| Along with the telecommunication service in the wide band data service fast development, the development which the IP service progressed by leaps and bounds in particular, the exchange technology which the telecommunication network used already has the very sweeping change:The traditional electric circuit exchange technology speaking of by the burst characteristics data primarily service, the transmission cost and the exchange cost are high, the efficiency is low, has the network resources waste as well as must use complex shortcomings and so on signaling, cost and network management, already could not meet the high speed data communication application need.In2011,my area IP backbone network, the wireless core network as well as the big customer specialized will have massive10G, the2M electric circuit demand, but the existing electric circuit has not been able to meet this part of electric circuit need, therefore will have carries on the dilatancy construction to my area two level of skeleton line DWDM system and the SDH system.This article altogether has five chapters, in the first chapter of outline first introduced the Inner Mongolian long-distance transmission network construction project background, as well as the long-distance transmission network uses at present transmission technology; In second chapter multianalysis Inner Mongolia area long-distance transmission network at present present situation as well as existence question; The third chapter detailed team in2011the long-distance transmission network service demand has carried on the analysis; Fourth chapter described in detail in2011in the Inner Mongolian area the long-distance transmission network construction plan, as well as in the construction process exists question; Fifth chapter mainly aims at in2011the long-distance transmission network the construction project to appraise that, has analyzed the effect from the technical angle which the project completes achieved. |
