H80BVDPE Is Huawei MA5608T VDSL2 Service Board
H80BVDPE is a 64-port VDSL2 over POTS service board with built-in splitter
The H80BVDPE board works with the VDSL transceiver unit, remote terminal end (VTU-R) to provide 64 channels of VDSL2 access services.
The basic working principle of the H80BVDPE board is as follows:
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 DC block isolates the direct current. The protector protects the high voltage.
The splitter module separates POTS signals from VDSL2 signals over the subscriber line.
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.
The forwarding module processes services. For details, see the description of service processing.
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.
