H80BVDQM Board Description

H80BVDQM Board Description

H80BVDQM is a 64-port VDSL2 over ISDN service board. Using its VDSL2 port, the H80BVDQM board works with the VDSL transceiver unit, remote terminal end (VTU-R) to provide 64 channels of VDSL2 access service.

Feature and Specifications

Please refer to "64-Channel VDSL2 Service Board Comparison".

Technical Specifications

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

Working Principle

Figure 3-137  Working principle of the H80BVDQM board

The basic working principle of the H80BVDQM 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 interface module provides two functions:
    • In the upstream direction, the interface module converts line signals into cell flows, aggregates the cell flows to the forwarding module, and then reassembles the cell flows into ATM/PTM packets.
    • In the downstream direction, the interface module converts the ATM/PTM cell flows sent from the forwarding module into line signals that are transmitted downstream.
  • The forwarding module processes services. For details, see the description of service processing.
  • The MELT module provides the MELT test function for digital subscriber lines.
  • 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 processing is as follows:
  • In the upstream direction, the interface module converts the VDSL2 line signals into cell flows, aggregates the cell flows to the forwarding module, and then reassembles the cell flows into ATM/PTM packets. The forwarding module encapsulates the reassembled ATM/PTM packets into IP packets, performs CAR on the IP packets, and then sends the IP packets to the backplane bus through the backplane port and then to the control board. After being processed by the control board, the IP packets are transmitted upstream to the upper-level device through the optical or electrical port.
  • In the downstream direction, the forwarding module decapsulates the IP packets sent from the backplane bus, performs CAR on the packets, reassembles the packets into ATM/PTM packets, and then 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.

Front Panel Port



  • When cables from the xDSL ports are routed to an outdoor environment or the user side, the MDF must be installed with a protective unit.
