When BSC and MSC are located in the same equipment room, combined BM/TC is recommended, i.e., GTCS is not needed, so the configuration is more flexible.
When BSC and MSC are in different equipment rooms, separated BM/TC with remote TC will be used.

Subrack: The subrack complies with
the IEC60297 standard. The width of it
is 19 inches. A backplane is in the
middle of the subrack, and boards are
inserted from the front and the rear of
the subrack. Both the front subrack
and the rear subrack provide 14 slots.
The slots are numbered 00–27 from
the front to the rear. The BSC6000 contains three

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.

4 Subrack number control bit
5 Subrack number control bit

The automatic DIP bit of the GSCU board in the central subrack is: 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.

The GDPUX processes CS services and packet services.
GDPUX is configured in 08~11 of GMPS/GEPS or 13~27 of
GEPS, The board performs the voice and data service
processing functions. It works in subrack resource pool
mode.
The GDPUC performs the following functions:
Encodes and decodes voice signals
Provides data service rate adaptation
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

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. Page 47HUAWEI Confidential
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.
HUAWEI TECHNOLOGIES Co., Ltd. Page 48HUAWEI Confidential
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.

The BSC internal signaling flow from the Pb interface is as follows: The signaling is transmitted to the GXPUT/GXPUM in the GMPS/GEPS over the
Pb interface.
The GXPUT processes the signaling according to the LAPD protocol.
Upon reception of the signaling from the GSCU, the GXPUM processes the
signaling according to the PbIP and RR protocols.
