本文根据HFC网模拟、数据多业务接入的发展需求,提出了一种A/B双平台的光接收工作站构造TAB2000。在这个平台上既可以完成CableModem双向数据接入,也可以由5类线实现Ether-net计算机网的接入。同时在这个平台上非常巧妙地利用IP通道,依据SNMP标准网管协议将AB两个网管系统统一了起来,解决了HFC网网管的通用性问题,又简化了传统HFC网网管系统的复杂性,使网管系统更加稳定。研究和实践表明TAB2000双平台光工作站特别适合于城市网的多业务接入。
According to the development demand of HFC network simulation and data multi-service access, this paper proposes an A / B dual-platform optical receiving workstation to construct TAB2000. CableModem two-way data access can be completed on this platform, but also by five types of lines to achieve Ether-net computer network access. At the same time, this platform is very clever use of IP channels, according to SNMP standard network management protocol will AB two network management system unify up to solve the HFC network management of the common problems and simplify the traditional HFC network management system complexity, so that Network management system more stable. Research and practice show that the TAB2000 dual-platform optical workstation is particularly suitable for multi-service access in urban networks.
