In response to this portion of your query:

........

	the cisco Systems Protocol Converter
	the Datability Vista VCP-1000

This posting is to request information from the assembled multitudes
of the network:

1. If any of you have purchased either or both of the above named
	devices, I'd love to hear accolades, curses, etc. relating to
	your experiences with them.

2. Who have I missed? Are there other products which might fill my
	need in this area?

         2) Will cisco routers talk to this SUN product and if so what has been
            the user feedback, if any?
