VX1000EB system is the Packet Switching Concentrator most suitable for Internet Service Provider's residential gateway application. It is ideal for Multiple Dwelling Unit (MDU) Internet services such as hotel/motel, multi-tenant apartment, multi-tenant commercial, multi-tenant student dorm, campus, and local loop. The VX1000EB HomePNA packet concentrator utilizes the existing telephone wiring within a building to deliver data at mega-bit speed and does not interrupt regular voice services. Data and voice run simultaneously on the same pair of wire without any re-wiring. The system supports a Concentrator mode, where each of the ports 0-7 is only to directly communicate with the Uplink port #8 (9th Port). This mode ensures that data from any of ports 0-7 cannot be directly seen by another port. This feature is used in applications to provide data privacy to subscribers. VX1000EB is designed to eliminate unnecessary network traffic, and relieve congestion by delivering dedicated bandwidth for each of the ports. Able to begin operating after power-up, the VX1000EB will learn addresses automatically, and begin forwarding packets at full wire-speed to any of the eight outputs. The system also comes with future upgradeable capabilities with the expansion port, an optional up-link 100Base-FX/TX (Internal or External adapter. The system companions with the Management-Lite NMS and provides port based VLANs, and Quality of Service (QoS) via a parallel port that are usually associated only with high-cost fully managed switches. The built-in intelligence of configuration allows it to recognize and offer packet prioritization utilizing Network's QoS. Packets are prioritized based upon their Layer 2 VLAN priority tag or the Layer 3 Type-Of-Service (TOS/DS) field. This priority can be defined as transmit and/or drop priority. VX1000EB can operate stand-alone or can be cascaded with eight VersaXpress-900TX up to eight VX1000EB units to reach as 64+1 port-Switch MDU system. Below is the diagram depicting the typical application by using the VX1000EB The VX1000EB connects any desktop PC or Macintosh equipped with a 10Base-T network interface card (with VX110, 120 combo bridge) or a HomePNA LAN card by simply plugging into any RJ-11 jack. VX1000EB delivers true splitter-less data over voice and delivers an "always on" Internet connection.
