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.

processing functions of the BSC6000. One service rack can be configured with three

subracks.

According to the requirement of service quantity,

each BSC6000 system contains a maximum of

three service racks.

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

respectively. The slots are numbered

00–27 from the front to the rear.

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.

Bit Meaning

6 Odd parity check bit

7 Reserved, generally set to 0

8

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

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


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.


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.
