本文提出了一种支持话音/数据综合的交换技术——组合电路交换技术。这是一种改进的电路/分组混合交换技术,它以现有的数学程控交换机和数字时分多路传输系统为基础,根据话音业务和非话数据业务的不同特点,用实电路交换方式处理话音业务,用虚电路交换方式处理数据业务,并将两者有机地结合起来,实现话音/数据综合。 This paper presents a switching technology that supports voice / data synthesis - combinational circuit switching technology. This is an improved circuit / packet hybrid switching technology, which based on the existing mathematical program-controlled switches and digital time division multiplexing transmission system, according to the different characteristics of voice services and non-voice data services, using real circuit switching voice Business, deal with the data business with the way of the circuit of the imaginary circuit, and combine the two organically, realize the speech / data synthesis.
