signal signal
The control module loads the board software, controls the running of the board, and
manages the board.
The protection module protects and isolates the board from lightning strikes.
The splitter module separates POTS signals from ADSL2+ signals over the subscriber
line.
The broadband interface module converts the ADSL2+ line signals into cell flows.
The broadband service processing module implements functions such as encoding/
decoding, analog-to-digital conversion, and line drive for ADSL2+ services. It then
sends ADSL2+ services to the forwarding module through the UTOPIA interface.
