8-Port Managed VDSL Concentrator
Product ID: NV-800S
8-Port Managed VDSL Concentrator

The NV-800S Managed VDSL Concentrator provides an intelligent solution for delivering network and broadband services to the SOHO and MTU/MDU with speeds up to 15Mbps and distances up to 5,000 feet (1524m) over existing phone lines.

The Netsys Low-Density VDSL solution including the NV-800S Managed VDSL Concentrator and NV-200 VDSL CPE (Customer Premise Equipment) Modem delivers everything needed to quickly deploy a high-speed Ethernet-based network for providing high-speed Internet access and video-on-demand services, in addition to voice services. The NV-800S' 10/100 Ethernet Uplink Port connects to a Router or Ethernet Switch and acts as the bridge to the Internet for end-users connected through the NV-800S' 8 VDSL ports. The second 10/100 Ethernet Uplink Port may be used for cascading additional NV-800S units or connecting to a video-on-demand server or other IP capable system for distributing content to the end-user. The NV-800S also features built-in POTS/ISDN splitters so that the VDSL service can share the existing phone line with the end-users' POTS/ISDN telephone service, thus reducing cost and overall wiring requirements. The POTS/ISDN lines and VDSL links connect to standard RJ-11 connectors on the front of the NV-800S and are broken out on the end-user side by the NV-200 CPE Modem, which features one 10/100 Ethernet Port and one POTS/ISDN Port. For higher density applications, the Netsys NV-2400S 24-Port Managed VDSL Concentrator and standard Ethernet Switches (like the Netsys NS-2024S Gigabit Ethernet Switches) can be used to provide additional expansion.

The intelligent web-based management software, allows for streamlined configuration of the NV-800S, as well as NV-200 CPE devices through a single IP address. The NV-800S can be configured on a per-link basis to support 5 Mbps up to 5,000-feet (1524m), 10 Mbps up to 4,000 feet (1219m) and 15 Mbps up to 3,200 feet (975m). Additionally, the signal-to-noise ratio (SNR) feature can be utilized as an indication to the service provider as to the quality of the link between the NV-800S and the CPE.

The NV-800S is also a fully managed layer 2 switch that offers quality of service (QOS), link aggregation dynamic trunking groups, multicast, security, GVRP, IGMP for VOD (video on demand), SNMP RMON and web-based switch network management. The NV-800S provides high and low priority queuing per port based on 802.1p QOS. The NV-800S provides security through 802.1Q port-based virtual local-area network (VLAN) and supports port based network access control.

The NV-800S provides comprehensive hardware diagnostics and is easy to maintain. The NV-800S is one rack-unit high, 10-inches deep (254mm) and can be easily mounted in a rack/cabinet or placed on a desktop. The resulting compact, cost-effective form factor offers systems integrators, small business and building owners an attractive low-density VDSL solution.
