NV-802S - 8 Port VSDL2 IP DSLAM

NV-802S - 8 Port VSDL2 IP DSLAM


NV-802S is a compact 8-ports VDSL2 IP DSLAM with 2 Gigabit Ethernet Combo interfaces and built-in POTS/ISDN splitter. It is compliant to ITU-T G.993.2 standard and supports VDSL2 30a profile that features 100 Mbps of symmetric data rate over the existing copper wires. NV-802S is an ideal choice for ISPs and System Integrators that are looking for a high performance broadband solution for their triple play applications. It offers a user-friendly management interface that allows service providers to monitor and control their services in a highly secure and efficient way. With many powerful and advanced features, this Mini IP DSLAM is the perfect solution for deploying broadband access, IP Surveillance, Hospitality and MTU/MDU applications.

Traffic Flow QoS Ensuring for Application Services
The VDSL2 Switch contains robust QoS features such as port-based, 802.1p priority and IP TOS/DSCP. It guarantees the best performance of VoIP and video stream transmission and empowers the enterprises to take full advantage of the limited network resources.

IEEE 802.1q Q-in-Q VLAN for performance & security

The VLAN feature in the switch offers the benefits of both security and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the broadcast traffic to within the same VLAN broadcast domain also enhances performance. VLAN support enabling advanced techniques such as 802.1Q-in-1Q to be deployed. And support GVRP up to 4k V-LAN groups.

Selectable VDSL2 Data Rate for Service Differentiation
Through the management interface, the administrator can control the data rate of each VDSL2 port. Telecom and ISP can immediately and remotely upgrade/downgrade bandwidth service upon different demands.

Broadcast/Multicast/Unknown-unicast Storm Control

To limit too many broadcast/multicast/unknown-unicast flooding in the network, broadcast/multicast storm control is used to restrict excess traffic. Threshold values are available to control the rate limit for each port. Packets are discarded if the count exceeds the configured upper threshold.

Powerful Layer 2 Features
For efficient management, via Web interface, the NV-802S can be programmed for basic switch management functions such as port speed configuration, port link aggregation, IEEE 802.1Q VLAN and Q-in-Q VLAN, port mirroring, Rapid Spanning Tree and ACL security. Additionally, the firmware includes advanced features such as IGMP snooping, QoS (Quality of Service), broadcast storm and bandwidth control to enhance bandwidth utilization.

Enhanced Security
The VDSL2 switch offers comprehensive Layer 2, Layer 3 and Layer 4 Access Control List (ACL) to filter out unwanted traffic. Its protection mechanisms comprise 802.1X RADIUS user and device authentication. Moreover, the VDSL2 switch provides MAC filter, Static MAC, and Port Security for enforcing security policies to the edge. Administrators can now build highly secure corporate networks have considerably less time and effort than before.

Last Mile of FTTx Deployment

The NV-802S is an ideal solution for FTTx (FTTB / FTTH, etc.) applications. It support high bandwidth over existing telephone wires in the “last mile” from the ISP / Telecom / Service Provider’s fiber node to the buildings and customers’ houses.

The Intelligent NV-802S provides a high speed, 100Mbps transmission over phone wiring over a single Internet account to provide simultaneous independent Internet access to multiple users. It is excellent for phone line network built under internet because the whole building could share the internet to the wider area network with minimum cost and get max efficiency.
