摘　　要：随着电力通信业务IP化趋势的不断发展,分组传送网(Packet Transfer Network,PTN)逐渐被广泛采用,但是对于分组传送网对E1业务的承载性能,目前仍存在较大争议。文章以分析、评估PTN网络对E1业务的承载能力为出发点,通过原理分析、实验室测试等方式,验证了PTN网络对E1业务的优良承载性能,为未来电力通信网络建设和工程设计提供了新的参考和可靠的依据。With the development of IP-based power communication service, the technology of packet transport network（PTN） is being widely used. But the carrying capacity of the PTN for E1 service is still an argument. In order to analyze and evaluate the carrying capacity of the PTN for E1 service, this paper verified the PTN had a good performance on carrying E1 service by analysis and testing. The conclusion provides a new reference for the construction and engineering design of power communication network in the future.
