World's First 10/100 Ethernet Switching Hub for Embedded PC/104 Systems Unveiled by parvus Corp.; parvus Launches New Fast Ethernet Hub With Five Auto-Configurable Ports.Business Editors & High-Tech Writers SALT LAKE CITY--(BUSINESS WIRE)--May 20, 2002 parvus Corp. today announced the unveiling of its 10/100 Ethernet Switching Hub -- the first Fast Ethernet An earlier name for 100Mbps Ethernet. See 100Base-T. (networking) Fast Ethernet - A version of Ethernet developed in the 1990s(?) which can carry 100 Mbps compared with standard Ethernet's 10 Mbps. It requires upgraded network cards and hubs. switching hub A device that acts as a central switch or PBX, connecting one line to another. In a local area network (LAN), a switching hub gives any two stations on the network the full bandwidth of the line. available for embedded Inserted into. See embedded system. PC/104 applications. The embedded board allows up to five devices using 10BaseT or 100BaseTX Ethernet interfaces to communicate over a network or the Internet, while achieving outstanding performance, integration, and power management from its PC/104 form factor. Two Ethernet connector options are available for the board -- with local RJ-45 jacks (Board #: PRV-1059X-01) or Molex 4-pin panel mount connectors (Board #: PRV-1059X-02). Enabling full-bandwidth 10/100 Mbps switched access, this Fast Ethernet Hub offers five 10/100 transceivers and independent Fast Ethernet media access controllers, a high-speed non-blocking switch fabric and address look-up engine, and a 1 Mbit embedded frame buffer An area of memory used to hold a frame of data. Typically used for screen output, the buffer is the size of the maximum image that can be displayed on the screen. The memory, which is either a separate memory bank on the display adapter or a reserved part of regular memory, holds a memory. Its shared memory-based switch fabric provides non-blocking switching performance for all data traffic environments, including back-pressure and pause frame flow control schemes. Pricing for 100+ units is $134 each. Features & Specifications -- 5 Auto-configurable ports (straight/twist) -- Auto-negotiation and speed auto-sensing -- Back pressure-based flow control of half duplex ports -- IEEE 802.3 and 802.3u compliance -- Highly integrated DSP-based 10/100 switch -- LED activity indicators -- Look-up engine supports as many as 4,096 MAC address entries -- Pause frame-based switch fabric delivers true non-blocking switching -- Data Transfer Rates: 10 or 100 Mbps -- All ports can work at full/half duplex RJ-45 or Molex 4-pin connectors -- Simple networking installation through auto-MDI/MDIX -- Store-and-forward switching mode -- Operating Temperature (0(degrees)to 70(degrees)C) -- Storage Temperature (-40(degrees)to 85(degrees)C) -- Dimensions: 3.550" x 3.775" -- 16-bit PC/104 (ISA bus) Applications The Ethernet Switching Hub can expand a 10BaseT or 100BaseTX system beyond two nodes or increase local area network (LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. ) distances beyond the 100-meter limit of the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.3 specification. Potential applications include machine monitoring, process control, test and measurement, environmental control, remote data acquisition, and communications gateways in avionics/aerospace, defense, factory automation, medical, telecom and transportation fields. parvus also plans to unveil a PC/104-based 10/100 Ethernet Network Interface Card (NIC (1) (Network Interface Card) See network adapter.
