可見，傳輸配置基本是按照協議層次從下到上配置的順序，先設定物理端口、再劃分VLAN，再配置接口IP地址，然后配置傳輸層端口和應用層的路由數據。Itisclearthatthetransmissionconfigurationisbasicallyconfiguredintheorderoftheprotocolhierarchyfrombottomtotop,settingthephysicalportfirst,thendividingtheVLAN,configuringtheinterfaceIPaddress,andthenconfiguringtheroutingdataofthetransmissionlayerportandapplicationlayer.GNodeB傳輸數據配置GNodeBTransmissionDataConfiguration下面我們學習傳輸配置的MML命令。MML命令包括物理層命令、數據鏈路層命令、網絡層命令和傳輸層命令，我們依次來看看吧。ThenwestudytheMMLcommandsfortransmissionconfiguration,includingphysicallayercommands,datalinklayercommands,networklayercommandsandtransmissionlayercommands,let'stakealookattheminturn.GNodeB傳輸數據配置GNodeBTransmissionDataConfigurationGNodeB傳輸數據配置GNodeBTransmissionDataConfiguration物理層命令Physicallayercommand在這個命令中，重要的參數是傳輸配置模式，選擇為new（新模式）。Inthiscommand,theimportantparameteristhetransmissionconfigurationmode,whichisselectedasnew.1.設置全局傳輸參數：SetGTransParaSetglobaltransmissionparameter這是一個高危命令，紅色為重點參數。槽位號為基站上提供傳輸連接單板的的槽位，即UMPT單板的7號槽位，端口號為1號，即UMPT單板的1號光纖接口，端口屬性為光纖接口；速率為10G，這里需要注意的是光口的速率是由光模塊決定，光纖兩端的光模塊要協商一致。雙工模式選擇全雙工。Thisisahigh-riskcommand,withthehighlightedparametersinred.
