H801ASRB Board Description

H801ASRB Board Description

The H801ASRB board is a 32-port analog subscriber board, providing 32 channels of VoIP POTS services.

Feature and Specifications

Please refer to "Voice Board Comparison".

Technical Specifications

Please refer to "Power Consumption and Maximum Frame Size of Boards".

Working Principle

Figure 3-87 illustrates the working principle of the H801ASRB board.

Figure 3-87  Working principle of the H801ASRB board

The basic working principle of the H801ASRB board is as follows:
  • 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.
The service process is as follows:
  • 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 transmitted to the backplane bus through the interface module, and then transmitted upstream through the optical or electrical port of the control board.
  • In the downstream direction, the service data is transmitted to the control board through the optical or electrical port. The service data is transmitted to the processing module through the backplane bus and the interface module. After being processed by the processing module, the service data is transmitted to the subscriber through the POTS port.
