产品描述
8E1(75/120欧)转光以太网接口转换器采用反向复用技术,将多条E1电路捆绑起来用于传输3路百兆电以太与1路100base-FX的以太网数据,实现了1-8路E1通道至以太网接口之间的相互转换,实现E1信道与以太网的互连。以太网封装采用GFP封装,支持LCAS和LAPS。
本设备支持1至8路E1(75/120欧)信道的灵活配置,能自动检测E1的数量并选择可用的E1,并且允许E1电路之间存在一定的传输时延差。单路线路速率是1984Kbit/s,8路带宽可达15872Kbit/s.
功能特点
◆ 基于自主知识产权的集成电路;
◆ 实现以太网数据在1~8条E1电路中的透明传输;
◆ 能实现对本端、远端设备的复位操作;
◆ 4路E1线路中,任意两路之间的最大延时差可达220ms;当延时差超过时,将会产生延时差超限告警,同时业务中断;
◆ 以太网接口100base-FX支持VLAN协议;
◆ 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;
◆ 单路E1线路速率是1984Kbit/s,8路带宽可达15872Kbit/s。
◆ 可选本地定时和跟踪E1线路定时模式,E1线路定时源可以根据信号质量自动切换。如系统的E1 线路定时源为第一路E1;
◆ 符合ITU-T标准协议,GFP-F 封装建议G.7041,VCAT 虚级联和LCAS链路容量调整方法建议G.7042,Ethernet到nxE1 映射建议G.7043,Ethernet 至单E1映射建议G.8040;
◆ E1接口符合ITU-T G.703、G.704和G.823,不支持信令时隙的使用;
◆ E1接口模块含有内置的时钟恢复电路和HDB3编解码电路;
◆ 设备工作中支持E1信道的热插拔,并自动检测有效的E1信道,中间不会中断数据传输;
◆ 支持1至4路E1的灵活配置,在复位时自动检测E1的数量和时延并选择可用的E1;
◆ 可以组成以太网E1网桥(A)---光以太网E1网桥(B)---以太网光纤收发器(C)的拓扑结构,能在A端管理到B点与C点;
