一种新型调度电路连接方式

New type connection mode of dispatching telephone circuit

对目前的调度电话电路的连接方式进行了分析,指出改电路方式存在的问题,通过理论分析,试图减少其中的部分电路环节,构建出一种新型调度电路连接方式。在具体操作中,利用调度程控交换机中的数字中继电路(E1)可配置信令功能,结合现代SDH设备的交叉连接技术,实现了一种新型调度电路交换传输模式。文章介绍了此连接方式的实现条件、实现方法及使用效果,并对此方式在电力通信行业中的应用进行了分析。

The article analyses the connection mode of dispatching telephone circuit in common use, points out the existent problems caused by this mode, and through the theoretic analysis tries to reduce part circuit of this connection mode to build a new type connection mode of dispatching telephone circuit. In the course of practice, by making use of the function of configurable signaling of digital trunk unit （E1） in the switch and by associating with the technology of cross-connection in SDH equipments a new type switching and transmitting mode of dispatching telephone circuit is realized. The article gives the condition and methods to realize this connection mode, and proves that the mode can reduce some parts of circuit and improve the quality and reliability of calls. In the end. the article discusses the application of this mode in telecommunication for electric Dower system.
