  2. 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。
  3. In this thesis, principles of data coding for transferring data among different network hierarchies is described, a channel and program management center and a user authorization center are designed, and the integration and application of the system into sdh / hfc network are investigated and implemented

    本文對系統中支持不同網路體系間數據格式的轉換的數據編碼原理進行了描述。設計了該系統頻道和節目管理中心以及用戶授權管理中心的構架，並對高速數據廣播系統在sdh hfc網路中的集成和應用進行了較為深入的研究。
  4. The highway communication system was the information platform of freeway traffic control and management. firstly, the paper analyses the characteristics of freeway communication operation, and studies the freeway buildup - network technology ( sdh, ip, atm, and the integrated network technology ). finally, the paper presents the optimization model of communication buildup - network technology for freeway intelligent controlling and management, and two examples are given

    5 、高速公路通信系統是高速公路交通控制和管理的通信平臺，論文先從分析高速公路通信業務特點入手，深入研究了高速公路通信的組網技術（ sdh 、 1p 、 atm及網路技術的融合） ，提出了高速公路智能控制和管理的通信組網技術的優化選型，並給出了兩個案例。
  5. Initially, pdh was introduced to improve and replace the obsolete analog frequency division multiplex ( fdm ) system. however, it was soon found that pdh had shortcomings such as difficulty in management, high construction cost, limited applications and lack of connectivity standards at the optical layer. thus, in the early 1990s, synchronous digital hierarchy ( sdh ) was introduced in the transmission system

    Pdh最初引入是為了改進和替代老式的模擬頻分復用器系統，但很快被發現pdh管理困難、造價高、應用范圍窄，且缺乏在光層面上的連接標準，因此90年代初期， sdh （ synchronousdigitalhierarchy ）標準被首先引入了傳輸系統。
