“第六届国际地铁、轻轨及城市轨道交通展览会”定于6月7日——9日在南京举行,中兴通讯自主开发、专为地铁信息网络设计的ATM综合系统将在此次展会亮相。 在展会现场,中兴通讯将搭建一个地铁信息网络的模型:以2台ATM综合系统为主,模拟控制中心及一个车站,传送图象、数据、话音等业务。车站设2台摄像机,在控制中心进行图像的控制切换与话音的交换。 地铁通信在我国是新兴的专网领域,不断创新的中兴通讯立足成熟的交换、接入、监控与图象处理技术,结合日臻完善的ATM技术,成功开发出集图象、数据、语音通信于一体的ATM地铁专用系统。中兴通讯专为地铁设计的通信网络,包括铁路行车调度及站场轨旁通信设备、接入网、数字图象编解码器及摄像显示、程控交换机、动力与环境集中监控、组合电源、广播系统、时钟系统等,可以高质量实现通信、行车调度指挥、图象监视、设备监控等多种业务,为地
The 6th International Exhibition on Subway, Light Rail and Urban Rail Transit is scheduled to be held in Nanjing from June 7 to June 9 with the self-developed ZTE Corporation’s ATM integrated system designed for the subway information network to be unveiled at this exhibition . At the exhibition site, ZTE will build a model of the subway information network: two ATM integrated systems, an analog control center and a station to transmit images, data and voice services. Station set up 2 cameras, control center in the control of image switching and voice exchange. Metro communication is a new area of private network in our country. With its mature exchange, access, monitoring and image processing technologies, ZTE constantly innovates and integrates the image, data, voice communication One of ATM dedicated system. ZTE designed communication networks designed specifically for the MTRC, including railway traffic dispatching and station yardside communication equipment, access networks, digital image codecs and camera displays, PBXs, centralized monitoring of power and environment, combined power supplies, broadcasting systems , The clock system, etc., can be high-quality communications, traffic dispatching command, image monitoring, equipment monitoring and other business, to
