Huawei H801ASPB H808ASPB H809ASPB 64-port VOIP Subscriber Board

The H801ASPB/H808ASPB/H809ASPB board is a 64-port VOIP subscriber board, providing 64 channels of VoIP POTS access services.

The basic working principle of the H801ASPB/H808ASPB/H809ASPB board is as follows:

1, The control module processes the high-level protocol between the H801ASPB board and the control board, manages the service ports of the H801ASPB board, controls the DSP module, and controls the GE interface module.

2. The subscriber line interface module provides 64 channels of the POTS service.

3. The processing module converts the pulse code modulation (PCM) data into IP voice packets, and supports the decoding/encoding and the echo suppression functions.

4, The GE interface module supports the GE communication between the H801ASPB board and the control board.

5, The power module supplies power to each functional module of the board.

6, The clock module provides clock signals for each functional module of the board.

Working principle of the H801ASPB/H808ASPB/H809ASPB board:

The service process is as follows:

1,In the upstream direction, the service data is transmitted to the H801ASPB board through the POTS port. After being processed by the TDM processing module and the VoIP service processing module, the service data is transmitted to the control board through the backplane and then to the upstream direction.

2,In the downstream direction, the service data is transmitted from the control board to the TDM processing module and the VoIP service processing module through the backplane bus and the interface module. After being processed by the TDM processing module and the VoIP service processing module, the service data is transmitted to the subscriber through the POTS port.
