Huawei DSLAM MA5616 Power Distribution Principle and Working Principles

Power Distribution Principle

Huawei MA5616 can be powered by a DC or AC power source through a DC or AC power board. The power board outputs -48 V DC, +3.3 V DC, and +12 V DC power to the backplane. Then the backplane provides the -48 V DC and +3.3 V DC power for the service board and control board, and provides the +12 V DC power for the fan monitoring board.

Working Principles

Huawei MA5616 supports GPON, 10G GPON or GE upstream CCUE transmission by using its control board and provides broadband and narrowband access services by using different service boards.

Working principles of the MA5616 chassis 

The working principles of Huawei DSLAM MA5616 chassis are as follows:

• The control board transmits services upstream and subtends device through subboards and manages service boards.
• The power board outputs DC power to the backplane and then the backplane transmits the power to the fan tray, service boards, and control board.
• The broadband or narrowband service board is connected to a user-side device by using a subscriber cable, and then the control board puts the user-side device through to the IP network. In this way, broadband or narrowband access service is provisioned to the user-side device.
• The fan monitoring board monitors the fan tray and transmits the monitoring signal to the control board through the backplane.

Do you know Huawei small-size DSLAM MA5616 and the Highlights? (1)

Huawei DSLAM SmartAX MA5616 Multi-service Access Module (MA5616 for short) is a 2-U high and 19-inch wide board-inserted device. It provides four service slots for flexible board configurations.

The MA5616 applies in fiber to the building (FTTB) and fiber to the curb (FTTC) scenarios. It can also function as a mini-digital subscriber line access multiplexer (DSLAM) or multiservice access node (MSAN). The MA5616 can be installed in corridors or cabinets (indoor or outdoor).

Each MA5616 provides user-to-network interfaces (UNIs), such as ADSL2+, VDSL2, SHDSL, POTS, FE, P2P, ISDN, or combo ports, and two network-to-network interfaces (NNIs) that support autonegotiation among GPON, EPON

Hardware Structure

Commissioning serial port/Environment monitoring port

For the CON port: supports local and remote maintenance, which allows users to configure the MA5616 using software, such as HyperTerminal, through CLI. The default baud rate is 9600 bit/s.

For the ESC port: connects to an environment monitoring unit (EMU), which sends monitored environment monitoring parameters to the MA5616.

Uplink optical port

Supports auto-negotiation among GPON, EPON, and GE. Provides GPON, EPON, and GE upstream transmission or GE cascading. When this uplink optical port is used as a GE port, it is an alternative to the GE electrical (RJ45) port.

Maintenance network port

A 100M Base-T commissioning network port, which is a front-access-cabled FE port and supports 100 Mbit/s full-duplex in auto-negotiation mode.

Clock port

Outputs 2 MHz clock pulse signals.

Environment parameter monitoring port

Can be connected to a sensor to monitor environment parameters.

GE electrical port

Supports 1000 Mbit/s full-duplex upstream transmission or cascading in auto-negotiation mode. It is an alternative to the uplink optical (SFP) port.
