EPON+DSL技术在县级地震信息节点的应用

Application of EPON+DSL technology in seismic information service node

介绍了EPON技术及EPON+DSL模式,结合河北省地震局网络传输模式及县级信息服务节点主要存在的问题,以新乐地震台实际改造方案为例,用EPON+DSL新型组网模式对原ADSL+VPDN组网模式进行改造。通过改造后的试用,发现线路故障发生率明显降低。因此,新乐地震台的改造方案可以为河北省地震监测网络其他信息节点的改造提供借鉴。

The EPON technology and EPON＋DSL mode are introduced in this paper. Combined with the network transmission mode of Seismological Bureau of Hebei province and the main problems of information service nodes,taking the reconstruction proj ect of Xin-le seismic station as an example,in which the original network with mode adsl＋vpdn was transformed with the mode epon＋dsl.The trial operation shows that the failure of the net-work line is significantly reduced.Therefore,the reconstruction proj ect of Xinle seismic sta-tion provides a reference for the reform of Hebei Province earthquake monitoring network in-formation node.
