Current issue overview › After integrating the BB5212 in the network with 2G 1800 as MSMM with the DUG we face issue in the 2G “RFperformance” and “RUS re-starting” also same issue faced in the BB5212 › The solution was to have the site synchronized over NGS feature. › We faced some limitations due to complex site configurations which is presented in the below slides. › Issue resolved after making the DUW as NGS master.
