        optic technology using familiar Ethernet protocol and
        fiber adapter cards from the world leader, Allied
        Telesyn. Fiber features security, dramatically extended
        distances and more efficient network management. Extend
        network segments to 2 kilometers. Ideal for use in
        "electrically noisy" environments and in
        backbone or campus environments where longer cabling
        distances are required.  Allied Telesyn's AT-2450FT adapter
        cards connect high performance computers with a PCI
        architecture to Ethernet over fiber networks. The PCI Bus
        Master architecture minimizes CPU utilization, freeing
        your computer's power for the most memory-intensive
        applications. These high performance adapters, utilize
        the 32-bit PCI bus architecture which transfers data at
        speeds up to 33Mhz and has data throughput rates as high
        as 132Mbytes/second, up to 16 times faster than the
        traditional ISA bus. Both high-speed systems and
        applications requiring transfer of multimedia and video
        data will benefit from this solution. Full-Duplex
        operation enables the AT-2450 to transmit and receive
        data simultaneously. Quick, Easy InstallationThe AT-2450 Series PCI adapter cards
        are auto-configurable, dramatically reducing installation
        time. Allied Telesyn gives you the industry's only
        "On-Line-Help" feature in addition to
        diagnostic software and four visible LEDs to assist in
        installation and troubleshooting. The cards are available
        with a RJ45/UTP connector for copper and a fiber
        connector; ST (twist-on) connector, or the new SC
        (push-on) connector. The media port automatically senses
        which media is active when the network cable connector is
        attached, eliminating software set-up programs. CompatibilityThe AT-2450 is fully compatible with
        PCI v2.1, IEEE 802.3 and ISO/IEC 8802-3 specifications. A
        full set of certified network drivers is included for the
        most popular operating environments in the industry. Superior SupportAllied Telesyn offers a lifetime
        warranty with advance replacement and free unlimited
        technical support. Updated and enhanced drivers and
        features are available 24 hours a day on the Allied
        Telesyn website, BBS and ftp server. Included FREE of
        charge is McAfee VirusScan for Windows 95, the world's
        best virus detection and removal software. For added
        network integrity and security, a BootROM socket and
        BootWare are available for centralized software
        distribution or remote booting. Technical
