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。
