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.
The narrowband interface module provides access to 48-channel narrowband service.
The narrowband service processing module encodes and decodes narrowband voice
services and converts analog signals into digital signals. It then sends narrowband voice
services to the forwarding module through the S3MII interface.
The forwarding module converts broadband signals and narrowband signals into GE
signals for upstream transmission through the backplane.
The power module supplies power to other functional modules of the board.
The clock module provides the working clock for other functional modules of the board.
