摘　　要：文章对支持ISDN BR I、PR I接口,基于ITU-U Q.921、Q.931建议的Q信令系统进行了介绍,对当前国际上流行的专用通信网络Q.SIG(PSS1)信令系统的结构、功能及互联作了相应的论述。文章指出了Q.SIG(PSS1)信令是专为企业网络设计的信令系统。它在全球范围内实现了标准化,在容量不大、网络功能要求又很高的电力调度电话专用通信网中,Q信令系统是当前最为适用的信令系统。Facing the new situation of the rapid development of SDH optical transmission network in the Electric Power System, the signaling system is getting more and more important. This paper describes the Q. SIGnaling system for ITU-U, and the structure, features and interconnections of the private communication network Q. SIG/PSS1 signaling system are also discussed, which is widely used around the world at present. After testing, it shows that Q. SIG/PSS1 system is adaptable to the switching telephony communication network in Electric Power System.
