Abstract: ADSL is a common residents broadband access way.Because of its end-to-end communication structure，the traditional surveillance technology is not suitable.Analyzing of the ADSL technology communication structure and data load mode，an outage type surveillance gateway is designed and realized.This paper describes the structure and the hardware implementation，and analyzes the ADSL driving and protocol analysis，IP data extraction process in detail，and the user’s network traffic is online intercepted.
Key words: Asymmetric Digital Subscriber Line（ADSL）, Asynchronous Transfer Mode（ATM）, online interception
摘要： 由于ADSL端到端的通讯结构，传统的监听技术很难适用，详细分析了ADSL技术的通讯结构和数据承载方式，设计了一种ATM模式下的断线接入式的监听网关，描述了网关的结构及硬件实现，详细分析了ADSL套片驱动及协议解析，IP数据提取的过程，实现了在不影响用户网络使用的情况下提取网络层数据的功能。
关键词: 非对称数字用户线路（ADSL）, 异步传输模式（ATM）, 网络监听
