The basic working principle of the H801SPUC board is as follows:
l The control module loads the board software, controls the running of the board, and
manages the entire board.
l The interface module receives signals and then transmits the signals.
l The service processing module processes Ethernet packets, processes and forwards
service data packets, and implements service flow management.
l The power module draws -48 V power from the backplane and converts the power into
working power for each functional module of the board.
l The clock module provides clock signals for each functional module of the board.
