Design And Implementation Of The Highway Network Communication System Based On SDH Technology

The highway is the inevitable product of the country’s rapid economic development,highways as a modern transportation infrastructure, and its construction inevitablemonitoring, fees and other ancillary facilities, including roads, these ancillaryfacilities installed across the highway, in order to facilitate unified management, theformation of unified data center on the highway on the information you need totransfer summary, which requires the highway of cation systems, transmission ofbusiness on the highway, the highway network to form an intelligent, so it is bound,ultimately, high way ommunication system, ation system is the highway an importantfoundation support systems, safe, reliable, perfect and efficient communicationsystem is an important guarantee for the normal operations of the highway. It is themain carrier of various traffic information transmission, the communication system isaccurate and timely mission of data, voice and image information such as monitoringsystems and toll collection system, to maintain the smooth flow of highwaycommunications between the communications sites, and highway both internally andexternally to establish the necessary contacts to provide the transmission channel.With the country’s western development efforts have been stepped up, Xinjianghighway ction has entered a period of rapid growth, the vast territory of iang, theconstruction of the highway with regional characteristics, to achieve the Xinjiangnetworking and nications will take some time, this article national ts to achieve thenetworked unications environment, Xinjiang under construction Guozigou of sectionsof length of146km of trunk road communications network design. Xinjiang highwayconstruction early PDH transmission technology, transmission technology continuesto evolve, the SDH transmission network with its own network advantages aregradually replacing the PDH transmission network, the SDH transmission network isthe compatibility of the PDH network, ansmission performance far superior to thePDH network. In this article, the SDH transmission technology, according to the data of this highway business needs, the ment of SDH STM-16level as the core transportbackbone layer and convergence layer and STM-4rating attached to the transmissionnetwork. The ation of the site according to the various communication and datatransmission business, the communications network is divided into the core layer,convergence layer and ccess layer, and each layer of the concrete realization of thedetailed design. The core layer is mainly transmitted STM-16level of particulatebusiness, MSTP networking technology. Convergence layer and access layergrade-based STM-4transmission, data and image transmission design. Data servicesfor ommunications systems to achieve network official business, the network clocktracking the implementation and network protection mode described in detail.Establishment of communication networks, and ultimately, the inevitable test ofnetwork performance, article, the BER performance of the communication networksystem, jitter and wander the main performance indicators of performance, channelprotection switching and grounding performance test, all test results are in line withthe ITU-T prescribed performance standards.In this paper, the design of communications network is also scalable, completebackward compatibility and forward compatibility. More types of the section of thetransmission business, but little traffic and highway critical sections with the rapiddevelopment of highway information, process monitoring, to improve the level ofinformation technology on the existing business to increase other data services, whichrequires the existing communications network, reserved good data capacity is fullyreserved for data transmission capacity of the business, to reserve space for futureexpansion, and make the network flexible and scalable performance. The end of thisarticle part of the communication network is to do a summary.
