The basic working principle of the H806VCPE board is as follows:
l The control module loads the board software, controls the running of the board, and
manages the board.
l The protection module protects and isolates the board from lightning strikes. The DC
block isolates the direct current. The protector protects the high voltage.
l The splitter module separates POTS signals from VDSL2 signals over the subscriber
line.
l 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.
