The SmartAX MA5616 (the MA5616 for short) is an industry-leading remote multi dwelling unit (MDU) launched by Huawei, which supports flexible configurations and provides broadband services on Fiber To The Building (FTTB) and Fiber To The Curb (FTTC) networks. The MA5616 is a box-type device measuring 2-U high and 19-inch wide and providing two GPON or GE uplink ports and ADSL2+, VDSL2, SHDSL, POTS, ISDN, FE and GE ports. The MA5616 features a high access density, high processing capability, high reliability, easy maintenance, environment-friendlily and energy conservation, and future-oriented architecture design and can be used in corridors, cabinets, indoor, and outdoor usage scenarios.

• High access density: The MA5616 supports a maximum of 256 POTS users, 128 ADSL2+ users, 192 VDSL2 users, or 64FE users. The MA5616 supports 128 POTS users and 128 ADSL2+ users simultaneously by using a combo board.
• Flexible configurations: Service boards are slot compatible and different types of ports can be configured flexibly, improving the actual configuration ratio and meeting different customer requirements.
• Support for the combo board to improve the access density, reduce the space of the equipment room, and simplify cable routing complexity.
• Support for the P2P optical access board (4GE+4FE) to provide high bandwidth for valued customers.
• Support for 48-V backup power (lead-acid batteries and LiFePO4 batteries).
• Operable IPTV services: Strong service switching capability, packet forwarding capability, and high integration (data exchange and user management) enable the MA5616 to have carrier-class multicast operation capability.
• Perfect voice features, supporting basic services (voice service, fax service, and modem service) and supplementary services (three-way calling, call waiting, call transfer, calling line identification presentation, and calling number restriction).
• Plug-and-play (PnP) service provisioning: The MA5616 allows remote issuing of configuration. A management channel and service channel are created after the MA5616 is powered on and registers successfully. Manual onsite configuration is not required.
• Efficient management and maintenance: free of field software commissioning, remote acceptance, remote upgrade and patch installation, and remote fault location.
• High reliability: The MA5616 supports the working temperature from -40℃ to 65℃, 6 kV lightning protection, and corrosion-proof design of boards.
• Prudent security measures: The MA5616 meets security requirements of telecom services to ensure system and user security.
• Environment-friendly and energy conservation: The MA5616 uses a highly effective power supply system to reduce system power consumption. It uses an intelligent fan system that adjusts the rotating speed to reduce power consumption when the system is idle. It uses high-performance chipset to reduce chipset power consumption. It uses POTS short-loop design to reduce port power consumption in short distances.
• Future-oriented architecture design: The MA5616 provides corresponding service boards to quickly meet operators' network and service requirements in the future without any modification.

The MA5616 provides two GPON or GE uplink ports and provides multiple services by supporting flexible board configurations. The MA5616 provides broadband, voice, and video services through ADSL2+/ VDSL2/FE boards, voices service through POTS boards, leased line services through SHDSL or P2P boards.
