一、中继承载功能概述华为 C&C08交换机8K 及以下版本的中继承载(TGLD)功能, 是实现系统对相关主被叫号码进行号码变换的一种方式。中继承载功能之所以不同于系统其他方式的号码变换,是因为在整个系统呼叫处理过程中中继承载功能在系统用户侧的收号阶段就开始对主被叫号码发生相关的号码变换,并且在号码变换后的第若干位开始占用局向中继群中继,即称中继占用点。
I. Overview of Relay Bearer Function The trunk bearer (TGLD) function of Huawei C & C08 switch 8K and below is a way to implement the system to change the number of the related called number.
