• Automatic adaptation to GPON and GE modes: Each of them provides two uplink ports using the small form-factor pluggable (SFP) optical modules to meet different site requirements.
• Rich specifications: They fully meet requirements for pure LAN access service or voice service on an FTTB network, inherits traditional voice services, and supports migration of narrowband users.
• Plug-and-play (PnP) service provisioning: They allow remote issuing of configuration. A management channel and service channel are created after each of them is powered on and registerssuccessfully. Manual onsite configuration is not required.
• Strong QoS capability: Support bandwidth management based DBA, flexible service mapping and accurate service management base the flow. The strong quality of service (QoS) capability provides the user difference service experience.
• High performance IPTV services management: Strong service switching capability, packet forwarding capability, and high integration (data exchange and user management) enable them to have carrier-class multicast operation capability.
• Perfect voice features, supporting basic services (voice service, fax service, and modem service) and supplementary services (threeway calling, call waiting, call transfer, calling line identification presentation, and calling number restriction).
• Efficient management and maintenance: free of field software commissioning, remote acceptance, remote upgrade and patch installation, and remote fault location.
• Environment-friendly and energy conservation: Each of them uses a highly effective power supply system to reduce system power consumption. Each of them uses passive cooling without any fans to reduce device power consumption. Each of them uses POTS short-loop design to reduce port power consumption in short distances.

The MA5620 and MA5626 are used on an FTTB network and are installed in a network cabinet in a corridor. They connect to the optical line terminal (OLT) through GPON uplink ports and connect to PCs by using category-5 cables to provide high-bandwidth broadband, voice, and video services and connect to telephones by using twisted pairs to provide plain old telephone service (POTS) services.
