Key Features

 

Integrated Access

The MA5600T/MA5603T/MA5608T is an integrated optical-copper access platform that provides flexible user access modes and effectively ensures the smooth evolution from copper access to optical access.

Optical Access

The MA5600T/MA5603T/MA5608T supports 10G GPON access, GPON access and P2P access, which effectively meets requirements of various FTTx access applications.
  • Supports a split ratio of 1:128.
  • Support small form-factor pluggable (SFP) optical module of Class B+ or Class C+ and XFP optical module, which can be used in different scenarios.
  • High-density 48 single-fiber bi-directional or 24 two-fiber bi-directional GE/FE P2P optical access is supported.
  • Supports the high-performance and large-capacity control board SCUH. In active/standby mode, SCUH supports 20 Gbit/s switching bandwidth for each slot. In load sharing mode, SCUH supports 40 Gbit/s switching bandwidth for each slot. And provides 960G switching capacity (doubles performance capacity), improving access user bandwidth.

Copper Access

The MA5600T/MA5603T/MA5608T supports multiple xDSL access and POTS access modes and makes full use of existing copper cable resources to provide users with rich and flexible network services. The retransmission and INM functions solve the line quality deterioration problem caused by line bit errors and line noise, which ensures the line access quality.

  • The xDSL ports works with the ADSL terminal unit-remote end (ATU-R) or the VDSL terminal unit-remote end (VTU-R), which can provides the highest-density 64 channels of xDSL access and 48 channels of POTS access.
  • Far-end crosstalk (FEXT) is one of key factors affecting the performance and stability of the VDSL2 system. The MA5603T supports the vectoring feature. Vectoring uses vectors to solve FEXT of VDSL2 lines so as to improve bandwidth and performance of multi-pair VDSL2 lines. It effectively decreases crosstalk for short-distance lines (shorter than 1 km). The rate of a single VDSL line can be increased about 50%-90% within 800 m. Provides higher bandwidth and more types of services over existing VDSL2 lines after the rate for a single VDSL2 user is increased.

Full Service Access

This section describes the data, multicast, voice, and base station access services of the MA5600T/MA5603T/MA5608T and the QoS solution implemented by the MA5600T/MA5603T/MA5608T.

Centric Management for GE Remote Extended Subracks in FTTB or FTTC Scenarios

The MA5600T/MA5603T supports the centric management for GE remote extended subracks in FTTB or FTTC scenarios so that the network features higher scalability. The GE remote extended subrack feature uses new technologies such as VDSL2 and vectoring on the copper line network to deploy ultra-broadband networks more conveniently and rapidly.

Key Technologies

Intelligent Site

As large-scale fiber to the curb (FTTC) construction becomes popular, the number of outdoor sites grows rapidly. The remote integrated sites are provisioned with cabinets, power systems, temperature control units, and batteries. However, some maintenance works cannot be done remotely by the remote maintenance technology. Maintenance personnel need to be assigned to the sites, which results in low maintenance efficiency and high costs. This feature is introduced to solve this issue.

When the MA5600T/MA5603T is configured with the enhanced service management unit (SMU) power system, the following feature items are supported: Intelligent property management for the key components (including the cabinet, power system, temperature control unit, and battery) on the site and Intelligent floating charging management for batteries on the site.

Prominent Network Protection Function

  • Supports the MSTP protocol, featuring the loop protection function.
  • Supports the RRPP protocol, implementing rapid switching in a ring network.
  • Supports the LACP and inter-board aggregation features, increasing the bandwidth and providing the protection function.
  • Supports bidirectional forwarding detection (BFD), improving the reliability of IP applications (such as real-time voice service) and providing support to the network stability for service providers.
  • Supports the smart link application, which implements the redundancy backup and quick migration of active and standby links, ensuring the high reliability and high-speed convergence.
  • Supports Type B redundancy protection for the GPON, ensuring that the services are not interrupted when the backbone optical fiber is faulty.
  • Supports GPON Type C redundancy protection, improving the device reliability.

Superior QoS Function

The superior QoS can guarantee an expected service level with respect to bandwidth, latency, jitter, and packet loss in a communication network.

  • Tags the data and network management streams with different ToS/DSCP priorities, thereby providing a prioritized forwarding mechanism based on Layer 3
  • Tags the data and network management streams with different 802.1p priorities, thereby providing a prioritized forwarding mechanism based on Layer 2
  • Supports Layers 2-7 traffic classification based on the port, VLAN, MAC address, IP address, TCP port number, or UDP port number
  • Supports priority control (based on the port, MAC address, IP address, TCP port number, or UDP port number), priority mapping and modification based on the ToS field and 802.1p, and DSCP differentiated services
  • Supports bandwidth control (based on the port, MAC address, IP address, TCP port number, or UDP port number) with a control granularity of 64 kbit/s
  • Supports three queue scheduling modes: priority queue (PQ), weighted round robin (WRR), and PQ+WRR.
  • Supports the following QoS capabilities based on the flow rule:Supports hierarchical quality of service (HQoS), which guarantees the multi-service bandwidths for multiple users: The first level guarantees the user bandwidths, and the second level guarantees the bandwidths for the services of each user. This ensures that the guaranteed bandwidths absolutely pass and the burst bandwidths pass fairly.
