    The new iDirect Hub Chassis Line Card supports

    network speeds of 18 Mbps Downstream, and 4.2

    Mbps Upstream.

    A single 20 slot Hub Chassis supports aggregate

    speeds of 360 Mbps.

    By simply adding a separate line

    card, the iDirect solution can

    support different topologies

    from the same chassis

    It can also support multiple

    satellite links
