MXBSC Hardware MUX(MUltipleXer) is located in E1 shelf, it is the central board managing packing/unpacking E1 frame to/from Ethernet frames. LIU(Line Interface Unit) board is E1 access interface, it is multiplexing and de-multiplexing of 16 E1 to/from two MUX boards NE1oE(N E1Over Ethernet) NE1oE in an Alcatel-internal protocol is designed to encapsulate TDM frame into Ethernet frame to be transferred through internal Ethernet network. It is used to communicate between Mux and TP. It is implemented in a dedicated FPGA chip present on both boards

如果ATCA shelf 安装在 upper位置的话 ，jumper 2要 remove见图b 如果ATCA shelf 安装在 lower位置的话 ，jumper 1要 remove 见图a

MXBSC Hardware SSW(Subrack SWitch) Performing Gigabit Ethernet switching at the shelf level Performing powerful monitoring for user plane and control plane (Gigabit Ethernet on front panel) Ensuring daisy chain with other shelves via two 1 Gigabit Ethernet ports (only one is used) Ensuring Multicast function Allowing several external Ethernet 10/100/1000 Base T connections: OMC-R, CBC, LCS, Debug … Implementing 12 non blocking 1Gigabit Ethernet links via backplane connections.

MXBSC Hardware TPGSM(Transmission Processing GSM) TPGSM supports all the transmission functions (except for LIU access) of MxBSC including user plane transmission, signaling and TDM switching. Gigabit Ethernet switch NE1oE Multiplexing/de-multiplexing of up to 252 E1 TDM switch Handling of low layers of GSM protocols

MXBSC Hardware CCP(Call Control Processing) The CCP is in charge of the telecom control of the MxBSC. This is a general purpose processing board based on ATCA technology. OMCP(O&M Control Processing) The OMCP is a variant of CCP board equipped with large capacity storage (in a disk). It is in charge of the O&M control and partial telecom (TCH_RM) functions.

通过JAXPC 板来设置 ATCA shelf 的位置: S2:设置成0 S1:设置成3 即shelf 3 设置成4 即shelf 4

MXBSC内部VLAN
MXBSC与OMC-R的连接方式：

MXBSC内部VLAN
MXBSC内部的3 VLAN： VLAN1 : 用于MXBSC内部消息的通信.即：CCP板子之间,OMCP/CCP 之间 传送消息；以及OMCP与NE1OE模块之间的O&M控制。 VLAN22: 外部O&M traffic (SSW1); VLAN23: 外部O&M traffic (SSW2),VLAN20: MXBSC与OMC-R/CBC之间的O&M控制 VLAN3,4: NE1oE telecom traffic VLAN3: MUX1<->SSW1<->TPGSM(1or 2) routing telecom traffic VLAN3: MUX2<->SSW2<->TPGSM(1or 2) routing telecom traffic Traffic flow 见下图：
