The basic working principle of the H807ADPE board is as follows:
l The control module loads the board software, controls the running of the board, and
manages the entire 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 ADSL2+ signals over the subscriber
line.
l The interface module supports two functions:
– In the upstream direction, the interface module converts line signals into a cell flow,
aggregates the flow to the forwarding module, and then reorganizes the flow into
ATM packets.
