A.Anand Srinivasan,
I'm confused by the statement "No terminals are provided". Does this mean that the the black box has neither inputs nor outputs?

Re: black boxes

Yeah whats up with the "No terminals" thing. In that case the black box is just that simply a box, not quite usefull.

Did you perhaps mean that no extra terminals are supplied thus only the in and out ports are fitted on the box?
