华为交换机号码变换的灵活应用

Flexible Application of HUAWEI Switch Number Transformation

CC08交换机是固定电话交换机中功能强大而完善的一种交换机,其中很多原理和应用在软交换中仍然延续。随着业务的发展,可通过号码变换改变号码显示方式和位数、改变计费方式、改变话单显示号码等,以满足电信网络灵活组网的要求和特殊用户的特定需求。日常维护中,交换机通过号码准备、主叫号码分析、号首处理、中继承载等实现号码变换。由于不同号码变换方法原理不同,对网络产生了不同程度的影响。如何灵活应用和掌握这些功能,是交换维护人员必备的条件。文章从号码变换原理、步骤、实例方面,全面阐述了号码变换的应用。

The CC08 switch is a powerful and perfect switch of the fixed telephone exchange, and its many principles and applications still remain in the softswitch. With the development of business, the number display mode and digit number, the billing model, and the bill number may be converted via number transformation, thus to meet the telecommunications network flexible networking requirements of the telec0m network and special demands of the specific users. In daily maintenance, the switch, via number preparation, calling-number analysis, numbdr--head processing, and relay carrying implement, number conversion. The different principles for different number-transformation methods, would usually exert different influences on the network, and thus how to flexibly apply and master these features would become the essential conditions for the exchange-maintenance personnel. This paper discusses the application of number transformation from the principles, steps and examples.
