摘要
电力系统通信需要提供多种业务的服务,要求电力系统通信网络稳定可靠且具有高效率。SDH体系不仅适用于点对点的信息传输,而且也适用于多点间的网络传输。SDH用户接入设备综合应用于电力系统通信的接入网,不仅保证了电力系统通信业务的高可靠性、高可用性,而且具有大幅度降低工程造价等优点。
Electric power system communication should provides several types of service,and it requires the system communication stable, reliable and high effeiciency. SDH system is not only adapts to the point - to - point transmission, but also to several point transmission. The comprehensive application of SDH user＇s connecting equipment in electric power communication system is not only protects the high reliability and feasibility of electric power communication, but also possesses the advantages of reducing the engineering cost etc.
