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.

Board Description(1/3)

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
