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. number. –5 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. 0.

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 Tandem Free O Operation peration (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.

Clock Subsystem GGCU Reference Clock Input To input the active-standby clock of the GGCU, you can use the t he 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

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.
