Ever hear of a self-routing fast packet switch? OK, it's not *exactly* the same. But it's an analog of an SXS. It's an interesting set of paradigm shifts -- from "central control" (an operator at a patchboard", to "distributed control" (an SXS), back to central control (central control XBs and ESSs), and (potentially) back to distributed control in fast packet switches... (one could potentially do a thesis on this.... I want the movie rights, tho :-)) David G Lewis ...!bellcore!nvuxr!deej "If this is paradise, I wish I had a lawnmower."
