• Automatic adaptation to GPON and GE modes: The MA5612 provides two uplink ports using the small form-factor pluggable (SFP) optical modules to meet different site requirements.
• Flexible board configurations.
• Support for multiple clock synchronization technologies, such as synchronous Ethernet, E1 line clocks and GPON line clocks.
• Operable IPTV services: Strong service switching capability, packet forwarding capability, and high integration (data exchange and user management) enable the MA5612 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 MA5612 allows remote issuing of configuration. A management channel and service channel are created after the MA5612 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 MA5612 supports the working temperature from -40℃ to 65℃, 6 kV lightning protection, and corrosion-proof design of boards.
• Prudent security measures: The MA5612 meets security requirements of telecom services to ensure system and user security.
• Environment-friendly and energy conservation: The MA5612 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.
• 12 V backup power supply: The size and price of the battery are one-fourth of those of 48 V backup power supply.

Family broadband service scenario

In the upstream direction, the MA5612 connects to the optical line terminal (OLT) through the gigabit passive optical network (GPON). In the downstream direction, the MA5612 connects to a PC by using the category-5 cable to provide high-bandwidth broadband, voice, and video services and connects to a telephone by using twisted pairs to provide plain old telephone service (POTS) services.

Enterprise leased line scenario

For a traditional private branch exchange (PBX) and router, the MA5612 provides a TDM E1 port to transmit leased line services to the OLT by using the native TDM technology. The MA5612 also provides a primary rate interface (PRI) that converts E1 frames transmitted by the PBX to Session Initiation Protocol (SIP) or H.248 packets and transmits them to the OLT. For an IP PBX and router, the MA5612 provides an FE or GE port to transmit leased line services to the OLT by using the virtual local area network (VLAN) transparent transmission technology.
