地铁通信民用传输系统浅析

传输系统是一个基于光纤传输的宽带综合业务数字网络,为传送语音、数据和图像等各种信息提供传输通道.传输系统具有集中维护管理功能,采用简明、直观的维护管理界面和系统安全机制,监视每个传输节点主要模块和用户接口的工作状态,并提供声、光报警以及告警信息的打印功能.为了更好的建设民用通信系统,需要更详细了解其基本原理及功能.

Analysis of transmission system of metro civil communication

Transmission system is based on the broadband integrated services digital network optical fiber transmission, transmission channel for the transmission of voice, data and image information. Transmission system with centralized maintenance management functions, the brief, security mechanism and management system interface intuitive, monitor each transmission node main module and user interface work status, and provide sound, light alarm and alarm information print function. In order to construct the civil communication system better, require a more detailed understanding of the basic principle and functions.
