Overview

MA5616 series DSLAM have 32/64/96/128/256 ports subscriber line interface with POTS splitter built-in achieved 2U height space saving design. MA5616 came with unique bandwidth management, flow prioritization and data flow security control key feature. MA5616 provided QoS (Quality of Service) capability to meet triple play (voice, data, video)
 requirement, support ADSL /ADSL2/ADSL2+/VDSL2/ G.SHDSL/VOIP interface, No matters in features, performance, and cost wise, MA5616 is the best choice for NSP (network service provider) .

• Product Description Positioning and Features

             ~Provides lightning protection and anti-interference functions.
              ~Starts up at -25°C.
              ~Endures high temperatures and it can work normally for a long time at 65°C (the maximum working temperature).
              ~ Supports the temperature detection function, When the temperature exceeds the threshold, the system generates an alarm.

             ~Supports protection of the subscriber port:
 ?                      DSL port: enhanced K20, common mode 4 kV
 ?                      POTS port: common mode and differential mode, 4 kV
               ~Supports the power protection (2 kV in differential mode and 4 kV in common mode).
               ~In the AC + backup power configuration, the battery can be used as the backup power. When the AC power supply fails, the battery supplies power to the system.

                 Inthis case, the broadband services are shut off, and the narrowband services are normal.
               ~Supports the intelligent speed adjustment of the fan. The system can automatically adjust the fan rotating speed according to the working temperature,which  brings positive effect to the reliable energy saving and noise reduction.
               ~Supports replacing the fan tray independently.
               ~Adopts the derating design for the electronic components to improve the reliability.

              ~Provides the corrosion-proof design and reduces the cable routing on the board surface. The heat dissipation layout is reasonable (to prevent the condensation from forming because of the temperature difference).
                ~Supports the MGCP/H248/SIP dual homing. When the MGCP/H.248/SIP protocol is used, the MDU can be configured with up to two MGCs. When the MGC is switched  over or the MDU detects the fault of the primary uplink,the system automatically switches to the other MGC.
                ~Supports emergency standalone. When the MDU upstream port is interrupted,  the system automatically starts the emergency standalone function. Then,the subscribers of the same MDU can call and communicate with each other.
                 ~Supports virtual noise. The system uses the virtual noise mechanism to decrease the line rate (the system adjusts the line rate according to the SNR), which improves  the anti- interference capability of the system.  
•High and Guaranteed QoS
 The MA5616 has a high and guaranteed QoS, which lays the foundation for service
 management.
 ~Traffic-stream-based priority marking
 ~ACL-based priority marking
 ~Three scheduling modes, namely priority queuing (PQ), weighted round robin (WRR), and PQ+WRR

           ~DBA-based bandwidth management of the GPON port
            ~Mapping upstream/downstream services to different priority queues for scheduling based on the priority
            ~ACL-based access control
            ~Two rate three color marker (trTCM)-based IP traffic profile, and rate limitation on a subscriber port
            ~TCONT-based priority service in the upstream GPON transmission direction of the MDU.
•System Security
 ~ Filters the packets by specified IP address, port, and protocol type.
 ~ Filters the packets by the source MAC address and destination MAC address of the  packets.
 ~  Filters the packets by the source route options.
 ~  Supports ACL-based (allow/deny) access control.
 ~  Supports static binding of the MAC addresses.
 ~  Supports suppression of broadcast, multicast, and unknown unicast packets of the GPON port Ethernet port.
 ~  Supports SNMPv3 on the basis of SNMPv1 and SNMPv2c. Provides three key services, namely, authentication, encryption, and access control, considering the security defect in SNMPv1 and SNMPv2c.(Note: The device on the CO side must also support SNMPV3.)
 ~  Supports changing the password for the Root user.
 ~  Supports GEM port-based encryption through the PLOAM messages in the downstream direction, by using the Advanced EncryptionStandard (AES) 128 encryption algorithm.
 ~  Supports dynamic key switching based on ITU-T G.984 through the PLOAM messages.
 ~  Supports dual GE port (backup for each other) upstream transmission.
 ~  Supports the virtual MAC (VMAC).
 ~  Supports anti-ICMP/IP attacks.    

           ~ Supports setting the anti-DOS attack function through the CLI and NMS.            
•Subscriber Security
 ~  Supports L2 isolation and controlled mutual access of the subscribers.
 ~  Supports the global Policy Information Transfer Protocol (PITP) and the PITP controlled by VLANs.
 ~  Supports global DHCP Option82 and the DHCP Option82 controlled by VLANs.
 ~  Supports DHCP Option82 so that the information about the physical location of a subscriber is contained in the authenticationpacket, thus enhancing the DHCP security.
 ~  Supports global-level dynamic anti-MAC address spoofing. After the subscriber passes the authentication, the MAC address of the subscriber is bound with the service stream dynamically.
 ~  Supports the global and VLAN-level anti-MAC address spoofing and anti-IP address spoofing based on the DHCP protocol.
 ~  Supports the anti-MAC address spoofing function for the subscriber who uses the PPPoE protocol.
 ~  Supports the management of the operation rights of the maintenance and management personnel according to different right levels.
•Multicast Protocol
 ~  Internet Group Management Protocol (IGMP) V2 and IGMP V3
 ~  IGMP proxy and IGMP snooping
• Multicast Service
 ~  Up to 32 multicast VLANs and 1024 programs for each multicast VLAN
 ~  1024 multicast groups
 ~  Up to 16 multicast groups that the subscribers under each service port can join concurrently
 ~  Delay shorter than 50 ms for joining or leaving the multicast group
 ~  Flexible and easy channel control
 ~  IGMP packet statistics
 ~  High performance processing of IGMP packets, which enables the broadband TV (BTV) service
 ~  Multicast VLAN, program, and subscriber management
 ~  Setting and querying the quick-leave function through the NMS or the CLI
 ~  Global-level switching of IGMP modes
 ~  Filtering downstream multicast packets (The downstream multicast traffic that is not contained in the multicast filtering table is discarded.)                                           

~ Statically joining a multicast program Adding, modifying, and deleting programs in batches

• Perfect Voice Features
