基于PRI接口的集中录音方式的应用

The Application of Centralized Recording Method in Power Communication System Based on PRI Interface

基于ISDN的PRI接口在电力交换专网得到广泛应用,通过PRI接口实现集中录音功能既可以调高录音质量还可以提高录音系统的可靠性。文章通过MDR2000N录音记录仪与Coral交换机之间实现PRI接口集中录音的实例,说明了集中录音的实现原理和过程,并对实施过程中出现的主要问题进行了分析和说明,对基于PRI接口的集中录音方式在电力通信中的应用具有一定的借鉴作用。

PRI interface based on ISDN has been widely used in power communication network.The centralized recording,which is functioned through PRI interface,can improve the quality and reliability of recording.Based on the example of practical application of PRI centralized recording between MDR2000N recorder and CORAL exchange,this paper introduces the principle and procedure,and analyses the main problems appeard during the implementation,and gives out the solutions.It has reference value for further application.
