High serial interface wanted

[Jean-Michel Jouanigot]

Our project is to run TCP/IP at 8 Mbit/s on a satellite link.

We are desperately looking for a high speed serial interface that we could
plug into a VME crate (a sun for example). This interface should support
at least 2 Mbit/s, preferably around 8 Mbit/s. If possible, the interface
should be G703 compliant, and (lets dream) a SunOS driver should be
available.  If only 2 Mbit/s is available, the VME card would preferably
offer several such interfaces (4 is a minimum).

Information welcome,
Jean-Michel.
