产品描述
本系列设备采用大规模FPGA设计,提供1个光纤接口接口和1个以太网接口与2个串行接口,能够实现10/100Base-T以太网数据在光纤通道上的传输,是一种高性能、自学习式以太网桥。设备内置环路测试功能,为工程开通和日常维护提供便利。
功能特点
◆ 基于自主知识产权的集成电路;
◆ 设备能管理到远端设备的状态, 网管数据不占用用户业务时隙;
◆ 可以在本端强制让对端设备的速率跟随本端;
◆ 可以检测到光纤有没有环回,并通过指示灯指示出来, 并在环回时不往以太网口发送源MAC地址与目的MAC地址相同的包,防止交换机死机;
◆ 以太网支持超长包,最大包长度支持到2036字节(包括CRC32的4个字节);
◆ 内置动态以太网MAC地址列表(4096个),具有本地数据帧过滤功能;
◆ 以太网接口10M/100M,全/半双工完全自适应,支持VLAN协议;
◆ 以太网口支持AUTO-MDIX(交叉线和直连线自适应);
◆ 内部有以太网数据监控自动复位功能,不会死机;
◆ 机架式设备网管接口采用SNMP;
◆ 串行数据接口可以是RS232/RS422/RS485/TTL中的任选一种;
◆ 串行数通道可以传输异步从300-19200波特率自适应的串口数据
◆ 本端可以命令远端的RS232串行数据向本端环回,此环回在RS232数据接口的外环,可以测试RS232的接口芯片有没有损坏
◆ 串行口接口防雷达到IEC61000-4-5 (8/20μS) 差模:6KV, 阻抗(2Ω);共模:6KV,阻抗(2Ω) 标准
◆ 能与以太+2RS232转E1-----E1光纤MODEM-----本设备 联接成三点网络
