Working Principle
Figure 1 Working principle of the H80ASHLM board

The basic working principle of the H80ASHLM board is as follows:
The control module loads the board software, controls the running of the board, and manages the entire board.
The forwarding module processes the signals. After being processed by the control module, the signals are transmitted to the backplane bus through the interface of the backplane.
The interface module inputs, outputs, and converts the 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.
The MELT module provides the MELT test function for digital subscriber lines.
The service process is as follows:
In the upstream direction, the interface module transmits subscriber line signals to the forwarding module. The forwarding module reorganizes the cell flow into ATM/PTM packets, encapsulates the ATM/PTM packets into IP packets, and performs CAR on the IP packets. Controlled by the logical switch, the IP packets are transmitted to the backplane bus through the backplane interface.
In the downstream direction, the forwarding module decapsulates the IP packets from the backplane bus, performs CAR on the IP packets, reorganizes the IP packets into ATM/PTM packets, and transmits the ATM/PTM packets to the interface module. The interface module converts the ATM/PTM packets into analog signals and transmits the signals to subscriber lines.
