Board Description(1/1)
APZis the Central Processor of the BSC and the executive is
running on it.Also called CPUB-A,CPUB-B.MAU Maintenance
Unit board which controls the Switch Over.
APGis a processor with a Hard Disk and you login to this from
Local maintenance Terminal. From OSS you directly login to
the APZ where the executive is running. All the database and
backup files ,raw counters, command/user logs are stored on
this card.

Board Description(1/2)
EPB(Evo Processor Board)is the capacity defining card for
the BSC like CCP+GPU+MT120 in case of Alcatel and
SPU,DPU,XPU in case of Huawei, all the functions like
transcoding,CS and PS traffic is handled by this card.One
EPB card has 2 processors with 8 cores and they work in
N+1 redundancy. Out of the 8 processors 7(RP regional
Processors) can be used for equipage and 1 is left alone as
central processor. But the redundancy is achieved on the
processor level not on the board level.EPB handles the CTHand GPH(CS,PS)you can configure one EPB for both CS and
PS.

NWI-ENetwork Interface Ethernet Switch which is the interfacebetween BSC LAN and Operator side LAN.It is the switch withprovides GE interface for SIGTRAN,A/IP,OOS,GB/IP
Evo ET (Evo Exchange Terminal) is the interface card used tohandle TDM traffic for Abis Chains. Yellow fibers in the above
snaps depict the Abis STM that are terminated on the ODF. SCXBSwitch Control board is used to carry node internal control
traffic and clock distribution. It is also used for connection withthe slave sub rack. There two SCXB cards per Sub rack work inMaster and Slave
CMXBComponent Main Switching Board provided the 10Gbpsconnections for the user plane traffic. The board works in 1+1redundancy

BSC Logical Connectivity(1/1)
Multiple VLAN are required for the BSC IPconnectivity. Some VLANs are for BSC internalconnectivity with the different boards andinternal processes and applications. The internal
VLAN uses 192.168.x.x IP range. For logging onto the BSC through the
LMT(WinFOIL),you use the following settings
System IP 192.168.200.2
Subnet mask 255.255.255.0
BSC IP 192.168.200.1
