ISDN-Objects专门为DELPHI设计并优化。只要用简单的方法（如Connect/Disconnect/Sendfile/ReceiveFile等），你可以立刻在你的程序中加入ISDN的功能。超级的性能也是亮点之一。数字电话文件传输或传真，ISDN-Objects是你更快地开发ISDN应用的理想工具。ISDN-Objects的技术数据：非常简单的方法用以在最快速度下发送和接收数据，在线帮助，无限通道，无限控制器，CAPI 2.0，与ISDN卡生产商武官，编程简单，强大的高层方法（如SendFile / SendWave），支持所有ISDN协议数据压缩（如果CAPI驱动支持，将采用V.42bits），将电话实时转换到WAVE或反之。-ISDN-Objects for DELPHI design and optimization. As long as a simplistic way (such as Connect/Disconnect/Sendfile/ReceiveFile, etc.), you can immediately in your program to add ISDN function. Super is one of the highlights of the performance. File Transfer digital telephone or fax, ISDN-Objects is the faster you develop the ideal tool for ISDN applications. ISDN-Objects of the technical data: a very simple method for the fastest speeds in the send and receive data, online help, unlimited access, unlimited controller, CAPI 2.0, with the ISDN card manufacturers attache, programming is simple, powerful high-level methods (such as SendFile/SendWave), support all the ISDN
