H801TOPA Is Huawei MA5600 Series TDM Service Board
Huawei MA5600 Board H801TOPA Overview
The H801TOPA is a TDM traffic over PSN board. It uses the daughter board to transmit services upstream.
The H801TOPA board supports the following functions:
Native TDM function (when the NH1A/O2CE daughter board is configured)
CESoP function (when the EH1A/CSSA daughter board is configured)
TDM signal upstream transmission through the 16 channels of E1 port (when the NH1A/EH1A daughter board is configured)
TDM signal upstream transmission through the 2 channels of STM-1 optical port (when the O2CE/CSSA daughter board is configured, )
The basic working principle of the H801TOPA board is as follows:
The control module loads the board software, controls, and manages the entire board.
The service processing module allocates the GE bus of the backplane and processes signals.
The interface module converts signals.
The power module supplies power to each functional module of the board.
The clock module provides clock signals for each functional module of the board.
To provide the related functions, the H801TOPA board must be configured with a matching daughter board.
