BTS 3900, BSC 6900/6910 USN9810, UGW9811. CG9812 For Wifi we have AP And the AP controller AC MAG9811 ----------------WA251DK-NE (DK is 2.4/5G integrated antenna!!) TGW: introduce throughput from wifi to PS network Distributed Base station DBS3900 which can be installed on top of building -----DBS3900 scenario: Outdoor, if AC powered, use APM30H If -48V DC, use TMC11H For power conversion, the 110/220V AC is converted in the APM30H by PSU board in to -48VDC Then DCDU distribute power to rfu/rru

The upeu will convert the power into +12V DCDCCU- Direct Current Distributed UnitCPRI connects BBU to RFU and RRUE1: 2.047MbpsT1:1.544MbpsFE: 100MbpsGE: 1000MbpsBBU, RFU and RRUDiscuss usage..We can also see the capacity for each BTS single cabinet. Can hold up to two BBUs for Ver.D Cabinet (show next slide)-----------The boards in this BBU are  .UPEU, which is in charge of the outdoor power flow-------------UBBP is version SRAN9.0 onwardsGUL need 2 BBU= GTMU+UMPT & LMPTBut SRAN8.0 need 1 BBU because UMPT can support 3G & LTE FAN-controls the rotation speed of the fans and monitors the temperature of the fan module.Note: SRAN7.0: UMPT support U or LSRAN8.0 onwards: Different modes share one control boardNote: SRAN 9.0 : BBU interconnection through UMPT+UMPT is supported The U2000 supports various northbound interfaces for performance, configuration, fault, inventory management, and MML by file, SNMP, CORBA, ASCII and command line interface.The U2000 is connected to the NMS to different vendors. For cooperation in OSS field, the U2000 has finished interoperability test with several well-known professional OSS vendors  System Monitoring: Monitor multiple application services of M2000 itself and multiple processes of M2000 serverNE Monitoring: Monitor connection between M2000 and managed NEs-The U2000 provides the dual IP address configuration solution that supports northbound and southbound network isolation, helping ensure security.   Northbound and southbound networks are classified based on the U2000 server.The southbound network refers to the transmission network between the U2000 server and its managed NEs.The northbound network includes northbound interfaces provided by the U2000 for the upper-layer NMS and transmission network between the U2000 server and client, as well as the U2000 server and other Huawei OSS products.M2000 server includes: multi services, processes and one connection between M2000 and one certain managed NEDisplay on M2000 client and storage in M2000 database: Performance counter3-Tier Architecture: User interface/Business logic layer/Data access layerUmbrella system: NMSInfo we need to know to configure M2000Types and versions of physical NEsPerformance period15 min, 30 min, 60 minPerformance data every 60 min or every 15 min requires different hardware capabilities for the M2000.Number of performance countersAll counter modelKPI model Counter increase, same NE more.KPI:1/50 => 50 cells to 1 eNEDifferent number of performance counters can be converted into equivalent NEs of different numbers.OSS is for RAN and PS partATAE: Advanced Telecommunications Application Environment A carrier-class processing platform that is designed to meet the service application requirement of high performance, high specialization, and high integration.MBB: Mobile broadbandusn 9810ECU Signal HandlingEPU Data forwarding of 2G & 3GESU is the combination of bothBy using ESU, able to downsize the cabinet to only 1 cabinet to support the boards while achieving high capacity.USN Mostly handle signalling, less data UGW ONLY DATAATCA platformIn each frame, there are 14 vertical board slots with numbers ranging from 0 to 13 and two horizontal board slot  The OMU is configured in the basic subrack. In the basic subrack, the rear board of the switching unit (SWU) is the time master interface (TMI). In the service subrack, the rear board of the SWU is the time slave interface (TSI).The board area of a subrack has 14 slots at the front and rear sides respectively. Boards can be inserted from both the front side and the rear side of the subrack. The front boards SWU and the corresponding rear boards, TMI or TSI, occupy slots 6 and 7. Other slots, namely, slots 0 to 5 and slots 8 to 13 are the slots for universal services.Two subrack management unit (SMU) and two subrack data manage (SDM) boards exist at the bottom of the subrack. The SMU and the SDM are mutually inserted from the front side and the rear side. The SMU is located at the front side of the subrack and the SDM is located at the rear side of the subrack.ECU & EPU:Basic Subrack: 1.one pair of OMU and SWU should be in basic subrack. 2.The rear board of SWU is TMI.Service Subrack: 1.one pair of SWU should be in service subrack. There is no OMU in service subrack. 2.
