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.

8

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

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.
