The control module loads the board software, controls the running of the software, and
manages the entire board.
The BITS clock processing module selects the mode and separates the two channels of
input BITS clock signals, restores the clock for 2 Mbit/s signals, shapes the 2 MHz
signals, and outputs one channel of 2 Mbit/s or 2 MHz clock signals.
The stratum-3 clock daughter board module provides the stratum-3 system clock with the
accuracy of ±4.6 ppm.
The clock module provides clock signals for each functional module of the board.
The power module supplies power to each functional module of the board.
