Module
The basic working principle of the H802P2CA board is as follows:
l The control module controls the board software loading and board running, and manages
the board.
l The electronic switch module implements switching of service signals during the active/
standby switchover.
l The PON interface module provides SFP GPON port.
l The service process module implements GPON upstream transmission and provides time
synchronization, and supports line clock as the system clock.
l The power module supplies power to each functional module of the board.
l The clock module provides the working clock for each functional module of the board.
