Figure 1 Working principles of the H836VDLE board

The basic working principles of the H836VDLE board are as follows:

• The chipset module implements functions, such as amplification, filtering, A/D and D/A conversion, coding/decoding, and encapsulation/decapsulation for signals.

• The protection module protects and isolates the board from lightning strikes.

• The control module decodes signals and monitors signals.

• The splitter module separates POTS signals from combined signals (VDSL2 signals and POTS signals).

• The power module supplies power to other function modules of the board.

• The clock module provides working clock for other function modules of the board.
