The Research on Consistency Testing Technology of 1000Base-T Ethernet physical layer

摘要:

物理层基于网络结构底层,负责网络电信号的发送、接收,当物理层性能状态出现问题时,将严重影响网络设备的通信质量,且故障点难以被发现排除。本文依据《IEEE 802.3-2000和ANSI X3.263-1995标准》对以太网物理层的相关要求,对1000Base-T型网络接口物理层一致性特征信号测试方法进行研究,结合数字示波器高级触发功能设计了能够准确捕获特定特征信号的测试方法,该方法能满足网络物理层一致性测试相关需求。

Abstract:

The physical layer is based on the network structure,which is responsible for the transmission and reception of the network signals.When the physical lay’s performance state has problems,it will seriously affect the communication quality of the network devices,and the fault points are difficult to be found out. According to the "《IEEE 802.3-2000 and ANSI X3.263-1995 standard》 this paper studies the test method of the consistency characteristic signal test of the physical layer of type 1000Base-T network interface,and designs a test method that can capture the specific characteristic signal accurately with the advanced trigger function of the digital oscilloscope.This method can satisfy the consistency test phase of the nerwork physical layer.
