摘 要:目前,E1线路作为一种可靠便捷、经济实用的传输手段,已经越来越为用户所接受。但由于E1线路的带宽限制(2Mbit/s),当用户需要同时解决音频、视频、数据、电话、时钟等业务时,变得困难重重。使用一种设备,将多种不同用途的数字信号复合起来通过E1线路进行传输,既可降低设备成本,同时节省通道的占用。对相关实现技术进行了分析,并对已投入运行的系统功能进行了介绍。At present, as a reliable and convenient, economical and practical means of transmission, E1 lines has been increasingly accepted by users. However, the bandwidth limitations (2 Mbit/s) of as E1 lines makes it difficult to simultaneously address the audio, video, data, telephone, clock and other businesses. A method that a device is used to combine several digital signals for transmission is introduced. It can not only reduce the equipment costs, but also save the channel occupancy. And the system functions which has been put into operation are elaborated.
