  • The ONU can be upgraded using the OLT.
  • The MA5616 supports batch upgrading. When MA5616s are upgraded using the OLT, the upgrade efficiency is 6000MA5616s per five hours. When MA5616s are upgraded through the NMS, the upgrade efficiency is 800 MA5616s per five hours.
  • If the upgrading fails, automatic rollback is supported to restore the original version and data, thus ensuring the system security.

Zero Touch Routine Maintenance

  • Accurate fault location
    • POTS call emulation, PPPoE dialup emulation, and multicast service emulation
    • Circuit line test and loop line test on the POTS port, DELT, SELT, and MELT on the VDSL port
    • Channel loopback detection, chipset loopback detection, and ring network detection
    • Ethernet connectivity fault management (CFM) operation, administration and maintenance (OAM) (IEEE Std 802.1ag), implementing the Ethernet monitoring and fault diagnosing
  • Remote troubleshooting
    • Remote maintenance, thus reducing the operational expenditure (OPEX)
    • Remote patch installation in batches
    • Over-temperature protection (automatic recovery)
    • Self-healing function (automatic reset upon the exhaustion of ONU dynamic resources)
    • Remote reset of the system and remote reset of the service board upon power-off
  • Comprehensive information collection
    • Packet statistics (multicast packets and PPPoE packets)
    • Backing up and uploading configuration data
    • Obtaining the accurate record of operation logs
    • Temperature detection
    • Fan monitoring unit, H831PMU, H831VESC, ESCM(MiniESC), EPS30-4815AF(Power4830), implementing environment monitoring and management
    • Boolean value monitoring (The Boolean values such as temperature, door status, and lightning can be monitored.)
  • Self-check and diagnosis of the device
    • LOS alarm and dying gasp alarm, identifying the disconnection of the ONU caused by broken optical fiber or power-off (Dying gasp: The system detects the output of the ONU power module. If the voltage drop is lower than the threshold, the system generates an alarm.)
    • Working with the N2510 (line assurance system launched by Huawei) to support intelligent diagnosis (The N2510 performs the intelligent diagnosis and sends the diagnosis result to the ONU, implementing automatic line optimization for the ONU.)

Network Performance Monitoring

  • Network optimization: The system monitors the traffic on the network side periodically. If traffic bottleneck occurs, the system adjusts the network resources and optimizes the network structure.
  • User monitoring: The system performs selective monitoring on the traffic of the user port to find abnormal traffic and invalid users.

4.High QoS

The MA5616 provides high quality of service (QoS) solutions to facilitate the management of different services.

The QoS features of the MA5616 are as follows:

  • Dynamic bandwidth allocation (DBA)-based bandwidth management supported by GPON ports
  • Upstream GPON port supports eight T-CONTs and each upstream T-CONT supports four queues
  • T-CONT-based priority service in the upstream GPON transmission direction. Each service port has eight class of service (CoS) queues numbered from 0 to 7. Queue 7 has the highest priority and queue 0 has the lowest priority
  • Priority marking of the traffic-stream-based inner and outer VLAN tags
  • Access control list (ACL)-based priority marking
  • Three scheduling modes, namely, priority queuing (PQ), weighted round robin (WRR), and PQ + WRR
  • Mapping upstream/downstream services to different priority queues for scheduling based on the priority
  • ACL-based port rate limitation and traffic statistics
  • Two rate three color marker (trTCM)-based IP traffic profile and rate limitation on user port
  • Traffic shaping of port-level queue groups

5.Carrier-Class Reliability Design

The system reliability is taken into consideration in the system, hardware, and software designs of the MA5616 to ensure that the device runs in the normal state.

Hardware Design

The MA5616 supports the following functions:

  • Complying with carrier-class reliability specifications.
  • Featuring comprehensive exception handling capability.
  • Passing the electrostatic discharge (ESD) test.
  • Providing lightning protection and anti-interference functions.
  • Starting up at a low temperature of -25°C.
  • Enduring high temperatures and it can work normally for a long time at 65°C (the temperature is the temperature of the air intake vent of the cabinet).
  • Detecting the temperature. When the temperature exceeds the threshold, the system generates an alarm.
  • Protecting the subscriber port:
    • DSL port: 4 kV in transverse and port-to-earth directions, comply with K21
    • POTS port: 4 kV in transverse and port-to-earth directions, comply with K21
    • ISDN port: 4 kV in transverse and port-to-earth directions, comply with K21
    • GE port: 6 kV in common mode
  • Protecting the power: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. After the broadband service interruption feature is enabled, the broadband services are interrupted, and the narrowband services are normal.
    • DC: 3 kV in differential mode and 5 kV in common mode
    • AC: 6 kV
  • Controlling the fan. The speed of the fan can be adjusted intelligently. That is, the system can automatically adjust the fan rotating speed according to the working temperature, which has positive effect on reliable energy saving and noise reduction.
  • 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. A proper thermal design produces a temperature difference to prevent condensation.
  • Supporting H.248 dual homing. When the H.248 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 upstream link, the system automatically switches to the other MGC.
  • Supporting SIP dual homing. The MDU supports the 1+1 mutual assistance mode of the upstream P-CSCF/PROXY, that is, the deployment in the active/standby mode. When one of the upstream active/standby devices is faulty, the MDU service automatically switches to another device. Thus, the SIP disaster recovery scheme is implemented to improve the access reliability of the device.
  • Supporting the emergency standalone. When the MDU upstream port fails, the system automatically starts the emergency standalone function. Then, the subscribers of the same MDU can call and communicate with each other.
  • Supporting 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.

Software Design

The MA5616 supports the following functions:

  • Complying with the modularized and platform-based design concept, and adopts the loosely coupled design for each software module.
  • Adopting advanced design principles, such as object-orientation, error tolerance, error correction, and automatic recovery.
  • Complying with the capability maturity model (CMM).
