摘　　要：综合业务数字网(ISDN)是综合数字网的延伸,它打破了传统电话网和数据网之间的界限,扩展了网络业务的使用类型和范围。本文指出了传统的通信网的随路信令不能控制和处理ISDN多种数据业务的原因,并从ISDN用户接口部分(U-NI)和网络接口部分(NNI)的LAPD和SS7(ISUP)信令的工作原理出发,使用七号信令分析软件分析了这两种公共信道信令(共路信令)控制ISDN业务传送的过程,得出了运用这两种共路信令是支持和提升ISDN通信性能的必然趋势的结论。As extension of IDN network, ISDN has broken the ambit between the traditional telephone network and data network, expanded the application types and scope of network operation. The article points out the reason why the Associate Channel Signaling can not control and handle the ISDN multi-data operation, analyzes with the Software of No.7 singnaling Analysis the process of controlling ISDN transmission by Commonality Channel Signaling, using the LAPD Signaling in UNI and SS7（ISUP） Signaling in NNI, and draws the conclusion that it is a certain tread to use the two signaling to sustain and upgrade the ISDN communication capability.
