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.

NGS solution MIX RUS with RRUS 3 DUG case › It was difficult case to troubleshoot as the combination of RBB and DBB was limited during the implementation. › To have NGS path to the Baseband we must follow the previous diagram for the mentioned case (RRUS 1800 +RUS 900) and three DUG › The availability of the 3 DUG’s will make flexibility t select the required RBB and DBB combinations. › As from the next case we have limitations in RBB and DBB combination which prevent us to integrate the site successfully.
