,经汇聚节点后接入环分散汇聚的方案泛化性最高,适合大部分地市。With the continuous development of network services,SDH devices in power communication networks have become inadequate for the demand on high bandwidth and IP.To solve this problem,this essay puts forward the planning of joint construction of networks using OTN and PTN equipment.According to the different needs of cities with various geographical locations,three kinds of networking schemes are proposed,in which the scheme using OTN to form aggregation layer and core layer and using PTN to form access layer through the aggregation node after the access ring decentralized aggregation,has the highest generalization and is suitable for most cities.
