illustrates the working principle of the H801ASRB board.
The control module processes the high-level protocol between the H801ASRB board and
the control board, manages the service ports of the H801ASRB board, controls the DSP
module, and controls the GE interface module.
The subscriber line interface module provides 32 channels of the POTS service.
The processing module converts the pulse code modulation (PCM) data into IP voice
packets, and supports the decoding/encoding and the echo suppression functions.
The GE interface module supports the GE communication between the H801ASRB
board and the control board.
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.
In the upstream direction, service data is transmitted to the H801ASRB board through
the POTS port. After being processed by the processing module, the service data is
