西门子已为模拟调解调器开发出一种新型的软件可编程前端器件,这种器件能使设计者为所有各国国内电话标准建立单一的硬件解决方案。与由多个分立的元件组成的传统调制解调器不同,这种Alis(模拟线路界面解决方案)是一种高度集成的硅解决方案,它将一个完全可编程的DAA和一个带有互感器、混合集成电路和Ring Detect(振铃探测)功能,以DSP为基础的编码译码器结合到一块干净而简单的双芯片上执行。由于高水平的集成和软件可编程性,Alis为各种广泛
Siemens has developed a new type of software programmable front-end device for analog modem that enables designers to create a single hardware solution for all national phone standards in all countries. Unlike traditional modems consisting of multiple discrete components, this Alis (Analog Line Interface Solution) is a highly integrated silicon solution that combines a fully programmable DAA with a hybrid with transformer, Circuit and Ring Detect function, the DSP-based codec is combined into a clean and simple two-chip implementation. Due to its high level of integration and software programmability, Alis is wide-ranging
