摘　　要：对于承担大量交换业务的程控交换机节点,过多使用2 M中继接口,会过度占用机房的空间资源和设备资源,也会增加维护难度。针对这一问题,文章分析了采用155 M中继接口的优点,并探讨了甘肃电力程控交换网采用155 M中继接口的可行性。Using a large number of 2 M interfaces for exchange services at program controlled exchange nods will waste limited equipment resources and cause some problems in maintenance. This paper analyzes the advantages of using 155 M interfaces as digital truck, and discusses the feasibility of using 155 M interface in Gansu electric power program controlled exchange network.
