H80ASHLM Board Description

H80ASHLM Board Description

The H80ASHLM board is a 16-port SHDSL.bis service board. It works with the SHDSL transceiver unit-remote (STU-R) to provide 16-channels of SHDSL 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 3-144  Working principle of the H80ASHLM board

The basic working principle of the H80ASHLM board is as follows:

  • The control module loads the board software, controls the running of the board, and manages the entire board.
  • The forwarding module processes the signals. After being processed by the control module, the signals are transmitted to the backplane bus through the interface of the backplane.
  • The interface module inputs, outputs, and converts the signals.
  • 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 MELT module provides the MELT test function for digital subscriber lines.
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 logical 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 from the backplane bus, performs CAR on the IP packets, reorganizes the IP packets into ATM/PTM packets, and transmits the ATM/PTM packets to the interface module. The interface module converts the ATM/PTM packets into analog signals and transmits the signals to subscriber lines.
