H802DSRD Board Description

H802DSRD Board Description

The H802DSRD board is a 32-port ISDN digital subscriber board, providing 32 channels of ISDN access 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 3-95 illustrates the working principle of the H802DSRD board.

Figure 3-95  Working principle of the H802DSRD board

The basic working principle of the H802DSRD board is as follows:
  • The CPU module controls calls, processes call protocols, and packages voice data.
  • The ISDN service processing module processes the ISDN service of the board, including extracting signaling and switching data.
  • The interface module converts between the media independent interface (MII) interface and the GE interface.
  • 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 board through the ISDN service processing module and is packaged by the CPU module. The interface module converts the packaged data into GE packets and transmits the packets to the control board through the GE bus of the board. Then, the packets are transmitted upstream.
  • In the downstream direction, GE packets are transmitted from the control board to the interface module of the H802DSRD board through the backplane bus. The GE packets are decapsulated by the CPU module, processed by the ISDN service processing module, and then converted into service data. The service data is transmitted to the subscriber through the interface module.
