H803SHDA Board Description

H803SHDA Board Description

H803SHDA is a 16-port SHDSL service board. It board works with the SHDSL transceiver unit-remote end (STU-R) to provide 16 channels of SHDSL access services.

Functional Specifications

Please refer to "SHDSL Service Board Comparison".

Technical Specifications

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

Working Principle

Figure 3-141  Working principle of the H803SHDA board

The basic working principle of the H803SHDA board is as follows:

  • The control module loads the board software, controls the running of the board, and manages the board.
  • The protection module protects and isolates the board from lightning strikes. The DC block isolates the direct current. The protector protects the high voltage.
  • The forwarding module forwards signals. After being processed by the control module, the signals are then sent to the backplane bus through the backplane connector.
  • The interface module inputs, outputs, and converts signals.
  • The power module supplies power to other functional modules of the board.
  • The clock module provides the working clock for other functional modules of the board.
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 logic 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 that are transmitted from the backplane bus, performs CAR on the packets, reassembles the packets into ATM/PTM packets, and transmits the ATM/PTM packets to the interface module. The interface module then converts the ATM/PTM packets into analog signals, and transmits the analog signals over the subscriber line.
