H832PDVAA Board
H832PDVAA is a DC power board. It supplies one channel of -48 V DC power to the backplane, or converts -48 V DC power to +3.3 V DC and +12 V DC and then supplies power to service boards, control board, and fan monitoring board using the backplane.

Working Principles
Figure 1shows working principles of the H832PDVAA board.
Figure 1Working principles of the H832PDVAA board
Basic working principles of the H832PDVAA board are as follows:
The protection and filter circuit protects the -48 V DC power input against surges and lightning strikes for current limiting and also filters EMI for the -48 V DC power input.
The soft-start circuit provides the soft-start function for the -48 V DC power input of the +12 V DC and +3.3 V DC power modules.
The output filter circuit filters the output of the +12 V DC and +3.3 V DC power modules.
The detection and alarm circuit detects the availability of the -48 V DC power and reports related alarms.
The electronic label and board type reporting circuit stores the board manufacturing information and reports the board type.
The H836VPBA daughter board implements the vectoring function for calculating and canceling the crosstalk on narrowband lines.
Front Panel Port
The MA5616 is an industry-leading remote PON multi-dwelling unit (MDU) with a plug-in design. It has the following features: high access density, superior processing performance, high reliability, easy maintenance, energy saving, and future-oriented architecture design. The device provides ADSL2+, VDSL2, SHDSL, POTS, FE, P2P, ISDN, and Combo user ports, and supports dual upstream transmission channels through auto-negotiation GPON/EPON/GE ports at the network side. It can be smoothly upgraded to support 10G PON. The MA5616 can be used as a mini-DSLAM/mini-MSAN in FTTC/FTTB scenarios. It can be deployed indoors, for example, on a corridor wall or outdoors, for example, in an outdoor cabinet to provide high-bandwidth, flexible density, and multi-scenario service coverage for multi-resident buildings and small and medium-sized enterprises (SMEs).
