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
odd parity check is used for DIP. In the eight DIP bits,
the quantity of “1” must be odd.
Use
the following method to set: First set the DIP bit 1–5
and 8. DIP bit 7 is generally “0”. Then count the quantity of
“1” in the current DIP bits. If the quantity is even, set DIP bit
6 as “1”. If the quantity is odd, set DIP bit 6 as “0”.

Board——GDPUX

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:
DPUa
RUN
ALM
ACT

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

 GDPUP is configured when PCU is inner.
 GDPUP perform the following function：

Processes the packet services on up to 1,024 simultaneously
active PDCHs where signals are coded in MCS9.

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.

Clock Synchronization Interconnection
 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.
