MSOFTX3000 Frame
The MSC SERVER UNIT frame is designed in conformity with the IEC297
standard and has the following features.
The frame is 19 inches wide and 8U high.
The front boards and back boards are plugged into the backplane of the
frame. All cables are led out of the frame from the back.
The frame accommodates 21 slots. The power boards (UPWR) occupy
four slots.
The frame enables temperature
detection and fan speed adjustment functions.

WCDB
It provides UMG resource management, outgoing trunk selection, and WVD
B distribution agent management (MSRN number allocation, WVDB mainten
ance command forwarding) functions.
The WCDB contains global data which can be accessed by all WCCUs/WCS
Us and WVDBs.
Because the WCDB is an accessed center, its load is relatively large. In
small-capacity configuration mode, its functions can be implemented by
one pair of WCDBs.
In a large-capacity configuration mode, different functions must be distrib
uted to different WCDBs.
HUAWEI TECHNOLOGIES CO., LTD. Page 40All rights reserved
WVDB The VLR Database Board (WVDB) is a front board used to store the subscrip
tion data of mobile subscribers.
In a large-capacity application, multiple pairs of WVDBs are required to store
the subscription data.
The subscription information of one subscriber is stored in the same pair
of WVDBs.
The principles for distributing subscriber data on different WVDBs have b
een described in the Section about WCDB (also named WVDB distributio
n agent function).
Such distribution is transparent for the WCCU/WCSU service layer.

WALU
The Alarm Unit (WALU) is a front board installed fixedly in slot 16 in
each frame. Its functions are as follows:
Acting as a slave node, communicating with the master node
(WSMU) through serial port bus, and controlling indicator under the
instructions of the WSMU.
Monitoring the temperature of the chassis and reporting it to the
WSMU through serial port bus.
Collecting and logically integrating fault detection signals and in-
position signals of the four power modules, reporting them to the
WSMU through serial port bus, independently implementing the
display of the working status and in-position status of the power
boards by the indicators.

Rules of Boards Configuration
WSMU, WSIU, WHSC, WALU, UPWR are mandatory and are configur
ed in fixed slots.
0 ~ 5,10 ~ 15 slots are used to install service boards (front boards) a
nd interface boards (back boards). (0,1), (2,3), (4,5), (10,11), (12,13),
(14,15) are slots pair. It is recommended that active and standby board
s are installed in one pair of slots.
When TDM is used, WCKIs (back boards) are configured fixedly in slot
s 13 and 15 of the basic frame, and each board occupies two slots. It i
s recommended to insert the WEPIs (back boards) in slots 0 and 1 bef
ore other slots.
One pair of WMGCs can support the maximum capacity of the system.
They are installed in basic frame.
One pair of WCDBs can support up to 1,000,000 subscribers. The syst
em supports two pairs of WCDBs at maximum. They are installed in ba
sic frame.
