H80DVCPD Board Description

H80DVCPD Board Description

H80DVCPD is a 64-port VDSL2 over POTS Service Board. Using its VDSL2 port, the H80DVCPD board works with the VDSL transceiver unit, remote terminal end (VTU-R) to provide 64 channels of VDSL2 access service. In addition, it supports vectoring.

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 3-133  Working principle of the H80DVCPD board

The basic working principle of the H80DVCPD 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 converts between the ATM/PTM service and the IP service, and also supports flow control and scheduling.
  • The interface module provides the ports for information exchange.
  • The protection module protects and isolates the board from lightning strikes.
  • 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 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 PTM packets. The forwarding module encapsulates the reassembled 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 PTM packets, and then transmits the PTM packets to the interface module. The interface module then converts the 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.
