Working Principle
Figure 3-42 Working principle of the H801CITD board
The H801CITD board consists of the control module, interface module, power module, and
clock module. The basic working principle of the H801CITD board is as follows:
l The control module controls each functional module of the board and reads the vendor
information about the power board, service board, and BITS daughter board.
l The interface module provides the BITS clock port, time port, GE transparent
transmission port, and alarm port.
l The BITS clock daughter board recovers the 2 Mbit/s clock signals or shapes the 2 MHz
clock signals, which can function as the system clock source.
l The power module supplies power to each functional module of the board and +5 V DC
power to the backplane and the power board.
l The clock module provides clock signals for each functional module of the board.
