I need to connect a PC to a broadband coax style backbone. Management suggested a Hughes Probridge 8233 Bridge and and an ethernet card for the PC. When I saw the price tags, I knew I needed to look for other solutions. Are you aware of any PC adapter cards that will directly connect to this style of backkbone? If so, kindly post the info. Thanks, Jack Sharer, Penn State

Unless you're using 10BROAD36 then you may not have any alternatives. ( I assume that you want to communicate with machines on an existing ethernet channel) I'm not familiar with the Hughes system, so I don't know if it's 10BROAD36 compliant. Since most broadband ethernet products "Do it our way" instead of conforming to any kind of standard, it's very unlikely that anyone else will be compatabile with Hughes unless it's 10BROAD36 or MAP. Even if the Hughes system is "standard" you must then be sure that you order the proper TX and RX frequencies (assuming a single cable system) to communicate with existing equipment. If you are planning on installing a new "ethernet channel" be sure that you find out what frequencies are in use on the existing system so you don't end up ordering frequencies that collide with an existing broadband service (Video,Audio,Point to Point data, etc.) Dave Yoest Broadband/Fiber LAN M&O Section Supervisor Allied/Bendix field Engineering Co. at NASA/Goddard Space Flight Center Greenbelt, Md.
