H806VPGA Board Description

H806VPGA Board Description

The H806VPGA board is a vectoring centralized processing board, and it works with vectoring-supporting VDSL2 board to achieve vectoring on the MA5600T.

Functional Specifications

The H806VPGA board supports the following functions and features:

  • Automatic power shutdown in case of a high temperature
  • Working with the H802MABC and H803MABC backplane and the H806VPGA board can be installed only in slots 8 and 11. When installed in slot 8, the H806VPGA board processes the vectoring services of slots 1-6. When installed in slot 11, the H806VPGA board processes the vectoring services of slots 13-18. Slots 7 and 12 cannot house vectoring service boards but can house other service boards.
  • G.993.5

Technical Specifications

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

Working Principles

Figure 3-140  Working principles of the H806VPGA board

The basic working principles of the H806VPGA board are as follows:

  • The control and service integration module, manages the H806VPGA board and service boards, and calculates the link signal compensation for service boards.
  • The switching module is used for the interconnection between the main control board, control and sercvice integration module.
  • The power module supplies power to other function modules of the board.
  • The clock module provides the working clock for other function modules of the board.

The service process of the H806VPGA board is as follows:

  • H806VPGA connects with other service boards by vectoring bus, which enables the H806VPGA board to calculate the link signal compensation for each service board.
  • H806VPGA interconnects with the other H806VPGA by vectoring bus, which provides link signal compensation for vectoring.
