Along with the technology mature in the soft switching and media gateway , the narrow band access equipment will be integrated the function of media gateway . users may access directly to the broadband ip man through twisted cabling or wireless base station . dial - up server will also be replaced by the media gateway , narrow band dial - up users will be diverted to broadband ip man at the access network 随着软交换和媒体网关技术的成熟，在窄带接入层设备上将综合媒体网关的功能，用户通过双绞线或无线基站接入后，可以通过媒体网关直接接入宽带ip城域网，拨号服务器也将大量被媒体网关取代，窄带用户拨号上网将在接入网被分流至宽带ip城域网。
After analyzing , it is determined that an embedded - data - monitoring system , instead of the traditional communication card that links the ipc and monitoring center , can be put into practice to directly join together with the switched ethernet control network , so that the user can monitor the industrial field using internet / intranet conveniently 经过分析，决定用嵌入式的数据监视系统取代传统的钢厂薄板工段数据监视系统典型配置中的通信网卡，以便直接接入交换式以太控制网络，用户可以用internet intranet技术监视工业现场，而不仅限于原来的监控室。
