The access concentrator provides enhanced VDSL features while ensuring Seamless deployment in xDSL networks worldwide. The National Enhance Technology NV-800S access concentrator provides service providers an end-to-end, multi-service, video-centric network platform based on the most powerful and stable technology today.
The VDSL Concentrator networking solution delivers cost-effective, high-performance broadband access to multiunit buildings (hotels, Capus, apartment, and multi-tenant unit office buildings) and enterprise campus environments such as manufacturing, educational campuses, and medical facilities. VDSL technology dramatically extends Ethernet over existing Category 1/2/3 wiring at speeds 12.5 Mbps (full duplex) and distances up to 1200 meters, respectively. The VDSL technology delivers broadband service on the same lines as Plain Old Telephone Service (POTS), digital telephone, and ISDN system. In addition, VDSL supports modes compatible with asymmetric digital subscriber line (ADSL), allowing service providers to provision VDSL to buildings where broadband services already exist. already exist.< already exist.

The VDSL solution includes NV-800S VDSL Concentrator (VDSL CO switches), and NV-200 VDSL Modem for Customer Premise Equipment (CPE) device.

The VDSL solution delivers everything needed to quickly deploy an Ethernet-based network with the performance required to deliver high-speed Internet access at much greater distances and drive services like IP telephony and audio/video streaming. With this technology, a broad range of customers can benefit from lower operating costs and rapid deployment. The VDSL solution provides multicast, Layer 2 quality of sr 2 quality of service (QOS), Link Aggregation (LACP) dynamic trunking group, security, GVRP, IGMP for VOD (Video on demand) and SNMP RMON management and Web-based Switch network management.

The VDSL Concentrator is a bridge between external Internet backbone through a router for IP sharing and the building 110D telephone rack or telephone box. It utilizes the available telephone wire to enable high-speed Internet access to building residents.

The Concentrator uses the phone line networking technology endorsed by the VDSL (Very High Data Rate DSL), and the Concentrator utilizes the already existing telephone wire to deliver 10 Mbps Internet access on each RJ-11 port. This gives users a low-cost, end-to-end solution and eliminates the need to train installation teams on multiple systems. The NV-800S has 8 VDSL ports and 2 10/100 Ethernet ports. The switches is one rack-unit (1RU) high, 10-inches deep; it is a standard Rack mounted size. NV-800S switches deliver dedicated bandwidth per port at rates up to 12.5 Mbps.VDSL transmissions coexist with POTS and ISDN, and can be compatible with ADSL traffic in the same building.
