BackgroundReason:We want rehome 50 site 3G at Sanggau area from RNC Pontianak to new RNC Sanggau due to capacity RNC Pontianak already overload.RTN is the main backbone for carrying traffic RNC Sanggau IUPS , IUCS, IUR and OAM also IUB, Abis , and GB with total capacity 680 Mbps.below its the topology of RTN link and the configuration

The following nine groups of colors are an example of how our design colors can be used, please take note that you should only use one design color group per slide. For specific usage details, refer to the Typesetting Standard.Based on technical experience if we use RTN as a Link Backbone for carrying IUPS traffic we cant using LAG configuration because this configuration cant make balance traffic on each member of LAG. So Before rehoming activity we must do an activity below

We must change configuration from LAG became PLA (min RTN NE software version is V100R003C03SPC201)Divide became 2 PLA group and make details traffic which carried on each group of PLAGroup 1 = 2x183 Mbps = 366 MbpsGroup 2 = 2x 157 Mbps = 314 Mbps

B. Recomendation

The following nine groups of colors are an example of how our design colors can be used, please take note that you should only use one design color group per slide. For specific usage details, refer to the Typesetting Standard.Rehoming activity done successfully but have problem 3G PDP SR SGSN Pontianak(S1401) decrease due to RAB Assignment failure/ transport failure.

C. Problem after rehoming Activity



----------------

The following nine groups of colors are an example of how our design colors can be used, please take note that you should only use one design color group per slide. For specific usage details, refer to the Typesetting Standard.D. Analysis and investigation we check transmission side at RTN Backbone

We check link utilization using RMON on peak/busy hour because have suspect link congestion du to high traffic of IUPS

* After we check there is no link congestion based on RMON history

The following nine groups of colors are an example of how our design colors can be used, please take note that you should only use one design color group per slide. For specific usage details, refer to the Typesetting Standard.2. We check history alarm all backbone linkAfter we check we found one channel link have intermittent on ODU (suspect frequency interference)

D. Analysis and investigation cont.



----------------

The following nine groups of colors are an example of how our design colors can be used, please take note that you should only use one design color group per slide. For specific usage details, refer to the Typesetting Standard.We check link utilization using RMON for intermittent link

* When link normal the utilization is around 50 65 % but when link have intermittent the link utilization became 98 100 % D. Analysis and investigation cont.

The following nine groups of colors are an example of how our design colors can be used, please take note that you should only use one design color group per slide. For specific usage details, refer to the Typesetting Standard.Change the interference frequency channel with clean frequency. Search using web lct or optix navigator for clean frequency.If get clean frequency please change directly the interference frequency and monitor few days for performance linkIf not get clean frequency please change ODU sub band until get clean frequency (for recommendation ODU sub band we can get from TNP team).E. TroubleshootingF. Suggestions Every activity should have CR (change Request) and must get approval from Technical Expert and CustomerBefore and after activity must inform to NOCAlways coordination with other related technical department ( core engineer, wireless engineer and Datacomm engineer) HUAWEI TECHNOLOGIES CO., LTD.Huawei Confidential Page #Slide title :32-35pt Color: R153 G0 B0Corporate Font :FrutigerNext LT MediumFont to be used by customers and partners : Arial
