Huawei Scun Super Control Board, No. H801 H802 H802D Scun for Huawei Ma5680t Ma5683t Olt

Relate information:

Large-capacity shared platform
 
The MA5680T series provide the large-capacity shared 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 technology can be scheduled ranging, automatic ranging, or initial ranging.
 
2. 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 density is 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 priority control (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 security requirements 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
 
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
 
Flexible network topology
 
As a multi-service access platform, the MA5680T series support multiple access modes and
multiple network topologies to meet users' network topology requirements on different
environment and services.
