CPUB & MAUB
› CPUB – Central Processor Unit BoardMain processor board of the switch.The CPUB board is a more or less a standard PC-board, with a multi core processor, memory, multiple IO-interfaces and a maintenance support processor.
› MAUB - Maintenance Unit BoardThe MAUB implements the maintenance unit function. It interfaces both the CP-sides, the CDU panel and the SCXB.

NWI-E› NWI-E is a Layer2/Layer3 Ethernet switching
plug in unit for the Ericsson GSM/BSC› Enables IP on the BSC external interfaces
A over IP, Abis over IP, Gb over IP› One-slot plug in unit for GEM and eGEM
technologies› NWI-E supports Ethernet/IP functions: static
routing, VRRP, VLAN, ACL…› The front panel interfaces include
– 11 x 10/100/1000 Base-T Ethernet– 2 x SFP supporting both electrical and optical
GBIC for Ethernet– 1 x RS-232 serial management interface, used for
initial installation and for troubleshooting– 1 x 10/100/1000 Base-T Local Ethernet
management interface used for troubleshooting
