該項目中，本人完成了以下幾方面的工作： （ 1 ）負責所有消息的驅動，使上層應用程序能夠接收到底層硬體設備產生的消息，並做相應處理； （ 2 ）負責所有硬體驅動程序的設計和調試。驅動程序包括lcd顯示驅動、 flash驅動、 e ~ 2prom驅動、聲音驅動、 gsm模塊狀態監控驅動、鍵盤驅動、串口驅動、實時鐘驅動、電源管理、摘掛機檢測驅動，共10部分。 （ 3 ）負責解決遇到的所有與驅動相關的問題。For recent years, adsl has world widely employed and widely used in many aspects such as vod, remote medical treatment and e - shopping etc. but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals, and the adsl ' s frequency rang is from 0 to 1. 104mhz, so we must confront the signal attenuation, the loop line noise impairments, the crosstalk interferences, the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks
近幾年來， adsl在世界范圍內得到充分的使用，廣泛應用於視頻點播、遠程醫療、網上購物等各個方面。但是由於電話線網路是專門為傳輸低頻信號而設計，而adsl的頻譜范圍在0 1 . 104mhz內，因此在傳輸adsl信號時，面臨著信號衰減、線路噪聲、串音干擾、橋接抽頭反射和射頻干擾等等多方面的問題，這就要求在adsl開通之前對線路進行一系列的測試。Connectors for electronic equipment - test and measurements - test 25a - crosstalk ratio
