从硬件电路到Api函数调用,详细介绍了七号信令数据发生器的设计与实现。首先,阐述了发生器的硬件组成和主要部件的连接,并进一步给出了硬件电路设计核心部分原理图;然后,讲述在驱动程序中,主处理器(X86处理器)对Link芯片和E1/T1收发器芯片的配置过程;最后,阐述如何调用插入卡的Api接口函数。目前,本数据发生器在生产,测试和研发调试中都得到了很好的应用,更好地体现了本设备的研制价值。 From hardware circuit to Api function call, the design and implementation of SS7 data generator are introduced in detail. First of all, the hardware components of the generator and the connections of the main components are described. The core schematic of the hardware circuit design is given. Then, in the driver program, the main processor (X86 processor) T1 transceiver chip configuration process; Finally, elaborate how to call the plug-in card API interface function. At present, the data generator in the production, testing and R & D debugging have been very good application, better reflect the development of this device value.
