The MA5680T series integrate the aggregation and switching functions, provide the high-densityxPON, Ethernet P2P, and GE/10GE ports, and provide the TDM and Ethernet private line services with high clock precision to support smooth Internet access service, video service, voice service, and high-reliabilityservice access. This series improve the network reliability, reduce the investment in network construction, and reduce the O&M costs.

The MA5680T series include the large-capacity SmartAX MA5680T and the medium-capacity SmartAX MA5683T. The hardware and software of these two models are fullycompatible with each other to reduce the costs of goods preparation for the network. In these two models, the SmartAX MA5680T provides 16 service slots and the SmartAX MA5683T provides 6 service slots.

Key Features

Large-capacity shared platform 

The MA5680T series provide the large-capacityshared platform that supports a high-speed switching capacity.

Developed based on the iMAP hardware platform and the IAS software platform of Huawei, the MA5680T series adopt advanced architecture and design.

The switching capacity of the backplane is up to 3.2 Tbit/s.

The bidirectional switching capacity of the control board is up to 480 Gbit/s.

The GPBD board supports eight GPON ports and the entire subrack supports up to 8K ONTs.

The EPBD board supports eight EPON ports. Based on the 1:64 split ratio, the entire subrack supports up to 8K ONTs.

Sharing the development platform with Huawei’s broadband access devices, the MA5680T series support the Layer 2 and Layer 3 features of the broadband access devices to provide user-oriented and future-oriented functions.

Powerful integrated GPON/EPON access capability

1. EPON access capability 

The point to multi-point (P2MP) architecture is used to support the passive optical

transmission over Ethernet. Symmetrical upstream and downstream rates of 1.25 Gbit/s are supported to provide the high-speed broadband services, meeting the bandwidth

requirements of access users.

In the downstream direction, the bandwidth is shared by different users in the encrypted

broadcast mode. In the upstream direction, time division multiplex(TDM) is used to share the bandwidth.

The MA5680T series support dynamic bandwidth allocation (DBA) with the granularity of 64 kbit/s. Therefore, the bandwidth of ONT terminal users can be dynamically allocated based on the user requirements.

The EPON system uses the passive optical transmission technology, and the optical splitter uses the P2MP mode and supports a split ratio of 1:64.

The supported transmission distance is up to 20 km.

The ranging technologycan be scheduled ranging, automatic ranging, or initial ranging.

 

GPON access capability

High rate is supported. The downstream rate is up to 2.488 Gbit/s and the upstream rate is up to 1.244 Gbit/s.

Long distance is supported. The maximum physical transmission distance of the ONT is 60 km. The physical distance between the farthest ONT and the nearest ONT can be up to 20 km.

High split ratio is supported. The 8-port GPON access board supports a split ratio of 1:128, which increases the capacity and saves the optical fiber resources.

High densityis supported. The MA5680T series provide the 8-port or 4-port GPON access

board to increase the system capacity.

The H-QoS (hierarchical quality of service) function is supported to meet the SLA

requirements of various commercial customers.

 

Powerful QoS capability

The MA5680T series provide the following powerful QoS solutions to facilitate the

management of various services:

Supports prioritycontrol (based on the port, MAC address, IP address, TCP port ID, or UDP port ID), 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 ID, or

UDP port ID) with a control granularity of 64 kbit/s.

Supports three queue scheduling modes: priority queue (PQ), weighted round robin (WRR), and PQ+WRR.

Supports HQoS, which assures the multi-service bandwidth for multiple users: The first level assures the user bandwidth, and the second level assures the bandwidth for each service of each user. This ensures that the assured bandwidth is allocated absolutely and the burst bandwidth is allocated fairly.

 

Comprehensive security assurance measures

The MA5680T series meet the securityrequirements of the telecommunication services, fully use the security protocols, and fully ensure the security of the system and the user.

1. System security measure

Protection against the DoS (denial of service) attack

MAC (media access control) address filtering

Anti-ICMP/IP packet attack

Source address routing filtering

Blacklist

2. User security measure

such as AES (advanced encryption standard) 128-bit encryption

GPON type B OLT dual homing

Smart link and monitor link for the network with dual upstream channels

Flexible network topology

As a multi-service access platform, the MA5680T series support multiple access modes and multiple network topologies to meet users’ network topologyrequirements on different

environment and services.

Carrier-class reliability design

The system reliability of the MA5680T series is taken into consideration in the system,

hardware, and software designs to ensure that the device runs in the normal state. The

MA5680T series:

Provides the lightning-proof and anti-interference functions.
