局域网(LAN)互连需求的增加,要求广域网(WAN)使用新技术和设备来更快和更可靠地传送数据.目前很多国家的网络采用帧中继(Frame Relay)技术和E1(2.048Mbit/s)的线路实现网络互连.和其它的新技术一样,在安装与维护这种高速数据通信网时,也会面临许多问题.本文将举例说明如何使用高速规程分析仪帮助您进行故障查找.一般而言,要迅速而准确地解决网络互连的问题,要求WAN规程分析仪至少具有下列功能:验证线路可靠性:传统的方法是进行一系列的在线(in-service)和中断线路的比特误码率测试.误码测试结果可揭示干扰数据业务的物理层的故障.
Increasing demand for local area network (LAN) interconnects requires that the Wide Area Networks (WANs) use new technologies and equipment to transmit data faster and more reliably.Now many countries use Frame Relay technology and E1 (2.048 Mbit / s), as with other new technologies, there are a number of issues that can arise when installing and maintaining such a high-speed data communications network.This article will illustrate how to use a high-speed procedure analyzer to help you troubleshoot. In general, to quickly and accurately solve the problem of network interconnection, require WAN protocol analyzer has at least the following functions: Verify line reliability: the traditional method is to carry out a series of in-service and interrupt the line of bits Bit Error Rate Test The bit error test results reveal the physical layer of the interference data service.
