High Integration: A single cabinet can support 2048 TRXs
2048TRXs can be supported by one single BSC6000V900R008 cabinet and built-in PCU can be integrated , which can save much space of central equipment room.
Power consumption will decrease a lot because of high integration. Typical power consumption of TC/BM combined full configuration is 3340W when E1 transmission is used on A/Abis interface, and 2325W, when STM1 is used on A Interface and E1 is used on Abis Interface.

Dip switch of Subracks The DIP switches on the BSC subrack are
used to define the numbering of the BSC subrack.
The DIP bits are numbered in ascending order from bit 1 to bit 8. ON represents digit 0 and OFF represents digit 1.
As the DIP switches use odd parity check, the number of 1s in the eight DIP bits must be an odd number.
Set the DIP switch as follows: Set bits 1–5 and 8 first. Set bit 7 to 0. Check the number of 1s in the bits of the DIP switch. If the number of 1s is even, set bit 6 to 1. If the number of 1s is odd, set bit 6 to 0.

The automatic DIP bit of the GSCU board in the central subrack. 0, the starting of boards is highly dependent on the GBAM server, namely that the boards load from the server after starting. 1, the starting of boards is less dependent on the GBAM server, namely that the boards check the validity of the Flash file when starting, and load from the Flash file if the Flash file is valid or load from the server if the Flash file is invalid.

Board——GDPUX/ GDPUC GDPUX / GDPUC process CS services and are configured in
00~03 or 08~13, boards perform the voice coding and
decoding function. It works as subrack resource pool mode. GDPUX / GDPUC perform function as follows:
Provides Tandem Free Operation (TFO) functions, When the calling
and called MSs use one voice coding scheme, the voice signals are
encoded only once at the originating MS and decoded only once at the
terminating MS. This reduces repeated encoding and decoding and
improves the quality of speech services.
Provides voice enhancement function
Detects voice faults automatically
GDPUX is configured in BM: Provides format conversion for 3740 IP speech paths and HDLC

The GGCU is the general clock unit in the BSC6000. The active
GGCU and the standby GGCU are configured in slots 12 and 13 in
the GMPS. The GGCU board provides synchronous timing signals
for the system The GGCU has the following functions:
Generating and keeping synchronous clock signals Keeping the consistency of synchronization information output from the active and
standby GGCUs
HUAWEI TECHNOLOGIES Co., Ltd. HUAWEI Confidential Page 48
Clock Subsystem GGCU Reference Clock Input
To input the active-standby clock of the GGCU, you can use the signals provided by the BITS and the 2.048MHz clock signal extracted from the upper-level clock by the interface panel in the service subrack.
The GGCU backplane uses the interface panel of the same subrack to extract the 8 KHz clock signals from the
upper-level clocks. Reference Clock for the GMPS or GEPS
The reference clocks are provided by the GGCU. The reference clocks generate 8kHz clock signals through the GGCU.
GMPS: The clock signals are sent to the GSCU in the GMPS subrack through the backplane. Then, the clock signals are sent to other boards in the same subrack.
GEPS: The clock signals are sent to the GSCU board in the GEPS subrack through the clock cable. Then, the
signals are sent to other boards through the backplane. Reference Clock for the GTCS
Each GTCS extracts line clock from the A interface. The line clock is processed through A interface panel and then generates 8 KHz clock signals.
The clock signals are sent to the GSCU in the subrack through the backplane. Then the clock signals are sent to other boards in the same subrack.
HUAWEI TECHNOLOGIES Co., Ltd. HUAWEI Confidential Page 49
The connection of the GGCU of the main subrack and the GSCU of the
extension subrack is shown as following figure: The active GGCU and the standby GGCU output 10-way signal channel
respectively. A signal channel of an active GGCU and that of a standby GGCU are
integrated through the Y-shaped cable.
GGCU support six service subracks, one is the GMPS, others five are the GEPSs
where the 10 cables from GSCUs to GGCU can be connected at most. Any of component including GGCU, Y-shaped cable, and GSCU is faulty, the
system clock still can work normally.

Hardware configuration Principle Service processing boards
Single GDPUX supplies 960 voice circuits coding/decoding, it works as resource pool in subrack.
If just need 1 board, we can configed as 2 boards, Otherwise do not config as N+!. DPUX supports 3740 voice circuits frame conversion or transmission between TRAU/IP/HDLC
and TRAU, We can config as N+! Mode. Single GDPUP supplies 1024 MCS-9 PDCH channel of processing packet service, supports
1024 cells at most, GDPUP is resource pool of whole system and could be inserted in rear slots; Number of GDPUP+GDPUX+GDPUC couldn’t be more than 10;
GXPUM/GXPUT GXPUM must be inserted in 0&1 slots of GMPS/GEPS fixedly; GXPUT is inserted in 2&3 slots of GMPS/GEPS by requirement, when the TRX of current
subrack is less than 256, CXPUT may not be configured, if needs, it’s certainly; Interface Specification
Abis: GEIUB/GOIUB support 256TRX(HR)at most, GEHUB GFGUB/GOGUB also support
384TRX(HR)at most; A: GOIUA/GEIUA are configured 5 groups per subrack at most, if A interface uses optical
transport, single subrack could access 9600 CIC at most;
