And in the early 1990 ‘ s , bell labs was a leader in technology for connecting optical communications rings to one another 在90年代早期，贝尔实验室在光通信环网互联技术方面处于领先地位。
In addition , atm cells are transmitted in the sdh ring network , with bandwidth shared by all node elements on the ring 另外， atm信元在sdh环网中传输，其带宽由环网上的所有节点单元所共享。
Although most token - ring networks operate well below capacity , the day will soon come when applications push them to their limit 虽然多数令牌环网在未满负荷情况下却工作得很好，但应用将把它们推到（满负荷）极限的日子不久就将到来。
The combination of high bandwidth and 100 % channel availability will make it feasible to handle these types of applications in a token - ring environment 高带宽与100 %的通道可用性相结合将使在令牌环网环境中处理这些类型的应用得以可行。
The park is located near the yantai and longkou electricity grid . there are two 35 kva transformer substations with the transmission capacity of 30000 kva 园区临近烟台、龙口两大电网，环网供电。现有3 . 5万伏变电站2座，输变电能力3万千伏安。
Since both full - duplex and classic token ring use standard token - ring frames , the application code that runs on classic token ring will run on dtr 由于全双工和标准令牌环网使用标准的令牌环帧，运行在标准令牌环网上的应用程序也能在dtr上运行。
The problem of finding optimal diameter double loop network with a fixed number of vertices has been widely studied by graph theory and computer science researchers 摘要找出给定顶点数的双环网的最小直径是图论和计算机工作者重点研究的问题之一。
In order to keep the reality of all information , sinodo . com requires all the publishers to supply the scanning photocopy of id or passport to us 为了保证网上信息的真实性，地环网要求无论货主还是货代，发布者必须提供身份证或者护照的扫件，不便之处敬请谅解。
Zte will provide armentel , the country ' s largest telecoms operator , with a new network based on zte ' s end - to - end cdma450 wll ( wireless local loop ) solution 中兴公司将为亚美尼亚电信公司，该国最大的电信运营商，提供首个基于中兴端到端的cdma450无线本地环网解决方案。
This paper introduces using project of industrial ethernet - ring of hirschmann inc . apply on automation ethernet and adapt the manufacture requirement of modern sleel - making plant 介绍了利用赫斯曼公司的工业以太环网方案,在炼钢厂自动控制网络中应用,很好地适应了现代化炼钢企业工业生产的要求。
