sub ring
解釋
備用舉重臺-
The tandem switch must first be connected to the transmission equipment providing 2 mbs ports and to the transmission equipment in other tandem area via high - speed ( e. g. 10 gbs ) transmission equipment, and then to digital access and cross - connect system ( dacs ). it is further connected to the corresponding sdh sub - ring after the vc - 12 level cross - connection carried out by the dacs and finally reaches the end exchange
匯接交換機首先需要連接到提供2mbs埠的傳輸設備，而後經高速率的傳輸設備（如10gbs ）到達其它匯接區的傳輸設備上，再接入到交叉連接設備（ dacs ）上，經dacs進行vc - 12級別的交叉連接，接到各個相應的sdh子環中，最終到達端局交換機。 -
Chongqing expressway networking toll data communication network cotains 2 - ring and 8 - ray network structure based on expressway physical structure, setting up a trasmission trunk layer of sdh stm - 4 ( can be up - graded to stm - 16 ), and channel protection business entry layer consisting of sdh onu / olt stm - 1 ( can be up - graded to stm - 4 ). data exchange layer, through ip route exchange network above sdh network, forms 3 - level computer network structure of account settlement center - road section management company - toll station. to ensure obtaining original and reliable toll data from communication network, 2m circuitous chain is established between each toll station, accountsettlement center and road section management company, and also pstn dialing backup chain is set up between toll station and account settlement center. in order to maintain clock synchronization of the whole communication network, a proposal of sub - stage clock sychrononization signal network for differet network construction scale has been put forward in this design. in view of sensitivity and importance of toll data, this design particularly gives considerations of network safety and information safety for external and internel of network. therefore, communication safety, smoothness and reliability of networking toll system can be able to maintained in many ways
重慶高速公路聯網收費數據通信網的結構是根據高速公路的物理結構構築了2環8射的網狀結構，建立了以sdhstm - 4 （可升級到stm - 16 ）的傳輸主幹層，以sdhonu / oltstm - 1 （可升級到stm - 4 ）組成的通道保護業務接入層。數據的交換層是在sdh網之上的ip路由交換網，形成了結算中心-路段管理公司-收費站之間的3級計算機網路結構。為從通信網路上保證收費數據的原始性和可靠性，每個收費站和結算中心、路段管理公司之間建立了2m迂迴鏈路，同時在收費站和結算中心之間建立了pstn的撥號備份鏈路。 -
All of them have been verified through the simulation, design and measurement. the main work includes : 1. a monopulse antenna has been designed which includes a hybrid - ring and a 2 2 sub - array
本文主要就一些針對微帶天線提出的新的方案和要求，成功完成了對幾種新的結構的設計、模擬、製造和測試。 -
This system controls the sub - area by road network in closed ring circuit achievement, searches a bunching parameter combination using the signal parameter optimization model, carries on the coordination control to the different closed ring circuits to form chooses in advance the plan, and on the judgment, the choice through system hypothesis surface controlling rate, thus determines the final signal control plan
該系統以路網中的閉合環路作為控制子區，應用信號參數優化模型計算參數組合，對不同閉合環路進行協調控制形成預選方案，通過系統設定的面控率進行判斷、選擇，確定最終信號控制方案。 -
Enlightened by the structures of group and ring in algebra, in this paper, author firstly raise the concept of fuzzy power ring. first, the properties of the fuzzy power ring will be considered. second, the structure of each fuzzy power ring will be described systematically, and attempts will bo made to classify the fuzzy power ring and the chains of sub rings will bo constructed
