| VideoBOX Combo 
 Bi-directionnal
        Multimedia Codec over ATM
 The SILICOMP INGENIERIE VideoBOX
        Combo represents a significant advance in the
        cost effectiveness of real world ATM application. By use
        of an innovative shared UNI, VideoBOX Combo integrates a
        number of mission critical business functions such as
        Video, Ethernet onto a single ATM channel, without the
        need for an ATM switch. The VideoBOX Combo
        technology removes the need for each unit to connect
        individually to an ATM switch port, by allowing many
        adaptation units to share the same ATM interface.

 Related Product VideoBOX Ethernet  The VideoBOX Ethernet is a "slave"
                module which is stackable on a "Master"
                or "Slave" VideoBOX Combo. Thanks to
                the VideoBOX Ethernet, it becomes possible to
                interconnect Ethernet networks between them over
                an ATM network LAN or WAN.
