【摘要】 本文的主要工作是设计和开发Windows 2000操作系统下基于USB接口的ISDN通信终端适配器CAPI驱动程序，该驱动程序符合WDM编程模型，支持CAP I2.0和USB规范。论文对WDM编程模型、USB接口标准和CAPI 2.0规范进行了深入分析和研究，提出了CAPI功能与WDM设备驱动相融合的程序设计方案，并完成了具体编程实现。本文介绍了WDM驱动程序的架构，详细的论述了驱动程序中IRP的交互机制，并对程序中CAPI功能模块的具体实现作了阐述。驱动程序支持访问Internet的所有应用软件(WWW浏览器、CuteFTP等)以及现有的符合CAPI规范的用户应用软件(如RVS-COM)，加载该驱动程序的ISDN USB TA除了可以以基本速率(BRI)接入Internet之外，还可以向ISDN用户提供CAPI 2.0规范所支持的电话和传真通信等功能。更多还原

【Abstract】 This paper describes how to realize the design of a COMMON-ISDN-API (CAPI) driver for ISDN Terminal Adapter based on USB interface. The driver accords with Win32 Driver Model (WDM), CAPI 2.0 and USB standard. In this thesis, the analysis and research on WDM, USB Bus and CAPI 2.0 standard are implemented. At the same time, a scheme is provided which combines CAPI with W7DM and the program is implemented. The paper deals with the architecture of WDM driver. The IRP interaction mechanism of the driver and the implement of CAPI function module, which plays an extremely important role in the scheme, are also discussed in the paper. The application software access to Internet, such as any WWW browser, CuteFTP, and so on, and the application program which according with CAPI are all supported by the driver. ISDN USB TA driven by the driver can not only be used to access to Internet, but also supply the communication of telephone and facsimile.更多还原
