Large-capacity platform with Access and Aggregation Integration

• Developed based on the iMAP hardware platform and the IAS software platform of Huawei, the MA5600T series product takes on the advanced architecture and design.
• The switching capacity of the backplane is up to 3.2 Tbit/s, and the bidirectional switching capacity of the control board is up to 480 Gbit/s.
• High density GE/10GE interfaces for cascading, up to 36*10GE or 384*GE interfaces, no need for additional investment of aggregation switches.
• Each GPBD board supports eight GPON ports, based on the 1:128 split ratio, the single subrack supports up to 8K ONTs. In 2012, Huawei will launch 16-port GPON board which can supports 16K ONTs.
• Sharing the development platform with Huawei's broadband access devices, the MA5600T series product support the Layer 2 and Layer 3 features of the broadband access devices to provide user-oriented and future-oriented functions.
• GE/GPON/NGPON coexisting on the same platform.
• Aggregation switches.

Comprehensive security features

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

• DHCP (Dynamic Host Configuration Protocol) Option 82 to enhance the DHCP security.
• Binding between MAC/IP addresses and ports.
• Anti-MAC spoofing and anti-IP spoofing.
• Authentication based on the serial number (SN) and password of the ONU/ONT.
• Triple churning encryption.
• Encrypted broadcast transmission in the GPON downstream direction for different users, 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.

High reliability design

• Adopts 1+1 redundancy backup for the control board and the upstream interface board.
• Provides the lightning-proof and anti-interference functions.
• Supports fault pre-warning on the exhaustive (consumed) units and parts, such as the fan, power supply, and battery.
• The 1+1 (type B) protection for the PON port and the 300 ms level service protection switchover for the backbone optical fiber are supported.
• Supports main control board in-service upgrade .
• Supports high temperature detection to ensure the system safety.
• The functions of querying the board temperature, setting the temperature threshold, and high temperature shutdown are supported.
• Supports hot swappable for all service boards and the control boards.
• Provides soft-start circuit, protective circuit, current-limit protection, and short circuit protection for the input power of the boards in the subrack to protect the boards against lightning strikes and surges.
• Supports GPON type C OLT dual homing.
• Supports smart link and monitor link for the network with dual upstream channels.

Green

• With Huawei self-developed GPON chipsets, the maximum power consumption of the 8-port GPON line card is only 51W.
• Unique energy-saving bus, the idle service card can be powered off.
